Havven is releasing its stablecoin nUSD on June 11. The release marks the launch of the Havven network. nUSD is claimed to provide a mechanism to mitigate the price volatility in the blockchain ecosystem. The network itself is notable as it uses a peculiar stability mechanism that rewards havven-holders for providing stability to nomin users.

Havven is collaborating with intimate.io, Swapy and Deconet to make use of nUSD on the aforementioned platforms. First nomin iteration - eUSD, can still converted into ETH (vice versa option is deactivated prior to nUSD release). eStore, an eCommerce platform with nomins support is closed to public until the release of nUSD.

Havven is a decentralized payment network where transactions fees are collected from users of the network. At the moment of publication, the Havven market parameters are as follows:

Average price 0.575490 USD
Market cap 35,073,679 USD
Volume (24H) 1,493,690 USD

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.
