In this talk, we will take a look at Sei's groundbreaking implementation of parallelized virtual machine (VM) execution and optimistic block processing - the industry's first of its kind on mainnet.

At the core of Sei's performance is its proprietary Twin-Turbo Consensus mechanism, which combines intelligent block propagation with optimistic block processing. This dual approach significantly reduces block times, achieving single-slot finality in under 400 milliseconds.

Sei's architecture uniquely merges the scalability of Solana's monolithic infrastructure with the rich tooling and developer communities of both the Ethereum Virtual Machine (EVM) and WebAssembly (WASM). This integration is done through pointer contracts and EVM precompiles, granting developers the flexibility to write decentralized applications (dApps) in either Solidity or Rust. Pointer contracts act as interpreters, enabling seamless interoperability between EVM and WASM environments. This ensures that tokens and contracts can operate across both VMs without the need for wrapping or duplication.
