D

  • Decentralized

    In the context of computer programs, decentralized refers to the notion that it includes a component that is run on many different computers and by many independent operators for the purpose of servicing a user

  • Decentralized Application (dApp)

    Application on a distributed network run by multiple independent operators. Typically refers to applications that operate on or make use of a blockchain

  • Delegate

    Block validator for the ICON network. Transaction processors for operations that change the state of the ICON network. Typically representing an end-user group that has made important contributions to the ICON network. Typically encouraged to incentivize the at-large ICON Community for participation and to help increase the value of the ICON network

  • Delegate Term

    The period of time that a delegate is voted to their position

  • Delegated Proof of Contribution [deprecated]

    A decentralized blockchain validation protocol whereby a group of delegates validate blocks on behalf of all nodes in the network. Validators stake a significant amount of currency to prove that their validations are legitimate at the risk of losing the staked currency

  • Delegated Proof of Stake

    A decentralized blockchain validation protocol whereby a group of delegates validate blocks on behalf of all nodes in the network. Validators stake a significant amount of currency to prove that their validations are legitimate at the risk of losing the staked currency

  • Delegation

    Contribution of voting power towards a delegate / validator candidate

  • Destination Blockchain

    Ending location of a transaction on the blockchain

E

  • End-user

    Person. A type of user that is either a person or a group of people

G

  • Governance

    A system for making and enforcing decisions

  • Governance Variable

    Network parameters including voter reward rate, public representative reward rate, contribution proposal system reward rate, and monthly inflation

  • Grant

    A monetary gift, where the recipient is typically expected to pursue some pre-defined goal with the money received

I

  • Light Node

    Maintains destination blockchain state on source blockchain. Passes state headers to relay

M

  • Machine-user

    Service that connects to another application. A type of user that acts on behalf of an end-user

  • Merkle Tree

    Computational structure for ensuring that computational events happen in a specific, logical order

  • Merkle Tree Accumulator

    Queue of concatenated merkle tree roots with cached hashes that can verify the inclusion of a given hash

  • Message Broker
