I still feel that confiscating stale addresses is what will be done.
How many 2009 to 2010 blocks have zero withdrawals a lot maybe 10,000 blocks of 50 coins each were never touched.
NO, this is one of the worst possible proposals in practice. Think about it. You have two paths here. I will use 1M confiscation to keep the example simple.
- Option 1: Increase the limit by 1M to 22M and slowly issue this. Total supply changes right now, circulating supply changes as these get issued.
- Option 2: Do not increase the limit, but confiscated 1M of old coins. Total supply stays the same, circulating supply changes as these get reissued.
In practice, option 2 is much worse than option 1. While traditionally the limit is defined by the total supply, in practice what matters is circulating supply. Think about it. If for some weird technical reason you had to increase the total supply by a factor of 100x, but 0% of these coins entered circulation, what changes in practice? Nothing. There would be bad PR for sure, but the limit of 21M circulating coins would remain the same. In the option that you talk about, option 2: you get both an increase in circulating supply and a precedent of confiscation. It attacks two of the most important points of Bitcoin. Please note that I am not advocating for a supply increase, I am merely saying that between two such options that the latter is much worse in practice.
This solution requires fractional satoshis. To make things simple, I propose dividing a satoshi into 100 million parts (because the demurrage cost is 1/100 million).
More complexity and more units is not desirable. Anyhow, if I understood you correctly your proposal will punish the best holders for simply holding. This is a terrible incentive.
2. Lost coins and dust are eventually recovered.
Replace one type of confiscation with another? How do you know that my coins are lost, because I am not using them actively?
There are simpler ways to approach this, not necessarily the best ways of course. You can introduce a primary flat miner fee, and retain the variable fee from the fee market on top of it. For example, a flat fee of 100 satoshi as of today would be $0.11. At 3000 transactions per block, that is an extra 300 000 sats. Over a year using current prices that is an extra $17M for miners. No burn, no demurrage, no confiscation, no supply increase.
Where we stand today, this is not even yet a problem let alone one that requires immediate intention. Most of this speculation is coming from altcoin advocates who want to prove POW and Bitcoin's fair economics wrong, and prove POS, token-printing and selling as correct. Do fees need to always stay high? No. Does the hashrate have to always increase? Also no.
