Not in general, bit for example for Bitcoin it costs at minimum 0.00001 
BTC per kB of transaction [0] (not kB of data). Given current rates 
that's 5 cents.

Other blockchain based systems such as Certificate Transparency logs 
don't have this requirement but one needs to go through trusted CA to 
get their data there.

Still, files have been put in CT logs:
