Intel to Patent 'No Miners' Blockchain

System will use real computers with a predefined set of parameters that will determine how the validation of new blocks will be performed

Intel intends to patent a new way of verifying transactions in a distributed ledger, CoinDesk reports.

In an application published by the US Patent and Trademark Office, the company describes a method that can be used to split and automatically update distributed registries, where the operator can independently verify the correctness of new blocks and the admissibility of adding them to the register.

Thus, the solution proposed by Intel differs from the traditional blockchain used by bitcoin, etc., represented by networks of competing nodes that verify and record transactions for awards.

In its application, Intel writes that some systems based on distributed registries can be represented by blockchains, but at the same time makes a distinction between the two technologies.

According to the document, the system will use real computers with a predefined set of parameters that will determine how the validation of new blocks will be performed.

Distributed ledgers have inherent scalability issues. When all of the validators in a DLS must have a copy of all transactions, all of the transactions must be broadcast to all of the validators. These broadcasted transactions create a very large number of network messages.

Mentioning the scalability problems with which blockchains have to face today, the authors write that a distributed registry may not be the most efficient mechanism for storing data.

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.
