Abstract—The development of underlying technologies in blockchain mostly revolves around a difficult problem: how to enhance the performance of the system and reduce various costs of nodes (such as communication, storage and verification) without compromising the system’s security and decentralization. Various layer-1 and layer-2 protocols have provided excellent solutions for this challenge. However, they cannot yet be considered as a “silver bullet”. This paper proposes EZchain—a novel decentralized “scale-out” ledger system designed for web3.0, aiming to enable blockchain technology to truly support ledger applications in large-scale fully decentralized networks. Without compromising security and decentralization, EZchain successfully accomplishes the following milestones: 1) Scalability: The theoretical throughput of EZchain can be infinitely expanded, nearly unaffected by bandwidth and other resource constraints. 2) Consumer-Grade Hardware Compatibility: EZchain is designed to be compatible with consumer-grade hardware, supporting storage, computation, and verification requirements. 3) Efficient Transaction Confirmation: EZchain strives to maintain transaction confirmation delays within one minute. Our prototype experiment demonstrates that under typical daily bandwidth network conditions, EZchain’s performance in all aspects approaches that of the accounts in centralized payment systems. This provides a solid infrastructure for realizing mobile payments in web3.0.

I. Introduktion

I blockchain-applikationer har opnåelse af den samme centrale server-niveau ydeevne af web2.0 uden at ofre decentralisering og sikkerhed altid været en vigtig flaskehalse, også kendt som blockchain umulige trekant.

Med hensyn til ovennævnte udfordringer introducerer vi i dette papir EZchain, en blockchain-løsning, der er karakteriseret ved sin høje ydeevne, decentralisering og robuste sikkerhed. I modsætning til pseudo-decentralisering, lag-2 og off-chain-koncepter overholder EZchain strengt decentraliseringsprincipperne og opnår lag-1 ydeevne gennembrud.

EZchain implementerer en banebrydende konsensusalgoritme designet til at minimere konsensus, transmission og lagring af information. Den introducerer en ny datastruktur, "værdi", der adskiller sig fra UTXO-modellen i Bitcoin [1] eller kontobalancemodellen. Denne unikke kombination af datastruktur og algoritme repræsenterer efter vores viden en hidtil uset tilgang inden for blockchain skalerbarhed. Den underliggende begrundelse for EZchain's bemærkelsesværdige ydeevne ligger i den relative stabilitet af "værdi" -mængden, i modsætning til et stadigt stigende transaktionsvolumen. Dette skift i fokus på værdioverførsel tilbyder unikke fordele og optimeringsstrategier over traditionelle metoder. For empirisk at vurdere EZchain's effektivitet udviklede vi et prot
