AMAZON RECEIVED A PATENT TO CREATE A CRYPTOGRAPHIC SYSTEM BY POW CONSENSUS

The technology giant Amazon has received a patent for various methods of creating a cryptographic system based on the PoW consensus.

The patent application was filed back in 2016, and the patent itself was issued this week by the US patent and trademark Office (USPTO). The paper describes how Merkle trees, among other things, can be used as a solution to problems of the proof of work (PoW) method.

The structure of Merkle trees allows you to check data transmitted between computers and in P2P networks such as blockchains. It is used to ensure that the blocks are not tampered with. PoW is a consensus-building method that is used to secure networks by asking a network member to do work that often involves using the computing power of a computer to solve complex mathematical problems.

The patent also mentions “cryptographic key”, “digital signature” and “public signature key”, among other concepts related to blockchain and cryptocurrencies.
