v0.2.0

bitwrap v0.2.0

Client-side ZK proving, EVM deployment, and full Go/JS parity.

New: WASM Prover

• Groth16 proving runs entirely in the browser via WASM
• Load pre-compiled keys from server or compile circuits offline
• Build with make wasm (~4.6MB gzipped)

New: Key Persistence

• -key-dir ./keys persists circuit keys across restarts
• First startup compiles circuits + saves keys; subsequent starts load instantly
• GET /api/vk/{circuit} — export verifying key
• GET /api/vk/{circuit}/solidity — export Solidity verifier contract

New: EVM Deployment

• GET /api/bundle/{template} — download complete Foundry project (contract + verifier + tests + deploy script)
• Remix plugin now deploys both contract and ZK verifier to workspace
• Added "Foundry Bundle" download button to Remix plugin

New: Full Go/JS Parity

• mimc.js — MiMC-BN254 hash (verified against Go)
• merkle.js — fixed-depth binary Merkle tree
• witness-builder.js — witness builders for all 6 circuits
• safemath.js — U256 overflow-checked arithmetic
• model.js — Petri net model with validation
• state.js — state machine execution (fire, enabled, canReach)
• bridge.js — Schema <-> Model conversion

Breaking Changes

• arc/ moved from internal/arc/ — now importable as github.com/stackdump/bitwrap-io/arc
• public/ moved to repo root — CDN path is now @latest/public/
• internal/static/ removed
• NewArcnetService() now takes a keyDir string parameter
