CORE vs Stacks

Core is an EVM Layer‑1 that merges delegated proof‑of‑stake voting with hash power from Bitcoin miners through the Satoshi Plus consensus. Validators bond CORE and lease BTC hash via a smart‑contract marketplace, aligning incentives between miners and token holders. The chain offers a native bridge to Bitcoin enabling one‑step transfers of cbBTC and supports Solidity smart contracts.

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.
