I was wondering about this. What if the universe is like a blockchain, and things don't really happen until they have been confirmed somehow and then everything builds up on top of itself and one event bring us to the another?
The core would be the big bang (capital B blockchain, bitcoin's blockchain) then sidechains would form around this core.
Maybe other universes exists and are like hard forked core's.
Quantum particles that are temporarily in 2 places until an observer observes it or something, would be like the offchain LN transactions, then they get confirmed and the information goes on the main blockchain.
No i didn't smoke anything.
Technically
TIME is the BlockChain.
The Transactions in each Block , is the Current State of reality.

Funny thing , in the Future they study how Blockchains Forked as a comparison , of the effects that a time traveler has when going into the past.
The ripple effect the traveler causes, is similar to the coin age calculation of Proof of Stake.

Merged Mining is used to study similarities to Parallel universes.
(Standard College courses on it , in ~ 30 years or so.)

In time travel, the traveler going into the past is always the cause of the divergence that causes a fork.
If the effects of the fork diverge too greatly from the previous chain of events, then the time traveler wipes out his reality, and the new chain takes over.
So yes, if you kill your grandfather in the past , your future self is never born.
Also the further you go back in time travel , is comparable to the increased difficulty of performing a history rewrite of a blockchain.
The time traveler needing an ever increasing amount of energy to match the temporal resistance, and the blockchain requiring an ever increasing difficulty to be overcome.
