Investing in Chia is apparently another proof that human society can’t avoid the Herd behavior.
Chia doesn’t offer a better solution to Bitcoin as a currency: scarcity, durability, divisibility, portability, acceptance and stability. Instead, Chia has been promoted as a “green” alternative, although Chia is not truly green at all.
Technology wise, Chia has many unsolved issues. One of them is the pool model. I don’t think the issue has been challenged much so far since Chia is still relative minor.
Chia pool is a mimic of Bitcoin pool, which distributes a share of wealth by showing a proof a “capability”. In Bitcoin, the capability of work is real, because no matter how weak a possessor, it’s only a matter of time for the CPU/GPU/ASIC to win (of cause you may argue that statistically impossible for a weak processor to get anything, but the same logic holds for Chia).
On the contrary, Chia’s partial and full are not mathematically scalable from one to the other. The rationale is simple, just like staying an exquisite decorated room doesn’t mean the hotel and all rooms are as gorgeous as you have seen.
The white paper didn’t shows a proof of sufficiency that Chia partials ensures the scalability of final reward, even though the mathematical necessity could be assumed, I guess. Perhaps other readers could point out otherwise in the paper (for both necessity and sufficiency).
Moreover, the need of “storage space” seems being handled poorly in Chia, in a way of thinking as if PoS meant to be the bigger the more valuable. It’s sort like claiming a “better” dollar by having the bill big and heavy, like a gold bar.
Put it simple, it’s a waste of 100GB of storage space just to achieve the goal of “reserving a specific amount of storage space at that precise time”.
The show case of such waste is right inside Chia itself, just by comparing the data holding the “proof of time” vs “proof of space”. You can tell how inefficiency in the way Chia handles the model (a puny small VDF vs humongous 7-tables).
Nonetheless, Chia is a very creative cryptocurrency (I like it’s use of VDF, for example). Hope Chia can improve, or work out a better version.
