Block height is the numerical distance between a given block and Bitcoin’s very first block (the genesis block, height 0)

A block header is the compact 80-byte bundle of metadata that summarizes a Bitcoin block. By chaining and securing these headers together, miners protect the blockchain, and nodes can verify it efficiently.

A block is a structured data unit that batches validated Bitcoin transactions and links to the previous block via its hash, forming one step in the ever-growing blockchain ledger.

A blockchain is a publicly auditable ledger in which transactions are grouped into cryptographically linked blocks and agreed upon by a decentralized network of nodes running proof-of-work consensus.

A protocol that enables advanced smart contracts on Bitcoin through off-chain computation and on-chain verification, without requiring changes to Bitcoin's consensus rules.

A signature scheme that provides anonymity by allowing one party to sign a transaction without learning the details of the transaction.

Bitcoin's native programming language used to define how bitcoins are spent and who can spend them.

A type of zero-knowledge proof in Bitcoin-related systems that enable confidentiality without revealing transaction amounts.

The official open-source software client for the Bitcoin network.

A cryptographic protocol that enables signers to stay anonymous among
