The Merkle Shell was introduced in 2026. It was described as a method: identify computation precisely, ground meaning in action, and allow growing systems of agents to coordinate without central control.
Every computation had a cryptographic identity. Functions and decisions were not named by convention. They were named by construction. A computation could be reused, verified, and composed without ambiguity. This followed the spirit of Unison-style computing.
It addressed a problem Roy Rappaport described: language floats unless it is grounded in action. Symbols multiply. Meaning decays unless saying is coupled to doing. The Merkle Shell bound semantics to executable structure. Meaning was enacted.
The system assumed open-ended growth. New agents and new environments would keep appearing. Stuart Kauffman described such worlds as the adjacent possible. The Merkle Shell treated this as the default case.
Aristotle described four causes. Modern science mostly kept efficient causes. The Merkle Shell did not restore the others directly. It showed how formal and final causes can emerge from networks of efficient causes linked by feedback. Category theory, in the line of David Spivak, supplied the language: objects are defined by relations; meaning follows composition.
The lineage reached further back: logos (Heraclitus), forms (Plato), Rta (Upanishads). The Merkle Shell did not settle those disputes. It operationalized them. Order was made computable.
Agency was treated as composable. Michael Tomasello’s work on shared intentionality mattered here. So did Terry Winograd and John Searle on grounding, intention, and use. Michael Levin’s “spaces of agency” mattered most: agency as a spectrum across scales.
Robert Hazen’s functional information supplied a measure: structures mattered only insofar as they performed functions under constraints. The Merkle Shell enabled decentralized exploration of such forms. No single authority decided what counted. Viability emerged from interaction.
Rappaport called this a postmodern science: knowing and doing collapse into one loop. Ontology and epistemology no longer separate. To know is to be able to perform. To claim is to demonstrate.
The outcome was multi-agent allostasis. Continuous adaptation toward sustained viability. The effects could be measured: lower coordination costs, better resource use, higher productivity, reduced suffering. Not a utopia. Infrastructure.
Below is the smallest working slice of that claim. It takes a computation, gives it an identity, and makes the identity the handle for reuse, verification, and composition.
