- 2025: a BIP introducing some form of post-quantum cryptography for wallets passes
- 2030: 99% of Bitcoin wallets are now QC-proof ; 99% of computer world is QC-proof as well
- 2032: QC breakthrough ; corpos can break old / lost / satoshi's wallets ; the rest of computer world is safe
THEN: what happens ? => This topic is to discuss the
THEN WHATApart from reused addresses, the only old addresses possibly affected by this kind of attack are P2PK. Accordingly preventative measures could be taken to make coins from this address type unspendable in the future (i.e. a hard fork that makes inputs from P2PK addresses invalid [though maybe that's not technically possible for reasons I'm not aware of]). Whether the community would be up for it is a different question of course, but under such circumstances I guess an argument could be made to consider these coins burned; giving the original owners a grace period of course to move coins to a new address first.
Assuming no such hard fork happens and QC indeed becomes viable at scale, deriving the private keys of satoshi's old stash will likely still take a considerable amount of time and resources, which means these coins are unlikely to hit the market all at once. In a way it would be like mining, just with larger variance. Currently P2PK addresses hold 1.7M BTC [1], i.e. 8% of Bitcoins end supply. Recovering and releasing these coins into the market over the course of 1-2 years (speculative timeframe, but I doubt it would be much faster) will likely have limited impact. There's a psychological factor of course, but with years of anticipation for such an event to happen it will probably be only a short term fluctation, similar to when Silk Road shut down or FTX went under.

So we are talking first about 1.7M BTC, that's quite a lot on 21M
I previously made a post, not in Economics, about this "burn the coins" idea.
https://bitcointalksearch.org/topic/m.63966677 - Perishable UTXOs
Apparently, it is a frequent idea, and always rejected.
To be honest, I think the reasons to avoid that are really good, and a Great Dip would be preferable.
This topic is kind of a "what if we don't do that" following episode of the Perishable UTXOs.
About the release time-frame, this is a good idea that I did not think about, maybe some QC expert could enlighten us on that aspect ?
What I am kind of sure though, is that this 1.7M BTC bag will be one of the biggest money incentive to develop QC: if BTC is not a world-wide reference by this time, its price will probably be at least 200k$, rising the bag's value to at least 340 Billion dollars.
This topic is here to start this anticipation you are talking about.
Let's imagine the market, if an additional 340B$ was slowly dumped in 2 years ?
Comparing it to current mining, it would be like a 32.41 BTC addition to every block reward, rising it to 35.53 BTC per block. That is ~11.37x the miners' selling pressure.
We could put this calculation in a spreadsheet, to have better precision, but if we imagine that such an event happens in one or two Epochs, the pressure would actually be ~22.7x to ~45.5x.
I think the "size" of the dip will mostly depend on the "wallet mining" speed.
Been on this forum for quite some years and quantum computing is still not the thing. There was a time when users of this forum used to say that quantum would break the bitcoin security and hence nobody should invest in crypto. Unfortunately their wet dream never came to reality and on the other hand bitcoiners became rich with their bitcoin.
So doomsday predictions and all that - I see a similarity with that type of mentality and what is being talked about here. I would rather enjoy the present and use bitcoin than wait for someone to break it let alone live that long to be able to see that.
I understand your point, and it makes sense.
But I might be filled with more hope, or just be younger than yourself, and believe that I will live this event.
And if not, maybe this topic's reflections can help the future ? Who knows..
Though I agree on enjoying the present ! Thinking about one future eventuality should not ruin the present.[/list]
