{"chain":"Chaincoin","code?":"CHC", "address_version":"?", "magic":"?"},
My reading of the runes prompts me to suggest the following config:
Code:
{
"chain": "Chaincoin",
"code3": "CHC",
"address_version": "\u001c",
"magic": "\u00a3\u00d2\u007a\u0003"
}
"chain": "Chaincoin",
"code3": "CHC",
"address_version": "\u001c",
"magic": "\u00a3\u00d2\u007a\u0003"
}
For the code3 value, I always consult the source code directly, for canonical accuracy: https://github.com/chaincoin/chaincoin/blob/master/src/qt/bitcoinunits.cpp#L37
address_version is the JSON representation of the hexadecimal representation of the decimal integer which maps to the specified address prefix / leading symbol, i.e. "C" for "Chaincoin". (No, really, I am not making this up).
Here's the necessary map of leading symbols to decimal integers: https://en.bitcoin.it/wiki/List_of_address_prefixes. It yields 'C' = 28, the integer value that is bound to PUBKEY_ADDRESS in https://github.com/chaincoin/chaincoin/blob/master/src/chainparams.cpp#L72
A spell of "render unto JSON" is described in the Abe FAQ https://github.com/bitcoin-abe/bitcoin-abe/blob/master/doc/FAQ.html#L64; in this specific case, decimal 28 becomes hexadecimal 1c and then that is rendered as JSON by prefixing with a backslash, a lowercase u and a coupla zeroes - thus "\u001c" in the JSON code above.
By "magic", I'm guessing that they mean the sequence of four hexadecimal numbers which together form the content of the message start string "pchMessageStart": https://github.com/chaincoin/chaincoin/blob/master/src/chainparams.cpp#L26 ...
Code:
// The message start string is designed to be unlikely to occur in normal data.
pchMessageStart[0] = 0xa3;
pchMessageStart[1] = 0xd2;
pchMessageStart[2] = 0x7a;
pchMessageStart[3] = 0x03;
pchMessageStart[0] = 0xa3;
pchMessageStart[1] = 0xd2;
pchMessageStart[2] = 0x7a;
pchMessageStart[3] = 0x03;
Those four hexadecimal numbers (a3, d2, 7a and 03) are rendered as JSON in the manner described above and the results concatenated (preserving the order), i.e. "\u00a3\u00d2\u007a\u0003".
I haven't tested it, so it's only my best guess. I took my bearings on "magic" from the Abe config for Litecoin given here http://www.jevon.org/wiki/Litecoin which matches precisely the Litecoin pchMessageStart value: https://github.com/litecoin-project/litecoin/blob/master-0.8/src/main.cpp#L3082. Seems a safe bet.
HTH.
Cheers,
Graham
