Sovereignty that survives the owner. PLENA's receipt grammar is designed to make Bitcoin holdings transmissible to family, counsel, or institutions across decades — without holding keys, holding coins, or replacing any custodian.
Industry reporting in 2026 has framed Bitcoin inheritance as a structural gap: families often have no familiarity with private key operations, and material losses have occurred when the only person who understood a setup became unavailable. The readiness question is no longer "how big is your stack" but "does your system still work when you do not." PLENA's role is not custody — established custodians serve that function — but the human-accountable proof archive that surrounds custody: who is authorized, who has reviewed, what the recoverable access plan is, and how a family member or attorney can verify it.
Workflow 1
The authority structure around the keys — never the keys themselves.
A CONSERVA + SIGILLA receipt recording who is authorized to receive what, when, and under what conditions. Not the keys themselves — the authority structure around the keys.
A sealed PLENA receipt describing the recovery pathway in plain language, witnessed by a named human reviewer (clergy, attorney, family elder, trusted counsel), held in multi-archive preservation.
The existing Proof Yearbook architecture extended to an annual Bitcoin readiness review — confirmation that the plan still works, refreshed annually, with refusal logic if any element has degraded.
A SIGILLA-sealed, multi-language packet for the eventual beneficiaries, designed to be opened only on specified conditions, with PLENA's existing Public Verify available for the beneficiary to confirm authenticity.
Workflow 2
A human-accountable record around (not instead of) the custodian's controls.
For SOC 1, SOC 2, and proof-of-reserves audits — recording who performed the audit, what was refused, and what was corrected. PlenaProof complements these audits; it does not replace SOC 1, SOC 2, or any audit standard.
For multi-institution custody models, a PLENA receipt structure that aggregates attestations from each participating custodian into a single auditable record.
For Layer-2 bridges and wrapped-Bitcoin operations — human authorization records that survive after the transaction.
For individual Bitcoin holders preparing inheritance readiness, and for institutional custodians designing named-attestation workflows: PlenaProof welcomes pilot conversations.
