How it works
AI says it. REEcord proves it.
01 — The Problem
AI outputs cannot be proven.
AI is now behind critical decisions — legal analysis, financial reports, medical recommendations. But there is a fundamental gap: no one can prove that a given output was actually produced by a specific model, at a specific time, in response to a specific prompt. Screenshots can be faked. Logs can be deleted. Timestamps can be manipulated. As long as AI outputs remain unverifiable, accountability is impossible.
Who said it? Which model? When exactly? Was it altered? Can it be audited?
02 — The Technology
Gensyn's Reproducible Execution Environment
Gensyn built REE — a deterministic environment that runs AI inference and produces a cryptographic receipt for every execution. The same model, the same prompt, always produces the same verifiable output. This makes AI execution mathematically provable — not just claimed.
03 — The Bridge
REEcord seals the proof on-chain
We take Gensyn's cryptographic receipt and anchor it permanently to the blockchain. The receipt hash and IPFS content identifier are written to a smart contract on Gensyn Testnet — immutable, public, and globally verifiable. Anyone with a transaction hash can independently confirm exactly what was said, by which model, and when.
04 — The Interface
One click to record. Anyone can verify.
REEcord makes this entire pipeline accessible through a simple interface. Chat with any supported AI model locally — your data never leaves your machine. When you're ready, hit Finalize & Record. The system handles REE execution, IPFS upload, and on-chain submission automatically. Every recorded conversation appears publicly on reecord.click, verifiable by anyone in the world with just a transaction hash — no wallet required to verify.
05 — Under the Hood
What happens when you record
STEP 01

Local AI conversation

You chat with an AI model running locally via Ollama. No data is sent to external servers. The full conversation is stored locally and persists across sessions.

STEP 02

REE execution

The full conversation is formatted and passed to Gensyn's REE inside a Docker container. REE loads the exact same model and processes the prompt deterministically, producing a receipt.json with a cryptographic signature.

STEP 03

Encryption & IPFS upload

The receipt is encrypted using AES-256-GCM derived from your wallet key — only you can decrypt it. The encrypted file is pinned to IPFS via Pinata, returning a content identifier (CID).

STEP 04

On-chain submission

The receipt hash, IPFS CID, model name, and your wallet address are written to the ReceiptRegistry smart contract on Gensyn Testnet. A transaction hash is generated — this is your permanent, tamper-proof proof of record.

STEP 05

Public verification

Anyone can enter the transaction hash on reecord.click to verify the record on-chain. Wallet owners can connect to decrypt and view the full conversation content. The proof is immutable and lives on the blockchain permanently.
