What Backs Bitcoin’s Value: Scarcity, Security, Network
bitcoin’s value rests on capped supply (21M), robust cryptographic security and proof-of-work, and a growing network effect-users, exchanges and infrastructure that enable liquidity and trust.
Bitcoin confirmations: Why six are considered secure
Six bitcoin confirmations are widely considered secure because each new block exponentially lowers the chance of a competing chain overtaking a transaction, making double-spend attacks practically infeasible for most attackers.
How Bitcoin Works: Peer-to-Peer Consensus and Validation
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.
What Is Blockchain? The Public Ledger Behind Bitcoin
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.
