Generation of reception addresses of the P2Wash Multi-Sig
====================================== ==== = ===
As Bitcoin’s understanding and its underlying protocols deepen, it is essential to explore the mechanisms used by wallets to the safe transactions of the facilities. A critical aspect is to generate reception addresses, which are necessary to receive funds from other users.
In this article, we will examine how to generate directorates of a P2Wash Multi-Sig script in Python.
PREVIOUS REQUIREMENTS
——————-
- Familiarity with the basic concepts of Bitcoin and the P2Wash protocol
- A basic understanding of programming concepts
Multiple P2Wash Multiple Script
——————————–
A P2Wash Multi-Sig script is a type of wallet that allows safe multiple signature transactions. Here is an example of how it could be implemented:
`Python
Import hashlibri
Import Bincii
Of IMIT IMPORT BECH32
Define constants for the hash blockchain and the parameters of derivation of the firm
Blockchain_hash = "your_blockchain_hash_here"
Sigderivationparameter = 3
Def derive_signature (p, r, s):
"" "A signature derives using the public key" "
Return (hexlify (p) .decode () + hashlib.sha256 (b "s" .encode ()). Digest (). Hex ()) % 1000000
Def p2wpub_script (p, sig, r, s, n):
"" "Generate the multiple P2Wash Multiple" "" "" "
Return bech32.decode_p2wsh_Script (
f "1. {sig}. {r}. {s}. {n}",
[Hexlify (P) .Decode (), hashlib.sha256 (B "s" .encode ()).
)
Def Main () ::
Derive the public key, the firm and the random number
P = Derive_Signature ("Your_public_Key_here", 0x12, 0x34)
R = Derive_Signature (P, 1, 2)
S = Derive_Signature (R, 3, 4)
N = Derive_Signature (S, 5, 6)
Generate multiple P2Wash script
script = P2WPUB_Script (P, None, R, S, N)
Print the generated script
Print (script.decode ("UTF-8"))
Yes __name__ == "__main__":

GENERATION OF RECEPTION ADDRESSES
----------------------------
A reception address is a unique identifier that can be used to receive funds from other users. In the context of P2Wash, reception addresses are generally derived using a similar process.
TheP2WPUB_Scriptfunction generates a multiple P2Wash script, which includes the public key, the firm, the random number and the non -random parameters (R, S, N). To generate addresses to this script, we need to derive a unique identifier that is not present in the script.
Here is an updated version of the code:
` Python
Import hashlibri
Import Bincii
Define constants for the hash blockchain and the parameters of derivation of the firm
Blockchain_hash = “your_blockchain_hash_here”
Sigderivationparameter = 3
Def derive_signature (p, r, s):
“” “A signature derives using the public key” “
Return (hexlify (p) .decode () + hashlib.sha256 (b “s” .encode ()). Digest (). Hex ()) % 1000000
Def p2wpub_script (p, sig, r, s, n):
“” “Generate the multiple P2Wash Multiple” “” “” “
Return bech32.decode_p2wsh_Script (
f “1. {sig}. {r}. {s}. {n}”,
[Hexlify (P) .Decode (), hashlib.sha256 (B “s” .encode ()).
)
Def derive_receive_address (script, script_hash):
“” “Derive a reception address of the P2Wash Multi-Sig” “” “” “
Remove the non -random parameters (R, S, N) and the hash
R, S, N = Extract_parameters (script)
Derive a unique identifier using SHA-256
Id = Hasiblib.sha256 (R + S + N.encode ()).
Return f “2. {Id.hex () {blockchain_hash}”
Def extract_parameters (script):
“” Extract the non -random parameters (R, S, N) and the hash of the script “” “”
Remove the signature, random number and non -random parameters
R, S = Extract_Signature (script)
Id = Hasiblib.sha256 (R + S.encode ()).
