Dissecting Hard Forks and Quadratic Voting

some of the misunderstood terms:
hard forks: means deciding to agree differently on which chain to consider valid .
suppose bitcoin was hard forked on mid 2014 to create side blockchain of BCH and original chain remains as of btc. on the contrary, ethereum after being hacked on sometime between 2015 , in order to force hacked funds to be de-valued, original chain was shit dumped as ethereum classic and vitalik, joseph lubin and vlad zamfir team created side chain which is now eth blockchain. I confused it with forking repo on github
Quadratic voting:
Donating small amounts to Gitcoin grants is a lot of fun, because you’re constantly multiplying your value. Often a $10 grant becomes a $100 or even $500 donation, thanks to the power of spending other people’s money via Quadratic funding
