VM Matters: A Comparison of WASM VMs and EVMs in the Performance of Blockchain Smart Contracts [article]

Shuyu Zheng, Haoyu Wang, Lei Wu, Gang Huang, Xuanzhe Liu
2021 arXiv   pre-print
This paper conducts the first measurement study, to measure the performance on WASM VM and EVM for executing smart contracts on blockchain.  ...  To our surprise, the current WASM VM does not perform in expected performance. The overhead introduced by WASM is really non-trivial.  ...  Then we present the experimental results of the performance measurement, including a comparison between EVM engines, a comparison between WASM engines, and a comparison between WASM engines and EVM engines  ...

of the IoT, using the smart home as the reference domain.  ...  If the underlying consensus protocols performance and fault tolerance is also considered, then only a small number of platforms meet the requirements of our reference IoT domain.  ...  They created a simple smart contract on the Ethereum platform, wrote the high-level and the EVM-level specifications, and then verified this smart contract.  ...

Analysis of Blockchain Based Smart Contracts

Naveed Ahsan
2020
Performance issue is related to the number of smart contracts executing at a given time in Blockchain.  ...  EOS uses Web assembly to code smart contracts. WASM web assembly will let coders develop smart contracts in their own language of choosing and compile bytecode onto supported browser.  ...

Scalable and privacy-preserving off-chain computations

Jacob Eberhardt, Technische Universität Berlin, Stefan Tai
2021
Off-chaining reduces the work a blockchain has to perform and improves its privacy properties by avoiding publishing data in the first place.  ...  As a second contribution, we provide an in-depth analysis and comparison of off-chain computation approaches, which represent a particularly powerful privacy- and scalability-engineering abstraction.  ...  Acknowledgements This thesis could not have been completed without the support of many brilliant minds who inspired, influenced, and supported me over the last years.  ...
