The growth of the distributed ledger space has led to the emergence of multiple blockchains which do not communicate with each other and are operating in isolation. These blockchains are gaining popularity because of features they offer to the applications like network effects, speed, transaction cost, security, consensus algorithms etc. However, these blockchains are operating in silos and are running their ecosystems in isolation from the ecosystems operating on other blockchains. Even worse, the current solutions which are only limited to providing cross-chain bridges are highly centralised and susceptible to counterparty & security risks. There is a pressing need for interoperability between the current blockchains in use. The current growth of the blockchain ecosystem is not being limited by the capabilities of blockchains but by a lack of reliable solutions to connect them. A protocol to allow blockchains to interact with each other will enable decentralised applications to tap into the capabilities of multiple blockchains. Moreover, opening communication across blockchains will usher a new wave of technological advancements in the interoperable defi applications where money markets can operate across chains. Ocelli Chain Network solves the interoperability problem between multiple smart chains using a secure oracle network for inter-chain communication. Ocelli Chain Network facilitates the transfer of information between blockchains allowing applications to both tap into the information from other blockchains and update the information on the other blockchains. This 2-way interchain communication opens up the applications to build innumerable use cases and capabilities in decentralised applications.
