Polygon Edge is a modular and extensible framework developed by Polygon Technology. Its primary purpose is to bootstrap new Ethereum-compatible blockchain networks. Similar to Hyperledger Besu, a Polygon Edge network can either be permissioned or public. On SettleMint, all Polygon Edge networks are permissioned which means that only a set of specified nodes can join the network.
Polygon Edge's main features include:
- Permissioning: Only specified nodes can join and participate in the network.
- Ethereum compatible: A Polygon Edge network is fully compatible with Ethereum smart contracts and transactions.
- Support for industry standard wallets: Users are able to interact with industry standard wallets through JSON-RPC.
- Cross-chain communication: Transfer assets to and from any Ethereum-compatible network, i.e Ethereum or Polygon thanks to the native ChainBridge.
A consensus mechanism defines the rules for the nodes in a blockchain network to reach an agreement on the current state of the blockchain ledger.
Polygon Edge supports two versions of the Istanbul Byzantine Fault Tolerant IBFT consensus mechanism: Proof of Stake (PoS) or Proof of Authority (PoA). Any Polygon Edge network deployed with SettleMint uses Proof of Authority.
