Re: Will a shorter block time be helpful or harmful to Bitcoin and its future?
Confirmation eta is based on the target difficulty the bitcoin software determines. The higher the difficulty, the longer the time between confirmations (on average). So by making confirmations happen twice as often (every 5 minutes or so, ideally), the security granted by that confirmation represents half the work to secure your money (because the confirmation is easier to get, and thus an attacker could potentially "luck out" and get a block that much easier.
Perhaps if you don't know how the system works, you shouldn't propose changes to the fundamentals of bitcoin

So if I understand you correctly, the higher the difficulty, the longer the confirmation eta? Does this mean that confirmations will get infinitely longer as time progresses?
Also, I wasn't proposing a change to Bitcoin. I was simply starting a discussion about modifying factors that affect confirmations. Also, it's a wonderful opportunity to pick up more knowledge. Gotta learn somewhere, right?
If you want secure 0 confirmation transactions, there are plenty of solutions to that (green address, off the chain tx, risk mitigation).
Could you please provide a link to something explaining green addresses and off the chain tx? If you know enough about them, you are welcome to post here as well. I'd like to know more.
