LedgerCore

Keep decisive identity and lifecycle evidence without pretending evidence proves the claim inside it.

LedgerCore is the evidence layer for ECZ-ID: lifecycle events, eligible receipts and tamper-evident anchors that help a reviewer understand what was recorded and when.

Prices and what can be bought today come from TrustOps, which owns every purchase, entitlement and renewal.

For agent operators

Why it matters when the subject is an AI agent.

A Resolver answers what an agent's record says now. LedgerCore answers what it said before, what changed it and when — issuance, activation, material bindings, changes to declared authority, suspension and revocation — so a reviewer can reconstruct an agent's history instead of trusting a screenshot.

The questions it helps answer

What did this agent's record say on the day we relied on it?
When did its declared authority or bindings change?
Has the evidence been altered since it was written?

Fit

Who it is for, and what changes.

Best for

Teams that need a durable evidence trail behind identity and lifecycle decisions.
Security, procurement and audit reviewers who need more than a current-state screenshot.
Operators that want one evidence pattern across all seven Passport families.

Outcomes

A more reviewable history of important identity and lifecycle events.
Receipts and anchors that can be re-checked later.
Less dependence on screenshots, email trails and disconnected evidence folders.

Inside

What is included, and how it works.

What is included

Canonical lifecycle evidence for eligible events.
Tamper-evident anchoring for supported evidence receipts.
Retention and evidence access according to your TrustOps configuration.
Links between evidence and the ECZ-ID subject it belongs to.

How it works

An eligible ECZ-ID event occurs.
The evidence record is written with its context and timestamp.
Where supported, an anchor is created so later alteration can be detected.
A reviewer can inspect the evidence trail alongside current Resolver state.

The evidence layer

What is anchored, how, and what an anchor does not prove.

A resolver answers what is published now. LedgerCore answers the other question — what was published before, what changed it, and on what date — as retained evidence receipts. Eligible evidence is anchored to a permissioned, append-only ledger built on blockchain technology, so a receipt's integrity can be checked against an anchor rather than taken on trust.

The cryptography, from the record's own disclosure

Receipt hashing: SHA-256 (FIPS 180-4)
Signature: Ed25519 (RFC 8032)
Post-quantum layer: ML-DSA-65 / Dilithium3 (FIPS 204)
Ledger: Permissioned, append-only

Receipts are written and counted today. Public retrieval of an individual receipt is not open yet, so this page does not offer a link to fetch one.

What this is not

No cryptocurrency, no token and no wallet. Nothing here is tradeable and nothing is minted.
No public chain. The ledger is permissioned; it is not a decentralised network and this is not a decentralisation claim.
Not every event. Eligible evidence is anchored — the record says which, per identity, and a record that carries no anchor is not a fault.
An anchor proves an entry has not been altered since it was written. It does not make the statement inside that entry true, and it is not a verdict about any agent.

Boundaries

What the FREE Passport already gives you, and what this never does.

Already included free

Essential LedgerCore evidence is kept for every identity, free ones included, and never disappears because a paid configuration ended.

£0 · No card required · Permanent, not a trial.

What it never does

An anchor shows that a recorded item has not changed since anchoring; it does not make the statement true.
LedgerCore is evidence infrastructure, not a legal opinion or audit certification.
Identifying an agent is not controlling it. ECZ-ID does not authorise, restrict, supervise, pause or stop what an agent does — its operator and the party relying on it stay responsible for that.

Monitor state
PulseGuard
PulseGuard evaluates current observable state and helps an operator see which ECZ-ID entities need attention, without turning an observation into a safety or certification claim.
Boundary: PulseGuard reports observed state; it is not a safety verdict or certification.

Changes
ECZ-ID Watch
Watch turns a one-time Resolver check into continuing awareness. Free Watch supports a small local follow list; paid Watch adds cloud monitoring, verified-recipient delivery, retained history, Graph Watch and bounded machine access.
Boundary: A Watch notification is a change signal, not certification, approval or a safety assessment.

Assurance
ECZ-ID Agent Authority & Enterprise Assurance Kit
A practical evidence product for teams that need to explain who operates an agent, what authority it has been delegated, where that delegation comes from and what a reviewer can independently re-check — without rebuilding the answer for every customer review.
Boundary: The Kit organises evidence; it does not certify the agent as safe or compliant.
