Distributed Ledger

A list of transactions that exists on every computer that elects to run blockchain software.

Desktop Client

An application created to run on a user's PC.

Difficulty

A measure of how much hashing power (computing power) is required to find the next block on a blockchain. Difficulty increases over time on blockchains.

Decentralized Identity Foundation (DIF)

A group of businesses and organizations working together to build a globally-accepted identity verification system. The DIF uses blockchain technology to create a system that doesn't require a centralized authority for purposes of identification.

Digital Signature

A unique, encrypted output that cannot be duplicated. Useful for creating digital identities and confirming authenticity.

Distributed Autonomous Company

An organization that operates to earn profits for its shareholders (coin holders) by creating value for the free market.

Darksend

An aspect of the Darkcoin crpytocurrency that allows users to make anonymous transactions.

Days Destroyed

A metric for measuring bitcoin inactivity. Each day a Bitcoin remains unspent is another day added to its total number of Days Destroyed.

dPoW

Delayed Proof of Work, the consensus mechanism used by Komodo. dPoW allows one blockchain to take advantage of the security and hashing power of a second blockchain (Bitcoin, in Komodo's case). 

DDoS Attack

Distributed Denial of Service Attack. A means by which a malicious individual shuts down another individual's internet connection by overloading it with requests.

Darknet

A network that requires special software (like TOR) to access. Websites on the Darknet are much more difficult to shut down than normal websites. The Darknet was one of the first communities to use cryptocurrencies for transactions.

Dynamic Reserve Pool

A feature which allows KyberNetwork to maintain high levels of liquidity. The DRP keeps reserves of cryptocurrencies and establishes rates of exchange between them, allowing any user to easily trade one crypto for another.

DDoS

Distributed Denial of Service. A means by which a malicious individual shuts down another individual's internet connection by overloading it with requests.

dApps

Distributed Apps. Applications without centralized control.

DEX

Decentralized exchange. A platform (which isn't controlled by any single authority) that allows users to buy and sell cryptocurrencies.

Deepweb

Parts of the Internet that are not accessible through ordinary means, like search engines.

DAG

Directed Acyclic Graphs. Also referred to as “Tangle.” DAG is an alternative to the “chain of blocks” architecture used in many crypto projects.

Deflation

The limiting or decreasing of a cryptocurrency's supply, which usually drives its price up.

Dice

An over/under guessing game that uses random number generators to output results, allowing individuals to bet using cryptocurrencies.

Demurrage

A tax on cryptocurrency holdings that encourages spending coins because they are constantly being destroyed.

Distributed Network

Uses nodes spread out across many different locations to achieve decentralization.

Desktop Wallet

Software that allows its users the ability to store cryptocurrency on their personal computer.

Dump

The act of selling cryptocurrency.

DPoS

Delegated Proof of Stake. A consensus mechanism that has a blockchain's nodes vote on the correct version of the blockchain. 

Deterministic Wallet

Software for storing cryptocurrency that offers decreased risk of losing funds because of its ability to generate unlimited addresses from a single starting point, or "seed."

Double Spend

A famous problem that occurs when cryptocurrency is spent more than once. Miners and transaction finality ensure that double-spend cannot occur.

Dust Transactions

Transfers of value that are too small to be sent due to the proportionately high fee incurred. 

Dogecoin

A cryptocurrency that uses the “Doge” meme with a cult-like following.

Digital Asset

Any non-physical object of value, like a document, an audio file, or a logo, that can be owned and controlled.

DAO

Decentralized Autonomous Organization. An organization governed by smart contracts founded to allocate funds to cryptocurrency projects.

Digital Identity

A set of data used to represent an entity on a network or on the Internet.

Delegated Byzantine Fault Tolerance

A consensus mechanism that uses professional nodes to broadcast a version of the blockchain. If two thirds or more of the nodes agree, that block is written onto the chain. 

Decentralized

Distributed amongst its users rather than controlled by one group or within one certain area.

Delegated Proof of Stake

DPoS. A consensus mechanism that has a blockchain's nodes vote on the correct version of the blockchain. 

Digital Asset Array

DAA. A collection or portfolio of assorted cryptocurrencies. For example, one Digital Asset Array could contain BTC, ETH, and DASH.
