Ex-Deloitte Chief to costruct “Ethereum of Supply Chain”

Eric Piscini has left the firm presently boasting 1,200 employees and beginning with just 3. Now, he has decided to choose a different road
21 May 2018   2003

Piscini was frequently approached and tempted by Deloitte’s customers to join their companies and bring his blockchain expertise on a full-time basis to their table. Finally, the in-demand blockchain executive opted U.S.-based Citizens Reserve, which is aimed to join 2 blockchains, Ethereum and JPMorgan Chase’s Quorum, in order to build a worldwide supply chain network.

Early-stage launch of Citizen Reserve suggests a common database platform and allows each level of a supply chain to be available for users. A cryptocurrency based on the ERC20 Ethereum token standard, named “Zerv,” will be issued to all users in order to access the blockchain, and to simplify seamless cross-border and internal transactions. Zerv will also be supported by real-world assets. 

The private blockchain is more for supply chain transactions, and the public blockchain is used for payments. There is a bridge that we created that is kind of our secret sauce. We don’t give away equity in the company. That’s not where the value is going to be created. The value is going to be created at the token level, not at the equity level of the company. We have decided to start with the defense industry because we have relationships with key participants in the defense industry, and it’s a very broken supply chain across the globe.

Piscini intends to restrict the involvement of speculators while keeping the token lucrative. However, it is, a struggle to detach these tokens from being termed as “securities,” as the company would invest 85 percent of the funds raised into unspecified assets. Piscini supposes that this investment will fix the price of the token and, finally, help with his original aim of dissuading speculators.

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.
