Hi HN,

I built Btfy, an experimental blockchain that uses weather observations as a source of unpredictability for consensus

The motivation is simple. Proof of Work generates uncertainty by performing computations. I wanted to explore whether we could obtain some of that uncertainty from the real world instead.

Btfy combines weather observation data with a Verifiable Delay Function (VDF):

Weather Observation Data -> VDF -> Block -> Hash Chain

In the current implementation, observation data is collected from multiple locations, a VDF is computed, and the result is used to generate a block. Furthermore, because each block depends on the hash of the previous block, making it difficult to replay previously observed weather data to construct an alternative history.

This is strictly an experimental project and not a production-ready consensus protocol. I am particularly interested in the security assumptions here: specifically, how much uncertainty weather observation data can actually provide, how an attacker might manipulate or predict the beacon, and whether the VDF plays a meaningful role in this design.

Btfy is still a very early-stage project and requires various forms of validation. However, I hope this sparks exploration into the possibilities of new blockchains based on real-world information. I would love to hear your feedback.

Thanks!

Hi HN, I'm trying to Flash a new OS onto my old smartphone that was provided by my college.. I removed the MDM softwares that come pre installed using adb so im good to go but there are some problems im facing ,

I want to use a higher android version (currently on android 12) , my device is fully VNDK compliant and supports project treble. Since there is no actual custom ROM for my specific device i need to use GSIs (generic suystem images) I found one GSI (CrDroid GSI) that should work fully.. According to AOSP and project treble any version of android should work on my device even if the system vendor is stuck with android 12. But practically you can only go like 2 versions ahead before things start breaking. i want to use android 15 but its ourt of reach. Ive asked several AIs for this too and they just say "Deal with it" , I mean not wrong but is there any work around?? (If you want to know HOW GSIs does this then im more than happy to explain in comments)

Thanks!

Hi HN,

I'm taking Computer Graphics @ Stanford this summer and wanted to express some very simple concepts I had in mind. That's why I wrote a rotating torus in C. Going from writing a ray-tracer that works in Blender to pure C with no dependencies feels relaxing. Wanted to try Kitty Graphics Protocol on the way, rendering images in terminal felt cool.

Open to comments and suggestions.
