Deconstructing the Smart Redbelly Blockchain

Abstract

Typical blockchain nodes replicate the execution of requests, which include native transfers and smart contract executions. With the shift of the Web towards Web3, modern blockchains suffer from congestion which prevents them to handle user requests. Recent studies showed that modern blockchains perform poorly or lose requests to realistic Decentralized Application (DApp) workloads, impairing the shift towards Web3.In this paper, we present Smart Redbelly Blockchain (SRBB) which handles realistic DApp workloads. Smart Redbelly Blockchain improves blockchain performance with (1) Transaction Validation and Propagation Reduction, (2) caching optimizations and (3) fast block execution. SRBB outperforms Algorand, Avalanche, Diem, Ethereum, Quorum and Solana when deployed over 5 continents and under the realistic workloads of NASDAQ, Uber and FIFA using the Diablobenchmark suite. Next, we decouple SRBB that improves the peak throughput of SRBB for the NASDAQ workload by 33% and reduces its latency by 20%.
