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]

FoundationBlockchain basics: public records and private ledgersA blockchain links records under the rules of its network. Confirmation and consensus mechanisms differ, so one chain does not describe all networks. A public history provides a way to inspect transactions without establishing that all account information is stored on-chain.Related contextCrypto payment basics: asset, network and addressA token can exist on multiple networks. Confirm the accepted network, address format and any required tag. Selecting the right asset name but the wrong network can prevent a payment from being credited.Deeper analysisCrypto infrastructure: one asset, several networksAssets present on several networks require more precise payment classifications. An asset name does not identify the address format, fee asset or confirmation policy. A familiar ticker still needs a network context.
