How Rome Scales Ethereum

Details the transaction flow through OP Geth, Rhea, Solana EVM, Hercules, and settlement on Ethereum.

Ethereum compose with Solana

• Integration and Transaction Initiation: Transactions begin on a Layer 2 Optimistic Ethereum rollup and are efficiently prepared for Solana's ecosystem by Rhea, showcasing the seamless integration with Solana for enhanced execution.

• Enhanced Execution with Solana EVM: Leveraging Solana EVM's ability to quickly process and sequence transactions, demonstrating how Solana's architecture supports diverse blockchain technologies.

Ethereum scale with Solana

• High Throughput Processing with Hercules: Hercules manages data updates and transaction processing, effectively scaling the system to handle higher volumes and reduce bottlenecks.

• Finalization and Commitment on Layer 1: The Proposer finalizes transactions by committing them to the main Layer 1 blockchain, ensuring all changes are securely recorded and durability is maintained.

Transactional Workflow Overview

OP Geth (L2 Based Rollup): Initiates transactions. Layer 2 rollups increase blockchain scalability by managing transactions off the main chain (Layer 1).

Rhea: Functions as a transaction processor, gathering transactions from OP Geth and sending them to the Solana EVM for execution.

Solana EVM: Receives and processes transactions from Rhea, providing Ethereum compatibility on Solana's high-performance blockchain.

Hercules: Manages data post-transaction processing in Solana, including updating account balances and processing state roots.

Interstate and Ethereum Smart Contract: Hercules submits transaction details to Interstate, which ensures the inclusion of transactions in Ethereum blocks. The Ethereum Smart Contract maintains account balances and transaction state roots, finalizing the state on the main Layer 1 blockchain.
