Ethereum: Why is Hash Signature different for each input in a multi -wire transaction?
In Ethereum, when a multi -stage transaction is performed, the hash signature transactions are different from the input hash. Initially, this may seem contrast, but it is essential to understand why this choice of design was made.
BIP 14: Hashy and Signature Hashy
The interface of the Ethereum Block block (BPI) allows multiple inputs with a multiple transaction. To adapt these cases to these cases, the BIP 14 defines subjects that are medium hashmas that allow effective transactions.
When creating the site, the Ethereum virtual machine (EVM) replaces the previous Scripubkey for each recording, which leads to different signature hashs. This replacement is essential as EVM must ensure that the output addresses and transaction values correspond to the expected.
Why different signatures?
The different signatures are not arbitrary; They serve a specific purpose:
1
- Efficiency
: EVM can use these pads to optimize transactions processing, reduce calculation overheads and improve overall efficiency.
- Security : The use of different inputs ensures that transactions cannot be carried out mercilessly by using weaknesses in the system.
At the end
The multiple signature transaction differs from its input hash due to the replacement of “Scripubkeys”. This design option is rooted in maintaining sequence, optimizing transactions and security processing. At Ethereum, we believe that EVM’s ability to replace the inputs properly and safely, allowing us to perform transactions effectively and safely.
An example of using case
Consider a multiple transaction in which two users want to send funds from one account to another using another “Scripubkeys”. To perform this transaction, replacing ScripubKeys will ensure that:
- Output addresses meet expectations.
- Transaction processing is effective.
- Security is maintained.
In short, various signatures of repeated transactions are the result of EVM’s ability to replace “Scripubkeys”, which balances sequence, efficiency and safety.
