关于 Chromia

Why choose between a traditional database and a blockchain when you can have the best of both worlds? The Relational Blockchain is a new architecture that combines the power and flexibility of mature database systems with blockchain's secure collaboration and disruptive potential. Chromia is a relational blockchain platform for decentralized applications (dapps).

While platforms, such as Ethereum, allow any app to be implemented in theory, in practice, they have many limitations: awful user experience, high fees, frustrating developer experience, and poor security. This prevents dapps from going mainstream. Therefore, we conceived and designed the relational blockchain to enable a new generation of dapps to scale beyond what's currently possible.

Most dapp blockchain platforms use virtual machines of various kinds, but a traditional virtual machine architecture doesn't work very well with the Chromia relational data model, as we need a way to encode queries as well as operations. To enable this, we created a new language called Rell (Relational language) for dapp programming.

When developing a dapp, you can write the backend in Rell and deploy it to the Chromia platform. Chromia also has client libraries for building transactions on the frontend. The client side then sends the transactions to the Rell backend.

Chromia is a general-purpose platform capable of serving almost all kinds of dapps. It's particularly well suited to cases requiring high I/O capacity or involving the management of complex data sets. At the same time, it offers the same level of openness, security, transparency, and decentralization as other public blockchains. To understand when Chromia blockchain is the best choice, you need to dive a bit deeper:

Real-time transactions: With Chromia's blockchain, transactions can be confirmed within ~1 second, enabling unparalleled performance. Each dapp on Chromia has its own blockchain run by a set of nodes using PBFT-style consensus.

Relational blockchain: The unique architecture and relational blockchain enables flexibility, versatility, and consistency, which traditional relational databases are known for. In addition, it allows for traditional database operations, empowering developers to be productive in an already familiar design pattern.

Rell language: Chromia provides a blockchain platform written in Rell. Rell is a relational language designed to be easy to learn and developer friendly. The language is deliberately like modern programming languages, and developers can use relational programming idioms they're already familiar with.

%name%Roadmap

  • Consensus system: EBFT

  • Our consensus method is based on PBFT, but is our own custom implementation from the ground up. It is robust and flexible, built for Chromia’s massive horizontal scale.
  • Rell 0.7: the first Rell runtime with full interpreter

  • Rell continues to evolve with every passing day, but the first version with a fully implemented interpreter was a major milestone. That was when Rell became a full-fledged blockchain programming language.
  • FT3 & SSO

  • Flexible Tokens is the Chromia token standard, supporting fungible and non-fungible tokens of arbitrary complexity, as well as implementing Chromia SSO, a decentralized authentication scheme which allows seamless login to dapps without exposing the root keypair.
  • Blockchain dependencies

  • Blockchain dependencies were a key milestone on the road to the hierarchically interconnected blockchain networks which support Chromia’s massive scale. Allowing one blockchain to pull data from another means not just greater efficiency, but also the ability to use decentralized governance to update configurations and parameters for dependent blockchains.

  • Postchain 3 release

  • Postchain 3 was the third major release of Postchain, the relational blockchain technology which underpins the Chromia platform. Postchain 3 featured a mature transaction scheme (GTX) with a full value serialisation model (GTV), and proof extractor.
  • Postchain managed mode

  • Managed mode allows a Postchain network to infer its own configuration (signers, validators, observers, pruning, historic configurations) from another blockchain. This abstracts the maintenance and updating of nodes from the node operator, allowing update operations to be safely coordinated in a decentralized way.
  • Special transactions

  • A new facility which allows block producer nodes to play a more active role and inject data into a blockchain. Block producers need to form consensus about the data being injected in the same way they do it for blocks. This feature is uniquely suited for creation of layer-2 blockchains, as data from parent blockchains can be injected and be subject to consensus.
  • Vault

  • The Chromia Vault is our wallet software and dapp portal. It allows for token management and decentralized authentication to dapps running on other chains. It is itself a decentralized application.
  • Explorer

  • The Chromia Explorer is a decentralized blockchain explorer, possibly the first of its kind in the world.
  • Postchain synchronization system overhaul

  • Adding the possibility to sync a blockchain from any node which has a copy of it, and increasing the robustness of the synchronization subsystem. Previously it was only possible to sync from current block producers.
  • Block hooks

  • This feature makes it possible for any Chromia blockchain to automatically perform an action at the beginning or end of any block.
  • Containerized resource management for dapps

  • Framework for resource management for dapps across provider nodes, enabling decentralized resource allocation.
  • Ethereum L2 base subsystem

  • The base set of L2 functionality in Chromia consists of a number of facilities including:

    account state snapshots
    event commitment
    external chain event injection
    Chromia data validation in EVM
  • Cross-chain communication subsystem

  • Currently cross-chain interaction is possible via confirmation proofs. While sufficiently general, this isn't particularly robust as it depends on clients to inject events. Using special transactions and ephemeral dependencies we can enable more direct cross-chain communication where block producer nodes will be responsible for facilitating communication directly on blockchain core level.
  • Ephemeral dependencies

  • This feature builds on the previously implemented 'blockchain dependencies' feature, which allows one blockchain to directly read data from another. A capability that is, as far as we know, unique in the blockchain world.

    While very powerful, it has a limitation: if blockchain A depends on blockchain B, we need to keep B around forever for blockchain A to be sync-able. This limitation limits ability to re-architect and optimize the system. This is particularly essential for system blockchains which need to be future-proof. Ephemeral dependencies would allow developers to remove dependencies over time when they are no longer needed.
  • Dev chain launcher

  • Tools to instantiate a blockchain in “development mode” to make it easier to develop and test dapps in simulated environments.
