What Is Nervos Network?
Nervos Network is a UTXO-based Layer 1 blockchain using an extended UTXO model called the Cell model, designed to be the secure base layer for a multi-layer blockchain ecosystem. Unlike Ethereum's account model (where state is stored in contract accounts), Nervos' Cell model stores all state in discrete "cells" — similar to Bitcoin's UTXOs but with arbitrary data storage capability. Cells can contain tokens, smart contract scripts, or any structured data, with their modification or destruction governed by the scripts they contain. This UTXO-derived architecture provides first-class asset ownership semantics — every asset's existence is explicit in the cell that contains it — reducing the counterintuitive behaviour of Ethereum's account model where asset existence is implied by contract state.
Nervos Network secures its base layer through proof-of-work (Eaglesong algorithm) while enabling smart contracts through CKB-VM — a RISC-V based virtual machine that supports any programming language compiled to RISC-V. CKB-VM's RISC-V foundation means developers can write smart contracts in C, Rust, or any RISC-V-compatible language, providing flexibility beyond EVM's Solidity constraint.
RGB++ Protocol: Bitcoin Asset Issuance on CKB
The most significant recent development for Nervos is the RGB++ protocol — an extension of Bitcoin's RGB protocol that uses CKB as the verification layer for Bitcoin-issued assets. RGB++ allows fungible tokens, NFTs, and DeFi applications to be issued on Bitcoin's UTXO model (inheriting Bitcoin's security) with their logic and state verified by CKB's smart contracts. This creates native Bitcoin DeFi — assets issued on Bitcoin, interacting with DeFi protocols whose logic is enforced by CKB's programmable layer. The result is a form of Bitcoin Layer 2 that uses Bitcoin's UTXO model for asset issuance and CKB's Cell model for verification, without requiring new chains or trust assumptions beyond Bitcoin and CKB's respective PoW security. Compare RGB++ to ZetaChain's approach to Bitcoin DeFi as an alternative architecture for the same market opportunity. Monitor RGB++ asset issuance volume and CKB verification transaction count as adoption metrics.
CKB Token: State Rent and Store of Value
CKB's tokenomics include a state rent mechanism: storing data on Nervos' base layer requires holding CKB proportional to the data size. Developers who want persistent smart contract state must hold CKB; releasing state returns CKB. This state rent model aligns incentives between network participants and ensures the base layer is not filled with unclaimed or spam state. CKB is mined (PoW) with a halving schedule similar to Bitcoin's, creating a deflationary mining supply. Secondary issuance (an additional inflation layer) deposits CKB into a Nervos DAO that distributes it to CKB holders who lock tokens — mitigating secondary inflation for long-term holders. Understanding CKB's tokenomics requires grasping both primary issuance (mining), secondary issuance (inflation for state compensation), and Nervos DAO redistribution.

Nervos DAO and Long-Term Holding
The Nervos DAO allows CKB holders to lock tokens and receive a proportional share of secondary issuance — effectively protecting long-term holders from inflation dilution. By locking in the Nervos DAO, holders earn secondary issuance rewards that offset the inflationary effect of secondary issuance on non-locking holders. This creates a bifurcated holder dynamic: active CKB used for state storage pays the implicit state rent (secondary inflation dilutes their value); CKB locked in Nervos DAO is protected from inflation. For investors, the Nervos DAO lock is the optimal passive holding strategy for CKB not actively used in applications. Monitor Nervos DAO lock ratio and compare CKB staking yield against other PoW infrastructure tokens for baseline comparison.
Investment Considerations
CKB's investment thesis is significantly enhanced by the RGB++ Bitcoin DeFi narrative — connecting Nervos to the large and growing Bitcoin ecosystem through a novel technical approach. The PoW security model and UTXO architecture align CKB with Bitcoin-native investors who value these properties. Key risks include the complexity of the Cell model limiting developer adoption, and competition in the Bitcoin DeFi space from other approaches. Apply position sizing discipline and monitor RGB++ adoption metrics.
CKB's Multi-Layer Architecture Vision
Nervos Network's original architecture vision was a layered system: the CKB base layer providing maximum security and asset custody, with Layer 2 networks (payment channels, state channels, and optimistic rollups) built on top for high-throughput, low-cost interactions. The base layer's focus on security and asset custody (rather than computational throughput) intentionally limits its direct TPS while enabling faster, more efficient upper layers. This is philosophically similar to Bitcoin's layered approach (Lightning Network on top of Bitcoin) — prioritising base layer security above base layer scalability. CKB's Cell model is particularly well-suited for Layer 2 interaction: Layer 2 state roots can be stored as cells on CKB and verified by CKB scripts, providing efficient Layer 2 fraud proof or validity proof anchoring without requiring CKB to execute Layer 2 logic directly.
The RGB++ protocol's success in bringing Bitcoin asset issuance to CKB represents the most significant external ecosystem integration in Nervos' history. RGB++ issuers choose CKB as their verification layer precisely because CKB's UTXO-compatible Cell model integrates naturally with Bitcoin's UTXO model — the same design philosophy that made Bitcoin UTXO the standard for digital asset ownership. As the Bitcoin DeFi ecosystem grows (driven by interest in Bitcoin Layer 2s, Ordinals, and native Bitcoin yield), CKB's position as the verification layer for RGB++ assets becomes increasingly valuable. Track the number of RGB++ token issuances on Bitcoin verified by CKB as the primary indicator of this adoption vector. Monitor CKB Nervos DAO lock ratio for long-term holder confidence signal.

CKB's long-term investment case benefits from the Bitcoin DeFi narrative's growth trajectory. As Bitcoin continues to attract institutional allocation and the ecosystem around Bitcoin expands beyond simple HODL strategies, the demand for Bitcoin-native DeFi infrastructure grows. RGB++'s position as the leading Bitcoin asset verification protocol on CKB gives Nervos direct exposure to this trend. Investors who are constructive on the Bitcoin ecosystem's expansion should consider CKB as a complementary position — providing exposure to Bitcoin DeFi development without the direct BTC price risk of holding Bitcoin itself.
