Bitcoin Plus (XBC), an alternative cryptocurrency that uses the Tor Network for IP address privacy and also uses Hybrid Proof of Stake and Proof of Work, is developing in a positive direction showing a significant price rise, increasing by 85% within past 24 hours and growing from less than $60 on November 12 to $124 on November 13.

Bitcoin Plus was launched in 2014 on Poloniex and since that time has remained nearly flat for most of its life cycle having a price of around $40. Nevertheless during last 7 days it grew up by 262% and at the press-time has market capitalisation of more than $12 million.

Such a notable rise of the alternative cryptocurrency might be linked to the recent fluctuations of its siblings Bitcoin and Bitcoin Cash due to the announcement of SegWit2x developers about fork cancellation.

Potentional Vulnerabilities Found in ETH 2.0

Least Authority have found potentional security issues in the network P2P interaction and block proposal system
26 March 2020   979

Technology security firm Least Authority, at the request of the Ethereum Foundation, conducted an audit of the Ethereum 2.0 specifications and identified several potential vulnerabilities at once.

Least Authority said that developers need to solve problems with vulnerabilities in the network layer of peer-to-peer (P2P) interaction, as well as in the block proposal system. At the same time, the auditor noted that the specifications are "very well thought out and competent."

However, at the moment there is no large ecosystem based on PoS and using sharding in the world, so it is impossible to accurately assess the prospects for system stability.
Also, information security experts emphasized that the specifications did not pay enough attention to the description of the P2P network level and the system of records about Ethereum nodes. Vulnerability risks are also observed in the block proposal system and the messaging system between nodes.

Experts said that in the blockchains running on PoS, the choice of a new block is simple and no one can predict who will get the new block. In PoS systems, it is the block proposal system that decides whose block will fall into the blockchain, and this leads to the risk of data leakage. To solve the problem, auditors suggested using the mechanism of "Single Secret Leader Election" (SSLE).

As for the peer-to-peer exchange system, there is a danger of spam. There is no centralized node in the system that would evaluate the actions of other nodes, so a “malicious" node can spam the entire network with various messages without any special punishment. The solution to this problem may be to use special protocols for exchanging messages between nodes.
