Every AI output is now a potential exhibit.
LangSmith traces and Datadog logs don't survive cross-examination. A Sealed Evidence Record does: SHA-256 Merkle root Sigstore anchor chain of custody.
Seal one yourself, in-browser, no install:

Yesterday we anchored a legal fact into a public transparency log that can never be edited.
Cost: $0. Time: 10 seconds. Verifiable by anyone, forever.
Here is why this matters for every AI agent that touches real money π§΅

This is not a mockup. Seal a fact yourself right now β in your browser, no install, no signup:
verdict.systems/live-seal
You get a real entry in a public transparency log, with a verify link anyone can check independently.

AI agents are about to act on real capital at scale. The companies that can PROVE what their agents did will win the audits, the lawsuits, and the insurance pricing.
We are building that evidence layer in public.
Follow @VerdictSys to watch it happen.

Your agents are in production.
Your logs are not evidence.
The deployer is the defendant.
(N.D. Cal., April 14, 2026)
That ruling is 57 days old.
How many of your tool calls are sealed?

Three forces colliding:
β ISO CG 40 47/48 live Jan 1 β 82% of US P&C carriers writing AI exclusions
β 97M MCP installs as of March 2026
β EU Product Liability Directive: December 9, 2026
Insurers are pricing the risk faster than enterprises are building the evidence.

Every tool call. Every model decision. Every policy gate.
Hash-chained. Merkle-rooted. Rekor-anchored.
Court-admissible under FRE 902(14).
That's what Verdict seals.

Most AI audit trails are logs a developer can edit.
Evidence is different: signed, hash-chained, anchored to a public transparency log.

This week I talked to builders working on:
β Agent identity (who is this agent)
β Agent coordination (how they communicate)
β Agent execution (what they actually do)
Every single one of them needs the same missing piece: proof of what happened.
That's not a coincidence. The accountability layer is the last thing everyone builds and the first thing everyone needs when something goes wrong.
Building that layer at verdict.systems.

Anthropic, June 4: the AI industry "has a gas pedal but no brake pedal."
A brake works only if everyone can verify the rules.
Agents now take real actions with no tamper-evident record of what they did or who approved it.
That's the layer we're building. verdict.systems

Most "AI evidence" tools ask you to trust them.
We just shipped the opposite.
Paste a Sealed Evidence Record at verdict.systems/verify β cryptographic green check.
Change one byte β it goes red and tells you exactly which check failed.
Runs 100% in your browser. The record never touches our server.
Don't trust us. Verify.

The whole point of a cryptographic seal: you shouldn't have to trust the sealer.
/verify re-derives the payload hash, the record commitment, and the evidence ID from the record itself β in your browser, offline.
Same engine runs in our Rust edge crate as an MCP tool Claude can call. Byte-for-byte identical.

We shipped /live-seal as a "demo."
Paste any fact β tamper-evident Sigstore Rekor anchor in your browser. No install. No signup.
It quietly became our highest-converting page.
Skeptics don't believe pitches. They believe proofs.

Who needs this yesterday:
β Anyone building agents
β Anyone using them
β Insurance
β Legal
Common thread: every decision they make gets audited eventually.
Without proof, scrutiny becomes liability.

Every AI output is now a potential exhibit.
LangSmith, Datadog, Sentry β none of it survives a Daubert challenge.
Verdict is the evidence layer. SHA-256. Merkle root. Sigstore anchor. FRE 902(14).
