Topic: Can you think of ways to use LN offline? - page 2. (Read 521 times)

My thinking was this, let's say a group of businesses on a island wants to do transactions amongst each other, they can have their own LAN with the LN software running between these computers. and when they want to settle the balance of all these off-chain transactions, they connect/link to the Internet and the on-chain tx is done.

Yes, it is still a network, but it is not connected to the internet or the Blockchain, until they need to validate the finale balance, on-chain.

This implementation might even work within all environment where people are running their own LAN. This will increase security, because the network are only exposed to hackers, when they quickly go on-line to sync or validate the on-chain transactions. 

The lightning network(The word network shows the concept of communication/being online) consists of bi-directional channels so that both parties are connected to update the smart contracts between them and failure will result in the confiscation of their claim to any of the funds in the channel.
Channels in the lightning network will be off-chain channels (You do not need to publish them on the entire network) but the parties must be connected to the signing of transactions.

If you want to send to an offline party via lightning network you can broadcast the transaction directly without creating a channel(using normal way).

You need to be online to use the Lightning Network, that's how it works.
Transactions (state updates) are almost instant so there's no need to wait for confirmation.
Not possible. LN commitment transactions are CONTRACTS so BOTH parties have to be online to approve.
Payments fail if a peer is offline.
$o in other words you need to give out your private key to someone else to accept transactions  for you?
That's not going to work.
The Lightning Network is a bidirectional transaction layer.
You'll need the cooperation of BOTH parties before you can accept commitment transactions or send out transactions.
And since you need both participants need to sign transactions, by introducing a third party, you'd have to share private keys to the third party which it'll use to sign transactions.

The Lightning Network is p2p -- perhaps even "more p2p" than bitcoin, because there are no miners or other nodes. It's just between peers.
There's no memory pool equivalent for transactions to be stored, and transactions clear quickly enough that it's not needed, so there's no place for transactions to be stored when the counterparty is offline or unavailable.

However, if you do not need trustlessness then you can make something work with a third-party service like ACINQ'S Strike, where their lightning node will always be online and accept payments on your behalf.

Anyone able to contribute to this technical conversation?

Basically looking for ways that LN will be usable by clients or merchants who have no connectivity for a period of time.

E.g. you've gone to some market place or conference hall and there is no cell reception or Wifi.

Thanks,
