⑴ What is blockchain

In the simplest terms, blockchain is a distributed ledger.

To understand what this means, we first have to look at its opposite: a centralized ledger. Because blockchain technology started with finance, we will also introduce it below using banks as an example.

The following is our process for using bank debit card transactions:

You can swipe your card to purchase goods in stores.

The merchant sends a statement to your bank for the agreed upon amount.

Your bank will verify that you may have authorized the purchase.

The bank sends the money to the merchant.

Finally, the bank records this information in its ledger.

There’s a lot of technology involved here, but that’s basically it. The last step is important - the bank records all transactions made by the customer. This ledger goes all the way back to the first transaction the bank made.

This ledger is kept, maintained and regulated by the bank. You can read it in your online bank account, but you can't change it. The bank has complete control. If it decides to make a change, there's nothing you can do about it.

Crucially, if hackers were able to access a bank’s ledger, that could cause a lot of problems. They can change the account balance to make it look like certain transactions never occurred, etc.

This is why distributed ledgers are so cool.

Blockchain Network Visualization

If a bank operates on a distributed ledger, each member of the bank will have a copy of the ledger, and whenever any member of the bank When they make a purchase, they tell every other member of the bank.

Each member will validate the transaction and add it to the ledger (the added records are called "blocks"). This has some important benefits, as there is no centralized authority that can manipulate records. Hackers accessing one ledger won't be a big problem because other ledgers can easily verify it.

On the other hand, it requires a lot of work. In short, the second system is blockchain (at least in financial scenarios).

As mentioned above, blockchain is a decentralized list of transactions. If I send Xiao Ming 2 Bitcoins, I send a message to everyone in the network saying "I am sending Xiao Ming 2 Bitcoins" and they all record the transaction.

The future of blockchain, how will it change our lives?

One thing that is important about blockchain is that it is a public resource and no one really owns it because everyone owns it.

Blockchain is not just science fiction. We don't need to careUnderstand the mechanisms behind this technology, but you need to understand that it may completely change our lives in the next 20 years.

This may sound bold, but remember, 20 years ago we were browsing the Internet on Netscape, using state-of-the-art Motorola flip phones, and buying our first DVD players. At that time, if we imagined that a computer could be held in our hands and that we could buy cars, make payments, and watch movies, it would have been considered a fantasy.

Although the impact of blockchain may not be as obvious as the Internet, nor as tangible as mobile phones, blockchain will effectively solve many worries in daily life. Such as intermediaries cheating people, transaction delays, etc. In our current lives, middlemen are everywhere and we take them for granted as a part of life. If one day these intermediaries cease to exist, you will find that the world will become a different place.

Imagine that by 2040, blockchain may become a mature and widely used technology. When one day you can't live without the blockchain just like you can't live without the Internet now, you will be surprised to find that this decentralized accounting technology has simplified the complexity and become a part of your lifestyle

⑵ What is the ERC20 Token Standard in the blockchain?

RC20 Token Standard (ERC20 Token Standard) is a specification for creating tokens through Ethereum. According to the ERC20 specification, a smart contract can be written to create an "interchangeable token". It is not mandatory, but by following this standard, the tokens created can interact with numerous exchanges, wallets, etc., and it is now generally accepted by the industry.

The ERC20 token standard was first proposed by Ethereum developer Fabian Vogelsteler in the open source community. Later, Ethereum founder Vitalik (known as "V God") wrote the first The first version of the document was called "Standardized_Contract_APIs" at the time.

Smart contracts can be written following the ERC20 token standard. The token methods it needs to implement include: optional name, symbol, decimals, and required balanceOf, transfer, transferFrom, approve, and allowance. The event responses it needs to implement include Transfer and Approve

In addition to ERC20, the most popular token standards in Ethereum are ERC721. Unlike ERC20, ERC721 is a non-fungible token standard (NFT).

ERC20 tokens are fungible and homogeneous, while ERC721 tokens are non-fungible and non-fungible.; ERC20 tokens can be infinitely divided and subdivided, while the minimum unit of ERC721 tokens is 1 and cannot be divided and subdivided.

In June 2018, ERC721 was finally officially accepted by the Ethereum community and became the final standard. The previously popular cryptokitties followed the ERC721 standard.

The Xueshuo Innovation Blockchain Technology Workstation under Lianqiao Education Online is the only "blockchain technology" approved by the "Smart Learning Workshop 2020- Xueshuo Innovation Workstation" carried out by the School Planning and Construction Development Center of the Ministry of Education of China. Professional” pilot workstation. The professional position is based on providing students with diversified growth paths, promoting the reform of the training model integrating professional degree research, production, and research, and building an applied and compound talent training system.

⑶ Easy to understand What is blockchain

Bitcoin began in 2008 with the paper of the mysterious Satoshi Nakamoto. In the 13 years since its birth, Bitcoin has experienced countless market tests and technical attacks, but it has always stood firm.

Now Bitcoin has grown into a currency system with millions of users around the world, tens of thousands of merchants accepting payments, and a market value of up to tens of billions of dollars.

In layman's terms, a Bitcoin user runs the Bitcoin client software, and such a computer is called a node. A large number of node computers are connected to each other to form a P2P (peer-to-peer) network.

The specific principle can be understood like this:

For example, A has 10 Bitcoins and wants to transfer 1 to B, and B’s original account The balance is 2 Bitcoins.

• A first broadcasts the transfer transaction request to surrounding nodes: "Attention everyone, I am A, and I want to transfer 1 Bitcoin to B. This broadcast is true and signed with my private key. "

• Nodes around A receive A's broadcast, first check the authenticity of the transaction signature of A's account, and then check whether A's account has sufficient balance.

• After checking and confirming that there is no problem, the node starts to make a note on its own account book: Account A transfers 1 Bitcoin to Account B, and modifies the account balances of A and B: Account A balance = 10 Bitcoin - 1 Bitcoin = 9 Bitcoins, account B balance = 2 Bitcoins + 1 Bitcoin = 3 Bitcoins.

• After the node has finished recording, it broadcasts the transaction to the surrounding node brothers, spreading it from ten to ten until all nodes receive the transaction. The transaction between A and B was recognized by the entire network.

⑷ What is the popular explanation of blockchain

What is the popular explanation of blockchain

What is the popular explanation of blockchain? Blockchain is currently a hot topic topic, inThe domestic development speed is also getting faster and faster, but many people still don’t know what blockchain is? Now I will give you an easy-to-understand explanation of what blockchain is!

Popular explanation of what blockchain is 1

Generally speaking, blockchain is a decentralized distributed ledger database. The advantage of this distributed ledger is that buyers and sellers can trade directly. There is no need for any intermediary, everyone has a backup, even if your copy is lost, it will not be affected.

Suppose you have a ledger at home, and your parents give you your salary and ask you to record it in the ledger. You misappropriated more than ten yuan privately because of your greed, and no one else knew about it. But the way to solve the problem with blockchain is to keep accounts with the whole family. Not only you are keeping accounts, but your father, mother, brother, sister, younger brother, sister, etc. are all keeping accounts. They can all see the general ledger, and you It cannot be changed, and neither can others.

Blockchain is a new application model of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. Blockchain technology has been widely used in different industries. Such as product traceability, copyright protection and transactions, payment and settlement, Internet of Things, digital marketing, medical care, etc.

Common questions in blockchain engineer interviews

What do you think the block in blockchain technology means?

The blockchain consists of information about all financial transactions. A block is nothing more than a list of records. When these lists are combined together, they are called a blockchain. For example, if an organization has 100 ledgers, their combination is called a blockchain, and a single ledger will be considered a single block.

Why is blockchain a trustworthy approach?

There are many reasons to trust blockchain. The first reason is that it is compatible with other business applications because it is open source. Secondly, it is secure because it was developed for online transactions, so the developers pay special attention to its data synchronization while keeping it safe. Because the type of business it holds is unrelated, it is easy to consider distinguishing chains when choosing.

How much do you know about blockchain?

This is a technology that was actually designed for Bitcoin and later heavily promoted for the multiple benefits of monitoring and recording all financial transactions on the network. This is a trusted method that is currently being used by many organizations. Since everything is secure and open source, it is easy to gain trust in the long run.

Utilizing blockchain in an organization, if there are specific technical requirements for that network?

No specific conditions of use. However, the network must be a peer-to-peer network under the relevant protocol. It literally just validates new blocks and helps organizations stay in sync without having to invest in third-party applications.

What is encryption? What is its role in blockchain?

Data security is always very important. Encryption is basically a way to help organizations keep their data secure. In this technique, data is encoded or altered to some extent by the sender before being sent to the network. Only the receiver can know how to decode it. This practice is very useful in blockchain because it increases the overall security and authenticity of the block and helps ensure that the block is secure.

What types of records can be saved on the blockchain? Are there any restrictions?

There are no restrictions on any type of records in the blockchain approach. Currently, many organizations around the world are using this approach, and the fact is that medical transaction records, organization-related events, administrative activities, transaction processing, identity management, document records are all common record types that can use blockchain. And record keeping is not limited to these applications..

What is double spending?

This is one of the main issues related to digital currencies. In practice, this is a condition of passing a digital certificate, since the card can be used multiple times through a digital file that is often easily cloned. It only leads to inflation and the organization has to bear huge losses. A major technical goal of blockchain is to eliminate this approach as much as possible.

Explain the importance of blind signatures and how they are useful?

It is actually a form of digital signature, an important part of cryptography, where all information is blinded until it is actually considered or signed. This is a proven method often considered in different privacy-related agreements between the author and the signatory. Digital currency design is one of the most common examples.

What is key sharing? Are there any benefits to blockchain technology?

As we all know, security issues in digital transactions are very important. Key sharing is a similar approach. In blockchain technology, this is a method of dividing keys or personal information into different units and sending them to network users. The original information can only be merged if the participant who distributed the key agrees to be merged with other participants. It can provide various security-related benefits in blockchain technology.

What organizations can use blockchain technology?

This method can be considered as commercial class without strict upper limit. In fact, almost all businesses are doing or online financial transactions that require them to successfully complete the implementation process. Large enterprises, financial institutions, private enterprises, government departments, and even defense agencies can easily trust this technology.

What is the difference between a blockchain ledger and a general ledger?

First of all, the main difference is that blockchain is a digital ledger that can be easily decentralized. This method is much less likely to go wrong than a regular ledger. Normal books are written by hand or by hand, blockchain does all the tasks automatically. You just need to configure it the right way and follow all the guidelines.

What is a soft fork?

Blocks in the ledger are included in a way that builds the longest chain, i.e. the chain with the greatest cumulative difficulty. A fork is a situation where there are two candidate blocks competing to form the longest blockchain, and two miners discover a working problem and fail to synchronize with each other within a short period of time. Causes network fragmentation because some nodes get blocks from miner #1 and others get blocks from miner #2. Forks are usually resolved in one block because the probability of this happening again becomes very low as the next block comes out so soon there is a new longest chain that will be considered primary.

⑸ The top 20 blockchain projects were unveiled at the Hi-Tech Fair and achieved remarkable results in technological and industrial innovation and development

From November 11th to 15th, the 22nd China International High-tech Achievements Trade The China Hi-Tech Fair (hereinafter referred to as the "High-Tech Fair") was officially held at the Shenzhen Convention and Exhibition Center, with a total exhibition area of ​​more than 140,000 square meters, more than 3,300 domestic and foreign exhibitors, nearly 10,000 projects participating in the exhibition, and more than 140 various activities.

⑹ What is blockchain

From the perspective of science and technology, blockchain technology involves many scientific and technological issues such as mathematics courses, cryptographic algorithms, big data technology and computer programming. From an application perspective, to put it simply, blockchain is a resource sharing ledger and database of a distributed framework, which has the characteristics of decentralization, inability to forge, traces of the entire process, traceability, collective maintenance, openness and transparency.

Based on this characteristic, blockchain technology establishes a reliable "trust" foundation and creates a reliable "collaboration" system, which has broad value. In recent years, the world's attitude towards Bitcoin has been ups and downs, but blockchain technology, as one of the basic technologies of Bitcoin, has received more and more attention. In the Bitcoin generation process, a block is a storage unit that records all information exchanges of each block node within the corresponding time period. The intermediate links between each block are achieved according to random distribution (also known as hash algorithm), and the subsequent block contains the hash value of the subsequent block. As the exchange of information expanded, 1 block and 1 block continued, and the result became known as blockchain technology.

Blockchain technology, as an auxiliary technology, does not decentralize the entire energy network, but makes the energy network more closely connected. Each network can be "autonomous" while maintaining independence. This independence can While improving the work efficiency of each outlet, it can also reduce the work efficiency of each outlet and avoid the energy loss of "intermediate links".

1. What is ERC20

ERC20 is a token standard on the Ethereum blockchain. It is a digital currency that can be used for transactions, payments, investments and other purposes. ERC20 is a standard based on smart contracts. It is widely used in crowdfunding of blockchain projects and is a standard for Ethereum tokens. ERC20 tokens are generated through Ethereum smart contracts, and they can be transferred, paid, and traded on the Ethereum blockchain.

2. Characteristics of ERC20

ERC20 tokens have many unique characteristics, the most important of which are programmability, tradability, traceability and auditability . It can be programmed for more functionality, can conduct transactions on the Ethereum blockchain, can track the movement of tokens, and can be audited to ensure the safety of funds.

3. Advantages of ERC20

The advantage of ERC20 token is that it can support crowdfunding projects on the Ethereum blockchain, and these crowdfunding projects can use ERC20 Tokens for financing. Transactions for ERC20 tokens are also fast and can be completed within seconds. Additionally, transaction costs for ERC20 tokens are also very low, with Bitcoin’s transaction costs being much lower.

4. Disadvantages of ERC20

The disadvantage of ERC20 tokens is that it cannot support cross-chain transactions and therefore can only be traded on the Ethereum blockchain. Additionally, ERC20 tokens cannot be used for investments as they cannot support investment activities.

5. Applications of ERC20

ERC20 is aIt is a token standard that has the characteristics of programmability, tradability, traceability and auditability. It can be used for crowdfunding, payment, investment, trading and other purposes, and has good development prospects.

⑻ A brief introduction to ERC-20

ERC-20 is a technical standard for issuance and implementation of tokens on the Ethereum blockchain. It was proposed by Ethereum developer Fabian Vogelsteller in November 2015. The standard describes a set of general rules that tokens should follow in order to function properly within the Ethereum ecosystem. Therefore, ERC-20 should not be considered a piece of code or software. Instead, it can be described as a technical guide or specification.

The ERC-20 standard makes it easier for developers to more accurately predict interactions between different tokens and applications. It also defines how ERC-20 tokens are transferred within the Ethereum blockchain and how their respective supply and address balances are consistently recorded.

In other words, ERC-20 provides developers with a list of rules to follow in order to operate seamlessly within the larger Ethereum platform. Many decentralized applications (DApps) and services support ERC-20 tokens, making it easier for community members and businesses to adopt and use them across a wide range of applications such as cryptocurrency wallets, decentralized exchanges, games, and more .

There are multiple ERC20 compliant tokens deployed on the Ethereum blockchain, but with unique and unique implementations. Depending on the method, tokens can be used to represent various digital assets or tradable goods (such as coins, vouchers, gold certificates, loyalty points and IOUs). Additionally, ERC-20 tokens can be used as a means to tokenize voting rights during elections.

The ERC-20 standard significantly reduces the amount of work required to create and issue digital tokens, which may be related to the increased interest in ICO crowdfunding campaigns and blockchain technology as a whole. Several projects are already using the technical standard, and the number of ERC-20 token contracts has grown dramatically over the past few years. In mid-2017, there were approximately 5,500 ERC-20 smart contracts on the Ethereum network. In early 2018, that number grew to more than 40,000 and now exceeds 160,000.

Although most tokens on the Ethereum network follow the ERC-20 standard, there are some exceptions. For example, Ether (ETH) was created before the standard but has not yet adhered to it. This led to the creation of the so-called Wrapped Ether (WETH) - an ERC-20 token that represents Ether at a 1:1 ratio (1 WETH = 1 ETH).WETH allows users to trade their ETH with other ERC-20 tokens on decentralized exchanges.

Technically, the ERC-20 standard describes six functions that maintain some of the functionality and characteristics of Ethereum-based digital tokens. These features include the way tokens are transferred between addresses and some important data related to the token smart contract, such as symbol, name, and supply.

This is the Rabbit community, everyone is welcome to pay attention, we will continue to share high-quality currency circle content! Popularize blockchain knowledge!

⑼ What does it mean to choose ERC20 to withdraw coins?

To choose ERC20 to withdraw coins means that the user selects the ERC20 protocol when withdrawing coins. Then accordingly, when filling in the withdrawal address, you must write based on Ethereum address for the ERC20 protocol. The withdrawal speed of the ERC20 protocol is relatively fast, and the fee type paid is ETH. Most trading venues support deposits and withdrawals. The withdrawal limit is low. It supports smart contracts and makes on-chain transaction inquiries more convenient. The security and transfer speed of ERC20-USDT are acceptable, and it is suitable for frequent transactions in the digital currency market. If users often do short-term transactions, it is recommended to choose ERC20-USDT first.
Extended information: 1. When depositing and withdrawing USDT, investors find that there are three different chain types to choose from, namely ERC20, TRC20 and Omni, and most investors are stuck here. Among the three I don’t know how to choose between them, or even understand what these three are. To put it simply, ERC20 is the chain type of the Ethereum blockchain, TRC20 is the chain type of the Tron blockchain, and Omni is the Bitcoin block The chain type of the chain network.
2. In 2014, USDT was born on the Bitcoin network and was officially launched on several major exchanges in February 2015. Before 2018, there was only one transfer path for USDT, and that was Omni-USDT based on the Bitcoin network. Omni-USDT is stored on a Bitcoin address, so every time you transfer, you need to pay Bitcoin as a miner fee. Omni-USDT is on the Bitcoin network chain, and the cost of hacking is very high, so the asset is relatively secure. However, its transaction speed is very slow and cannot meet the needs of today's encryption trading market. However, many large transactions will still tend to Omni-USDT. ERC20-USDT is average in terms of security and transfer speed. Suitable for frequent transactions in the digital currency market. If you often do short-term transactions, you can choose ERC20-USDT first.
3. In 2018, the Ethereum network became popular, and blockchain applications were also widely used, and ERC20-USDT appeared. Like Omni-USDT, using ERC20-USDT also requires payment of absenteeism fees, but the transfer speed has been significantly improved. Due to its good security and fast transfer speed, ERC20-USDT isThe market has widely accepted it, and TEDA, the issuer of USDT, has also begun to support the more efficient Ethereum ERC20. Because the comprehensive index is relatively high, it is more popular on mainstream trading platforms.
