Hey there!

I owe a friend a few bucks and, since we would like to experiment with Bitcoin, he agreed to have them sent over the Lightning Network. I went to an exchange and bought 0.003 BTC, I now would like to send 0.001 BTC to him.

After reading some articles, I have probably realized that there is no use in opening a direct channel between him and me, since channels are made for recurring transactions and we are unlikely to have any in the future.

So i figured out what i need instead to do is:
- open a channel to a "famous" well connected node and fund 0.001 BTC into it
- have such "famous" node open a channel to my friend and fund the same amount into it
- finally send the LN payment to my friend, routing through such node

As a result, we will both end up with a channel opened with that node, me having a 0.001 inbound capacity, and him having 0.001 spending capacity, that we will be able to use in the future to send/receive to/from anyone connected to that node.

Is this correct? If yes, how can I accomplish it in practice?

Hi there!

I have installed the Bitcoin client for Linux (bitcoin-qt).

I have started it, and it started synchronizing blocks. After a while, my disk got full.

I have then moved the ~/.bitcoin/blocks and ~/.bitcoin/chainstate to a different partition and created symlinks. The client started again and downloaded blocks for some hours, then also that partition got full.

I have a NAS mounted via cifs (smbfs) with huge disk space. If I move the blocks and chainstate folders there and symlink them, exactly in the same way i did with the other partition, I get an error opening blocks database. It asks me if I want to rebuild it. If I answer yes, it then says the same error again and exits.

Any ideas?

Thank you
