Sorry to draw for the confusion as PoC is more&#xA;commonly used then PoST.&#xA;There is a way to make PoC cryptographically compatible w/ Proof of Work as&#xA;it normally stands: https://en.wikipedia.org/wiki/Proof_of_space&#xA;It has rarely been done though given the technological complexity of being&#xA;both CPU compatible and memory-hard compatible. There are lots of benefits&#xA;outside of the realm of efficiency, and I already looked into numerous&#xA;fault tolerant designs as well and what others in the cryptography&#xA;community attempted to propose. The actual argument you have only against&#xA;this is the Proof of Memory fallacy, which is only partially true. Given&#xA;how the current hashing algorithm works, hard memory allocation wouldn&#39;t be&#xA;of much benefit given it is more optimized for CPU/ASIC specific mining.&#xA;I&#39;m working towards a hybrid mechanism that fixes that. BTW: The way&#xA;Bitcoin currently stands in its cryptography still needs updating&#xA;regardless. If someone figures out NP hardness or the halting problem the&#xA;traditional rule of millions of years to break all of Bitcoin&#39;s&#xA;cryptography now comes down to minutes. Bitcoin is going to have to&#xA;eventually radically upgrade their cryptography and hashing algo in the&#xA;future regardless. I want to integrate some form of NP complexity in&#xA;regards to the hybrid cryptography I&#39;m aiming to provide which includes a&#xA;polynomial time algorithm in the cryptography. More than likely the first&#xA;version of my BTC hard fork will be coded in a way where integrating such&#xA;complexity in the future only requires a soft fork or minor upgrade to its&#xA;chain.&#xA;&#xA;In regards to the argument, &#34;As a separate issue, proposing a hard fork in&#xA;the hashing algorithm will invalidate the enormous amount of capital&#xA;expenditure by mining entities and disincentivize future capital&#xA;expenditure into mining hardware that may compute these more &#34;useful&#34;&#xA;proofs of work.&#34;&#xA;&#xA;A large portion of BTC is already mined through AWS servers and non-asic&#xA;specific hardware anyways. A majority of them would benefit from a hybrid&#xA;proof, and the fact that it is hybrid in that manner wouldn&#39;t&#xA;disenfranchise currently optimized mining entities as well.&#xA;&#xA;There are other reasons why a cryptography upgrade like this is beneficial.&#xA;Theoretically one can argue BItcoin isn&#39;t fully decentralized. It is few&#xA;unsolved mathematical proofs away from being entirely broken. My goal&#xA;outside of efficiency is to build cryptography in a way that prevents such&#xA;an event from happening in the future, if it was to ever happen. I have&#xA;various research in regards to this area and work alot with distributed&#xA;computing. I believe if the BTC community likes such a proposal, I would&#xA;single handedly be able to build the cryptographic proof myself (though&#xA;would like as many open source contributors as I can get :)&#xA;&#xA;Anyways just something to consider. We are in the same space in regards to&#xA;what warrants a shitcoin or the whole argument against staking.&#xA;https://hackernoon.com/ethereum-you-are-a-centralized-cryptocurrency-stop-telling-us-that-you-arent-pi3s3yjl&#xA;&#xA;Best regards,  Andrew&#xA;&#xA;On Fri, Mar 5, 2021 at 4:11 PM Keagan McClelland &lt;&#xA;keagan.mcclelland at gmail.com&gt; wrote:&#xA;&#xA;&gt; It is important to understand that it is critical for the work to be&#xA;&gt; &#34;useless&#34; in order for the security model to be the same. If the work was&#xA;&gt; useful it provides an avenue for actors to have nothing at stake when&#xA;&gt; submitting a proof of work, since the marginal cost of block construction&#xA;&gt; will be lessened by the fact that the work was useful in a different&#xA;&gt; context and therefore would have been done anyway. This actually degrades&#xA;&gt; the security of the network in the process.&#xA;&gt;&#xA;&gt; As a separate issue, proposing a hard fork in the hashing algorithm will&#xA;&gt; invalidate the enormous amount of capital expenditure by mining entities&#xA;&gt; and disincentivize future capital expenditure into mining hardware that may&#xA;&gt; compute these more &#34;useful&#34; proofs of work. This is because any change in&#xA;&gt; the POW algorithm will be considered unstable and subject to change in the&#xA;&gt; future. This puts the entire network at even more risk meaning that no&#xA;&gt; entity is tying their own interests to that of the bitcoin network at&#xA;&gt; large. It also puts the developers in a position where they can be bribed&#xA;&gt; by entities with a vested interest in deciding what the new &#34;useful&#34; proof&#xA;&gt; of work should be.&#xA;&gt;&#xA;&gt; All of these things make the Bitcoin network worse off.&#xA;&gt;&#xA;&gt; Keagan&#xA;&gt;&#xA;&gt; On Fri, Mar 5, 2021 at 1:48 PM Lonero Foundation via bitcoin-dev &lt;&#xA;&gt; bitcoin-dev at lists.linuxfoundation.org&gt; wrote:&#xA;&gt;&#xA;&gt;&gt; Also in regards to my other email, I forgot to iterate that my&#xA;&gt;&gt; cryptography proposal helps behind the efficiency category but also tackles&#xA;&gt;&gt; problems such as NP-Completeness or Halting which is something the BTC&#xA;&gt;&gt; network could be vulnerable to in the future. For sake of simplicity, I do&#xA;&gt;&gt; want to do this BIP because it tackles lots of the issues in regards to&#xA;&gt;&gt; this manner and can provide useful insight to the community. If things such&#xA;&gt;&gt; as bigger block height have been proposed as hard forks, I feel at the very&#xA;&gt;&gt; least an upgrade regarding the hashing algorithm and cryptography does at&#xA;&gt;&gt; least warrant some discussion. Anyways I hope I can send you my BIP, just&#xA;&gt;&gt; let me know on the preferred format?&#xA;&gt;&gt;&#xA;&gt;&gt; Best regards, Andrew&#xA;&gt;&gt;&#xA;&gt;&gt; On Fri, Mar 5, 2021, 10:12 AM Lonero Foundation &lt;&#xA;&gt;&gt; loneroassociation at gmail.com&gt; wrote:&#xA;&gt;&gt;&#xA;&gt;&gt;&gt; Hi, this isn&#39;t about the energy efficient argument in regards to&#xA;&gt;&gt;&gt; renewables or mining devices but a better cryptography layer to get the&#xA;&gt;&gt;&gt; most out of your hashing for validation.

I would argue that the negative&#xA;&gt;&gt;&gt;&gt; externalities will go away soon because of the move to renewables, so the&#xA;&gt;&gt;&gt;&gt; point is likely moot.&#xA;&gt;&gt;&gt;&gt;&#xA;&gt;&gt;&gt;&gt; _______________________________________________&#xA;&gt;&gt; bitcoin-dev mailing list&#xA;&gt;&gt; bitcoin-dev at lists.linuxfoundation.org&#xA;&gt;&gt; https://lists.linuxfoundation.org/mailman/listinfo/bitcoin-dev&#xA;&gt;&gt;&#xA;&gt;&#xA;-------------- next part --------------&#xA;An HTML attachment was scrubbed...&#xA;URL: &lt;http://lists.linuxfoundation.org/pipermail/bitcoin-dev/attachments/20210305/686f42d2/attachment-0001.html&gt;</html></oembed>
