Filecoin vs Sei

Filecoin is a decentralized storage network where miners commit disk capacity and prove it through Proof‑of‑Replication and Proof‑of‑Spacetime. Clients pay FIL to store or retrieve data, and retrieval miners serve content over an IPFS‑compatible network. The 2024 ‘Hydra’ upgrade introduced delegated staking and boosted retrieval markets, while the Filecoin Virtual Machine (FVM) now lets developers deploy EVM‑style smart contracts that can automate deals or tokenize data.

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.
