Total Commit and Transaction Off-Chains (TCTOC): A Blockchain Scalability Solution

As an evolving technology, blockchain has found its way into multiple fields such as finance and trade and is set for integration in many fields today. It is limited though, by how poorly it performs when network size scales. Poor blockchain performance when experiencing network growth is manifested as a trilemma; transaction throughput, network storage demands and network data propagation. In this paper, existing literature with proposed solutions for the scalability trilemma is identified and analyzed to bring forth a new possible solution. Total Commit and Transaction Off-chains (TCTOC) is proposed as a synthesis of two solutions in the literature: 1) node committees for improved computation, and 2) off-chain transaction channels for improved transaction management. The feasibility of TCTOC is confirmed using the works that constitute the synthesis.
