It's not a deposit based system though. So none of that analogy applies to Lightning, the user controls their funds. Maybe talk of multi-sig use has caused you to assume otherwise
it is a deposit system though. watch the video!!
you have to get an address from a lightning hub to deposit funds into
this address is created using the hub. (hub and user make a multisig beginning with 2Mxzw...)
this address is the locking mechanism of the funds and requires lightnings authorisation to unlock, to avoid replay attacks/double spends onchain.
EG if the 2Mxzw address used in the demo solely belongs to the user.. then the user can buy 20 ASCII cats.. offchain. and simultaneously move funds out onchain.
but due to lightning needing to sign too, it locks funds in so that users can then make requests offchain using offchain 'coins'/units (millisats) and not able to touch the onchain funds.
the hub has a fee. and even funnier the hub is creating more "units" (3 extra decimals called millisats) where 0.04000000btc becomes 4000000000 milisats (0.04000000000) btc
as shown by
0.03924280000 millisat amount held (0.03924280 sat deposited)
0.00067600000 millisat fee taken (0.00067600 sat fee)
lightning has potential to help people who spend often. but lets not "do a carlton" and pretend its gods solution to everything bfore its even proven itself, before its removed its issues, bugs, flaws.
and before people like him have yet to understand it.
the video is just a phase 1 demo. im sure when they fix the flaws (big one is the extra 3 decimals which will cause issues) that in a few months it will become more clearer to people like carlton to 'maybe' understand it better.
also it has to be noted its the first TESTNET transaction.. not bitcoin.
because if its not involving bitcoins blockchain, its not bitcoin. (testnet is just an altcoin emulating bitcoin to act as a sandbox)
