Today is my son Nash's "Take Your Child to Work Day" so we're learning all about entrepreneurship, blockchain tech, XMTP, and more. In learning about blockchains, we minted some NFTs together, inspired by his idea for a time machine. Go collect them all—they're free! https://frames.neynar.com/f/956a1bf9/e44f6cc4

Houndstooth Coffee is a short walk from the conference center and is really, really solid. Tasty coffee, and consistent. Good for meetings too.

You could! My preference in order is all about sequencing, volume, heat retention. Cortado is small, cools faster, and is quicker to make. That means I can usually enjoy one while the pour over is made. I also get to enjoy it while it’s at its optimum temp.

Oh man. The coffee is pretty good but that breakfast sandwich is god-level good.

Tip for anyone attending ETHDenver: Do yourself a favor and go spend some time at Little Owl Coffee. Get a cortado for sipping, and a pour over to take away. It’s really, really good.

The best part of this is that it's seamless to the user—just subscribe, sign, and see the messages flow in. But behind the scenes, their inbox is doing the work to validate the subscription sender's allowance, and still protecting them from unsolicited senders.

XIP-43 introduces a permission proof—a simple message signed by the user upon subscribing. That proof is then "attached" to the publisher's invite message, which is immediately sent, and can later be read by the subscriber's XMTP inbox app, using the proof to automatically allow the publisher's messages. 🚀

While it would have been ideal to have a "Subscribe with XMTP" button that toggled the publisher to "allow" with one-click, security implications made that a no-go. So a new solution needed to be designed—one that doesn't require a user to sign into their XMTP account directly on the publisher's site.

Last week /xmtp got network-level allow/block prefs, which are shared between client apps. So how can opt-in senders (e.g. subscriptions, newsletters, notifs) skip request filters now? That's where a new XIP (permission preference proofs) comes in: https://community.xmtp.org/t/xip-43-permission-preference-proofs/552

Appreciate the feedback there! Not something that I was aware of. Already kicked off two other independent subs this morning, and will keep doing that to drop Trade.
