Abstract: Data security is a significant concern for any modern-day network deployment. Blockchain resolves security issues up to a large extent. Blockchains are nowadays widely accepted for secure transactions and network communications. Since there is no limitation on the amount of data being stored, blockchain-based networks tend to become slow as the length of principal blockchain increases. To overcome this issue, the concept of sidechain is introduced. With sidechains, blockchain systems become faster and inherit blockchain characteristics, including security, transparency, and traceability. This paper proposes a solution for creating context-aware sidechains to increase system performance using a heuristic approach. The proposed algorithm assists in creating customised sidechains via optimisation of blockchain mining delay using stochastic modelling. It generates many stochastic sidechain combinations, evaluates them based on mining delay, and selects optimal configuration. The proposed model is evaluated on different network conditions by varying network size and traffic density.

Keywords: blockchain; sidechain; data sharing; fitness; quality of service; QoS; delay; energy; computation.
