Why do you need a new coin for this?
From my point of view this could simply be a bitcoin wallet feature. Whenever you make a transaction, you would also make the 2% transaction to the institution's address (btw 2% is huge, this value will never entice people).
You can solve institution list management by having approved institutions send a colored coin "aidcoin" to a specific bitcoin address that the wallet would probe from time to time.
You need only to implement your own bitcoin wallet with these features and have people adopt it.
Hi riclas,
Has I understand, bitcoin 51% attack is a real threat, dedicated mining machines can in a near future kill the future of bitcoin. Read this please:
http://www.coindesk.com/51-attacks-real-threat-bitcoin/Of course bitcoin gained his place in history, no one gone take that from the bitcoin community. But I believe that an altcoin needs to be the new de-facto digital currency.
One that do not allow for mining rigs, no dedicated chips, give less power to GPU's and promote the CPU mining, so anyone can get return from mining. And so making the a 51% attack a less probable issue. Because more distribution of the mining process will solve this.
Of course when this new de-facto currency became real, we might create those type of wallets to allow donations, but for now, its time to start from the beginning with our one currency to test this concept. This coin will have same stability on the exchange markets that other coins will never have, because this mandatory donation of 2%.
Regards.
