I pledge 1000 IOTA (payable after launch) for a short description understandable for the average bitcoiner of
1) how and why consensus in IOTA works
2) how and why it solves scalability
3) why zero fees are possible
We could post this on reddit etc.
Feel free to add IOTA to the pledge, if you think this is important.
I add 100 Iota. I invested a small amount in the crowdsale because I didn't understand how it works and I still don't.
