RChain Publishing plans to airdrop its RPC tokens to all REV addresses when its mainnet goes live soon after March 30. A “snapshot” of all REV balances was recorded on April 3 and can be inspected here: wallets.txt

Secure. Scalable. Sustainable.

RChain® Cooperative is building the only concurrent blockchain platform as well as 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™ is the native digital token for use by members of the RChain Cooperative on-line community via a global computer network. It tokenizes the security of the network's root shard, preventing DOS attacks and enabling staking.

Technical roadmap

RChain is the only leaderless smart contract platform to allow safe concurrent execution of smart contracts in a single shard, and therefore achieves linear scalability. This feature is the result of 30+ years of research in concurrency and process calculi. Robin Milner specified the Pi Calculus in the 90's and was awarded with a Turing prize for his work, RChain is powered by the Rho calculus which enhances the Pi Calculus.

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

RChain realizes superior scalability and speed by doing intelligent concurrency throughout the network and right-sized validation of every transaction. 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

RChain is built in a radically open source fashion. The contributions of Cooperative members enrich and extend the RChain ecosystem.

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

  • July 2021Block Merge v2 on Testnet

    Q4 2021History performance improvement

    Q4 2021Leaderless Block merge (LLBM) Hard Fork 2 (version 1) on Testnet

  • Future

    (H1 = 1st half, H2 = 2nd half)
  • H1 2022Leaderless Block merge including finalization - Hard Fork 2 on Mainnet

  • H1 2022PoS 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.
  • H1 2022Hard fork 3 for POS and enable future soft forks

  • H1 2022On-Board 3rd Party External Validators

    Create a decentralized network by expanding the number of external 3rd party validators that secure the network.
  • H2 2022Rholang v1.1 Operationalization

    Implement Rholang v1.1
  • H2 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).
  • 2022Improve Developer Experience

    Will be delivered incrementally throughout the year.

    2022Network Hardening and Bug Fixes

    Will be delivered incrementally throughout the year.

    2022Thread mapping

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

    2023KPI 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
  • 2023Basic Behavioral Types

    Type safety with data query functionality.
  • 2024Rholang Chip (Bare Metal)

    Substantial performance increase
