- 🧵 Could Bitchat have 5x the range and 100x the throughput for the same power expenditure? I explored how Wi-Fi Aware could improve the reliability and throughput of Bitchat and mobile ad-hoc networks in the absence of internet connectivity. #bitchat 👇
- 1/ Bitchat today uses a BLE mesh for ad-hoc messaging without internet access. BLE is ubiquitous and low-power, but its short range (≈10–30 m) and low throughput can limit the real-world reliability and coverage of offline mobile ad-hoc networks that depend on it.
- 2/ Wi-Fi Aware is a wireless discovery and mobile p2p networking standard long-supported on Android (2017) and newly supported on iOS (2025). It lets devices efficiently find each other and set up high-bandwidth Wi-Fi links without an access point.

- 1/ Had a great time on the ZK podcast chatting about local-first and emerging use cases for programmable cryptography (ZK, HE, MPC) with @goblinoats.com @arro.bsky.social @nicomnbl.bsky.social . I'm excited for more exploration here & I'd love to hear ideas from both local-first & prog crypto worlds
- The ZK Podcast released an episode on local-first software this week! @arro.bsky.social and @nicomnbl.bsky.social chat w @grjte.sh & @goblinoats.com about the foundations of local-first architecture, CRDTs and how ZK can be incorporated into these models. zeroknowledge.fm/podcast/367/
- 2/ Particular thanks to @expede.wtf @patternist.xyz for helpful discussions beforehand and @inkandswitch.com @martin.kleppmann.com @jakelazaroff.com @jessmart.in for referenced work For an intro to the idea of "programmable cryptography" see gubsheep's excellent essay: 0xparc.org/blog/program...
- Reposted by grjte📝 new blog post! i spent a while looking into homomorphically encrypted CRDTs. spoiler alert: they don’t work super well! (but you should still check it out — i break down what homomorphic encryption is and how it works, and there are lots of explorable explanations along the way!)

- Reposted by grjteI've been working on a network-local ATProtocol dev environment that gives me end-to-end production functionality for Smoke Signal, including handle resolution and repository access. Here’s how I put it together. 🧵
