no1s1 is a house that is owned by no one. It is governed by a smart contract and explores new ways of participation with digital tools. One could say that smart contracts are the ultimate open code: They allow the performance of credible transactions without third parties. These transactions are trackable and irreversible. Smart contracts are transparent, immutable and can be made partially or fully self-executing, self-enforcing, or both. This provides us with new opportunities and threats to the society of the future. no1s1 is a pilot to explore these new possibilities and discuss them with a broader audience.
