Taifoon

A trustless cross-chain synchronization layer for generating, storing, and synchronizing cryptographic proofs across L1/L2/L3 networks — with minute-fresh Gas & Price oracles, a permissionless runner network, and predictable PROOF/SYNC products.

Why Taifoon

Cross-chain apps keep hitting the same walls:

• Volatile gas → missed windows or 2–5× overpayment
• Opaque runner economics → unpredictable unit costs
• Bespoke proof/execution stacks → fragile ops, hard to audit

Taifoon makes it boring (in the best way): quote → prove → execute, all trustlessly generated, stored on-chain, and synchronized with reproducible invoices.

Products

Oracles (Retail)

• Gas Oracle (per chain): low, sensible, max, halt
• Price Oracle (per asset / quote in ETH or USDC): current, sensible, low, halt
• Minute buckets + adjustable windows using percentiles + EWMA guard
• Quotes are reconstructable from on-chain storage (snapshot IDs)

PROOF

• Integrates Polymer proof schemas
• Stores commitments + metadata on the Taifoon L3 (Arbitrum Orbit)
• Anyone can verify and re-derive costs from oracle snapshots

SYNC

• Deterministic execution on destination chains from proved events
• Modes: Ad-hoc (per event) or Cadence (batch every N minutes)
• Default sensible costing, auto-upgrade to max for urgent / first-X

Design Philosophy

• Trustless by default — generate, store, and synchronize proofs on-chain
• Predictable costs — minute snapshots bind quotes to invoices
• Asynchronous everywhere — decouple observation (event) from action (execution)
• Open participation — Runner DAO; per-chain specialization encouraged

Prior Art & Positioning

Some niche systems (e.g., Polkadot) attach cross-domain logic to onBlockFinalize to trigger actions. That's workable intra-domain, but brittle across heterogeneous chains and finality models.

Taifoon uses a network-wide asynchronous subscription model: apps subscribe to events; runners produce proofs; executions are scheduled independently. EVM lacks a native, fair, de-duplicated cross-domain execution primitive — Taifoon fills the gap with a verifiable queue and the Golden Winner puzzle game.
