What does blockchain transaction ID mean

1.

first, define the

blockchain as an open network ledger. It originated from bitcoin and is the underlying technology of bitcoin. In bitcoin transactions, all the information of transaction records will be packaged into a "block" for storage. With the expansion of information exchange, one block links with another, forming a blockchain

Second, the digital currency represented by bitcoin is a point-to-point e-cash system. Among them, every transaction will broadcast to all participants in the network, and it will be recorded in the account book after repeated confirmation, which is called "blockchain". Each participant will have his own account book. In this way, when false information occurs, it can be broken through mutual verification, so as to ensure network security

in the blockchain, every node is equal, and there is no centralized management organization. This "decentralized" feature makes the blockchain do not need to rely on a third party, its operation does not need any human intervention, and it can independently conct self verification. In addition, the network of blockchain is open to the world, and anyone can query data through the public port, so the whole system is highly transparent

In a word, blockchain is a reliable database and a reliable "account book". In the future, it will be applied in cross-border payment, securities, loans, voting, etc. For example, in cross-border payment, with the security of blockchain, you can remit money to the world anytime and anywhere, which saves a lot of intermediate links and high fees

2. Blockchain is an important concept of bitcoin. In essence, it is a decentralized database and the underlying technology of bitcoin. Blockchain is a series of data blocks generated by cryptography. Each data block contains the information of a bitcoin network transaction, which is used to verify the validity of the information (anti-counterfeiting) and generate the next block
in a narrow sense, blockchain is a kind of chained data structure, which is composed of data blocks connected in sequence according to the time sequence, and is a distributed account that can not be tampered with and forged by cryptography. In a broad sense, blockchain technology is a new distributed infrastructure and computing paradigm, which uses blockchain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, uses cryptography to ensure the security of data transmission and access, and uses intelligent contract composed of automated script code to program and operate data
blockchain and big blockchain are not the same concept. Big blockchain should be the name of a company. Bitcoin, Ethereum and decent are all successful cases of blockchain technology.

3. The ID of bitcoin transaction you said should be the address of bitcoin wallet. If the address of bitcoin wallet is wrong, you can't send out bitcoin, it will prompt you to go wrong. Another is that bitcoin transactions will be broadcast all over the network. The records of bitcoin transactions can be queried by anyone and cannot be modified

a bitcoin address is like a physical address or an e-mail address. This is the only information you need to provide when someone pays you bitcoin. An important difference, however, is that each address should only be used for a single transaction

block chain is a public record of bitcoin transactions in chronological order. The block chain is shared by all bitcoin users. It is used to verify the permanence of bitcoin transactions and prevent double consumption.

4. Blockchain is an important concept of bitcoin. It is essentially a decentralized database. At the same time, as the underlying technology of bitcoin, it is a series of data blocks generated by using cryptographic methods. Each data block contains a batch of information about bitcoin network transactions, Used to verify the validity of its information (anti-counterfeiting) and generate the next block.

5. 1. The value of bitcoin does not lie in its computing method and encryption algorithm. 2. The calculation and proction of bitcoin need time, equipment loss and electricity cost. 3. The total output of the algorithm is limited. 4. Some foreign and domestic objects have supported bitcoin payment, which makes it have the preliminary property of currency. 5. There is no difference between bitcoin and the legal currency of any country in its own value. A piece of printed paper or PVC does not have actual value. It can not have the characteristics of rare metals like gold. 6. The biggest risk of bitcoin is that no country, bank, military or government can guarantee its credibility. 7. At present, it seems to be just a virtual currency with speculation value. 8. Its circulation value is certainly not as popular as q-coin in China. For example, few people in second tier cities know about bitcoin, let alone let it admit its value.

6. Blockchain is a technology and bitcoin is a proct
the proct has been finalized, you can only choose to accept or not, but the technology can be applied to all walks of life

7. 1. Block identity is the user's pass in TTC ecological community, which is bound with block identity ID
the block ID is equivalent to the QQ number in Tencent proct ecosystem. The differences between the block ID and QQ number are as follows:
a. the user's personal data will be stored in their respective block address, and the user can login through the block ID for management. b. Block ID is developed based on blockchain technology, which has the characteristics of decentralization, distributed accounting, anonymity, security and controllability of blockchain
2. Block ID is the pass of TTC ecological community, which can be used to log in to all applications in TTC ecological community with one click, including various dapps launched in the future. There is no need to register repeatedly, so it is more convenient to collect and pay. Now there is a six digit number for registration.

8. It's said that everyone has an ID. according to the ID information, you can find all the information of the person, and all the files are in the ID
