Understanding of IDS of Transactions in Ethereums
When sending a cryptocurrency, such as Bitcoin, to another user on a blockchain network like Ethereum, a unique transaction is created that contains different key information. Among these is the ID of transactions (TXID), also known as “Transaction Hash”. In this article, we will deepen what each component means and how it is used in ethereum transactions.
What is a transaction hash?
A transaction has a digital digital imprint or a unique identifier assigned to each bitcoin transaction on the blockchain. It is essentially a 66 -words hexadecimal string that represents the whole data of the transactions. The Hash Function takes the transactions data (including the Sender, the Recipient, the Amount and Other Details) Such as input and generates a fixed length output.
how is the transaction id created?
When creating a new bitcoin transaction in ethuming the `eth_sendransation 'or the web3.js bookshop row tool, the system generates a univocal transaction hash according to the following factors:
- Input address : The Public Key and the Sender Address.
- Output Addresses : The Recipients of the Payment.
- Amount : The value in the phase of transferring (in this case, Bitcoin amount).
- Timestamp : The current timestamp in a few seconds from 1 January 1970.
The transaction has generated using a cryptographic algorithm that takes these inputs as inputs and produces a fixed length output. This guarantees that each transaction has an unchangeable and unique digital imprint.
the hash on the transaction lhs is the same as txid?
No, the hash shown on the left side (LHS) of a bitcoin transaction is not the same as the ID of the Transaction (TXID). While both are hexadecimal strings, they have different structures and content. TXID generally has 66 characters and can be more or less than this length.
For Example:
* Hash Transaction :0x1234567890ABCDEF
* Transaction ID :0XF43A8E7C9485CD
The hash on the LHS is a fixed length output that represents the whole data of the transaction, while the txid is a shorter and more descriptive string indicating the specific details of the transaction.
in summary
To summarize, the transaction id (TXID) in an ethereum transaction is a univocal digital imprint created by the system based on the input address, the quantity, the timestamp and the encryption hash. The hash shown on the transaction LHS is not the same as txid. Understanding these concepts is essential to work with Bitcoin transactions and interact with the Ethereum Network.
Example of Code
Here is an example in javascript using the web3.js bookshop to generate a simple Bitcoin Transaction:
Javascript
Const Web3 = Requirements ('Web3');
Const address = '0x1234567890ABCDEF';
Const Txhash = New Uint8array (66);
Txhash [0] = 0; // Input Address (0x00000000)
Txhash [1] = 0; // Input Address (0x00000001)
// ...
Const transaction = {{
from: '0x1234567890ABCDEF',
A: Address,
Value: '1.2 Bitcoin',
Timestamp: Math.Floor (New Date (). Gettime () / 1000),
};
Web3.eth.sendransation (Transaction, (Error, Result) => {
If (! Error) {
Console.log ('txid:', txhash.join (''));
} Other {
console.error (Error);
}
});
`
This code generates a basic bitcoin transaction with the recipient’s address ‘0x1234567890ABCDEF’. The results txid is printed on the console.
