Chroma is an open-source public blockchain developed by Chromaway AB, a Swedish company. Launched in May 2019, Chroma is based on a technology known as 'Postchain,' which was initially designed for enterprise clients. This innovative blockchain aims to provide enhanced functionality for decentralized applications (dApps) through its unique architecture and programming language. As a standalone Layer-1 blockchain, Chroma also offers an EVM-compatible Layer-2 solution for Ethereum and Binance Smart Chain. Its design focuses on improving scalability, data management, and customizable fee structures for dApps. The blockchain's relational architecture and the custom programming language, Rell, allow developers to create applications that leverage blockchain security while efficiently managing data akin to traditional relational databases. Each dApp on Chroma operates on its own sidechain, which is linked to the main blockchain. This structure enables better scalability and provides developers with flexibility in fee arrangements. For instance, one application might require transaction fees in Chroma tokens, while another could allow users to make unlimited transactions by staking CHR for reserved computational resources. Chroma has already attracted a diverse range of applications, including a DeFi options trading platform, a farming simulation game, and a government land registry initiative. Additionally, the platform is working on an NFT standard called Chromia Originals, which will enhance both its own chain and existing token standards. The development team behind Chroma includes experienced professionals with a rich history in the cryptocurrency space, contributing their insights and expertise to drive the project forward. Overall, Chroma aims to revolutionize the way decentralized applications operate with its advanced features and innovative data handling capabilities.
