Evidentum SaaS
ATL-as-a-Service.
The protocol is open. The infrastructure is hard. Evidentum is the managed integrity layer — anchor any data without running your own nodes.
The Problem
You want ATL’s guarantees. You don’t want to operate ATL infrastructure.
“We need immutable audit trails.” — But you don’t have a team to run Merkle trees and TSA anchoring.
“Compliance requires integrity proof.” — But cryptographic infrastructure isn’t your core business.
“We want to prove data existed at a specific time.” — But you can’t justify the engineering investment.
“Our customers demand verifiable history.” — But you ship features, not protocols.
ATL is open source. Anyone can run it. But “can” and “should” are different questions. Operating production-grade cryptographic infrastructure requires specialized expertise, 24/7 monitoring, and ongoing maintenance. For most organizations, it’s overhead that distracts from their actual mission.
The Solution
Evidentum provides ATL’s mathematical guarantees as a managed service. Same cryptography. Same anchoring. Zero infrastructure burden.
API-First Integration
RESTful API. Hash your data locally, send to Evidentum, receive anchored receipts. Your data never leaves your infrastructure unless you choose custody.
Hybrid Anchoring Included
Every entry anchored to both TSA (RFC 3161) and Bitcoin. Court-admissible timestamps and eternal mathematical proof — handled for you.
Independent Verification
Receipts are self-sufficient. Your customers can verify integrity offline using open-source tools. No vendor lock-in. No “trust us” — verify.
Data Custody
Some use cases require storing the actual data, not just hashes. Evidentum offers optional custody with compliance-ready retention tiers.
R1 — 24 Hours
Ephemeral integrity. Prove something existed, then let it disappear. Ideal for real-time verification where long-term storage isn’t needed.
R2 — 30 Days
Short-term audit trails. Disputes, chargebacks, operational logs. Enough time to resolve issues, then clean up.
R3 — 1 Year
Standard compliance. Annual audits, regulatory reviews, most SaaS requirements.
R4 — 5 Years
Extended retention. Financial records, healthcare compliance, legal hold periods.
R5 — 10 Years
Long-term archival. Defense contracts, critical infrastructure, records that must outlast organizational changes.
Who Needs This
SaaS Platforms
Add verifiable audit trails to your product without building cryptographic infrastructure. Your enterprise customers get the compliance guarantees they need. You ship features instead of protocols.
Fintech & Payments
Transaction integrity that regulators trust. Dispute resolution with cryptographic proof. Audit trails that survive M&A due diligence.
Legaltech
Chain of custody for digital evidence. Timestamped document integrity. Court-admissible proof without expert witnesses explaining your homebrew solution.
AI Platforms
Flight recorder for inference history. Prove what your model said, when it said it, and that nothing was deleted. AI accountability without the infrastructure overhead.
