I, #MavisEvan started a long discussion on this topic because Dusk Network is not just another blockchain trying to look different. It actually works differently at the core. When most people talk about Layer 1 chains, they usually repeat the same ideas: Proof of Work, Proof of Stake, validators, staking rewards. Dusk does not reject these ideas blindly, but it rewires them in a smarter and quieter way.

At the heart of Dusk Network lies its own consensus design called Segregated Byzantine Agreement, or SBA. This system is built to solve three problems together: final settlement, decentralization, and privacy. Most blockchains solve one or two of these and compromise on the third. Dusk tries to keep all three alive at the same time.

What Segregated Byzantine Agreement Really Means

The word “segregated” is not decoration here. It explains the entire philosophy. In many Proof of Stake networks, the same people create blocks and also validate them. Over time, these actors become visible, powerful, and predictable. That predictability slowly pushes the network toward central control.

SBA breaks this cycle by splitting responsibilities. One group focuses on creating blocks.Another group focuses on validating those blocks.

These two groups are chosen differently, they do not know each other in advance, and they cannot coordinate easily. This separation reduces power concentration and makes the network harder to attack or manipulate.

Proof of Blind Bid: Competing Without Showing Your Cards

Now let me explain the most interesting part in simple words.

In normal Proof of Stake systems, big stakers are visible. Everyone knows who they are. This creates risk. If someone wants to attack the network, they already know whom to target.
Dusk removes this visibility using Proof of Blind Bid.

Instead of openly staking and waiting to be selected, a node submits a blind bid. This bid is encrypted. It proves that the node has locked enough DUSK tokens, but it does not reveal how much more it holds, and it does not reveal the identity of the node.

The system uses zero-knowledge cryptography to verify the bid. This means the network can confirm the bid is valid without seeing its details. Bigger stakes still have better chances, but nobody outside can see who is leading the race.

Only after the block is produced does the network learn who won. By then, it is already too late to interfere.
This single idea quietly removes many attack paths that exist in traditional PoS chains.

Cryptographic Sortition: Validators Appear Only When Needed

After a block is proposed, it must be validated. Dusk handles this with a second mechanism called Cryptographic Sortition. There is no fixed validator list. No public committee announced in advance.

Each eligible node runs a private check using a verifiable random function. The node locally discovers whether it has been selected to act as a validator, known as a Provisioner, for that specific moment.

If the node is selected, it sends its vote along with cryptographic proof showing that its selection was legitimate. If it is not selected, it stays silent.

This is important because attackers cannot guess who to attack. The validator group only becomes visible after it has already done its job.

Why This Design Actually Matters

When you combine Blind Bidding with Cryptographic Sortition, something powerful happens. Control is spread across time, roles, and randomness. No one can plan attacks easily. No one can dominate the system quietly. Privacy is not an add-on, it is baked into the workflow.

SBA is not designed to look flashy. It is designed to survive pressure, manipulation, and real-world financial use cases.

That is why I wanted to start this discussion. Dusk Network is not following trends. It is building infrastructure that assumes the network is hostile, competitive, and unfair by nature. And that assumption is exactly what makes its design strong.
This is not marketing. This is architecture thinking.

#dusk @Dusk $DUSK

Tôi, #MavisEvan không đến Dusk Network một cách tình cờ. Dự án này từ từ thu hút bạn, sau đó tất cả cùng một lúc. Những gì bắt đầu như một sự tò mò kỹ thuật đã trở thành một cuộc thảo luận dài và có nhiều lớp vì Dusk không được xây dựng như hầu hết các blockchain. Nó không theo đuổi sự cường điệu. Nó không hứa hẹn sự hỗn loạn được ngụy trang dưới dạng tự do. Nó được thiết kế với ý định, sự kiềm chế, và một điểm đến rất cụ thể trong tâm trí: tài chính được quản lý thực sự hoạt động trên chuỗi.

Được thành lập vào năm 2018, Dusk xuất hiện vào thời điểm mà các blockchain công cộng rất ồn ào, minh bạch đến mức quá đà, và fundamentally không tương thích với cách mà các hệ thống tài chính thực sự hoạt động. Mỗi giao dịch đều bị phơi bày. Mỗi số dư đều công khai. Mỗi chiến lược đều được phơi bày. Mô hình đó hoạt động cho việc thử nghiệm, nhưng nó sụp đổ ngay khi các tổ chức, thị trường được quản lý, hoặc tài sản thực sự xuất hiện. Tài chính, theo bản chất, yêu cầu tính riêng tư. Quy định đòi hỏi khả năng kiểm toán. Hầu hết các chuỗi chọn một trong hai hoặc không chọn cái nào. Dusk chọn cả hai.
