Payment Settlement
One settlement record across all parties. No float, no disputes, no end-of-day reconciliation.

The multi-party system of record
One shared state.
Cryptographic proof.
Every multi-party operation spends fortune and headcount reconciling records that should never have disagreed. Every regulator asks the same question: can you prove what happened? Stratum gives every party one shared operational record—the same cryptographically final version of the truth. Arbiter turns that record into assessor-ready evidence for SOC 2 and ISO 27001.

Arbiter is built for SOC 2 and ISO 27001 assessment workflows. BlockSkunk's own assessment program is in progress. We don't claim certification today.
The Problem
Every party keeps a different version of the truth
Every multi-party operation runs on fragmented records. Each institution keeps its own version of who owns what, when it settled, and which rules apply. Entire teams exist just to make those versions agree.
A shared database cannot fix it, because someone has to own the database.
Stratum is the multi-party system of record no single party controls. Arbiter turns that shared record into proof assessors can verify—evidence integrity, not another export folder.
Yesterday 5 versions · 3 weeks
- Five organizations each had their own version of the same shipment
- Reconciliation teams spent weeks making spreadsheets agree
- Three weeks assembling evidence for an ISO assessment
Today 1 record · verify directly
- Every participant sees the same cryptographically verified record
- One shared state—ownership, settlement, and rules in one place
- Your assessor verifies sealed evidence directly

The Block Skunk Thesis
The clearest signal is the one no one can alter.
Most compliance ends with documents. Ours ends with proof. One tamper-evident record. Every party verifies it. Assessors review it directly.
