Nervos Network (Common Knowledge Base) is a proof-of-work Layer 1 that uses a generalized UTXO model called the Cell Model — making it uniquely compatible with Bitcoin's architecture. This positioned Nervos as a key player in the Bitcoin ecosystem when the RGB++ protocol enabled Bitcoin-native asset issuance and smart contracts to settle on Nervos's flexible CKB layer. The Cell Model extends Bitcoin's UTXO concept to support arbitrary data and computation. Just as Bitcoin UTXOs track ownership of BTC, Nervos Cells can track ownership of any digital asset with custom verification rules. This makes Nervos a natural extension of Bitcoin rather than a competitor — enhancing Bitcoin's capabilities without modifying Bitcoin itself. CKByte (CKB), the native token, has a unique economic model: it represents storage space on the blockchain. Holding 1 CKB gives you the right to store 1 byte of state data on-chain. This 'state rent' model prevents state bloat and creates fundamental demand for CKB proportional to blockchain storage usage.
Nervos launched CKB mainnet in November 2019 with PoW mining. The network operated quietly as an infrastructure layer until RGB++ ignited interest by enabling Bitcoin-native asset issuance. SEAL (Spore Protocol) enabled Bitcoin NFTs to settle on Nervos. The Bitcoin ecosystem narrative (ordinals, BRC-20s, runes) brought renewed attention to Nervos as complementary Bitcoin infrastructure.
Nervos uses a two-layer architecture: Layer 1 (CKB) provides security and decentralization through PoW mining; Layer 2 solutions handle scaling and application logic. The Cell Model stores data in Cells (like Bitcoin UTXOs but more flexible), where each Cell has a capacity (in CKB), data, and a lock script that defines who can modify it. RGB++ leverages Nervos's Cell Model to provide smart contract functionality for Bitcoin assets. Bitcoin transactions commit to Nervos Cells, enabling complex operations (DeFi, NFTs, DAOs) while settling on Bitcoin for security. This makes Nervos the smart contract extension layer for Bitcoin.
CKB has base issuance (PoW mining rewards, decreasing with halvings) and secondary issuance (constant rate targeting state rent). Primary issuance goes to miners; secondary issuance goes to miners, NervosDAO depositors, and the treasury. NervosDAO provides inflation protection — depositors earn secondary issuance proportionally, offsetting dilution.
The Cell Model's UTXO extension makes Nervos the most natural smart contract layer for Bitcoin.
Enabling Bitcoin-native assets and smart contracts to settle on Nervos creates unique value in the Bitcoin ecosystem.
CKB-as-storage creates fundamental demand proportional to blockchain usage — not just speculation.
Proof-of-work provides censorship resistance and security aligned with Bitcoin's philosophy.
Bitcoin Layer 2 / extension layer is a specific thesis that depends on Bitcoin ecosystem growth.
Nervos's DeFi TVL and dApp ecosystem are minimal compared to established smart contract platforms.
Dual issuance, NervosDAO, and state rent are genuinely complex for new users to understand.
Proof-of-work mining faces the same environmental criticism as Bitcoin.
RGB++ allows Bitcoin assets to commit to Nervos Cells, enabling smart contract operations (DeFi, NFTs, complex ownership) that settle on both Bitcoin and Nervos. This makes Nervos an execution layer for Bitcoin without modifying Bitcoin itself. As the Bitcoin ecosystem grows (ordinals, runes, BRC-20s), RGB++ provides smart contract infrastructure.
The Cell Model extends Bitcoin's UTXO concept. In Bitcoin, a UTXO tracks BTC ownership. In Nervos, a Cell can track ownership of any data with custom verification rules. Cells have capacity (in CKB), data contents, and lock/type scripts that define access and validation. This generalization enables the flexible smart contract capabilities that Bitcoin's scripting language lacks.
Holding 1 CKB gives you the right to store 1 byte of data on the Nervos blockchain permanently. This means CKB has fundamental demand tied to blockchain storage usage — if applications need to store data on-chain, they need CKB. This prevents state bloat (since storing data has a cost) and creates utility demand beyond speculation.
