Two new Microsoft patents reveal that the technology giant is trying to strengthen its blockchain solutions with the use of trusted execution environments (TEE), according to two documents published by the USPTO (US Patent and Trademark) Office) on August 9th. [19659002] Both applications describe how the use of TEEs could further improve the security of a consortium's blockchain network, which requires that specific nodes be supported as validation nodes (VNs) on the blockchain.
As the first Microsoft patent indicates, TEE can help to improve the security of such networks as follows:
"In an example of technology, a first node is approved during the approval of a first node. node, a predetermined type of blockchain or other security protocol code must be authorized and a predetermined list of members can be stored in a trusted execution environment (TEE) of the first node. "
According to the patent, not just a specific protocol or a membership list, but potentially a series of further agreed aspects could be stored within a TEE. The patent then outlines how to use a TEE attestation system would be able to securely verify all new participants in the system that are in possession of information corresponding to what is stored in the TEE of the first node.
According to Microsoft's filing from August 9 illustrates how a TEE can also facilitate the verification of blockchain transactions within a network of consortia. The same TEE attestation system would generate a sufficiently reliable environment in which other VNS on the network "would not need to recalculate for verification", allowing a certain pre-authorized entity to transmit "directly" the "updated official status" of a given transaction processed:
"In some examples, the entire network accepts transactions, including chaincode transactions and blockchain states are updated directly. In some examples, there is no need to copy a transaction for confirm a lockout. "
Just last week, Cointelegraph reported on the news that Microsoft's cloud computing platform based on Ethereum, Azure, had replaced its current version of Labor Consent Mechanism (PoW) with a new authority test algorithm (PoA). Microsoft has proposed that the new algorithm will improve the efficiency of creating decentralized applications (DApps) for private or consortium blockchain networks.
