Decoding a public key: Understanding Ethereum transactions
In the vast and complex world, the cryptocurrency, the recipient’s public key can be a challenge. This article will deepen the concept of restoring the public key from the Ethereum transaction and to provide information on whether this information can be obtained.
What is a transaction?
The Ethereum transaction is a message sent by one user to another. It contains data such as the sender’s public key, the recipient’s public key and the amount of ether (ETH). The transaction is verified by the Ethereum network using complex cryptographic algorithms, which ensures its integrity.
How does the transaction identify the public key?
The transaction usually includes areas that identify its owner (sender), including his public key. However, these fields are not directly linked to the public key itself; They contain only links to it for verification purposes. For example, in the TX Ethereum blockchain data structure, you will find a field called” Z “that contains a sender’s public key.
Obtaining a public key from the transaction
To restore the public key of the recipient of the Ethereum transaction, we need to understand how the network identifies and checks transactions. Here are general steps:
- This txide contains information about the transaction, including its sender and receiver.
- Pole : As already mentioned, the data structure “In the data on transactions, the sender’s public key contains. However, this field is not directly linked to the recipient’s public key.
- Signature of the recipient : To verify the network transaction, it will verify that it was signed by the intended recipient (the person whose balance of the Ethereum transaction has been sent). The recipient’s signature ensures that the transaction was actually determined for them.
Can we get a user’s public key?
Now let’s deal with your question: Is it possible to get a user’s public key if we have a transaction from this user in the portfolio?
Unfortunately not. In Ethereum, since the network has been sent and verified a transaction, it is not possible to obtain or obtain the sender’s public key directly. The sender’s public key is only available to check the transaction, not to obtain it.
The “Do” field contains a sender’s public key, but this information is intended only for verification purposes and does not provide access to the consignor’s personal data such as its public key.
Conclusion
By obtaining a public key from the recipient of the Ethereum transaction, it may be difficult due to its role in verifying transactions, this information cannot be obtained directly. Field `de contains links to the sender’s public key only for verification purposes.
However, if you need to check the transaction or send/receive funds, there are other available methods that do not require access to private key key or the recipient’s public keys. This includes the use of Ethereum Wallet Application or interactions with third -party services that support safe and private transactions.
