Following the discussion that happened around tyzbit’s proposal on advertising lightning nodes via DNS records, he followed up with a proposal that aims to provide human readable, secure and decentralized “names” and arbitrary data on the blockchain while solving Zook’s DCS triangle

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).

Here are the key highlights:

• New transaction type called “numerifides” transactions
• Lock up Bitcoin for a certain amount of time to make the mappings valid, discourage “namesquatting”
• Transaction puzzle attached to transactions to allow community consensus revocation of highly contested names or “squatted” name mappings.
• Transactions are RBF so if name is contentious or miners wish to censor, one honest greedy miner can include the censored user’s high-fee transaction)
• Solves Zooko’s triangle of Secure, Decentralized and Human Meaningful

Greg Slepak posted a link to a paper called the DCS Theorem. It’s a probability proof of the DCS Triangle showing that decentralized consensus systems can have Decentralization, Consensus, or Scale, but not all three simultaneously.

He said on bitcoin-dev said:

The DCS Triangle was independently discovered by myself and Trent McConaghy.

It is a useful tool for clearing confusion about blockchain scalability and blocksize-related debates.

The DCS Theorem is a probability proof of the triangle, and it’s now on arXiv:
