Ethereum: Signatures behind the scenes

When sending a transaction on the Ethereum network, you might ask how it is checked without disclosing your private key. In this article, we will dive into the digital signature world and explore how they work.

What are digital signatures?

Digital signature is a mechanism that allows users to show the property and authenticity of the digital message, such as transactions on the Ethereum network. This is basically a way to sign your messages using encryption that makes them constant and counterfeit.

How do digital signatures work in Ethereum?

In the Ethereum network, transactions are signed using a single algorithm called Ethash (Sha-256 hash function variant). The signature is generated by mixing the transaction data with a private key. This creates a digital message related to your public address and private key.

Here are step by step:

• Development of transactions : A new transaction containing the public address of the sender, the public address of the recipient, the transaction data, and any other relevant information is created.

• Private key derivation

  : Ethereum blockchain generates “(H) unique” Hash feature based on private key.

Signature Generation : The transaction is signed using the Hash H feature that creates a digital signature corresponding to the transaction data.

• Transaction Transmission: The signed transaction is forwarded to the Ethereum network where it is checked by the nodes.

How do nodes check signatures?

Ethereum Networks are expected to check transactions and signatures using various methods:

1
Check based on Hash : The nodes check that the digital signature corresponds to the expected deal of the transaction.

• Chain Validation

  

  : The nodes check that the transaction is part of a valid block in the blockchain, which guarantees that it is not distorted or modified during the transmission.

How do nodes get your private key?

The nodes do not directly enter the private key; Instead, they use different methods to get information about:

1
Blockchain Storage : The nodes memorize a copy of the blockchain Ethereum, which includes Hash H Function and Private Key used for signature for signature.

• Node configuration : Many nodes are configured with pre -generated private keys, or have a mechanism to obtain them using your public address.

Conclusion

In summary, digital signatures on the work of the Ethereum network by signing transactions with private key, generating a unique digital report related to your public address and private key. The nodes check these signatures using the hash -based inspection and chain validation, ensuring the authenticity and integrity of the transaction data. While this may seem mysterious, understanding how digital signatures work can provide valuable information about the Ethereum network and its internal mechanisms.
