Sats4Files: Decentralized File Hosting based on Lightning

Sats4Files is a protocol for decentralized file hosting. It allows users to request data from untrusted servers, and upon receiving the encrypted data, they can pay for the decryption key via Lightning. The exchange is atomic, ensuring that the user only receives the data if they pay for it, and the seller only gets paid if they deliver the data. The protocol is an efficient form of verifiable encryption, which is similar to verifiable secret sharing using Shamir's algorithm.

This scheme is simplified and does not fully solve the problem, as discussed in the Limitations section. This writeup intends to spark interest to solve the remaining issues beyond the fixes that we suggest.

Sats4Files Problem

The client wants to buy from the server the file corresponding to a particular file_id.

Here, we assume we have PTLCs on Lightning instead of HTLCs. That means we can buy a discrete logarithm over Li

Generative Geometry in Browser + Node.js

Here is a script that can be run with canvas-sketch to generate OBJ files from a parametric/algorithmic 3D ThreeJS geometry.

Hitting "Cmd + S" from the canvas-sketch tool will export a PNG and OBJ file of the scene.

If the same script is run from Node, it will simply render the OBJ to stdout, or write to the filename argument if given.

Don't use VPN services.

No, seriously, don't. You're probably reading this because you've asked what VPN service to use, and this is the answer.

Note: The content in this post does not apply to using VPN for their intended purpose; that is, as a virtual private (internal) network. It only applies to using it as a glorified proxy, which is what every third-party "VPN provider" does.

• There's also this article about VPN services, which is honestly better written (and has more cat pictures!) than my article.
