㈡ Let’s talk about blockchain while it’s hot

Let’s talk about blockchain while it’s hot
Blockchain is popular again
The Internet has become Victoria's Secret's T stage. Big bosses are wearing technical underwear, posing and showing off their sexiness, and their leg hair is fluttering in the wind, black and shiny.
At the end of 2017, blockchain became the sexiest little underwear. Everyone from all walks of life has one, some wear it on the crotch, some put it on the head, and some put it on a pole as a flag.
Staring at the smart contract code on the screen, I felt a little melancholy. There was no me on the catwalk, and there was no me off the catwalk. I was in an office with insufficient heating, and I was still wearing a down jacket that had nothing to do with sexiness.
This morning, I met Aunt Niu in the community. She pulled me and warned me earnestly, stop writing Java and start working on blockchain. Concept stocks have gone crazy. It was 7 o'clock in the morning, and the temperature was minus 10 degrees Celsius in the community. However, there was an inexplicable smell in the air. It smelled of vitality. It was probably that there was some kind of stimulant in the exhaust gas emitted by the natural gas boiler.
I feel powerless and helpless. This wave of heat has absolutely nothing to do with me. My few lines of smart contract code have made no contribution to the blockchain, an Internet celebrity in 2017. The big guys on the catwalk, again, didn’t ask me to “come with you,” as they always do!
The popularity of blockchain is inexplicable. It seems that just in an instant, the situation a few months ago was completely different. At that time, artificial intelligence was the protagonist, and blockchain was like a daughter-in-law married to a Shandong family, unable to gain publicity. Once at the dinner table, a VC boss (not a big one, not a big one) introduced his investment direction: "It must be artificial intelligence, not blockchain." He stared at me with bright eyes. I lowered my head, a little ashamed. If this was on Weibo, I would kill you. You can look down on me as a person, but you can’t look down on the technology I use, right?
However, just recently, this big guy (not a big one, not a big one) started to read articles about blockchain by Xu Xiaoping and Ma Huateng, and commented: "Profound and good article! Blockchain that changes the world chain!". I don’t know about this big guy (not very big), semi-large or not) are we going to launch the blockchain brand?
I have always suspected that there is a mysterious "Internet Noun Hype Committee", that is, they are making waves, hyping various concepts in waves... and the VC boss I met (not Very large, semi-large not large), probably not on this committee.
Artificial intelligence VS blockchain, who should win the chicken?
Artificial intelligence and blockchain are the two most popular concepts in recent years.
If you have to compare, who is more powerful, artificial intelligence or blockchain?
When it comes to artificial intelligence, humans tremble, saying they are afraid of being taken over by machines one day. This is a bit like a domestic pet dog. When it sees a fly with a broken wing, it feels like it is facing a powerful enemy. It opens its teeth and claws and jumps up and down, barking. In fact, it is usually too boring and looks for an opportunity to scare itself. Whether it’s artificial intelligence or robots, it’s still early to take care of a fly, let alone humans. Let’s look a hundred years away. I think that if our country’s GDP ranks first in the galaxy, it will come sooner than artificial intelligence will have self-awareness.
When it comes to blockchain, those who tremble are the centralized authorities, including governments of various countries. This is really not a game of puppies catching flies. Think about it, how much wealth is now hidden in the Bitcoin chain, but governments are powerless, helpless, helpless, and hate it. Flies are also meat. Seeing the flies getting fatter and fatter, the puppies can't catch them and they are worried to death.
So, in the long run, artificial intelligence must be much more powerful. The baton of future technology will be handed over from humans to AI. Isn’t this enough to make AI stinky?
But in the near future, the significance of blockchain is even more significant, because its goal of changing is the human organizational model.
Blockchain eliminates centralized power; Blockchain builds a network of trust; Blockchain uses code to transmit value; Blockchain coordinates dialogue between machines; Blockchain realizes community autonomy. There has never been a savior, nor a fairy emperor - this lyric can be given to the blockchain. For thousands of years, the functioning of society has relied entirely on the arrangements of centralized authoritarian institutions. Now, finally, there is a glimmer of light on the horizon of technology...
Whatever it is, in the eyes of the Chinese nation , the first question is: can this thing be eaten? The second question is: can this thing make money?
Of course, blockchain cannot be eaten. I don’t need to answer this. Just ask your Guangdong friends. If you want to ask whether artificial intelligence or blockchain is better at making money, I really can’t answer it, and the people of Guangdong don’t know either. This question should be asked to the VC boss (not a big one, half a big one).
When Satoshi Nakamoto was working on “a peer-to-peer electronic cash system”, it was really not for money. Those big guys (really big, no big deal) in the cypherpunk group are all genuine rebels.Just go against the government! What I pursue is a feeling of freedom. Starting with the three buddies from RSA, as long as they are engaged in cryptography and are not within the US government system, which one is not a thorn in the side of the US government? This is also talking about the U.S. government. If it were any other government, oh my God, the blood would be cold and the grass on the graves would be covered with grass.
There is another wave of big guys (really big, no big deal). They are Mises and Hayek, a group of economists who are deeply hostile to governments of various countries. Hayek believed that the right to issue currency should not be monopolized by the government. The government has no ability to control the issuance of currency, and the issuance of currency should be left to the free market. Letting the government issue currency is like asking rats to cook delicious food. First of all, rats cannot cook at all. Secondly, rats will steal the raw materials. Hayek said: Anyone can issue currency, and multiple currencies should be allowed to compete freely in the market.
Hayek's consistent core idea is that there has never been a savior or a fairy emperor who can formulate and control the rules for economic operation. These rules have evolved unconsciously in the free market.
Leave it to the free market. There are some things that humans cannot understand and cannot operate well.
The core idea of ​​Hayek is also the core idea of ​​artificial intelligence and the core idea of ​​blockchain. Why such a coincidence? Because, awesome people all have the same ideas, while non-awesome people have different ideas.
Artificial intelligence says that this function is too complex for humans to find. Let the machine find many linear functions to fit it. Leave it to the machine.
Blockchain says that trust is something that cannot be trusted by humans. It is better to let machines execute the agreed rules.
Giving power to machines is a common philosophy of artificial intelligence and blockchain.
At this point, we can point out sharply and wisely that artificial intelligence and blockchain actually do the same thing. Blockchain opens the way for machines in terms of organizational form. Artificial intelligence paves the way for machines in terms of capabilities. Human beings' organizational forms and abilities are too old, and it is time to make some changes for the future machine civilization.
For developers, blockchain is easier to get started with. Artificial intelligence is too troublesome. It requires data, a graphics card, and modeling and adjustment to see the effect. Therefore, if you are a poor programmer and want to make a little money, just engage in blockchain. Programmers with dreams and desire to make big money, please go to the right. The artificial intelligence channel is on the right. Please close your eyes and walk in unison, one, two, three, jump!
What can blockchain do?
At this stage, what is the most appropriate use of blockchain? My answer is marketing! In other words, it is most suitable to use it to deceive.
It is said that there are now 5,000 companies across the country related to blockchain. It is also said that there are a total of 200 developers in the country who can develop blockchain.
I don’t think either of these numbers is very reliable. I think a reliable statement is that the National Communist PartyThere are 5,000 company CEOs who have read popular science articles about blockchain in their circle of friends, so their companies are all related to blockchain. As for developers, if they can run Hyperledger, Ethereum, and write a few lines of smart contracts, there must be 5,000 of them in the country.
It is also said that in 2017, the revenue brought by blockchain technology did not exceed 100 million yuan.
So, just listen to the overwhelming propaganda now and don’t take it too seriously. At this stage, this kind of publicity is not a bad thing, and it can be regarded as promoting the development of the industry. With four people carrying the sedan and thousands of people cheering, it can always go a little faster, and the cheerleading team is not without its contribution.
Moreover, the development of blockchain has indeed been promoted. I’ve been asked by 50,000 people: What can I do with blockchain?
After being fooled, everyone began to stare at the centralized systems of their own homes, with doubts in their eyes. Just like when a new season begins, women take stock of their wardrobes.
Actually, there is no need to like the new and dislike the old. What the blockchain wants to get rid of is centralized “organizations”, not centralized “systems”. You can use your OA however you want. There is no need to use blockchain for your own OA system. Just like your family business, it's time to vote for the chairman. Aren't you out of your mind?
To use blockchain, you first need to think about who you want to reach a "consensus" with and on which business? With whom and at what stage are you trying to gain "mutual trust"?
The core is "consensus".
Of course, the blockchain can also be non-stop, which is what Ethereum hypes. But in my opinion, it's really not that important. Once the centralized system is ready, it is almost as close to never shutting down.
Give an example of blockchain application. A common and easy-to-understand example is the scene of signing a contract. When we sign contracts now, we still rely on paper contracts. Sign and seal the paper contract and make it in duplicate, with each party holding one copy. This is a "consensus" that occurs in the real world.
"Paper" and "Signature and Seal" are to prevent tampering. And "two copies" means distributed storage.
If you want to use software to perfectly realize the process of signing a paper contract, that is the blockchain. "Paper signature and seal" is implemented on the blockchain through technologies such as timestamps, hash operations, and asymmetric encryption signatures. "Distributed storage" is completed through POW, POS consensus algorithm and P2P protocol.
The software implementation of the above entire process is the achievement of a blockchain “consensus”.
With the development of IT technology and Internet technology to this day, cash has been replaced by electronic payment, but contracts have always been a big problem, and the paper contract process has always existed stubbornly. Now, blockchain isIt is here to subvert stubborn scenarios like paper contracts.
Let’s give another example. Scenarios of points exchange. I don’t know why, but at the end of 2017, making points suddenly became popular, and every household wanted to make points. I secretly guessed that maybe the King of Chu had a slim waist, and the Holy Will of the King of Chu was cracked by the "Internet Noun Hype Committee". In the early years, wasn't our "work points" just a kind of points.
Of course , Commercial points are very mature in many countries. For enterprises, points are a good customer loyalty management tool, but they have not been implemented in our country. Therefore, it is a good direction to develop commercial points.
The example is this. Two companies, A and B, have issued their own points, let's call them A points and B points. The two companies want to share points so that consumers can use A's points at B and use them at A. B’s points are used there.
This creates a scenario where a consumer comes to Company B and uses A’s 1 million points to buy a Porsche. Under the traditional centralized system, Company B’s system would Connect to A's system through the API to verify the identity of the mouse under the lamp and the number of points. After verification, request A's system to consume 1 million A points. With A's consent, A's system records that B has consumed 1 million points. B records in his own database and receives 1 million points from A.
At the end of the month, B takes a report of 1 million points and goes to A to settle the bill. A queries the database and confirms that 1 million points have been received by B There. OK, the settlement is successful.
The question is, what if A does not recognize the 1 million points? What if A denies it? What if A changes its own database? If it is more complicated, with multiple companies involved, B receives A’s points can also be used by C to consume A’s points. How to deal with this?
Blockchain can perfectly solve this problem. The two companies A and B can trade points in near real-time through the alliance chain. Reach a consensus. There is no need to go through reconciliation procedures at the end of the month. At any time, the blockchain data of A and B are consistent.
Some developers want to get into trouble: I use the traditional centralized system, the same It can ensure that the database is consistent.
Of course it is possible. But as long as you do it perfectly and make the databases of A and B completely consistent and solve various possible problems, then in fact, you are developing a Blockchain.
Achieving "trust" and "consensus" among multiple parties is where the blockchain comes in.
Satoshi Nakamoto designed Bitcoin entirely to design a Decentralized electronic currency. From this, the blockchain was born.
With Ethereum, the blockchain has transformed into IT infrastructure. Ethereum is the driverThe value measurement of blockchain applications, and the smart contracts on Ethereum are the protagonists of the chain.
Theoretically, smart contracts can develop any system. Smart contract in English is Smart Contract, and the “intelligence” here has nothing to do with the Artificial Intelligence of AI. In fact, when Nick Szabo proposed smart contracts in 1995, it had nothing to do with blockchain. Its concept was very simple, which was to write legal provisions into executable code.
But chocolate goes best with rainy days, and smart contracts go best with blockchain. As mentioned above, contracts must be made in two or four copies. Since smart contracts are legal provisions and must be automatically executed, of course they cannot be controlled by one party to the contract. Distributed storage must be implemented to reassure all parties involved. This is the so-called decentralization.
Today, applications using blockchain and smart contracts are mainly concentrated in the following fields:
Financial field: used to make digital currency; used to make payment systems; used to make remittances System; used for clearing system; used for securities trading system; used for supply chain finance.
Asset description: Used to register assets, such as real estate and land registration, and valuables registration.
Insurance products: used for mutual insurance and other insurance products with simple terms.
Identity authentication: used for personal and corporate identity information storage and online authentication.
Supply chain: used to trace the origin of goods and track the production process.
Government affairs: used for voting; used for official document storage; used for property rights registration.
Of course it can also be used to make games, such as making a blockchain to raise cats, dogs, and frogs, or you can also try raising men?
No matter what you do, before you decide to enter the blockchain, before you decide to start searching for "blockchain", remember my words, you must promote it first, and use it to make the whole world listen. A loud voice shouted: We are doing blockchain.
The current status of blockchain technology
What it can do and how well it does it are two different things.
The most mature applications of blockchain are naturally systems such as Bitcoin and Ethereum. In the field of commercial applications, it can only be said that everyone is still groping.
Many reports say that xx company’s blockchain application is online. In fact, most of them just run a chain in their own homes, or in an alliance of several companies, in their respective laboratories. I haven’t seen any application that releases chain data directly.
At this stage, the application of smart contracts is also used in conjunction with centralized systems. It is rare to implement all business logic on smart contracts.
Most of those who are proficient in using blockchain are entrepreneurial companies. People who can write a chain by themselves probably don’t bother to work.
Large-scale, high-capacity applications, such as e-commerce, are almost never implemented using blockchain. completeAt this stage, blockchain still has efficiency and capacity issues. But I think it won’t be too long before it actually comes true. Although it is still "just listen to the sound of the stairs and no one comes down", once someone comes down, the room will be filled with followers.
In less than 10 years, blockchain will become a commonly used technology, just like relational databases today.
But blockchain is destined to be different from relational databases, mobile and big data technologies. It is on the same level as the Internet, or even beyond the concept of the Internet. Because it challenges the human organizational model and changes the human organizational model.
Today’s Internet is so prosperous and has changed human life so drastically, but it has not changed the human organizational model. E-commerce is very developed, but it has only moved the market from community stores and supermarkets to Taobao and Amazon. The bank is still the same bank, and Alipay and WeChat are just another bank; the intermediary is still an intermediary, and the Taobao store is just the online form of the store; if you want to prove that you are your parents' moth, you still have to go to the police station to get a stamp, and nothing has changed, and There were few differences in the Ming and Qing dynasties. Taking "people" as the center to execute judgments and make decisions has remained unchanged for thousands of years.
It’s time to hand over part of the work to machines.
When blockchain technology developed for 50 years, people looked back and were surprised to find that so many institutions had disappeared before they could appreciate the significance of the blockchain in 2107.
In 10 years, blockchain technology will account for one-tenth of the workload in development. This is my estimate. It may not be accurate. I will make a wild guess first, just in case it is accurate.
As mentioned above, smart contracts and blockchain are the best match. Smart contracts are like knights, and blockchain is like a horse.
Blockchain also has a perfect match, and that is the Internet of Things. How should we do the interconnection of all things, the dialogue between things, and the transactions between things? It is perfect to use the decentralized storage of blockchain and the consensus algorithm of blockchain. However, that is still far away. When blockchain is combined with the Internet of Things, my country’s GDP will definitely already be the first in the solar system.
How should I apply blockchain
As mentioned above, the first thing to do when using blockchain is to make a loud noise and let the whole world know that you are using blockchain. Do your own marketing, and on the other hand, promote the development of the industry.
The second thing is to look at your own business and see where you need to reach consensus and mutual trust with others. Once you find it, that’s where you use blockchain.
But remember, you must be cautious when applying blockchain today. This is still very different from developing systems with relational databases and JAVA.
You must analyze and design carefully before taking action. Which open source blockchain to use, whether it is a public chain deployment or a private chain deployment, how to design the smart contract, how to interface with the centralized system, how to run it after it goes online, how to maintain it,These need to be considered carefully.
In fact, there are only a few technical routes that can be chosen, such as Bitcoin, Ethereum, Hyperledger, and Quorum. There are not many options.
You can also find domestic blockchain companies and use their chains directly. Some companies’ chains are also very reliable. Many companies such as Qulian and Bubi are serious about making chains. However, as far as I know, domestic chains are all modified from those international chains.
If you want to do it yourself, find two engineers with strong research capabilities and learn Ethereum or Hyperledger from scratch. In about two or three months, you should be able to write smart contracts and make Dapps. If you still can’t , just fire them and recruit two more. If you are ambitious and want to modify the chain protocol yourself, it will be more difficult to start from the source code. You will have to find a few Ph.D.s who are good at mathematics and proficient in algorithms and work hard for a year or two. In fact, changing the chain source code is also a conscientious job. If you change more or less, only you will know as long as you don't release it.
Before taking action, it is best to find someone who has done blockchain projects and consult with them. Maybe a word from someone can save you 3 months of effort. You know, on the vast Internet, there is really no mature application solution for blockchain, and everyone is groping for it.
The biggest challenge is: how to use blockchain technology to implement my application scenarios.
Everyone is groping in the dark, and the only way to succeed is to turn on a light. When thousands of lights light up and the room is brightly lit, blockchain technology will no longer be uncommon.
What I’m afraid of is that after touching it, the light will be in vain. If I just touch the fluttering leg hair, but can’t touch the light, everyone will become discouraged, disperse, and stop touching. The artificial intelligence has been dispersed several times. In recent years, it has regained its confidence and continued to explore. The leg hair of the big guys once again shone in the dark.
What can I get from using blockchain
For engineers, if they master blockchain technology, of course their salary will increase. Blockchain talents are still very scarce today.
For a company, if it uses blockchain, don’t just watch the blocks being mined out and have fun on your own. It must be promoted widely. The brand will be improved, sales will increase, and the stock price will increase. Market value will skyrocket.
In the final analysis, stock price and market value have little to do with blockchain technology. They have risen because of the good deception technology. Those big guys, that is, the members of the "Internet Terminology Hype Committee", if they don't speculate on blockchain, they will speculate on AI, and if they don't speculate on AI, they will speculate on iOT. In short, there will be no shortage of ingredients in their frying pans. of. How to cheat, how to get money, money is falling from the sky.
I really like blockchain technology, and I don’t have a godfather in the “Internet Hype Committee”, so don’t think too much about it. Diaosi should avoid being greedy. Don't think about money. Use it first and then talk about it. You can get a taste of it even if you don't get any discount.
In 2013, a group of people in WangjingIn a small office, I chatted with a few friends and talked about using Java FX to build a Bitcoin trading website. A friend said: "Bitcoins are going crazy right now. They cost more than 200 yuan each. It's good to be an exchange."
I liked Bitcoin at that time because of its anti-thief temperament, but I didn't purchase. Neither did the exchange.
Now I regret it, but not just because I missed the profit opportunity of Bitcoin’s rise. But I reflected and came to a conclusion, that is, although I kept saying that I loved freedom, in fact it was just Mr. Ye who liked dragons. When a utopia of freedom was placed in front of me, I did not cherish it and did not dare to walk in. I didn't buy Bitcoin, which is a good example.

㈢ What is blockchain and how to introduce blockchain in a simple and easy-to-understand manner

Blockchain is a term in the field of information technology.

Essentially, it is a shared database. The data or information stored in it has the characteristics of "unforgeable", "full traces left", "traceable", "open and transparent" and "collectively maintained". . Based on these characteristics, blockchain technology has laid a solid foundation of "trust" and created a reliable "cooperation" mechanism, which has broad application prospects.

On January 10, 2019, the Cyberspace Administration of China issued the "Blockchain Information Service Management Regulations". On October 24, 2019, during the 18th collective study session of the Political Bureau of the CPC Central Committee, General Secretary Xi Jinping emphasized that “blockchain should be used as an important breakthrough for independent innovation of core technologies” and “accelerate the development of blockchain technology and industrial innovation.” . "Blockchain" has entered the public eye and become the focus of society.

On December 2, 2019, the word was selected into the top ten buzzwords of 2019 by "Biwenqiezi".

(3) Brief extended reading of blockchain slogan:

Blockchain financial application:

Since 2016, Major financial giants have also taken notice and launched blockchain innovation projects one after another to explore the possibility of applying blockchain technology in various financial scenarios. In particular, Puyin Group took the lead in pioneering the “blockchain+” standard digital currency.

The standard digital currency is an asset that has been identified, evaluated, confirmed, insured, etc. by a third-party organization and written into the blockchain through rigorous digital algorithms to form a standard correspondence between the asset and the digital currency. relationship, called a standard digital currency.

In order to realize the great leap forward development of blockchain finance, in order to promote the new development of China's economy, accelerate the circulation of global assets, and realize the dream of rejuvenation that generations of people have been striving for, Puyin Group will Puyin Blockchain Finance Guiyang Strategy Release Ceremony was held in Guizhou on the 9th;

At the meeting, the digital circulation of assets through blockchain, the blockchain financial transaction model, and the relationship between blockchain services and blockchain services will be discussed. The application of social public industries will be discussed. This conference will mark the beginning of the application of blockchain finance and a new financial ecosystem.change and development.

㈣ What are the relevant terms about the blockchain industry

1. Practical tokens

A utility token is a utility token that acts as a right to use a specific service.

Examples of term usage

Utility tokens are predicated on using a service.

Details

You can settle the price of goods and meals instead of cash, or you can access it by having cloud storage. For utility tokens, classification of audit reports is not required.

6. Public chain

A public chain is a highly "public" blockchain where anyone can freely participate in the network.

Examples of term usage

As an infrastructure project that mediates the exchange of data between blockchains, a mechanism for exchanging data on a public blockchain will be established.

Details

In a blockchain used to record transaction information for crypto assets (virtual currencies), this is a mechanism used by an unspecified number of participants to Consensus builds transaction information without a specific governing entity. It is very safe to prevent forgery of transaction information, but it requires a lot of calculations, so its disadvantage is that it takes a long time to complete the transaction when there are many participants.

7. Scalability problem

Scalability problem refers to the "scalability" problem that delays transaction processing.

Examples of term usage

Spiking gas prices have highlighted Ethereum’s scalability issues.

Details

Due to the nature of blockchain, there are processing delays due to the limited amount of transaction data that can be written in a block. Sending money can take a long time, which results in higher transaction fees. Bitcoin, the first cryptocurrency to be created, has been recognized as a special problem, but efforts to solve it have been implemented, such as leveraging other technologies such as the Lightning Network and developing new blockchains.

8. GAS fee

GAS fee is the (network) transaction fee on the Ethereum blockchain.

Examples of term usage

This week, there were multiple cases of high gas bills being paid on the Ethereum blockchain despite small remittances.

Detailed description

The user-specified amount of GAS fee is a secondary reward. The virtual currency Ethereum (ETH) is used for payments. Because transactions with higher fees are processed first, GAS fees may increase as the number of transactions increases.

9. Liquidity Mining (Liquidity Mining)

Considering the provision of liquidity (currency pairs), liquidity mining refers to the granting of governance tokens in addition to interest to attract those who implement yield checks and balances .

Examples of term usage

Liquidity mining is accelerating and profitable.

Details

In liquidity mining, by storing a specific asset in a liquidity pool and providing liquidity that traders can buy and sell, current swap fees can be earned as revenue. These liquidity mining originated from the largest decentralized exchange "Uniswap", and many liquidity mining contracts were born, such as Curve Finance and Balancer.

10. DeFi (Distributed Finance)

DeFi (Decentralized Finance) refers to financial services or systems that utilize blockchain and are provided without a central administrator.

Examples of term usage

Since June 2020, the DeFi market has developed rapidly.

Details

Abbreviation for "decentralized finance". Financial services provided by DeFi include issuing stable coins, lending currencies, and cryptocurrency exchanges. Many platforms use the Ethereum blockchain.

11. PoS (Proof of Stake)

PoS is a consensus algorithm that gives you the right to approve and generate new blocks based on the percentage (stake) of the virtual currency you own.

Examples of term usage

Ethereum co-founder Vitalik Buterin said that moving ETH’s consensus algorithm from PoW to PoS will improve security and scalability.

Details

Abbreviation for Proof of Stake. You can also consider the holding period of the virtual currency. It was born as an alternative to the “Proof-of-Work (PoW)” consensus algorithm, which requires high-performance computers to approve transactions and consumes large amounts of energy. If approved, you can receive newly issued virtual currency as a reward.

12. dApps

dApp is an application developed using open source blockchain.

Examples of term usage

South Korea’s largest Samsung Electronics app store “Galaxy Store” has started using Tron’s blockchain to process dApps.

Details

Abbreviation for "decentralized application", also known as "decentralized application" in Japanese. A major feature is that there is no centralized administrator. The most popular is the Ethereum blockchain, which is developing applications such as gaming and decentralized exchanges (DEX).

㈤ Blockchain treasure hunting has new tricks, everyone can win the treasure and everyone can be the villager

Following the mining crisis in June, a new trend has set off in the currency circle. Waves of treasure hunts. As a leader in the blockchain insurance industry, how could CIC miss a good publicity opportunity? Its partners have also developed the Raiders of the Lost Ark activity. It is said that not only can everyone participate in the treasure hunt, but everyone can also start the treasure hunt. , and the asset security guarantee is exclusively provided by Yunbao Chain CIC. Do you want to play it and experience the addiction of being a banker? Here is the detailed gameplay of Raiders of the Lost Ark. Let’s explore it together.

How to play Raiders of the Lost Ark:

This Raiders of the Lost Ark event, in which CIC exclusively provides asset security, is based on blockchain technology to automatically calculate the prize draw, ensuring fairness and justice and eliminating fraud. .

Treasure hunt features: Users can not only use digital currencies to participate in treasure hunts, but can also make their own bankers to initiate treasure hunts, with up to 33 participating currencies. Such as: CIC, ETH, AIDOC, QUN, DPY, LET, LRC, SEER, TRX, HIT, CMT, PST, IOST, MANA, BNB, NULS, THETA, PPT, GTC, AE, KEY, PAY, GTO, CVC, SOC, RUFF, EKT, CNMC, ELF, WIN, CAN, ABT, OMG.

1. Participate in the treasure hunt: Users use digital assets cic (or other currencies) to participate in the treasure hunt. Each time they participate in the treasure hunt, the system will assign a lucky number to the user based on the number of participations. After all the lucky numbers of the product are distributed, the blockchain treasure hunt program will calculate the lucky number based on the random number of the Ethereum block height. Users who hold the lucky number will obtain the product.

2. Initiate a treasure hunt: Not only can users participate in treasure hunts initiated by others, but they can also be their own banker and use their own coins to initiate a treasure hunt. After the lottery is drawn, the initiator can obtain the value of the prize. 5% as income.

3. The calculation rules are as follows:

1. When the exchange of all shares is completed, the system will record the latest block height of the current Ethereum.

2. Use the current block height + 12 as the height of the lottery block, and wait for the block with the lottery height to be generated, which takes about 3 minutes.

3. After the lottery block is generated, take the last four digits of the lottery height hash value (hexadecimal).

4. Then convert the four-digit hash value into a decimal number, and take the remainder + 1 from the total number of copies to generate this lucky number.

The above is the detailed gameplay of the Raiders of the Lost Ark activity where asset security is exclusively provided by Yunbao Chain CIC. It is common for everyone to win treasures, but this is the first time that everyone can be the banker. If you don’t want to experience it quickly, then join the CIC family quickly. You can search the Telegram channel obaoqibing to learn the details of the Raiders of the Lost Ark activity.

㈦ What is "Blockchain"

Blockchain is a public ledger and does not exist With centralized hardware or management institutions, anyone can automatically verify the authenticity of the ledger and easily discover whether the ledger has been tampered with by others.

In a word, the blockchain is a public ledger that can be verified by everyone.

The concept of being verifiable by everyone is crucial to blockchain.

Bitcoin uses the blockchain to record all transactions, so anyone knows the number of Bitcoins on each account.

So, as a publicly verifiable ledger, what are some use cases for blockchain?

In fact, there are many use cases that can be thought of. Blockchain is suitable for any data that can be recorded on a public ledger. Here are 4 examples:

1. Decentralized domain name server, namely domain currency. The domain name server is actually a ledger that records domain names.

2. Trustless public key encryption, such as https that discards unreliable certification authorities.

3. Ownership records, truthfully record the items and their corresponding owners.

4. Contracts and performance guarantees, the account book truthfully records the parties to the contract and saves the contract text.

But don’t forget that blockchain also has a very important component.

The ledger recorded using blockchain technology will always be updated. New data such as transactions, domain name inputs, records and contracts will be converted into hash values ​​of the same length by the hash algorithm and saved. However, hashing algorithms are not only not free but also very expensive.

Therefore, the ledger itself needs to have a recognition system to recognize the person who enters the block hash value.

In Bitcoin, this system is called mining and is rooted in the Bitcoin protocol. Bitcoin miners use a hash algorithm to convert transactions waiting for verification into hash values, and charge a certain amount of Bitcoin as a service fee.

Therefore, for non-monetary use cases, blockchain needs to find a way to bear the high cost of hashing algorithms.

I would like to remind everyone that my answer mainly focuses on the possible use cases of blockchain technology, and does not cover all aspects of blockchain, such as why hashing algorithms are so expensive. I believe you can definitely find a lot about Bitcoin and other blockchains onlineChain application details.

Supplement

Although blockchain technology has many advantages, there are still some less than ideal use cases. For example, there is no way to convert Bitcoin into any national currency; a ledger with billions of data entries would take up space and be impractical.

Bitcoin has shown the world that blockchain technology is feasible in principle, and people are also trying to solve these increasingly prominent problems, such as technological transformation of Bitcoin or the introduction of a completely Different blockchain technologies. I think the following two methods are worth trying: one is to split the ledger according to certain standards such as the payer address, and the other is to introduce a main blockchain to verify the sub-blockchain. Blockchain technology is ever-changing and dazzling, and it’s unknown whether someone is already making such an attempt. But Bitcoin is still the world's first currency blockchain, what others call a cryptocurrency.

Whether in the technology circle or the financial circle, blockchain has become the hottest word, no one. Blockchain has core advantages such as decentralization and trustlessness, and can perfectly solve problems such as information asymmetry, high transaction costs, and trust of strangers in the development of the sharing economy, making "individual economy" possible. Based on this, blockchain technology is considered to be the core technology that has the greatest potential to trigger the fifth wave of disruptive revolution after steam engines, electricity, information and Internet technology.

In this context, a blockchain craze was born in society, and everyone praised it overwhelmingly. Dialectics tells us that everything has flaws, and only by seeing the pros and cons of things can we make rational decisions. Therefore, in this article, Xue Hongyan (Hong Yanweiyu), a senior researcher at Suning Financial Research Institute, focuses on pouring some cold water on the blockchain.

| What is Blockchain

Blockchain, English Blockchain, has a rather mysterious technological flavor in its name, and can be simply broken down into "data blocks" and "links". Each data block contains all the information exchange data of the system within a certain period of time, and is encrypted using cryptographic methods; the link means that each block has a link relationship with the next block, thus forming a blockchain.

It is generally believed that blockchain has two major characteristics: decentralization and trustlessness. A brief introduction is as follows:

Since each block contains all the information exchange data of the system within a specific period of time, Therefore, each block is equal, and the damage of a single block does not affect the security of the entire system, so the blockchain has decentralized characteristics.

Similarly, since each block contains all the information of the system, the authenticity of the information can be cross-verified. Only by breaking through more than 51% of the nodes can the information be tampered with. In a large enough blockchain system , the cost is extremely high, it can be considered that the information in the blockchainThey are all real, so the blockchain has trustless characteristics.

Most people’s understanding of blockchain begins with Bitcoin. The relationship between the two is that blockchain is the underlying technology and concept, and Bitcoin is only the most popular application of blockchain at present. .

Maybe the above is not popular enough. Finally, let me summarize, what do you think the blockchain is? Is it a disruptive new technology? NO! According to Xue Hongyan (Hong Yanweiyu), a senior researcher at Suning Financial Research Institute, blockchain is not so much a new technology as it is a new ideological concept. The information encryption and other technologies included in the blockchain have been around for a long time, and it is more of a conceptual innovation. This is also the reason why the blockchain has a huge impact. New technologies will be surpassed sooner or later, ranging from one or two years to four to five years; only innovative ideas have enough energy to affect all aspects of the economy and society.

| Blockchain is expected to change the underlying rules of the financial system

In applications in the financial field, blockchain will change the transaction process and record keeping methods, thus significantly reducing transaction costs. It has significantly improved efficiency and is considered to have a broad market environment in digital currency, cross-border payment and clearing, bill trading, securities issuance and trading, property rights transactions, customer credit reporting, anti-fraud, and anti-money laundering.

Such a good technology is naturally sought after by everyone. Like many traditional financial people, Hong Yanweiyu resisted it at first, thinking that this thing was not that great, and did not do any research specifically. Later, as the research on financial technology gradually deepened, it was discovered that blockchain was an obstacle that could not be bypassed, because whether it was robo-advisory, big data risk control or online lending, they were only technological innovations at the financial business level and risk control level. It has not penetrated the bottom layer of the financial system. What is the underlying layer of the financial system? Naturally, it is payment and settlement, transaction rules and system interaction. What the blockchain changes is precisely the underlying rules.

Therefore, throughout the world, financial institutions are the most active in researching blockchain. If nothing else, they are really afraid. After the decentralization and trustless features of the blockchain are fully utilized, what else will the intermediaries of financial institutions do? It is estimated that this is also the first feeling of many people who have a preliminary understanding of blockchain.

In this article, Hong Yanweiyu focuses on pouring cold water on this view.

| Subverting the financial system, blockchain still faces two mountains

Marxist dialectics tells us that everything has two sides. The more prominent the advantages, the more obvious the flaws. It’s just the perspective. Just different. The two major problems with blockchain subverting the financial system lie precisely in the two major advantages of decentralization and trustlessness.

First, let’s talk about decentralization. First, we need to clarify a truth. Does centralization necessarily mean low efficiency? Of course not. Within a specific scope, the concentration of resources brought about by centralization can greatly improve efficiency. This is also the process of human evolution from individuals to villages.Reasons to tribe to nation. Take UnionPay as an example. UnionPay is the clearing and settlement center for the domestic banking industry. After UnionPay is established, each bank only needs to connect with UnionPay to realize transactions with all banks. If it is decentralized, without UnionPay, each bank will need to When communicating with all counterparties, which one is more efficient? Therefore, there is no need to beat centralization to death with a stick. The decentralization feature of blockchain is destined to only play a role in specific fields (that is, fields that are not suitable for centralization). How can it subvert everything?

Furthermore, it is a matter of trust. There is nothing wrong with detrusting itself, but the technical logic behind it is deeply flawed. Blockchain relies on universal accounting to achieve trustlessness, that is, all transaction information is retained in each block for system cross-verification to identify authenticity. Here comes the problem. Each block retains all transaction information. There is no problem on a small blockchain. However, as more and more information is added, it will inevitably lead to an explosive growth of transaction information and will also bring information. Dramatic increase in storage costs. At the same time, the greater the amount of information, the longer cross-validation takes and the lower the efficiency. Therefore, the blockchain solves the trust problem, but it brings about rising costs and declining efficiency.

Nothing in the world is perfect, and the same is true for blockchain.

As a conclusion, Hongyanweiyu wants to clarify that blockchain, as a conceptual innovation, does have great value and can also have a disruptive impact in specific fields. However, the current one-sided thinking about blockchain is problematic. Eastern wisdom tells us that "the most brilliant and the golden mean", in the face of anything, it is wisest to maintain the golden mean.

(Text/Xue Hongyan, senior researcher at Suning Financial Research Institute; WeChat public account: Hongyan Weiyu)

As early as a few years ago, the word "mining" came with Bitcoin is well known for its popularity. Many people know about Bitcoin first and then the blockchain, and they even don’t know about the blockchain yet. By definition, blockchain is a series of data blocks generated using cryptographic methods. Each data block contains information about a Bitcoin network transaction, which is used to verify the validity (anti-counterfeiting) and generation of its information. Next block.

I am not a computer technology expert. The following introduction to blockchain comes from reading and comments from expert friends and is for reference only.

If you want to use one word to explain blockchain, it is: distributed accounting.

To understand what this word means, you need to first understand that traditional accounting has a center. For example, in a bank, when you withdraw money from a bank deposit or lend money to others through the bank, the bank is the center, and all these transactions are based on the bank's credit. What if the bank cheats? Or is it more serious, is the country cheating? The Kuomintang's indiscriminate issuance of gold yuan notes at the end of its rule in mainland China, as well as the hyperinflation in Weimar Germany and Zimbabwe, which made the currency less valuable than toilet paper, are all very serious.Very famous example.

Golden Yuan Coupons

This is the problem that blockchain is aimed at. They believe that decentralized accounting is non-modifiable and non-repudiable. How to achieve decentralized accounting? The basic idea is that all users store all transaction records, making it very difficult to illegally modify the ledger through mathematical methods. In this way, the reliability of the ledger is guaranteed.

Specifically, all users exhaustively enumerate random number variables, and the first user to obtain a specific required hash function value (Hash) will have the right to record this round of transactions and obtain the corresponding Bitcoins award. It is transmitted in the form of data blocks, and the data blocks are connected into a chain by appending at the end, so it is called a block chain.

After listening to the introduction, you may feel that this idea is interesting, but it is not as exciting or revolutionary as advertised. Your feeling is right. In fact, the basic logic of blockchain has some unavoidable problems.

For example, the current size of the complete Bitcoin public ledger has exceeded 150 G, and is rapidly increasing at a rate of tens of G per year - just to support 5 million users and 30 million transactions per year. If its processing volume is one day comparable to that of Alipay, the size of the Bitcoin ledger will increase by more than 500 terabytes per year. This is equivalent to backing up the Alipay server's storage data on all users' personal computers. Do you think this is a good idea?

For another example, in the traditional banking system, if you lose your password, it is no big deal. Just report it to the system in time, and your wealth will not disappear. But in the blockchain system, if you lose your password, it will be a huge trouble, and your currency will not be recovered. Not happy? Is it surprising?

Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithms. The so-called consensus mechanism is a mathematical algorithm to establish trust and obtain rights and interests between different nodes in the blockchain system

In layman’s terms, it is to play mahjong. Four people can take turns to be the banker, and each other can shoot four people. They all have their own ledger records, but if you want to modify the ledger, you must have more than 50% of the modification rights, so the cost of cheating on the ledger is very high.

In the future, blockchain will be used more in finance to combat money laundering and fraud, because all information can be traced, and in culture it can be used for copyright protection, etc.

< /p>

I have seen a lot of people’s explanations of blockchain in official terms, and some may not even be clear to the person explaining it. I will explain blockchain in vernacular below to ensure that everyone can read it. Gotta understand.

What is blockchain? Let me give an analogy, in 50 yearsFinally, you can buy an electric fan from the supermarket. This electric fan will automatically mine coins for you when it is fanning. You can mine coins automatically while using the electric fan. When your electric fan breaks, you can Use the mined coins to repair the electric fan. Of course, you can also use the mined coins to purchase a new electric fan. Many people think wrongly! Wouldn’t the profits of merchants be less? Let me tell you about a certain brand. When the products of this brand are sold to you, the products themselves may even be sold to you at a loss. However, once the number of users becomes large and the users become more sticky, they can be paid through membership fees or service fees. Such small fees or other ways to make profits. Just like this, the mined coins can be purchased and repaired. Although the merchant's profit may be reduced, the merchant has gained more users and greater user stickiness. By this time, it only takes a minute for the merchant to make money.

And the electric fan you bought is equivalent to winding it up for you. What is winding up? If you put your electric fan on the street now, and 10 people come to snatch it, you have no way to prove that the ownership of this electric fan is yours. Once you put it on the chain, it is equivalent to being tied to you. Once it’s settled, you can prove it.

Therefore, the essence of blockchain is to help make people’s lives more convenient. It is equivalent to upgrading on the basis of the Internet, making it safer and more convenient. This is blockchain! It's that simple.

The security of the blockchain is reflected in its irreversibility and the data cannot be tampered with. We all know that in today's society, any data can be modified and conquered by hackers, but the data in the blockchain is impossible to change. Once generated, it cannot be modified unless all users in the blockchain work together. Agree to modify the data, but this is unlikely to happen.

At present, the blockchain is still very immature, just like the Internet bubble burst in 2000. When the bubble bursts, a truly valuable blockchain Internet will be hatched. company.

The wheel of history will not go backwards. Many people are unwilling to accept blockchain. Just like telling you that you can shop online 20 years ago, this is the same ridiculous thing. Time will eventually prove it. .

1. The main function of blockchain is to store information. Any information that needs to be saved can be written to the blockchain and read from it, so it is a database.

2. Anyone can set up a server, join the blockchain network and become a node. In the world of blockchain, there is no central node. Every node is equal and stores the entire database. You can write/read data to any node, because all nodes will eventually be synchronized to ensure that the blockchain is consistent.

3. EachEveryone works on the same blockchain, everyone publicly shares the current state of the blockchain, everyone agrees on the rules for new data submission, and tampering with the blockchain is computationally intractable.

If we assume that the database is a ledger, reading and writing the database is an accounting behavior:

Anyone can verify this public ledger, but there is no single The user can control it. Participants in the blockchain system will jointly maintain the update of the ledger: it can only be modified according to strict rules and consensus, and there is a very exquisite design behind this.

(1) Accounting, the system will find the person with the fastest and best accounting within a period of time, let this person do the accounting, and then broadcast the information on this page of the account book to everyone else on the entire network. node, which is equivalent to changing the database record; (consensus mechanism, cryptography)

(2) Verification, other valid nodes in the entire network check the correctness of the block accounting, and stamp the time Stamp to confirm that the block is legal; (timestamp, mathematics)

(3) Form a single chain, that is, compete for the next block after the previous legal block; (smart contract, encryption technology)

p>

(4) Storage, the account book is stored in blocks. As transactions increase, new data blocks will be appended to the existing chain to form a chain structure; (distributed structure, information technology) < /p>

(5) Backup, every participating trader is a node of the block network, and each node has a complete backup of the public account book, which is a distributed ledger.

Features

1. The blockchain has no administrator and is completely centerless. It is precisely because it cannot be managed that the blockchain cannot be controlled. Without an administrator, everyone can write data into it. In order to ensure the trustworthiness of the data: the technology of blockchain makes it impossible to tamper with the data once it is written.

2. Close to zero trust cost.

The cycle time required for Internet companies to build their credit is extremely long. For example, Taobao often takes several years to build its credit. In the blockchain, everyone trusts the code, algorithm and rules, so the cost of trust is extremely low.

3. The marginal cost of constructing and trading assets approaches zero.

If traditional assets are to be used for trading, they need to rely heavily on third parties, such as investment banks, banks, securities firms, etc., for packaging and endorsement, and the fees and thresholds are extremely high. With blockchain, these will not be a problem, and the cost is extremely low.

The value transfer attribute of the blockchain also naturally solves the payment problem, and has the genes to support global payments.

According to my current understanding

1. Blockchain is an outlet.

Everyone is talking about blockchain. Whether they have read it or not, whether they understand it or not, many people’s circles of friends are talking about it.For articles about blockchain, the only new WeChat group is the blockchain-related group.

Investors are talking, entrepreneurs are talking, almost every major Internet company is talking about it, government departments are taking a stand, and tens of thousands of vertical media focusing on blockchain are quickly born.

If you don’t join any currency circle or chain circle, you will be completely out. Even the well-known investment tycoon Zhu Xiaohu was unilaterally declared to belong to the old world by the rising star Chen Weixing.

2. Blockchain represents the story of sudden wealth.

Although ICO has been stopped by the national level, the most popular word-of-mouth about blockchain is still the increase in wealth by hundreds or thousands of times. Coins that were bought for a few cents or a few dollars are now worth dozens or hundreds of dollars. Everyone is talking about value-added stories.

There are Bitcoin and Ethereum. If you download a digital currency trading platform APP, the various currency codes composed of densely packed letters will feel like a stock exchange.

3. Blockchain is not only a technology, but also a belief at the conceptual level.

The basic layer, application layer, and a lot of blockchain knowledge seem to have a lot to do with the hot artificial intelligence.

Many people say that blockchain technology is mature, but applications have barely found an entrance. We can all shout loudly: Artificial Intelligence +, but if you shout "Blockchain +" now, it's not enough and you will be laughed at. The application scenarios are still being explored.

As for the previous Internet, it was an Internet of confidence. With the addition of blockchain, it became an Internet of value.

Such similar concepts are people’s good expectations for blockchain technology to solve the trust problem. If it is so easy to implement, blockchain can subvert finance, e-commerce, and many intermediaries. But why has the Internet not been subverted for so many years and real estate still relies on intermediaries?

4. Blockchain already has a history, so don’t think it is too new.

Just as many people claim that artificial intelligence is so new that it is a joke, its history can be traced back to the 1950s.

The blockchain is marked by the birth of Bitcoin, which was 10 years ago. There is also a still mysterious founder, Satoshi Nakamoto, who seems to have a Japanese name, and some say he is from the United States. From the Security Bureau, I think it can also be interpreted as "Chinese people are inherently smart", of course the latter is just a joke.

The reason why it has become so popular is because of the skyrocketing price of various digital currencies in 2017, which skyrocketed thousands of times in a few months and days. How could there be such an amazing speed in the past?

5. Blockchain is a knowledge system.

For me, whether it is a trend, whether it is a wealth game, or whether it is technology, we cannot ignore it or ignore it.

I started doing two columns, from peopleTo learn about the blockchain from the viewpoints of characters in the story, one is "Blockchain 100 People (Industry People)" and the other is "Blockchain 100 Investors (Views)" while learning and spreading.

As for related books, of course, I will accept them all as ordered. I can only be a follower of various trends and follow suit.

The biggest mistake is not how we criticize the blockchain, but to ignore it when we see it has a huge bubble and the crowd is enthusiastic about it. Stay away from it if you think you are noble.

The only way we have left is to be willing to be students, learn, and learn again.

Literal meaning: block, chain, using a chain to connect each block.

Blockchain = distributed data storage + point-to-point transmission + consensus mechanism + encryption algorithm

What is data storage? For example, a supermarket must have a ledger to record the entry and exit of various goods and transactions. This is storage.

What is distributed storage? It is the account book of this supermarket. Every employee has a copy. Every time there is something that needs to be recorded, it will be recorded in everyone's account book in a timely manner. Distributing each ledger (storage) to countless people (places) is distributed storage. (The supermarket employees here can be understood as blocks, and the ledger is the chain)

What is point-to-point transmission? In the same supermarket, there is no yogurt at the front desk. The shopping guide reports it to his superiors, and then reports it to his superiors.... Finally, he reports it to the warehouse. The warehouse records the accounting records in the ledger, and then transfers the goods to the front desk. As for point-to-point transmission, if there is no yogurt at the front desk, the shopping guide directly tells the warehouse, and the quantity sent by the warehouse to the shopping guide is recorded in the ledger. Everyone knows how many goods the warehouse has sent to the front desk. This is point-to-point transmission. There is no intermediate link, but the accounts can be made public for everyone who holds the ledger to see.

What is consensus mechanism? The consensus mechanism mainly includes two points. In a simple summary, the minority obeys the majority and everyone is equal. Similarly, the positions in this supermarket may be high or low, but everyone’s account books are indeed the same and equal. If someone makes a false account, then this person's account must be different from other people's accounts. At this time, it depends on whose account is remembered by more people. In theory, as long as the blockchain is large enough, then there is no need to make false accounts. Limit reduction! Because of the "minority obeys the majority" mechanism, if you want to make false accounts, then the number of false accounts you need to make must be at least greater than 50% of the total! On a network, if you need to change a piece of data, you must control at least 50% of the total number of computers to succeed.

The encryption algorithm is easy to understand. That is, when you go to the warehouse to adjust goods, the system will protect your privacy very well. It will only record the time, location, and person with a certain number who went to adjust the yogurt. It couldn't be the time, place, or Zhang San went to mix the yogurt. Taken together, this is the core component of the blockchain.

Personally, I think its main function is to decentralize and protect data that is difficult to tamper with! Decentralization and data protection are actually related. A supermarket only has one ledger, and any scheduling needs to go through the person who manages the ledger. If you need to make false accounts, you only need to control the person who manages the ledger. And if that supermarket uses blockchain technology, then he will make false accounts. If this is the case, you need to control more than 50% of the people who hold the total number of accounts of that supermarket. Obviously, controlling so many people will be almost impossible as the number of holders increases.

㈧ Super detailed compilation of blockchain and cryptocurrency industry terms (recommended collection)

Bitcoin Glossary: ​​Every blockchain and cryptocurrency phrase you need to know

p>

Despite the difficulties, blockchain technology has become mainstream. Bitcoin has become a household word, with financial institutions around the world investing in the cryptocurrency or allowing their clients to do so. At the same time, NFT has attracted the participation and appreciation of celebrities from all walks of life.

But despite this, blockchain technology remains very mysterious. Only talented engineers - many of whom were early adopters of cryptocurrencies like Bitcoin and Ethereum - can truly understand this, while it can still be difficult for laypeople.

Below is a glossary of blockchain terms you may find useful. (All phrases in alphabetical order)

Airdrop

An airdrop is when a company drops a cryptocurrency or NFT directly into your wallet. Instead of an IPO, the blockchain service will launch tokens and airdrop them to users who have used the service. There are several reasons for this: it could be pure marketing, as the airdrop raises awareness of the tokens people can invest in, or it could provide governance tokens for the DAO.

A recent example: the Ethereum Name Service allows users to change their wallet number to a wallet name (such as CNET.eth). Last December, it launched its own ENS token, airdropping a certain amount to everyone who uses the service. The more people use the Ethereum name service, the more tokens they get airdropped — worth tens of thousands of dollars in some cases.

Altcoin

Any cryptocurrency that is not Bitcoin or Ethereum is called an Altcoin. Sometimes called "shitcoins."

Binance

The world's largest cryptocurrency exchange, where people buy and trade cryptocurrencies. It is under investigation by the U.S. Department of Justice and the Internal Revenue Service for tax evasion and money laundering.

Blockchain is a "distributed database". Simply put, it is a decentralized ledger that records information in digital “blocks.” Once a block is mined and added to the chain, it cannot be changed, so the blockchain provides a public record of unchangeable data.

There are many different blockchains with varying degrees of decentralization, efficiency, and security. Many people have their own cryptocurrencies - for example, Ethereum is a cryptocurrency built on the Ethereum blockchain.

Bitcoin

Bitcoin is the first cryptocurrency, built on the Bitcoin blockchain. It was created in 2009 by a person or group of people under the pseudonym Satoshi Nakamoto. Only 21 million pieces can be minted, of which approximately 18.9 million are already in circulation.

Burning

Cryptocurrency is "burned" by sending to a wallet that can only receive but not send. Burning mechanisms are often used to create a deflationary effect: the fewer tokens in circulation, the scarcer the tokens held by investors.

Buy the dip

This refers to buying more of an asset after its price has fallen. For example, if the price drops by $10,000, a Bitcoin holder might “buy the dip.”

Cold Wallet

A cryptocurrency wallet that is not connected to the Internet. These wallets are safer and less susceptible to scams.

Cross-chain

The ability to send data, tokens or assets from one blockchain to another. This is different from “multi-chain” services that are built to work on multiple blockchains.

Cryptography

A form of information encryption in which data can only be decrypted using a key. Blockchains using a proof-of-work protocol rely on solving extremely complex cryptographic puzzles in order to mine and verify new blocks.

Cryptocurrency

Cryptocurrency is a token native to the blockchain. Cryptocurrencies are typically minted with each new block mined. For example, every time a new Ethereum block is mined, two Ether coins will be obtained as compensation for the miners.

A cryptocurrency is a token. Their birth is their defining factor: other tokens are created using platforms and applications built on top of the blockchain, while cryptocurrencies are built into the blockchain’s protocol.

Decentralized Applications (Dapps)

Abbreviation for Decentralized Applications.

Dao (DAO)

A decentralized autonomous organization. The DAO is an organization that makes decisions through consensus: all holders of governance tokens receive voting rights in organizational decisions, and the solution with the most votes is the DAO's action plan. Imagine a decentralized investment bank, but instead of fund managers making investment decisions, holders of their governance tokens vote on how to invest the funds in their treasury.

Decentralized exchange

Decentralized exchanges are used to buy and trade cryptocurrencies. Unlike typical exchanges, these exchanges use peer-to-peer trading that bypasses any centralized authority. These include Uniswap and Sushiswap.

Decentralized Finance (DeFi)

Abbreviation of "decentralized finance". DeFi is any financial instrument that uses blockchain technology to bypass centralized institutions, such as smart contracts or DAOs.

Diamond Hands

A diamond hand is a person who holds financial assets for the long term or during periods of price volatility.

DYOR

Abbreviation for "Do Your Own Research".

Ethereum (ETH)

A cryptocurrency mined on the Ethereum blockchain. Ethereum has a market capitalization second only to Bitcoin, but is a more commonly used cryptocurrency. Most altcoins are also built on Ethereum and are therefore pegged to Ethereum. Most NFTs are also built on Ethereum, which is why Ether is the primary token used in NFT transactions.

Ethereum

A blockchain that competes with Bitcoin. It aims to take the blockchain technology pioneered by Bitcoin developers and use it for more complex financial instruments such as smart contracts.

Flash loan (FFlash loan)

Flash loan is a DeFi tool that allows loans to be made without collateral. Flash loans allow you to borrow money to buy an asset, but only if you can buy the asset and repay the interest within the same block. Imagine using a loan to purchase a $1 million house, but the loan will only be approved if you have lined up another buyer who is willing to pay enough for you to repay the loan plus interest.

These loans use smart contract technology.

FUD

Abbreviation for "fear, uncertainty and doubt". This could be legitimate, such as people expressing concerns about the safety or legality or safety of a token or NFT project, such as an organized move to encourage people to sell, lowering the price of an asset.

Gas

Gas is the price you pay to use the Ethereum network. Each transaction requires a gas fee, which depends on how overloaded the blockchain is. Prices typically range from $50 to $500 per transaction, but prices can spike when the network is under heavy load.

Governance token

Governance tokens are cryptocurrencies that give their owners voting rights on a given project. See also: DAO.

GWEI

The cost of gas is expressed in GWEI. As a rough guide, when gwei is below 50, gas will be cheap, and when gwei is above 100, gas will be expensive.

HODL

An intentional misspelling of "hold" used to encourage people to hold their coins during price drops.

Layer 1 and Layer 2

If you dabble in cryptocurrency, you will have heard of Layer 1 and Layer 2 solutions. Layer 1 is the blockchain architecture itself, while Layer 2 refers to the architecture built on top of the blockchain.

For example, take the high gas cost problem of Ethereum as an example. Layer 1 solutions are to make the Ethereum blockchain more efficient, for example by adopting a proof-of-stake protocol. An example of a Layer 2 solution is Immutible X, an exchange built on Ethereum that uses smart contract technology to allow gas-free, carbon-neutral trading.

Liquid Market (Liquid Market)

A liquid market is a market with a large number of buyers and sellers, which allows buy and sell orders to be completed almost immediately. Cryptocurrency markets are liquid, NFT markets are not. Most legal cryptocurrencies can be bought and sold at any time, as NFT traders are required to list items for sale in the hope that buyers will purchase them manually.

Mainnet

A blockchain protocol for public use will be put into the mainnet. This distinguishes it from a testnet, which is more like a beta release of a blockchain protocol.

Memecoins

Many cryptocurrencies are designed to provide utility or services. Memecoins offer no practical prospects and exist purely as speculative assets. Dogecoin is the most well-known, but there are many, many more.

MetaMask

A browser-based online digital wallet, mainly used on the Ethereum blockchain transaction.

Mining

Mining is the process of verifying transactions and adding blocks to the blockchain. This usually involves powerful computers solving complex password problems. Crucially, this is also how new cryptocurrencies are added into circulation.

Mining Rig

A powerful computer set up for the specific purpose of mining cryptocurrency.

Mining Farm

A warehouse (or room) of mining equipment that operates around the clock and is used to mine cryptocurrency.

Mint

On the blockchain, minting means verifying information and making it a block on the blockchain.

To "mint" an NFT means to purchase it from its creator during a public sale. The "mint price" is the price at which its creator sells it - for example the "mint price" of Bored Ape Yacht Club is 0.08 Ether. After all NFTs in a collection have been minted, traders who want exposure to the collection need to purchase them from a secondary market like OpenSea.

Multi-chain

Applications or services designed to work with multiple blockchains. This is related toUnlike cross-chain applications and services, cross-chain applications and services are designed to send data or assets from one blockchain to another.

MOON

A sharp surge in price is called "mooning" or "a moon". "To the moon" is a common phrase.

NFT

Non-fungible token. These are digital contracts that prove ownership of digital assets. Currently, they are associated with art, but NFTs can prove ownership of any number.

Off-Chain/On-chain

On-chain refers to things that exist on the blockchain, and off-chain refers to things that exist on the blockchain something other than something. Cryptocurrencies are on-chain currencies, and fiat currencies are off-chain currencies.

OpenSea

It is the largest NFT marketplace, specializing in Ethereum-based NFTs. (NFTs built on different blockchains are often sold on specialized marketplaces. For example, Solana NFTs are sold on Solanat.)

Play to Earn (P2E)

Play to Earn (P2E) games integrate blockchain and reward players with in-game cryptocurrency. Cryptocurrencies in these games can be exchanged for Bitcoin or Ethereum. The most prominent example is Axie Infinity, where players can earn Smooth Love Potion ($SLP).

Proof of Work

Proof of Work (POW) is a consensus mechanism by which blocks are added to the blockchain. Proof-of-work requires miners to solve complex cryptographic puzzles, which require large amounts of energy from powerful mining equipment, in order to verify new blockchain transactions.

Proof-of-work is a secure and decentralized consensus mechanism, but it is notoriously inefficient. This is how the Bitcoin and Ethereum blockchains work, although Ethereum will soon move to a more efficient Proof of Stake.

Proof of Stake

Faced with the huge energy demand of proof of work, Proof of Stake (POS) is a newer consensus machinesystem to mine blocks more efficiently. Proof of Stake allows cryptocurrency holders to validate new blocks on the relevant blockchain.

They do this by staking their cryptocurrency. Network users stake their cryptocurrency, and if their stake is selected via a random algorithm, they have the opportunity to validate a new block – for which they are rewarded in the form of more cryptocurrency. The more cryptocurrencies are staked, the greater the chance that users will be selected to validate new blocks.

Proof-of-work rewards those who expend the most computing power to solve cryptographic puzzles, while proof-of-stake rewards those who have invested in the cryptocurrency for the long term.

Pump and dump (Pump and mp)

Pump and dump schemes involve artificial incentives for a product, causing people to buy it and raising its price. The pump-and-dump coordinators then sell their assets at inflated prices, causing prices to fall sharply.

These exist in traditional markets but are more common in cryptocurrency trading because the low liquidity of micro-cap cryptocurrencies makes their prices easier to manipulate.

Rug pull

A rug pull is when the creator of a cryptocurrency disappears, taking the funds with them. A recent example is the counterfeit Squid Game coins, although these coins are far from rare. “Carpet” is essentially shorthand for “scam.”

Satoshi Nakamoto

A pseudonym for the creator of Bitcoin. The white paper explaining the need for decentralized finance and explaining how Bitcoin works was signed by Satoshi Nakamoto, but no one knows who the real person was. It is speculated that Satoshi Nakamoto was actually several people.

Seed Phrase

When you create a cryptocurrency wallet, you are given a 12-word seed phrase . Every time you log into your wallet on a new device, you will need to use a mnemonic phrase. Never give your mnemonic phrase to anyone.

Sharding

Sharding distributes the network load on the blockchain, allowing more transactions to be processed per second. This sounds boring, but it's very important. Ethereum will integrate sharding next year, which will make using it cheaper and less damaging to the environment.

Shitcoin

Shitcoin is an altcoin that provides no utility, be it memecoin is still an invalid altcoin.

Silk Road

Silk Road was an online black market that was shut down by the FBI in 2013. This is where many people are first exposed to cryptocurrency, as Bitcoin is a popular payment method for illegal goods on the site.

Smart contract

A smart contract is a digital contract that executes itself when required conditions are met. For example, if Wallet X sends 0.08 ether to Wallet Y, Wallet Y sends NFT Z to Wallet X. They are most commonly used for automated trading, but can also be used for more complex purposes, such as quick loans.

Stable coin

Stablecoin is a cryptocurrency pegged to the US dollar. These include Tether and USDC. Their purpose is to allow cryptocurrency traders to keep their coins within the crypto ecosystem without experiencing the volatility of Bitcoin and Ethereum price fluctuations.

Staking

Equity staking is to lock the funds held in the cryptocurrency wallet to support the operation of the blockchain network. Essentially, it involves locking up cryptocurrency to earn rewards. In most cases, the process requires users to participate in blockchain activities using a personal crypto wallet.

The concept of equity staking is closely related to the Proof of Stake (PoS) mechanism. It is used in many other blockchain systems based on PoS or similar.

TLT

Abbreviation for "think long term".

Token

Tokens are various forms of blockchain assets. A cryptocurrency like Bitcoin is a type of token. Other types include governance tokens , which grant holders voting rights in a DAO or service, or utility tokens , which grant access to services based on the number of tokens held.

TXN

Abbreviation for transaction.

Utility Token

A token designed to provide a certain function. These can be access to applications, services or games. Examples include Filecoin, which grants access toAccess to blockchain-based digital storage, and Link, which connects smart contracts for off-chain type data.

Vanity Address

Personalized wallet addresses provided by companies such as Ethereum Name Service. It allows you to change your wallet address to a word or phrase of your choice, such as CNET.eth.

Vaporware

Products that were promised but never actually made it to market. The term became popular in the late 1990s with the original dot-com boom and has seen a revival thanks to shady cryptocurrency creators.

Vitalik Buterin

The creator behind the Ethereum blockchain.

Wallet

A cryptocurrency wallet is a place where you can store cryptocurrencies and NFTs. These wallets can be hot or cold wallets – i.e. browser wallets connected to the internet or physical hardware not connected to the internet. Wallets are read-write, which means they can receive information as well as signatures or online IDs.

Web 3

Web3 is the next iteration of the Internet imagined by blockchain enthusiasts. From the invention of the Internet until around 2005, Web1 was the read-only Internet. Web2 refers to the emergence of users being able to produce content and upload it to the Internet. Web3 will be an Internet integrated with blockchain. Imagine owning your social media posts as NFTs, using a cryptocurrency like Ethereum as a universal currency, and having your wallet as a form of ID rather than an email/password combination.

Whale

A person who holds a large amount of cryptocurrency.

Whitelist

Pre-sale list of cryptocurrencies and NFTs. Whitelisted investors can purchase assets ahead of a public offering, sometimes at a discount.

WAGMI

Abbreviation for "we're all going to make it".
