Bitcoin

The Bitcoin blockchain, the OG of crypto, is a decentralized, immutable ledger of BTC transactions. Secured by proof-of-work, it laid the foundation for all crypto. Now, with BTCFi innovations like THORChain, Bitcoin gains DeFi utility—enabling swaps, liquidity, and yield without wrapping, while staying true to its native form.

Bitcoin is the first and most well-known cryptocurrency, often called digital gold due to its limited supply of 21 million coins. It operates on a proof-of-work consensus where miners solve complex puzzles to validate transactions and secure the network. This decentralized system allows peer-to-peer transfers without intermediaries like banks.

Bitcoin's blockchain records all transactions in a public ledger, ensuring transparency and immutability. Its value comes from scarcity and growing adoption as a store of value. Over time, it has inspired thousands of other cryptocurrencies and blockchain innovations.
