Rosen Bridge is an open-source cross-chain asset transfer protocol built around Ergo as a central hub, enabling bridging between blockchains including Cardano, Bitcoin, and Ethereum. Its architecture uses two layers of participants: Watchers, who monitor origin chains and report bridge events on Ergo, and Guards, a federated multisignature group who process and execute transfers. Security is reinforced through collateral requirements in the native RSN token and ERG, cold storage mechanisms, and a Proof of Event incentive scheme that rewards honest participation and penalizes fraud. The protocol is designed to minimize smart contract exposure on bridged chains, supporting modular integration of new networks via independent chain-specific modules. RSN serves as the utility token underpinning collateral, staking, and reward distribution across the system.
