⑴ What kind of shared ledger and database is blockchain?
Distributed. Blockchain is a distributed shared ledger and database that can break through "data barriers" between departments and realize information and data sharing, thereby improving collaboration efficiency and reducing communication costs, resulting in a high degree of dispersion, long management chains, and multiple links involved. . Blockchain is a term in the field of information technology.
⑵ 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."
< p>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.
⑶ How to implement query and search on blockchain data
Blockchain is a distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm, etc. New application models of computer technology. The so-called consensus mechanism is a mathematical algorithm in the blockchain system that enables different nodes to establish trust and obtain rights and interests.
In a narrow sense, blockchain is a chain data structure that combines data blocks in a sequential manner in chronological order, and is cryptographically guaranteed to be non-tamperable and non-tamperable. Unforgeable distributed ledger.
Broadly speaking, blockchain technology uses block chain data structures to verify and store data, uses distributed node consensus algorithms to generate and update data, and uses cryptography to ensure data mastery. Security of transmission and access, a new distributed infrastructure and computing paradigm that utilizes smart contracts composed of automated script code to program and manipulate data.
Generally speaking, the blockchain system consists of the data layer, network layer, consensus allocation layer, incentive layer, contract layer and application layer working together to complete the query and search of data.
⑷ It is said that the blockchain is a big ledger, where is all this information recorded?
The blockchain is a big ledger of the Bitcoin network, and each block is equivalent to A page in the ledger. Currently, each block of Bitcoin mainly records data such as block header, transaction details, transaction counter, and block size. The "block header" contains all information except transaction information, mainly including the hash value of the previous block header: used to guarantee the block.
⑸ How to check whether a blockchain project is reliable
Is the Omepe Omechain European and American Manor real?
⑹ Blockchain technologyTechnology
Background: After the birth of Bitcoin, it was discovered that the technology was very advanced, and blockchain technology was discovered. Bitcoin and blockchain technology were discovered at the same time.
1.1 The purpose of the birth of Bitcoin:
①Currency transactions have records, that is, ledgers;
②The disadvantages of centralized institution accounting - it can be tampered with; Yi Chaofa
Bitcoin solves the first problem: anti-tampering - hash function
1.2 hash function (encryption method)
① Function: convert any A string of length, converted to a fixed-length (sha256) output. The output is also called a hash value.
② Features: It is difficult to find two different x and y such that h(x)=h(y).
③Application: md5 file encryption
1.3 Blockchain
①Definition
Block: Split the general ledger into zones Block storage
Blockchain: On each block, add a block header. It records the hash value of the parent block. By storing the hash value of the parent block in each block, all blocks are connected in order to form a blockchain.
②How does the blockchain prevent transaction records from being tampered with?
After the blockchain is formed, tampering with any transaction will cause the hash value of the transaction block to be different from that of its sub-blocks. , tampering was discovered.
Even if you continue to tamper with the hash value in the sub-block header, the hash value in the sub-block will be different from that in the grandchild block, and the tampering will be discovered.
1.4 The essence of blockchain
①The essence of Bitcoin and blockchain: a big ledger visible to everyone, only recording transactions .
②Core technology: Through cryptographic hash function + data structure, it ensures that the ledger records cannot be tampered with.
③Core function: Create trust. Fiat currency relies on government credibility, and Bitcoin relies on technology.
1.5 How to trade
①To conduct transactions, you need an account number and password, corresponding to the public key and private key
Private key: a string of 256-bit binary numbers , no application is required to obtain it, and you don’t even need a computer. You can generate the private key by tossing a coin 256 times.
The address is converted from the private key. The address cannot reverse the private key.
The address is the identity, which represents the ID in the Bitcoin world.
After an address is generated, it can only be known by everyone if it enters the blockchain ledger.
②Digital signatureTechnology
Signature function sign (Zhang San’s private key, transfer information: Zhang San transfers 10 yuan to Li Si) = signature of this transfer
Verify Korean verify (Zhang San’s Address, transfer information: Zhang San transfers 10 yuan to Li Si, signature of this transfer) = True
Zhang San uses his own private key to sign this transaction through the signature function sign().
Anyone can verify whether the signature was issued by Zhang San himself who holds Zhang San's private key by verifying the Korean vertify(). It returns true, otherwise it returns false.
sign() and verify() are cryptographically guaranteed not to be cracked. ·
③Complete the transaction
Zhang San will provide the transfer information and signature to the entire network. Under the premise that the account has a balance, after verifying that the signature is true, it will be recorded in the blockchain ledger. Once recorded, Zhang San's account will be reduced by 10 yuan, and Li Si's account will be increased by 10 yuan.
Supports one-to-one, one-to-many, many-to-one, and many-to-many transactions.
In the Bitcoin world, private keys are everything! ! !
1.6 Centralized Accounting
① Advantages of Centralized Accounting:
a. No matter which center keeps accounts, don’t worry too much
< p> b. Centralized accounting, high efficiency②Disadvantages of centralized accounting:
a Denial of service attack
b Stop service after getting tired
p>c Central institutions are vulnerable to attacks. For example, destroying servers and networks, committing self-intrusion, legal termination, government intervention, etc.
All attempts at confidential currencies with centralized institutions in history have failed.
Bitcoin solves the second problem: how to decentralize
1.7 Decentralized accounting
①Decentralization: Everyone can keep accounts. Everyone can keep a complete ledger.
Anyone can download open source programs, participate in the P2P network, monitor transactions sent around the world, become an accounting node, and participate in accounting.
② Decentralized accounting process
After someone initiates a transaction, it is broadcast to the entire network.
Each accounting node continues to monitor and continue transactions across the entire network. When a new transaction is received and the accuracy is verified, it is put into the transaction pool and continues to be propagated to other nodes.
BecauseDue to network propagation, the transactions of different accounting nodes at the same time are not necessarily the same.
Every 10 minutes, one person is selected from all accounting nodes in a certain way, and his transaction pool is used as the next block and broadcast to the entire network.
Other nodes delete the transactions that have been recorded in their own transaction pool based on the transactions in the latest block, continue accounting, and wait for the next selection.
③ Features of decentralized accounting
A block is generated every 10 minutes, but not all transactions within these 10 minutes can be recorded.
The accounting node that obtains the accounting rights will be rewarded with 50 Bitcoins. After every 210,000 blocks (approximately 4 years), the reward is halved. The total amount is about 21 million, and it is expected to be mined in 2040.
Recording the reward of a block is also the only way to issue Bitcoin.
④ How to allocate accounting rights: POW (proof of work) method
Compete for accounting rights by calculating mathematical problems on several accounting points.
Find a random number that makes the following inequality true:
There is no other solution except traversing the random numbers starting from 0 and trying your luck. The process of solving the problem is also called mining.
Whoever solves the problem correctly first will get the accounting rights.
If a certain accounting node finds the solution first, it will announce it to the entire network. After other nodes verify that it is correct, a new round of calculation will start again after the new block. This method is called POW.
⑤ Difficulty adjustment
The generation time of each block is not exactly 10 minutes
As Bitcoin develops, the computing power of the entire network does not increase.
In order to cope with changes in computing power, the difficulty will be increased or decreased every 2016 blocks (approximately 2 weeks), so that the average time for each block to be generated is 10 minutes. < /p>
What is blockchain? There are really too many explanations for this problem nowadays.
To put it simply, it is a technology. It can solve our current trust mechanism and transaction efficiency problems to a certain extent. What is blockchain? This problem is also faced by many newbies to blockchain. As a distributed ledger technology, it can bring us many surprises and surprises. Many blockchain companies are using blockchain technology to provide solutions based on some industry pain points, thereby solving the pain points of certain industries.
