Background:

The explosive popularity of inscriptions last year has drawn many people to focus on the BTC ecosystem. People have begun to reassess the enormous potential of the BTC ecosystem, and how to unleash the potential of the trillion-dollar BTC market value has become a question many are pondering. At the same time, the explosive popularity of the BTC ecosystem has also laid bare issues such as high BTC gas fees and slow confirmations. People have started to extend the question of how to develop the BTC ecosystem better, faster, and cheaper through inscriptions. BTC Layer2 has become the choice for many institutions, exchanges, users, and builders.

However, looking back at history, one will find that there were already projects focused on this track in 2018. Improving the scalability of BTC was a topic that had been researched back in 2018. This project is Nervos Network.

Of course, many new users may not be very familiar with this established BTC ecosystem leading project. Let me briefly introduce it: it has raised over 100 million USD, is listed on Binance, and the RGB++ protocol is proposed by Cipher Wang, co-founder of Nervos, leading CELL Studio.

POW security

Hashrate is a measure of the basic computational power of PoW blockchain miners. Therefore, hashrate represents the security of the CKB network. In 2024, the total hashrate of the CKB network continues to break historical records. As of today, the total hashrate of CKB has reached 423PH/s, which is the highest hashrate value in the history of the CKB network.

The CKB customized NC-MAX consensus protocol adjusts mining difficulty approximately every four hours based on the network's orphan block rate. This way, the network can optimize block time while reducing the possibility of block reorganization, as block reorganization can undermine network stability.

The security model of CKB aims to create a positive feedback loop: the more value stored on the chain, the higher the security of the network; the higher the security, the more value it attracts for storage.

RGB++
RGB++ proposed by Nervos Network is a true 'chain' that can be combined with all UTXO chains, creating a universal, cross-chain interoperable UTXO intermediary layer that can index any Turing-complete UTXO chain.

In addition, assets from any UTXO chains such as BTC, CKB, BSV, BCH can enter the RGB++ ecosystem, allowing various inscriptions, runes, and other assets to be transformed into assets on the RGB++ Layer. Other UTXOs can also enter the RGB++ ecosystem: for example, Ethereum's execution layer modular Layer2 Fuel and the established Layer1 public chain Cardano.

The characteristic of RGB++ using UTXO isomorphism binding means that the interaction between the two chains occurs completely in a 1:1 manner, with no notion of 'cross-chain.' Your operations on Layer2 will directly impact Layer1, thus based on the UTXO model, RGB++ Layer can serve as a 'bridge-less' cross-chain bridge, enabling interoperability and asset liquidity across all UTXO chains. As asset content becomes richer and liquidity accumulates, it turns barren soil fertile, creating prerequisites for more Bitcoin DeFi applications in the future.

Through our understanding of the above content, we can summarize that RGB++ has the following advantages:

1. Turing complete, low entry threshold for ecosystem development.

2. The entry threshold for other chain ecosystems is also relatively low.

3. BTC assets can interact directly with assets on the CKB chain without cross-chain operations.

Ecosystem situation

The main ecosystem website currently is https://www.rgbppeco.xyz/

According to ecosystem inquiries, nearly 30 projects have chosen to deploy in the RGB++ ecosystem, among which JoyID, .bit, nervape, UTXO Stack, etc., are well-known web3 projects that everyone can continue to follow.

I believe that with the improvement of infrastructure, the richness and quality of projects will have qualitative advancements and leaps. I personally hold several of the aforementioned ecosystem projects.

Conclusion:

Currently, Bitcoin Layer2 mainly consists of the 'EVM camp' and the 'UTXO camp.' The 'UTXO camp,' led by CKB, holds a technical advantage due to its complete isomorphism with BTC (based on PoW+UTXO) and the recognition of expansion protocols like RGB within the Bitcoin community, allowing for Turing-complete contract expansion and performance enhancement without cross-chain operations or loss of security.

Looking forward to CKB + RGB++ bringing a new wave of BTC ecosystem enthusiasm.
