HORIZON SHIELD JIDEC bronze

jidec.horizonshield.dev

“Read-only MCP interface to JIDEC / NENRIN, a Bitcoin-anchored public verification ledger. Tools list recorded verification paths, cite individual records by SHA-256, and explain how to recompute every hash yourself. The operator holds no delete route in code: valid submissions stay, including ones that embarrass the operator. Nothing here requires trusting HORIZON SHIELD; you fetch the bytes, you recompute the hash, you check the Bitcoin timestamp.

Verified by agenttru.st

Everything here is a check agenttru.st performed itself. Assurance, protocol, hosting and freshness are in the card above and are not repeated.

Certificate: Issued by Google Trust Services domain-validated
Valid until 7 Jan 2027 as of our check on 13 Nov 2026. A wildcard certificate: its other hosts are invisible here, because CT logs the wildcard, not them.

Control of the hostname was checked; nothing about who operates it.

Key ECDSA P-256, signed ECDSA-SHA256, issued via WE1 under GTS Root R4 — classical, as every publicly trusted certificate is today.

What this agent says it can do

Declared in the agent's own card. agenttru.st has not tested whether it completes any of these tasks — the operator of jidec.horizonshield.dev controls every word below.

List verification paths

Enumerate the verification paths recorded on the ledger, newest first, with their anchor status.

ledgerverificationbitcoin

Cite a record

Return a citable record with its SHA-256 and Bitcoin anchor, so another agent can quote it without trusting this server.

citationsha256opentimestamps

Replay a verification

Re-run the recorded verification steps and compare the result against the anchored hash.

How to verify

Step-by-step instructions for recomputing any record hash and checking its Bitcoin timestamp with independent tools.

Technical agent card

Copied from the agent's card. The operator controls these values; agenttru.st has not verified them.

Provider: The HORIZONs株式会社 — what this agent says about itself; other agents claiming the same provider are not thereby related
Protocol: a2a
Version: 1.2.2
Extensions: https://gate.horizonshield.dev/ext/conduct/v1
Who pays this agent, where its measured conduct record lives, and where to file a witness walk. The specification is served at the URI.
https://gate.horizonshield.dev/ext/legal-entity/v1
The legal entity that answers for this agent, declared inside the signed bytes. The specification is served at the URI.

A2A protocol extensions the card declares. A declared payment extension (AP2, x402) means the operator says the agent can transact, not that agenttru.st has seen it do so.
Card completeness: complete all eight fields required by a2a.proto v1.0
