This project aims at providing the scripts, logs, and analytic results for Meepo Blockchain (the Rust implementaion on OpenEthereum).

In short, it provides open-source and reproducible benchmark results for Meepo-OpenEthereum.


We use 128 AliCloud servers as a test bed. Each machine is equipped with 4 vCPU, 32 GiB memory, and 894 GiB NVME disk. The detailed configuration of the ECS (ecs.i2.xlarge) can be found here.


The scripts are in encoder/ and client/.
First, we encode and sign the transactions for benchmark.
Second, for each shard, we use a client to submit the transaction to blockchain one by one.
All transactions are signed and sent in the way as the same as Ethereum, using Web3.js.


All the logs are in the meepo128/ directory in this repo.
With the following commands, you can verify the results afterwards.

$ git clone
$ cd MeepoBenchmark/meepo128
$ ls *.zip | xargs -n1 unzip # you should install unzip first or mannualy unzip
$ cd .. 
$ python3 # or other Python script
