Make it real

Ideas are cheap. Make a prototype, sketch a CLI session, draw a wireframe. Discuss around concrete examples, not hand-waving abstractions. Don't say you did something, provide a URL that proves it.

Ship it

Nothing is real until it's being used by a real user. This doesn't mean you make a prototype in the morning and blog about it in the evening. It means you find one person you believe your product will help and try to get them to use it.

Do it with style

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

The final result: require() any module on npm in your browser console with browserify

This article is written to explain how the above gif works in the chrome (and other) browser consoles. A quick disclaimer: this whole thing is a huge hack, it shouldn't be used for anything seriously, and there are probably much better ways of accomplishing the same.

Update: There are much better ways of accomplishing the same, and the script has been updated to use a much simpler method pulling directly from browserify-cdn. See this thread for details: mathisonian/requirify#5

Proposal for a lightweight, database-less, general purpose, name-based file management app

First draft, Easter Sunday 2014

In line with current trends toward lean and simple software solutions reviving and repurposing long-established standards (open plain text vs proprietary rich text formats; file-based static site generators vs bloated database-driven CMSs), the present proposal inquires into a method (and its application) to device a lightweight, general-purpose solution for small-scale digital asset management.

No database is to be used, there shall be no external dependencies, all information carriers should be self-containing, and everything would be file-based. The software would build on a (yet to be established) convention of file naming, which would store metadata for arbitrary files inside the file name, advancing its portability across platforms.

Put as a — somewhat far-fetched — YC-style one-liner pitch: this proposal is about *
