AVALANCHE EVIDENCE ANCHORING · LIVE

Public integrity layer + private evidence + portable artifact + PQ verification.

H33's Avalanche story is not "we anchored 32 bytes." It is end-to-end provenance: a public chain commitment to a private off-chain bundle that anyone can verify independently, with no H33 contact required, using a downloadable Apache 2.0 verifier built from a reproducible recipe.

The four layers

PENDING AUTHORIZATION

Layer 1 · Public Integrity

Avalanche mainnet anchor

Single on-chain tx commits the SHA3-384 of the off-chain bundle. Anyone can fetch the tx from any Avalanche RPC and compare. Awaits four-field-paste founder authorization.

LIVE (PREVIEW-SIGNED)

Layer 2 · Private Evidence

Off-chain bundle

Self-contained JSON. Authority + policy + pipeline + model + corpus + evidence + citations + abstention bind into one signed artifact. Today: preview-grade signatures. Post-R1 ceremony: production PQ signatures from R1 root.

LIVE

Layer 3 · Portable Artifact

Verifier runs offline

Apache 2.0 verifier downloadable from h33.ai/downloads/. Reproducible build (rust-toolchain.toml + Cargo.lock + SOURCE_DATE_EPOCH=0). Byte-identical across two independent runs.

PARTIAL (R4 PENDING)

Layer 4 · PQ Verification

Envelope on delivery

ML-DSA + SLH-DSA signatures on the bundle (R1). PQ envelope on API delivery (R4 ceremony pending). Replay-detectable at envelope granularity; integrity-detectable at bundle granularity.

Mainnet anchor state

When founder authorization lands, the four placeholder values below are replaced with the real on-chain transaction details. The off-chain bundle's _preview_metadata.anchor_ref is updated; chain-aware verifiers add public-integrity verdict to their output.

tx_hash:: 0x0000000000000000000000000000000000000000000000000000000000000000 (pending)
manifest_anchor_ref:: 0x0000000000000000000000000000000000000000000000000000000000000000 (pending)
customer_principal:: PLACEHOLDER_PRINCIPAL (pending)
anchored_at_ns:: 0 (pending)

Founder four-field paste is held under terminal-directives lock 2026-06-06. When authorized, this section migrates to live values within minutes.

Try it now

The off-chain bundle verifies independently against the live published binary today. After mainnet anchor authorization, the same command output adds an on-chain match line.

Why this matters

Anchoring 32 bytes on a public chain is not a moat — every chain offers it. What is differentiated is the COMPOSITION: a publicly-anchored commitment to a privately-signed off-chain bundle, where the bundle is portable across systems, verifiable without contacting the issuer, and PQ-future-proofed for the lifetime of the underlying asset. That composition is what makes H33 evidence acceptable to issuers, custodians, regulators, and auditors simultaneously.
