In Bitcoin nodes follow the chain with the most amount of work. That is not necessarily the "longest" chain. You can use a single ASIC to mine the longest chain probably in less than an hour (by manipulating the timestamps, etc.) at difficulty 1 from the genesis block but it won't have the "most amount of work" hence it will not be followed.
If you want to "re-write" history, you need to have most hashrate to perform the most work (14+ years worth of work) which is obviously impossible.
14+ years "worth" of work....?
oh......... can't you see what I meant?
If you take TODAY's hardware and put them to work BACK....
from start.....
and ADD all that new work
I didn't do the math, but i expect it's still too expensive for at least 99.9% human.
* Bitcoin Core currently has several checkpoints for blocks it expects in the current chain. The last checkpoint is from 2022, so if you want to fool the latest Bitcoin Core, you have to start your work from that point.
Such feature no longer exist, see
