Summary

Blockchain technology enables decentralized credible information access, leading to the evolution of economic, intellectual property protection, electronic government system, logistics, and huge amount of investment. For the further development and potential investors, there exist super chance together with super risk, because: 1) the current blockchain technology has limitations on the storage capability, low consensus efficiency, smart contract vulnerabilities, high transaction fee, and etc.; and 2) the ecosystem of the blockchain based applications is fast evolving with growing complexity, especially when it comes to the cross-chain scenario. To provide a stable and efficient running environment, IPFS and swarm are proposed to conduct efficient off-chain storage; PoRep and PosT are proposed to provide less energy-draining consensus methods; smart contract based fuzz systems are proposed to ensure the security of smart contract before deployment; and layer-2 blockchain is proposed to reduce transaction fees. However, the future trend of blockchain architecture is still an open problem. To understand the potential risk and transaction behaviors of the current dapp ecosystem, modeling based on the dapp transaction data turns out to be a hot topic.


This special issue aims at collecting the recent results from both research and industrial community on blockchain technologies.


Potential topics include but are not limited to:

• Cryptography and key management technology for blockchain

• Distributed storage system for blockchain

• Energy-efficient consensus algorithm

• Scalable consensus algorithm for consortium blockchain

    Abstract Smart contracts running on public blockchains are permissionless and decentralized, attracting both developers and malicious participants. Ethereum, the world’s largest decentralized application platform on which more than 40 million smart contracts are running, is frequently challenged by smart contract vulnerabilities. What’s worse, since the homogeneity of a wide range of smart contracts and the increase in inter-contract dependencies, a vulnerability in a certain smart contract could affect a large number of other contracts in Ethereum. However, little is known about how vulnerable contracts affect other on-chain contracts and which contracts can be affected. Thus, we first present the contract dependency… More >
