A record system in which a record of transactions made in a cryptocurrency is maintained across multiple computers linked in a peer-to-peer network.

Centralized cryptocurrencies

Currencies that are centralized by design, compared to decentralized peer-to-peer currencies like Bitcoin, that are not governed by any central authority but by various consensus mechanisms and governance protocols. A centralized virtual currency is issued by a central system that establishes rules for its use, records transactions made by its users and reserves the right to withdraw the currency from circulation and take other necessary actions.

Closed-Loop Systems

Closed-loop systems are private or permitted off-chain or private Blockchain systems, e.g. DiamondBack Express


DiamondBackEU OU, “DiamondBack Group”


A cryptocurrency is a digital or virtual asset designed to work as a medium of exchange that uses cryptography to ensure its integrity and security. Cryptocurrency can be used as payment systems, money storage systems and, increasingly, as units of account. Cryptocurrency can often be programmable, meaning they can be created to include additional data besides nominal value. Cryptocurrency can be centralized or decentralized based on the Blockchains (or more generally the distributed ledger technology (defined below)) they run on.

DBK Coin/Token

Also referred to as the DiamondBack Coin, DBK Coin, or DBK Token, a Stableprice payment coin fulfilled by DiamondBackEU OU. A single DBK Coin/Token is priced at 1 USD.

DiamondBack Express/Express Club

DiamondBack Express is a closed-loop payment and rewards platform that supports its private membership club consisting of consumers, merchants, vendors and companies that use the DBK Token for payments of good and services between club members, P2P, C2B and B2B.

Distributed Ledger Technology (DLT)

A digital system for recording transaction of assets in which the transactions and their details are recorded in multiple places at the same time. Unlike traditional databases, distributed ledgers have no central data store or administration functionality.

Fiat Currencies

Fiat money is currency that a government has declared to be legal tender but in nearly all cases is not backed by a physical commodity: This includes the U.S. Dollar. The value of fiat money is derived from the relationship between supply and demand, controlled most directly by a central banking authority. In other words, the value of the money is dictated by a third party rather than determined by the value of the material from which the money is made.


The property of a good or a commodity whose individual units are essentially interchangeable. Since one kilogram of pure gold is equivalent to any other kilogram of pure gold, whether in the form of coins, ingots, or in other states, gold is fungible. The same is true for U.S. government issued money – any $20 bill can be replaced with any other $20 bill.


A Blockchain is designed to be immutable (unchangeable, irreversible). Once a piece of information is recorded onto a Blockchain it never changes. Blockchain data is considered legitimate because it has been validated by all the participants on a given network.


The term investment-grade does not constitute any relationship to an investment but references only to a class of top-quality stones traditionally accepted as most valuable.

Medium of Exchange

A medium of exchange is an intermediary instrument used to facilitate the sale, purchase or trade of goods between parties. It is one of the core functions of a cryptocurrency. For an instrument to function as a medium of exchange, it must represent a standard of value accepted by all parties. Stablecoins are considered to be the prime medium of exchange among cryptocurrencies.


Cryptocurrency on-ramps and off-ramps are mechanisms, including exchanges and markets, that make it possible for cryptocurrency holders and future holders to exchange fiat for cryptocurrency and then cryptocurrencies back into fiat.

Proof-of-Stake (PoS)

Proof-of-Stake (PoS) is a type of economic system expressed as an algorithm by which a cryptocurrency Blockchain network aims to achieve distributed consensus. In PoS-based cryptocurrencies the creator of the next block is chosen via various combinations of random selection and wealth or age (aka the stake).

Proof-of-Work (PoW)

Proof of Work describes an economic system expressed in the form of an algorithm that requires a not- insignificant but feasible amount of effort to deter frivolous or malicious uses of computing power, such as sending spam emails, launching denial of service attacks or registering the possession of digital assets.

Smart Contracts

A smart contract is a computer protocol intended to digitally facilitate, verify or enforce the negotiation or performance of a contract. Smart contracts allow the performance of credible transactions without third parties. In the case of the Company, they will be utilized to make new DBK Coins and to redeem those coins. Smart Contract transactions are trackable and immutable.

Sound Money

Money not liable to sudden appreciation or depreciation in value: stable money, specifically, a currency backed by or pegged to some good or commodity.


Stablecoin refers to a new class of cryptocurrencies which offer price stability. There are four main categories of Stablecoins: Blockchain-based Stablecoins, fiat-collateralized Stablecoins, crypto- collateralized Stablecoins and asset-collateralized Stablecoins.

Stableprice (As defined by DiamondBack)

Stableprice refers to the innovation that DiamondBack has created so that DBK can be a token that functions as a currency in the real world, as well as maintaining the utility of a Stablecoin. DBK is differentiated from a Stablecoin because DBKs are not synthetic dollars. Therefore, DBKs have regulatory advantages over Tether, USDC and other fiat backed Stablecoins, giving DBK a truly unique position in the marketplace.


The storing of value is the function of an asset that can be saved, retrieved and exchanged at a later time. The asset should be predictably useful when retrieved. A store-of-value is anything that retains purchasing power in the future.

Unit of Account

Unit of account is one of the functions of money. The value of something is measured in a specific currency. This allows different things to be compared against each other: goods, services, assets, liabilities, labor, income, or expenses. A unit of account lends meaning to profits, losses, liabilities, or assets.

Utility Token

Utility tokens are a type of virtual currency that have utility in a given Blockchain ecosystem. For example, one can have a utility token that are used for payments or represents a given number of customer loyalty points on a Blockchain that is used to manage that information for a retail chain. A utility token can also entitle a token holder to view streaming content on a video-sharing Blockchain. Utility tokens are tradable and transferrable among the various participants of the Blockchain (fungible).
