Blockumulus: A Scalable Framework for Smart Contracts on the Cloud
Nikolay Ivanov, Qiben Yan, Qingyang Wang

TL;DR
Blockumulus introduces a scalable framework that leverages centralized cloud infrastructure and overlay consensus to support decentralized smart contracts with high throughput, low latency, and unlimited storage, overcoming traditional blockchain limitations.
Contribution
It presents a novel approach to blockchain scalability by centralizing network support and deploying decentralized smart contracts on cloud infrastructure using overlay consensus.
Findings
Supports 20,000 transactions in under 26 seconds
Achieves transaction latency of 2-5 seconds under normal load
Provides scalable computation, storage, and throughput
Abstract
Public blockchains have spurred the growing popularity of decentralized transactions and smart contracts, but they exhibit limitations on the transaction throughput, storage, and computation. To avoid transaction gridlock, public blockchains impose large fees and per-block resource limits, making it difficult to accommodate the ever-growing transaction demand. Previous research endeavors to improve the scalability of blockchain through various technologies, such as side-chaining, sharding, secured off-chain computation, communication network optimizations, and efficient consensus protocols. However, these approaches have not attained a widespread adoption due to their inability in delivering a cloud-like performance, in terms of the scalability in transaction throughput, storage, and compute capacity. In this work, we determine that the major obstacle to public blockchain scalability is…
