Random.org is a website that provides true random number generation (TRNG) services, which means that it generates random numbers that are not predictable or biased. The website was created in 1998 by Dr. Mads Haahr, a computer science researcher at Trinity College Dublin, as a research project to investigate the potential of using the internet to generate random numbers.
Random.org uses atmospheric noise as a source of randomness to generate its random numbers. This is done by using a hardware random number generator that captures atmospheric noise from radios tuned between stations, amplifies it, and digitizes it to create a random bit stream. The random bit stream is then used to generate random numbers, which can be used for various purposes such as lottery drawings, simulations, and cryptography.
In addition to its random number generation service, Random.org also provides other services such as random image generation, coin flipping, and dice rolling.
The website’s random number generation service has gained a reputation for providing high-quality, unbiased randomization services, and is used by various organizations for the random selection of winners in contests and lotteries, such as the World Cup ticket lottery and the Olympic Games ticket lottery. Flipsies.io uses Random.org to ensure true randomness in a provable way.
