This video explains the main concept of the Lightning Network: creating
a bidirectional payment channel between two parties
Since Alice and Bob expect to transact more frequently, they decide to open up
a bidirectional payment channel, and use this to send the bitcoin.
To set up
a bidirectional payment channel, both parties involved must first agree on an opening transaction.
In the previous article, Alice and Bob established
a bidirectional payment channel.
This first part of the series establishes the necessary building blocks, and shows how these can be combined to create «smart contracts,» which can be applied to realize the first requirement of the Lightning Network:
a bidirectional payment channel.
This technology is all in various stages of development, with some of it being complete (P2SH, for instance) and some in very early states on Counterparty (such as
bidirectional payment channels and Lightning Network support).
Next,
this bidirectional payment channel set - up needs to expand to allow payments over a network.
So far, Alice and Bob opened
a bidirectional payment channel, which they both funded with five bitcoins.
Offchain settlement works by opening
a bidirectional payment channel between two parties: the client and the exchange.
This is the base implementation of micropayment channels; a more evolved implementation is the lightning network, which allows
bidirectional payment channels.
