Today I want to talk about Blurhash.
The idea is quite simple: an image can be “shrunk” to a particular hash represented as a short string. From this string, you can generate a blurred image that remotely resembles the original. Such a blurred image can be used as a muffler while the main image is loading or to hide the main image for other reasons (paid and/or adult content).

I experimented a bit with a Go library and made a CLI for it: https://github.com/chuhlomin/go-blurhash-experiment
