Ethereum-based Sapien plans to use the Matic Network technology to create a scalable decentralized network, as well as transactions with SPN and ETH.

Ankit Bhatia, co-founder and CEO of Sapien Network, said that after a few months of development, the company will introduce a completely modernized platform with an updated remuneration distribution mechanism into which Portis wallet will be integrated. At the same time, KyberWidget will allow transactions with internal Sapien tokens (SPN) and ETH.

Bhatia also announced a collaboration with Matic Network, whose technology will be used to create a scalable decentralized social network using the Web 3 concept. According to the head of Sapien, Matic sidechains will be used to conduct transactions and send rewards for high-quality posts and comments, but Matic using the Proof-of-Stake (PoS) consensus method.

He also said that by creating a tokenized platform based on the blockchain, the developers intend to eliminate the shortcomings of conventional social networks and add those features that are absent in them, so that users can earn money on creating content. Moreover, the main goal of the platform is to ensure the confidentiality of user data and complete transparency in relations with users.

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.
