It can be interesting to use blockchain technology in our movement for transparency purposes.
... Not really. At best you end up with a less efficient version of a downloadable database....
Less efficient unless a government authority is attempting to censor.
After advocating all this year for the Turkish Wikipedia on IPFS, I very recently learned that it has been a success for a year now:
https://ipfs.io/blog/24-uncensorable-wikipedia/
http://observer.com/2017/05/turkey-wikipedia-ipfs/
So I propose that we use IPFS for any project that is at risk of government censorship.
