Yesterday I have fixed some issues in the britcoin challenge.
Your initial nonce-zero was computed with wrapping html tags.
If you used the payload in your scripts, and generated noncezero yourself, your computations would not be accepted.
If you took the noncezero from the challenge you were fine.
Also i fixed some minor issues, like wording and the test vectors in the grfc.
Here the example did not use the uppercase hash.
Sorry for the inconvinience!
