TLDR
This work analyses the security vulnerabilities of Ethereum smart contracts, providing a taxonomy of common programming pitfalls which may lead to vulnerabilities, and shows a series of attacks which exploit these vulnerabilities, allowing an adversary to steal money or cause other damage.Abstract:
Smart contracts are computer programs that can be correctly executed by a network of mutually distrusting nodes, without the need of an external trusted authority. Since smart contracts handle and transfer assets of considerable value, besides their correct execution it is also crucial that their implementation is secure against attacks which aim at stealing or tampering the assets. We study this problem in Ethereum, the most well-known and used framework for smart contracts so far. We analyse the security vulnerabilities of Ethereum smart contracts, providing a taxonomy of common programming pitfalls which may lead to vulnerabilities. We show a series of attacks which exploit these vulnerabilities, allowing an adversary to steal money or cause other damage.read more

An Improved Method for Data Storage Based on Blockchain Smart Contract
Dongxiang Song,Mingju Yuan +1 more
TL;DR: In this article, an improved method for storage of smart contract data based on blockchain to optimize the data upload format of off-chain systems was proposed. But the experimental results show that the improved system implements the function of adding, deleting, and modifying data on the chain.

Research on key technologies and development of blockchain
Abstract: Blockchain is considered as a revolutionary technology that has recently fueled extensive attention across many industries. Except for Bitcoin, it has been applied into diverse areas ranging from finance, logistics to food traceability and medical care. It will not take long for blockchain to change the whole society. Although there have been a large number of papers concentrating on blockchain application in a variety of areas, there is lack of a comprehensive survey about blockchain from the perspective of technology and application. To this end, we present a comprehensive overview on the core technologies in blockchain, including cryptography, smart contract and consensus mechanism. In addition, this paper reviews blockchain application and discusses existing problems and bottlenecks in the development of blockchain technology.

Dynamic Vulnerability Detection on Smart Contracts Using Machine Learning
TL;DR: In this paper, a monitoring framework is proposed to detect reentrancy vulnerabilities in Ethereum smart contracts, which relies only on transaction metadata and balance data from the blockchain system; their approach requires no domain knowledge, code instrumentation, or special execution environment.

Ethereum: A Secure Decentralised Generalised Transaction Ledger
TL;DR: Ethereum as mentioned in this paper is a transactional singleton machine with shared state, which can be seen as a simple application on a decentralised, but singleton, compute resource, and it provides a plurality of resources, each with a distinct state and operating code but able to interact through a message-passing framework with others.
