ConnectionChain: Secure Interworking of Blockchains
This addresses the problem of secure interworking between blockchains for applications requiring integrated ledger operations, but it appears incremental as it builds on existing Smart Contract technology.
The paper tackled the limitation of traditional Smart Contracts in handling tightly related blockchain ledgers for business logic by proposing ConnectionChain, a method to extend Smart Contract functionality, and introduced a prototype system.
Blockchain is a core technology to manage the value of cryptocurrencies, or to record trails of important business trades. The Smart Contract on blockchain is expected to improve security on blockchain system with automated operation, but it cannot be the solution when the application service required to operate tightly related blockchain ledgers as service business logic. This paper proposed the method to extend the functionality of traditional Smart Contract on blockchain, and introduced the prototype system, named 'ConnectionChain'.
