Dash (formerly known as Darkcoin and XCoin) is an open source peer-to-peer cryptocurrency that aims to be the most user-friendly and most on-chain-scalable cryptocurrency in the world. On top of Bitcoin's feature set, it currently offers instant transactions (InstantSend), private transactions (PrivateSend) and operates a self-governing and self-funding model that enables the Dash network to pay individuals and businesses to perform work that adds value to the network. Dash's decentralized governance and budgeting system makes it a decentralized autonomous organization (DAO). - Wikipedia
The foundation of Dash is its blockchain, which is a decentralized ledger of all transactions that have ever taken place. This blockchain is secured through a consensus mechanism called “Proof of Work” (PoW). Through a process called “mining,” people use specialized computers to solve extremely difficult math problems. If their solution is correct, they receive the right to add a new block to the blockchain. Once the network verifies that the problem was correctly solved, a new block is added to the blockchain and the miner is rewarded with Dash currency.
Dash, like Bitcoin and most other cryptocurrencies, is based on a decentralized ledger of all transactions, known as a blockchain. This blockchain is secured through a consensus mechanism; in the case of both Dash and Bitcoin, the consensus mechanism is Proof of Work (PoW). Miners attempt to solve difficult problems with specialized computers, and when they solve the problem, they receive the right to add a new block to the blockchain. If all the other people running the software agree that the problem was solved correctly, the block is added to the blockchain and the miner is rewarded.
- Untraceable payments
- Unlinkable transactions
- Double-spending proof
- Blockchain analysis resistance
- Egalitarian proof of work
- Adaptive limits
- Difficulty retargets each block
- Block reward decreases each block according to the formula:
BaseReward = (MSupply - A)/218, where MSupply = (264 - 1) atomic units and 'A' is amount of already generated coins
- POW mechanism is a voting system for users
