Buterin to Give 3000 ETH to 3 Ethereum Startups

Twitter complaints from Prysmatic Labs, ChainSafe Systems and Sigma Prime brought a lot of money from creator of Ethereum

Prysmatic Labs, ChainSafe Systems and Sigma Prime blockchain startups received unexpected donations of 1,000 ETH each (in total about $ 300,000) from the creator of Ethereum Vitalik Buterin. Thus, he supported the developers of the updated version of the Ethereum 2.0 ecosystem, complaining about the lack of funding, CoinDesk writes.

On the problems of startups Buterin learned from the Twitter thread. In particular, the co-founder of Prysmatic Labs, Preston Van Loon, who works on the scalability of the Ethereum network, said that he was not able to pay developers a full rate.

In response to this tweet, Vitalik Buterin sent 1000 ETH.

Also, thousands of ethers were received by Sigma Prime and ChainSafe, which are engaged in developing clients for Ethereum 2.0. So, co-founder of Sigma Prime, Paul Houner, attracted Buterin’s attention with a tweet about the refusal of “several grants.”

At the same time, the head of ChainSafe only said the phrase that he "literally drop out if we got $100k in ETH."

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.
