The 4-Stage Conduit Pipeline

“Comprehensive lifecycle from stealth ingress through zero-knowledge severance to clean egress.”

REVISION: MMXXVI.09.15•MATHEMATICAL SOUNDNESS: FORMAL PROOF•DEPTH 20 MERKLE COMMITMENT

§Architectural Pipeline Overview#

The Vellum Conduit Pipeline is an autonomous, four-stage cryptographic state machine designed to ingest, shield, delay, and settle sovereign value across heterogeneous blockchain environments.

§The Four Sequential Stages#

Stage 01: Stealth Ingress

  • Action: Funds enter via direct contract call or single-use app order address.
  • Trace: Zero ABI function parameters revealing recipient or intention.
  • Escrow: Native assets locked in the sovereign ingress conduit.

    • Stage 02: Arc Commitment

  • Action: Commitment C = Poseidon(r, v, s) inserted into the depth-20 Merkle tree on the Arc Blockchain.
  • Circuit: arc_deposit_v2.circom validates correctness of commitment parameters.
  • Nullifier: Secret key k and nullifier η = Poseidon(k, nullifier\_secret) established off-chain in private witness.

    • Stage 03: Heuristic Evasion

  • Action: Value enters the Poisson arrival buffer.
  • Execution: Liquidity tranche sharding decomposes transactions into non-linear denominations.
  • Result: Complete abolition of chain graph clustering and temporal heuristics.

    • Stage 04: Clean Egress

  • Action: Independent relayer submits Groth16 zk-SNARK proof of inclusion to the destination verifier contract.
  • Payout: Pristine native assets disbursed to the destination recipient.
  • Destruction: Nullifier η permanently registered on-chain, preventing double-spending while revealing zero information about the deposit.
