  We describe MaGPoS, a novel consensus mechanism which is well suited to
decentralized blockchain based protocols. MaGPoS is based on a combination of
the well known physics of nano-scale magnetism, and previous implementations of
proof of stake. This system has been studied by hundreds of thousands of
scientists worldwide for over a hundred years, giving it an extreme level of
reliability that is needed for a consensus mechanism. We start by explaining
the physics, and study the properties that make it particularly beneficial for
use in a consensus mechanism. We then show how to apply the physical model to a
decentralized network of nodes, each with their own copy of a blockchain. After
this, we describe some example calculations that a node in the decentralized
network would make, and provide pseudo code for implementation. Finally, we
discuss the how the model achieves all of the important properties that one
expects of a consensus mechanism.
