The Bitcoin network operates on a decentralized blockchain - a public ledger that records all transactions. This blockchain is maintained by thousands of nodes around the world, making it extremely resistant to censorship and fraud.
One of Bitcoin's most important features is its fixed supply cap of 21 million coins. This scarcity, combined with increasing adoption, has led many to view Bitcoin as digital gold - a store of value that could hedge against inflation and currency devaluation.
