Hello guys
so the question just like the title?

just why?
isn’t those feature feels making things slower? since it’s mean that we wait 10++ minutes to wait it, i last time waiting it for 32~ min
can’t they just remove lock 10 confirmation so we can trade more?

It’s because confirmation is probabilistic. Ten confirmations is a number chosen arbitrarily. The miners are competing to create the next block with more proof-of-work. By waiting ten (or more) confirmations, a clear winner will emerge (and competing forks will be abandoned). The blockchain with the most proof-of-work is considered the legitimate one.

isn’t 2 confirmation is more than enough? i never seen my own transaction getting rejected or fooled like other coin. if they already 2 confirmation from random blockchain, it normally always good to go…

MUST WAIT 10 confirmation i think make everything “slow” since we had gap around 10-20min

Monero was hit by a “51% attack” before. The longer the wait time, the harder it is to pull off a “51% attack”. This is the choice that developers face:

  • less confirmations (2), easier to hit with an “51% attack”
  • more confirmations (10), harder to hit with an “51% attack”

ahhhh i see, now i understand,
not aware at all about past 51% attack,
btw does we now know how much node out there that host monero? or something like that suppose to be hidden?

The nodes communicate with each other, so it’s possible to have a faint idea of how many nodes are there. But they also communicate through proxies, hiding their true identities.

isn’t you think at 2025 now it’s harder to do 51% attack again?
i mean coin like litecoin they even had 1-2 confirmation check, i really sure the number of node of monero is “almost” there compared to litecoin right?
