Re: On block rewards


Hi all,

I'm not really open to changing the reward schedule at this point, sorry. We can find a number of very valid arguments for a limited supply, as well as a number of very valid arguments for an infinite tail emission. Both set of arguments will be equally convincing.

My current position is the following: let's talk about this again in 3 years. And I could provide a number of very valid arguments for why that makes sense :-)

Now going back to the original topic of emission in the first few hours or days, while I empathize with the intent to have everyone start with as little stress as possible, it gets too messy for too little reward (pun intended). Zero outputs and fees would require special rules that would have to stay in forever. They would also necessitate special handling to prevent free spamming right from the start. Starting a new chain is complex enough as it is, let's not add more complexity around it. The absence of bad surprises is the best way to have a relatively serene start.

If a miner or pool messes up in the first day, there will be plenty of time to catch up.

- Igno

P.S. Still, thanks to everyone who chimed in!
