it's getting more and more frustrating to create your own full node.
You've been here since 2011. All you need to do is download 1-2 GB per week to keep your blockchain up to date.
So I was wondering: could there be an "Armageddon", with the Status Quo of all addresses and their balances in a special (oversized) block that serves as a new Genesis block?
You can create your own Bitcoin Core Fork that does exactly this, but I don't think many people are going to run it.
It could also "flatten" addresses, and consolidate all inputs to remove dust.
In this case your blocks will be incompatible with the rest of the world.
I think you're missing the point of a blockchain: "a
chain of
blocks". If you don't want to download all of it, just use Electrum. If you want to verify everything, just sync Bitcoin Core from the very first block ever. Why would you want to
trust someone just so you can avoid downloading and verifying 700 GB of data? If I wanted to trust people, I'd use an ETF.
