Can I send BTC from other node or wallet with my address?

I’m trying to send bitcoins from node2 with my address using private key noted that my address is created in node1.I followed this link:
https://en.bitcoin.it/wiki/How_to_import_private_keys
I dump private key in node1 using this command:

bitcoin-cli -testnet -rpcuser=test -rpcpassword=test123 dumpprivkey "2N7YvA6ZBjFvXE3wuNQH4csev1QUWtrzYgA"

Then I imported private key in node2 through this command:

bitcoin-cli -testnet -rpcuser=test -rpcpassword=test123 importprivkey cNKbGVQvQgJsJuRy25ggZ71BRA9UZyEPCMekdntnZDWjYTg9TpRu

now I want to send bitcoin from node2 with my address to different address

can anyone please give me solution to make transaction using my address private key

Can you recover seed words with passphrase on bitcoin node?

I have a btc node (Bitcoin Core version v0.17.0.1 (64-bit))running on my Windows 10 computer, as part of regular backup I have realized I don’t have the seed words but I do have the passphrase. It has a zero balance, wallet.dat is backed up – is there a way to recover the seed words in this scenario? I’m never going to use a Windows node to store any significant amount of coin, but I’d still like to know what my options are.

From Edge to Poloniex

Bought bitcoin and have a balance in a exchange account at Poloniex. Is there another step I need to take or is this where the estimated value that changes is where I will be able to send this back to Edge, and change back to USD.
I guess my question is: Is this money at work for me here or do I need to do something else.
And is this deposit safe where it is or is there a layer of security that needs to be taken.
Obvious to say I’m new to this and also thank you for your help!!

After a long connection to the wallet, it offers to reinstall blocks and synchronize all Bitcoin core blocks

1)I installed bitcoin core on an ssd drive. Some time did not include it, a month after the inclusion of bitcoin core when you start the application with ssd asks to re-download all the blocks, the path is correct , and the folder has already downloaded the blocks. I don’t understand, my old wallet can’t download or wants to download the resulting blocks while offline. Please help to understand. 2) If I installed a portable ssd drive I can connect it to any device and use the wallet and funds on it? In such an attempt, it requires downloading blocks againenter image description here

Is it possible to run two Lightning Network nodes on top of single Bitcoin Core node?

I would like to simultaneously run LND and Eclair nodes on top of single Bitcoin Core bitcoind node. Is it possible? I wasn’t been able to pull it off so far.

If possible, how to set up ZMQ and listen-tcp?


Thanks Rene, I have managed to do it. Works flawlessly. 🙂

Listen addresses must be different, eg. 0.0.0.0:9735 and 0.0.0.0:9736, and both need to be open in router. Also rpclisten must be different, eg: 127.0.0.1:10009 and 127.0.0.1:10019

When opening channel between them use localhost address, eg. 03di28did92d2dh92d29d229d299239r98398r@127.0.0.1:9736

Electrum 3.3.2 the transaction was rejected by network rules dust error…. Tried different nodes, Doesnt Work

I’m getting the an electrum 3.3.2 error with something to do with dust.

the transaction was rejected by network rules dust error

I’m using the cli to send out a transaction and its just using 1 input and 1 output only. And the fee is auto set. It was working fine yesterday. I read it’s something to do with the node. But what is wrong with it? I tried many other public nodes and it says the same error. What is happening? An attack?

What solutions are there for something like this? My application depends on having electrum working at all times.
