Aevum & Bond

Dual-ledger thesis

A single chain cannot be simultaneously censorship-resistant and expressively programmable without tradeoffs that neither side accepts. Bitcoin optimises for the first at the cost of the second; every general-purpose smart-contract chain makes the opposite bet.

Aevum & Bond refuses the tradeoff by separating the two goals onto two purpose-built chains bridged by a trust-minimised contract (wBND):

  • Bond RSC — Reserve Settlement Chain. Probabilistic UTXO, proof-of-work, SHA3-256. The signing primitive is ML-DSA (FIPS 204) from genesis. Optimised for censorship-resistant value storage and settlement.

  • Aevum ESC — Execution Settlement Chain. Deterministic BFT, WASM virtual machine (Wasmer Singlepass AOT), native Account Abstraction with Paymaster delegation. Optimised for rich, deterministic, auditable computation.

Both chains share a hybrid post-quantum P2P stack (Noise with ML-KEM-768 + X25519) and a common autonomous on-chain detector for a quantum break (the Quantum Canary).

The remainder of this documentation walks through the mechanism design, proofs, and the hardware signer (Arca) that anchors self-custody in the post-quantum regime.
