SplinterNet 101

regardless of my works seeking to figure out ways to reduce energy payload
for works (& dignity) i've ended-up looking into the recent 'John McAfee'
stuff; which led me to block-chain based Domains, Brave and a bunch of
different options - that i don't really understand well..

seems there may be something grown; that i didn't look into alot, and may
well replace HTTP/WWW as a form of 'upgrade'...

Questions are: what's the difference between different 'wallets' (ie:"
https://metamask.io/ vs. others); do they provide access to different
'splinter-webs'?  are they harmonised in some way?

If someone is looking to learn about it - what are the best resources?

Seems data is generally stored on IPFS as to not 'over-load' ETH?  Or can
you dump terabytes onto ETH?  How does that relate to 'private
blockchains'?  is there a guide for dummies somewhere?

What i found 'really interesting' is that it is said; john Mcafee loaded a
complex 'dead man switch' to deliver a payload in the event of him getting
'suicided'...  i know a few who have (imo); but this is still an 'emergent
concept'...

So how does it work?

thoughts?

NB: wasn't my focus, my focus was more about support for 'rule of law'
rather than assuming 'worse'. as such, not a field where I have expertise.
Given the potential RWW utility, i thought i'd make a note of it.
Certainly one potential future is a private blockchain 'life log', i am
still concerned about the energy implications; but perhaps, depending on
corruption calcs, its cheaper..  IDK.
