Hello again,

I've rework= ed this idea a bit as alluded to previously.=C2=A0 The key highlights of Nu= merifides are now:

- Transaction is a normal trans= action paying to a script hash with a CHECKSEQUENCEVERIFY encumbrance.
- Users "mine" their registrations to produce TXIDs with Pr= oof of Work attached (providing for a way to secure and "commandeer&qu= ot; names).
- Secondary network for gossiping name->data mappi= ngs, that is rooted from the numerifide transactions on the Bitcoin blockch= ain.

The "mining" is done simply by incr= ementing a nonce in the registration data (off-chain).=C2=A0 This prevents = "namesquatting" like we see on Namecoin.

There is an easy formula that uses the Timelock, Proof of Work and amount = of Bitcoin locked that determines which transactions are authoritative for = a given name mapping.


Feedback and c= riticism appreciated,
Tyler

Greetings,

= I have been working on a proposal called Numerifides which would provide a = general method to register human-readable names and arbitrary data (such as= username->GPG key, domain->IP address, Lightning node Alias-> URI= , etc).=C2=A0 Here are the key highlights:

--New transaction type called "numerifides" transactions<= /div>
--Lock up Bitcoin fo= r a certain amount of time to make the mappings valid, discourage "nam= esquatting"
--T= ransaction puzzle attached to transactions to allow community consensus rev= ocation of highly contested names or "squatted" name mappings.
--Transactions are RBF= so if name is contentious or miners wish to censor, one honest greedy mine= r can include the censored user's high-fee transaction)
--Solves Zooko's triangle of Se= cure, Decentralized and Human Meaningful

Full working spec is here:=C2=A0https://github.com/tyzbit/numerifides

I'd love feedback and possible = enhancements, as I know this early rough draft does have a lot of room for = improvement (I also think it would be remiss to incentivize filling blocks = with data like this, and a possible change proposed on the lightning-dev li= st by=C2=A0ZmnSCPxj is a P2WSH defining the mapping that is gossiped about = outside of the Bitcoin network, but I'd like to hear all comments).

Thank you for your time.
