YEAH, let's have 8MB block so that way only miners will run full nodes since it will be almost impossible for normal people run a full node in a normal dektop.
Let's give all the power and decentralization to miners cause they know what's best for the whole community
This is a lie Core has pushed on you.
Nope. Bitcoin nodes must work in byzantine environments -
https://iancoleman.github.io/blocksize/#block-size=8Down: 0.447
Up: 3.132
This will be too much for many regions around the world.
Additionally, 8MB blocks are going to need a ton of RAM for that UTXO set . 4MB of Ram isn't going to cut it
Additionally, mining centralization will be far worse due to block propagation latency.
