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
