- Inbox Tracker: L1 event monitoring and processing (structure ready, implementation in progress)
- Consensus Engine: Arbitrum-specific consensus logic (interface defined, core logic development)
- Transaction Pool: L2-optimized transaction management (basic structure, validation pending)
- Storage Layer: High-performance state management (interface ready, optimization ongoing)
- Validator: Challenge mechanism implementation (framework established, proof system integration needed)
- Complete Reth SDK NodeBuilder integration
- Implement basic L1 connection and monitoring
- Basic transaction pool with L2 gas pricing
- Simple consensus engine for L2 block production
- Core storage layer with state management

- Cross-chain bridging enhancements
- Performance optimizations and benchmarking
- Comprehensive testing and security audits
- Mainnet deployment preparations
- Documentation and developer tools
- Community and ecosystem integration
- Performance benchmarks vs existing solutions
Arbitrum-Reth leverages the latest Reth SDK using the NodeBuilder pattern:
use reth_ethereum::EthereumNode;
use reth_node_builder::NodeBuilder;
// Build custom Arbitrum node with Reth SDK
let node_handle = NodeBuilder::new(config)
// Install Ethereum-specific node primitives
.with_types::<EthereumNode>()
.with_components(|ctx| {
// Customize components for Arbitrum L2
ctx.components_builder()
.network(|network_builder| {
// L1 connection management
// Arbitrum peer discovery
// L2 message propagation
network_builder.build()
})
.pool(|pool_builder| {
// L2 gas pricing
// Transaction validation
// Sequencer ordering
pool_builder.build()
})
.consensus(|consensus| {
// L1 finality integration
// Rollup state transitions
// Challenge mechanisms
consensus
})
.evm(|evm_builder| {
// Arbitrum precompiles
// Custom opcodes
// Gas metering
evm_builder.build()
})
.build()
})
