When the RGB++ protocol was first launched, the market was very enthusiastic. The first use case of the “isomorphic binding” technology proposed by RGB++ combined the BTC network and the CKB network, which also triggered people’s new understanding of the CKB network.

After CKB launched the Bitcoin layer 1 asset issuance protocol RGB++ in the first half of the year, it has now launched CKB RGB++ Layer, which will not only ignite Bitcoin Finance (BTCFi), but may also drive all UTXO chains to take off.

Fiber Network is a next-generation public lightning network built on Nervos CKB and off-chain channels, which can provide fast, low-cost and decentralized multi-currency payments and peer-to-peer transactions for RGB++ assets.

Nervos Network expands on Bitcoin’s core technology, powering Bitcoin Layer 2 (L2) with a scalable layer of blockchain.

Cipher, co-founder of CKB and proposer of RGB++, talked about the unique significance of RGB++ Layer and UTXO model to BTCFi, and some questions and opinions about CKB and Bitcoin ecology.

Since the AA narrative became popular in the Ethereum community in 2022, the concept of account abstraction has become popular in the Web3 community.

On August 23, CKB released its Lightning Network Fiber Network light paper. Recently, I have been studying the Lightning Network in depth and have gained some insights, so I conducted research on Fiber as soon as possible and wrote this article.

CKB's Fiber has upgraded the traditional Lightning Network and made many improvements to the latter.

The Bitcoin ecosystem has been silent recently, including CKB, STX, etc. Is it because all the funds have gone to speculate on the Ethereum ecosystem?

Let’s talk about RGB++ and CKB, the dark horse of this bull market, to explore the relationship between RGB++ and RGB, and why RGB++ should be upgraded to RGB++ Layer.
