| Opis: | This dissertation introduces a novel off-chain channel model aimed at enhancing existing solutions to address scalability challenges in blockchain technology. It begins with an overview of the problem statement, research objectives, methodology, and potential limitations before establishing a thesis and hypotheses. A comprehensive theoretical background on blockchain technology, scalability solutions, and the off-chain channel approach ensures a common understanding of the topic. To provide a thorough overview of existing off-chain channel solutions and identify and categorize their limitations, we conducted a systematic literature review, identifying 65 relevant studies. Through detailed analysis, six categories of solutions and six implemented off-chain channel solutions were identified. Five primary categories of limitations were also identified: routing, flexibility, privacy, network properties, and online assumptions, some with sub-limitations. To address these limitations, a new off-chain channel model, named ”Off-chain Channel as a Service,” is proposed, featuring four core design decisions: eliminating the need for an off-chain channel network, assuming blockchain properties by design, introducing a trustworthy service, and enabling flexibility by design. Validation and evaluation of the proposed model employ case-study and experiment research methods to confirm compliance with off-chain channel principles, validate it against identified limitations of existing solutions, analyze its impact on blockchain scalability, and assess its applicability across blockchain platforms. For this purpose, two off-chain payment channel prototype solutions have been implemented, each using a different underlying blockchain platform, namely Ethereum and Solana. Moreover, the proposed model’s security evaluation using risk-analysis methodology is also provided. Qualitative and quantitative analysis demonstrates that the proposed off-chain channel model adheres to off-chain channel principles, improves most identified limitations of existing solutions, positively impacts blockchain scalability, and can be applied to different blockchain platforms supported by smart contracts. |
