Torr, is there a Tiktoc about it that I can watch?

Mochi101: Not that I'm aware of.

I was joking hey.

All about the attention span of many people these days.

I know XD

The best part is seeing how anxious they get when away from social media.

Literally frenetic.

Torr, younger generations... I can't see how they're going to survive.

They'll find a way.

Will have a walk now.

See ya

hey folks, question: how exactly does the network protect from malicious users broadcasting one transaction to one node, while broadcasting another version of that transaction to other nodes? how does that get handled? i know it has something to do with confirmations, but how exactly does that work?

winter: it uses PoW to pick one of these as "canonical".

moneromooo: so is it based off majority - how does that selection work?

The canonical chain is the one with the most cumulative work. And it can include only one of the two txes, or it'd be invalid.

Typically, the first one mined in time is selected, but not always if they're mined close in time.

To be clear, what exactly do you mean by the two txes -- how is one TX shown to be related to another, at least in terms of being added into the chain? How does the network differentiate between a node announcing a legitimate transaction and an illegitimate one, assuming the transactor only announced it to one node?

By "the two txes" I mean the transactions in your question. The rest of what you said I do not understand.

Ask more precise questions.

"a legitimate transaction and an illegitimate one" wrong, both are legitimate

first come, first served

whichever gets mined first will be what's actually spent

what I failed to elaborate on the first time is that why wouldn't both txes get spent?

(if possible based on funds)

because they use the same key image

if they spend the same input

ah, okay, those are some terms i'd have to look into -- thanks

winter the money in every transaction is "held" in something called a key image. Imagine something like a serial number on a $5 US dollar. This key image can only be included in a mined block one time. If a miner attempts to include it a second time in a second block, the network will reject the second block

So if I submit two transactions that reference the same key image, the transaction that becomes spent is the first one mined by a miner that ends up in the longest chain

The longest proof of work chain
