ERGO has updated its status on the Testnet 2.0. The development is as planned: the release is scheduled for June 1. Serialization and specifications of spending proofs, coins and transactions are under finalization.

The testnet will feature:

  • Schnorr protocol and proof of Diffie-Hellman tuple knowledge protocol as building blocks
  • Arbitrarily complex AND and OR conjectures (to build complex multisig schemes)
  • SecP384R1 curve
  • A lot of (typed) predicates over blockchain state.
  • No implicit rules to produce money out of thin air. No coinbase transactions, no implicit fee. All the coins rewarding miners will be created before the genesis block and locked up to certain heights.

ERGO is a decentralized and open-source cryptocurrency based on novel scientific ideas with a user-friendly protocol that is executable on a smartphone. At the moment of publication, ERGO market characteristics are as follows:

Average price 4.36 USD
Market cap 1,733,611 USD
Volume (24H) 78,660 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.
