Blockchain
A linked-block history and network mechanism; it does not imply immediate finality for every transaction.
Concept and usage
A linked-block history and network mechanism; it does not imply immediate finality for every transaction.[1][2]
In context
A blockchain records batches of transactions or state and links them under network rules. Nodes verify and synchronize records according to a protocol. Consensus, block production, fees and finality differ between networks.[1][2]
Common confusion
Publicly inspectable records do not expose every account detail or imply that transactions are reversible or instantly irreversible. A centralized service can update its own database without producing an on-chain transaction each time.[1][2]
Example
An increased platform balance does not by itself prove an equal transfer on a public chain. Inspecting the network requires an address or transaction hash and an understanding of that network’s status model. A public chain record does not independently verify identity or service-side reconciliation.[1][2]
