Many of today’s NFTs are not designed to endure. Kanon brings museological best practices for the documentation and preservation of digitally based art on-chain through KSPEC, Kanon’s open-source protocol. KSPEC extends the ERC-721 NFT standard to allow for complex artworks, their provenance, their curatorial context, and the artist’s identity and intent to be preserved indefinitely and transparently. K21 will be the first KSPEC compliant NFT collection.
