Just saw the "accelerate with gpay" in @mempool. It's quite interesting especially for non-tech people. It would be even better to accelerate by paying via lightning or cashu, maybe using mempool's mint if they run one.

Thought experiment: In 2140, mining will solely rely on transaction fees due to zero block subsidy. This new competition dynamic may result in miners prioritizing valuable blocks over others. For instance, if whales broadcast high-value (and high-fee) transactions at the same time, other miners might attempt to claim those rewards instead of building upon the existing block. Why would they compete for 100m sats when they can get 300m sats? The difficulty would be the same for both. Consequently, this could lead to an increase in short-term chain splits and potential rollbacks for mining the same lucrative transactions. If short-term chain splits become common and depending on fee volatility, rollbacks might extend beyond one block. In such a scenario, would the traditional "six confirmations" rule still provide a perfect guarantee of transaction finality? After writing this, I realized there is a paper on the topic: mining_CCS.pdf #asknostr #bitcoin #mining

Having been in the Bitcoin space, doing legacy online payments stumps me every time. For the equivalent of a zap (we know how easy it is), I have to login to my custodial "wallet" account, which has logged me out for some reason. The login requires a password that I must fetch from my password manager. Then I need to 2fa, so I need to copy and paste the pin. Then I can proceed with the payment, which requires me to login again (now in the web), which sends me another 2fa code (the transaction's 2fa code) that I need to copy and paste. Cards (Visa/Mastercard) are easier but still have their frictions. Not to mention the extremely bad and unsafe pull-based model, in contrast to cash and Bitcoin.

Is #Nostr the ultimate 2fa and the ultimate account creation/validation? Better yet, is Nostr the ultimate identity solution? I set up #Lifpay and the sign-up/login flow was amazing. No email required, no phone number. No username and password. Only npub.

On passwords: who thought that in-app login popups are a good idea, especially when you cannot even see/validate the HTTPS URL? I talk about those "login to google" window inside apps. You just enter your credentials in a box that looks like google but you can't validate. How are those still a thing?

Bitcoin: the internet of money. Nostr: the internet of social networks.
