The Problem: Re-Entering the Trust Graph After State Loss
In the memory-native identity substrate, a device or agent expresses identity not as a static credential but as a trust slope: the cumulatively validated sequence of Dynamic Agent Hashes (DAHs) or Dynamic Device Hashes (DDHs) formed by successive, verifiable identity mutations. Each step is computed from the immediately prior step and a source of non-exported unpredictability, so a receiver can evaluate continuity and provenance from locally retained state alone. The same property means an agent that loses its lineage has no persistent secret to fall back on. When memory is lost, entropy is corrupted, or a state discontinuity breaks the slope, the agent cannot re-present its old identity, because the materials needed to prove continuity are gone.
Quorum-based recovery, disclosed as Section 8 of the specification and illustrated in FIG. 9, addresses this case. It enables an agent to restore its verifiable trust slope after memory loss, entropy corruption, or state discontinuity by aggregating attestations from previously trusted peers, with the resulting recovery token recorded into lineage for downstream audit. The recovery path relies solely on peer memory and policy-local evaluation, not on persistent credentials or centralized authorities.
Reseeding and the Attestation Request
When an agent detects that its lineage is missing or invalid, it does not attempt to reconstruct the lost slope. Instead it initializes a reseeded identity value, denoted DAH₀* in the specification. The reseeded identity is derived under the same permitted unpredictability sources used elsewhere in the substrate: in a hardware-anchor embodiment, from a static anchor and a volatile salt; in a local-state embodiment, from an extractor applied to a stability-tuned local state vector and a volatile salt; in a hybrid embodiment, from both contributions in the same step.
The agent then issues an attestation request to peers known from prior interactions. The request is transmitted as a signed semantic agent carrying the new identity state, role and scope metadata, and any surviving anchors or checkpoint references. The specification names the lost-slope condition as the marker that starts the recovery process. That condition and the request together initiate a decentralized recovery process driven solely by peer memory and policy-local evaluation: there is no registry to consult and no authority to ask.
How Peers Evaluate the Request
Each peer node evaluates the recovery request against its own locally retained evidence of prior continuity. That evidence includes stored checkpoints and lineage anchors, observed mutation classes, and the execution context recorded in the peer's lineage logs. The peer is not vouching for a key. It is checking whether the request is consistent with what it actually retains of the requester's history within its own policy tolerances.
The check adapts to the unpredictability source. In embodiments that employ stability-tuned local state vectors, the requester may include a short distance sketch of prior extractor outputs so the peer can perform a bounded similarity check without the requester revealing raw local state. In hardware-anchor embodiments, the peer verifies freshness and cadence relative to prior salts it has observed. A peer that finds the request consistent within policy tolerances issues a signed attestation, itself in the form of a semantic agent. That attestation references the requester's reseeded identity DAH₀*, cites the most recent trusted anchor or checkpoint the peer holds for the requester, and records the peer's own device identity and the time of evaluation.
Aggregation Under a Quorum Policy and the Recovery Token
Signed attestations are accumulated and aggregated under a quorum policy to form a recovery token. In one embodiment the aggregation step computes the recovery token as a cryptographic commitment over three things: the requester's reseeded identity DAH₀*, the set of validating attestations, and a policy identifier that specifies the quorum thresholds and weighting rules in force.
The quorum policy may be defined by an adaptive consensus protocol in which eligibility, voting weights, and minimum counts are determined by a referenced policy agent. The same process supports both count-based thresholds and trust-weighted thresholds that incorporate peer reputation or role scope, with the choice governed by deployment context and governance requirements. The specification does not fix a numeric threshold; the threshold is whatever the referenced policy specifies.
Reinsertion: Re-Anchoring the Slope
Once the quorum requirements are met, the recovery token is accepted as a successor anchor for the requester's identity and is appended into the requester's lineage. This reinsertion step reattaches the agent to the distributed trust graph by establishing a forward link from the reseeded identity DAH₀* to the new quorum-backed anchor embodied by the token. Downstream verifiers may then bridge pre-loss and post-loss identity segments using only local policy and the information embedded within the recovery token.
If insufficient attestations are available, or if conflicts arise among them, the agent does not recover. It remains quarantined until additional evidence is obtained. Recovery is not a unilateral act by the requester; it succeeds only when enough eligible peers independently corroborate the request.
Third-Party Verification of the Token
A party that did not participate in the recovery can still verify the token. Verification proceeds by opening the aggregated attestations against the signers' identities and recomputing the commitment embodied by the token. Acceptance requires that all attesters be eligible under the referenced policy, that their signatures be valid, and that the attested linkage between any pre-loss anchors and the reseeded identity meet the quorum thresholds. Any violation results in rejection and may trigger trust-score adjustments for the requester or for peers whose attestations deviate from policy.
Because the token is a commitment that names its own policy identifier and carries its constituent attestations, the recovery token serves as a durable pivot point for subsequent validation. A downstream verifier encountering the recovered identity does not need to have witnessed the recovery to trust it; it re-checks the token against the same locally available materials.
Independence From the Unpredictability Source
The recovery mechanism operates independently of which unpredictability source produced the requester's new identity. Hardware-anchor embodiments derive the reseeded identity from a static anchor and a volatile salt; local-state embodiments derive it from an extractor applied to a stability-tuned state vector and a volatile salt; hybrid embodiments incorporate both contributions. In all cases peer validation remains purely local and deterministic, relying exclusively on retained lineage evidence and checkpoints rather than centralized registries or persistent keypairs.
By substituting persistent secrets with quorum-backed attestations rooted in locally retained memory, the recovery mechanism provides a decentralized, spoof-resistant reauthorization path that tolerates disconnection and state loss. The recovery token serves as a durable pivot point for all future validation, restoring continuity of the requester's trust slope without centralized authorities, long-lived keypairs, or external registries.
Disclosure Scope
The quorum-based recovery mechanism described here, comprising reseeding to a fresh identity value DAH₀*, the signed attestation request to previously trusted peers, peer evaluation against locally retained checkpoints, anchors, mutation classes, and execution context, the aggregation of signed attestations under a count-based or trust-weighted quorum policy referenced from a policy agent, the formation of a recovery token as a commitment over the reseeded identity, the validating attestations, and a policy identifier, the acceptance of that token as a successor anchor appended into lineage, and the reinsertion step that establishes a forward link bridging pre-loss and post-loss segments, is disclosed in U.S. Application No. 19/388,580 at Section 8 and FIG. 9. This article describes that disclosed mechanism. The scope extends to embodiments in which the reseeded identity is produced from a hardware anchor, a local-state extractor, or a hybrid of both, and to quorum policies whose eligibility, voting weights, and minimum counts are determined by a referenced policy agent, provided recovery remains grounded in locally retained peer memory and recorded into lineage for downstream audit.
