Nervos Network (CKB) - Blockchain Guide

Introduction to Nervos Network

Nervos Network takes a contrarian approach in an ecosystem dominated by Proof-of-Stake chains. By embracing Proof of Work and the UTXO model—Bitcoin’s foundational choices—Nervos argues that long-term security and decentralization require these battle-tested mechanisms, with scalability achieved through layers rather than base-chain compromises.

The Common Knowledge Base (CKB) serves as the secure Layer 1, designed specifically for value storage and verification. Like Bitcoin maximalists argue for BTC, Nervos believes the base layer should optimize for security, with performance and features handled by Layer 2 solutions.

How Nervos Works

Layered Architecture

Design philosophy:

Layer 1 (CKB): Security and settlement
Layer 2: Performance and features
Each layer optimized for its purpose
Composability between layers

Cell Model

UTXO evolution:

Cells contain data and state
Programmable UTXO
More flexible than Bitcoin
State rent mechanism

Proof of Work

Security choice:

NC-MAX consensus
ASIC-resistant initially
Now ASIC-friendly
Bitcoin-aligned security model

Technical Specifications

Conclusion

Nervos represents a thoughtful bet on Bitcoin-aligned principles applied to smart contract platforms. The Proof of Work consensus, UTXO-based cell model, and state rent economics reflect genuine technical conviction rather than following trends.

RGB++ and Bitcoin integration could prove prescient as Bitcoin’s ecosystem expands. However, going against the dominant Proof-of-Stake narrative means swimming upstream against market preferences and ESG concerns.

For developers seeking a secure, UTXO-based smart contract platform with strong Bitcoin integration, Nervos offers unique capabilities. The challenge remains building ecosystem momentum in a market that has largely decided PoS is the future—a conclusion Nervos deliberately challenges.
