A comprehensive framework for creating self-contained provenance packages with multi-ledger time evidence, verifiable entirely offline without network connectivity or institutional infrastructure.
Existing provenance systems fail when network connectivity is unavailable or institutional infrastructure collapses. Eternity Layer solves this.
Complete verification on air-gapped systems without any network access. Deterministic accept/reject decisions regardless of connectivity.
Time evidence anchored to Bitcoin, Ethereum, and Arweave. Composite Finality Score (CFS) aggregates trust across independent ledgers.
Self-contained Eternity Packages (EP) bundle content, signatures, and proof bundles into a single portable artifact.
EL-C14N-v2 ensures byte-identical representations across implementations, eliminating verification ambiguity.
EL-DID provides decentralized identifiers with full-root resolution, independent of any central authority.
Sub-cent anchoring costs at scale without protocol tokens. Verifiable service receipts enable sustainable operation.

18 interoperable specifications covering canonicalization, packaging, anchoring, identity, and verification.
Peer-reviewed research with fully reproducible implementations and open-access archives.
