Cardano Cross-Chain Report
Author: Emir Olgun
Date: 18 October 2023
Introduction
We in the littlefish Foundation have conducted one of the most comprehensive researches about Cross-Chain capabilities in Cardano blockchain. This report will present What is Cross-Chain, Cross-Chain Concepts, and Cross-Chain Services that are currently operational and ongoing projects.
What is Cross-Chain
Cross-chain refers to the interoperability between different blockchain networks, allowing assets and data to be transferred seamlessly from one blockchain to another. This is crucial for enhancing the utility and scalability of blockchain applications. Various technologies like atomic swaps, oracles, sidechains, and blockchain bridges facilitate cross-chain transactions. The goal is to create a more interconnected and efficient ecosystem, where one is not limited by the capabilities or assets and services of a single blockchain. For some of these concepts we have written documents as they are complex technologies.
Atomic Swaps and Atomic Swap on Cardano
Cross-Chain Services on Cardano
We also have done research on all the Cardano cross-chain tools we found. Some of these projects are ready to be used, some are still in development and one tool called Microchains was functional but is dead.
Cross-Chain Bridges
These are the operational cross-chain bridges on Cardano:
Here are cross-chain bridges that are not operational:
Cardano Oracles
Here are the operational Cardano oracles:
Here are projects that announced they are working on Cardano but not yet deployed an oracle:
Sidechains
Writers Remarks
As of October 2023, there are not many services for Cardano cross-chain but with new services expected to come online, it looks promising. There are currently couple of available cross-chain bridges, one oracle, one atomic swap, and one expected sidechain. Even though the only oracle solution on Cardano, Charli3, does not offer much services, it has a strong and promising technical infrastructure and it definately has the potential to become dominant oracle service for Cardano.
