Blythe Masters, one of the most well-known and respected figures in the world of corporate blockchain solutions, has left the post of CEO of New York-based Digital Asset Holdings, which she has occupied for the past three years.

The company’s statement says that Masters remains a shareholder, strategic advisors and a member of the board of directors of Digital Asset Holdings. As CEO, she leaves due to personal circumstances.

Acting CEO appointed AG Gangadhar, in the past held senior positions in Google, Microsoft, Amazon, Cruise (GM) and Uber, and since April this year, headed the board of directors of Digital Asset Holdings.

Blythe Masters led the company in 2015, a year after its creation. Under her leadership, Digital Asset has become one of the leading companies developing blockchain solutions for the corporate sector.

The company attracted multimillion investments, closing the last round of financing in the amount of more than $ 40 million in October 2017. Its partners include Depository Trust and Clearing Corporation, Google Cloud and the Australian Stock Exchange.

Digital Asset also launched a blockchain platform that allows traders to carry out operations in the financial market without the need to disclose confidential information.

Potentional Vulnerabilities Found in ETH 2.0

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

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.
