If it isnt broken, dont fix it. Dont understand why ppl pursue PoS when proof of work will do fine.

That being said its tempting to think about proof of stake and how to solve the issues it faces to get something that works.

One of the unsolved issues for Ethereums PoS-model is that there is no cap on the number of active validators which is a problem because keeping track of the 400k+ current validators consumes alot of bandwidth and IO and solo stakers are reporting bandwidth usage of 5-10TB per month, this is before the blocksize increase to about 1mb (EIP-4844) which will boost bandwidth consumption further but thats beside my point. iirc the safer number of active validators is around 180k, so i am interesting to see how they solve this.
