Security & Finality in Cryptocurrency Transactions - Dash offers deterministic finality for transactions, unlike cryptocurrencies relying on probabilistic security [1] - Deterministic security ensures a payment cannot be reversed, while probabilistic security only offers a high likelihood of non-reversal [1] - Dash achieves deterministic security through InstantSend, which instantly locks transactions, and ChainLocks, which locks the first-seen block [2] - Other cryptocurrencies like Litecoin, Dogecoin, and Bitcoin Cash rely on probabilistic security, making them less certain [3] - Even Bitcoin Cash implemented 10-block rolling checkpoints to improve deterministic finality [4] Dash vs Bitcoin - A Dash payment can be more secure than a Bitcoin transaction [1] - Dash payment finality can be achieved in under 2 seconds, faster than Bitcoin [5] - Bitcoin's security relies on a large hashrate, making reorgs unlikely but still possible [5] Industry Perspective - Deterministic finality is essential for secure cryptocurrency transactions [4][6] - Services should configure their nodes to check for InstantSend locks or ChainLocks to ensure payment security [3] - Blockchains offering instant deterministic finality are expected to outperform others [5]
