Since the instructions say to email bitcoin-dev before doing a bip draft, I have done that.

There are lots of benefits outside of the realm of efficiency, and I already looked into numerous fault tolerant designs as well and what others in the cryptography community attempted to propose. The actual argument you have only against this is the Proof of Memory fallacy, which is only partially true. Given how the current hashing algorithm works, hard memory allocation wouldn't be of much benefit given it is more optimized for CPU/ASIC specific mining. I'm working towards a hybrid mechanism that fixes that. BTW: The way Bitcoin currently stands in its cryptography still needs updating regardless. If someone figures out NP hardness or the halting problem the traditional rule of millions of years to break all of Bitcoin's cryptography now comes down to minutes. Bitcoin is going to have to eventually radically upgrade their cryptography and hashing algo in the future regardless. I want to integrate some form of NP complexity in regards to the hybrid cryptography I'm aiming to provide which includes a polynomial time algorithm in the cryptography. More than likely the first version of my BTC hard fork will be coded in a way where integrating such complexity in the future only requires a soft fork or minor upgrade to its chain.

If the work was useful it provides an avenue for actors to have nothing at stake when submitting a proof of work, since the marginal cost of block construction will be lessened by the fact that the work was useful in a different context and therefore would have been done anyway. This actually degrades the security of the network in the process.

This is because any change in the POW algorithm will be considered unstable and subject to change in the future. This puts the entire network at even more risk meaning that no entity is tying their own interests to that of the bitcoin network at large. It also puts the developers in a position where they can be bribed by entities with a vested interest in deciding what the new "useful" proof of work should be.

For sake of simplicity, I do want to do this BIP because it tackles lots of the issues in regards to this manner and can provide useful insight to the community. If things such as bigger block height have been proposed as hard forks, I feel at the very least an upgrade regarding the hashing algorithm and cryptography does at least warrant some discussion.

📝 Original message:I really like ideas that tackle this issue. The question imho is what is
the incentive to run a "Full UTXO node" instead of a pruned or archive node.
For starters, it would be nice to know what would be the savings for Full
UTXO nodes over archive nodes right now.
Also, what advantages would this have over "archive pruned nodes: nodes
that store X blocks of the whole blockchain before 420000". Seems like an
interesting intermediate use case to me too.

I am of the same opinion, although i understand Gavin's point. Would
the multisig seed work for this purpose?
I have been toying with this idea and I think that for this BIP to
make sense it would require a "root" key as your login. Then if you
need to make transfers the system would request you to create and
associate a new key to your account for each purchase (signing the new
key with the root one for example).

On-topic:
This argument is quite the fallacy. The only reason we have that few
pools is because each of their miners doesn't find it feasible to mine
"on their own". if you count the individual miners on those pools you
will get to the scale Gavin was trying to point out.
Nevertheless i think that is just a minor disagreement, since tree
chains help decentralization.

make this a user experiment:
-give the user the possibility to use BTC/mBTC/uMTC
-retrieve the results after some time
-make the default the most used option
