Navigating Web3 tides with focused insightsBy Alex Liu, Foresight News
As Bitcoin (BTC) price breaks through $90,000 this year and briefly challenges $100,000, market enthusiasm continues to rise. Bitcoin is no longer just synonymous with digital gold—it is becoming a key engine driving innovation in blockchain technology and the expansion of industrial ecosystems. In this context, scaling solutions, asset issuance, and ecosystem development around Bitcoin have become industry focal points. Among these, the CKB project, its RGB++ protocol, and the upcoming Fiber network are playing a pivotal role in advancing the Bitcoin financial ecosystem (BTCFi) into a new phase. This article explores how RGB++ and Fiber unlock a fresh wave of growth opportunities for BTCFi from technical, market potential, and industry impact perspectives.
The "Spillover Effect" of Bitcoin Ecosystem and the Rise of BTCFi
In the history of Bitcoin's ecosystem expansion, asset issuance has always been a challenging proposition. Bitcoin’s foundational architecture, due to its non-Turing-complete design, inherently lacks support for smart contracts. This limitation creates functional bottlenecks for many innovative asset protocols. However, as Bitcoin’s price repeatedly hits new highs, demand for Bitcoin-based assets and financial services becomes increasingly evident—creating what can be broadly termed a "spillover effect."
Insights from the Inscription Boom and Asset Issuance Demand
In early 2023, the emergence of Bitcoin inscriptions (Ordinals) demonstrated strong market demand for on-chain asset issuance. The Ordinals protocol allows users to permanently record data on the Bitcoin blockchain, sparking a boom in digital art, NFTs, and limited asset issuance. However, the inscription protocol only stores data and cannot fulfill more complex asset functionality needs. For example, while the BRC20 protocol attempts to mimic Ethereum’s ERC20 standard, its tokens lack transfer and minting capabilities, making them unsuitable for mainstream asset issuance scenarios.
In contrast, the RGB++ protocol, with its design that combines native Bitcoin integration and flexibility, has emerged as a highly anticipated solution. By introducing isomorphic binding and Leap bridgeless cross-chain technology, RGB++ enables native cross-chain functionality and flexible operations for Bitcoin assets, laying the foundation for further development of the BTCFi ecosystem.
RGB++: Redefining Bitcoin Asset Issuance
The core innovation of RGB++ lies in overcoming the limitations of the traditional RGB protocol—not only solving the programmability challenge of Bitcoin assets but also significantly enhancing issuance efficiency and liquidity.
Isomorphic Binding: Convenience of Native Assets
The traditional RGB protocol uses off-chain verification, requiring users to run clients to manage their assets—a setup prone to data silos and limiting the protocol’s applicability in decentralized finance (DeFi). RGB++’s isomorphic binding feature allows users to directly manage and operate assets using Bitcoin accounts, simplifying interaction while ensuring data transparency and interoperability.
Leap Technology: Breakthrough in Bridgeless Cross-Chain
Leap is another core component of RGB++. By deeply integrating assets with Bitcoin’s UTXO (Unspent Transaction Output) model, Leap enables seamless movement of assets between Bitcoin’s L1 mainchain and CKB’s L2 blockchain. This bridgeless cross-chain approach reduces technical complexity, transaction costs, and associated risks.
RGB++'s architectural design introduces a new paradigm for asset issuance and circulation within the Bitcoin ecosystem. Its flexibility and efficiency have already been validated by the market and attracted attention and support from multiple key players in the Bitcoin space.
Fiber: Igniting the Spark for BTCFi Markets
The Fiber network, developed by the CKB team, is the next-generation public lightning network tailored for payment demands in the Bitcoin ecosystem. It enables fast, low-cost, and decentralized multi-currency payments and peer-to-peer transactions for RGB++ assets. Scheduled to launch in mid-December, Fiber will not only meet high-speed payment needs for Bitcoin assets but also provide critical infrastructure for decentralized applications (DApps).
High-Performance Payment Network
Fiber introduces more efficient off-chain channels supporting multi-currency payments and P2P transactions, dramatically improving transaction throughput and cost-efficiency for RGB++ assets. This capability strongly supports DeFi applications and NFT (in RGB++, called DOB) trading within the Bitcoin ecosystem, enabling rapid circulation of RGB++ assets on the Fiber network.
Decentralization and Scalability
Unlike traditional on-chain scaling solutions, Fiber adopts a decentralized architecture whose scalability can accommodate growing future transaction volumes. Additionally, Fiber is compatible with Bitcoin’s Lightning Network, allowing RGB++ assets to integrate seamlessly into Bitcoin’s existing payment ecosystem and expand their application scope.
CKB's Advantages in the Global BTCFi Race
In the global competition for BTCFi dominance, Eastern and Western approaches each have strengths—and notable weaknesses:
-
Eastern solutions like Runes and Ordinals innovate rapidly but lack robust infrastructure and mature ecosystems.
-
Western protocols such as RGB and Taproot started earlier but have progressed slowly, lacking effective market adoption.
In contrast, CKB demonstrates comprehensive competitive advantages across technology, ecosystem maturity, and real-world market deployment:
-
