Secure. Scalable. Sustainable.

RChain® Cooperative is building a blockchain platform and key social coordination technologies. It uses CBC-Casper proof of stake + rholang and aims to become the most powerful and widely used smart contract platform.

REV® tokenizes the security of the network on RChain's root shard, preventing DOS attacks and enabling staking.

The Rho Revolution

A breakthrough concurrent computational system that unshackles the blockchain


A Complete System

RChain is pioneering transparent and secure transactions with an ultra-fast, global scale technology platform. Cooperative governance and a sustainable economic model make RChain a public utility that can be applied to climate change, data security, digital identity, and many other challenges we are collectively facing.


Fast and Efficient at Every Scale

Intelligent concurrency throughout the network and right-sized validation of every transaction prevents wasted resources. Transactions now happen with low execution costs and greater efficiency.


Dependable and Secure for All Applications

RChain's decentralized architecture design does not compromise security to achieve scale. Rholang, RChain's contract programming language, lets developers write for concurrency and formally verify all processes.


Built, Nurtured, and Governed Cooperatively

An inspirational and radically transparent open-source cooperative. RChain's member-driven contributions enrich every part of the system, resulting in unlimited organic growth.

Technical Roadmap

  • Past

  • September 2018Launch of the RChain Testnet

    RChain Testnet goes live for validator node bonding and unbonding and smart contract deployment testing.
  • October 2018Launch of the name registry

  • January 2020Snapshot of Final RHOC Balances

    The RHOC token was a ERC 20 token based on the Ethereum platform. RChain’s native token is the REV token. With the advent of Mainnet, RHOC token holders received an equal number of REV tokens added to their REV wallet.
  • February 2020Launch of the RChain Mainnet

    RChain platform goes live with 10 Co-op validator nodes. Transactions are processing.
  • March 2020Epoch 1

    50M REV are staked on 10 Co-op validator nodes. Nodes transition from US-based nodes to international-base nodes.
  • July 2020Epoch 2

    72M REV are staked on 20 Co-op validator nodes.
  • December 2020Last Finalized State (LFS)

    LFS removes the blocks which lightens the blockchain. Having far fewer blocks to process for update creates greater efficiency which allows new node validators to quickly arrive at the current state.
  • December 2020Epoch 3

    90M REV are staked on 30 Co-op validator nodes.
  • December 2020Rholang v1.1

    Created Rholang v1.1 which offers code compression by a factor of 4x for common code structures and optimization on backend with communication and executing events with respect to RSpace.
  • March 2021Block merge v1 on Testnet

    rnode 0.11-alpha
    With the implementation of block merge the RChain network now scales horizontally in that as you add validator nodes, the network scales nearly linearly. Scalability is the ability to process a higher volume of transactions as you add either more nodes or more powerful hardware within a node.
  • July 2021Hard fork 1 for balances only

  • Future

  • August 2021Block merge v1 on Mainnet

  • August 2021PoS Contract Update to Enable External Validators

    Updating the proof-of-stake consensus smart contract allows external 3rd party validators to join and secure the network.
  • September 2021Hard fork 2 for POS and state reset

  • September 2021Block Merge v2 on Testnet

  • October 2021Block Merge v2 on Mainnet

  • Q4 2021On-Board 3rd Party External Validators

    Create a decentralized network by expanding the number of external 3rd party validators that secure the network.
  • Q1 2022Rholang v1.1 Operationalization

    Implement Rholang v1.1
  • Q2 2022Namespaces and Sharding

    A namespace is any collection of names: one name, two names, three names or more. A set is a collection of names. Channels facilitate transactions by acting as pathways. Channels live in namespaces. There are many many more transactions than there are names in a namespace. Implement child shards for interoperability (i.e. Ethereum and Bitcoin).
  • 2022KPI Dashboard

    The rchain.coop key performance indicator dashboard display metrics such as:
    • - Transaction (txn) volume per second, per minute, per hour, per day
    • - Resource usage by second, minute, hour, day: aggregated and by bandwidth, cpu and storage
    • - Number of validators connected, number of txn/validator/day, by owner
    • - Network decentralization: RChain node cloud diversity and 3rd party validators
    • - Uptime across network as %, uptime by node as %, by owner, issues outstanding, issues yesterday
    • - Number of contracts that fail to complete, number of contracts that fail to complete due to lack of resource
    • - Block creation time
  • 2022Thread mapping

    Logical threads to physical threads have linear scaling. Add more validators and achieve greater platform capacity.
  • 2022Behavioral Types

    Type safety with data query functionality.
  • 2023Rholang Chip (Bare Metal)

    Substantial performance increase
