Motivation

There are two huge problems around cryptocurrencies development project Scorex aims to help to solve:

* Bitcoin source code contains more 100K lines of code(80K of C++ only), Nxt is about more than 45K lines of Java code. All parts of the design(network/transactions/consensus layers) are mixed in a hard way.  So researchers & developers are definitely not in a good start position to make any experiments.  In opposite, Scorex is less than _4K lines of Scala code_. Transactions layer is as simple as just tokens transfers. Consensus algo  could be switched easily(with two consensus algos out of the box,  one could be replaced with an another with just one line of code edited!)

* Major coins forks are trying to make IPO immediately, often having just one or two pretty controversial features introduced. **Scorex is intentionally not production-ready**, so please participate in any  non-commercial experiments built on top of it, but don't buy tokens unless you are 100+% sure what are you doing.
 

Features

* Two 100% Proof-of-Stake consensus algos out of the box, Nxt-like and Qora-like. One algo could be replaced
with an another with just one line of code edited (in Constants.scala)
* Simplest transactions model
* Asynchronous network layer on top of TCP(with Akka I/O)
* JSON API
* Command line client for the JSON API
* Curve25519 for signatures
* CC0(Public Domain) license
* Compact, functional, actors-powered code
* Scala / Akka
 

Roadmap

This release is named Lagonaki (after picturesque mountains resort in West Caucasus https://yandex.ru/images/search?text=%D0%BB%D0%B0%D0%B3%D0%BE%D0%BD%D0%B0%D0%BA%D0%B8 ), the current version is 1.0. It is the initial release aiming to provide modular and simple product to improve.
     
There are some issues/todos to be solved in upcoming 1.1 then 1.2 versions.           
 
And new branch will be forked very soon, with a brand new Proof-of-Stake algo having no whitepaper atm. More details soon. Nxt forging algo improvement proposal will be derived then from testing results. 

Authors

Scorex is made by [Consensus Research microteam](https://github.com/ConsensusResearch) previously worked on Proof-of-Stake investigation:

Alexander Chepurnoy aka kushti - Nxt developer & smartcontract.com cofounder. Has few published papers in Computer Science field(finite state systems related), writing PHD at the moment.   

andruiman - serial entrepreneur with theoretical physics background, a big fan of Coq interactive theorem prover & functional programming.

Repository URL

The main link to follow is the GitHub repository:

The only place we can view information on this is on GitHub?

I'm going to have a lot of fun with this tool.

Thanks kushti and arduiman

Right, 2 files on GitHub(API/Readme) + source code. Will write some docs on architecture / details.


With PoS it's simpler to run smaller networks, even a single running blockchain on a local machine. Both PoS algos implemented are pretty simple in fact 

First Scorex devs meetup is coming! Aug, 14th, Saint-Petersburg, Russia. Going to publish some design docs before that.

The first article describing architecture of almost every cryptocurrency of today has been just published: https://github.com/ConsensusResearch/Scorex-Lagonaki/blob/master/docs/components.md

LOL. Did you actually read the post to see what this is?

Great project.  Very educational.

Is it compatible with proof-of-work?

The meetup was very productive and insightful, finally we've came to conclusion to split the project into separate layers explicitly using following artefacts:

1. scorex-utils - cryptofunctions and other functionality not corresponding to a cryptocurrency logic directly
2. scorex-network - p2p layer
3. scorex-consensus - consensus-related data sctructure & functions
4. scorex-transaction - transactions handling code and internal state


So to change consensus from PoS to PoW it would be enough to swap from scorex-consensus-pos to scorex-consensus-pow.

I'm going off for few days to return with a roadmap.

I'm going to release 1.1.0 during this week, snapshot version is online. Just finished new article about new modular design, could be fun for devs: "On the Way to a Modular Cryptocurrency, Part 1: Generic Block Structure" -> https://github.com/ConsensusResearch/Scorex-Lagonaki/blob/master/docs/modular1.md
