Transactions are bundled into blocks. Each block records the hash of the previous block, linking them together into a chain.
“Decentralization” means that no single institution controls the ledger. The rules are written into the code, and many nodes verify them together.
Bitcoin was the first blockchain system to operate at scale. $BTC is the native coin of the Bitcoin network. Current price: 82497.99.
