CasperLabs to Conduct Tokensale

The exchange validation offer will be conducted at the BitMax with a goal to raise $3M

Startup CasperLabs entered into a partnership with the BitMax exchange to conduct a tokensail in the format of an exchange validation offer (EVO) on March 30. In total, it is planned to attract up to $ 3 million. CoinDesk writes about this.

In 2019, CasperLabs raised $ 14.5 million from Arrington XRP Capital and other investors. Project consultants include Ethereum Foundation researcher Vlad Zamfir.

Initially, the startup was engaged in experiments with the protocol developed by Zamfir for scaling Casper, but subsequently switched to developing its own blockchain. The launch of its main network should take place before the end of the year. Arrington XRP Capital founder Michael Arrington said he was not sure whether his company would want to participate in the token sale before launching the main network. At the same time, he confirmed that, “most likely,” he would become the operator of one of the nodes.

CLX tokens purchased on BitMax will automatically be credited to the accounts for staking after the opening of the main network. To do this, BitMax will also launch its own node. Within 90 days from now, investors will be prohibited from selling tokens.

In addition, the startup is negotiating with some other trading platforms and companies offering their customers a staking service. So far, few have expressed a desire to become node operators, which could damage CasperLabs plan to provide an increased level of decentralization already at the start.

The CasperLabs team has an 8% CLX emission, which will be limited to a three-year vesting period. It is expected that the total capitalization of the project will be about $ 100 million, CoinDesk writes.

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.
