🌉P2P Token Bridge Using Blue Guava Signaling

⚡ Zero-Trust Crosschain Value Transfer Protocol

The piARM P2P Bridge is a non-custodial, trust-minimized protocol for cross-chain value transfer — with no wrapped tokens, no relayers-as-a-service, and no custodial multisigs.

It leverages the Blue Guava coordination engine and distributed piARM Relay Nodes to verify and transmit cryptographic proofs directly between participants. The result is a bridgeless, peer-to-peer swap protocol — optionally privacy-enhanced — with full cold wallet compatibility.

🔁 Core Workflow: Token Swap Across Chains

🧩 Step-by-Step Flow (Alice → Bob)

1. Session Initiation

   • Alice and Bob agree to a trade across Chain A and Chain B (e.g., $100 USDC on Base ↔ 500 DAI on Optimism).

   • A Guava Session ID is generated, either via wallet interface or a CLI command.

   • Both parties sign an ephemeral key pair used for signaling.

2. Escrow Lock on Chain A (Alice)

   • Alice creates an on-chain escrow smart contract lock on Chain A.

     • Token: USDC

     • Amount: 100

     • Conditions: Valid until expiry timestamp or challenge/fallback condition.

     • A hash commitment is made using Guava’s message format.

3. Proof of Lock → Guava Signal

   • Once Alice’s escrow is confirmed on-chain, a Blue Guava Signal is emitted:

     • Contains Merkle proof of lock

     • Session ID

     • Alice’s wallet ID

     • Timeout fallback

   • The signal is relayed peer-to-peer or through distributed PiRelays.

4. Claim on Chain B (Bob)

   • Bob verifies the signal and mints or transfers DAI to Alice (500 DAI).

   • This is either:

     • A pre-funded vault model, or

     • Bob escrows a matching commitment on Chain B (symmetric settlement).

   • Once transfer is made, Bob emits a Guava Receipt Signal with proof of action.

5. Finalization on Chain A

   • Alice receives the Guava receipt.

   • The original escrow on Chain A is finalized, either:

     • Burned (if synthetic/mirror token was used), or

     • Released back to Alice (if trade was voided), or

     • Sent to Bob (if confirmed swap occurred).

🔐 Privacy Layer (Future development)

The P2P Bridge supports privacy-preserving features:

• Encrypted Session Metadata Ephemeral keys obscure participant addresses, amounts, and timestamps.

• Route Obfuscation via piARM relays Signals can be routed through randomized relay nodes to mask origin chains.

• Cold-Signed Payloads Sensitive instructions can be signed offline and broadcast via trusted peers.

This allows users to execute fully-private, off-chain coordinated swaps — ideal for OTC, DAO treasuries, or activist funds escaping surveillance-heavy chains.

🛰️ Relay Node Economy

piARM Relays are deterministic message routers — not chain indexers, oracles, or validators. They forward signed Guava Signals and earn micro-fees for:

• Verifying messages (escrow → receipt → finalize)

• Rebroadcasting orphaned/missed messages

• Arbitrating expired or challenged sessions

🛠️ Relay Design:

• Stateless and lightweight

• Language: Rust or Go

• Rewarded in native gas tokens or piARM tokens

• Optional integration for privacy and high availability

This enables a modular, distributed relay economy — similar to Helium or Pocket, but purpose-built for peer coordination, not bandwidth or RPC.

🧪 Use Cases

• Private OTC Swaps — Direct, trustless settlement across chains

• Bridgeless Exits — Escape chains like Base or Optimism into Pulsechain, Fantom, etc.

• Multi-hop Routing — Relay through third parties (A → C via B)

• Contract Integrations — DApps can settle remote chain logic without liquidity pools

🔒 Security & Trust Design

Component	Mechanism
❌ No Central Server	Signaling is peer-to-peer or via decentralized relays
🔐 No Custody	All tokens locked in on-chain contracts, not in bridges
🧾 Verifiable Proofs	Chain A/B events proven via hash commitment + signature trees
⏱️ Timeouts	Escrow auto-voids after expiry or incomplete confirmation
💥 Dispute Recovery	Fallback logic allows user to reclaim funds with signed receipt

• Crosschain OTC: Bob and Alice coordinate a private swap across incompatible chains.

• Bridgeless Escapes: Exit Base or Optimism into chains like Fantom or Pulsechain without bridging delays or risks.

• Multi-hop Trades: Relay swaps through intermediate chains via multi-party sessions.

• DApp Integrations: Protocols can use the bridge to settle transactions across chains without liquidity pools.
