total funds. meaningless. one dude could set up 2 nodes and channel between him and.. himself. fund that channel with any amount..
but thos funds are not what the community get to touch or use.

also do some maths. or check the stats. each channel is about 0.001 meaning if i sent a payment that routed through all the channels of 0.001.  then move their 0.001 out of their control in that direction. meaning if anyone else wanted to follow in a similar direction route. the channels wont be able to.

from this
me [0.001 <> 0.000] A [0.001 <> 0.000] B [0.001 <> 0.000] C [0.001 <> 0.000] D [0.001 <> 0.000] E [0.001 <> 0.000] F
to this
me [0.000 <> 0.001] A [0.000 <> 0.001] B [0.000 <> 0.001] C [0.000 <> 0.001] D [0.000 <> 0.001] E [0.000 <> 0.001]  F

A can no longer pay any other alphabet person
now imagine you joined A and wanted to pay F... YOU CANT..
take note.. even in the "from this" start point. although there is 0.006 ntwork capacity.. NO ONE can send more than 0.001.. and once 'me' has spend just 0.001 to F... (well ill emphasise it again)
A, B, C,D,E  CANNOT PAY F anything!


also. do the 'degrees of separation' maths
if 5 people. know 4 DIFFERENT people(meaning 5 channels but 4 new people as one is linked to the parent).. who know 4 DIFFERENT people and so on.
5
20
80
320
1280
5120
20480
in 6 hops you reach a capacity of ~20k people.. but only one route to get from one end of the network to the other

now if you have 5 channels but they are not all to new unique people. but aswell as using a channel to backchannel to the parent. one of the 5 channels is also connected to soneone else . thus allowing for 2 routes somewhere in the network
5
15
45
135
405
1215
3645
10935

in 7 hops you reach a capacity of ~11k people.. but only maybe 2 routes to get from one end of the network to the other

this is somthing people can do without even using LN. use some paper and pen and draw dots and lines.. doing on graphics/doodling apps. if you prefer to do the math instead of image format.. then do it on excel.
you will see the limitations

people really should run scenarios. use it. or think about it.. rather then promote it as the unlimited flawless solution without understanding its real utility limitations.

I also can not understand this lightning network. there may be a smarter to be able to provide an understanding of this lightning network. understanding that is easy to understand.

I wonder what does it and how does it work. And what is the difference between the lightning network and the full network blockchain?

Definitely. Lightning network will be an easiest way to keep transaction goin' on to the bitcoin blockchain without willing to set up a full node.
