Bitcoin’s stack-based programming language for defining the conditions needed to spend transaction outputs.
A shared treasury output uses Bitcoin Script to require signatures from two designated keys before the BTC can move.
A specialized Ethereum data payload with a separate fee market and temporary availability rules, used by systems such as rollups.
The rollup puts compressed batch data in an Ethereum blob transaction instead of placing the full batch in ordinary calldata.
A batch of blockchain data that is accepted as one step in the network’s history.
An explorer shows several transactions inside one block. A node rejects that whole proposed block if it breaks a consensus rule.
An interface that indexes blockchain data for inspecting blocks, accounts and transactions.
"Did that swap actually go through?" You paste its transaction ID into an explorer to inspect the execution result and logs.
A compact set of block fields used to identify the block and check important validity requirements.
A miner changes the transactions in its candidate block. The Merkle root changes, so it must work with a different header hash.
A block’s numbered position in a chain, counted from the first block.
'My node is a few hundred blocks behind.' Comparing its block height with the network's current height shows the gap.
The Bitcoin block subsidy plus transaction fees that a miner may claim for a valid block.
A miner's coinbase transaction claims the allowed subsidy and the fees from the payments included in that block.
The interval between successive blocks, or a protocol's intended interval when quoted as a network statistic.
Bitcoin’s consensus measure of block capacity, introduced by SegWit.
Your wallet quotes 8 sats per virtual byte. Its estimate uses the transaction's weight-based size, not simply the raw file's byte count.
The interest rate charged on borrowed assets.
You check a loan after a busy week and find both a higher variable borrow rate and a larger outstanding debt balance.
