Mizuho to invest in Ethereum Startup Omise

Neutrino, the country’s first blockchain space of Ethereum-based startup Omise Japan, will be sponsored by one of Japan’s three so-called ‘megabanks’ Mizuho

The country’s first specialized blockchain co-working space Neutrino was instituted  by Omise in Tokyo in March of 2018. Omise, a Thai-based launch, sees Ethereum co-founder Vitalik Buterin among its advisors and closed a $25 million ICO in new financing last year to construct a decentralized payments platform Omise Go, powered by OMG, an ERC20 token cryptocurrency. The project aims to advance study to ultimately deploy operational implementations of blockchain tech and cryptocurrency in services and businesses.

One of the largest Japanese banks Mizuho declared on Friday that it will sponsor the coworking space in an arrangement that will also see the bank turn a “long-term tenant” of the coworking space.

Mizuho considers that blockchain is a decentralized technology that will have a transformative impact across industries, beginning it will “simplify and optimize” business operations of different types. In outlining its own aims to implement the technology to deliver better financial services to its customers, Mizuho guesses Neutrino and the interactions within the coworking space “will bring us one step closer to developing commercial applications for blockchain technology.”

In addition to sponsoring Neutrino, Mizuho will be a long–term tenant of the coworking space, and we look forward to finding applications for blockchain technology and being able to develop new business areas together with the wide variety of sponsors, members, and other specialists Neutrino plans to attract.

Mizuho has experimented and deployed a number of blockchain applications in record keeping, cross-border securities transactions, trade finance with tech partner IBM and document sharing.

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   202

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.
