Chain
A chain is an ordered, consensus-accepted sequence of blocks or states representing a blockchain network's canonical transaction history. Nodes can temporarily observe…
Chain Halt
A chain halt is a period when a blockchain stops finalizing or producing valid new blocks, preventing normal transaction settlement. Causes include…
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 ID
A chain ID is a network-specific identifier used to distinguish blockchain environments and prevent transactions from being valid on unintended chains. The…
Chain Indexing
Chain indexing transforms raw blockchain blocks, transactions, logs, and state into searchable records optimized for application queries and monitoring. Indexed data is…
Chain Recovery
Chain recovery is the coordinated process of restoring valid blockchain progress after a halt, corruption, exploit, or severe consensus failure. Recovery can…
Chain Reorganization
A chain reorganization replaces one previously accepted block branch with another, potentially removing or reordering transactions near the chain head. Short reorganizations…
Chain Rollback
A chain rollback moves accepted ledger state back to an earlier block, discarding later state changes before operation continues. Transactions after the…
Chain Tip
The chain tip is the newest known block at the end of a blockchain branch, which may be canonical, competing, or unfinalized.…
Chain TVL
Chain TVL estimates the current value of assets deposited in tracked decentralized-finance contracts across a particular blockchain network. TVL is an analytical…
Chain-Specific Address
A chain-specific address is encoded or scoped for one blockchain's account, script, checksum, and network rules rather than universal use. Some ecosystems…
Chainlink (LINK)
Chainlink is a decentralized oracle platform connecting smart contracts with external data and services, while LINK supports payments and network security. LINK…
Chainlink Node
A Chainlink node is operator-run software that executes oracle jobs, communicates with external systems, and submits verified results to blockchains. Nodes vary…
Checkpoint Bridge
A checkpoint bridge transfers messages or assets using periodically finalized source-chain checkpoints that destination contracts accept as verification anchors. This design avoids…
Checkpoint Proof
A checkpoint proof cryptographically demonstrates that a block, state, transaction, or message belongs beneath an accepted checkpoint commitment. Proof validity has two…
Child Pays for Parent (CPFP)
Child Pays for Parent raises a Bitcoin transaction package's effective fee by spending an unconfirmed output with a high-fee child transaction. Miners…
CIP-25
CIP-25 is Cardano's media token metadata standard for associating native assets with descriptive fields stored in minting transaction metadata. The asset itself…
CIP-68
CIP-68 is Cardano's datum metadata standard for programmable native assets whose metadata can be read and updated through on-chain outputs. Unlike transaction-metadata…
Client Implementation
A client implementation is a specific software codebase that applies a blockchain protocol's networking, validation, execution, and consensus rules. Multiple independent implementations…
Cluster Node
A cluster node is a computer participating in a defined blockchain cluster by validating, relaying, executing, storing, or serving network data. Membership…
Committee-Based Consensus
Committee-based consensus relies on a selected subset of eligible participants to propose, vote, attest, or finalize decisions for the wider network. The…
Community Node
A community node is independently operated blockchain infrastructure offered by an ecosystem participant for validation, relaying, RPC access, or public support. The…
Compact Block Filter
A compact block filter is a small probabilistic summary enabling light wallets to identify blocks that may contain relevant scripts or transactions.…
