Chromia protocols

Let's discuss the Chromia protocols, the foundational elements that enable secure digital ownership and interaction within the Chromia ecosystem. These protocols work together seamlessly to create a robust and versatile foundation for your digital assets.

First, we have the FT4 protocol, which is the backbone of token management and authorization in Chromia. FT4, or Flexible Tokens version 4, is the latest iteration of Chromia's token protocol, built with enhancements for better performance and functionality.

Meanwhile, Originals, a complementary protocol, focuses on describing the characteristics of tokens managed by FT4. It allows projects from various blockchains to migrate their metadata, images, and information to our network.

FT4 protocol

FT4, or Flexible Tokens version 4, is a protocol to manage authorization and tokens within the Chromia ecosystem. It represents the fourth version of the Flexible Tokens protocol, with improvements over previous versions (FT1, FT2, FT3). While FT1 was implemented in JavaScript, FT2 in Kotlin, and FT3 in Rell, FT4 is also implemented in Rell with enhancements for better performance and functionality.

FT4 allows you to manage two types of tokens – fungible tokens (like common cryptocurrencies) and non-fungible tokens (unique digital collectibles like NFTs). It even makes creating your own NFTs directly on the Chromia network easy.

One of the critical features of FT4 is its support for cross-chain transfers. This means you can move your tokens between the Chromia network and other blockchain platforms, like Ethereum, expanding the reach of your digital assets

Originals protocol

Non-fungible tokens (NFTs) are unique digital assets widely used for digital art and collectibles. Ethereum's ERC-721 and ERC-1155 non-fungible are the prevailing standards for NFTs. Still, they have limitations, such as high on-chain data storage costs and reliance on centralized services for hosting metadata and images.

Chromia offers a solution by enabling more extensive metadata storage and on-chain storage of NFT image files. This ensures complete decentralization, making NFTs on Chromia self-reliant. While FT4 manages ownership, Originals, a separate asset description protocol, defines the characteristics of those tokens. The protocol's name reflects its primary function: describing original digital objects represented as tokens and fostering an ecosystem for digital ownership and interaction.

The Originals protocol utilizes the Dynamic Instance Protocol (DIP). This highly flexible data storage solution allows you to store a wide range of information about your tokens beyond just artwork. This could include details like the token's minting origin, associated utility, holder rights, and even metadata for tokens originating on other blockchain networks.

Cross-chain communication protocols

Finally, Chromia has developed protocols for seamless cross-chain communication, known as Interchain Messaging Facility (ICMF) and Interchain Confirmation Facility (ICCF). ICMF enables message broadcasting and subscription across different blockchains, while ICCF provides the necessary proof construction and verification, enhancing the interoperability and functionality of the Chromia network.

By combining these robust protocols – FT4 for token management, Originals for asset description, and the cross-chain communication tools – Chromia has created a comprehensive and versatile foundation for secure digital ownership and interaction.
