Understanding the transaction -IDS in Ethereums
If you send cryptocurrency like Bitcoin to another user in a blockchain network like Ethereum, create an exclusive transaction that contains a lot of important information. Among them is the transaction -ID, which is also referred to as the “transactionhash”. In this article we will deal with what every component means and how it is used in Ethereum transactions.
What is a transactionhash?
A transaction -Hash is a fingerprint or a clear identifier that is attributed to every Bitcoin transaction in the blockchain. It is essentially a 66 -word hexadecimal sequence that represents all transaction data. The Hash function takes over the transaction data (including the sender, the recipient, the amount and other details) such as input and generates an output with a fixed length.
How is the transaction -id created?
If you create a new Bitcoin transaction on Ethereum using the command lines -Tool for ETH_SENDTRANSAction or Web3.js library, the system generates an exclusive transaction -Hash that is based on the following factors:
- Entry address : The public key and sender address.
- Output addresses : The receiver of the payment.
3.
- TIMESTAMP : The current date and clockwork record in seconds since January 1, 1970.
The transaction -Hash is generated using a cryptographic algorithm, which carries these inputs as an entrance and generates an output with a fixed length. This ensures that each transaction has an unchangeable and exclusive digital print.
Is the hash the same in the transaction as TXID?
No, the hash that is shown on the left (LHS) of a Bitcoin transaction is not the same as the transaction -id (TXID). While both hexadecimal strings are, they have different structures and content. TXID usually has 66 characters and can act around this length.
For example:
* Transaction hash
: 0x1234567890abcdef
* Transaction -ID : 0xf43a8e7c9485cd
Hash in the LHS is an output with a fixed length, which represents all transaction data, while TXID is a shorter and more descriptive sequence that shows the specific details of the transaction.
Time -fitting
In summary, the transaction -id (TXID) in an Ethereum transaction is an exclusive digital print that was created by the system based on entry, quantity, date and time and cryptographic hash. The hash shown in the LHS transaction is not the same as TXID. Understanding these concepts is of essential importance for working with Bitcoin transactions and interaction with the Ethereum network.
Code Example
Here is an example in JavaScript that uses the Web3.js library to generate a simple Bitcoin transaction:
`JavaScript
Const Web3 = required (‘Web3’);
Address Const = ‘0x1234567890abcdef’;
Const Txhash = New Uint8array (66);
Txhash [0] = 0; // input address (0x00000000)
Txhash [1] = 0; // input address (0x00000001)
// …
Constt transaction = {
From: ‘0x1234567890abcdef’, ‘,
To: address,
Value: ‘1.2 Bitcoin’,
Time temple: Math.floor (new date (). Testtime () / 1000),
};
Web3.eth.sendtransaction (transaction, (error, result) => {
if (! error) {
console.log (‘txid:’, txhash.join (”));
} Others {
console.error (error);
}
});
`
This code generates a basic Bitcoin transaction with the address of the recipient 0x1234567890abcdef. The resulting TXID is printed on the console.
