Architecture Overview
The diagram below illustrates the major coomponents of Edge.
Components
The following table breaks down each of these components.
| Component | Description | Link |
|---|---|---|
| libp2p | Provides the networking layer for Edge and is designed for peer-to-peer network architectures. | libp2p Overview |
| Bridge | An in-built bridging mechanism enabled by PolyBFT that allows message passing between an Edge-powered chain and another Proof-of-Stake blockchain without mapping. | Native Bridge overview |
| Mempool | Enables multiple validators to aggregate their signatures to create a single, aggregated signature representing all validators in the pool. | mempool Overview |
| Consensus | PolyBFT serves as the consensus mechanism of Polygon Edge and consists of a consensus engine, IBFT 2.0, and a consensus protocol that includes the bridge, staking, and other utilities. | PolyBFT Overview |
| Blockchain | Coordinates everything in the system, curates state transitions, and is responsible for state changes when a new block is added to the chain. | Blockchain Overview |
| Runtime (EVM) | Uses the EVM as the runtime environment for executing smart contracts. | Runtime Overview |
| TxPool | Represents the transaction pool, closely linked with other modules in the system. | TxPool Overview |
| JSON-RPC | Facilitates interaction between dApp developers and the blockchain, allowing developers to issue JSON-RPC requests to an Edge node and receive responses. | JSON-RPC Overview |
| gRPC | Essential for operator interactions, allowing node operators to interact with the client easily and providing a seamless user experience. | gRPC Overview |
