In the traditional financial circle, speed is important, but whether promises can truly be fulfilled is the key. Imagine you transfer hundreds of millions of dollars to a bank, and the bank tells you, "This money might be reclaimed in a few hours." Would you still trust it? This is the long-standing dilemma faced by blockchain.

Currently, mainstream public chains adopt a probabilistic settlement model. Leading projects like Bitcoin and Ethereum, even after transaction confirmation, theoretically still have the possibility of being "rolled back." For banks and exchanges, this uncertainty is a nightmare—it means they cannot accurately calculate settlement risks.

The DUSK project aims to break this situation by introducing the SBA (Byzantine Isolation Agreement) consensus mechanism. Its core feature is one word: once a transaction is on the chain, it is permanently irreversible. Not "possibly final," but "absolutely final."

What makes this mechanism so powerful? First, validators can participate in consensus anonymously. You don't need to disclose how much DUSK you hold, nor reveal your identity. Institutional privacy is protected, and large token holders don't have to worry about targeted attacks. Second, SBA has a very strong anti-fork capability. Through multiple rounds of random sampling verification, it fundamentally prevents chain splits.

In simple terms, DUSK is using technical language to answer a question: how to make blockchain as "reliable" as traditional finance?
