Since I don’t know the context and details of your issue, I can’t provide you with an article that explains how to create or resolve a specific error in Bitcoin.
However, I can provide general guidance on how to approach this issue.
The error message “Signature must be null for failed CHECK(MULTI)SIG operation” indicates that there is a problem with how you are handling signatures in your Bitcoin transaction. Here are some steps you can take to troubleshoot and resolve the issue:
- Review your code: Take a close look at your code and make sure that signing transactions, including signature generation, are handled correctly.
- Check for typos or formatting issues
: Make sure that there are no typos or formatting errors in your code that could be causing the issue.
- Verify correct use of cryptographic functions
: Make sure you are using the correct cryptographic functions (e.g.
ecdsa_sign,ecdsa_verify) and calling them correctly with the appropriate parameters.
- Test with different data structures: As you mentioned, trying different data structures can help you identify any issues that may be causing the problem.
Regarding the data structures used in Bitcoin transactions, some common ones include:
struct transaction
struct payment
struct message
If you are using a specific data structure for your Bitcoin transactions, I recommend checking the [Bitcoin documentation] ( for details on how to encode and decode each component of a transaction.
You may also want to seek advice from other developers or experts in the field who have experience working with Bitcoin.
