Capitalizations Index – B ∞/21M
Blockchain is a public, decentralized ledger that records bitcoin transactions across a distributed network. Immutable blocks link via cryptographic hashes, ensuring transparency, security, and trust without intermediaries.
A bitcoin hash is a fixed-length cryptographic output derived from transaction data and block headers; miners compute hashes to secure the network, verify blocks, and meet proof-of-work difficulty targets.
Proof of Work requires miners to solve difficult cryptographic puzzles to add blocks and confirm transactions. bitcoin uses PoW so altering history becomes computationally impractical.
bitcoin cannot be counterfeited because transactions use cryptographic signatures, decentralized consensus, and proof-of-work to verify ownership and prevent double-spending, ensuring authenticity and integrity.
bitcoin operates as a decentralized peer-to-peer network where nodes validate transactions and relay blocks; cryptographic consensus via proof-of-work secures the ledger, preventing double-spending without central authority.
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’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 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.
