Whitepaper Highlights
What the Nexus whitepaper covers.
Execution lanes, predictable liquidity, governance cadence, and programmatic guardrails — the building blocks of the SORA v3 economy.
Architecture
Lanes, Merge Ledger & Data Spaces
Sections 6–7 explain how Nexus scales with parallel lanes while the merge ledger keeps one canonical order across sovereign data spaces.
- Lanes finalize independently and fuse or split deterministically based on load.
- Merge ledger orders lane tips without rewriting finalized history.
- Data spaces provide privacy and jurisdictional controls while still emitting proofs.

Execution
IVM, Kotodama & Deterministic Contracts
Sections 5 and 11 detail the Iroha Virtual Machine and Kotodama bytecode that keep Nexus execution deterministic.
- Pointer-ABI defines typed handles so contracts cannot craft malformed references.
- Gas tables and syscalls are versioned on-chain for predictable execution.
- Kotodama bytecode (.to) plus Norito serialization keeps auditing and ZK tracing straightforward.

Security & DA
FASTPQ Proofs, DA Sampling & Sumeragi
Sections 8–10 describe the Sumeragi pipeline, Start-Time Fair Queuing, and FASTPQ zk-STARK proofs tied to DA certificates.
- Sumeragi finalizes non-empty slots in ~1 s with deterministic leader rotation.
- FASTPQ proofs aggregate per-data-space execution into verifiable lane receipts.
- Two-dimensional erasure coding plus DA sampling keeps data recoverable and auditable.

Governance
SORA Parliament & Governance Surfaces
Sections 7.2 and 16 outline configuration surfaces, data-space onboarding, and the upcoming SORA Parliament structure.
- Council, Assembly, and Technical Committee publish Norito manifests with XOR bonds.
- Parameter sets (crypto, scheduling, admission caps) are versioned on-chain.
- New data spaces require attested certificates; unknown DSIDs are rejected.
