Greg Meredith & Nash Foster
RChain – The Scalable, Concurrent and Performant Blockchain

EPISODE 221
FEB 8 2018
67 MIN
We’re joined by Greg Meredith and Nash Foster of the RChain Cooperative. A fundamentally kind of new blockchain platform, RChain is rooted in a formal model of concurrent and decentralized computation. Powered by the Rho Virtual Machine, and secured by Casper proof-of-stake, RCain is partitioned, or shareded by default, forming a network of coordinated and parallel blockchains. The project, which is formed as a coop, leverages correct-by-construction software development to produce a concurrent, compositional, and massively scalable blockchain.

Topics we discussed in this episode
How Rchain spun out of the Synereo project
The primary objectives RChain seeks to establish
The fundamental principles of RChain and RLang
The concepts of concurrency and parallelism in simple terms
How building concurrent systems implies scallability
The unique features of Casper consensus in the context of RChain
The importance of namespaces in RChain
Why this project was started as a cooperative
The current status of the project and roapmap

No ICO has been conducted yet. Private sale in september 2017 was 0.20 and 0.30 for the December 2017 private sale

Yes, we are formally verified! That means the math proves it can be done. We are now in the engineering stage and the brief roadmap can be found here : https://rchain.atlassian.net/wiki/spaces/CORE/overview

Development update for the week of 22nd Jan 2018:

 - Roadmap - Draft version in review with Dev team.
 - Planning for Sprint entry next Monday
 Focus on delivering the SDK 0.1 by end of January.
 - Updated Rholang specification & tutorials expected by end of day
 - Line numbers for Lexer errors and compiler errors implemented.
 - Packaging in Docker container complete, waiting for final binaries.
 - Rosette is ready- we have 1 Segfault ticket we are looking at
 - We will offer a download version of the web compiler
 - developer.rchain.coop website in flight.
Compiler team is concentrating on what features are needed in Rholang for Mercury
 - High level Compiler roadmap ready.
 - Documenting our plans for Lexical Namespaces, looking at a variant of Pi Calculus that Greg recently  - developed - work continues.
 - Specify Crypto primitives in collaboration with VM team.
 - Tuplespace and storage - discussion planned this week.
 - Cost estimation simplified, contracts will need to be run in test net or locally in order to get a cost estimate.
 - CASPER: Byteball as a CBC Casper variant done.
Node team:
 - Specify Communications API's in Node.
 - Flesh out how the Node, Storage and VM come together.  Meetings this week to sort it out.
 - Node Community test completed - we had ~ 25 nodes participate!
 - CI for Node Docker, so we can continuously cut builds.
 - Henry Till joins the team, focus is leading storage development.
 - Lots of unit tests developed for storage work on greenery and path to regex library ports.
Rosette team:
C++ :
 - Work to support SDK release.
 - Investigate Debug Mode- ROS-327
 - Rosette VM Specification - Reverse engineer Primitives
 - Design discussions around 64 bit C++ VM
 - Found and fixed a bug for constant matching for argument patterns.
Scala team: Did some work on the RBL compiler, had to stop to focus on OpCodes - heavy sprint commitment on track.

Node testing going on right now. Please head to the #node-testing channel in Discord (Public): https://discord.gg/fvY8qhx for more details

Node testing on Thursday 18th 8:30 AM PST. Will appreciate help from those who can run a node.

From Nash E. Foster Cofounder & CEO, Pyrofex Corporation in the Telegram channel:

The Coop’s developer team is pleased to announce the initial milestone release of our RChain node software--Node.Hello (v0.1). This package marks the first of many pre-production release milestones along our flight to Mercury. This pre-alpha software release demonstrates the RChain network communications system and is available for interested parties to begin helping us test. Node.Hello will discover the RChain bootstrap node, detect other active RChain nodes, and form the RChain peer-to-peer network. The network layer is the lowest level component in the architecture that will eventually support RChain’s large-scale blockchain operations.

Detailed documentation on the release can be found in Github:

https://github.com/rchain/rchain/tree/v0.1/comm
In addition to building from GitHub, users may opt to download a Docker image from Docker hub here:

https://store.docker.com/community/images/rchain/rchain-comm
We invite all community members to test the code and provide developer feedback and ask questions:

Questions & Comments via our Gitter channel - https://gitter.im/rchain/Releases Bugs can be filed on our Jira using this link - https://goo.gl/DdP48u

Please keep an eye out for additional milestone components in coming weeks. On behalf of the developer team, I’d like to thank the entire community for your support. On a personal note, I’d like to wish you all a very merry Christmas, I hope you have a wonderful holiday season.

Rchain Project Overview - High Capacity Ethereum Blockchain Killer

https://www.youtube.com/watch?v=OLQ4LVmCIh4

On this episode of the Crypto Coin Show I dive into the Rchain project which in my opinion is very undervalued and could even be the next Ethereum. Vlad Zamfir and Greg Meredith are planning to build the rchain network to handle over 40,000 transactions per second so the world can use cryptocurrencyall at the same time.

Hi All,

Medha would like to organize a Node stress test for Node.Hello.  For those interested please head to the discord channel #node-testing or ping her in the discord
​
Discord (Public): https://discord.gg/fvY8qhx

She will be organizing a time when we will get as many nodes up and running, so we can see how everything performs and will be reaching out to schedule a time with those of you that wish to participate.

Do participate in the node stress test if you can as it will be extremely helpful to us!

For the techincally savvy folks, they are running a node stress test if you guys can help out do join the stress test channel
