Would it make sense to have some partial/incremental SHA256 implementation? E.g. one that gives the first character only (in ASCII representation). So that you could have a cheaper money miner to narrow down the search space? Is it even possible to have cheaper first character SHA256 algorithm?

>Is it even possible to have cheaper first character SHA256 algorithm?

What would be the goal of that? Do you want a cryptographic hash function, or do you want something else?

Well, such an algorithm existing would be a massive breakthrough in cryptography research. The answer should be no since that make it easier to do a preimage attack than brute-force.

This is essentially how bitcoin's proof of work algorithm works. They maintain the difficulty by adding 0s as computers get faster.

Yep. So much compute and energy thrown away because proof of stake wasn't figured out sooner.

You need some proof of work to prime the pump for proof of stake. Otherwise, you have no security because there's nothing at stake.

Now that we have plenty of proof of work completed, we don't really need any more. You can bootstrap your new coin by burning Bitcoins as a provable value sink to get it started on the path to POS.

You could stake fiat in a bank account I guess?

Coding and testing JS with the help of ChatGPT is several multitasking levels above what I’d be willing to even try on a phone. Android, I assume? Big screen? BT keyboard even?

It was actually much easier than I expected. Just asked for it as a single HTML page, copied the output to a file and opened it on Chrome. Did very few adjustments.

Can you share that ChatGPT conversation, please? (There is a share link in ChatGPT.) Thank you.
