Lightning⚡ Node Mainnet

I briefly mentioned the Raspiblitz project some time ago and have recently learned a lot about the project, its functions and the Lightning network.

I had the first start with Raspiblitz on a RaspberryPi3, but at the latest since Raspiblitz has installed the BTCExplorer, the RPi3 is just too weak. When installing the necessary packages, the Pi3 hangs and can only be restarted by disconnecting the power connection.
Since another RaspberryPi4 with 4GB had been on the shopping list for a long time, it had offered to buy it now. Now my Raspiblitz runs much better and above all more stable on an RPi4.

I only ran the RaspberryPi4 with Raspiblitz for a few weeks in the mainnet to observe stability and availability. Today I switched my Raspiblitz from test to mainnet. 😁

You can find all information about my node here.

Those who are interested can connect. I am happy about every new peer and channel! 🙂

With this in mind .. Happy Lightning!

Get Blockchain

I added a new page.
There you can download the blockchain (soon) directly. The background of the whole is that Raspiblitz stops the torrents because they are hardly running or are available.

For users of the RaspberryPi3 this means in the future that they can only copy the blockchain from a PC or similar.
The RaspberryPi3 is too slow to sync and it would take weeks to finish.

For users of the RaspberryPi4 this means in the future that they can only synchronize the blockchain with the network or copy the blockchain from a PC.

Synchronizing with the RaspberryPi4 and a USB 2.0 HDD takes about 2-3 days. With a USB 3.0 or even an SSD it will be even faster.

Copying the blockchain from a PC takes 3 hours with the RaspberryPi4 and a USB 2.0 HDD.

**fix** GPT Header corruption

I had the problem with my new mainboard the Asus Rog Strix B-360F that as soon as I connected an external hard drive the PC no longer booted normally but when I started the message “GPT Header corruption has been detected, please check SATA mode setting in BIOS Setup “

Since I permanently connected my external hard drives, the constant F1 and going into the boot menu was rather annoying.

After long searching i have found the solution:

  1. Open the BIOS menu with F2 or DEL
  2. Select the “Boot” section
  3. Then click on “Boot Configuration”
  4. Then select the “Boot Sector / MBR / GPT) Recovery Policy” and select “Auto Recovery”
  5. Select the “Exit” section
  6. “Save Changes & Reset”
  7. Now the computer starts with an external hard drive connected and without an error message.

StorjNode (StorageNode)

A few weeks ago I came across the Storj project and quickly became very interested.

You can virtually rent out your free space here.

Since I have several Pi’s and about 12 TB of empty memory, the project came in very handy for me. Unfortunately it was not possible for me to register for a key there, even for weeks and with different email addresses.

I then kindly received a token from a user in a forum that I could use for myself.

My first node went online today. The setup was amazingly simple, to warm up I started with my almost 500GB SSD, should it get full I’ll switch to my 4TB HDD. Since storage space is not rewarded so much, I want to wait and see.

The node has now generated 1GB of traffic in the last 6 hours. I think it works like in other networks that a certain lifetime has to be proven before the node is really integrated into the network.

I’m looking forward to it

Hard disk standby with hd-idle under Ubuntu 18.04 Bionic [arm64]

I faced the problem today that I could not find hd-idle for arm64.
After a long search, I found what I was looking for.

You can compile the necessary version yourself or take a ready package.

What we still need is the UUID of the hard disk, which can be found with the blkid command.

Installation: (in my example for arm64) login via SSH

  1. su root
  2. cd /tmp
  3. wget
  4. sudo dpkg -i hd-idle_1.8_arm64.deb
  5. systemctl status hd-idle
  6. blkid (Find the path of the hard disk)
  7. nano /etc/default/hd-idle

HD_IDLE_OPTS=”-a /dev/disk/by-uuid/38376bu5-ca75-42be-bfa5-079b6d439bg6 -i 3600″ (3600 = Hard drive going to standbye after 60 minutes)

8. systemctl restart hd-idle

Raspiblitz ⚡ Lightning Node

I put on my first Lightning Node a few days ago.

I used the following project for this -> Raspiblitz I use my Pi but without a display.

I loaded the blockchain via torrent and synchronized the rest with my RaspberryPi4 with 4GB. Here it took about 24 hours to complete the synchronization. After that I moved the whole thing on my Pi3. I can only guess the synchronization with a RaspberryPi 4 or the like. perform. On a Pi3 B + this takes another 10-12 days.

So far, the node has been running without errors for about 5 days, of course via TOR.
