Dash (DASH) is an open-source blockchain and cryptocurrency focused on offering a fast, cheap global payments network that is decentralized in nature. According to the project’s white paper, Dash seeks to improve upon Bitcoin (BTC) by providing stronger privacy and faster transactions.
“Dash” is a portmanteau of “Digital Cash.”
A Brief History
Launched in January 2014 as “XCoin” by Evan Duffield, the project was quickly rebranded to “Darkcoin” to highlight its privacy features. In March 2015, it was rebranded again to Dash to shift its image from dark web associations to a mainstream payment solution. Since its inception, Dash has grown to include features such as a two-tier network with incentivized nodes, including “Masternodes,” and decentralized project governance.
How Does Dash Work?
Dash is built on the Bitcoin core code with significant modifications. It utilizes a Proof-of-Work (PoW) consensus mechanism with the X11 algorithm, which was designed to be ASIC-resistant (though ASICs for X11 now exist).
What truly sets Dash apart is its Two-Tier Network:
- Miners (Tier 1): Similar to Bitcoin, miners secure the network and create new blocks using the X11 algorithm.
- Masternodes (Tier 2): These are special servers that perform critical functions for the network. To run a Masternode, a user must prove ownership of 1,000 DASH. This collateral requirement prevents “Sybil attacks” (where one actor creates many fake identities).
Key Features
The Masternode network enables Dash’s most distinct features:
1. InstantSend
Bitcoin transactions can take minutes or even an hour to confirm. Dash’s InstantSend allows for near-instant transactions (less than 2 seconds). Masternodes form a quorum to lock the transaction inputs, preventing double-spending and rendering the transaction irreversible almost immediately.
2. PrivateSend (CoinJoin)
Now often referred to as CoinJoin within the Dash ecosystem, this feature offers financial privacy by mixing coins. It breaks down your transaction amounts into standard denominations (like 0.1, 1, 10 DASH) and mixes them with the funds of other users, making it extremely difficult to trace the origin of the funds.
3. ChainLocks
This security feature protects the blockchain against 51% mining attacks. Masternodes sign blocks as they are mined; once a block is signed (locked), it cannot be reorganized. This makes the Dash network highly secure.
Decentralized Governance (DAO)
Dash was one of the first cryptocurrencies to implement a Decentralized Autonomous Organization (DAO).
- Block Rewards: Unlike Bitcoin, where 100% of the block reward goes to miners, Dash splits the reward:
- 45% goes to Miners.
- 45% goes to Masternodes.
- 10% goes to the Treasury.
- The Treasury: This 10% creates a budget for development, marketing, and legal expenses. Anyone can submit a proposal to the network, and Masternodes vote on whether to fund it. This allows Dash to be self-funding and independent of third-party influence.
Conclusion
Dash remains a significant player in the cryptocurrency space by focusing on usability. Its goal is to make cryptocurrency as easy to use as cash or credit cards but with the benefits of decentralization. With its unique governance model and focus on speed and privacy, Dash continues to evolve as a robust payment network.
