Claim 0:
1. A computer-implemented method for configuring a blockchain network, comprising:
initializing, by a delineate node of the blockchain network, pass-through services;
receiving, at the delineate node, a registration request from a device;
validating the device, by the delineate node in response to the registration request, using a physical uncloneable function (PUF) response received from the device, wherein the PUF automatically provides a cryptographic proof for immutable registration key previously measured or calculated by a manufacturer of the IoT device and previously communicated to the delineate node by a secure channel, and wherein the validating comprises:
sending, by the delineate node, a challenge to the device; and
receiving, by the delineate node, the PUF response from the device;

registering, by a processor of the delineate node in response to the validating, the device in a virtual profile; and
performing, by the processor of the delineate node, a pass-through service for the registered device.
