What are the inputs that must be considered when setting the eternal inflation parameters for a PoW coin? From technical perspective, I mean.
From economical perspective, 100 years of growth at 2% APR is 624% per century. Granted, century is a long time, but also the current system with its wasteful resource acquisition and general footprint on pristine nature, cannot continue 1-2 more centuries with this growth rate.
On the other hand, gold production of about 1.2% (historically higher ~2%) can be regarded as near optimal, because gold has held its value vs. oil in the last decades.
If the economic and population growth abate, 0% is of course optimal as you cannot go lower.
=> The quick thinking would point to 0.5%-2% bracket, and it must be percentage, not a fixed amount.
This is a really important matter. A 1%-point fail can easily destroy the coin. (see silver inflation in 1850-1870 for instance how a precious metal was destroyed)
I don't think he was talking about an X% increase in coin supply. He was talking about a perpetual 1 coin per block. You will notice that with each new block 1 coin is a smaller percentage of the total money supply. Eventually it will become so small that the value of securing a marginal unit from loss due to carelessness will be less than 1 coin per block. And thus we would reach an equilibrium where about 1 coin per block was lost due to carelessness and 1 coin per block is created in mining. The beauty of a proposal like this is that it leads to a stable money supply. No deflation or inflation.
I would rater say that to achieve what you say anon, you need a fix x% per year of coin creation to counter the Lost "due to carelessness". I think that loss should be account for a percentage of the total market number of atomic coins. The problem is to define the "x" value, I agree that this is not easy. Instead, with a fix amount, it like saying in the limit of end of time that there is less and less people that are losing the coins due to carelessness. Maybe that thinking is also incorrect...
In the end, maybe the creation of coin that should counter loss should not be count on x% or "y" fix number of coins per block, but be count in term of coin inactivity in the last "average life time" of a human life. After that time of inactivity, we can expect that the coins are lost, so they need to be replace...
Maybe i didn't explain myself clearly enough. So lets say that each new block is introducing 1 monero. And lets say that people are losing 0.5 monero per block on average due to carelessness. So each new block is having 0.5 new monero be introduced into circulation on net. This causes inflation, which all other things being equal reduces the value of a unit of monero. Suppose this trend continues. If a monero is worth less, than it is worth less effort to secure it. Thus the less it becomes worth the less effort people put into securing it. Eventually if this trend continues enough the values will flip. So now now each block is introducing 1 new monero and people are losing 1.5 monero per block due to carelessness. This is causing deflation. Deflation increases the value of a unit of monero. Thus increases the value of precautions to ensure against loss due to carelessness. And the process repeats.
