MULTIVERS · KeyGen — Unique Key Genesis
Play a game. Generate a cryptographic key. Own it forever.
What it does
MULTIVERS KeyGen is the world's first cryptographic key generator powered by human gameplay entropy. Every move in our hex-board space strategy game — dice rolls, planet conquests, ship battles, wormhole crossings — is captured and fed into SHA-256. The result: a unique 256-bit key that can never be reproduced. Proof of Play protocol. Fully local, zero servers. Protected by INPI eSoleau N° DSO2026021886.

- SASatoshi9000 analog BTC key generator (mechanical)2024 · ▲164
I built this machine so I could generate Bitcoin keys that I could trust. Air-gapped and simple to use and understand (mechanical). The Satoshi 9000 demo: https://youtu.be/bJiOia5PoGE The key value proposition of the machine is that it generates analog randomness in the physical world and converts it into digital (1’s and 0’s) randomness. Seamlessly. But it occurs to me that it may have other uses beyond crypto keys for your own use, such as: * Randomized clinical trials. Clinical trials need a high degree of transparency for ethical reasons; also, for legal reasons should it…

- ATA tiny and platform-agnostic true random number generator for FPGA/ASIC2023 · github.com · ▲27
It is based on phase noise, consumes less than 60 LUT4s/FFs and achieves up to 7.99 bits of entropy per byte. Feel free to comment if you have any questions, ideas or thoughts :)

- DBDouble blind entropy using Drand for verifiably fair randomnessFeb 2026 · blockrand.net · ▲21
The only way to get a trust-less random value is to have it distributed and time-locked three ways, player, server and a future-entropy. In the demo above, the moment you commit (Roll-Dice) a commit with the hash of a player secret is sent to the server and the server accepts that and sends back the hash of its secret back and the "future" drand round number at which the randomness will resolve. The future used in the demo is 10 secs When the reveal happens (after drand's particular round) all the secrets are revealed and the random number is generated using…

- H6Homebrew 6.0.0▲1,481
Today, I’m proud to announce Homebrew 6.0.0. The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!
