| Features | Descriptions |
|---|---|
| Sharding | 4 shards, transactions within the same shard and between different shards are supported higher transaction fee for cross-shard transaction |
| Smart Contracts | smart contracts are supported within the same shard |
| Scdo Wallet | easy-to-use wallet |
| High TPS | same shard TPS: 500/shard, cross shard TPS: 12/shard |
| Auditable Supply | total supply: 1,000,000,000 SEELEs, 300,000,000 SEELEs for mining |
| Consensus Algorithm | MPOW: matrix-proof of work algorithm |
| Mining Reward | 3150000 blocks/era and era reward follows [6, 4, 3, 2.5, 2, 2, 1.5, 1.5] order until reaches the last reward of 1.5 SEELEs |
| Transaction Fee | self-customized transaction fee, higher fee for cross-shard transaction |
| Block | 100 KB block size, 10 seconds block time, ~6000 transactions per block |
The official Golang implementation of Scdo. Scdo is an open source blockchain project which consists of advanced sharding technology and the innovative anti-asic MPoW consensus algorithm. https://scdo.pro
The current mainnet release: Scdo mainchain is powered by a new anti-ASIC consensus PoW algorithm, which requires scientific calculation related to matrix. MPOW PAPER The mainchain has four shards. It can perform transactions within a shard or crossing shards. However, smart contracts currently can be only executed within the same shard. Scdo subchains are under development. Scdo Stem subchain protocol. The so called EDA consensus algorithm EDA PAPER from Scdo will be utilized for the subchains.
Download (without building)
If you want to directly run the node and use client without setting up the compiling enviroment and building the executable files, you can choose right version to download and run:
| Operation System | Download Link |
|---|---|
| Linux | [https://github.com/scdoproject/go-stem/releases] |
| MacOs | [https://github.com/scdoproject/go-stem/releases] |
| Windows | [https://github.com/scdoproject/go-stem/releases] |
Or Download & Build the source
Building the Scdo project requires both a Go (version 1.7 or later) compiler and a C compiler. You can install them using your favourite package manager. Once the dependencies are installed, run

Building the Scdo project requires both a Go (version 1.7 or later) compiler and a C compiler. Install Go v1.10 or higher, Git, and the C compiler.
-
Clone the go-stem repository to the GOPATH directory:
go get -u -v github.com/scdoproject/go-stem/...
- Once successfully cloned source code:
cd GOPATH/src/github.com/scdoproject/go-stem/
- Linux & Mac
make all
- Windows
buildall.bat
Run Scdo

For running a node, please refer to Get Started(Older version). For more usage details and deeper explanations, please consult the Scdo Wiki(Older version).
Contribution
Thank you for considering helping out with our source code. We appreciate any contributions, even the smallest fixes.
Here are some guidelines before you start:
- Code must adhere to the official Go formatting guidelines (i.e. uses gofmt).
- Pull requests need to be based on and opened against the
masterbranch. - We use reviewable.io as our review tool for any pull request. Please submit and follow up on your comments in this tool. After you submit a PR, there will be a
