That is an interesting comparison - human beings and the blockchain. We are all nodes! Very interesting idea.

I often compare humans in a similar way. Humans remind me of the brain. Each individual is like a neuron (brain cell) and it holds onto information. It also connects to other neurons (humans) and transmits that information. Humans form networks and pathways of information and together create a sort of larger consciousness around the planet. If consciousness is the overall waves found within the brain, that are created when ideas/thoughts/beliefs and information are transmitted among the individual neurons, then perhaps the earth is conscious. The same process of information transmission, that takes place in the brain, also occurs throughout the planets living biosphere.

As you said, we are a microcosm within a macrocosm! If god is the whole and we are a part of the whole, then we are a part of god. Together we are all god.
