According to Cointelegraph, Max Raskin and Jack Millman, professors at New York University School of Law, recently published a paper in the Journal of Emerging Technologies discussing the legality of using blockchain-based smart contracts for "personal growth bets." A personal growth bet refers to a unilateral contract that a person signs with himself, usually for self-improvement, such as starting or stopping a certain behavior within a specified time. The researchers believe that incentives can have a positive impact on individuals' successful completion of difficult personal tasks. However, without accountability, such incentives are unlikely to work. The authors believe that smart contracts can act as executors and supervisors, allowing an ambitious person to effectively constrain his future behavior without involving others.
