Blockchain Validated Asset Metadata (BVAM)

Blockchain Validated Asset Metadata (BVAM) is a method which allows Counterparty Token metadata to be stored off-blockchain yet still be verifiable and inalterable.

http://xcp.ninja is a proof of concept server for creating and storing BVAM json files.

Example BVAM json, http://xcp.ninja/hash/TB2rTB5FdLtqYu31wTmKgy54TYeZSqJgr3.json
