Setting up lightning with bitcoin-core

I have some questions about bitcoin-core and lightning-network-daemon. I have succesfully set up a bitcoin node running on Ubuntu Server 20.04 by following this tutorial: https://bitcoin.org/en/full-node. This is my node: https://bitnodes.io/nodes/81.166.125.218-8333/ I am planning on installing lnd using bitcoind as the backend, by following this tutorial: https://github.com/lightningnetwork/lnd/blob/master/docs/INSTALL.md In this regard, I have the following questions: What is the relationship between my bitcoin-core wallet and the lnd wallet? What fee should I set to make my lnd node as profitable as possible? What other recommendations can you give to help out a bitcoin- and lnd-noob like me? Thanks in advance for…

Risks of running lightning (LND) over a pruned node [closed]

Since i don't believe this has been adequately discussed yet; (see What are the issues of running lightning daemon with pruning node? & others) What exactly are the risks of running LND over a pruned node of let's say, 50 gb, which is roughly a year worth of data. Can we: A. Access channels that are older than a year (for routing purposes), and do so in a way that is trustless? B. Accept HTLC's that are routed through channels which are older than a year? It's a bit of a rehash of #1, but what exactly would happen in…

LND doesnt create macaroons or directories

I installed lnd and got to the point of creating a wallet with "lncli create" but I get an error "unable to read macaroon path" and gives the path of where the macaroon should be. I believe when you start lnd for the first time it creates these macaroons along with some other files and folders but mine only created tls.cert tls.key logs/bitcoin/mainnet/lnd.log data/graph/mainnet/channel.db And no macaroons. Does anyone know why it would create only some of the files and folders?? Stumped! Running on Ubuntu 20

Problem with the first Initialization of my LN node, dial tcp my-external-ip:9735: connect: connection timed out

Background I was following 402 Payment Required's LN video over here (https://www.youtube.com/watch?v=q0siLF9zmWo) and everything was good so far, until the moment of the first Initialization of my LN node, I got an (dial tcp my-external-ip:9735: connect: connection timed out) error. I was starting the Initialization by the following way lnd --externalip=X.X.X.X And I've my lnd configuration file with the following attributes alias= debuglevel=debug bitcoin.active=1 bitcoin.mainnet=1 bitcoin.node=bitcoind I created the file (before) I started the Initialization. Your environment version of lnd: I don't know, I guess it's the latest version. which operating system (uname -a on *Nix): Ubuntu 18.04 version of…

How do I get credentials on the bitcoin network?

I'm setting up an LND node so I can learn about Lightning Networks. I apparently need a set of user credentials so that I can connect to the network. How do I get the credentials that I need to set this up? Is it possible for an average user who is just trying to learn about LND? Ideally I would like to connect to the main net, so that I can connect my Zap wallet to it. I have to fill in these values in the config: bitcoind.rpcuser=bitcoind_rpc_user_string bitcoind.rpcpass=bitcoind_rpc_password_string Also can someone explain these settings to me: bitcoind.zmqpubrawblock=tcp://127.0.0.1:18501 bitcoind.zmqpubrawtx=tcp://127.0.0.1:18502 Is…
