Distributed database that is used to maintain a continuously growing list of records, called blocks.

Expase.Tech blockchain platform will be integrated wilth Gameboard, created by Power Development from Guatemala. Expanse is a "fork" of Ethereum, created by Christopher Franko, one of the earliest blockchain developer and digital currency enthuasiast. Two other co-fouder are James Clayton, creator of Cryptocurrence Collectors Club and Dan Conway, blockchain pro.

Gameboard is a platform which tracks the user's gaming actions by comparing each member or a team. It uses the reward system with points and badges. 

According to the mass media, Christopher Franko said that integration with solid app like Gameboard will help Expanse to evolve and grow by adding valuable investors and partners.

Omar Alvarez, founder of Gameboard, says that his company was searching for a reliable partner like Expanse for a long time. He describes his product as a gaming playground with reward systems, created to be used in many branches such as education, marketing and even psychology.

New unite will provide skilled teams of Gameboard and Expanse with mutual benefit. Teams can't wait to reach great results together.

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.
