{{ The Technologies That Remove Each Other’s Constraints }}

The stack has 6 layers. Read them top-down as demand (each layer requires the next), and read them bottom-up as foundational (each layer allows and is required for the next). 

Decentralization is not its own layer; Decentralization is a design choice at EVERY LAYER:  Who owns the machines? Who owns the data? Who generates the power? Who owns the factory, the ledger, and the models? 

Treat decentralization as interesting when it releases a binding constraint such as latency, interconnection, payments, accountability, permission to operate, and resilience to attack. 

Decentralization shows up in every layer in important ways that accelerate the whole stack.

LayerTechnologiesContraints
DemandAI models, Agents, Software and Hardware that takes actionTask reliability, permissions, and the risk of being wrong or losing control in physical or financial environments. Not model parameter counts. 
CoordinationPayments, identity, privacy, settlement, policy, provenance, tracking and accountabilityWhether regulatory bodies, custodians, providers and users themselves will accept a machine as a counterparty.
ActionRobotics, industrial systems, manufacturingData access, data movement, learning by watching, power, latency, safety, long tail maintenance for bespoke or small batch parts.
InfrastructureRaw materials, chips, data centers, blockchain nodesLand/location, water/cooling, social acceptance, transformers, copper, rare earths, silver, gold, skilled trades.
FuelGas (now), Nuclear (Fission - next), Fusion (later)Time-to-first-electron, transport/connection, fuel cycles, regulatory requirements, social acceptance.
Time-RiskQuantum computing and advanced AI modelsProliferation of hacking networks (now), quantum applications (2030s), Elliptic Curve Cryptography breaking (2029-2035)

Each technology in the stack can remove the constraints of others, allowing auto-catalytic mutual acceleration in capabilities and commercial viability.
