Glossary Terms Starting with B

Block Header

A block header is the compact metadata portion of a block that commits to its parent, transaction or state data, timing, and…

Block Height

Block height is the number of blocks between a block and the genesis block, with the genesis block normally assigned height zero.…

Block ID

A block ID is the protocol-specific identifier used to reference a particular blockchain block, commonly a hash of its header or another…

Block Inclusion

Block inclusion is the event in which a valid transaction or operation is selected and recorded in an accepted block. Inclusion shows…

Block Interval

Block interval is the elapsed time between consecutive blocks, usually discussed as an observed value or protocol target rather than a fixed…

Block Limit

A block limit is a protocol rule that caps how much data, computation, gas, weight, or other resource one block may contain.…

Block Monitoring

Block monitoring continuously follows new blocks, reorganizations, execution results, and finality changes to maintain an accurate view of blockchain activity. RPC subscriptions…

Block Number

A block number is a sequential position assigned to a block within a blockchain history, often starting at zero for the genesis…

Block Producer

A block producer is the miner, validator, sequencer, or other protocol-authorized participant that proposes or creates a candidate block. The producer proposes…

Block Producer Selection

Block producer selection is the consensus process that determines which eligible participant may create or propose the next blockchain block. Selection rules…

Block Production

Block production is the recurring creation, validation, and publication of candidate blocks by miners, validators, or authorized blockchain participants. Peers independently validate…

Block Propagation

Block propagation is the peer-to-peer distribution of newly produced blocks or compact announcements across a blockchain network for validation. Large blocks, slow…

Block Proposal

A block proposal is a candidate block submitted by an eligible participant for network validation, voting, and possible inclusion in canonical history.…

Block Proposer

A block proposer is the miner, validator, authority, or selected participant responsible for submitting a candidate block during a production opportunity. Proposers…

Block Receipt Root

A block receipt root is a cryptographic root that commits to the ordered set of transaction receipts produced by executing a block.…

Block Relay

Block relay is the networking process and protocol used by peers or specialized services to transmit new blocks efficiently between participants. Specialized…

Block Reward

A block reward is the total protocol-permitted compensation associated with producing a block, commonly including newly issued assets, transaction fees, or both.…

Block Root

Block root is a general term for a cryptographic root or hash that represents a block, part of a block, or a…

Block Size

Block size is the serialized amount of data in a block, usually measured in bytes, although some protocols use weighted or multi-resource…

Block Space

Block space is the limited capacity within blocks for transaction data and computation, treated as a scarce network resource allocated through protocol…

Block State Root

A block state root is the cryptographic commitment to the blockchain state after, or at a protocol-defined point around, processing a block.…

Block Status

Block status describes where a block stands in the consensus lifecycle, such as proposed, canonical, confirmed, finalized, orphaned, or invalid. Status can…

Block Storage

Block storage is the node subsystem that persists blockchain headers, bodies, indexes, receipts, and related data for validation and retrieval. Full, pruned,…

Block Subsidy

A block subsidy is the newly issued cryptocurrency that a protocol permits a block producer to claim for creating a valid block,…
