Jin Network Whitepaper

Abstract

The rise of blockchains as a new Internet infrastructure has led to developers deploying tens of thousands of decentralized applications at rapidly growing rates. Unfortunately, blockchain usage is not yet ubiquitous due to frequent outages, high costs, low throughput limits, and numerous security concerns. To enable mass adoption in the web3 era, blockchain infrastructure needs to follow the path of cloud infrastructure as a trusted, scalable, cost-efficient, and continually improving platform for building widely-used applications.
We present Jin network, designed with scalability, safety, reliability, and upgradeability as key principles, to address these challenges. Jin Network has been developed over the past two years by over 200+ developers across the globe. It offers new and novel innovations in consensus, smart contract design, system security, performance, and decentralization. The combination of these technologies will provide a fundamental building block to bring web3 to the masses:1
• First, Jin network natively integrates and internally uses the Move language for fast and secure transaction execution. The Move prover, a formal verifier for smart contracts written in the Move language, provides additional safeguards for contract invariants and behavior. This focus on security allows developers to better protect their software from malicious entities.
• Second, Jin data model enables flexible key management and hybrid custodial options. This, alongside transaction transparency prior to signing and practical light client protocols, provides a safer and more trustworthy user experience.
• Third, to achieve high throughput and low latency, Jin Network leverages a pipelined and modular approach for the key stages of transaction processing. Specifically, transaction dissemination, block metadata ordering, parallel transaction execution, batch storage, and ledger certification all operate concurrently. This approach fully leverages all available physical resources, improves hardware efficiency, and enables highly parallel execution.
• Fourth, unlike other parallel execution engines that break transaction atomicity by requiring upfront knowledge of the data to be read and written, Jin Network does not put such limitations on developers. It can efficiently support atomicity with arbitrarily complex transactions, enabling higher throughput and lower latency for real-world applications and simplifying development.
• Fifth, Jin modular architecture design supports client flexibility and optimizes for frequent and instant upgrades. Moreover, to rapidly deploy new technology innovations and support new web3 use cases, Jin Network provides embedded on-chain change management protocols.
