Y'all saw me build Mario Kart: Double Sats in public and take it to events globally. I've been met with an overwhelmingly positive response, and now I need your support. Asking for help is always vulnerable and scary, but if my work has inspired you, let's team up to push education forward! 🍄 Please consider supporting me in bringing joy, knowledge, and of course bitcoin to the people who need it the most! ⚡🌍 🔗 Donate:

Earnest question: If we adopt BIP177 (which I already have) and start expressing sats as integers with the ₿ symbol on the left, what’s the best way to handle millisats? Showing them like ₿0.001 feels too confusing right now. Any ideas?

I have upgraded Mario Kart: Double Sats to reflect the changes outlined in BIP 177. 🫡

i think we should rename sats to bitcoin and bitcoin to mega bitcoin (i am serious)

i really love jq (for json)

It’s rad/mystical to me how Zeus allows for circular payments but lncli does not. I love it @ZEUS 😍

My jaw dropped View quoted note →

Sometimes I wish I was a raver. It seems like such a fun subculture. And the people seem extra friendly. But I do not like the music. 🤔

Why I'm for loosening the OP_RETURN limits ⏎ - In practice, OP_RETURN is already unconstrained: see Carman's OP_RETURN bot or Portland's Slipstream. - Encoding arbitrary data via OP_RETURN is far more responsible than doing so in witness data, as it's 4x more costly. - OP_RETURNs are prunable and do not pollute the UTXO set, making them vastly preferable to faux outputs that burden every node indefinitely. - Mining non-standard transactions that bypass mempools undermines decentralized transaction propagation, disrupts fee estimation, and increases block propagation latency (especially when compact block construction fails due to missing transactions). - This latency disproportionately impacts smaller miners and encourages direct submission to large, well-connected players, widening the profitability gap and increasing centralization. - Layer 2 protocols are especially sensitive to fee miscalculations, making transparent and measurable fee behavior essential to their reliability. While I share the distaste many have expressed toward tokens, inscriptions, and BitVM (when used as a casino), I care deeply about minimizing harm to bitcoin’s base layer. Allowing larger, standardized OP_RETURNs is a pragmatic step in that direction.

I regret to inform you all that moving forward I have reduced my Damus default (non-custodial) zap amount from 1,337 to 21 sats per zap. ⚡️

Mario Kart: Double Sats was a success at the grand opening of the Tokyo Bitcoin Base 🍄

Stickers for the Tokyo premier. Sorry I couldn't fit my whole npub on there. Who's going to come play?! 🍄

MARIO KART: DOUBLE SATS!! 🍄 I'm premiering my latest Lightning game at the Lightning Fair at the new Tokyo Bitcoin Base on April 26th, and I'd love to see you there! Compete against other Mario and Lightning lovers to win sats streamed in real-time. ⚡️

Update: Okay. Mario Kart: Double Sats now streams you sats in real time for every second you're in first place. This may be the coolest thing I've ever seen. 😭 Thoughts: - Writing Python is so easy, it feels like cheating - I don't vibe code—writing out every line is too much fun (plus, vibe coding can cause issues later...? Also, AI can't fully figure out stuff like making this game yet) - Sending glitches to the game over Lightning (like I did with Super Mario Sats) I have not figured out yet, and I'm not sure how practical it will be - Who wants to play this with me?! In person first before I put it online
