Amazon and Proof-of-WorkWhile the filing contains a lot of technical jargon, the type of system described is similar to a PoW cryptocurrency, like Bitcoin (BTC) or Ethereum (ETH). The document doesn’t specifically mention blockchain or cryptocurrency, but it seems that the combination of Merkle Trees with a proof-of-work concept indicates that Amazon is working towards a solution that uses this technology. In cryptography, a Merkle Tree is a tree where each leaf node is labeled with the hash of a data block and every non-leaf node is labeled with a cryptographic hash of the labels relating to its child nodes. The use of these ‘hash trees’ allows secure and efficient verification of the content of large data structures. Merkle Trees are used in the Bitcoin and Ethereum peer-to-peer networks.
Potential Applications for AWS?Throughout the document, the usage of the system is linked to authentication and verification concepts, as well as a protective mechanism against denial-of-service (DDOS) attacks. This could find potential applications for Amazon’s AWS infrastructure. Amazon has already dipped its toes in the world of blockchain, having recently announced the Amazon Managed Blockchain (AMB). The product is designed to allow users to set up their own blockchain networks within their organizations and uses Ethereum and Hyperledger as its open source frameworks.
