Bitcoin vs Linea

Bitcoin is the first decentralized blockchain, secured by proof‑of‑work where miners expend SHA‑256 hash power to find valid blocks every ~10 minutes. The supply is capped at 21 million coins, with inflation halving roughly every four years—the most recent halving occurred on 20 April 2024. Upgrades like SegWit and Taproot have enabled second‑layer protocols such as the Lightning Network and emerging covenants via OP_CTV debates.

Linea is Consensys’ zkEVM rollup offering bytecode‑level equivalence with Ethereum and zero‑knowledge proofs generated by the Scroll‑inspired ‘Plonky3’ prover. The network is integrated directly into MetaMask, and sequencer fees can be paid in any ERC‑20 via a paymaster contract. Linea has secured over 200 million TVL and finalises proofs on mainnet every 10 minutes.
