How It Works

From integration to defensible recovery, in five steps.

EpositBox slots alongside your existing stack. You keep your applications and your cloud — we hold the data that has to stay defensible.

  1. 01

    Blockchain-Enhanced Security

    Sensitive values land in an immutable, decentralized custody layer with automatic backups and versioning.

  2. 02

    Risk & Overhead Transfer

    EpositBox acts as a third-party custodian, mitigating liability and reducing the operational burden of protecting regulated data.

  3. 03

    Machine-to-Machine Access

    A REST API authenticated by mutual TLS. No human users on the data path. Service identity policies on every call.

  4. 04

    Version Control & Recovery

    Every update produces a new block. Prior iterations stay intact, indexed, and recoverable in seconds.

  5. 05

    Granular Access + Full Audit Trail

    Reads, writes, and deletes are permanently logged with timestamps, identity, and context.

Integration in practice

A familiar API. An uncommon level of proof.

A typical write looks like any modern REST call — but every operation is signed, attested, and permanently logged.

POST /v1/records
Host: api.epositbox.com
Content-Type: application/json
# Mutual TLS — service identity verified at the edge

{
  "tenant": "acme-bank",
  "schema": "kyc.v3",
  "payload": { /* sensitive values */ }
}

200 OK
{
  "pointer": "epb://acme-bank/kyc.v3/01HZX...",
  "version": 1,
  "audit_id": "aud_01HZX...",
  "ts": "2026-01-12T09:14:22Z"
}
