That`s the second time McAfee has run for president, with his previous campaign in 2016 also being supported by the Libertarian party. “In spite of past refusals, I have decided to again run for POTUS in 2020,” he claimed on Twitter.

If asked again by the Libertarian party, I will run with them. If not, I will create my own party. I believe this will best serve the crypto community by providing the ultimate campaign platform for us.

As the founder of McAfee antivirus software, John McAfee has always been involved  in cybersecurity, a main feature of cryptocurrencies and blockchain. Being also a long time libertarian, McAfee has advocated for the right to privacy and minimal government interposal to citizens’ affairs. McAfee is actively engaged in the cryptocurrency sphere, leveraging his reputation as a cyber security expert to become a cryptocurrency influencer.

With a Twitter following of almost a million people, McAfee regularly promotes altcoins that he finds interesting. He’s not one to hold back on controversial points of view, lately sharing how he strongly believes ‘powerful forces’ are trying to derail the progress of the cryptocurrency revolution, declaring there is a “war” going on between cryptocurrencies and the powers that be. 

However, despite McAfee shares a lot of classy content about the value of decentralized money transforming society, he would most likely keep confined to the libertarian party. 

The cryptoindustry is slowly entering the mainstream, some may argue that it should have a less controversial character representing it. Currently the winning strategy of the cryptosphere is closely connected with education and positive public perception. 

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   1018

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.
