Is there an easy way(java or nodejs library) storing data using op_return. I want to store small images(tiles (own file format)). Goal is an online game
thank you very much! I want to store a small bitmap into 220 byte:
2 byte prefix
26 byte meta data(text descr.)
192 byte pic=16x16 pixel and 6 bit color depth
so one can use 64 colors
