The team created a system called “Twine” that distributes the random number generation process across multiple independent parties, with each step recorded in tamper-proof digital ledgers called hash chains. This means no single organization controls the entire process, and anyone can verify that proper procedures were followed. During a 40-day demonstration, the system successfully generated random numbers in 7,434 of 7,454 attempts – a 99.7% success rate. Each successful run produced 512 random bits with mathematical certainty of randomness bounded by an error rate of 2^-64, an extraordinarily high level of confidence.
I would assume that this would be really good for high-risk security projects, but I’m not sure this if is completely essential for lesser-risk users who want to make a secure password and can already use dice.
Couldn’t you just use a 4k camera pointed at a lava lamp like cloudflare? Lavarand - Wikipedia. They also combined it with a double pendulum and a geiger counter.
I think the goal of the research project was to have a RNG be quantum (so that it is truly random rather than pseudorandom) and, more importantly, verifiable/traceable (so that it’s output is verified to be quantum and untampered with). The lavarand would be neither of those. I’m not a physicist or a cryptologist though, so I can’t speak on how novel this research is. Seems neat though.
If you want to get verifiable entropy for yourself:
Use some dices, favorably casino grade.
If you want to get entropy that can be verified independently, so you want to prove that something is a random choice:
Use the a proof of work Blockchain like Bitcoin or Monero and point to the hashes of future blocks, these are impossible to predict/tamper (Even if you would control the miners, cause the miner just guess the hash and don’t chose them)
