本文提供了一种改进的拜占庭容错协议机制,即使用可验证随机函数( Verifiable Random Function, VRF )以隐秘且非交互的方式来选择一部分用户参与共识。这个协议参考了权益证明机制的思想,按照每个参与者投入的货币价值给予其相应的权重。该协议的亮点在于可扩展性,它可以支持很高的交易吞吐量并避免了工作量证明区块链在计算上付出的昂贵代价。

2019-11-05
This paper tried to shed light on the factors determining the price of Bitcoins in the short-run as well as in the long-run. The authors built an empirical model incorporating multiple economic and technological variables but also extended the existing literature by taking Twitter sentiment into account. The experimental results show that some variables have a positive effect on the price of Bitcoins, and on the contrary, some variables have negative effects. This paper helps the researchers to batter understanding the factors that influence the price of Bitcoin.
