This folder contains a PoC of the Ephemeral Mining Relay described in the paper. The gas measurements can be performed by running the unit tests.
The code uses the SafeMath library
from openzeppelin
and parts of a utils library for manipulating bytes with solidity.
To setup the environment use the shell script docker_build_smartcode.sh to create two docker containers.
$ bash docker_build_smartcode.shAll tests are carried out on a ganache test chain. We use the official latest ganache docker image which is pulled by the setup script automatically.
The development environment used web3py which is installed in the smartcode docker image during the build process.
The docker file for setting up the image is smartcode.python.p2w.Dockerfile.
All python requirements automatically installed in the container are defined int smartcode.python.p2w.requirements.txt
First start the two containers in two different shells and keep them running.
$ bash docker_run_ganache.shYou see the output of ganache spawning a deterministic testnet setup with a series of accounts initialized with ether.
$ bash docker_run_smartcode.shYou see the smartcode environment which also launches jupyter for convenient interactive testing.
Now you can login to the smartcode container and run all test cases using pytest using the make file.
You can also provide the current gas price (in Gwei), as well as the current exchange rate (1 ETH in USD).
See the example below:
$ bash docker_exec_smartcode.sh
$ GWEI=27000000000 EXR=389.20 make all
