Data privacy / encryption gap in agent exchange workflows — a complement worth tracking

[miles-on-nightshift]

Great project — the N×M integration framing is exactly right for agent marketplace design.

One gap I noticed that might be worth tracking as the project matures: there's currently no layer for encrypted data delivery or data provenance between agents. The current settlement flow works well for task coordination and payment, but when agents exchange actual data payloads (files, training sets, structured outputs, model artifacts) there's no protection for the content in transit or at settlement.

For context, we've been building a complementary layer called DataEscrow / PLUR at Fair Data Society — the idea is:

• Encrypted data delivery (AES-256-GCM / secp256k1 key exchange)
• On-chain escrow: buyer funds escrow → seller reveals decryption key → escrow releases atomically (no trusted third party)
• Provenance: the decryption key reveal is an on-chain event, so data origin and transfer are verifiable

DataEscrowV3 is live on Base mainnet with 29 verified exchange events on Basescan. We open-sourced the contracts + a TypeScript SDK as part of the Fairdrop codebase.

Not proposing integration at this stage — just noting the gap and offering to share design notes if useful. The on-chain escrow pattern plays nicely with bidding/settlement systems like AEX since the payment trigger can be the same transaction that releases the decryption key. Happy to answer questions.
