  Internet of quantum blockchains (IoB) will be the future Internet. In this
paper, we make two new contributions to IoB: developing a block based quantum
channel networking technology to handle its security modeling in face of the
quantum supremacy and establishing IoB based FinTech platform model with
dynamic pricing for stable digital currency. The interaction between our new
contributions is also addressed. In doing so, we establish a generalized IoB
security model by quantum channel networking in terms of both time and space
quantum entanglements with quantum key distribution (QKD). Our IoB can interact
with general structured things (e.g., supply chain systems) having online
trading and payment capability via stable digital currency and can handle
vector-valued data streams requiring synchronized services. Thus, within our
designed QKD, a generalized random number generator for private and public keys
is proposed by a mixed zero-sum and non-zero-sum resource-competition pricing
policy. The effectiveness of this policy is justified by diffusion modeling
with approximation theory and numerical implementations.
