The blockchain technology is rapidly gaining grounds as a key technology, especially in the financial and supply chain management sectors. This is largely due to the ability of the technology to (i) efficiently manage the sharing of digital resources ...

The hope that cryptography and decentralization together might ensure robust user privacy was among the strongest drivers of the early success of blockchains like Bitcoin. A desire for privacy still permeates the growing blockchain user base today. ...

The cloud changed the way we manage and store data. Today, cloud storage services offer clients an infrastructure that allows them a convenient source to store, replicate, and secure data online. However, with these new capabilities also come ...

The main issue that hinders the widespread deployment of blockchains is their low throughput and high latency. This has revitalized the search for efficient Byzantine fault-tolerance (BFT) protocols. However, existing BFT protocols either require two-...

Consensus algorithm is the core of blockchain and it plays a crucial role in the performance of the blockchain. In general, there are two types of blockchain consensus algorithms: the Bitcoin-like Nakamoto consensus (NC) algorithms and the Byzantine ...

Flash Loan, as an emerging service in the decentralized finance ecosystem, allows users to request a non-collateral loan. While providing convenience, it also enables attackers to launch malicious operations with a large amount of asset that they do not ...

Proof-of-work (PoW), the most prevalent consensus layer for permissionless blockchains, requires miners to devote a huge amount of computational resources. As a consequence, some miners use application-specific integrated circuits (ASICs) for PoW, which ...
