The 4th dimension cannot be time, much like we as humans are unable to see in 0-2, 4-∞ dimensions and by this extension cannot have a 4th dimension within our universe; it is entirely 3rd dimension. Everything is made from 3 dimensional objects called atoms.
The construct of time is purely human, which lends itself to the perception of a beginning and why many people believe in creationism. Without time there will not be a beginning or an ending.
time is the 4th dimension (we notice that in extreme events like merging massive black holes), could be like an orthogonal axe over the set of {x,y,z} valued almost constant in the entire set
a blockchain analogy of time is the ability to forwarding the properties of a system again and again
ooohh lol...bitcoins are pieces of time!!
