The TCF was first developed at another Hyperledger Lab project – Private Data Objects (PDO) that can be found at https://github.com/hyperledger-labs/private-data-objects.

The TCF compiles TCF complies with existing and emerging standards especially,  the Off-Chain Trusted Compute Specification developed by the Enterprise Ethereum Alliance (EEA). The spec can be found at https://entethalliance.org/wp-content/uploads/2019/05/EEA_Off_Chain_Trusted_Compute_Specification_V1_0.pdf.

Direct model was introduced as a complement to the proxy model to facilitate specific use cases that are hard to address relying on the proxy model alone, e.g. processing sensor data streams (data filtering and pre-processing for IoT, supply chain), handling custom worker key update polices, and aggregating (large volume of) worker receipts.

Currently, only direct model is implemented. Proxy model for Ethereum and Fabric will be implemented next. 

It is expected that real world applications may benefit from a hybrid model that will combine elements of both proxy and direct models.
