Changelog

​

Week of May 18, 2026

​

New features

​

Reineira settlement loop

• New PayoutClaimer resolver contract on Arbitrum Sepolia handles claim submission and disbursement.
• InferenceGate and ResultRegistry updated to plug into the settlement path.
• ICL exposes settlement-aware quorum and chain services so the coordinator can drive payouts end-to-end.

​

Confidential escrow primitive

• New escrow scripts make it straightforward to create and fund an escrow for a task.
• The IConfidentialEscrow interface defines the standard contract shape for resolvers that gate payouts on inference results.

​

Text inference wizard

​

Updates

• ICL internal API — the coordinator’s internal router gained new endpoints for driving the settlement loop and surfacing claim state, so node operators and integrators can observe payouts in flight.
• End-to-end test coverage — a full E2E test now exercises encrypt → submit → quorum → settlement → claim in one run, so regressions in the settlement path get caught before release.
• Result commitment hardening — ResultRegistry now exposes a stable interface (IResultRegistry) for resolvers and downstream contracts to consume, making it easier to build custom payout logic on top of verified results.

​

Bug fixes

• Inference API client — fixed a missing field in the text inference request payload that could cause the wizard to stall before submission.
• Chain service — result registry calls now use the updated commitment shape end-to-end; nodes no longer hit decode errors when reading recent results.

​

Wave 4 — Previous Release

​

Major Changes

​

1. NodeRegistry Contract (Arbitrum Sepolia)

• register(tier, attestationHash, expiresAt, models) — node self-registration with optional stake
• heartbeat() — on-chain liveness proof
• isActive(node) — checks attestation expiry + heartbeat recency
• updateAttestation(...) — ICL can update a node’s attestation hash/tier
• withdrawStake() — node can exit and reclaim stake

​

2. Interactive Attestation CLI

Attestation type:
  [1] Mock (development)
  [2] TEE / TPM (production)
Select [1]:

• Option 1: Mock attestation with weloveblindference
• Option 2: TEE/TPM — explains hardware requirements, offers dev TEE simulation with custom key

​

3. Blindference-Node PyPI Package

• Published as blindference-node on PyPI (v0.3.0+)
• Auto-publish workflow: tags v* trigger GitHub Actions → PyPI
• Supports both bridge mode (TypeScript CoFHE subprocess) and python mode (direct HTTP)
• Auto-re-attestation: nodes self-heal on startup and via watchdog (no manual intervention)
• Configuration-driven: single BLINDFERENCE_NODE_CONFIG_PATH JSON file controls all behavior

​

2. Professional Documentation Site

• Compute section (8 pages): Node operator quickstart, installation, configuration, attestation, running, monitoring, troubleshooting, rewards
• Build section (9 pages + 2 examples): Agent developer quickstart, architecture, CoFHE encryption, ICL API, contracts, deployment, risk-scoring example, text-inference example
• API Reference: Full ICL REST API documentation
• Resources: Changelog, contract addresses, troubleshooting
• Dark Blindference theme (#0d0d0d background, white/zinc-400 accents)
• Auto-validation CI: checks mint.json navigation, page existence, logo paths, broken links

​

3. Full Quorum Test Passed

• ICL selected leader + 2 verifiers correctly
• All 3 nodes received task assignments and claimed successfully
• Nodes processed through CoFHE decrypt → IPFS fetch → inference pipeline
• ICL bugs discovered and fixed during live quorum testing

​

4. ICL Production Hardening

• In-memory DB operators: _matches() now supports $or, $in, $eq, $ne, $gt, $gte, $lt, $lte
• Assignment dispatch: _get_pending_assignments() returns task_id (not request_id)
• Pydantic compatibility: get_assignments() uses getattr() for model field access
• Hex handle parsing: claim_task() parses 0x-prefixed handles with int(val, 16)
• MongoDB Atlas persistence: USE_MONGO=true with fallback to in-memory when unavailable
• HEARTBEAT_GRACE_SECONDS: 300: ICL can restart without losing active nodes (was 3600)

​

5. Branding Cleanup

• wave2_network/ → network/ (all path references updated)
• Wave3Popup.tsx → ProtocolUpdatePopup.tsx
• WAVE2_SUBMISSION.md → SUBMISSION.md
• fhenix-fhe.md → FHE_INTEGRATION.md
• LLM_CONTEXT.md → CONTEXT.md
• No “Wave 2”, “Wave 3”, “wave2”, “wave3” references remain in source or docs

​

Contract Deployments (Arbitrum Sepolia)

​

Bug Fixes

• ICL in-memory DB: Full MongoDB operator support ($or, $in, $eq, $ne, $gt, $gte, $lt, $lte)
• Assignment dispatch: _get_pending_assignments() returns task_id for correct node lookups
• Pydantic model handling: get_assignments() uses getattr() instead of .get() on Pydantic objects
• Hex handle parsing: claim_task handles 0x-prefixed hex strings with int(val, 16)
• ICL quorum preview: Returns proper leader/verifier addresses when operators are active
• Node CoFHE default: get_cofhe_client() defaults to CoFHEBridgeClient, mock mode fully removed
• Frontend mock removal: MockCoFHEClient class deleted, all code paths use real CoFHE
• Vite optimizeDeps: Only tfhe excluded; @cofhe/sdk pre-bundled for CJS interop
• TFHE WASM: Absolute path /node_modules/tfhe/tfhe_bg.wasm?url survives cache invalidation

​

Technical Decisions

• NodeRegistry contract: Unified registration replaces NodeAttestationRegistry + NodeOperatorRegistry combo
• On-chain heartbeat every 10 days: Minimal gas while still providing objective liveness to external contracts
• ICL heartbeat every 60s: Free REST call keeps node eligible for real-time job dispatch
• blindference-node PyPI package: standalone distribution for operator onboarding
• Mintlify over Docusaurus: better dark mode default, built-in search, modern components
• Docs split into Compute (node operators) and Build (agent developers): two distinct audiences
• HEARTBEAT_GRACE_SECONDS: 300: balances ICL restart resilience vs stale-node detection
• Node CoFHE mode bridge (TypeScript subprocess) is default; python (direct HTTP) is alternative
• fheKeyStorage: null prevents stale IndexedDB cache serialization errors
• environment: 'MOCK' on chain config: local ZK proof verification only (ciphertexts are real FHE)

​

Wave 3 — CoFHE SDK Alignment & Text Inference

​

Major Changes

​

1. Confidential Text Inference Pipeline

• Browser-side AES-256 encryption: User prompts encrypted locally before leaving device
• Pinata/IPFS blob storage: Encrypted prompts stored off-chain, only ciphertext handles on-chain
• CoFHE key access control: AES key split into uint128 halves, each half CoFHE-encrypted and stored in PromptKeyStore
• Quorum decryption: Leader + 2 verifiers each receive CoFHE sharing permits to decrypt their key half
• Model inference: Nodes run identical inference via Groq Llama 3 or Google Gemini
• Output key escrow: Leader stores output AES key in PromptKeyStore for user-only decryption
• Frontend reveal: User decrypts output key via CoFHE and reveals generated text

​

2. CoFHE SDK Alignment

• fheKeyStorage: null in SDK config to prevent stale IndexedDB cache serialization errors
• environment: 'MOCK' on chain config enables local ZK proof verification (ciphertexts are real FHE)
• useWorkers: false — ZK proof generation runs on main thread (Web Workers broken in Vite dev)
• Absolute WASM URL path /node_modules/tfhe/tfhe_bg.wasm?url survives cache invalidation
• Vite optimizeDeps excludes only tfhe, pre-bundles @cofhe/sdk normally for CJS interop

​

3. Node Auto-Re-Attestation

• Auto-detect missing/expired attestation certificates on startup
• Automatically re-attest via ICL challenge/response
• Watchdog re-attests within 6 hours of expiry
• No CLI flag needed — default behavior

​

4. ICL Persistence and Resilience

• MongoDB Atlas integration for persistent operator records
• HEARTBEAT_GRACE_SECONDS: 300 (5 min) — ICL can restart without losing active nodes
• In-memory fallback when MongoDB unavailable (local development)
• Fixed in-memory database query operators ($or, $in, array membership)

​

5. Professional Documentation

• Removed all “Wave 2” / “Wave 3” branding from code and documentation
• Renamed wave2_network/ monorepo directory to network/
• Comprehensive README, ARCHITECTURE.md, DEPLOYMENT.md
• Mintlify docs site with Compute and Build sections

​

Contract Deployments (Arbitrum Sepolia)

​

Bug Fixes

• ICL in-memory DB: _matches() now supports MongoDB operators ($or, $in, $eq, $ne, $gt, $gte, $lt, $lte) and array membership queries
• Assignment dispatch: _get_pending_assignments() returns task_id (not request_id) so node lookups succeed
• Pydantic model handling: get_assignments() uses getattr() for Pydantic models instead of .get() which fails on objects
• Hex handle parsing: claim_task now parses 0x-prefixed hex strings with int(val, 16) instead of int(val)
• ICL quorum preview: Returns proper leader/verifier addresses when operators are active
• Node CoFHE default: get_cofhe_client() defaults to CoFHEBridgeClient, mock mode fully removed
• Frontend mock removal: MockCoFHEClient class deleted, all code paths use real CoFHE
