The founder of Ethereum, Vitalik Buterin, asked the community to prompt him to quit his work on the crypto platform for the position at Google. This is reported by Cryptovest.

Buterin posted a poll on this issue in his Twitter along with a screenshot of the letter, in which he was offered to join the search giant. Later the tweet was deleted, probably due to the fact that Buterin accidentally opened the email address of the sender (in the original message, the address was completely visible).

The letter was sent by Elizabeth Garcia, a HR specialist at Google, as described in her profile on LinkedIn.

In mid-March, it became known that Google is developing its own solution for the cloud services and a distributed ledger that third parties can use to send and verify transactions.

In April, the founders of the Nebulas, Loopring and Gifto crypto currency projects and former Google employees Hitters Syu, Daniel Wang and Andy Tian created a community called xGoogler Blockchain Alliance (GBA) for other ex-Gougs interested in blocking technology.

The representative of Google also confirmed the information that the company is engaged in its own developments in the field of distributed registry technology, but refused to disclose details.

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.
