About
Chromia is a relational blockchain designed to make it much easier to make complex and scalable dapps. Chromia gives power to developers to give power to the public.
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.
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.
Features
Excellent user experience
Dapps on Chromia can achieve parity with centralized applications in terms of ease of use and make user onboarding process much simpler. Dapps which require complex UI, such as games, can be implemented using a separate client delivered as a web or mobile application. In this case security can be controlled through the use of sub-accounts. The dapp client will receive a private key of a sub-account which belongs to a user and will be able to sign transactions on behalf of the user. This means that the user can perform game actions in a natural way, similar to how “normal” games work.
Sustainable dapps
Chromia has Dapp level provisioning. It means the freedom of dapps to create their own fee and resource use policies. It also allows token economics to be integrated with the fee model, i.e. fees are taken from profits “earned” by an application. It also supports mechanisms for governance and dapp updates which are built-in to the platform.
Fast dapp load
Dapps can quickly retrieve information they need directly from nodes running the application. Dapp blockchain logic can perform complex queries without performance degradation. Thanks to rich indexing and query capability the entire Dapp state relevant to the user can be transferred to the client in a matter of seconds.
Unlimited scalability
Chromia allows dapps to scale to millions of users via horizontal scaling with sidechain sharding. Each dapp has its own blockchain(s). Because each blockchain is run by a subset of nodes, it is possible to increase total throughput by increasing the number of nodes.
High interactivity and i/o throughput
Data queries and updates are delegated to a heavily optimized relational database, allowing dapps to perform a large number (100k+) of queries, data retrievals and updates operations from blockchain within seconds.
Lightning fast transactions
PBFT-style consensus enables transaction confirmations within seconds. Chromia aim to support 50 million token transfers per day per blockchain in MVP version of software.Transfers can be confirmed within 2 seconds which should be enough to support in-person payments.
Chromia is a brainchild of ChromaWay. ChromaWay has a long record of delivering pioneering projects around the world. We issued Euros on the Bitcoin blockchain with LHV bank, allowed investors to invest in startups in a wholly decentralised way with Funderbeam, digitized the title transfer process with the Swedish land registry, and mediated the green bond market with SGDF. ChromaWay’s core team created the world’s first protocol to issue tokens already in 2012, when blockchain was called “bitcoin 2.0”. Then, ChromaWay introduced the relational model to enterprise blockchains with a consortium database called Postchain. Now Postchain is going public as the foundation for Chromia, a better blockchain for building decentralised apps. Chromia does not reinvent the wheel. ChromaWay is incorporating seven years of experience into something which is ready for the future. Chromia is the product of the many lessons we have learned over the years. Every problem that we have encountered has led to solutions and best practices that we have endeavoured to incorporate into Chromia so that users of the platform can focus on what is important: building world-changing dapps.
