FYI it’s generally considered bad form repost a private thread, especially one you initiate.

...

It’s typically more effective to generate some community support before actually submitting a BIP. Otherwise the process gets easily overwhelmed. This is likely why you aren’t getting a response. You can draft the BIP in your own repo and collect feedback from interested parties.

Posting a link to your research/code is a good start. I’d be happy to look at an overview of the central principles. I’m not a cryptographer. I write code, but I look at these things from economic principles. So far all I have to go on is that you go “much beyond” Chia. That’s not really anything.

I am trying to tackle cryptography in a way that goes much beyond that. Part of what I am doing includes lowering invalided proofs while trying to get the best of both worlds in regards to PoW and PoC. It is an efficiency issue to the core. In regards to the mechanisms of how I will do that, I suggest you look at the entire proposal which is why I am hoping the BIP team would be so gracious as to allow me to draft it out on GitHub.

Two years later, after they finally realized I was correct, one of their PhDs contacted me and told me. Better to flesh this out early. They had already raised $20 and done their research, so he wasn’t exactly in a listening mode.

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.

It is few unsolved mathematical proofs away from being entirely broken. My goal outside of efficiency is to build cryptography in a way that prevents such an event from happening in the future, if it was to ever happen. I have various research in regards to this area and work alot with distributed computing. I believe if the BTC community likes such a proposal, I would single handedly be able to build the cryptographic proof myself (though would like as many open source contributors as I can get :)

In other words, the apparent benefit represents a temporary market shift, with advantage to first movers. The market will still consume what it consumes.
