Conflicting Transaction
A conflicting transaction is one that cannot validly coexist with another transaction because both claim the same spendable input, sender nonce, state…
Glossary terms starting with C
Numbers and symbols are grouped under #. Letter matching ignores case and uses the first displayed title character.
Congestion
Congestion occurs when demand for blockchain transaction processing exceeds the capacity available under current block, gas, or execution limits. Pending transactions compete…
Consensus
Consensus is the process by which distributed blockchain participants agree on one valid ordering and state despite faults, delays, or adversaries. Consensus…
Consensus Algorithm
A consensus algorithm is the concrete computational procedure nodes follow to select proposals, exchange votes, resolve conflicts, and decide ledger history. Algorithms…
Consensus Attack
Consensus Attack is an attack or weakness pattern that manipulates or disrupts the mechanism nodes use to agree on valid transaction ordering…
Consensus Bug
A consensus bug is a software defect that can make nodes disagree on valid blocks, state transitions, votes, or finality. If only…
Consensus Capability
Consensus capability is a node or component's supported ability to propose, validate, vote, finalize, or verify decisions under a protocol. Capabilities depend…
Consensus Client
A consensus client runs a blockchain's agreement layer, managing peers, validator duties, fork choice, attestations, and finalized consensus state. The consensus client…
Consensus Committee
A consensus committee is a designated group of validators assigned to attest, vote, aggregate, or decide protocol state during a defined interval.…
Consensus Engine
A consensus engine is the software component coordinating block proposal, voting, fork choice, and finalization around an application's state transitions. Frameworks may…
Consensus Epoch
A consensus epoch is a protocol-defined period that groups multiple slots, rounds, blocks, or validator duties for consensus accounting. Networks may use…
Consensus Failure
Consensus failure is a condition in which a blockchain cannot maintain its required safety, liveness, or agreement guarantees. It can appear as…
Consensus Finality
Consensus finality is the point at which protocol rules provide sufficient assurance that an accepted block will not be reversed. Finality can…
Consensus Fork
A consensus fork is a divergence in blockchain history or protocol interpretation caused by participants not agreeing on the same valid chain,…
Consensus ID
A consensus ID is an identifier that binds consensus messages, participants, rounds, networks, or instances to the correct agreement context. The exact…
Consensus Latency
Consensus latency is the time between proposing a transaction or block and reaching the protocol's required agreement or finality level. Latency changes…
Consensus Layer
The consensus layer coordinates validators and selects finalized blockchain history, while an execution layer applies transactions and computes application state. Ethereum after…
Consensus Mechanism
A consensus mechanism is the broader economic and governance design that determines who participates in agreement and how honest behavior is enforced.…
Consensus Message
A consensus message is a protocol message exchanged by blockchain nodes to propose blocks, vote, attest, commit, report state, or coordinate progress…
Consensus Node
A consensus node is a network participant that runs the consensus protocol or supports it by validating, relaying, and tracking blocks and…
Consensus Participant
A consensus participant is an eligible node or actor that proposes, validates, votes, attests, mines, or otherwise contributes to agreement. Eligibility may…
Consensus Payload
A consensus payload is the protocol data proposed, voted on, or committed during agreement, such as a block, header, or execution result.…
Consensus Protocol
A consensus protocol is the complete message, state-machine, timing, and decision specification that distributed participants follow to reach agreement. The protocol is…
Consensus Quorum
A consensus quorum is the minimum voting power or participant threshold required for a protocol decision, such as accepting a proposal, committing…
