Isn't it precisely what is implemented in Monero? (except you don't have a rollover pool, the penalty is simply deducted from the block reward for good).
No idea what happens in Monero, but if so, more power to them.
Apparently, neither does Gavin.
He said he didn't want to talk to you until there was working code that does it?
Such code has been working for years, but people forget where the experimentation is occurring, the alts.
Can you explain a bit about the mechanism wherein the miner pays into the rollover pool, and why that is different from the 'original proposal'?
The difference is quantitative. In this version the rollover effects only blocks that exceed a threshold of size.
