Enigma Core library

Service Master Develop
CI Badge Build Status Build Status

Pure Rust Enclave && Untrusted in Rust. Core is part of the Enigma node software stack. The Core component as it's name suggests is responsible for the core operations. The core includes Remote Attestation (SGX SDK), Cryptography and execution of WASM secret contracts.

Getting Started (With the Enigma Docker)

Prerequisites

Build and Compile

  • build the enigma docker image
 cd /some/path/enigma-core/dockerfile
 docker build -t enigma_core .

The output should look like that:

Sending build context to Docker daemon  2.048kB

Successfully built cd6787969fd1
  • run docker:
docker run -v /some/path/enigma-core/:/root/enigma-core -ti -p 5552:5552 --device /dev/isgx enigma_core
  • build the project
cd enigma-core/enigma-core
make 

If the following error occurs then this is an open issue that will be solved.

error[E0463]: can't find crate for `std`
  --> /root/.cargo/git/checkouts/rust-sgx-sdk-fc8771c5c45bde9a/378a4f0/xargo/sgx_tunittest/../../sgx_tunittest/src/lib.rs:88:1
   |
88 | extern crate sgx_tstd as std;
   | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ can't find crate

error: aborting due to previous error

For more information about this error, try `rustc --explain E0463`.
error: Could not compile `sgx_tunittest`.

check out Troubleshooting and then make clean && make

Run the tests (inside Docker)

  • Build the project
make
cd app/

Run the tests (no std)

cargo test

Run the test (with std)

cargo test -- --nocapture

Run the project

cd root/enigma-core/enigma-core/bin
./app

Simulation Mode

If you want to run this in a computer that doesn't support SGX you can run both enigma-core and surface in simulation mode.
To do this, run surface with --simulation, then fire up the docker and run:

$ cd enigma-core
$ make full-clean
$ export SGX_MODE=SW
$ make # Here you can add JOBS=N to pass on to cargo the number of jobs to run simultaneously.

Troubleshooting

Errors while building with make

1. wrong sgx_tstd:
error[E0463]: can't find crate for `std`
  --> /root/.cargo/git/checkouts/rust-sgx-sdk-fc8771c5c45bde9a/378a4f0/xargo/sgx_tunittest/../../sgx_tunittest/src/lib.rs:88:1
  • Temp Solution:
rm -rf ~/.cargo/git/checkouts/rust-sgx-sdk-fc8771c5c45bde9a/378a4f0/xargo/
1. wrong wasmi:
error[E0599]: no function or associated item named `new` found for type `std::ops::RangeInclusive<_>` in the current scope
    --> /root/.cargo/registry/src/github.com-1ecc6299db9ec823/serde-1.0.76/src/de/impls.rs:2084:12
     |
2084 |         Ok(RangeInclusive::new(start, end))
     |            ^^^^^^^^^^^^^^^^^^^ function or associated item not found in `std::ops::RangeInclusive<_>`

  • Temp Solution:
rm -rf ~/.cargo/git/checkouts/rust-sgx-sdk-fc8771c5c45bde9a/378a4f0/samplecode/wasmi
