Neo among chains supported by KardiaChain hybrid blockchain interoperability platform

KardiaChain is an interoperability-focused public blockchain platform, introduced as a hybrid blockchain solution/infrastructure for enterprises and governments. The team intends to expedite the adoption of blockchain and link other blockchains together in a non-invasive manner.

Neo is one of the first public blockchain platforms to be supported by KardiaChain, alongside Ethereum and Tron, with cross-chain activity expected to go live in Q3 2020 as part of the KardiaChain MainNet launch. This is achieved through the use of its dual node solution, which can be applied to facilitate cross-chain communication between public and private blockchains without requiring them to adhere to a specific protocol.

This “non-invasive” design is enabled by grouping together nodes which monitor both KardiaChain and one other target chain. A group of Kardia-Neo “dual nodes” would work together to read, validate, and process cross-chain calls between Neo and Kardia, likewise a Kardia-Ethereum dual node group would do the same for Ethereum transactions.

A video example of a cross-chain transfer between Ethereum and Neo, handled by KardiaChain dual nodes, may be found here.

In the example, an Ethereum deposit is detected by Kardia-ETH dual nodes. A smart contract on Kardia is updated with the transaction, which generates the Neo transaction via the Kardia-Neo dual nodes, who relay the transaction on the Neo blockchain.

Dual nodes are open for operation by anyone. Each node group will perform its own consensus on cross-chain operations, producing “dual blocks” for a group ledger to preserve state. The nodes are incentivized for producing the “dual blocks” of this ledger, and the signatures can be gathered KardiaChain validators for inclusion in blocks of its main ledger. This provides the mechanism to link the two blockchains together.
