Sorry to draw for the confusion as PoC is more\ncommonly used then PoST.\nThere is a way to make PoC cryptographically compatible w/ Proof of Work as\nit normally stands: https://en.wikipedia.org/wiki/Proof_of_space\nIt has rarely been done though given the technological complexity of being\nboth CPU compatible and memory-hard compatible. There are lots of benefits\noutside of the realm of efficiency, and I already looked into numerous\nfault tolerant designs as well and what others in the cryptography\ncommunity attempted to propose. The actual argument you have only against\nthis is the Proof of Memory fallacy, which is only partially true. Given\nhow the current hashing algorithm works, hard memory allocation wouldn't be\nof much benefit given it is more optimized for CPU/ASIC specific mining.\nI'm working towards a hybrid mechanism that fixes that. BTW: The way\nBitcoin currently stands in its cryptography still needs updating\nregardless. If someone figures out NP hardness or the halting problem the\ntraditional rule of millions of years to break all of Bitcoin's\ncryptography now comes down to minutes. Bitcoin is going to have to\neventually radically upgrade their cryptography and hashing algo in the\nfuture regardless. I want to integrate some form of NP complexity in\nregards to the hybrid cryptography I'm aiming to provide which includes a\npolynomial time algorithm in the cryptography. More than likely the first\nversion of my BTC hard fork will be coded in a way where integrating such\ncomplexity in the future only requires a soft fork or minor upgrade to its\nchain.\n\nIn regards to the argument, \"As a separate issue, proposing a hard fork in\nthe hashing algorithm will invalidate the enormous amount of capital\nexpenditure by mining entities and disincentivize future capital\nexpenditure into mining hardware that may compute these more \"useful\"\nproofs of work.\"\n\nA large portion of BTC is already mined through AWS servers and non-asic\nspecific hardware anyways. A majority of them would benefit from a hybrid\nproof, and the fact that it is hybrid in that manner wouldn't\ndisenfranchise currently optimized mining entities as well.\n\nThere are other reasons why a cryptography upgrade like this is beneficial.\nTheoretically one can argue BItcoin isn't fully decentralized. It is few\nunsolved mathematical proofs away from being entirely broken. My goal\noutside of efficiency is to build cryptography in a way that prevents such\nan event from happening in the future, if it was to ever happen. I have\nvarious research in regards to this area and work alot with distributed\ncomputing. I believe if the BTC community likes such a proposal, I would\nsingle handedly be able to build the cryptographic proof myself (though\nwould like as many open source contributors as I can get :)\n\nAnyways just something to consider. We are in the same space in regards to\nwhat warrants a shitcoin or the whole argument against staking.\nhttps://hackernoon.com/ethereum-you-are-a-centralized-cryptocurrency-stop-telling-us-that-you-arent-pi3s3yjl\n\nBest regards,  Andrew\n\nOn Fri, Mar 5, 2021 at 4:11 PM Keagan McClelland \u003c\nkeagan.mcclelland at gmail.com\u003e wrote:\n\n\u003e It is important to understand that it is critical for the work to be\n\u003e \"useless\" in order for the security model to be the same.
