Bitcoin Auth Diagnostics FAQs

Question 1

Does this skill support the BRC77 standard?

Accepted Answer

Yes, it fully supports both the legacy BSM (Bitcoin Signed Message) scheme and the currently recommended BRC77 standard for bitcoin-auth tokens.

Question 2

Why is time skew a common issue in authentication?

Accepted Answer

Tokens typically have a default 'timePad' of 5 minutes; if the client or server clocks are out of sync, or the token is re-used too late, verification will fail to prevent replay attacks.

Question 3

What is the bitcoin-auth token format?

Accepted Answer

Tokens are five-part pipe-delimited strings containing the public key, scheme (bsm or brc77), ISO8601 timestamp, request path, and base64-encoded signature.

Question 4

Can I use this for Sigma Auth integration?

Accepted Answer

Absolutely. This skill includes specific diagnostic steps for Sigma Auth patterns, including wallet connection flows and token-for-endpoint verification.

Question 5

How do I fix 'invalid signature' errors in bitcoin-auth?

Accepted Answer

Common fixes include checking for exact request path matches (including query parameters), ensuring body hash encoding (utf8/hex/base64) is consistent, and verifying the correct scheme is being used.
