What's Chromia?

Chromia represents an innovative Layer-1 blockchain ecosystem that hosts a new generation of highly-performant and scalable decentralized applications (dapps). Each dapp relies on its computational resources and hosts on the blockchain network, avoiding the centralization of services.

Costly network resources are a widespread problem for such blockchains as Ethereum, which means that dapps deployed to these networks:

  • Are expensive to run.
  • Lack computational resources needed for complex business logic.
  • Have low transaction throughput.

Chromia dapps can have zero gas fees and sustain loads such as massively multiplayer online games (MMOGs) running entirely on-chain. The capability to store terabytes of data enables the creation of complex and self-reliant, fully decentralized dapps.

The main priority of Chromia is to allow dapps to accommodate millions of active users while providing identical service performance as centralized applications.

No network congestion

Chromia's innovative blockchain scaling involves each dapp having its blockchain to handle user requests and manage its data. Dapps operate independently from each other, ensuring efficient processing and storage. When a dapp is under heavy load, developers can lease additional resources from the network to prevent a performance decrease.

This setup enables fast transactions, high throughput, and autonomy for each dapp without risking interference. Hence, the entire network avoids congestion since each network entity is responsible for its operations.

No direct gas fees

The ecosystem allows developers to implement a set of revenue models for dapps such as paid subscriptions, fixed fees, or even no fees. This eliminates the need for users to pay gas fees to interact with the dapp, allowing developers to choose their desired source of income. The monetization strategies include:

  • Subscription fee - Users can access services for a regular fee, ensuring stability with recurring revenue and flexible pricing options.
  • Fixed fee - Payment of a fixed amount to access your dapp's features, promoting trust and transparency by ensuring users know precisely what they're paying for.
  • Open fee - Allows using your dapp's features completely free. This fee model removes the entry barrier and allows users to freely explore your product.

To achieve high processing power on the blockchain, the Chromia network relies on providers - entities that maintain their own highly performant hardware. Developers can lease this compute power from the network for a specific subscription fee to host their dapps. This subscription model resembles traditional cloud hosting, where developers pay a predictable weekly fee for a known set of resources such as vCPU, RAM, storage, and IO to host their dapps.

Fully on-chain dapps and NFTs

Chromia distributes storage and computational resources among provider nodes, enabling Dapps to store program logic, metadata, and entire files on-chain, facilitating the development of intricate, fully decentralized dapps.

This principle also applies to NFTs; NFTs on Chromia can store all associated metadata and images directly on-chain. In contrast, NFT tokens on EVM chains are limited in their ability to store metadata, often requiring external services for images and supplementary data storage.

Rell programming language

Chromia takes a language-driven approach with Rell. This new programming language is designed explicitly for dapp development within the relational data model, making it familiar and easy for developers with existing experience to learn. Rell is concise, allowing developers to write sophisticated and secure dapps quickly and easily.
