What is RGB++? A complete understanding of RGB++ in one article

One of the main reasons why the Bitcoin Layer 2 track continues to be popular is the continuous improvement of technology. A groundbreaking solution RGB has been proposed before. This RGB is still relatively unfamiliar to many people, and they don’t even know what RGB is? It is understood that RGB is an extension protocol that uses one-time seals and client verification technology to manage state changes and transaction verification, aiming to provide a decentralized financial (DeFi) solution. Some people may not understand the simple introduction. Let me give you a detailed introduction so that you can fully understand RGB in one article.

What is RGB?

RGB is an extended protocol based on the RGB principle. RGB inherits the core idea of ​​the RGB protocol and adopts different virtual machines and verification schemes. Users do not need an independent RGB client and only need to access Bitcoin and CKB light The node can complete all verification independently. RGB can also bring Turing-complete contract expansion and dozens of times performance expansion to Bitcoin. It does not use any cross-chain bridge, but uses a native client verification scheme to ensure security and censorship resistance.

RGB utilizes single-use seals and client-side verification technology to manage state changes and transaction verification. It maps Bitcoin UTXO to NervosCKB's Cell through isomorphic binding, and uses script constraints on the CKB chain and Bitcoin chain to verify the correctness of state calculations and the validity of changed ownership.

RGB solves the technical problems of the original RGB protocol in actual implementation, and provides more possibilities, such as blockchain-enhanced client verification, transaction folding, shared state and ownerless contracts, non- Interactive transfers, etc. It brings Turing-complete contract expansion and performance expansion to Bitcoin without the need for cross-chains or loss of security.

Is RGB an upgrade of RGB?

RGB is not based on the improvement and optimization of the RGB protocol, but draws on the ideas of RGB and adds an existing independent blockchain to implement BTC Smart contract solution. Specifically, RGB has learned two core points of RGB. The one-time seal is similar to RGB, allowing the BTC main network to store important data, while the client verification is replaced by the CKB chain, allowing it to do public database and off-chain Settlement layer. In essence, RGB is a BTC side chain (CKB) transformed into L2 of BTC, and then borrows the technology and name of RGB.

RGB’s trick on the name was criticized by the founder of RGB on Twitter, directly saying that it is a scam, which is a very serious characterization. But as competing products to a certain extent, the concepts are different. It is normal for RGB not to like RGB. However, the first sentence of the RGB white paper is that RGB is an extended protocol based on RGB. It is easy for users who do not understand the technology to mistakenly think that this is an upgraded version of RGB or even a product of the same team. It cannot be said that it is unfair to be accused of a scam.

The core difference between RGB and RGB is that RGB uses its own CKB chain. The advantage of this is that the scalability and flexibility will definitely be greater, which means that it should be faster to make smart contracts that can engage in DeFi. The downside is that decentralization is significantly worse, which is very important to some BTC holders.

RGB inherits the core idea of ​​the RGB protocol and adopts different virtual machines and verification schemes. Users do not need an independent RGB client. They only need to access Bitcoin and CKB light nodes to complete all verifications independently. RGB brings Turing-complete contract extensions and dozens of times performance expansion to Bitcoin. It does not use any cross-chain bridge, but uses a native client verification scheme to ensure security and censorship resistance. As the technology continues to improve, RGB applications will be recognized by more and more people and widely used. .
