A word from our CTO

A quick word from our CTO Alex Mizrahi about the Chromia project and the most effective way of communicating our objectives and progress to the community.

“We are 100% committed to delivering the platform that we outlined in our white paper, that is certain. The scale of this project should not be underestimated; we are building something entirely new from the ground up, there are many unknowns and the stakes are high.

When working on something entirely new, it is very difficult to forecast how long things will take because there is no precedent or history to base estimates on.

Similarly, while we can predict upcoming features, it is difficult to chart our long term milestones because of the enormous breadth of possibilities and branching paths which we might follow to reach approximately the same destination.

Finally, we work agile! That means that we are constantly reassessing our priorities and tasks, and incorporating feedback from the community to inform our decision making. We know that the market craves certainty and predictability, but tough lessons in the software industry have shown time and time again that the forecasts of fixed roadmaps and waterfall development will very likely fail to materialize. We, along with most of the software development world, prefer to embrace uncertainty and flexibility rather than expend our resources creating the illusion of predictability.”

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.

done

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.

done

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.

done

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.

done

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.

done

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.

done

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.

done

Explorer

The Chromia Explorer is a decentralized blockchain explorer, possibly the first of its kind in the world.

done

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.

done

Block hooks

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

While this may seem like a minor feature, the lack of it can create issues for dapp developers. For example, Maker CDPs can go bad if there is no mechanism to trigger liquidation, while on Chromia you can make it fully automatic and independent of outside actors.

done

Containerized resource management for dapps

Framework for resource management for dapps across provider nodes, enabling decentralized resource allocation.

done

Ethereum Interoperability Framework (EIF)

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

in progress

Hardened Bridge (H-Bridge)

The hardened bridge will be built on top of EIF and allow for the secure bridging of assets between the Chromia Network and Ethereum, as well as other EVM chains.

in progress

ICMF (Interchain Messaging Facility)

ICMF enables more direct cross-chain communication based on pub-sub architecture, facilitated by block producer nodes and validated on the blockchain level. The end result is robust communication between chains on the Chromia Network, which can take place in an automated fashion without relying on end users to initiate events and transactions. ICMF is necessary for both the Directory Chain and the Hierarchical Anchoring system to function.

in progress

Directory Chain

The Directory Chain is responsible for coordination of the Chromia network as a whole. It stores all information needed to run the network, such as a list of providers and nodes, and configurations (code) of all blockchains on Chromia network. The ability to look up in the directory chain enables secure cross-chain interactions.

in progress

Hierarchical Anchoring

Chromia nodes are arranged in clusters which run blockchains. Hierarchical Anchoring allows the headers of all the blockchains within a cluster to be serialized and committed to an anchor chain, which can then itself be committed to a system level anchoring chain or further to an external blockchain such as Ethereum. This solution allows our anchoring to scale to an almost unlimited number of clusters.

in progress

FT4 Token Standard

Chromia’s “Flexible Token” (FT) standard supports all fungible and non fungible assets as well native CHR tokens. After collecting feedback from our internal team and ecosystem partners regarding FT3, work has begun on FT4. This new version will introduce Metamask compatibility and improve security by implementing built-in spending policies that allow more precise access delegation.

in progress

Chromia Mainnet Launch

When the above components are completed, tested, and audited, the Chromia mainnet will be launched. Mainnet operation will be continuously optimized and upgraded moving forward into the future.

in progress

Chromia Testnet Mark 2

When the above components are completed, they will be deployed in a testnet environment to ensure functionality and operational security before mainnet launch.

planned

Dev chain launcher

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