After reviewing several high-performance public blockchain node attack incidents, I once again realize the foresight of @Dusk in consensus layer design. The biggest hidden danger of traditional PoS (Proof of Stake) does not actually lie in the 'rich get richer', but in the premature exposure of validator identities. Once an attacker knows who the next block-producing node is, DDoS attacks become inevitable. The most interesting aspect of Dusk's SBA (Separated Byzantine Agreement) is that it incorporates the 'lottery' process into zero-knowledge proofs. This 'Private Sortition' mechanism turns the election process of validating nodes into a black box. When I looked at the code logic, I found that nodes do not need to expose specific staking amounts or identities to prove their eligibility for consensus; they only need to submit a proof. This means that attackers have no idea who to attack before the block is finalized. For a chain aimed at supporting financial settlement, this ability to resist censorship and attacks is a baseline, not an elective course. Additionally, I am impressed by #Dusk's obsession with 'Immediate Finality'. The most feared thing during financial settlements is chain forks. If an asset transaction is rolled back a few minutes later due to the long-chain principle, it can be devastating to the credibility of the financial system. The SBA mechanism ensures that as long as a block is certified by the committee, it is irreversible. This design sacrifices probabilistic eventual consistency in pursuit of absolute settlement certainty. This is technically much more challenging than simply stacking high TPS because it requires extremely efficient network communication. If Dusk can truly maintain such high consensus efficiency on its mainnet, it offers traditional financial institutions not just a ledger but an execution environment with legally binding settlement certainty. This is what an 'institutional-level public blockchain' should look like. #dusk $DUSK
