Recently, Sirin Labs has shared an image of the front glass for FINNEY blockchain smartphone. Now, the project is preparing to reveal the whole design of the phone on June 12. In the long run FINNEY smart devices will create a blockchain network of their own using a distributed ledger consensus mechanism.

Fast payments between the peers will be fee-less, and each device will feature a cold storage crypto wallet that is compatible with the most common cryptocurrencies. The platform will provide a UI/UX friendly for making secure payments.

FINNEY look in profile

The phone will feature a quick-charge function (50% within 30 minutes) and a secure P2P battery trading within SIRIN OS (strangers can ask to charge their phone in exchange for a reward of SRN tokens). At the moment of publication, Sirin Labs market characteristics are as follows:

Average price 0.313037 USD
Market cap 71,766,246 USD
Volume (24H) 7,172,880 USD

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   1018

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.
