Network Participants

Pheasant Network consists of three participants - user, relayer and disputer.

• User: a participant who wishes to transfer tokens from one network to another through the bridge (e.g. send ETH on Optimism to Arbitrum)

• Relayer: an actor who accommodates users' requests to transfer assets from an origin chain to a destination chain (e.g. send ETH on Arbitrum to a user and receive their ETH on Optimism)

• Disputer: a party who flags the system when noticing a suspicious action on the network and challenges the transaction's validity. Anyone can be a disputer including users. They need to object to the relayer within a dispute period of about 30 min when they catch a dubious transaction since Ethereum's BLOCKHASH opcode limitation only allows verification for transactions in the last 256 blocks at this time, and they might fail to spot invalid transactions. (e.g. question a relayer when a user has yet to receive their asset on a destination chain after a certain period, detect an invalid transactional data registered with BridgeChildContract)
