 3 | # SGX-Runtime
 4 | 
 5 | Based on [Integritee Node Template](https://github.com/integritee-network/integritee-node)
 6 | 
 7 | This substrate runtime is instantiated inside a Intel SGX enclave in the [Integritee framework](https://book.integritee.network/). Probably all substrate compatible pallets can be integrated and executed confidentially.
 8 | 
 9 | This repo also hosts our SGX patches for `sp-io` and `externalities`.
10 | 
11 | # test build
12 | 
13 | This crate is meant to be used in SGX environment and may not build on its own.
14 | Therefore, this repo contains a test crate setting up SGX tstd. Build it with:
15 | 
16 | ``` 
17 | cd test_no_std
18 | export SGX_SDK=/opt/intel/sgxsdk
19 | make
20 | ```
21 | If it builds without `std` collisions, you're good. Linker errors can be safely ignored.
