Nervos Network: Universal Passport to Blockchain

The Nervos Network is a collection of protocols and public blockchain ecosystem aiming to solve the biggest challenges facing blockchains like Bitcoin and Ethereum today.

The Nervos CKB (Common Knowledge Base) is the layer 1, proof of work public blockchain protocol of the Nervos Network. It allows any crypto-asset to be stored with the security, immutability and permissionless nature of Bitcoin while enabling smart contracts, layer 2 scaling and captures the total network value through its "store of value" crypto-economic design and native token, the CKByte.

The native token on the CKB blockchain is CKB, and the on-chain storage unit is Cell. The Cell model is a universal UTXO model that supports user-defined tokens and smart contracts. Storing data, state, and other consensus results on the Nervos CKB blockchain consumes cells. 1 CKB = 1 Byte.

Like BTC's halving cycle, CKB's base issue halving cycle is halved every four years. CKB mainnet Lina went live on November 16, 2019. Nervos successfully upgraded its mainnet from Lina to Mirana on May 10, 2022.

Godwoken: EVM compatible layer 2 built on Nervos Layer 1

Godwoken is an optimistic rollup ultimately inheriting security from layer 1. Godwoken provides instant transaction finality with low fees and a completely Ethereum compatible environment on Nervos

Why choose Godwoken?

Godwoken is secured by Nervos Layer1 with high throughput and security at Layer2 through Optimistic Rollup. Thanks to Ethereum EVM support, developers can deploy Ethereum smart contracts at Godwoken, while maintaining transaction scalability, fast confirmation, and low cost.

THE CREATION OF UNIVERSAL APPS

Nervos has built a suite of tools which we have called the Universal Passport. This is our solution to creating a next generation of interoperability that will empower the creation of Universal Applications — Apps that transcend individual blockchains to work seamlessly across every chain in the ecosystem.

In this tool box, we have PW Core, the Force Bridge and Polyjuice.

PW Core: Allowing users to enter the Nervos Network through various portals

Users do not need to download new software or generate new keys/addresses to access Nervos, they can use their existing Ethereum addresses and wallets to receive and send CKB directly. 

Force Bridge: Decentralized cross-chain functionality that feels centralized

Force Bridge is a cross-chain interoperability bridge that allows assets like tokens and NFTs to move between Nervos and other connected blockchain ecosystems.

Polyjuice: a 100% EVM-compatible Ethereum on CKB Solution

Polyjuice is a layer 2 solution that provides Ethereum Virtual Machine (EVM) compatibility for smart contracts running on Nervos.This means that Polyjuice gives developers the ability to port their existing Ethereum dApps to CKB with minimal effort. The goal of Polyjuice is to be 100% compatible with all EVM smart contracts, libraries, and tooling.
