š Original message:> There is a smarter way. Just send 0.01 BTC per block to the timelocked
outputs. Now, we have 6.25 BTC, so it means less than 0.2%. But that
percentage will grow over time, as basic block reward will shrink, and we
will have mandatory 0.01 BTC endlessly moved, until it will wrap. And guess
what: if it will be 0.01 BTC per block, wrapped every 210,000 blocks, it
simply means you can lock 2,100 BTC in an endless circulation loop, and
avoid this "tail supply attack".
My understanding of this is that it would basically remove 0.01 BTC rewards
from the next 210k blocks, and then do nothing.
After 210k blocks have passed, you're just rolling it forward, taking from
the anyone can spend output and locking it in a new one for 210k blocks
from now.
You're basically just using the next 210k block's reward to create a stash
of forever locked coins in a loop.
Unsure how this solves or relates to the smoothing of block rewards. Let me
know if I misunderstood.
