# Rome 共享排序器

Rome rollup 由 rollup 的客户端（如 OP Geth）、作为共享排序器的 Rhea、部署在 Solana 上的 rollup 智能合约以及 Hercules 组成。

1. **Rhea** 接收 rollup 交易，将其打包为 Rome（Solana）交易，并提交到 Solana 以进行排序。
2. **Solana** 作为所有 rollup 的全局状态机，因为它们以智能合约形式驻留在 Solana 上。rollup 交易首先在 Solana 上执行，更新 Solana 上的 rollup 状态。Solana 决定交易的顺序。
3. **Hercules** 接收来自 Solana 的区块并在 rollup 上执行该区块的负载，从而推进 rollup 的状态。
4. **数据可用性** 通过将数据发布到 Solana、Celestia 或 Ethereum（基于 rollup 配置）来提供。
5. **结算** 通过将状态提交到 Ethereum 来完成。
