Bitcoin: Why are the results of BTC message signature implemented in Python different from those on electrum?

Understand the implementation of the signature of Bitcoin Message: Comparison Python and Electric

Bitcoin’s decentralized and over the book is a built on a complex cryptographic syntem, largely relying on safe encoding tracts. In this article, we will give the differences between .

Background: Bitcoin Message Signature

Wen sende on the Bitcoin network, the miners we . To achieve that, they a public key associated with each private in ther ther walet. This procer involves spraying a message (transactions) with a private kying a SHA-256 and that coded it to the sender.

Implementation in Python: bit

In Python, Bitcoin’s Cryptograph Library (Bit) provides a simple and safe to handle private private private. Thekey ‘object is a private key in the WIF format, that functionVerify_sig takes hash and signature as an entry and the check.

`Python

from the Key to import

WIF_PRIVE_KEY = 'KXB19KFRRQRMT79BVG4TNKGPIBVCGPACVJKVJKP1IBGJNH39QG'

Create a new privatekey ubject with WIF private key

Private_KEY = Key.from_wif (Wif_private_KEY)

Get the sender's public address using a private key

Public_address = Private_KEY.GET_PUBLIC ()

Hash transaction with a private Key and get a signature

Transaction_hash = Private_KEY.hash_transation (Public_address, 0.0001)

Signature = Private_KEY.SIGN (transaction_hash)

Check signature against hash

result = VERIFY_SIG (Private_key, transaction_hash, signature)

Print (result)



Implementation in Electric: ECDSA

In contrast, the implementation of the Electrian wallet iss the algorithm of This library provides a safer and more effactive to handle private keys and signatures.

Python

from the Key to import

WIF_PRIVE_KEY = 'KXB19KFRRQRMT79BVG4TNKGPIBVCGPACVJKVJKP1IBGJNH39QG'


Create a new privatekey ubject with WIF private key

Private_KEY = Key.from_wif (Wif_private_KEY)


Get the sender's public address using a private key

Public_address = Private_KEY.GET_PUBLIC ()


Hash transaction with a private Key and get a signature

Transaction_hash = Private_KEY.hash_transation (Public_address, 0.0001)

Signature = Private_KEY.SIGN (transaction_hash)


Check the signature against hash

result = VERIFY_SIG (Private_key, transaction_hash, signature)

Print (result)

`

differences in results

After billing both implementation with the same WIF private Key and identical transactions, we can dom of soar deviations:

  • The result of implementationbitprint a different message about an error or exception to implementation.

  • Generalally, the implementation of “Electrom’s” can produce more cryptic outputs or warnings related to eliptic curves.

  • Some differences in generalated code and error removal information will be occur due to variations between and ECDSA implementation.

In conclusion, it is the both implication of the similar goals, the results of the signature of Bitcoin messages are performed different to Wallet. Understanding the difference is crucia for a safe and reliable of the cryptocurrency.
