As I understand it, LN would make instant (truly instant) transactions possible, and the lack of these seems to be one the major barriers on the way of using cryptocurrencies in real life for everyday expenses (apart from transacting online)
imagine it this way.
you have a plane that can travel around the world in 10 minutes for just 2 cents.
then you have a company that wants to install teleporters in every house
they advertise that the data stream can hop between teleporters. and if someone teleported and it hopped via your teleporter you get paid
seems great right. travel around the world in seconds. and get paid if someone else teleported via you.. wow amazing.. (not quite)
the teleporter company bought up a group of plane engineers, and got them to engineer a teleporter.
now they want to tell the world that planes cant cope.
no more planes will be build and the ticket price of a plane should rise to kill off demand for a seat on the plane.
here is the picture though
for someone to get from A-E they need to pass through B, C, D because A doesnt directly connect to E via the data streams
so A needs to pay B. and pay C and pay D to ensure A reaches E
costing A 4 hops
so what A does instead is find hub X which has multiple data streams to everyone.
now A can travel to E just by paying X twice
a-> X
X-> e
much cheaper than 4 fee's of the hop concept
a->b
b->c
c->d
d->e
but by going through a hub instead of hops, now e,d,c,b wont get paid...
and thats where it falls apart.
the fake promotional sales pitch to get B,C,D,E to promote LN.. but ultimately B,C,D,E wont get paid when it actually plays out in reality, because everyone will want to save money and use hubs instead..
and thats the agenda. blockstream need LN for blockstream to be the hub to gathr fee's for their $90m investors
another thing..
before using the teleporter A needs to sign a contract. handing his life to X and enters the teleport buffer
if something goes wrong and say X refuses to hop.. A loses his life (because E caused a chain reaction that made X lose his life. which made A want to get out which forced X to revoke A's life to compensate X for the loss against E)
secondly if A decides he would rather not use a teleporter and tries getting out of the buffer early.
A is then in limbo for 3-5 days dematerialising and cant move... and if X objects to A leaving A loses his life
yes i have used a sci-fi analogy of how it LN works but if i was to use the more realistic bank2.0 analogy, the centralists would should hell fire comparing their commercial tool to a bank
