1 2015-05-17 07:02:37 <rebroad> hmmm. any developers on here?
 2 2015-05-17 07:03:17 <rebroad> I might have identified a vulnerability in bitcoin, probably haven't, but just in case, better if I can PM someone who understands the protocol
 3 2015-05-17 07:16:12 <gmaxwell> rebroad: I'm around-ish.
 4 2015-05-17 07:16:31 <gmaxwell> You can also send email to any of us privately (GPG if serious).
 5 2015-05-17 15:45:27 <cjd> hey hey...   2015-05-17 15:42:39 ERROR: AcceptToMemoryPool : nonstandard transaction: non-final  <-- so what backward compat did you guys break this time xD
 6 2015-05-17 15:52:48 <cjd> is that the old nLockTime thing?
 7 2015-05-17 16:47:27 <b-itcoinssg> if I wanted to verify a block, do I  sha256(contatinate(previous block hash,nonce)) and check whether the result is lesser than target difficulty?
 8 2015-05-17 16:48:32 <b-itcoinssg> do the previous block hash and nonce have to be in binary/hex/or something else?
 9 2015-05-17 16:52:08 <adlai> sha256 is run twice in a row. the hashed data is https://en.bitcoin.it/wiki/Protocol_documentation#Block_Headers and to properly verify it, you also need to process all the preceeding blocks, and all their transactions
