How double spending 1000 low-value Bitcoin transactions instead of a few high-value transactions can give an attacker a higher chance of success.

@harding Thanks! Good points, especially (2) might turn out really significant. I'll update the article tonight.

I haven't heard much about this kind of attack. Have you seen anything on this elsewhere?

1,000 Lego sets attack

I explain and contemplate a double spending attack that targets many low-value transactions instead of few high-value transactions.

I'm prepared to stand corrected.

@michaelfolkson How does this work? The link redirects to mastodon.social. Why is that?

@FreePietje Thanks a lot for the info. I'm thinking of upgrading to stable anyway, so that's not a big deal.

@FreePietje I'm on debian 9 currently, so not default on my machine.

@FreePietje ok, I know it's been around for several years, but I just wasn't aware of it until today. Thanks for input.

It's been a few years since I last fiddled with iptables. Now there's a new kid on the block:

nftables

Should I switch? Will I regret trying? I'm only doing basic stuff like NAT and port forwarding.
