Born from a whitepaper. Built on cryptography. Reshaping money as we know it.
Bitcoin is the world's first decentralized digital currency. Created in 2009 by the pseudonymous Satoshi Nakamoto, it operates without any central authority — no banks, no governments, no intermediaries.
Transactions are verified by a network of computers (nodes) through cryptographic proof, recorded on an immutable public ledger called the blockchain. Every 10 minutes on average, a new block of transactions is added.
With a hard cap of 21 million coins, Bitcoin introduced programmatic scarcity to the digital world — making it the first asset in history where supply is mathematically guaranteed to be finite.

Every ~210,000 blocks (~4 years), the block reward is cut in half. This deflationary mechanism ensures Bitcoin's scarcity over time.
