Re: [ANN][CLAM] CLAMs, Proof-Of-Chain, Proof-Of-Working-Stake, a.k.a. "Clamcoin"

I've registered an identity on testnet using CLAMour as follows:

The tx c82f27a509bf2c04ffb037f683d8259894f273f8d8f849a8e0545879d5444a2c has CLAMspeech

The text at the link is "Testnet identity 039df70c1c46425ae4d3be53892949e17bebcbe30f419132441faab92677b220f5 (address mr1yhbGu64c83LtN5GBxPVPBb7XheNi8rH)".

The "identity" can (in a sense) be looked up using the client:

Code:

cct getclamour 1a762d25
{
"pid" : "1a762d25",
"hash" : "1a762d2507760a436061029547245e434fa89da6e9d22cf07d6f8a6140b31f37",
"url" : "http://txti.es/1a762d25",
"txid" : "c82f27a509bf2c04ffb037f683d8259894f273f8d8f849a8e0545879d5444a2c",
"confirmations" : 16
}

While this would work, I think it's better to separate it from CLAMour. Also, I think I shouldn't say "identity" when what I really mean is "pubkey". Here's an alternative approach:

The tx 6c08736d725217eeaf04dd3e1cc90ee17123f4361b7318fd9f68b02d87823b0b has CLAMspeech

register pubkey 8b8070fe 039df70c1c46425ae4d3be53892949e17bebcbe30f419132441faab92677b220f5

Here the hex "8b8070fe" is the 4 byte checksum of the corresponding address: mr1yhbGu64c83LtN5GBxPVPBb7XheNi8rH.

A "getpubkey" command (like "getclamour") would be helpful.

Thoughts?

I'm not sure why you need to use any URL. The register pubkey 8b8070fe 039df70c1c46425ae4d3be53892949e17bebcbe30f419132441faab92677b220f5 one seems easiest. But the checksum is only valid for Bitcoin testnet. So unless you specify either "Bitcoin testnet" or "111" (i.e. Bitcoin testnet prefix byte), it would take 112 iterations of sha256d to verify the checksum, assuming the verifier starts at prefix_byte = 0. That's not a heavy burden, but it seems unnecessary.
