📍It’s not enough to just build a cross-chain bridge, we need to be a “bridge construction team”丨deBridge project one-page report

With the launch of Layerzero, although its “insulting airdrop” and compulsory donation operations have been criticized by the community, we have to face up to the rigid demand for cross-chain interoperability for the current multi-chain market structure

Based on this topic, this article will expand on deBridge and my more views on the cross-chain bridge business

🗝️Report outline

1. Principles and basic classification of cross-chain bridges

2. Structural framework and business analysis of deBridge

3. Application case-DLN

4. The way to break through the cross-chain business

deBridge is a cross-chain logic that adopts off-chain verification + on-chain call. The off-chain part is currently composed of more than ten validator nodes to allow basic assets to be cross-chain verified It can be turned and run normally

The part on the chain is the contract deployed between multiple chains, which is the core of why the "bridge" is called a "bridge"

In fact, this is also the basic component of the mainstream cross-chain bridge: multi-chain contracts on the chain + validator nodes

Not only is the structure simple, but for a cross-chain facility, its business model is also very simple: because the definition of the bridge itself has the meaning of "middle party", so for each cross-chain protocol, basically it is to make a profit by charging a small fee for transactions between chains

Asset cross-chain, custody and message transmission are the application directions that deBridge and mainstream cross-chain facilities need to overcome. In order to make it easier for readers to understand, this article uses the example of cross-chain asset transfer. In fact, in the process of message transmission, a fee will also be charged

Half of these fees are transferred to the deBridge treasury controlled by governance. The other half is converted into ETH and used to pay validators and their principals. Each expenditure is evenly distributed to all active validators (according to the recent official blog, the current daily protocol income is about $100,000)

There is also an airdrop activity for accumulating points to participate in, which will be used for the token airdrop plan. For example, you can experience participation as shown in #Layerzero . You can accumulate 100 points for each $1 cross-chain transaction: https://app.debridge.finance/r/28525
