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.
