The first Beta version of the OriginTrail testnet protocol - Apollo, is to be released on June 29. All the features set for development are going to be implemented, i.e.:

  • payment mechanism;
  • consensus check with zero-knowledge privacy layer;
  • Web-of-Things standard;
  • bidding mechanism;
  • Neo4j compatibility;
  • full GS1 validation

As the usage of the OriginTrail protocol usage grows and protocol improvements are steadily implemented, the project will move towards the MainNet launch in Q3 2018. OriginTrail is the first purpose built protocol for supply chains based on blockchain. At the moment of publication, OriginTrail market characteristics are as follows:

Average price 0.138622 USD
Market cap 37,185,905 USD
Volume (24H) 248,550 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.
