“any two willing parties”§1 · Introduction · Satoshi Nakamoto · 2008 · Read in context ↗Bitcoin design context
Section 1 connects direct exchange with avoiding mediation costs that constrain small payments.
The passages below are our reflections, not statements of religious belief by Satoshi Nakamoto.
Our understanding
Voluntariness matters beyond the first agreement. Conditions, capacities and goals change. Respectful cooperation permits someone to express a wish to stop without treating every change as betrayal. Choosing to remain is different from having no realistic way to leave.
Exit does not erase obligations already undertaken. Ending future work, completing agreed tasks and handling costs already incurred are distinct questions. Clear boundaries protect both the person leaving and those who relied on a promise. Refusing new demands is not the same as evading existing responsibilities.
Communities can substitute belonging for explicit terms. We want participants to question, disagree and withdraw without purchasing loyalty through donations or public declarations. Relationships should draw strength from continuing voluntary commitment, not humiliation or unrelated penalties imposed on departure.
Bitcoin offers a concrete example of this autonomy: an operator can reject a block on their own node, but local rejection is not a veto over the network and does not by itself establish a violation of shared rules. Others retain their own judgment. Running a validating node and contributing computing power to build blocks are different roles; local choices are not equal-weight votes over the whole network.
Proof of work expresses support for an accepted history through actual computational work, rather than allocating rights according to money spent in the past. Participants face ongoing costs, opportunity costs and possible losses; historical expenditure grants no additional voting weight by itself. We therefore emphasize bearing the consequences of choices through action, rather than treating sunk costs as proof of correctness. Investment can show commitment without purchasing obedience.
Ideas in everyday life
A volunteer who leaves can hand over agreed tasks and entrusted information. A clear handover protects shared work without becoming an indefinite barrier to departure. Identify remaining obligations and their limits rather than treating every request as binding.
Reflection in practice
Are entry, refusal of additional demands and exit equally understandable? Which existing responsibilities still need to be handled after leaving?
