How CKB (Nervos Network) Works

CKB (Common Knowledge Base) is the native cryptocurrency of the Nervos Network, a layer 1 blockchain platform that aims to solve the scalability and interoperability issues prevalent in the blockchain industry. Nervos is designed to enhance decentralized applications (dApps) and offers a multi-layered protocol approach. CKB is central to the network's structure and utility, functioning to secure the network and facilitate various key mechanisms.

CKB as a Store of Value

One of the primary roles of the CKB token is to act as a decentralized store of value. It achieves this through Nervos's unique economic model, termed as “state rent.” In traditional blockchain systems, the storage of on-chain data is inefficient, leading to bloated states and congestion. To combat this, CKB introduces an economic incentive for users to either store valuable data carefully or pay for ongoing data storage. Users need to own or lock CKB tokens to occupy state storage for their smart contracts or assets—providing compensation to miners for maintaining this blockchain state over time.

Proof of Work Consensus

CKB’s layer 1 blockchain utilizes a Proof of Work (PoW) consensus mechanism, similar to Bitcoin but with some differences. PoW ensures that new transactions are securely added to the blockchain while preventing double-spending. By incorporating PoW, the network benefits from decentralized security, which is crucial for long-term data preservation.

With Nervos, PoW was selected for its security track record, although it does come with higher energy consumption compared to other consensus mechanisms like Proof of Stake (PoS). However, this choice aligns with the platform's focus on ensuring that high-value data remains secure in the long term.

CKB and Interoperability

One of the key features of Nervos is its goal to enable interoperability between different blockchains. Developers can utilize the platform to create dApps with cross-chain functionality via Nervos’s upper-layer protocols. What sets CKB apart is its use of a novel cell-based architecture that stores all on-chain assets and smart contract states in so-called “cells.” These cells make the system adaptive to future innovations and types of assets.

CKB also facilitates "Universal Application Layer" strategies, which provide the frame to support dApps across different blockchains, including Ethereum, without needing to re-architect the dApp for each individual network. This makes CKB attractive for decentralized finance (DeFi) protocols and services tasked with managing various smart assets across different blockchain environments.
