Minichain
Minichain is a blockchain emulator that provides container-based emulation for blockchain application and network environment. You can evaluate the performance of blockchain system under different host-to-host network conditions.
Getting Started
Prerequisites
If you want to use virtual time component, it only supports ubuntu-14.04 so far.
Installing
Mininet
We modify part of Mininet's code to support virtual time. Please use following instructions to install.
$ git clone https://github.com/xwu64/mininet
$ cd mininet
$ util/install.sh
Minichain
$ cd
$ git clone https://github.com/xwu64/Minichain
$ cd Minichain
$ sudo python setup.py install
Virtual time

Running the tests
Network performance evaluation
For evaluating host-to-host delay
$ cd examples/network_evaluate
$ sudo python delay.py
For evaluating host-to-host throughput
$ cd examples/network_evaluate
$ sudo python bw.py
Application evaluation
For reproducing experiments in paper.
$ cd examples/geth_evaluate
$ sudo python block_dist.py
Trouble shooting
For error RTNETLINK answers: File exists, you need to clear existing virtual interfaces.
$ sudo mn -c
If you abnormally exit program, you should kill executing blockchain applications manually.
