怎么查区块链交易记录,如何查询区块链交易id

『一』Where to query Ethereum transaction records

It has its own browser, both Ethereum and Ethereum use one, and the code developed based on Ethereum Coins can also be queried on the Ethereum blockchain browser, and usdt can be queried on the Bitcoin blockchain browser.
On non-small accounts, you can view the Ethereum market, but you cannot trade. If you want to invest, you can go to a digital currency exchange. Currently, the mainstream digital currency exchanges on the market include Binance, Huobi.com, Bitnet, etc. Here we use the Ethereum blockchain wallet as an example. Little Fox is an encrypted wallet and the entrance and exit to the blockchain APP. 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:
Owner A uses his private key to verify the previous transaction ( Bitcoin source) and the next owner B sign a digital signature, and append this signature to the end of the currency to create a transaction slip. At this time, B uses the public key as the recipient address. 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. For B, the Bitcoin will be immediately displayed in the Bitcoin wallet, but It 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. Each node obtains the right to create a new block by solving a mathematical puzzle and strives to be rewarded with Bitcoins (new Bitcoins will be generated in the process).

『二』How to check other people’s blockchain information

1. If you are querying account balance, historical transaction data of the account and other information, it is recommended to directly enter the wallet address to query; For information related to a certain transfer, such as whether it has been received and how the progress is, it is most convenient to enter the transaction ID. Of course, the blockchain browser can not only query your own account, but also query all contacts of other people's accounts: display all contact addresses/tags with transaction records, addresses with more than 10,000 transactions, and take the most recent 1 Contact display for 10,000 transactions In summary, SixPencer’s new asset tracking and management tool can provide more comprehensive query and analysis functions than a blockchain browser or wallet. As a tool product, it is intended to assist users.
2. It can be queried through the blockchain browser. In the blockchain browser, we can know what transactions a wallet address has conducted, how many assets are on the account, etc. You can view it with a blockchain browser. Enter the wallet address you want to query in the search input box. If the address you enter is incomplete, but this address has been ETH traded or queried on the blockchain before, the input box will automatically query it for you

『三』 Where to check the blockchain transaction ID

Here we use the wallet of the Ethereum blockchain as an example. The little fox is an encrypted wallet and enters the blockchain.The entrance and exit of the APP. 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 Bitcoins will appear in your Bitcoin wallet immediately, but cannot be used until the block is confirmed. At present, a Bitcoin can only be truly confirmed after being confirmed by 6 blocks from payment to final confirmation.
The third step: Each node obtains the right to create a new block by solving a mathematical problem, and strives to be rewarded with Bitcoins (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.
