GoByte is going to release its wallet update to v0.12.2.3 on June 8. This way, the project prepares for the overall blockchain update coming later. The update will introduce features like governance (gets activated at block 158,560), superblock (gets activated at block 162,592) and increase of Masternode rewards. The new wallet will be available for Windows, OS X and Linux systems.

Fixed behaviours concern InstantSend (coin selection in some edge cases is corrected), '-liquidityprovider' mixing mode, 10x fee reduction. An experimental HD wallet is included into the update. Also changes were made to Consensus Protocol and 100kB transaction limit. Additional details can be found here. At the moment of publication, GoByte market characteristics are as follows:

Average price 3.47 USD

Potentional Vulnerabilities Found in ETH 2.0

Least Authority have found potentional security issues in the network P2P interaction and block proposal system
26 March 2020   964

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.
