Ethereum: Decoding ScriptSig
Decoding the mystery of the script signatures
In cryptography, the script is a sequence of transactions that are broadcast and signed by the pages involved. One type of script used in Ethereum known as “Scriptsig” contains a signature for each transaction in it. However, after decoding, the intentions of these signatures can be unclear.
What does Scriptsig do signatures exhaustive?
Signature of the script was created using the following components:
–
hash transactions
: hexadecimal presentation of the input transaction.
–
Data bytes
: variable length 0x01 bytes, which are used to design the script (digital amount) and add data to it.
The secret of many signatures
Skryptsig may have more than one signature, which may seem like a mistake or error. However, this is not obligatory. The reason for these “many” signatures is that Ethereum stores transactions.
After creating a transaction, it is signed by its inputs (data that will be used to design the script script). These signature values are then combined with transaction input data and stored as the value of the scripts in Blockchain. In most cases, there may be only one signature for the transaction.
Why do we need a lot of signatures?
Many signatures allow several reasons:
–
Verification of the transaction : having a signature of each of his input data, Ethereum ensures that at least one transaction in one transaction (ie below one script) is checked and accepted.
–
Prevention twice : If the transaction had to be issued twice in the same installment, it will create two identical transactions. This prevents many signatures, guaranteeing independent check of each transaction.
What does the script have a lot of signatures?
In general, when you see “many signatures” or “more than one signature” in connection with the values of the script, this usually means that they are part of a larger transaction in which two separate transactions have the same input but require independent Checking.
Decorate and check such transactions in Ethereum:
–
Check the transaction cut : Make sure it’s correct.
–
Check SkrypThash : Check that each signature value corresponds to the appropriate input.
–
Check a lot of signatures : If you see more than one signature, make sure they come from different input data and have been properly connected.
App
In summary, although at first glance it may seem complicated, signatures on the Ethereum script serve for a specific purpose. Many signatures are the result of Blockchain architecture, ensuring that transactions are checked regardless of many pages. By understanding these complexities, you can better understand Ethereum transactions and scripts, even if they look mysterious at the beginning.
