I wrote an article talking about this a few months ago: http://www.mail-archive.com/bitcoin-development@lists.sourceforge.net/msg06466.html http://www.mail-archive.com/bitcoin-development@lists.source... "The difficulty of writing consensus critical code: the SIGHASH_SINGLE bug" Five pages of detail about a single bug^H^H^H feature, and just the other day I found yet another edge case in the implementation that I hadn't noticed before.

I don't believe that you are really Peter Todd, can you please sign the challenge "1" with one of your known bitcoin addresses? Joking aside, I used some of your scripts to seed the fuzzer: https://github.com/jonasnick/bitcoinconsensus_testcases/tree/master/examples https://github.com/jonasnick/bitcoinconsensus_testcases/tree.... If you come up with more scripts I'd love to feed them to the fuzzer. I'm still surprised that a javascript implementation (bitcore) is withstanding so far.
