Hi ZmnSCPxj,

Thank you for your apologies.

>>> Just to be clear, I do not think = your additions to the base proof-of-stake can fix the issues introduced by = proof-of-stake.

No problem. After thinking about my experimental id= ea to use a formula to give more weight to coins together in a single addre= ss I think it wouldn't work as I expected.

But what I'm defending here is the standard PoS v3.= 0 which as far I know is something like a "gold standard" in PoS.

There are also more "modern" techniques n= ot included in PoS v3.0 that could be added like evaluating blockchain dens= ity to detect possible attacks which could also be used to improve security:

i.e.: as far I know, a 51% history rewrite attack c= an't be done in PoS if the attacker doesn't stop creating his 51% of blocks= in the main chain to make it shorter than his private fork, and that can be detected:

If nodes detect a hard fork starting in block N (an= d N has a minimum depth like 10 blocks or whatever), and the main chain has= a dangerous low block density between the tip of the blockchain and block N, instead of following the longest ch= ain, the nodes could start some emergency protocol like ignoring the new fo= rk.
