Error Report Analysis: Bitcoin Node Rejects Non -Analyzed Signs Signature 2/3 Multisig script
In the field of cryptocurrency, Multisig and Timelock scripts have appeared as stable security measures to protect user funds. The latest development is related to the reaction of the Bitcoin network (BTC) to a certain type of multisig script. In this article, we will go into the details of the question, influenced and possible in possible solutions.
Background: 2/3 multisig script with timelock
The 2/3 multisig script is a sophisticated program that combines multiple signatures (two out of three) to authorize transactions on the Bitcoin network. This type of script requires special syntax to provide valid signatures. To add Timelock functionality, which allows automated removal after a certain period, the administrator can create a multi -signature script with a timelock position.
Multisig script looks like this:
`bash
1/3; 2/3;
2/3;
3/3;
`
This script has three signatures: 1 from 3 for 2/3 (administrator), 2 of 3 for 3/3 (user), and the third signature is not required (unsigned user).
Error Message: Noranyized Dir Signature
Bitcoin node returns the error code -26 with the following message:
`
Mandatory script-terified-flag-nominitis
`
This error is due to the signature of the script der (outstanding coding rules) does not meet the canonical requirements. In canonical mode, all signatures must be in a certain format, which allows you to verify effectively.
What’s wrong?
Multisig scripts in the context of Timelock are the question when the node tries to check the signatories’ permits without ensuring that their signatures are correctly formatted in accordance with the canonical rules. In particular, there is an error “Non -Banonic Signature” because:
1
Derivating path : The script derivative path may not be correctly indicated or configured, leading to incorrect signature format.
- Signer ID : Some signatories (such as non -signatures users) may have a different ID structure than expected, causing the verification process.
Solutions and solutions
To resolve this question:
- Check the derivation paths : Double -check all script knots to make sure they are properly defined.
- Adjust the signator’s ID : If the user acts as an unsymptomed entity, update their ID structure according to the canonical valid requirements.
3
Check signature formats : Check that all signatures are in the correct format (for example, x509v3 format) and are properly encoded.
Conclusion
Error -26 with the message” Mandatory-Scrypt-Verify-Flag-Filed “is a critical problem if you use 2/3 multisig scripts with Timelock functionality on the Bitcoin network. By understanding what causes this problem, you can introduce the necessary fixes to solve the problem. Remember that canonical suitable signatures are important for effective testing and it is important to ensure that they are properly formatted.
suggestion
When introducing or modifying a multisig script with Timelock, make sure:
- Check the derivation paths.
- Adjust the signatorial ID if necessary (for example, non -signatures users).
- Check signature formats according to canonical requirements.
By doing this, you will be able to avoid this error and enjoy a safe and reliable experience on the Bitcoin network.
