I'm adding some hexdumps of messages and data structures and descriptions of how these are interpreted in order to help others understand these protocol and data structures. It's a bit redundant, so any ideas as to how to remove some of the redundancy while keeping the knowledge accessible are welcome (feel free to make the changes yourself!). -- X6763

Is the checksum in the addr sample correct? Here's what I get using OpenSSL (sorry for long lines): SHA256("\x01\xe2\x15\x10\x4d\x01\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\xff\xff\x0a\x00\x00\x01\x20\x8d") = d6 88 65 c8 20 61 d5 e2 54 52 b5 5b 52 17 98 b1 11 50 85 96 2e 49 e8 fd da b7 f4 fb a3 9c d8 2c and SHA256 of that is ed 52 39 9b 56 8e d8 d5 9a 83 72 9c 11 6f 87 d0 be f2 84 e9 98 f3 47 7c 98 61 16 9a b1 2e ed 5c ... I have a similar fault in the tx sample, but one at a time ;-) It could easily be I'm using OpenSSL incorrectly, so wanted to get confirmation -- AndyParkins
