The Main Consensus Loop is the mechanism that allows the Dusk Network to reach fast, secure, and privacy-preserving transaction finality. Unlike traditional blockchains, which rely on visible leader elections or energy-heavy mining, Dusk uses cryptography to combine privacy, fairness, and regulatory compliance in a single process.
At the heart of Dusk’s consensus is the Succinct Attestation-based Byzantine Agreement (SBA). Each round, the loop coordinates how blocks are proposed, validated, and agreed upon—even if some participants act maliciously—ensuring deterministic network progress with strong security guarantees.
The process begins with private leader selection. Block proposers, called Generators, are chosen using the Proof-of-Blind-Bid system. Participants compute a hidden cryptographic score based on their secret bid, and only those exceeding a threshold can propose a block. This prevents front-running, censorship, and targeted attacks.
Once a block is proposed, it enters verification and reduction phases. Multiple participants independently check the block’s validity, including transactions and cryptographic proofs. The reduction phase narrows multiple proposals into a single candidate without revealing sensitive information.
In the agreement phase, honest participants vote to finalize the block. As long as the honest majority of staked DUSK exceeds Byzantine influence, the block achieves near-instant finality, making reversals practically impossible—a critical feature for financial and institutional applications.
Privacy is preserved throughout: transaction details, participant identities, and bidding data remain confidential, while zero-knowledge proofs ensure correctness. Selective disclosure allows compliance checks when required, balancing confidentiality with regulatory needs.
The loop also ties into DUSK token economics. Staking determines eligibility, and participants are rewarded or penalized to encourage honest behavior and prevent Sybil attacks.
Overall, Dusk’s main consensus loop replaces transparency-based trust with cryptographic guarantees, delivering secure, private, and institution-ready finality—paving the way for regulated DeFi and on-chain markets.
