Semantic Nonce Attribute Protocol (SNAP)

Generate proof-of-work hashes with semantic meaning

This protocol offers a flexible data structure for ingesting semantic data into a 21e8 proof-of-work hash. It's based on the Magic Attribute Protocol and Bitcoin Schema.

SNAPS are magic data structures, semantic data with a nonce that's used to generate 21e8 proof-of-work hashes.

The SNAP Bitcoin Schema is defined on-chain at (b843b7c73549a6e24b073777b936051f314804e43ef4a243f49407cc562ac9dd). It has the following fields

1. nonce (Integer)
2. Optional: parent (Hash)
3. Optional: namespace (String)
4. Extension: tags (List)

Bitcoin Schema

SNAP is based on Bitcoin Schema and the Magic Attribute Protocol (MAP).

MAP allows flexible key/value data in Bitcoin protocols. Bitcoin Schema allows semantic layers and meaning on top.

Bitcoin Schema

Bitcoin Schema defines a set of key/values for a specific context, identified by a txid.

Parent

Parent refers to a 21e8 parent hash derived from a world key. If there is no parent, this hash becomes a world key.

Namespace

Namespaces are valuable for specific derivation paths or generating UUIDs to avoid hash collisions.

Nonce

Nonce is an integer that gets flipped to generate the 21e8 hash with appropriate proof-of-work.

SELECT

Using MAP SELECT can associate data on other hashes

Extension: tags

Add tags to a proof of work hash.
