In our days, decentralized computing is a marked trend. Beyond its advantages in terms of scalability and fault tolerance, it is better adapted than centralized computation to ethical constraints, including security and privacy preservation. Yet, the autonomy of participants raises the issue of how to motivate them to follow protocols as prescribed. I will sketch an approach based on coutility to make ethical behavior the rational choice of participants. Next, I will describe some applications of this approach to problems in decentralized computing and decentralized machine learning.
