Abstract

A full blockchain node for preserving privacy of a lightweight blockchain client in a blockchain network includes at least one computer device having an operating system. A trusted execution environment is installed on the at least one computer device such that code is executable by the trusted execution environment in isolation from the operating system. The trusted execution environment is configured to communicate with the lightweight blockchain client for performing blockchain transactions in a blockchain network.
