Dusk's Succinct Attestation (SA) consensus algorithm is permissionless and committee-based Proof of Stake, optimized for high throughput and fast finality, which is necessary in financial applications. In contrast to traditional Proof of Work, SA eliminates energy-consuming mining, cutting down on environmental costs by more than 99% in comparison to systems like Bitcoin.
SACompletion rounds and iterations with the selection of provisoners (stakers) for proposing and validating blocks via Deterministic Sortition. Each round consists of proposal, validation, and ratification stages that ensure consensus in seconds. The proposal process further includes rolling finality, ensuring that iterations and computation are minimized and the chain is secured against forks.
Notably, SA also uses incentive schemes to discourage malicious activities and ensure high levels of active participation. Incentives are used to reward block generators and voters in addition to punishing mistakes like double-voting or inactivity. This ensures that the network is live, safe, and decentralized with minimal environmental impacts that would have resulted from PoW. For institutions, SA provides a sustainable, fast, and secure layer for reaching a consensus, meeting performance requirements in real-time trading and settlement.
