Election algorithm of blockchain

1. What is hash algorithm? How to ensure the fairness of mining
hash algorithm is a cryptographic algorithm that can only encrypt, but not decrypt. It can convert any length of information into a fixed length string
this string has two characteristics:
1. Even if the input value changes only a little, the output hash value will be very different
2. Only exactly the same input value can get exactly the same output value
3. There is no rule between the input value and the output value, so the input value cannot be calculated by the output value. In order to find the specified output value, we can only use enumeration method: constantly change the input value to find the output value that meets the conditions
hash algorithm ensures that the results of bitcoin mining can not be deced reversely. Therefore, the miner's continuous operation is essentially brutally cracking the correct input value. Whoever finds the first one will get the bitcoin reward.

2. blockchain encrypts the transaction information in a transaction block by hash algorithm, and compresses the information into a hash string composed of a string of numbers and letters
jinwowo group analyzes the functions of its hash algorithm as follows:
the hash value of the blockchain can uniquely and accurately identify a block. Any node in the blockchain obtains the hash value of the block through simple hash calculation, and the calculated hash value does not change, which means that the information in the blockchain has not been tampered with.

3. Blockchain is a decentralized distributed ledger system, which can be used to register and issue digital assets, property rights certificates, points, etc., and transfer, pay and trade in a point-to-point manner. Compared with the traditional centralized ledger system, blockchain system has the advantages of complete disclosure, tamper proof, multiple payment prevention, and does not rely on any trusted third party
e to the high network delay in peer-to-peer network, the transaction order observed by each node can not be completely consistent. Therefore, the blockchain system needs to design a mechanism to reach a consensus on the sequence of transactions that occur in the same time. This algorithm to reach consensus on the order of transactions in a time window is called consensus mechanism

4. Blockchain encryption algorithm
asymmetric encryption algorithm is a function that converts the original plaintext file or data into a series of unreadable ciphertext codes by using an encryption key. The encryption process is irreversible. Only holding the corresponding decryption key can the encrypted information be decrypted into readable plaintext. Encryption enables private data to be transmitted through the public network under the condition of low risk, and protects the data from being stolen and read by the third party
the core advantage of blockchain technology is decentralization, which can realize point-to-point transaction, coordination and cooperation based on decentralized credit in a distributed system without mutual trust by means of data encryption, time stamp, distributed consensus and economic incentive, so as to solve the high cost and low cost of centralized institutions Low efficiency and data storage insecurity provide solutions
the application fields of blockchain include digital currency, token, finance, anti-counterfeiting traceability, privacy protection, supply chain, entertainment, etc. with the popularity of blockchain and bitcoin, many related top domain names have been registered, which has a great impact on the domain name instry.

5. The origin of blockchain comes from "bitcoin: a peer-to-peer e-cash system" published by Nakamoto in 2008. According to this concept, the first proct "bitcoin" was born. The origin of blockchain technology is usually attributed only to the actions of some mysterious geniuses who work under the pseudonym of Nakamoto. This view of history often makes the technology seem almost magical and difficult to understand. When people understand the actual history behind the development of these systems, it is more fundamental. In this section, I will outline the most important topics in decades of research on consensus algorithms and distributed systems that led to the creation of blockchains.

6. Now it's just testing, there's no official release, there's no use for it?

7. I just came into contact with this project recently. I hope it can help you
FST network is a blockchain application technology service platform, which is committed to further application of blockchain. Its pillar proct FST network engine mole is an infrastructure built for enterprises to save development time. The FST network engine mole, through comprehensive molar logic construction, allows anyone to manage the certificate business without coding environment, reces the threshold of the blockchain development community, and saves the development cycle.

8. Zhongan chain uses Byzantine fault-tolerant algorithm with weight. Compared with the traditional workload proof algorithm, Zhongan chain's algorithm has a great improvement in block speed and consensus efficiency.
