Ontology, a high-performance public blockchain project, and a distributed trust collaboration platform, recently released its design for a lightweight and safe multichain system and cross-chain solution.
The solution uses the Ontology blockchain as the main chain, and supports both side-chains whose architecture is the same as the Ontology main chain and side-chains whose architecture is different from the Ontology main chain.
The design allows for interaction between the main chain and side-chains, and also between side-chains. The main chain manages side-chains using a multichain management contract, and the cross-chain interaction between source chain and target chain is done through a cross-chain management contract.
The proof of cross-chain interaction is done through synchronizing key block headers and other state information.
Those interested to read more, can find the full Ontology multichain design paper on GitHub.
Last year, Ontology set up the research institute in order to focus more on the research and development of core blockchain technology and strengthen the ability to explore, reflect on, and apply emerging technologies, as well make contributions to the entire industry. At present, there is more than 10 R&D personnel in the Ontology Research Institute.
