Whatever is stored in the blockchain is immutable which means I can fetch this data back in the future. As of today (2016-feb),
How does one store a 1kb, 10kb, or 100kb or arbitary data/text in the ethereum blockchain? What is the code needed to do this?
Once stored how do you download the data back onto your desktop?
How much would this cost exactly in ether/gas/fiat at todays prices?
