<p>Andyparkins: Comment on &quot;version&quot; nomenclature</p> <hr /> <div>Personally, I don't like the nomenclature &quot;version&quot;. It's signalling far more than just a version. How about &quot;address class&quot;?<br /> --[[User:Andyparkins|Andyparkins]] 11:49, 9 December 2011 (GMT)</div>

<p>Andyparkins: Comment on non-incremental git commitish workaround</p> <hr /> <div>Just as a point of information; &quot;git describe&quot; output solves the problem of non-incremental committish. It does this by providing a base version code (the most recent tag name) the number of commits past that tag and then a little bit of the commitish for the revision in question.<br /> --[[User:Andyparkins|Andyparkins]] 11:45, 9 December 2011 (GMT)</div>

<p>Andyparkins: Magic numbers are wrong</p> <hr /> <div>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!). -- [[User:X6763|X6763]]<br /> <br /> <br /> Is the checksum in the addr sample correct? Here's what I get using OpenSSL (sorry for long lines):<br /> SHA256(&quot;\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&quot;) = <br /> 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<br /> and SHA256 of that is<br /> 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<br /> It could easily be I'm using OpenSSL incorrectly, so wanted to get confirmation -- [[User:AndyParkins|AndyParkins]]<br /> <br /> <br /> The description for the headers command says &quot;77x?&quot; as the size for the block_headers[] returned. However, the description of the block_header structure is 81 bytes (4+32+32+4+4+4+1). What exactly is returned by the headers command? -- [[User:AndyParkins|AndyParkins]]<br /> <br /> <br /> The given magic numbers are the wrong way around. The magic numbers are little endian 32 bit numbers on the network, so Testnet.Magic = 0xdab5bffa and Prodnet.Magic = 0xd9b4bef9. The two examples are the order they come in from the wire, so at the very least should be shown with spaces between the bytes.<br /> [[User:AndyParkins|AndyParkins]]</div>
