TL;DR: Wang et al. as discussed by the authors conduct a systematic study on the security threats to blockchain and survey the corresponding real attacks by examining popular blockchain systems. And they also review the security enhancement solutions for blockchain, which could be used in the development of various blockchain systems, and suggest some future directions to stir research efforts into this area.

TL;DR: A method is presented to analyze the security of quantum secret-sharing protocols against this kind of attack taking the scheme of Hillery, Buzek, and Berthiaume (HBB) as an example, and shows that the HBB protocol is insecure against dishonest participants.

TL;DR: A systematic study on the security threats to blockchain is conducted and the corresponding real attacks by examining popular blockchain systems are surveyed.

TL;DR: By a special strategy, Bob can steal Charlie's portion of information without being detected and then recover Alice's secret by himself and point out a possible way to improve the protocol to stand against this attack.

TL;DR: An efficient protocol for comparing the equal information with the help of a third party (TP) that utilizes the triplet entangled states and the simple single-particle measurement is proposed.
