Good morning list,
> I describe here an algorithm based on semispace GC, but the GC algorithm =
space is well-studied and other algorithms may also be devised (in particul=
ar, spam is likely to match quite well with "infant mortality" concept in G=
C, i.e. "most objects die young", so some kind of nursery / generational GC=
may work better against spam in practice).
This "nursery GC" variation would be very similar to these "pre-mempool" / =
"memswamp" proposals, as well:
* https://github.com/bitcoin/bitcoin/issues/14895#issuecomment-665975441
* https://github.com/bitcoin/bitcoin/issues/14895#issuecomment-666267749
It may be better to continue thinking along those lines than to consider th=
is GC concept.
Regards,
ZmnSCPxj
