Bitcoin Evolution: By unpacking OPHECKSIGverify significance **
Bitcoin’s basic technology over the years is large chaangs, and each update is previous. One noticeable example is the addition of Bitcoin Cash (BCH) multi -time operations. In this article, we dive into the OPCKSIGverify OPCODE, which is the Hosen as a Fire operation for multimedia traces and moplasts.
Multisig Operations: Deeper Diving
Multiple surgery is a crocinal deed of cryptocurrency that allows multiple drugs to agree with a veto. The most common implementation is the “disposable” (1-0-1) scheme, WRE on one of the signatures can be justified.
2018 The Bitcoin Cash (BCH) has been improved to include the multimedia operation Core Protocol. This amendment introduced a new OPCODE: op_checkksigverify '.
op_checkksigverify Cause **
OPCOCKSIGverify is not just a simple implementation of OPCOCKSIG; It's actually
Traditional signatures in one country can sign and control its result. This restriction of the inspections of cryptocurrencies that require multilateral evenings associated with general nature. BCH This problem is softened by the introduction of hierarchical identical (HD) symbols to furniture into Create Walts Walts Walts.
OPHECKSIGverify OPCODE is responsible for confirmation this:
- The operation input is a list of the signatories and their respective private keys.
- Each signator sends his or her public key and checks it by one of the signators.
- If the signator's public keys are expected, they may be used privately.
OPCOCKSIGverify vs. Op_checkksig
The OPCOKKSIG OPCODE Allone should only be confirmed by the signatures of only a few signators, regardless of the overall. This leads to a few questions:
ineffective confirmation :
* Security deficiency
: Under no circumstances it provide any maritime nature compared to traditional signatures.
The introduction of the OPCHOCKSIGVERIFY is provided by them by mixing and the effective way to confirm the BCH transactions. Hierarchical determiner Walets, which is OPCKSIGverify opodes.
Conclusion
*
In conclusion, the choice of security and efficiency of BCH value. Understanding this effect, Developers can evaluate innovative feats that earn Bitcoin Castcoin Cash and users.
Code Example: op_checkksigverify
To combine OP_COCKSIGverify together, here's a Python example:
Python
Import Hashlib
Def Verify_Signature (Sister_Public_Key, signature):
Use Securre bag function such as Sha-256
hehed_signature = Heashlib.sha256 (STR (signature) .encode ()). Digest ()
Pull out the signator’s personal key from a public key
Private_Key = sler_public_key.hex ()
Private_bytes = BYS.Fromhamex (Private_Key)
Calculate Exped Signature Use a private key
Waiting_Signature = Hashlib.sha256 (Private_bytes).
