Adding Concurrency to Smart Contracts [PDF]
arXiv, 2017 Modern cryptocurrency systems, such as Ethereum, permit complex financial transactions through scripts called smart contracts. These smart contracts are executed many, many times, always without real concurrency. First, all smart contracts are serially executed by miners before appending them to the blockchain.

Defining Smart Contract Defects on Ethereum [PDF]
IEEE TRANSACTIONS ON SOFTWARE ENGINEERING, 2020, 2019 Smart contracts are programs running on a blockchain. They are immutable to change, and hence can not be patched for bugs once deployed. Thus it is critical to ensure they are bug-free and well-designed before deployment. A Contract defect is an error, flaw or fault in a smart contract that causes it to produce an incorrect or unexpected result, or to ...
