Amazon has patented a cryptographic system based on the Proof-of-Work

Technology giant Amazon became interested in cryptocurrency technology research. This is evidenced by the patent received by the company, which, among other things, mentions the consensus algorithm Proof-of-Work and the Merkle Tree data structure, reports CoinDesk .

The patent application was filed back in December 2016, and it describes the PoW-based system, which provides access to the resource for the computational work performed.

“The first party (for example, a client computer system) can request access to a computing resource. The second party (for example, the service provider) can determine the call that can be made to the first party. The actual solution to the problem can be generated and provided for the execution of the request, ”the patent text says.

The Merkle tree at the same time allows you to check the data transmitted in peer-to-peer networks, confirming the accuracy of the found blocks.

The application description also states that this solution can be used to prevent DoS and DDoS attacks:

“The algorithm will force the DoS or DDoS attack participants to generate the correct work validation solution, which may require the use of computing resources in attacking systems and significantly reduce the speed with which organizations participating in the attack can send requests,” the document says.

It is worth noting that despite the use of the terms “cryptographic key”, “digital signature”, “public key signature” and the SHA-256 hashing algorithm, the blockchain or cryptocurrency is not mentioned directly in the patent.

Where exactly the patented system will be used is not yet known – there have been no official comments from the company.

Recall that in November 2018, Amazon launched a blockchain platform for developing decentralized networks.
