Require a reasonable miner fee to accept zero conf and they'll have less than a second to try their double spend.
You mean like the 1sat/byte everyone here keeps touting? Or are you advocating we pay 10+ sat/byte to uphold the zero-conf narrative?
Seriously, describe to me how you'd steal a coffee with a doublespend and why it'd be worth it to even try. Spell out the economics and odds of success.
Except WHOOPS now there's a mug shot of the dude stealing and an immutable record of his theft AND the miner who aided him. Pool operators start bouncing that guys blocks for sport??
exactly.
Reputation will start to have weight moreso than ever when tokens come in too.
This whole double spend argument is a distraction.
Like say I bought a $100 microwave with 0-conf and got lucky enough to make it out of the store and double spend the $100 - the store will then send my mugshot to the local police.
I mean you can get it to confirm on the blockchain. That's not really what I'm getting at. I'm wondering how someone would steal merchandise of sufficient value to justify the effort.
If the merchant requires a good miner fee to make sure the txn propagates quickly and gets "first seen" there's minuscule chance you'll get lucky unless you collude with a miner.
@memo was citing an article about the "how" today, let me see.
Same way they're doing it now. Best case it works and I get free coffee. Worst case it doesn't. If you had a 10%+ chance of getting free stuff wouldn't you take it?
What kind nd of free stuff? If I didn’t like it I wouldn’t take it. Now if it’s from Tiffany Chanel Dior I would take it in a heartbeat. Unless it was stolen or fake of course
10+ sat uphold. That is a great incentive for miners to move faster then the next guy. 1 sat equates same, faster miners move faster transactions and more money they acquire.
Enough that it's above the threshold most miners have set for their mempool yeah. 1sat/byte is enough for now but it'll be a moving target as activity ramps up.
The only way that it will become a arms race is if the blocks starts to get filled, and the plan is to raise the block size if and when that happens.
Right! The way to make 0-conf safe is raise the block size! Miners automatically find the fastest way to propagate txns because they're keeping an eagle eye out for incoming blocks.
