Chromia is a relational blockchain platform designed to enable a new generation of dapps to scale beyond what is currently possible.

We are introducing our IEO.

Hello Chromia

Chromia (by ChromaWay) is a new blockchain platform for decentralized applications, conceived in response to the shortcomings of existing platforms and designed to enable a new generation of dapps to scale beyond what is currently possible. Chromia is both a blockchain and a relational database. This means that decentralized applications (dapps) can be written in a way that is familiar to developers all over the world, whether they work on large enterprise applications, games, or smaller projects.

Fully Functional dapps

Dapps do not arise from “smart contracts” in Chromia, but are considered first-class entities: each dapp blockchain runs on a specific set of nodes and typically have their own dedicated CPU thread. If a dapp needs more than one execution thread, it can consist of multiple shards, each of which will be a sidechain. That gives dapp developers a high degree of flexibility and control.


Rell is a language for relational blockchain programming. It combines the following features: Similar to SQL. People familiar with SQL should feel at home once they learn the new syntax. Safety-optimized. Arithmetic operations are safe right out of the box, programmers do not need to worry about overflows. Concise, expressive and convenient. As a data definition language, Rell is up to 7x more compact than SQL. Allows meta-programming. Programmers can use relational programming idioms they are already familiar with. Rell aims to make programming as ergonomic as possible. It minimizes boilerplate and repetition. At the same time, as a static type system it can detect and prevent many kinds of defects.
