Meepo implementation on OpenEthereum.

MEEPO = Multiple Execution Environment Per Organization. (It is also a Dota hero who can split himself, each one acting independently but relying on together, just like the shards.)

This is an implmentation based on the paper: P. Zheng, Q. Xu, Z. Zheng, Z. Zhou, Y. Yan and H. Zhang, "Meepo: Sharded Consortium Blockchain," 2021 IEEE 37th International Conference on Data Engineering (ICDE), 2021, pp. 1847-1852, doi: 10.1109/ICDE51399.2021.00165.

Since Meepo-Geth (Golang) is unable to be open-source thanks to the copyright, our community provides another implementation (Rust) based on the published paper.

1. Install Rust v1.51

$ curl https://sh.rustup.rs -sSf | sh
$ rustup override set 1.51

2. Build Meepo-OpenEthereum

$ git clone http://github.com/InPlusLab/Meepo/
$ cd Meepo/build/
$ ./debug.sh # or ./release.sh

3. Run Node0 (Shard0)

$ cd Meepo/build/
$ ./initrun0.sh

4. Run Node1 (Shard1)

$ cd Meepo/build/
$ ./initrun1.sh

5. Try anything you want just use Web3.js or other Ethereum toolchain. As for benchmark, please see the following.

(32x4=128 machines in maximum, each machine is equipped with 4 vCPU, 32 GiB memory, and 894 GiB NVME disk, 102400 accounts per shard, 100000000+ transactions to an ERC20-like contract.)
