Dash, derived from "Digital Cash," is an open-source blockchain and cryptocurrency that strives to provide a fast, cost-effective global payments network that is decentralized. Launched in January 2014 as a fork of Litecoin, Dash has evolved to include features such as a two-tier network with incentivized nodes, including "masternodes," and decentralized project governance. It also offers InstantSend for instantly settled payments, ChainLocks for instant blockchain immutability, and PrivateSend for optional transaction privacy. Dash was conceived by software developers Evan Duffield and Kyle Hagan, initially under the name XCoin, and later rebranded to Dash in March 2015.

Dash operates on a two-tier network. The first tier consists of nodes that perform mining operations under a proof-of-work consensus protocol. The second tier is made up of masternodes that provide advanced services and governance over Dash's proposal system. These masternodes, backed by collateral held in Dash, facilitate functions such as InstantSend, PrivateSend, and ChainLocks. Dash's unique proof-of-service consensus algorithm rates masternodes based on their history of providing good services to the network. This two-tier structure allows Dash to offer improvements in transaction speed, privacy, and governance.

Dash aims to be a user-friendly and scalable payments-focused cryptocurrency. It is designed for both individual users and institutions, including merchants, financial services, traders, and those who need to send international remittances. Dash's governance system distributes 10% of the block rewards for the development of the project in a competitive and decentralized way, allowing for the creation of many funded organizations. This makes Dash a potential choice for organizations looking to leverage blockchain technology for their operations.

Dash was launched in January 2014 by software developers Evan Duffield and Kyle Hagan. Initially named XCoin, it was rebranded to Darkcoin two weeks later and finally to Dash in March 2015. Before Dash, Duffield had experience in finance and public relations, having developed machine learning algorithms and search engines. He conceived Dash in 2012 with the intention of adding more anonymity to Bitcoin, hence the original name Darkcoin. Duffield served as CEO of Dash Core Group until December 2017 when he stepped down to focus on other strategic initiatives. Hagan co-authored the original Darkcoin whitepaper with Duffield but left the project in December 2014.

Dash operates on a unique two-tier network architecture that includes standard nodes and masternodes. The first tier, standard nodes, process and verify transactions in a manner similar to other digital assets, using a consensus mechanism known as Proof of Work (POW). Miners solve complex mathematical problems to validate transactions and add them to the blockchain. The second tier is made up of masternodes, special servers that perform specific functions and relay transactions. These functions include striving to provide increased privacy, instant transactions, and governance. Masternodes are required to hold a certain amount of Dash as collateral and receive non-financial incentives for their role. This two-tier network structure aims to provide efficient transaction times, manageable fees, and advanced features such as governance and budgeting.

Dash InstantSend is a feature that enables users to complete transactions in a matter of seconds. This is facilitated by a group of masternodes, which are servers that validate and secure transactions on the Dash network. When a user initiates a transaction, it is marked and sent to the network. A subset of masternodes is then randomly selected to form a consensus group. This group verifies the validity of the transaction, checks if it meets the necessary criteria, and if deemed valid, the masternodes lock the inputs of the transaction. Once locked, the input information is propagated through the network, signaling that the transaction has been secured. This entire process happens almost instantly, within a few seconds at most. Dash InstantSend is designed for speed and convenience, user experience, and security considerations. Dash InstantSend also aims to facilitate instant transactions, which could be a consideration for users.

Dash's PrivateSend feature is an aspect of the cryptocurrency that is designed with the intention to enhance user privacy by obscuring the origins of transactions. This feature is designed to maintain the fungibility of Dash coins by removing their history on the network. PrivateSend works by breaking down a user's transaction input into standard denominations, then mixing these denominations with the inputs of two other users, facilitated by a Dash masternode. This mixing process is repeated multiple times to ensure the origins of funds are fully anonymized. The result is a transaction that is difficult to trace back to the original sender, intending to provide privacy for Dash users. This feature is designed for users who prioritize transaction confidentiality.

Dash utilizes a governance model known as a Decentralized Autonomous Organization (DAO). This model is characterized by a network of masternodes that make decisions for the project. Each masternode has the ability to vote (yes/no/abstain) on each proposal. If a proposal passes, it can then be implemented by Dash’s developers. The DAO model allows for proposals to be submitted to the network, which are then voted on by the masternodes. As part of its DAO model, Dash uses 20% of the block subsidy to fund its own development. This self-funding mechanism is a feature of Dash's DAO model. This is one of the ways Dash operates within the cryptocurrency space.

Dash approaches scalability and transaction throughput on its blockchain by utilizing a two-tier network design. This design allows for the addition of extra services such as the decentralized mixing function, known as PrivateSend, and the instant transaction settlements known as InstantSend. Dash's network design alternative has resulted in an added layer of privacy protection, improved network throughput, expedited settlements, and efficient message propagation across the network. Dash's governance system contributes to its high level of decentralization. Dash features larger block sizes than Bitcoin, with 2 MB blocks, a 2.6-minute block generation time, and a settlement capability of approximately 56 transactions per second. Dash seeks to adapt to the payments industry, which often requires swift network confirmations at Point of Sale terminals.

DASH, the native cryptocurrency of the Dash ecosystem, plays a crucial role in facilitating transactions and maintaining the network's functionality. It is designed to be a digital currency that can be used for daily transactions, akin to other digital payment methods. Dash is run by a subset of its users, known as "masternodes", who have a starting stake of 1,000 DASH in their systems. These masternodes simplify the verification and validation of transactions, contributing to the efficiency of the Dash system. DASH is used to finance development projects within the Dash ecosystem, with a portion of block rewards being allocated to the treasury for this purpose. The masternodes, who are integral to the Dash ecosystem, play a crucial role in determining the development directions for the cryptocurrency.

Masternodes are servers that maintain a complete copy of the Dash blockchain and perform tasks related to block validation, InstantSend, and CoinJoin. They are acknowledged through a concept known as Proof of Service, alongside the Proof of Work done by miners. Masternodes are also given the opportunity to vote on governance and funding proposals, with each masternode receiving one vote on each proposal submitted to the system. To operate a masternode, proof of ownership of DASH collateral is required. The coins don’t need to be in the masternode, but they need to be kept in a certain way that is transparent to the entire network. If the owner moves or spends those coins, the masternode ceases to function and recognition ceases. Masternodes are recognized by the network for the InstantSend, CoinJoin, and governance services they provide. 20% of the block subsidy is allocated to the budget with the remaining 80% acknowledged between miners and masternodes. Masternodes are selected for acknowledgement in each block and moved to the back of the list after being acknowledged. If the collateral behind a masternode is spent, or if a masternode ceases providing services to the network for more than one hour, it is removed from the list until normal service resumes.

Dash strives to foster merchant adoption and integration for everyday transactions through its innovative payment app, DashDirect. This app is designed to facilitate day-to-day commerce transactions with a vast network of vendors and online retailers. DashDirect is a non-custodial app, meaning it connects with users' official Dash wallets, allowing them to retain control and ownership of their digital holdings. The app includes discounts as a primary feature, with the intention of adapting the discount scheme in response to userbase changes. DashDirect's unique merchant network and Dash's efficient, low-cost transactions contribute to an average reduction in transaction costs for users. This approach seeks to facilitate the use of digital currencies for everyday purchases, similar to traditional currencies, but with the added protections of decentralized digital currencies.

Dash's long-term vision is to ensure that every user has the ability to manage their own digital assets, offering freedom from centralized entities. The roadmap for Dash includes several upcoming features and modifications. These include modifications to the user experience, such as the introduction of DashPay Wallet, which intends to work towards simplifying transactions by allowing users to create usernames within the Dash network. Dash seeks to explore enhancements to its platform's scalability and security, with a focus on developing a decentralized API and making modifications to the InstantSend feature. Please note that while Dash seeks to achieve these goals, cryptocurrency development can be complex and unpredictable, and plans may change over time.
