| Popis: | Blockchain networks have enjoyed remarkable attention the past few years in both the research community and the society at large. Such networks carry the promise of highly decentralized validation and witnessing of important social and economic events, reducing the need to rely on centralized authorities. Public proof-of-work based networks specifically, despite their limitations and challenges, continue to be popular due to their simplicity and intuitiveness. However, for such networks to perpetually meet viability, efficiency, security and environmental sustainability objectives, they need to adapt to environmental changes via continuous reconfiguration of their operating parameters. In this paper, we attempt to formulate this blockchain network adaptability problem as one of control engineering. We sketch the basic characteristics of blockchain networks as systems and identify variables available for designing a controller that allows such networks to attain macroscopic operating objectives. By means of describing and simulating a simple idealized proportional controller, we demonstrate the benefits and some of the challenges in designing such controllers. |
