Crypto May Be Another "Time Store", Shiller Believes

Nobel laureate in economics believes that cryptocurrency is another attempt to change the format of money

Nobel laureate in economics Robert Shiller said that cryptocurrencies are not the first attempt to change the existing format of money, and that all previous attempts ended in complete failure. This is reported by Bloomberg.

So, he gave an example of the so-called "time store", which was created by anarchist Josiah Warren in 1827 in Cincinnati. In this retail store, products were sold for hours of work or "labor bills."

Two years later, in London, textile industrialist Robert Owen attempted to found the Labor Exchange on the basis of labor tickets.

The concept of the "electric dollar," stressed Shiller, completely failed and was rather a comedy, not an innovation.

No one, outside of computer science departments, can explain how cryptocurrencies work. That mystery creates an aura of exclusivity, gives the new money glamour, and fills devotees with revolutionary zeal. None of this is new, and, as with past monetary innovations, a compelling story may not be enough.

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.
