What are the required settings in the bitcoin configuration file to run a BU node?

Hello all, hope you are well.
I know the abstract concepts between a node and a miner - and I'm running this on my old laptop, so I want to run a node, as opposed to a miner. However, I'm not 100% sure how to do that.
I've downloaded, compiled and started running bitcoind (unlimited) as a systemd service. ATM I'm at ~50G of the blockchain downloaded However, I don't see any settings in the configuration file that would specify "I want to attempt to create blocks" vs "I want to just act as a full node". If I correctly understand what I've read, the mining software is separate from the node software, so what I downloaded will (and can) only allow me to act as a node. Is this indeed the case?
Also, are there any extra settings in the configuration file to set in order to signal for BU? I believe that there are. If so, are they the four listed in the ViaBTC article?

Bitcoin core configuration in Windows

I've installed Bitcoin Core on Windows with the installer. I don't know how to increase the number of connections. Currently, it's always 8.
Several sources on the internet claim that custom configuration belong to a bitcoin.conf in the AppData/Bitcoin directory. But that doesn't work for me. I tried. In fact, I found out that the configuration including the datadir is currently contained in the registry. Not a single source I could found tells me that the registry contains these config values, so I'm kinda bummed out by this.
In any case, does that mean that I have to add a config value in the registry? And if so, how? The config names are different, namely, the registry config names are in camel case, while the names in bitcoin.conf are like "maxconnections=150". Help!
Edit: I consider the possibility that using the bitcoin.conf actually works and I made a mistake.
Edit2: Only 8 outgoing connections are possible (without addnode), so I opened the firewall as suggested.
Edit3: I finally get incoming connections. It's still slow but I'm optimistic that the speed will increase. It almost feels like synching an Ethereum node ffs.
Edit4: After having had 16 peers at some point yesterday, I'm back to 8 peers and no incoming connections. Speed is 1.3% per hour.
Edit5: I'm under the impression that I simply underestimated the size of the blockchain. I'm used to download huge files within minutes but 200gb is certainly something else. My bandwidth doesn't seem to be used to its full extent but it spikes up to the maximum throughput from time to time, so I guess this is the limiting factor after all. And some people want even larger blocks? F*** that.

Is anybody else here interested in Bitcoin or Bitcoin mining? I recently re-configured my mining op and was wondering if anybody else was up to anything fun. Forgive the wiring - I need to pick up some cable ties tomorrow.

Chinese stress test BCH, best they can do is 11mb / 59,000 tx, test proves that Bitcoin.com can't even configure their miners correctly.

Stress test started at block 598314 - https://blockchair.com/bitcoin-cash/block/598314
Looks to have ended at block 598423 - https://blockchair.com/bitcoin-cash/block/598423
The results are interesting, most nodes are limited to 1mb or 2mb as they're not configured correctly which is why there's so many 1029kb and 1999kb blocks. This is what you get when you have temporary profit seeking miners only looking to get the block reward rather than the transaction fees.
Bitcoin.com were one of these pools, they can't even configure their own miners properly, this test showed just how amateurish their whole operation is.
BTC.com mined the largest block #598412 https://blockchair.com/bitcoin-cash/block/598412 with 59,052 tx and a maximum of 11.4mb.

How to set up a Bitcoin full node on Linux VPS (pruning node)

This tutorial is for Linux Debian based OS (Ubuntu) at least with 1GB of RAM and 20 GB SSD. There are a few guides out there about how to set it up..but still not good enough. My Bitcoin Segwit node now is running on my VPS (yes I know it's not the best option but still..) I found few articles.. Due to these articles I’ve kept the below quite brief.
Please note: Before you start.. Your server may still be finishing installing and booting up during the first few minutes of activation. In this tutorial i'm using Linux Ubuntu 16.04 x64 LTS.
Secure VPS server (Firewall rules)
Command may disrupt existing SSH connection. Proceed with operation (y|n) ? Type y and hit ENTER.
Install the Bitcoin Core daemon (bitcoind)
Press ENTER to continue
Do you want to continue? Type y and hit enter.
Create a Bitcoin user
Enter new UNIX password (whatever you want) and then it will ask for your full name, room number, work phone, home phone, other (press the Enter key to skip). Is the information correct? Type y and hit ENTER.
Set up log rotation
Enter into it:
Press CTRL+X (if you are using nano editor) and then it will say something like this - Save modified buffer (ANSWERING "No" WILL DESTROY CHANGES) ? Type y and hit ENTER.
Configure Bitcoin
Add to the file:
prune=550
Press CTRL+X (if you are using nano editor) and then it will say something like this - Save modified buffer (ANSWERING "No" WILL DESTROY CHANGES) ? Type y and hit ENTER.
Press CTRL+D to log out of the Bitcoin
Configure swap space
The node we created only has 1GB so we’ll make some spare “virtual memory” using swap space.
Add this line at the end of the file:
Press CTRL+X (if you are using nano editor) and then it will say something like this - Save modified buffer (ANSWERING "No" WILL DESTROY CHANGES) ? Type y and hit ENTER.
Set up the Bitcoin daemon to auto-run.
Enter into it (copy paste this):
Press CTRL+X (if you are using nano editor) and then it will say something like this - Save modified buffer (ANSWERING "No" WILL DESTROY CHANGES) ? Type y and hit ENTER.
Reload systemd and start bitcoind:
You can use https://bitnodes.21.co/nodes/ to check if your node is running! If there is something wrong, please let me know that. I'm still learning ;)

Keep your Bitcoin Core UASF node up to date

Note to folks with a fake uacomment: that neither helps nor works. Upgrade to BIP148!
Those who want to use BIP148 have two main choices: UASF BIP148 and Bitcoin Knots. The first has bip148 enabled by default. The second follows a PR originally proposed to Bitcoin Core (and rejected) which adds bip148=0 (option, disabled by default) so it needs to be enabled in configuration file or at runtime.
Make a backup of your wallet.dat, just in case.

Bitcoin Core SegWit UASF BIP148

This is the "original" BIP148 version.
1) Get the source at https://github.com/UASF/bitcoin/releases.
Current release: v1.0 - https://github.com/UASF/bitcoin/releases/tag/v0.14.2-uasfsegwit1.0
As a reminder, your install options are as follows:
a) Binaries: Bitcoin Core v0.14.2-based UASF SegWit BIP148 can be downloaded here (decompress and then run desired binary (bitcoind for daemon/server, bitcoin-cli for the CLI, etc.) which you can find in bin subdirectory; there's also a PPA for Ubuntu users who prefer apt-get install).
b) Source: get the source at the URL at the top. Build as usual, following official Bitcoin Core instructions.
To install, stop and (if you want) remove existing Bitcoin Core. Then install and run Bitcoin SegWit UASF BIP148. Windows users who use installer (filenames that end with *setup-unsigned.exe) should first uninstall existing Bitcoin Core before they install this version.
How to verify binaries (signatures):
https://np.reddit.com/Bitcoin/comments/6c5zw3/howto_verify_the_signed_uasf_released_binaries/
You can also verify checksums by importing Luke's PGP key and ensuring checksums in SHA256SUMS.asc(example here) match those of the downloaded file(s).

Bitcoin Knots

This is Luke-Jr's Bitcoin release with many enhancements and a BIP148 option. You can find more at https://bitcoinknots.org.
Get it at bitcoinknots.org. Install procedure for binaries is the same as for UASF BIP148 binaries, but with one added step:
Windows users who use installer (filenames that end with *setup-unsigned.exe) need to first uninstall existing Bitcoin Core before they can install this version.
If you want to build from the source, refer to Bitcoin Knots documentation (because it has a number of different options compared to Bitcoin Core).
How to verify binaries (signatures): download and import Luke's PGP key, refresh PGP keys, then verify the signed checksums file corresponds to the checksum of the binary you downloaded for your system.

Updating installed binaries

If you're updating either UASF BIP148 or Knots binaries (which you downloaded as zip or tgz file and decompressed to your disk), stop Bitcoin, decompress newer binaries over old binaries, then start service again. You can also move old binaries and then deploy the latest binaries.

Reverting to Bitcoin Core

Before chain split

Prior to chain split (such as before Aug 1), you can "go back" by simply removing BIP148 or Knots and installing Bitcoin Core 0.14.2. You can't go back to an earlier release such as 0.12 (same behavior as with Bitcoin Core).
Starting with UASF BIP148 v1.0, however, there's less need to be concerned about going back to Bitcoin Core - as mentioned above, Bitcoin Core 0.14.2 behavior can be achieved by restarting UASF BIP148 v1.0 or Bitcoin Knots with bitp148=0.
Should you want to remove UASF BIP148-compatible and run Bitcoin Core 0.14.2, you can do this:
Then install Bitcoin Core 0.14.2.

In the case of a chain split

Please remember to pay special attention to wallet.dat if you use one. This section only deals with the change of the binary and blockchain rewind, and not coin splitting and wallet backups.
If chains splits on or after August 1st, you would have to rewind the blockchain in order to use a different Bitcoin release on another chain. Details will vary depending on the circumstances (for example, we can't know in advance which chains will exist.)
UASF BIP148 v1.0 (not older releases) makes it possible to set bip148=0 and restart which automatically rewinds the blockchain to be consistent with Core. If you wanted to change to Bitcoin Core, you could first restart UASF BIP148 or Knots with bip148=0 to rewind the blockchain, then uninstall the binaries and install Bitcoin Core.
If a chain split happens, check UASFGuide.com or this subreddit for specific details.

Be back in late July!

In the second half of July, check for updates on a weekly basis. There may be further updates or improvements.

Changelog

2017-07-12 - reminder to pay attention to wallet backup in case of changing the binaries or startup options after a chain split
2017-07-11 - download links updated for v1.0, added about auto-rewind in v1.0, other small edits
Edit: this post may be updated prior to August 1st.

Simplified explanation for setting up a UASF Full Node on your Raspberry Pi 3.

I decided to undertake an effort to run a full node on my Raspberry Pi. I followed this tutorial, but still found it was too detailed/complicated, so I reduced it down to the basic steps needed to make it happen.
This tutorial will install the UASF binaries to enforce BIP148 on August 1st. Don't be fooled thinking that the recent Barry Silbert agreement has resolved the ongoing scaling issue. Activating Segwit is necessary and UASF is the way to make that happen. Your support is needed.
This tutorial assumes that you are running Raspian, your RaspPi has internet connectivity, you have an external USB hard drive connected formatted as FAT32 and your Linux username is "pi".
IMPORTANT: For your security, you should change your username to something different than "pi" (also choose a strong password. As you will see below, you should enable UPnP or port forward 8333 on your router to your Raspberry Pi, but this creates a security risk.
These instructions will install Bitcoin Core without wallet functionality.
Create a directory that will act as a mount point for the USB drive:
[email protected]~$ mkdir ~/bitcoinData 
With your USB drive connected, run this command to confirm that your drive is recognized as /dev/sd1:
[email protected]~$ sudo blkid 
In order to tell your Raspberry Pi to mount your USB drive automatically so that anything we put in the bitcoinData directory will be going onto the USB drive we need to edit the /etc/fstab file:
[email protected]~$ sudo nano /etc/fstab 
Add the following line to the fstab file. The following assumes that the drive was /dev/sd1:
/dev/sda1 /home/pi/bitcoinData vfat uid=pi,gid=pi,umask=0022,sync,auto,nosuid,rw,nouser 0 0 
Save the fstab file and reboot. When re-started, navigate with the File Manager to /home/pi/bitcoinData and make sure the folder size corresponds to the approximate size of your external drive. This is important, otherwise, the blockchain will be saved to the micro SD card. Unless your card is 256GB, it won't fit.
Enlarge the swap file, by editing the dphys-swapfile:
[email protected]~/bin/bitcoin$ sudo nano /etc/dphys-swapfile 
Change "CONF_SWAPSIZE=100" to "CONF_SWAPSIZE=1000". Save the file, then exit. Now run:
[email protected]~$ sudo dphys-swapfile setup [email protected]~$ sudo dphys-swapfile swapon 
Update your Raspbian:
[email protected]~$ sudo apt-get update [email protected]~$ sudo apt-get upgrade -y 
Install some packages:
[email protected]~$ sudo apt-get install autoconf libevent-dev libtool libssl-dev libboost-all-dev libminiupnpc-dev -y [email protected]~$ sudo apt-get install qt4-dev-tools libprotobuf-dev protobuf-compiler libqrencode-dev -y 
Make a directory and change to that directory:
[email protected]~$ mkdir ~/bin [email protected]~$ cd ~/bin 
Install Bitcoin:
[email protected]~/bin$ git clone https://github.com/UASF/bitcoin.git -b 0.14-BIP148 [email protected]~/bin$ cd bitcoin/ [email protected]~/bin/bitcoin$ ./autogen.sh [email protected]~/bin/bitcoin$ ./configure --enable-upnp-default --disable-wallet [email protected]~/bin/bitcoin$ make -j2 
It will take about 2 hours for the "make -j2" to finish. Once done, run:
[email protected]~/bin/bitcoin$ sudo make install 
Now, create a bitcoin.conf file:
[email protected]~/bin/bitcoin$ cd ~/bitcoinData [email protected]~/bitcoinData$ nano bitcoin.conf 
Let's run this bad boy:
[email protected]~$ bitcoin-qt 
On the first start, choose the blockchain data directory as "/home/pi/bitcoinData". Expect that it will take 2 to 3 weeks to fully sync the blockchain.
The step that includes "enable-upnp-default" is intended to open the necessary port (8333) in your router. Either way, you may want to consider port-forwarding port 8333 to your Pi.
You should now go to https://bitnodes.21.co/ and click the ‘CHECK NODE’ button to see how your node appears to other nodes on the network. This is important as it lets your node contribute to the network and adds to the UASF support on node statistics.
Enjoy!

Cryoniks, Inc. - Lets Talk FrostBit^TM

Dear "everyone",
First of all, we'd like to thank the reddit community for reaching out to us to help clear up a few misconceptions and hopefully answer a few of the questions that seem to be causing a lot of confusion; we sincerely apologize for any inconveniences our launch may have caused - it was definitely not our intention. We'd also like to apologize to the editors and talented staff at TechCrunch for the negativity they were exposed to on our account. We're deeply sorry and extremely appreciative of the opportunity they so kindly granted us. Also, please pardon in-advance the length of this post - we have a lot of questions to answer!
Instead of taking a defensive approach, we thought we might take this time to share a few key features of our tech that has rightfully (unintentionally) provoked or confused quite a large number of people - we should have addressed these questions directly on our site and we deeply apologize.
The FrostBitTM Bitmining Solution does in fact generate liquid nitrogen. This feat is accomplished in 3 steps:
This three-phase cycle is continuously looped during functioning operation taking full advantage of the already pre-chilled conditions of expended liquid nitrogen. A thermally insulating foam is injected into every unit after assembly to help minimize heat-exchange during this looping process. A lot of people were curious as to why we would use a thermally insulating foam on a compressor; it has the wonderful added benefit of dampening sound levels within the unit aside from keeping everything nice and insulated.
Another key feature of our unit is our custom-designed ASIC processors designed to run at much lower temperatures. Though we have not yet made the "processor" operating temperatures public, we will divulge however that we use a slightly modified EB lithographic process to manufacture our chips using select high-temperature superconductive materials. Our fabrication process is very similar to current processes used in the production of high-grade CMOS sensors and chipsets. The advantages are three-fold: less energy consumption, higher clock-rates, and most importantly; minimal heat exchange.
As a material nears or reaches the point of superconductivity, electrical resistance within the material reaches a sweet-spot of "almost-zero" resistance. This phenomenon is well documented and enables our ASIC processors to release less heat and run at much faster and energy efficient operating conditions than typical ASIC processors (chipsets for those cringing at the word processors). Less energy is wasted while achieving much higher cycle-times. We have coined our designs the ASIC+ Cryonic ArchitectureTM
Typical processors found in high-end home PC's and GPU's do benefit greatly from low-temperature operating conditions. These however contain materials that are not designed to undergo cryonic operating conditions and will fail at eventually at material-specific temperatures. ASIC processors currently on the market also suffer from this phenomenon and are useless in a cryonic environment.
A lot of criticism has been dealt over our elected use of the customizable light-strips. We understand the this may have been slightly misleading on our behalf - our light-strips are designed to run under 2.2W of power on the highest setting. We employ a similar technology to those found on e-Reader devices to disperse light "on the surface" making maximum use of the available visible LED light produced. (Not sure about everyone else but we really love our light-strips!)
Additionally, heavy criticism for a service yet-to-be announced will now officially be clarified (again, our sincerest apologies for not making this abundantly more clear on our website ; the FrostBitTM 3D upgrade will require software and hardware modifications. We strive to take our technology to higher levels of scalability and thought our customers might appreciate the option to modify their already pricy units to do various other resource-intensive tasks. As the vast-majority of the unit expense is in providing the unique cooling system, we wanted to offer pre-existing customers a cost-effective solution to attain the same stunning results our Bitcoin configurations achieve and apply them to other domains that will benefit from our cooling technology. Additional updates as to this upgrade will be officially posted when available.
With respect to power consumption and required power infrastructure; we feel confident that consumers are well-aware that pre-existing infrastructure already exists to power many-a-household appliance in-use by the majority of our target demographic; if you can power an electric stove-top or a washing machine, you're already covered. Additional information may be found with the provided User Manual and the Safety & Maintenance Guide provided with every purchase.
Thank you to everyone that has shown us support over the last few days - we sincerely appreciate it and hope to surpass your expectations by continuing to provide you with unique products designed to run smarter, cleaner, and with unparalleled performance (and look good doing it too!). And though we can't morally call out any of our "competitors" for their obvious mishaps and false-promises - we humbly request that we be given the opportunity to establish our presence and gain your collective trust by delivering on our promises promptly and transparently unlike the many disappointments that have sadly, come before us.
If anyone has any additional questions, concerns, requests, or would like more information; kindly drop us a line at your convenience by visiting us at cryoniks.com and contacting Support.
Thank you all, it's been an absolute pleasure; Chris Whiting - Lead Project Manager, BitFrostTM

Is it safe to allow connections on port 8333 ?

Hi,
I've just built a bitcoin core node with electrs and tor, on a spare dedicated machine. All seems good and I can connect a wallet from another machine running on the same network to the node.
However, I couldn't see my node from bitnodes.io so I then tested port 8333 from canyouseeme.org but it said "connection refused".
After lots of research, I thought it must be something wrong with iptables and tried loads of different configs, but nothing helped.
I then found these:
  1. https://askubuntu.com/questions/166068/port-seems-to-be-open-but-connection-refused
  2. https://serverfault.com/questions/78048/whats-the-difference-between-ip-address-0-0-0-0-and-127-0-0-1
  3. https://bitcoin.stackexchange.com/questions/90964/my-full-node-seems-to-be-rejecting-tor-connections
Which led me to update bitcoin.conf by changing bind=127.0.0.1 to bind=0.0.0.0, tested again and it's working inasmuch as the port can be seen (from canyouseeme.org) and I think my core node is accepting incoming connections (which I think is what you're supposed to allow - right?).
I (also think I) understand that bind=127.0.0.1 (in bitcoin.conf) is only allowing traffic from localhost and that by changing it to 0.0.0.0 is akin to wildcarding it to accept any IP, is that right?
Would appreciate someone setting me straight on this.
Cheers.

I decided to undertake an effort to run a full node on my Raspberry Pi. I followed this tutorial, but still found it was too detailed/complicated, so I reduced it down to the basic steps needed to make it happen.
This tutorial will install the UASF 1.0 binaries to enforce BIP148 on August 1st.

Let's run this bad boy:

On the first start, choose the blockchain data directory as "/home/pi/bitcoinData". Expect that it will take 2 to 3 weeks to fully sync the blockchain.
The step that includes "enable-upnp-default" is intended to open the necessary port (8333) in your router. Either way, you may want to consider port-forwarding port 8333 to your Pi.
You should now go to https://bitnodes.21.co/ and click the ‘CHECK NODE’ button to see how your node appears to other nodes on the network. This is important as it lets your node contribute to the network and adds to the UASF support on node statistics.

Simplified explanation for setting up a Bitcoin 0.15 Full Node on your Raspberry Pi 3.

I decided to undertake an effort to run a full node on my Raspberry Pi. I followed this tutorial, but still found it was too detailed/complicated, so I reduced it down to the basic steps needed to make it happen.
This tutorial assumes that you are running Raspian, your RaspPi has internet connectivity, you have an external USB hard drive connected formatted as FAT32 and your Linux username is "pi".
IMPORTANT: For your security, you should change your username to something different than "pi" (also choose a strong password. As you will see below, you should enable UPnP or port forward 8333 on your router to your Raspberry Pi, but this creates a security risk.
These instructions will install Bitcoin Core without wallet functionality.
Create a directory that will act as a mount point for the USB drive:
[email protected]~$ mkdir ~/bitcoinData 
With your USB drive connected, run this command to confirm that your drive is recognized as /dev/sd1:
[email protected]~$ sudo blkid 
In order to tell your Raspberry Pi to mount your USB drive automatically so that anything we put in the bitcoinData directory will be going onto the USB drive we need to edit the /etc/fstab file:
[email protected]~$ sudo nano /etc/fstab 
Add the following line to the fstab file. The following assumes that the drive was /dev/sd1:
/dev/sda1 /home/pi/bitcoinData vfat uid=pi,gid=pi,umask=0022,sync,auto,nosuid,rw,nouser 0 0 
Save the fstab file and reboot.
When re-started, navigate with the File Manager to /home/pi/bitcoinData and make sure the folder size corresponds to the approximate size of your external drive. This is important, otherwise, the blockchain will be saved to the micro SD card. Unless your card is 256GB, it won't fit.
Enlarge the swap file, by editing the dphys-swapfile:
[email protected]~/bin/bitcoin$ sudo nano /etc/dphys-swapfile 
Change "CONF_SWAPSIZE=100" to "CONF_SWAPSIZE=1000". Save the file, then exit. Now run:
[email protected]~$ sudo dphys-swapfile setup [email protected]~$ sudo dphys-swapfile swapon 
Update your Raspbian:
[email protected]~$ sudo apt-get update [email protected]~$ sudo apt-get upgrade -y 
Install some packages:
[email protected]~$ sudo apt-get install autoconf libevent-dev libtool libssl-dev libboost-all-dev libminiupnpc-dev -y [email protected]~$ sudo apt-get install qt4-dev-tools libprotobuf-dev protobuf-compiler libqrencode-dev -y 
Make a directory and change to that directory:
[email protected]~$ mkdir ~/bin [email protected]~$ cd ~/bin 
Install Bitcoin:
[email protected]~/bin$ git clone https://github.com/bitcoin/bitcoin bitcoin [email protected]~/bin$ cd bitcoin/ [email protected]~/bin/bitcoin$ ./autogen.sh [email protected]~/bin/bitcoin$ ./configure --enable-upnp-default --disable-wallet [email protected]~/bin/bitcoin$ make -j2 
It will take about 2 hours for the "make -j2" to finish. Once done, run:
[email protected]~/bin/bitcoin$ sudo make install 
Now, create a bitcoin.conf file:
[email protected]~/bin/bitcoin$ cd ~/bitcoinData [email protected]~/bitcoinData$ nano bitcoin.conf 
Let's run this bad boy:
[email protected]~$ bitcoin-qt 
On the first start, choose the blockchain data directory as "/home/pi/bitcoinData". Expect that it will take 2 to 3 weeks to fully sync the blockchain.
The step that includes "enable-upnp-default" is intended to open the necessary port (8333) in your router. Either way, you may want to consider port-forwarding port 8333 to your Pi.
You should now go to https://bitnodes.21.co/ and click the ‘CHECK NODE’ button to see how your node appears to other nodes on the network. This is important as it lets your node contribute to the network and adds to the UASF support on node statistics.
