Chain Halt

A chain halt is a period when a blockchain stops finalizing or producing valid new blocks, preventing normal transaction settlement.

Chain Head

The chain head is the latest block a node currently considers canonical under its fork-choice rule, though it may not be finalized.…

Chain Hopping

Chain Hopping is the movement of virtual assets across different blockchains, often through bridges, swaps, exchanges, or intermediary assets. It is used…

Chain ID

A chain ID is a network-specific identifier used to distinguish blockchain environments and prevent transactions from being valid on unintended chains.

Chain Indexing

Chain indexing transforms raw blockchain blocks, transactions, logs, and state into searchable records optimized for application queries and monitoring. An indexer may…

Chain Recovery

Chain recovery is the coordinated process of restoring valid blockchain progress after a halt, corruption, exploit, or severe consensus failure.

Chain Reorganization

A chain reorganization, or reorg, occurs when a blockchain node adopts a different valid chain history and some previously accepted blocks are…
