About blockchain:
Bitcoin produces a block every 10 minutes on average. After Ethereum transitioned to proof of stake, it produces a block every 12-second slot.
On a proof-of-work chain, rewriting an old block means recalculating all subsequent blocks and catching up with the ever-growing main chain, which is extremely costly.
