That isn't so. You learn that a channel doesn't have enough capacity by attempting to use it, failing, then updating your knowledge and trying again. It typically takes something like 1.25 tries on average in the current network. See Bolt 7: > Note that the htlc_maximum_msat field is static in the current protocol over the life of the channel: it is not designed to be indicative of real-time channel capacity in each direction, which would be both a massive data leak and uselessly spam the network https://github.com/lightningnetwork/lightning-rfc/blob/maste...

> What are the expected size of these transactions? LN deposit/close transactions don't carry any information about LN payments made on the channel, so their size doesn't grow with usage. They are simply 2-2 multisig transactions, so somewhat larger than the minimal 1-in-1-out tx, but probably (didn't check this) not larger than median bitcoin transaction. > And how does Segwit work for these transactions those are always pay-to-witness-script-hash transactions, so they don't even work without segwit: https://github.com/lightningnetwork/lightning-rfc/blob/maste... > current argument there will be too much competition for nodes hence people will automatically set low or no fees it's not as easy, there are multiple incentives and discentives working here. lowering fees will bring more volume but increase cpu/io load. higher volume also mean

s you need to have more capacity on your channels, which essentially means lots of funds in a hot wallet - a target for hackers. high volume also means you might become target for authorities wanting to track payments in LN. et cetera. > With LN nodes charging fees on top of it, businesses now will have two fees to account for? technically yes, but the fee for deposit transaction is paid only once per channel and merchants (usually) won't be involved with it. it's reasonable to assume that users will mostly fund channels with larger nodes because that brings better connectivity (you don't want to have a channel with starbucks, mcdonalds and burger king, you want single channel with a node that invested in having a lots of channels). as for the three fees you listed - yes (but not necessarily to miners?). the assumption is that you will rarely be opening and closing channels, just like you're rarely opening and closing a new debit card. you'll open with a reliable node that makes you routable, you'll once in a while deposit more funds and eventually you will close the channel. in between you can have bajillion transactions for which you will pay close to zero fees.

This is pure FUD. Satoshi himself proposed the first version of payment channels [1]. The Lightning Network paper has zero authors from Blockstream [2]. At least two other entirely independent companies are working on Lightning Network implementations [3][4]. It's well understood how trustless LN transactions work [5]. The spec [6] and code are open source, feel free to look for a "backdoor". 1. https://en.bitcoin.it/wiki/Payment_channels#Nakamoto_high-fr... 2. https://lightning.network/lightning-network-paper.pdf 3. https://github.com/lightningnetwork/lnd 4. https://github.com/ACINQ/eclair 5. https://en.bitcoin.it/wiki/Hashed_Timelock_Contracts 6. https://github.com/lightningnetwork/lightning-rfc

This repo contains specs for a lot of parts of the LN, although probably there may be changes I imagine. As for code, one of the implementations, LND (Go): https://github.com/lightningnetwork/lnd/tree/master/routing but there are at least 3 other implementations in the works. https://github.com/ElementsProject/lightning (clang) https://github.com/ACINQ/eclair (Scala) https://github.com/mit-dci/lit (Go)
