SGX enclave configuration with zero knowledge proofs for financial products

X-Margin is a distributed clearing solution that helps facilitate clearing of trades between parties without the need for a central counterparty. X-Margin particularly focuses on derivatives, verifying
margin usage of clients at venues, and ensuring collateral held is sufficient.

The X-Margin system consists of multiple components built on top of different technology stacks.

In-house trade booking venue with a Java + MongoDb backend and a React frontend
A Kx/kdb+ system that captures and processes time-series data for a number of analytics that integrate with a number of external venues and service providers
A privacy preserving computation layer implemented on top of SGX
