Portable Cryptographic Authorship and Multi-Proof Artifact Bundles
Continuum now supports complete end-to-end signed artifact bundles containing Nostr, PGP, Bitcoin, and SSH proofs alongside manifests and signer metadata. The verifier flow locally recomputes the artifact hash and validates every attached proof against the same artifact, allowing independently verifiable multi-proof attestations without relying on relays, cloud services, or centralized platforms. The article explores how portable cryptographic artifact bundles, multi-party attestations, and composite signing authorities could fundamentally change digital authorship and verification.
