Litentry Weekly Updates (June 7–13)

✨ SubstraTEE for storing linked identity information privately

  • The relationship of users’ different IDs is stored in a TEE environment. Requests sent to the TEE will be encrypted by a shielding key so that no node in the network can decrypt the information.
  • Any computation work that happens inside SubstraTEE worker enclaves can’t be observed by the network nor by the operator of the worker service.
  • TEEs allow us to execute any state update without sharing our data with the blockchain validator or other users. The blockchain serves as a root of trust and all the data remains inside the protected enclaves off-chain.
