📝 Hi, I am 𝟏𝟎. In the evolution of Bitcoin, how does Nervos CKB become a new continent in the Bitcoin ecosystem?

The success of Bitcoin is evident, and Nervos CKB ( @CKB Eco Fund ) is quietly rising as the 'secret weapon' of the Bitcoin ecosystem. By expanding Bitcoin's usability, #CKB助力比特币生态 injects new vitality.

I. Introduction to the Nervos CKB Project

1. What is Nervos CKB

Nervos CKB is a public chain based on the PoW + UTXO model, fully compatible with Bitcoin, aiming to provide cross-chain interoperability and scalability support for the Bitcoin ecosystem. Imagine, $CKB acts like Bitcoin's 'expander', mapping Bitcoin's UTXO into CKB's Cell through the RGB++ protocol, enabling smart contract functionality and allowing Bitcoin assets to transact across chains seamlessly.

CKB also expands the Bitcoin ecosystem through the Fiber Network, facilitating the circulation of various assets in the Lightning Network, thereby enhancing the experience of decentralized payments. Since its mainnet launch in 2019, CKB has continuously promoted the widespread application of the Lightning Network and completed its first mining output halving in November 2023, optimizing its economic model.

2. Team Background and Financing

The founding team of Nervos Network has extensive experience in the blockchain industry. Chief Architect Jan Xie participated in the development of the Ethereum Ruby-ethereum and pyethereum clients and collaborated with Vitalik Buterin to create the Casper consensus and sharding technology, later founding Cryptape, which focuses on underlying blockchain technology.

Co-founder Kevin Wang previously worked at IBM's Silicon Valley lab, later co-founding the Launch School for software engineers and participating in the development of Khalani.

Co-founder and COO Daniel Lv is a co-founder of the Ethereum wallet imToken and has also served as the CTO of Yunbi exchange, organizing the Ruby China community for 10 years.

In August 2018, Nervos Network completed a financing round of $28 million, with investors including Polychain Capital and Sequoia China. On October 16, 2019, they successfully raised $72 million on Coinlist.

II. CKB: A Unique Layer 2 for Bitcoin Expansion

Since its launch, CKB has adopted the same PoW consensus mechanism as Bitcoin, ensuring security and decentralization. In November 2023, CKB achieved its first mining output halving, successfully reducing the inflation rate and optimizing its economic model. All of this is thanks to its independently developed Eaglesong mining algorithm, which perfectly combines with Bitmain's mining machines, enhancing mining efficiency.

In terms of programming capability, CKB's Cell model innovates on the traditional UTXO, allowing each Cell to accommodate more complex data structures and functions. Through LockScript and TypeScript, developers can implement Covenant features that Bitcoin does not yet possess, greatly expanding the possibilities for applications.

The user experience is also excellent, as the CKB mainnet is perfectly compatible with BTC addresses (bc1p and bc1q), allowing Bitcoin users to easily transition to the CKB ecosystem. The JoyID wallet does not require a mnemonic phrase, making it simple and convenient, with users not having to worry about frequently switching wallets.

CKB has also introduced the Axon framework, supporting Bitcoin inscriptions to create their own Layer 3 on CKB, continuously optimizing the infrastructure. The tool Kuai, developed in collaboration with the MagickBase team, has also lowered the barrier for DApp development, allowing more developers to easily participate.

III. RGB++: CKB's Innovative Expansion Protocol

On February 13 this year, the CKB official website released the RGB++ light paper and successfully launched the mainnet within just two months. RGB++ combines Bitcoin's UTXO model with CKB's underlying architecture to achieve seamless data mapping, solving the data island problem in the RGB protocol. The good news is that users do not need to download any additional clients; they can complete verification easily through Bitcoin and CKB light nodes.

Unlike other sidechains or EVM staking solutions, RGB++ relies on BTC's PoW + UTXO characteristics and the widespread recognition of the RGB protocol, providing a secure and efficient asset issuance method. CKB serves as the execution layer, supporting Turing-complete contracts that go beyond existing EVM limitations. RGB++ enhances transaction efficiency through isomorphic binding, simplifies user experience, and addresses the complex interaction requirements within the RGB protocol.

IV. Summary

Since its launch in 2019, Nervos CKB has successfully positioned itself as a Bitcoin L2, leveraging the PoW + UTXO isomorphic blockchain architecture. The team is experienced and has made innovations in programmability and scalability, launching concepts like RGB++ and DOB in 2024, aligning with the current trends in BTC L2 development.

Today, the Nervos ecosystem is gradually taking shape, and community engagement is noteworthy. As a BTC L2, its core goal is to enhance the convenience of Bitcoin applications and asset liquidity.

CKB seized the opportunity in the Bitcoin L2 ecosystem, quickly rising as a technological pioneer. Although its development speed is not as rapid as other BTC L2s, CKB is expected to play an important role in the Bitcoin ecosystem due to its technological advantages, hinting at its long-term value.
