🗒️ Summary of this message: A revised proposal for addressing bugs in the spec includes defining network class, network, and data class using bits.
📝 Original message:Some bugs I found in my spec so far:
- Bitcoin public keys begin with '2' (same as testnet data)
- For the first first-class "aux" network, signatures and private keys will
start with the same character.
- More "collisions" are possible if the "reserved" values were ever assigned.
To address these slightly better, here's a revised proposal:
* Bits 128/64 define network class
** 0 = main network
** 64,128 = reserved
** 192 = test network
* Bits 32/16 define network
** 0 = Bitcoin
** 16,32 = reserved
** 48 = OTHER (next octet)
* Bits 8/4/2 define data class
** 0 = Public key hash
** 2 = reserved
** 4 = Script hash
** 6 = Public key (raw)
** 8 = Signature
** 10 = reserved
** 12 = Private key (raw)
** 14 = OTHER (next octet)
* Bit 1 is freely chosen (for aesthetic assignment)
Note that under this scheme, both script hashes and raw public keys begin with
'3'; I consider this a non-issue since neither are supported by current-
generation clients, and both pubkey-hash and script-hash are quite capable of
the same functionality as a raw public key. Also, the raw public key will
presumably be noticably longer.
