㈠ Which blockchain projects are worth investing in now?

Nowadays, blockchain has been vilified by many players. When it comes to blockchain, the first reaction of many people is that they are scammers. In fact, blockchain has now begun to study practical applications in many industries, such as logistics, medical care, etc. If you invest, you can start with application implementation, but the cost is too high and the technical requirements are relatively high. The other is mining. Although the income will be slower, it is still relatively stable. Don't believe in all kinds of stocks with high profits and high returns. The greater the temptation, the deeper the pit.

㈡ How to explain blockchain in a popular way

“Blockchain technology is considered to be the next generation of disruptive core technology after steam engines, electricity, and the Internet. If the steam engine unleashes People's productivity, electricity solves people's basic living needs, and the Internet has completely changed the way information is transmitted. Then the blockchain, as a machine that builds trust, will likely completely change the way value is transmitted in the entire human society."

I have just come into contact with the blockchain. There are too many basic knowledge that need to be understood and known. Don’t worry, today I will popularize this knowledge for you. Today, let’s first take a look at what public chains, private chains, alliance chains, and side chains are.

㈢ What is blockchain and how should ordinary people invest in blockchain projects?

Blockchain is a distributed technology. Specifically, it can As for the technology under the Internet, ordinary people can currently invest in two directions. One is to invest in the stocks of blockchain companies. This has certain risks. Individuals can follow what they are familiar with. The other is to invest in virtual currencies, that is, It is similar to Bitcoin, but you need to choose an old and reliable platform, one with a longer history and a good reputation. You can look at AEX and Huobi. If you want long-term financial management, you can choose AEX financial management. Supermarket

㈣ Where to check the blockchain transaction ID

Here we use the Ethereum blockchain wallet as an example. Little Fox is an encrypted wallet and enters the blockchain APP. Entrance and exit. After entering, obtain the wallet address, and then use the Ethereum blockchain searcher to enter the homepage of the Etherscan official website. You can obtain the following blockchain transaction ID information:
1. The latest block
2. The latest Transactions that occurred
Extended information:
The transaction process of the blockchain may seem mysterious and cumbersome, but in fact it is not necessarily that difficult to actually talk about it.
Step 1: Owner A uses his private key to sign a digital signature on the previous transaction (bitcoin source) and the next owner B, and appends this signature to the end of the currency to create Transaction order. At this time, B uses the public key as the recipient address.
Step 2: A broadcasts the transaction order to the entire network, and the Bitcoin is sent to B. Each node will receive the transaction information and include it in a block
At this time, for B, the Bitcoin will beIt appears in the Bitcoin wallet at the time, but cannot be used until the block is confirmed successfully. At present, a Bitcoin can only be truly confirmed after being confirmed by 6 blocks from payment to final confirmation.
Step 3: Each node obtains the right to create a new block by solving a mathematical problem and strives to receive Bitcoin rewards (new Bitcoins will be generated in the process)
At this time, the nodes repeat Try to find a value so that after feeding the three parts of the value, the Hash value of the last block in the blockchain, and the transaction order into the SHA256 algorithm, the hash value are all 0), that is, the solution to the mathematical problem is found.
Step 4: When a node finds a solution, it broadcasts all timestamped transactions recorded in the block to the whole country, and is checked by other nodes in the entire network.
At this time, the timestamp is used to prove that a specific block must indeed exist at a specific time. The Bitcoin network obtains the time from more than 5 nodes, and then takes the middle value to become a timestamp.
Step 5: Other nodes in the entire network check the correctness of the accounting of the block. If there are no errors, they will compete for the next block after the legal block, thus forming a legal accounting blockchain.

㈤ What projects are there for blockchain investment?

Zilliqa is positioned as the underlying public chain, and its core competitiveness is to use sharding technology to significantly increase throughput TPS (that is, transaction processing speed) ). In the latest experiment, the Zilliqa test network’s processing capacity reached 2488TPS, which is more than 100 times that of Ethereum’s top speed of 20TPS and 355 times that of Bitcoin! Through sharding technology, when there are more nodes in the network, the transaction processing speed will be higher. When the number of nodes reaches tens of thousands, the transaction speed is expected to reach the speed of centralized institutions such as VISA.

The token of the Zilliqa project is called ZIL, and it has been circulated and traded on 23 exchanges. It is supported by mainstream exchanges such as Huobi and Binance. It is very convenient to participate. The maximum supply of ZIL is 21 billion, of which 12.6 billion will be released directly through the contract, and the other 8.4 billion will be released within 10 years using mining rewards.

Zilliqa’s mainnet will be launched at the end of 2018 or early 2019. Mining rewards are generous, especially in the early days. Zilliqa’s mining electricity cost is only 1/9 of Ethereum’s, which means it consumes less energy and is more feasible. In addition, mining can be carried out through GPU graphics card mining machines, and ZIL and ETH can be mined simultaneously, bringing higher profits to miners.

㈥ What is investment in public chain tokens?

Investing in public chain tokens is equivalent to investing in a new generation of blockchain models. Based on the characteristics of blockchain that cannot be tampered with and are trustworthy, blockchain The real value of the chain lies in realizing the blockchainization of real-world materials.Digitally coding all products and establishing a complete digital blockchain transaction system will greatly reduce costs and increase efficiency.

㈦ Is there any reliable public chain in the blockchain industry?

Is there any reliable public chain in the blockchain industry?

In the blockchain industry, both practitioners and investors must be familiar with public chains. Whenever a new project is born in the industry, it must have something to do with the public chain. But in fact, looking at the entire blockchain industry, there are not many mature and stable public chains. Currently, there are three main system types in the blockchain industry: public blockchain, joint blockchain, and private blockchain.

Public blockchain is often referred to as a public chain in the industry. It means that any individual or group in the world can participate in the accounting and transaction process of the entire system, and at the same time, its transaction records can be effectively obtained by the system. Confirmed blockchain mainnet, in the industry, we usually call this publicly writable nature "open source". The public chain is the earliest and most widely used blockchain system in the industry.

United blockchain, also known as alliance chain, the alliance chain system is not open source, but multiple pre-selected nodes are designated as bookkeepers within a certain group, and each block is generated by all The pre-selected nodes jointly decide that other nodes can participate in transactions but have no right to participate in the accounting process. It is essentially similar to the custody accounting in the financial industry and can be called a "semi-centralized" blockchain system. This system is more stable, but is not suitable for wide-scale popularization and application.

Private blockchain is a private chain. This kind of system is more closed, and simply uses the underlying technology of the blockchain for the accounting process. However, its network system is not open source, and developers have exclusive writing rights. The developer here can be a company or an individual. Currently, many traditional financial industries want to try private chain development, but their application products are still being explored.

Among the above three system types, the public chain system is undoubtedly the one that attracts the most attention from the industry. Compared with the other two types, the public chain has the advantages of open source, decentralization, and wide ecological scenarios, and is also more conducive to global promotion and layout. However, due to various reasons such as technology, capital, and time, the industry’s public chain research situation is generally not optimistic.

The three most well-known public chains in the industry, the Bitcoin public chain, the Ethereum public chain, and the EOS public chain, all have different problems. The closed system of the Bitcoin public chain forms an island of value, which cannot be solved by a hard fork; the problems of Ethereum transaction congestion and excessive handling fees are always difficult to solve; and within EOS, due to insufficient ecological scale, it is difficult to support excellent ecological applications. At the same time, the CPU Problems such as skyrocketing and insufficient memory gradually emerged.

In short, in order to determine whether a public chain is reliable, you need to understand whether the operating logic of its public chain network itself is stable, whether its ecological structure capacity is sufficient, whether its community consensus is strong, and whether its applications Does the scene haveLong-term hematopoietic function, etc. Of course, the blockchain industry is currently in the development and exploratory stage, and it will take time to prove a reliable and stable public chain.

㈧ Anyone who understands blockchain investment would like to ask how everyone participates in blockchain investment and whether the income from blockchain investment is safe

I have the best say on this. I have been in the cryptocurrency industry for five or six years. I have bought equipment, traded on major exchanges, opened contracts, and added leverage. In recent years, I have actually made less money and lost more money. Later I discovered that investing in blockchain is actually equivalent to stock trading. Those who have lost money want to continue participating in the hope of a comeback, and those who have made money want to continue participating in the hope of making a lot of money. If you go back and forth like this, plus you don’t know much about what blockchain is, you will naturally not get much benefit, and you will often be harvested like leeks.
Recently, a friend of mine in the currency circle introduced me to a company called Hada Meta. It is headquartered in Singapore and has a technical team in China. My friend asked me to listen to the sharing given by their technical staff, and my eyes brightened. Let me share with you my experience.
First of all, when I first came into contact with the company Hada Meta, I subconsciously thought that they were probably similar to the companies I had encountered before. They just talked and tricked you into buying equipment. But the people who listened to their introduction for most of the day did not mention the equipment at all. They kept sharing how to choose reliable investment products in the blockchain market, and how to participate in order to maximize returns and guarantees. Investment safety surprised me, and I started to get a little interested.
Then they analyzed to me why I made less and lost more when I invested in blockchain before. In the final analysis, it was because I didn’t do a good job of “selecting” and “investing”. I really don’t know how to choose a good blockchain investment product. When I see which project is popular, I invest in it, and I can’t help but buy equipment, or wait for it to go online and speculate directly. As a result, they told me that my investment method was most likely to be cut off. I thought about it carefully. After all, I was already a step later than others when I participated, so the benefits I received were naturally less.
Finally, they specially designed a blockchain product investment plan for me based on my actual situation. They told me that I am suitable for short-term investment. In this case, I should not buy equipment because it is not worth it and the cost is high. Short-term investment may only last a few months, and there is no need to buy equipment. The dividend period for short-term investment is the testing period before the public blockchain goes online, so they suggested that I rent cloud computing power to participate. This way, the risk is small, the investment is small, and the returns are high.
To be honest, I have never seen a team like theirs. Maybe if I sell the equipment directly, I can make more money, but they did not do that. Instead, they advised me to do what I can. I think it’s pretty reliable
