Filecoin vs Stacks

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.

Stacks is a Bitcoin Layer‑2 secured by Proof‑of‑Transfer where miners commit BTC to mint STX and anchor blocks to Bitcoin every 10–15 minutes. Clarity smart contracts enable DeFi with Bitcoin finality, and the sBTC proposal aims to bring a two‑way peg for native BTC on chain. The Nakamoto upgrade scheduled for 2025 will reduce block times to five seconds and add probabilistic Bitcoin finality.
