I'm glad to see this coin moving forward.
50% of coin supply for shareholders is already quite low, I am against additional reservations, keep in mind that other 50% is already reserved for various purposes.
having public key on nxt is new kora shareholder requirement? first time i see this mentioned. may be little annoying for first time nxt users.
Don't forget that the initial 50% distribution to stakeholders is at the beginning, but further distribution will happen later too.
Here is the distribution:
50% - distributed equally to ~3000 webapp registration applicants
5% - goes to the registration webapp dev
5% - goes to the dev who clones Qora, and creates the Kora wallet applications
2% - Kora founder
8% - goes to node bot bounties
4% - website & marketing
1% - Qora dev
25% - POWER BOUNTIES
37% more will be distributed to community members (8% + 4% + 25%), but that will go to people for "doing things", and that's a key part of the (K)Ora strategy - having enough resources to reward & motivate people into the future.
The 'dev' share is 12% (5% each to Mac Red & nioccoin, and 2% for me)
Last, but not least, is 1% to the Qora dev as a thank you for using his source code (in what exact way will be decided by nioccoin).
So, 87% will go to community members (99% if you count Mac Red, nioccoin & me as part of the community). The key is 50% is 100% FREE, and the remainder will be paid to people who do useful 'things' for the community as judged by ALL of us.
I think the balance is OK (I hope!)
As for the public key requirement, that's to protect YOU. If you don't have a public key attached to your NXT account you aren't fully protected with 256 bit encryption, so that 'requirement' is really there to protect NXT newbies.
