Nervos Network (CKB): 6 Must-Know Facts | Bitcoin Layer 2 & RGB++ Protocol 2025

A deep dive into Nervos Network, the multi-layer blockchain solving the interoperability trilemma with a unique architecture designed for a truly decentralized and universal application ecosystem.

I. Project Overview

The Nervos Network is a multi-layered, open-source, public blockchain ecosystem designed to address the “blockchain trilemma”—the challenge of achieving decentralization, security, and scalability simultaneously. Launched in 2019, Nervos takes a unique architectural approach by separating these concerns across different layers. Its foundational layer, Layer 1, is the Common Knowledge Base (CKB), a proof-of-work (PoW) blockchain optimized for security and decentralization, acting as the public trust root for the entire network.

The core philosophy of Nervos is that a single blockchain cannot efficiently handle all the needs of a burgeoning Web3 world. Instead, the CKB layer provides ultimate security and asset preservation, while Layer 2 solutions are expected to handle high-performance transactions and complex computations. This layered design allows for immense flexibility, enabling developers to build applications with the optimal trade-offs for their specific use case without compromising the security of the core ledger.

At the heart of the Nervos Network is its native token, the CKByte (CKB). It serves a dual purpose: enabling users to store assets and execute smart contracts on the CKB blockchain and providing a sustainable economic model for the network’s long-term operation. A key differentiator for Nervos is its focus on state-based, generalized smart contracts through its Cell Model, which offers a more flexible and scalable alternative to the account-based model used by Ethereum. This design, combined with its recent focus on Bitcoin interoperability via the RGB++ protocol, positions the Nervos Network as a versatile and forward-thinking infrastructure project.

II. Token Metrics

The CKB token is the lifeblood of the Nervos Network, providing access to the blockchain’s state storage and incentivizing miners to secure the network. Its market performance reflects the overall interest and adoption of the ecosystem.

III. Token Economics

The tokenomics of the Nervos Network’s CKB token are designed for long-term sustainability and to align the interests of users, developers, and miners. The model revolves around the concept of state storage and a “store of value” approach for the base layer.

The Role of CKByte (CKB)

The primary utility of the CKB token is to represent ownership of state on the CKB blockchain. One CKB token entitles the holder to store one byte of data on the Layer 1 chain. For example, if a user wants to create a token that occupies 150 bytes of state, they must lock up 150 CKB. This CKB remains locked as long as the data is stored on-chain and is released back to the user when the data is removed. This creates a direct link between the token’s value and the demand for the network’s storage capacity.

Economic Model and Inflation

Nervos has a two-part inflation model:

1. Base Issuance: This follows a “halving” schedule similar to Bitcoin, with rewards for miners decreasing by half approximately every four years. This issuance is finite and will eventually cease.
2. Secondary Issuance: A constant 1.344 billion CKB are issued annually. This issuance is designed to create a “state rent” system. It is distributed to miners, long-term holders who lock their CKB in the Nervos DAO, and a treasury fund. Users who are actively using their CKB to store state do not receive these rewards, effectively making them pay for their state storage over time through the dilution of their holdings. This incentivizes users to be efficient with their use of the precious Layer 1 state and ensures miners are compensated for securing the network indefinitely, even after the base issuance runs out.

Nervos DAO

The Nervos DAO is a smart contract that allows CKB holders to lock their tokens to receive a portion of the secondary issuance rewards. This mechanism serves as a hedge against the dilution from secondary issuance for long-term holders who are not actively using their CKB for state storage. It aligns incentives by rewarding those who are committed to the network’s long-term value.

IV. Technical Features and Development Status

The Nervos Network’s architecture is its most defining characteristic, designed with flexibility and interoperability as first principles.

Key Technical Features:

• Layered Architecture: Nervos separates computation (Layer 2) from state verification (Layer 1). The CKB base layer is a secure, PoW-secured public ledger, while high-throughput transactions and dApps can run on various Layer 2 protocols that connect to it.
• The Cell Model: Unlike Ethereum’s account-based model, Nervos uses the Cell Model, which is a generalization of Bitcoin’s UTXO model. A “Cell” is a data structure that can contain any arbitrary data and scripts. This model is highly flexible and parallelizable, allowing for more efficient transaction processing and avoiding certain scalability bottlenecks found in the account model.
• CKB-VM (Virtual Machine): The CKB-VM is a high-performance virtual machine that executes smart contracts on the network. It is based on the open-standard RISC-V instruction set, which means developers can write smart contracts in a wide variety of popular programming languages (like C, C++, and Rust) rather than being limited to a blockchain-specific language like Solidity.
• RGB++ Protocol: This is a major recent development that extends the Bitcoin-native RGB protocol. RGB++ allows for the seamless transfer and management of Bitcoin-based assets (like Ordinals and Atomicals) and smart contract capabilities without needing to use a cross-chain bridge. It achieves this by mapping Bitcoin UTXOs to Nervos CKB Cells, using the CKB network for smart contract execution and transaction verification, while leveraging Bitcoin’s PoW security. This innovation positions the Nervos Network as a leading contender for a Bitcoin Layer 2 solution.

The Nervos development team has a strong track record of shipping complex technical solutions. The mainnet has been running securely since 2019, and the recent focus on the RGB++ protocol and the broader “Bitcoin KB” vision shows a clear and innovative path forward.

V. Market Analysis

Nervos Network competes in a crowded market of Layer 1 blockchains and interoperability solutions. Its unique architecture places it in a distinct category, but it faces competition from multiple fronts.

Main Competitors:

• Ethereum (ETH): As the dominant smart contract platform, Ethereum is the primary competitor for all Layer 1s. Its vast network effect, developer community, and DeFi ecosystem are formidable. Nervos competes by offering a different scalability philosophy (layered vs. integrated) and a potentially more sustainable economic model.
• Cardano (ADA): Cardano also uses a UTXO-based model (EUTXO) and emphasizes a research-driven, methodical approach to development. Both projects prioritize security and sustainability. Cardano has a larger community and market capitalization, but Nervos’s CKB-VM offers greater language flexibility for developers.
• Bitcoin Layer 2 Solutions (e.g., Stacks, Rootstock): With its new focus on Bitcoin interoperability through RGB++, Nervos now directly competes with projects aiming to bring smart contract functionality to Bitcoin. Stacks uses its own security mechanism (Proof-of-Transfer), while Nervos aims for a more integrated approach that leverages Bitcoin’s native security and asset definitions. Nervos’s key advantage here is its ability to offer complex smart contract functionality without requiring a hard fork or bridge for Bitcoin assets.
• Interoperability Platforms (e.g., Cosmos, Polkadot): These platforms also aim to create an ecosystem of interconnected blockchains. However, they focus on enabling sovereign chains to communicate, whereas Nervos provides a universal security and trust layer that other chains can anchor to.

Competitive Advantage:

1. Sustainable Economic Model: The CKB tokenomics with its state rent mechanism are designed to ensure the network’s security and financial viability for the very long term.
2. Flexibility and Generalization: The Cell Model and RISC-V based CKB-VM provide developers with unparalleled flexibility, moving beyond the constraints of the EVM.
3. Innovative Bitcoin Interoperability: The RGB++ protocol is a game-changer, offering a highly secure and seamless way to build on Bitcoin that few competitors can match. This gives CKB a strong narrative and a clear use case in the largest crypto ecosystem.
4. First-Principles Design: Nervos was built from the ground up to solve the blockchain trilemma through its layered approach, which may prove to be a more scalable and enduring design in the long run.
