Recently, while pondering the clearing logic of traditional capital markets, I realized a fundamental principle: certainty.

Look at how Nasdaq or the Pan-European exchanges operate. Asset delivery must be absolute and irreversible — this is not optional, but a strict requirement. There is no room for ambiguity.

Contrast this with how mainstream public blockchains operate. Bitcoin, Ethereum, and similar networks rely on "probabilistic finality" — in other words, transactions are considered secure only after N blocks confirm, from a statistical perspective. Sounds reasonable? But the problem is, for scenarios where financial institutions need T+0 instant settlement, this uncertainty is like a ticking time bomb. Who dares to gamble on rollback risks?

**Why do some choose Dusk?**

In essence, Dusk’s consensus design is not about competing for the general computing market, but targeting a specific financial pain point.

Business teams want to use distributed ledgers for asset registration, but they are aware — fork risks mean double spending, and long confirmation times lead to unnecessary losses. Both are pitfalls.

If your business can accept transaction delays of a few minutes, or tolerate a rollback probability of one in ten thousand, then a general-purpose public chain might suffice. But if you want to directly replace existing securities settlement systems? Sorry, every second of delay, every bit of uncertainty, translates into real capital costs. At this point, you need something else.

**Key capability: Partitioned Byzantine Agreement**

Dusk adopts a Partitioned Byzantine Agreement (SBA) as its core. The design idea is to solve this problem — achieving absolute, non-reversible finality in a distributed environment, while maintaining the network’s decentralization. Simply put, it aims for the kind of certainty found in traditional finance.
