Sei vs Tezos

Sei is a parallelised Cosmos‑SDK Layer‑1 optimized for order‑book exchanges, using Twin‑Turbo consensus to reach 300–400 ms finality. Its built‑in matching engine lets dApps compose on a shared liquidity layer, and fee markets are denominated in SEI with bulk‑order discounts. The ‘V2’ upgrade adds EVM compatibility via SeiDB and WASM contracts side‑by‑side.

Tezos is a self‑amending Proof‑of‑Stake Layer‑1 that supports on‑chain governance, letting token holders adopt protocol upgrades without hard forks. Its latest ‘Mumbai’ upgrade activated Smart Rollups, allowing scalable L2s written in Rust and Wasm to inherit Tezos security. Tezos processes ~1 million contract calls daily and is popular for compliant tokenisation of securities in Europe.
