ChromaWay Know-how: The Power of Relational Blockchain and Rell

In recent years, blockchain technology has gained significant attention and adoption in various industries. Blockchain's key features of transparency, immutability, and decentralization have made it a popular choice for creating trustless and secure systems. However, the existing blockchain frameworks are primarily designed for storing and verifying data, making it difficult to use them for building complex applications. ChromaWay, a blockchain platform, has introduced the concept of relational blockchain, which provides a more flexible and powerful way of building blockchain-based systems. In this article, we will explore ChromaWay Know-how, the power of relational blockchain, and the Rell programming language.

Relational Blockchain - What is it?

A relational blockchain is a blockchain system that allows the creation of custom data structures and relationships between them. Unlike traditional blockchain systems that only support storing and retrieving data, relational blockchain allows developers to create complex data models and relationships, making it easier to build decentralized applications. ChromaWay's relational blockchain uses a unique data model called the postchain, which is a combination of a blockchain and a traditional relational database.

Postchains can support complex data models with multiple relationships, and users can interact with them using SQL-like queries. This makes it easier to build applications that require complex data structures, such as supply chain management systems, voting platforms, and identity management systems.

ChromaWay's Know-how Platform

ChromaWay's Know-how platform is a complete solution for building decentralized applications using relational blockchain technology. The platform includes a suite of tools, including the Rell programming language, a development environment, and a deployment system.

Rell - The Relational Programming Language

Rell is a relational programming language specifically designed for developing decentralized applications on ChromaWay's Know-how platform. Rell is similar to SQL in terms of syntax and semantics, making it easy for developers to learn and use. Rell allows developers to define custom data structures, relationships between them, and the business logic that operates on them.

Rell's syntax is optimized for building blockchain applications, and it supports transactional operations, such as atomicity and consistency, to ensure the integrity of the data. Rell's unique features, such as built-in caching and indexing, make it possible to build high-performance decentralized applications.

Comparing with EVM-based Blockchains

When comparing ChromaWay's Know-how platform with EVM-based blockchains like Ethereum, there are some significant differences that set them apart.

One of the main differences is the programming languages used to develop smart contracts. Ethereum uses Solidity, which is a statically typed language that resembles JavaScript, while ChromaWay's Know-how platform uses Rell, a relational programming language. Rell is optimized for developing blockchain applications, making it easier to develop complex data structures and relationships.

Another difference is the performance of the two platforms. Ethereum's EVM has some limitations in terms of performance, and as a result, it can only process a limited number of transactions per second. ChromaWay's Know-how platform, on the other hand, uses postchains, which are designed to handle large volumes of data and can scale horizontally. This means that the platform can handle a high number of transactions per second and is suitable for building large-scale applications.

In terms of adoption and usage, Ethereum has a larger user base and a more established ecosystem. However, ChromaWay's Know-how platform is gaining traction, and several projects are being developed on the platform.

When it comes to scalability, ChromaWay's Know-how platform has some significant advantages over traditional EVM-based blockchains like Ethereum. While Ethereum has been struggling with scalability issues for years, ChromaWay's Know-how platform uses a unique data model called postchains that allows for horizontal scaling, enabling it to handle large volumes of data and process a high number of transactions per second.

ChromaWay's Know-how platform has also implemented several security features to protect against potential threats. The platform supports multi-signature transactions, which require multiple parties to sign off on a transaction, making it more difficult for attackers to compromise the system. Additionally, the platform has built-in mechanisms to prevent double-spending attacks, ensuring the integrity of the data.

Despite these advantages, ChromaWay's Know-how platform is still in the early stages of adoption compared to Ethereum, which has a more established ecosystem and a larger user base. However, several projects are already being developed on the platform, and its unique features make it an attractive option for developers looking to build decentralized applications that require custom data structures and relationships.


ChromaWay's Know-how platform is a powerful tool for building decentralized applications using relational blockchain technology and the Rell programming language. The platform's unique features, such as postchains and Rell, make it easier for developers to build complex applications that require custom data structures and relationships. ChromaWay's Know-how platform is suitable for building decentralized applications in various industries, including finance, supply chain management, and identity management, among others. With ChromaWay Know-how, developers can focus on building their applications without worrying about the underlying infrastructure, making it easier and faster to develop and deploy decentralized applications.
