The repository contains C++ implementation of OHIE. The technical aspects of the approach are described in our paper.
The code here is tested in Ubuntu 20.04 with Boost version 1.67 and Openssl version 1.1.1f. Take care when install these libararies.
Makefile has been changed a lot, a seperated complier and link is nessary or to get multi-define error which hard to deal with. A clean and delete target is made for better use.
quicktest.sh is not recommanded, a restart of it can't kill the one is running and leaves a lot of processing in ps list.
The Following is the origin README, That's all and Good Luck.
The code has been tested on Ubuntu 16.04 with Boost ASIO library installed:
sudo apt-get install libboost-all-dev
- Compile the code
make - Run the script
quick_test.sh
This will run OHIE network of 3 nodes -- their outputs are written in outputnodeX.txt. So, while running, for example, check the output with tail -f outputnode1.txt.
At the end, make sure to kill the network, i.e. fuser -k *.
There are many parameters that can be configured, starting form the IP address of the nodes, to number of chains, block sizes, mining times, etc:
- For most widely used parameters, check the file
_configuration. - For a full list of parameters, check
configuration.cpp. - The list of network nodes (ip:port) is defined in a separate file, check
_peers - To start a single node use
./Node <portNumber> <file_peers>
Large scale experiments (based on the above code) were conducted on Amazon EC2, using the scripts from amazonEC2 folder.
Note: For each AWS region you want to use, make sure you have the public key written in a file and stored in keys folder, and have the correct launching templates. Update regions.py to reflect the file paths and the templates.
