¿Qué es Reorganisation (reorg)?
When nodes switch to a different chain with more accumulated work, discarding one or more recently accepted blocks.
Short reorgs of one block happen naturally when two miners find blocks at nearly the same moment; the network converges on whichever chain gets extended first.
Deep reorgs would require enormous sustained hashrate and have not occurred on Bitcoin outside its earliest days. This is the mechanism confirmations protect against.
