What is RChain?

Established in 2017 and based in Seattle, Washington, RChain is a cooperative that has introduced one of the robust Smart Contract platforms, known as RChain. It is fundamentally a new Blockchain platform rooted in a formal model of decentralized and concurrent computation. RChain uses that model through correct-by-construction software development and produces a compositional, concurrent and hugely scalable Blockchain.

Vision

The vision of the company is to change the world through the evolution of Blockchain technology. RChain believes that even being just a tiny portion of that change can have a profound impact.

In our world, a massive amount of waste is happening today; waste of energy, mindshare and government control. RChain’s outlook is to help eliminate as much waste as possible. Building a Blockchain technology with broader applicability, evenly applicable to people worldwide and less resource-intensive, can help reduce wastage.

An extensive community is required to grow and create something with a level of trust and usefulness that everyone everywhere can utilize.

Who is behind RChain?

The RChain Cooperative is a global entity that is owned and governed by its members. The entire RChain ecosystem gets its strength from its co-op members who rigorously work to bring innovation through constant governance models and empowering individual agency within a collective.

Community

The heart of RChain is its community. Community unites the world for building innovative technologies and social tools. Intending to lift the world and bring real, positive change, RChain builds a global community to flourish with each other. RChain invites active evangelists to join its community and become a member. The engagement with the RChain community can be accomplished through various platforms:

The current CoinMarketCap ranking of RChain is #258. REV is RChain’s cryptocurrency. It tokenizes the network’s security on RChain’s root shard, enabling staking and preventing DOS attacks. The advent of the mainnet enabled RHOC token holders to receive an equal number of REV tokens and add them to their REV wallets. RHOC was an ERC-20 token based on the Ethereum platform.

What problem does RChain solve?

Scalability issue

Each node in the network ecosystem has to process every transaction, share the nodes and produce transactions in parallel. With the constantly increasing number of transactions, the network gets overburdened and slows down the transaction processing.

The factors that lead to scalability problem are:

  • Limitations
    During transaction processing, every node adds information about the transaction to the ledger. It increases the recorded data and leads to the risk of buckling the overall system. Early blockchain like Bitcoin has the scalability problem and involves several limitations on the hardware side. It becomes challenging to run a node for two big Blockchains.
  • Block size
    Block size is another significant factor for blockchain scalability. Initially, every block’s capacity in the Bitcoin blockchain was 1 MB containing around 2020 transactions. Later, the number of transactions was increased, leading to another scalability problem: the time-consuming process of transaction execution.
  • Response time
    Every transaction needs to go through a validation process. The massive number of transactions in the queue leads to a long waiting time for validation. BTC network takes about 10 minutes to create a new block. With the increasing number of transactions, the processing time also gets increased.
    The process of transaction validation is carried out by adding it to a block in the chain. The new block is created and data related to that transaction is inserted. When users transfer cryptocurrency to one another, the payment information is sent to the node, a new block is created and data is added to it.

Ethereum’s solution

Ethereum proposed a solution for the scalability issue. Ethereum’s solution stored the state of the virtual computer instead of keeping the ledger. The specific rules for state transition from block to block are defined by EVM (Ethereum Virtual Machine). For a given input, it produces deterministic output. The state transition function is defined as:

Y(S,T)=S’

where S is the old valid state, T is a new set of valid transactions, Y is the Ethereum state transition function and S’ is the new valid output state.

RChain’s take on Ethereum’s solution

RChain states that Ethereum’s solution is based on the Turing machine’s model where an event starts, it runs to completion and it’s done. Ethereum’s answer to this issue as it is currently conceived cannot scale. It is because the virtual computer they pick is sequential. It would require serializing all the transactions over the world. Also, the Proof-of-Work ethereum uses are expensive due to the thermodynamics involved.

RChain’s Solution

Sharding

RChain proposes a sharding solution. It divides the network into pieces such that the whole network doesn’t need to validate everything happening everywhere else. With increasing nodes, a blockchain requires every node to verify each transaction in the network, slowing it down. RChain enables nodes not to keep the entire history localized and thus reduces the burden on the nodes and speeds up the transaction processing.

Proof-of-Stake

RChain replaces Ethereum’s Proof-of-Work with Proof-of-Stake.

  • Stake-based systems eliminate computing resource waste.
  • It distributes the imbalanced blockchain economic model.
  • It’s an emerging distributed system with transparent, participatory incentives.
  • It is a sustainable model for unlimited growth and scale.

Consensus algorithm

RChain implements a new, improved consensus algorithm. One of the essential things about RChain’s consensus protocol is that it has finalization. It means the nodes do not need to remember everything before a defined state. Validators are enabled to compact their state.

So, at a certain point, it can prove that all the different arcs of the DAG have to come through a particular state and thus, nodes can forget everything before that state. However, at the time of audits, people can go to the genesis block and perform data warehousing to get the entire history of the ledger. It also makes the network more robust. It means that it allows adding more nodes with lower cost and verify as many nodes as possible. It implies more nodes bring more security to the network.

Block merge

RChain implements Block merging with improved concurrent virtual computers to bring horizontal scalability. It gives a DAG (Directed Acyclic Graph) instead of a chain. When two blocks come in and build on some base state, it is essential to check if both are safe to make a transition without re-running all the computations. Rholang provides the functionality to detect if there’s any conflict with low complexity. It is done at a blazingly fast pace and thus enables to figure out a situation where two blocks are built side by side on top of the base state. Hence, instead of running transactions end to end, they are now running simultaneously, leading to exponentially increased throughput.

On what technology does RChain work?

RSpace

RSpace is a Scala library that is designed to provide disk-backed tuple space to the Rholang interpreter. Greg devised a version of Microsoft BizTalk Process Orchestration, updated the idea to use delimited continuation in SpecialK and finally proposed the RSpace design as a further refinement. It is an open-source store that fits into decentralized public infrastructure and its features and functionalities are acquired from a specific concurrency semantics embodied in Rholang.

Rholang

Rholang is a new concurrent programming language that is behaviorally typed, focusing on message-passing and higher-order extension of π-calculus. It requires the model of computation of the virtual machine whose state is stored on the blockchain must be concurrent rather than sequential. RChain states that the code which doesn’t take advantage of concurrency cannot scale. Likewise, a code that isn’t concurrent will fail to be responsive.

Concurrent programming is multiple times harder than sequential programming. Significant support from static program analysis is required to save the code from becoming overwhelming with the increasing number of programmers writing concurrent codes.

Namespaces and Sharding

The standard addressing scheme on the internet, URIs and URLs, is essential for keeping the entire web organized and identifying a powerful feature that rho-calculus refines: namespaces. URIs help to manage the web into trees of resources.

The namespace feature is highly critical in the market because most transactions are isolated. A programmatic way is required that can help to segment, organize and re-organize transactions and group them in terms of their shared resources. It is called sharding in blockchain space. The namespace capability of rho-calculus provides a powerful approach to sharding.

Operational semantics

The rho-calculus supports Turing’s complete operational semantics of Rholang core features. Every Rholang’s feature is defined in terms of mapping back to core calculus. It means that language is correct by construction. A clean operational semantics is necessary to identify when a program is substitutable. It is crucial to determine when it is safe to put a program in place of another in the broader execution context.

OSLF algorithm

OSLF algorithm, developed by Meredith, is such an algorithm that generates type systems. Given:

  • a notion of computation, like the one in the specification of JVM or semantics of Standard ML or Rho-calculus
  • a vision of a set-like collection
  • a distributive law that can show how to term with a hole in it

OSLF generates a type system. RChain claims that this type-system is much richer than those found in Java, Scala or Haskell. It can visualize program structure and behavior that older systems don’t have.

Casper

Casper is a new consensus algorithm designed by RChain. It includes stake-based bonding and betting cycles that result in Consensus. This consensus protocol aims to ensure the consistency of blockchains based on namespaces across various nodes. RChain’s Consensus is based on proof-of-stake protocol. The validators are bonded with a stake that is a security deposit placed in an escrow-like contract. RChain’s betting is based on logical propositions, a set of statements about blockchain, for example, “transaction T should occur before transaction S.”

Scala

Scala is a strong statistically typed general-purpose programming language for both functional and object-oriented programming. It is used for various software application development, ranging from machine learning to web app development. Developers using Scala have the advantage of making good use of standard JVM features and Java libraries.

What are the powerful tools/ SDKs/ frameworks used by RChain?

RChain implements the following tools/ SDKs/ frameworks:

  • Javascript library: It is a library of pre-written Javascript code snippets that enables easy Javascript-based application development. A required specific library code is plugged into the rest of the project’s code and is re-used according to the needs.
  • Java SDK: The development kit implements either one of the Java platforms, Standard Edition, Enterprise Edition or Micro Edition, launched by Oracle in binary products aiming at Java developers on Linux, Solaris, Windows or macOS.
  • Android SDK: It is used to create Android applications usually written in Kotlin, Java and C++ programming languages. It contains a comprehensive set of tools, including a debugger, handset emulator, libraries, documentation, sample code and tutorials.
  • dotNet SDK: It is a set of libraries and tools that allow developers to create dotNet applications. The main components to build and run applications are .NET libraries and runtime, .NET CLI and .NET driver.
  • REST API – Mainnet – Master Node: The REST API conforms to the constraints of REST architectural structure and enables communication with RESTful web services. Sometimes, it is also referred to as a contract between information provider and user.
  • Redux library/API: It is an open-source Javascript library used to manage the application state. It is most commonly used for building user interfaces with React or AngularJS.
  • IDE Support – Cryptofex: Cryptofex is an integrated development environment that supports writing Blockchain Smart Contracts.
  • IntelliJ Plugin: It is a Java-based IDE for developing computer software. IntelliJ helps to analyze code, looks for a connection between symbols across all project files and languages.
  • Emacs Plugin: Emacs is a family of text editors who are characterized by their extensibility. The popular GNU Emacs is an extensible, customizable, self-documenting and real-time display editor.

What opportunities does RChain provide?

RChain is set to accept all kinds of engagements, whether it is work on business development, community development or software development for financial guidance, acquiring tokens or business partnership; RChain values all.

dApps

The most significant factor driving network adoption is the total volume of transactions on the network. The most crucial factor that drives this volume of network transactions is dApps or decentralized applications. dApps run on the blockchain or P2P networks, having decentralized environments free from central control and interference by any single authority.

Developers engagement

RChain offers a grounded, unique combination of technological innovation and economic opportunities. While the current emphasis is on microservices, blockchain revelations about distributed Consensus and internet-scale applications, a shift towards Protocol Oriented Programming (POP) is a high likelihood.

Validators

Tremendous interest is seen for RChain’s CBC-Casper, proof-of-stake and running RChain validator nodes. The RChain Cooperative has initially run most nodes in the root shard but eventually will shift to a more decentralized distribution of nodes. However, the hardware for the backbone of the root shard is very high-end to get the contemplated transaction throughput.

Tokens

Every dApp on the network will require a REV token when RChain achieves critical mass network effects and will constitute a vibrant ecosystem of services, including decentralized maps and location services, decentralized Uber and AirBnB and decentralized payments.
