A community dedicated to Bitcoin, the currency of the Internet. Bitcoin is a distributed, worldwide, decentralized digital money. Bitcoins are issued and managed without any central authority whatsoever: there is no government, company, or bank in charge of Bitcoin. You might be interested in Bitcoin if you like cryptography, distributed peer-to-peer systems, or economics. A large percentage of Bitcoin enthusiasts are libertarians, though people of all political philosophies are welcome.
Hello all, not sure if this is the right sub for this type of question. I am currently working on a bitcoin development project, and I was wondering if it is possible to have one downloaded blockchain span across multiple bitcoin nodes. For example, the blockchain could be stored on a NAS, and the servers could all fetch from that blockchain?
bitcoin daemon service gets stuck in the command-line
I modified bitcoin.service like follows
# It is not recommended to modify this file in-place, because it will # be overwritten during package upgrades. If you want to add further # options or overwrite existing ones then use # $ systemctl edit bitcoind.service # See "man systemd.service" for details. # Note that almost all daemon options could be specified in # /etc/bitcoin/bitcoin.conf [Unit] Description=Bitcoin daemon After=network.target [Service] ExecStart=/usbin/bitcoind -daemon -datadir=/home/deploy/.bitcoin -conf=/home/deploy/.bitcoin/bitcoin.conf -pid=/run/bitcoind.pid # Creates /run/bitcoind owned by bitcoin RuntimeDirectory=bitcoind User=deploy Group=deploy Type=forking PIDFile=/run/bitcoind.pid Restart=on-failure # Hardening measures #################### # Provide a private /tmp and /vatmp. PrivateTmp=true # Mount /usr, /boot/ and /etc read-only for the process. ProtectSystem=full # Disallow the process and all of its children to gain # new privileges through execve(). NoNewPrivileges=true # Use a new /dev namespace only populated with API pseudo devices # such as /dev/null, /dev/zero and /dev/random. PrivateDevices=true # Deny the creation of writable and executable memory mappings. # Commented out as it's not supported on Debian 8 or Ubuntu 16.04 LTS #MemoryDenyWriteExecute=true [Install] WantedBy=multi-user.target
so that the settings and data are kept under the user deploy's home directory, the only problem is that when I run the command to start the service, it gets stuck as if it wasn't running in daemon mode. Then I have to enter CTR-C to get the command prompt again.

Bitcoin daemon doesn't stop successfully when rebooting/shutting down
I've created a rc script to start and stop my Bitcoin node (cli). I can stop and restart the daemon with no problems. It's when I shutdown or restart the server is where it says it failed. Here's the rc script:
I have an ubuntu server and want to run a full bitcoin node on it. I followed the instructions from bitcoin.org and it seems that everything installed correctly, but i had it running for over 10h and syncing is still at block 0.

Hey everyone :) I've created a user interface in VB6 for Bitcoind that anyone can download and use for FREE !!! I have called it "BDUI - Bitcoin Daemon User Interface" The VB6 source code is also included in the install folder !!! I will do my best to maintain and improve BDUI as best as I can - feedback etc very much appreciated. I have a website for my projects that I am also slowly updating... Please go to - http://www.X7E.co.uk - thanks. I have done a demo / tutorial vid on my YouTube Channel that I hope will be of use also... Please go to - https://youtu.be/WJy09BjLY0k - thanks Here is a link to a pic of the main screen of BDUI - http://www.x7e.co.uk/Projects/BDUI/Pics/BDUI-1.jpg Sonix711
At its lowest common denominator, BDUI is a User Interface for Bitcoind that uses .bat files to run Bitcoin-cli commands against the local Bitcoind application and display the output information to the user in a readable and trackable format. The use of .bat files makes the application functionality highly customisable from within the application itself.
This application will show you:
If Bitcoind is running.
The current Block Count number.
The total number of connections.
The total size of the Blockchain Folder.
A history log of all of the above.
Customisable Email notifications.
A customisable launcher for Ping, Calc, Command Prompt, GetFolderSize, Service Manager, Process Explorer & BitMessage.
An inbuilt .bat File Manager for viewing and editing all application specific .bat files.
The possibilities for even more when you use the manual or TimeLoop .bat files to do even more when they run.
BDUI Install Folder: C:\X7E\BDUI
This folder ( C:\X7E\BDUI ) is hardcoded into the application as the .bat files in the BATFILES folder are required for most of the underlying functionality to work correctly. The .bat files in the BATFILES folder can all be customised within BDUI to perform various tasks as required. Please feel free to contact me about anything BDUI or Bitcoin / CryptoCurrency related... Actually, if I can help, I will always try, so feel free to contact me as required... :) This project is still being developed, so please remember that, thanks. Also, my VB knowledge is still quite basic, although I am working hard to improve it for this project and future projects... :) Comments, Question & Suggestions Welcome... Share & Share alike !!! If others hadn't shared questions, answers, and most importantly, VB code, this project and Application would not exist !!! Check out the Websites list for all the sites that I used to help create this Application !!! Thanks for using and supporting BDUI, Bitcoin & CryptoCurrencies !!! :) Sonix711
How to securely access a bitcoin daemon from a website to display data to the public?
What is the best practice when doing rpc calls to a btc daemons on a server that is supposed to display the received and processed output? Any reference to php, python or java-derivative would be fine for me. Thank you.
Hello, I have a 93 GB bootstrap.dat file in my ~/.bitcoin/ folder. I ran ./bin/bitcoind -loadblock=~/.bitcoin/bootstrap.dat The daemon stopped at block #750 and renamed bootstrap.dat to bootstrap.dat.old for some reason at this point. Also, if I do bitcoin-cli getinfo it says over 300k blocks and the number keeps increasing overtime i run the command. If I just run bitcoind -daemon without specifying the bootstrap file, nothing happens. Any idea on whats happening here? I've run bitcoind in this folder many times (took to long so i found a bootstrap.dat) but deleted the data in ~/.bitcoin/blocks to start over this time. Is there a way I can just reset bitcoind and bitcoin-cli so I can just start fresh with the bootstrap.dat? Thanks!
Note: We have migrated to a new Bitcoin daemon and as a result, all deposit addresses have changed. Deposits to old addresses will not be credited anymore. Please be sure to check your deposit address beforehand!
I set up Bitcoin XT a few days ago on a 5$ Digital Ocean server (Ubuntu 15.10 with 500 MB Ram). The node is still busy downloading and verifying the blockchain. However, according to the logs the daemon is now restarting every time after verifying a few blocks. debug.log I installed from the apt repository, and I'm currently running v0.11.0D-b504e06 (latest version in the repo). Is there something I can do about this? It seems very inefficient to restart all the time like this.

Bitcoin Core Daemon. The Bitcoin Core daemon (bitcoind) is not included in the .dmg file you may have downloaded to install Bitcoin-QT. Bitcoind, along with its support binaries, is instead included in the OS X .tar.gz file listed on the official Bitcoin Core download page. To download this file using Terminal, execute the following command: The easiest way to store your funds. Manage your money from any device 24/7 using our web wallet. Bitcoind – a daemon program that implements the Bitcoin protocol, is controlled through the command line. It is one of the main components of the Bitcoin network node software. Bitcoin software exists in two forms: a GUI application and a background application (daemon on Unix, service on Windows). bitcoind is a program that implements the Bitcoin protocol for remote procedure call (RPC) use. It is also the second Bitcoin client in the network's history. It is available under the MIT license in 32-bit and 64-bit versions for Windows, GNU/Linux-based OSes, and Mac OS X. . As part of Bitcoin Core, bitcoind has been bundled with the original client from version 0.2.6 to 0.4.9, and with ... Bitcoin Core is programmed to decide which block chain contains valid transactions. The users of Bitcoin Core only accept transactions for that block chain, making it the Bitcoin block chain that everyone else wants to use.
