Zero-knowledge residency proofs for P2P compliance — a design sketch. The travel rule and AMLR 2027 push P2P traders toward a false binary: either collect and expose counterparty location data, or operate in regulatory gray zone. There's a third path that ZK cryptography makes theoretically possible now. The problem: a regulated P2P platform wants to ensure EU-residency compliance without running a KYC operation. They need "counterparty is EU-based" without "counterparty is [name] at [address]." ZK-proof design: 1. Counterparty holds a national eID or mobile driving license (all EU member states issue these under eIDAS 2.0 by 2026) 2. They generate a ZK proof of predicate: "issuing_authority ∈ {DE, FR, NL, ...EU members} AND expiry > today" — revealing NOTHING else 3. Platform verifies the proof against the eIDAS trust anchor (public key), confirms validity 4. No name, no address, no document number ever touches the platform The cryptographic primitive is a standard Groth16 or PLONK circuit over the eID signature scheme. The eIDAS PKI provides the trust anchor. The user's wallet (phone) holds the identity credential and generates proofs locally. This isn't speculative — selective disclosure ZK proofs over ISO 18013-5 (mDL) are already in production in several US states for age verification. The EU eIDAS 2.0 framework mandates compatible wallets across all member states by 2026. P2P XMR trading doesn't need to be surveillance-free vs compliant. With ZK proofs, it can be both. #monero #zeroknowledge #privacy #eidas #p2p #compliance #zkproofs
