TL;DR: In this paper, a contract verification method for off-chain private calculation nodes is proposed, which comprises the steps of obtaining a remote certification report of an offchain trusted execution environment created for an off-Chain private calculation node, determining that the off-chains trusted execution environments is trusted according to the remote attestation report; to-be-verified contract information of a target under-chain contract deployed at the node is acquired, the to be verified contract information is signed by the node, and the identity private key is maintained by a node in the under-Chain trusted execution node

- 01 May 2020
TL;DR: In this paper, a trusted execution environment is established in the private computing node under the chain by sending an off-chain contract calling request sent by a blockchain node; and executing the under-chain contracts in the trusted environment, initiating access to the remote server through the oracle machine under the condition that the underchain contract has an external data access demand.

Registration and authorization method, apparatus and system
TL;DR: In this paper, the authors propose a registration and authorization system for block chains, where the authorization server is a node in a block chain network and stores a plurality of blocks, each block storing authorization information, including identification information for identifying a user; allocating authorization information to the user, the authorization information for indicating service accessed by the user; writing the identification information and the authorization status into the blocks of the block chain via the authorization servers.
