Two new patents from Microsoft reveal that the tech giant is looking to bolster its blockchain solutions with the use of trusted execution environments (TEEs), according to two filings published by the U.S. Patent and Trademark Office (USPTO) August 9.

Both applications outline how the use of TEEs could further improve security within a consortium blockchain network, which requires that specific nodes are endorsed to act as validator nodes (VNs) on the blockchain. As Microsoft’s first patent filing indicates, TEEs can help to improve the security of such networks in the following way: “In one example of the technology, a first node is endorsed. During endorsement of a first node, a pre-determined type of blockchain or other security protocol code to be authorized and a pre-determined membership list may be stored in a trusted execution environment (TEE) of the first node.” According to the patent, not only a specified protocol or membership list,
