-snip

Raspberry Pi 4's CPU is much faster than 3B+'s. 1 GB version seems to be priced the same as the third model, at least in my country. If I were you, I would buy 2 GB or 4GB model of Raspberry Pi 4 and HDD rather than 3B+ and SSD. The fourth model has USB 3.0 and gigabit Ethernet unlike previous models. Buy a small SD card only for the OS, either 8 GB or 16 GB one.

Fair enough; difference seems to be of around 20€ using a 1TB HDD and a 2GB pi 4B and 30 if raspberry of 4G. I'll give it some thought while I wait for the retailer to restock (looks like mid-July  Undecided) and if I happen to come accross any more doubts; I'll try to get them solved!

Thanks for the help!


Edit: Just realized that supply cable was not included; price has gone up a bit to around 80€ on Raspberry 4 4Gb without the HDD, against 40€ of Raspberry 3

Did That Mean The 1 Satoshi (Rounded Down Satoshi) Is Left Behind On The Multisig Wallet?

Firstly, you wouldn't be able to open such a small channel due to dust limit. Let's assume that numbers are much higher (5000.1 sat and 4999.9 sat). Leaving 1 satoshi would not make any sense (dust limit) so the only reasonable answer is that it would be added to the fee.

What If The Channel Opener [X] Had So Little Balance That Will Not Enough To Pay For Fee? Did [Y] Must Give [X] Some BTC So He Can Pay For The Closing Fee?

By default, the funder [X] is obligated to cover all fees. The fee rate is negotiated before funding a channel and it can be changed anytime if both parties agree. [Y] won't be obligated to cover the closing fee. If the fee is too low then the channel MAY fail. Last commitment transaction will be used in such case.

BTW I See That There's A Minimum Time Limit Before A Party Can Close A Channel(A Party Can't Close A Channel Before XX/XX/XXXX). Did That Achieved By Timelock or by The Lightning Protocol Itself?

I have never heard of such limitation. One should be able to close a channel even before the funding transaction gets confirmed.

Watchtowers - they will be responsible for taking care of people attempting to cheat while the other party is offline.

This feature is now available in Lightning Labs' implementation of the Lightning network. Currently, only altruist watchtowers are available. What are they? This kind of watchtowers doesn't take a cut if one party attempts to cheat; all funds are returned to the victim. Reward watchtowers should be available in the next release.

I would like some of your reactions/replies. Someone from Bitrefill once said that Lightning is like an "organized - serialized mempool". Any opinions?

I don't think this is a very good description, personally. The only notable similarity between a Lightning Network payment and an vanilla Bitcoin transaction seen in a node's mempool is that neither one has yet been confirmed in a block. There are significant distinctions between the two, though. For instance, the Lightning payment can be immediately used in a subsequent transaction without waiting for a block confirmation to occur.

Technically, merchants could accept 0-conf transactions which would be instant in such case but that would expose them to double-spending. Instead of believing users, they can set up a Lightning Network node and trust themselves.

Merchants transact in fiat,
Most immediately convert BTC to fiat upon receipt making sure they don't lose money on btc instability.
Lightning network is even worse as the time locks insure no quick fiat conversion.

Meaning if a Merchant does use LN, they do it thru a 3rd party service that offers almost instant fiat conversion.
Otherwise , a small $1000 variance lower in BTC verse fiat could have a devastating effects on their fiat profit margins.

Merchants want stability in price , odds are Libra become more popular than LN with merchants.

If LN is to make inroads with merchants theirs needs to be price stability added.
Find a way to do that, and you could increase merchant adoption.

That's basically the same as the current situation: most merchants use a payment processor to take care of the Bitcoin transaction, and get paid directly in fiat. I don't even think the merchant has to choose for LN, once his payment processor accepts it, it gets added just like some merchants accept many different altcoins.

Actually, not most of them, according to old news :

BitPay, the largest and oldest bitcoin payment processor with a daily volume of $1 million bitcoin transactions supporting more than 44,000 merchants, stated in an email exchange to CCN that more than 4,400 of their merchants keep all of their settlement in bitcoin, almost 18,000 keep some of their settlement in bitcoin while the remaining 22,000 convert it all to fiat.

If LN is to make inroads with merchants theirs needs to be price stability added.
Find a way to do that, and you could increase merchant adoption.

Without market control/manipulation or peg Bitcoin with more-stable asset, it's almost impossible,

But the coins are not yet settled in the blockchain, but "suspended" in payment channels. In another way, calling it an organized-serialized mempool is correct. Or maybe a zero-conf payment network? Cool

Since Libra will be based on the blockchain, I would hope someone can integrate Libra in LN too. Also, the merchant can accept BTC and then do an atomic swap for Libra, Tether, or whatever "stablecoin" that they prefer.

Sounds great but that's a false statement. I would rather stick to organized and serialized.

Since Libra will be based on the blockchain, I would hope someone can integrate Libra in LN too. Also, the merchant can accept BTC and then do an atomic swap for Libra, Tether, or whatever "stablecoin" that they prefer.

I haven't read much about Libra so I can't say if it's possible. Every Bitcoin fork with SegWit support can run the Lightning Network by making a few small changes in its code. It would be better if developers focused on improving the Lightning Network rather than wasting time on supporting another altcoin (assuming it was possible in this case).

Define "blockchain". Because I would say it's a database validated by $10 million dollar "honest" nodes. Hahaha.

Can I post Pollo Feed here? I've just had my daughter feed some chickens using the Lightning Network!
It's just 1000 satoshi ($0.10), and I love how someone made this just to use the Lightning Network! I found this site on Lightning Network Stores directory.
