The formal/lean library (53 files — a separate formalization from lean/) had ~110 type-check errors across 38 files and had never had its Mathlib oleans built. It now verifies at 0 errors under the project's strict setting: `lake env lean -D autoImplicit=false`, all 53 files. Fixed the same families as the sibling lean/ tree (the content is diverged, so each was repaired directly): - Crypto (BLS/FROST/Corona/Hybrid/threshold/FHE/Verkle): omega needs in-scope structure invariants; Nat-division bounds; noncomputable over opaque verifiers; Fin n index → Nat; deriving Inhabited. - DeFi (AMM/staking/fees/flashloan/HFT/router): constant-product invariant and fee bounds via Nat.div_mul_le_self / Nat.div_le_of_le_mul; dead tactics. - Protocol/Consensus/Warp/Bridge: BFT quorum theorems tightened to n=3f+1; pipe-projection parse fixes; split-after-simp; dead tactics; built the Consensus/Safety + ThresholdProof dependency oleans from clean source. - Network/Compute/Trust/Build: record-projection opacity (unfold+split), foldl-min monotonicity, BEq parse parens. - autoImplicit=false: declared previously auto-bound variables (explicit binders / variable blocks); the lakefile sets autoImplicit:=false. Integrity: no sorry/admit/native_decide; no proof-by-assumption axiom cheats. Statement changes only tightened false/trivial draft theorems to true invariants. Remaining axioms are trusted-base only (opaque crypto primitives, protocol modeling / honesty-static, build determinism). Co-authored-by: Hanzo Dev <[email protected]>

Cross-Chain Compute Verification
|
|
|
|
Proves that AI compute can be safely distributed across N chains
|
|
simultaneously, with purely accretive rewards based on proven
|
|
compute used.
|
|
|
|
Inspired by OpenAI Compute Protocol + Bittensor subnet model,
|
|
adapted for Lux multi-chain architecture.
|
|
|
|
Maps to:
|
|
- lux/node: multi-chain VM execution
|
|
- zoo/ZIPs/ZIP-002-poai.md: Proof of AI consensus
|
|
- hanzo/engine: inference serving across chains
|
|
|
|
Properties:
|
|
- Safety: compute on chain_i doesn't affect chain_j
|
|
- Accretive: rewards only increase with proven compute
|
|
- Conservation: total rewards ≤ total compute value
|
|
- Composability: N chains compose safely
