In Ethereum: How the output of a transaction is signed

In a transaction in the Ethereum network, two key components for the integrity and safety of the blockchain are of crucial importance: the input transaction (TX) and the starting transaction (TXutput). However, before these transactions can be included in a block, they must be signed by the sender. This process ensures that the sender’s identity is checked and that a change in the data cannot be made without consent.

To understand how this signature process works, disassemble the steps involved:

• Creation of transactions : If a new transaction (TX) is created in the Ethereum network, it contains a TXE transaction pointer (former transaction), which serves as an entry for TX. This hash point represents the previous block or the transaction in the blockchain chain.

• Creation of signature

  : The sender of the new transaction (TX) must generate a digital signature for the new output and the signed TXE. This process is to encrypt the entire transaction, including input data and output data, using a cryptographic algorithm such as ECDSA (digital signature algorithm of the elliptical curve).

• Checking the signature : If a minor receives the transaction, he checks whether the digital signature generated by the sender corresponds to the hash, which serves as an entry for the TX. If the signatures correspond, the identity of the sender was confirmed. This process ensures that the changes to data are not falsified without knowledge or control of the sender.

• Exit -check : The minor also checks the signature of the starting transfer action (TXoutput) by checking whether it is a valid digital signature for the specific data on this transaction. If the signatures correspond, the data has been successfully changed.

• Creation of blocks : As soon as the input and output transactions have been properly signed, the minor creates a new block that contains these transactions and all other relevant information such as transaction metadata. The block is then added to the blockchain chain.

In summary, it can be said that the signing of the production of a transaction ensures that the identity of the sender has been checked and its actions have been approved on the blockchain. This process helps maintaining the integrity of the Ethereum network and offers users a safe means of trusting transactions on the platform.
