Dash: A Payments-Focused Cryptocurrency V2
A cryptocurrency based on Bitcoin, the work of Satoshi Nakamoto, with various improvements such as a two-tier incentivized network, known as the masternode network. Included are other improvements such as PrivateSend, for increasing fungibility, and lnstantSend, which allows instant transaction confirmation without a centralized authority.
Dash: A Privacy-Centric Crypto-Currency V1
A crypto-currency based on Bitcoin, the work of Satoshi Nakamoto, with various improvements such as a two-tier incentivized network, known as the Masternode network. Included are other improvements such as Darksend, for increasing fungibility and InstantX which allows instant transaction confirmation without a centralized authority.
Transaction Locking and Masternode Consensus: A Mechanism for Mitigating Double Spending Attacks
Bitcoin and other cryptographic currencies use a distributed system called the blockchain to gain consensus across the network. To protect against double spending attacks, vendors and other merchants usually wait for confirmation from a block that the transaction being sent was valid. A double spend is where an attacker sends two competing transactions, one of them promised to a merchant (or any other party), the other back to himself.
Darkcoin: Peer-to-Peer Crypto-Currency with Anonymous Blockchain Transactions and an Improved Proof-of-Work System
Darkcoin is the first privacy centric cryptographic currency based on Satoshi Nakamoto’s Bitcoin. DarkSend, a technology for sending anonymous block transactions is incorporated directly into the client using extensions to the core protocol. An improved proof-of-work using a chain of hashing algorithms replaces the SHA256 algorithm and will result in a slower encroachment of more advanced mining technologies (such as ASIC devices). DarkGravityWave is implemented to provide quick response to large mining power fluctuations.
