The Cell model of CKB is an improvement on the Bitcoin UTXO accounting model, allowing for more flexible data storage and verification. Through the dual script (Lock Script and Type Script) mechanism, it supports more functionalities, with each Cell capable of storing different types of data, such as tokens, smart contracts, and application states, and able to operate independently, enhancing scalability.
2. CKB - VM
CKB - VM is the execution engine of $CKB that uses the RISC - V instruction set, compatible with various programming languages, including C, Rust, etc. It features predictable gas costs, secure execution, and efficient integration with the Cell model, providing convenience for developers to create complex decentralized applications.
3. Core Technology Analysis
(1) JoyID
1. Technical Features and Application Scenarios
JoyID, as the first Passkey wallet to support the Lightning Network, utilizes biometric technology to provide identity verification services for users. It supports multiple networks, including Ethereum, Bitcoin, and RGB++ assets, enhancing users' control over their identities and assets in the decentralized Bitcoin ecosystem, and improving the convenience of cross-network interactions. For example, users can transfer Bitcoin and Ethereum assets without complex conversion processes.
2. Impact on Lightning Network Applications
In Lightning Network applications, JoyID's rapid identity verification feature can significantly enhance transaction speed. Especially in micro-payment and cross-border remittance scenarios, users can quickly complete payment authorization through biometric recognition, achieving near-instant transaction confirmation and optimizing user experience.
(2) Fiber Network
1. Technical Architecture and Features
Fiber Network is a cross-chain network that enhances the liquidity and scalability of the BTCFi ecosystem, enabling seamless circulation of multiple assets across different blockchains, thereby enhancing the stability and usability of decentralized financial networks.
2. Role in the Bitcoin Ecosystem
In the Bitcoin ecosystem, Fiber Network addresses the key issue of asset cross-chain circulation, expanding the liquidity of Bitcoin assets, allowing interaction with more types of assets, and enriching application scenarios. At the same time, its decentralized design avoids the centralization risks of traditional cross-chain solutions, aligning with the core values of Bitcoin and strengthening the foundation of the decentralized Bitcoin ecosystem.
3. Potential for Programmability Expansion
Fiber Network provides a vast space for programmability expansion, supporting the development of more complex smart contracts and cross-chain applications. Developers can leverage its cross-chain capabilities to combine functionalities and assets across different blockchains, creating diverse applications such as cross-chain financial products and cross-chain games.
(3) RGB++
1. Protocol Principles and Innovations
RGB++ is an asset issuance protocol based on the original RGB protocol, using CKB as Bitcoin's data availability and execution layer. Through isomorphic binding technology, it maps Bitcoin UTXOs to CKB Cells, achieving seamless integration with CKB's Turing-complete smart contracts. This not only enables bridge-less cross-chain transactions of Bitcoin assets but also introduces on-chain verification of key transaction elements, enhancing security and data availability.
2. Value to the Decentralized Bitcoin Ecosystem
In the decentralized Bitcoin ecosystem, RGB++ enriches the asset issuance model for Bitcoin, allowing project teams to issue more types of assets without changing the Bitcoin mainnet, catering to different needs. For example, the Initial Bitcoin Offering (IBO) model brings more financial products to BTCFi, attracting more users. At the same time, RGB++ enhances interoperability between the Bitcoin ecosystem and other blockchain ecosystems, breaking down barriers between assets and functionalities, and promoting collaborative development.
3. Role in Lightning Network Applications and Programmability Expansion
Combined with the Lightning Network, RGB++ can enable more complex Lightning Network applications, such as using issued assets for payments, increasing payment flexibility and diversity, and adding more conditions and logic to transactions through smart contracts, enhancing transaction security and efficiency. As a key technology for programmability expansion, RGB++ provides Bitcoin developers with more tools to create more complex smart contracts, transforming Bitcoin into a programmable platform with rich application scenarios.
