+# Frostgate: A Modular Architecture for Trustless Interoperability
+
+Frostgate proposes a new architecture for cross-chain interoperability—one that does **not** rely on light clients, centralized bridges, or multisig committees. Instead, it offers a **modular, verifiable system** for message passing across blockchains, primarily grounded in **cryptographic soundness** and **composable design**.
+
+At its core, Frostgate fuses **Succinct State Validation (SSV)**, **zero-knowledge proofs**, and **chain abstraction** into a fully programmable and extensible interoperability stack. Any chain, proving system, or application can adopt it—without compromising decentralization.
+
+
+## Modular by Construction
+
+Frostgate breaks interoperability down into well-defined and composable components:
+
+### 1. ICAP (Interoperable Chain Abstraction Protocol)
+
+ICAP defines how `ChainAdapters` expose chain-specific logic to Frostgate. It abstracts the key components of participating chains, including:
+
+* Finality rules (e.g., Ethereum’s FFG, BEEFY, Solana’s voting)
+* Event log formats
+* Message encoding and decoding
+* Chain-specific light validation (without relying on state replays or full nodes)
+
+Adapters implement a shared trait `ChainAdapter` and output a unified `FrostMessage` structure. This allows new chains to be supported independently by communities—not centralized bridge operators.
+
+
+### 2. ZKPlug: Frostgate’s zk-Agnostic Backend Interface
+
+Frostgate isn’t tied to a single proving system. The `ZKPlug` trait defines how zero-knowledge backends:
+
+* Load and compile circuits
+* Generate state proofs from messages
+* Verify proofs succinctly on-chain
+
+The current implementation integrates **SP1 zkVM**, but the design supports **pluggable backends** like **RiscZero**, **Halo2**, or **Groth16** with minimal overhead. Chains or apps can select backends based on their:
+
+* Trust model
+* Performance
+* Cost
+
+This design enables broad ecosystem flexibility.
+
+
+## Message Flow: How Data Moves Trustlessly
+
+Here’s how Frostgate handles cross-chain event propagation:
+
+1. **Emit:** A finalized event occurs on Chain A and is processed by a `ChainAdapter`.
+2. **Normalize:** The adapter converts the event into a standardized `FrostMessage`.
+3. **Prove:** A prover bundles messages and generates a succinct zk-proof attesting to correctness.
+4. **Relay:** A relayer submits the proof and batch to the target chain (Chain B).
+5. **Verify:** A smart contract on Chain B verifies the zk-proof and processes the message.
+
+Since zk-proofs are computationally expensive, Frostgate uses **batch proofs** to aggregate multiple messages into a single succinct proof.
+
+All actors are **stateless**. All trust assumptions are **cryptographically based**—no chain replication, no state replays, and no multisig committees.
+
+
+## Security Without Multisigs
+
+Multisigs introduce:
+
+* Centralization
+* Failure points
+* Governance complexity
+
+Frostgate bypasses this entirely by:
+
+* Relying on native chain finality (via adapter enforcement)
+* Leveraging zk-proof soundness for message correctness
+* Using proving key attestation to prevent circuit forgery
+* Enabling proof-level replay protection via **batch nonces** and **timestamps**
+
+This means Frostgate’s security scales with the **source chain’s consensus**, not with off-chain signers.
+
+
+## Governance and Registry Design
+
+Frostgate’s modularity allows anyone to implement new components to extend functionality. However, **trustless interoperability needs standards**—so Frostgate introduces a **Registry Layer**.
+
+In our design, **anyone** can submit a new adapter or zk backend. But each submission must be **verification-gated**, meaning:
+
+* Must pass deterministic conformance tests
+* Match zk circuit constraints and output schemas
+* Provide proving/verifying key hashes or attestations
+* Protocol changes go through **Git-based workflows** with DAO-ready extensions for transparency
+
+The goal: no gatekeeping, only **verifiable compliance**.
+
+
+## Actor Roles in the Ecosystem
+
+Frostgate defines **three distinct roles**:
+
+### 1. Provers
+
+Generate zk-proofs off-chain for message batches.  
+Incentivized for correct proof generation.
+
+### 2. Relayers
+
+Monitor source chains and transport proofs/messages to destination chains.  
+Act as trustless messengers in the Frostgate network.
+
+### 3. Verifiers
+
+Smart contracts on destination chains.  
+Validate zk-proofs and execute source chain payloads.
+
+All roles are **stateless** and **interchangeable**—anyone can spin up a role without permission or staking.
+
+Incentives (e.g., sender-paid fees) are designed to cover gas costs and actor rewards—while keeping the protocol **open by design**.
+
+
+## Final Thoughts
+
+Frostgate isn’t just another interoperability bridge. It’s a **reimagining** of cross-chain messaging where **verifiability**, **modularity**, and **decentralization** are **first principles**, not afterthoughts.
+
+By separating **consensus replication** from **interoperability** and replacing **trust** with **proof**, Frostgate offers a design that’s:
+
+* Lean  
+* Extensible  
+* Ready for a multi-chain future
+
+---
+
+No light clients.  
+No multisigs.  
+No committees.
+
+Just math, messages, and modularity.
