Blockchain is a decentralized, immutable public ledger that records bitcoin transactions across a distributed network. It ensures transparency, security, and consensus without a central authority.
bitcoin differs from traditional money by being decentralized (no central authority), borderless (global, permissionless transfers), and finite (21 million cap), reshaping value transfer and monetary policy.
A global ban on bitcoin is nearly impossible: its decentralized, cross-border network, open-source code, distributed miners and users, and peer-to-peer transfers resist centralized enforcement and shutdown.
bitcoin achieves trust without intermediaries using a peer-to-peer network, proof-of-work mining, and consensus rules. Nodes validate transactions and blocks, ensuring immutability and preventing double-spending.
Blockchain is a decentralized, tamper-resistant public ledger that records bitcoin transactions in linked blocks. It ensures transparency, security, and consensus without a central authority.
