1 RPC to BTC - Exchange - How much Bitcoin (BTC) is 1 ...

[DEVELOPMENT] Bitcoind IPV4 testnet port (18332) is failing to bind

[SOLVED] Thanks for everyone that have helped!


Hello everyone, this is a development problem that I'm currently having. Since the BTC Development sub is kind of inactive and I couldn't find any rule contraty to posting about BTC Development, I'll try my luck in here as I'm hopeless already. I've posted on BTC Stack Exchange but no answers also. Please, don't get me wrong, I'm trying to solve this problem for many days now, I've looked up everywhere for this.
I'm new to Bitcoin development and I'm currently having difficulties trying to make RPC calls from a Docker Container to a Bitcoin-Core daemon running in a SSH server. I suppose that the problem may be with Firewall or closed ports, but I also do not know much about Network settings.
I'm using nbobtc/bitcoind-php package to make the RPC calls with HTTP requests, and it is running in a Docker container. I'm sure the container is functional and is not the problem.
So here's what happening: when I run bitcoind in root user (but normal also won't work) in my SSH server, the IPV4 testnet port seems to be not opened. This message goes up when I run bitcoind:
Binding RPC on address 0.0.0.0 port 18332 failed.
Here's what my bitcoin.conf looks like (I want to use testnet in here). I'm using Bitcoin-Core "subversion": "Satoshi:0.17.1".
server=1 debug=net txindex=1 testnet=1 rpcuser=userb rpcpassword=test test.rpcport=18332 # I've already tried allowing the IP these 3 ways: # rpcallowip=192.168.xx.xx # My machine's IP # rpcallowip=172.19.x.x/xx # Docker's NBOBTC container IP # rpcallowip=0.0.0.0/0 # Allowing all IP datadir=/home/bitcoin-dev/.bitcoin debuglogfile=/home/bitcoin-dev/.bitcoin/debug.log 
Here's what appears in debug.log right after I run Bitcoind:

After all that appears above, there are just "UpdateTip", "Requesting block", "received block" and "getdata" messages. (so the P2P port, 18333, works).

And here is when I netstat:

sudo netstat -nap|grep bitcoin|grep LISTEN
tcp 0 0 0.0.0.0:18333 0.0.0.0:* LISTEN 31185/bitcoind tcp6 0 0 :::18332 :::* LISTEN 31185/bitcoind tcp6 0 0 :::18333 :::* LISTEN 31185/bitcoind 
Thank you in advance!

PS: A few days ago I could make it work when running bitcoind with root user, but now even that won't solve the problem.

Step by step in staking Redd with Raspberry Pi 3

Before I start, I would like to pay complete credits to these two guys :)
https://www.reddcointalk.org/topic/2679/reddcoin-staking-via-ubuntu-mate-on-raspberry-pi-3-model-b-march-2018 (most of my steps, if not all, are from this link)
https://github.com/joroob/reddcoin/blob/mastedoc/build-arm.md
All the steps I am writing is ABSOLUTELY NECESSARY, please don't try to skip it because I did, and it doesn't work.
step 1: get a Raspberry Pi B https://www.raspberrypi.org/products/#buy-now-modal
step 2: make sure you get proper power supply 5v 2A - the Pi will mine, it will need sufficient power. Regular USB samsung charger will not work.
step 3: get proper micro SD card (SanDisk for example) 32Gb++
step 4: USB + Mouse keyboard
step 5: flash micro SD card with Ubuntu MATE
Download Ubuntu Mate image: https://ubuntu-mate.org/raspberry-pi/
Download Etcher: https://etcher.io
After finishing downloading, use Etcher to write/flash the image on micro SD card
After this, your SD card contains Ubuntu MATE OS.
step 6: Place SD Card into Raspberry Pi 3 and start it up. You should be able to see Ubuntu OS! Congrats!
step 7: Connect to wifi or internet cable (internet is better and faster)
step 8: OPTIONAL - turn off UI OS, so that things will work faster
Open XTerminal:
sudo systemctl disable lightdm.service (to turn UI off) 
in case you want to turn UI on again, run this:
sudo systemctl start lightdm.service (to turn UI on) 
step 9: install all dependencies
sudo apt-get update && sudo apt-get install git build-essential libqt4-dev libprotobuf-dev protobuf-compiler libtool autotools-dev autoconf libssl-dev libboost-all-dev wget pkg-config sudo add-apt-repository ppa:bitcoin/bitcoin sudo apt-get update sudo apt-get install db4.8 sudo apt-get install libminiupnpc-dev sudo apt-get install libqrencode-dev Reboot 
step 10: add additional RAM (sort of) in case the App need it, this is call "Create Swap file"
sudo fallocate -l 1G /swapfile sudo chmod 600 /swapfile sudo mkswap /swapfile sudo swapon /swapfile echo ‘/swapfile none swap sw 0 0’ | sudo tee -a /etc/fstab 
step 11: Build Berkeley Database
wget http://download.oracle.com/berkeley-db/db-4.8.30.NC.tar.gz tar xfvz db-4.8.30.NC.tar.gz cd db-4.8.30.NC cd build_unix ../dist/configure --enable-cxx make sudo make install 
step 11.5: Set BerkeleyDB path
export CPATH="/uslocal/BerkeleyDB.4.8/include" export LIBRARY_PATH="/uslocal/BerkeleyDB.4.8/lib" export LD_LIBRARY_PATH=/uslocal/BerkeleyDB.4.8/lib/ 
step 12: Build Reddcoin Wallet
---download source code ---- only source from joroob/reddcoin will work because some stweak was needed for ARM CPU
cd ~ git clone https://github.com/joroob/reddcoin.git 
---build reddcoin ----
cd reddcoin ./autogen.sh ./configure --with-gui=no --disable-tests cd src make sudo make install 
If you finish this, you are in a great position!!!
step 13: Create reddcoin configuration file
cd ~ mkdir .reddcoin && cd .reddcoin nano reddcoin.conf rpcuser=YOUR OWN USERNAME, YOU DONT NEED TO REMEMBER THIS, MAKE IT AS LONG AS YOU WANT rpcpassword=YOUR OWN PASS WORD, YOU DONT NEED TO REMEMBER THIS, MAKE IT AS LONG AS YOU WANT 
step 14: Use bootstrap
(At this point, you had a running reddcoin daemon, now you can start staking. But syncing the full chain takes long time.)
cd ~/.reddcoin wget https://github.com/reddcoin-project/reddcoin/releases/download/v2.0.1.2/bootstrap.dat.xz xz -d bootstrap.dat.xz 
step 15: start the reddcoin daemon service cd ~/reddcoin/src ./reddcoind -daemon
After this, you can test if the daemon is working, by perform this command: ./reddcoin-cli getblockcount
step 16: if your app is not able to sync, it is probably the firewall issue with OS, run this to allow port 45444 (used by Reddcoin) and redo step 15
sudo iptables -I INPUT 1 -i eth0 -p tcp --dport 45444 -j ACCEPT sudo iptables -A OUTPUT -p tcp --dport 45444 -j ACCEPT 
step 17: open BEER and enjoy! This is a MUST or the daemon will stop working! I am not kidding!
step 18: Actually, i forgot to mention you need to execute this command for the wallet to stake:
reddcoind walletpassphrase $yourpassword 9999999 true 
ADDITIONAL REMARKS:
From my PC: I am using putty to execute the command, winSCP to monitor the file location on raspberry.
Moving Red Coins out of exchange really a big move, start with normal wallet, don't start with this tutorial :) Ever since I move my coins out of exchange, I am free from all of the ups and downs! Really!
So guys and gals, Redd On!
UPDATE 18 Mar: my first stake has arrived after 6 days staking :)
In case you want to tip me: RaF3TeWqgTzAdnaZQffnsxS74dag13zsAY
Edit 1: Format stuff
Edit 2: Add step 18 to execute staking command.
Edit 3: In case you don't want to compile the source code, you can download my compile version here: https://github.com/hieplenet/reddcoin/releases/tag/v2.0.0.0 (but doing this, you should be aware of the risk of me changing source code for my benefit - I don't change any thing, but you should be cautious, this is the internet :) )

Ravencoin Open Developer Meeting - 1/4/2019

[14:04] Hi everyone! [14:04] :dabbitwave: [14:04] Hey Everybody! [14:04] Hello 😃 [14:04] Sorry we're getting started a bit late. [14:04] Topics: SLC Meetup (March 15th) [14:04] 👋 [14:04] Roadmap breakdown - posted to github [14:05] IPFS (integration) [14:05] greetings 👋 [14:05] So, SLC Meetup on the 15th! [14:05] Great! [14:05] Hi! [14:06] Hi all — a special thanks to the developers and congratulations on an amazing first year!!! # [14:06] <[Dev] Blondfrogs> Hello Everyone! [14:07] We have a tentative agenda with @Tron , @corby speaking. [14:08] We would like to have nice walkthrough of the Raven DevKit for the meetup. [14:08] We are planning on hosting a meetup in SLC at the Overstock building on March 15th from 6:00pm-9:00pm. It is free admission, but there is a page on meetup.com where people can rsvp so that we have a somewhat accurate headcount for food. [14:08] sup guys [14:08] hey russ [14:09] We are planning on having a few speakers and have allotted a bit of time at the end for people to meet and greet each other. [14:09] can you guys link us to the page somewhere when thats available? 😄 [14:10] free food?! [14:10] todays topic? [14:10] yeah can we indicate pepperoni pizza [14:10] Sounds good to me @Jeroz Nothing ordered yet though. 😃 [14:10] only pepperoni pizza is served at true blockchain meetings right [14:10] :blobhide: [14:10] Absolutely. The itinerary just needs to be finalized and then I'll make a broad post about the rest of the details. [14:11] https://www.meetup.com/Salt-Lake-City-salt-lake-city-Meetup/ [14:11] 😭 so far away [14:11] West Coast! [14:11] @MTarget But there's pizza, so worth the travel time. [14:11] lol [14:12] I'll be watching the stream if its available since i'm from montreal/canada 😛 [14:12] Ah yes, I love $300 pizza 😉 [14:12] as long as I get to see your smiling faces @Tron @RavencoinDev then it's worth the time [14:12] We'll be there. [14:12] We'll be messaging additional details as they get finalized. [14:12] Greeting and salutations! [14:12] sup [14:13] Hey, $300 is considerably cheaper than 2 $3,700,000 pizzas. [14:14] Ok, switching topics... [14:14] yeah its a way to fly, [14:14] question is whether those piza's will be paid for in RVN coin or not :ThinkBlack: [14:14] Roadmap [14:14] It hasn't changed, just added some detail. [14:14] https://github.com/RavenProject/Ravencoin/tree/masteroadmap [14:15] nice [14:15] This now links to a breakdown for messaging, voting, anti-spam, and rewards (dividends) [14:15] will there be any additional RPC functionality coming in the future, thinking in terms of some functions that are only available in ravencore-lib [14:15] apologies if now is not time to ask questions, i can wait for later [14:15] "Phase 7 - Compatibility Mode" - that's new 😮 [14:15] The protocol for messaging is pretty well established, but the rest isn't in stone (code) yet. [14:16] can you give us details on compatibility mode? [14:16] In broad brush strokes. [14:17] The idea is to allow ravend to act as a daemon that looks like a single coin. [14:17] so ravend that only works with the bitcoin asset? [14:18] interesting [14:19] So you start it with an option to only work with a single asset/token account or something? [14:19] hmm compelling what is the reason for this? some kind of scale or performance? [14:19] ^ [14:19] Example: Configure ravend to listen for transfer RPC call for senttoaddress or sendfrom, but for a specific asset. This would allow easy integration into existing system for assets. [14:20] Only the daemon or the whole wallet UI? [14:20] yeah thats great, rpc functions dont allow us to do this yet, if i recall [14:20] or at least we depend more on ravencore lib [14:20] so like asset zmq [14:20] that's smart [14:20] @Tron it also sounds like it makes our life easier working with RPC, instead of core all the time for some functionality [14:21] if i understand correctly anyways [14:21] So you could run numerous instances of ravend each on their own network and RPC port, each configured for a different asset. You would need some balance of RVN in each one to cover transaction fees, then. [14:21] id be curious to know what all the advantages are of this [14:21] one more question, how would i decentralize the gateway between bitcoin mainnet/ravencoin mainnet? in the current RSK implementation they use a federated gateway, how would we avoid this? [14:21] it sounds neato [14:21] Just the daemon. The alternative is to get exchanges to adapt to our RPC calls for assets. It is easier if it just looks like Bitcoin, Litecoin or RVN to them, but it is really transferring FREE_HUGS [14:22] That makes sense. Should further increased exchange adoption for each asset. [14:22] hmm yeah its just easier for wallet integration because its basically the same as rvn and bitcoin but for a specific asset [14:22] so this is in specific mind of exchange listings for assets i guess [14:23] if i understand rightly [14:23] @traysi Gut feel is to allow ravend to handle a few different assets on different threads. [14:23] Are you going to call it kawmeleon mode? [14:23] Lol [14:23] I read that as kaw-melon mode. [14:24] same lol [14:24] so in one single swoop it possible to create a specific wallet and server daemon for specific assets. great. this makes it easier for exchanges, and has some added advantages with processing data too right? [14:24] Still keeping a RVN balance in the wallet, as well, Tron. How will that work is sendtoaddress sends the token instead of the RVN? A receive-RVN/send tokens-only wallet? [14:25] @traysi Yes [14:25] sendtoaddress on the other port (non RVN port) would send the asset. [14:25] This will be a hugely useful feature. [14:25] ^ [14:26] @Tron currently rpc function not support getaddresses senttowallet and this has to be done in ravencore lib, will this change you propose improve this situation [14:26] Config might look like {"port":2222, "asset":"FREE_HUGS", "rpcuser":"hugger", "rpcpass":"gi3afja33"} [14:26] how will this work cross-chain? [14:28] @push We'd have to go through the rpc calls and work out which ones are supported in compatibility mode. Obviously the mining ones don't apply. And some are generic like getinfo. [14:28] ok cool 👍 cheers [14:29] for now we continue using ravencore lib for our plans to keep track i just wondering if better way [14:29] as we had some issue after realising no rpc function for getting addresses of people who had sent rvn [14:29] @push | ravenland.org all of the node explorer and ravencore-lib functionality is based on RPC (including the addressindex-related calls). Nothing you can't do with RPC, although I'm not sure of the use cases you're referring to.. [14:29] interesting, so ravencore lib is using getrawtransaction somehow [14:29] i thought this may be the case [14:29] that is very useful thankyou for sharing this [14:30] look into addressindex flag and related RPC calls for functions that operate on addresses outside your wallet [14:30] thank you that is very useful, tbh i am not very skilled programmer so just decoding the hex at the raven-cli commandline was a challenge, i shall look more into this, valued information thanks as this was a big ? for us [14:31] Ok, things have gone quiet. New topic. [14:31] IPFS (integration) [14:31] GO [14:33] ... [14:33] <[Dev] Blondfrogs> So, we have been adding ipfs integration into the wallet for messaging. This will allow the wallets to do some pretty sweet stuff. For instance, you will be able to create your ipfs data file for issuing an asset. Push it to ipfs from the wallet, and add the hash right into the issuance data. This is going to allow for a much more seamless flow into the app. [14:34] <[Dev] Blondfrogs> This ofcourse, will also allow for users to create messages, and post them on ipfs and be able to easily and quickly format and send messages out on the network with ipfs data. [14:34] It will also allow optional meta-data with each transaction that goes in IPFS. [14:34] will i be able to view ipfs images natively in the wallet? [14:34] <[Dev] Blondfrogs> Images no [14:34] We discussed the option to disable all IPFS integration also. [14:35] @russ (kb: russkidooski) Probably not. There's some risk to being an image viewer for ANY data. [14:35] No option in wallet to opt into image viewing? [14:35] cool so drag and drop ipfs , if someone wanted to attach an object like an image or a file they could drag drop into ui and it create hash and attach string to transaction command parameters automatically [14:35] We could probably provide a link -- with a warning. [14:35] nomore going to globalupload.io [14:35] :ThinkBlack: [14:35] I understand that the wallet will rely on globalupload.io. (phase 1). Is it not dangerous to rely on an external network? Or am I missing something? [14:36] hmm [14:36] interesting, i suppose you could hash at two different endpoints and compare them [14:36] if you were that worried [14:36] and only submit one to the chain [14:36] You will be able to configure a URL that will be used as an IPFS browser. [14:36] Oh ic [14:36] you wont flood ipfs because only one hash per unique file [14:36] <[Dev] Blondfrogs> There are multiple options for ipfs integration. We are building it so you can run your own ipfs node locally. [14:36] <[Dev] Blondfrogs> or, point it to whatever service you would like. e.g. cloudflare [14:36] this is very cool developments, great to see this [14:37] Just like the external block explorer link currently in preferences. [14:37] @[Dev] Blondfrogs what about a native ipfs swarm for ravencoin only? [14:37] We have discussed that as an option. [14:37] @push | ravenland.org Considering having a fallback of upload through globalupload.io and download through cloudflare. [14:37] <[Dev] Blondfrogs> @russ (kb: russkidooski) We talked about that, but no decisions have been made yet. [14:37] yeah, i would just use two endpoints and strcompare the hash [14:37] as long as they agree good [14:37] submit tran [14:38] else 'potentially mysterious activity' [14:38] ? [14:38] if you submitted the file to ipfs api endpoints [14:38] Will the metadata just be a form with text only fields? [14:39] and then you would get 2 hashes, from 2 independent services [14:39] that way you would not be relying on a central hash service [14:39] and have some means of checking if a returned hash value was intercepted or transformed [14:39] i was answering jeroz' question [14:40] about relying on a single api endpoint for upload ipfs object [14:40] We have also kicked around the idea of hosting our own JSON only IPFS upload/browse service. [14:41] I have a service like this that is simple using php [14:41] we only use it for images right now [14:41] but fairly easy to do [14:41] Yup [14:42] Further questions about IPFS? [14:43] contract handling? file attach handling? or just text fields to generate json? [14:44] trying to get an idea of what the wallet will offer for attaching data [14:44] Probably just text fields that meet the meta-data spec. [14:44] ok noted [14:44] What do you mean by contract handling @sull [14:45] We won't prevent other hashes from being added. [14:45] asset contract (pdf etc) hash etc [14:45] <[Dev] Blondfrogs> also, being able to load from a file [14:45] got it, thanks [14:47] Let's do some general Q&A [14:48] Maybe just a heads up or something to look for in the future but as of right now, it takes roughly 12 hours to sync up the Qt-wallet from scratch. Did a clean installation on my linux PC last night. [14:48] Any plans or discussions related to lack of privacy of asset transfers and the ability to front run when sending to an exchange? [14:48] ^ [14:48] Is there a way to apply to help moderate for example the Telegram / Discord, i spend alot of time on both places, sometimes i pm mods if needed. [14:49] Any developed plans for Asset TX fee adjustment? [14:49] also this^ [14:49] @mxL86 We just created a card on the public board to look into that. [14:49] General remark: https://raven.wiki/wiki/Development#Phase_7_-_Compatible_Mode = updated reflecting Tron's explanation. [14:49] @mxL86 That's a great question. We need to do some profiling and speed it up. I do know that the fix we added from Bitcoin (that saved our bacon) slowed things down. [14:50] Adding to @mxL86 the sync times substantially increased coinciding with the asset layer activation. Please run some internal benchmarks and see where the daemon is wasting all its cycles on each block. We should be able to handle dozens per second but it takes a couple seconds per block. [14:50] @BW__ no plans currently for zk proofs or anything if that's what you're asking [14:50] You are doing a great job. Is there a plan that all this things (IPFS) could be some day implemented in mobile wallet? Or just in QT? [14:50] i notice also that asset transactions had some effect on sync time as we were making a few. Some spikes i not analysed the io and cpu activity properly but will if there is interest [14:51] we are testing some stuff so run into things i am happy to share [14:51] @BW__ Might look at Grin and Beam to see if we can integrate Mimble Wimble -- down the road. [14:51] yeees [14:51] @J. | ravenland.org work with the telegram mods. Not something the developers handle. [14:51] i love you [14:51] @J. | ravenland.org That would be best brought up with the operators/mods of teh telegram channel. [14:51] @corby @Tron thnx [14:51] @S1LVA | GetRavencoin.org we're planning on bumping fees to... something higher! [14:51] no catastrophic failures, just some transaction too smals, and mempool issues so far, still learning [14:52] @corby i thought that this may happen :ThinkBlack: [14:52] @corby x10? 100x? 1000x? Ballpark? [14:52] Definitely ballpark. [14:52] 😃 [14:52] 😂 [14:52] Is a ballpark like a googolplex? [14:53] @push | ravenland.org asset transactions are definitely more expensive to sync [14:53] yes yes they are [14:53] they are also more expensive to make i believe [14:53] 10,000x! [14:53] as some sync process seems to occur before they are done [14:53] @traysi ★★★★★ thanks for the suggestions we are going to be looking at optimizations [14:53] But, it is way slower than we like. Going to look into it. [14:53] i do not understand fully its operation [14:53] 1000x at minimum in my opinion [14:53] its too easy to spam the network [14:54] yes there has been some reports of ahem spam lately [14:54] :blobhide: [14:54] 😉 [14:54] cough cough ravenland [14:54] @russ (kb: russkidooski) we're in agreement -- it's too low [14:54] default fee 0.001 [14:54] ^ something around here [14:54] @corby yep we all are i think [14:55] waaay too low [14:55] meaningful transactions start with meaningful capital expense [14:55] though there is another scenario , there are some larger volume, more objective rich use cases of the chain that would suffer considerably from that [14:55] just worth mentioning, as i have beeen thinking about this a lot [14:55] there are some way around, like i could add 1000 ipfs hashes to a single unique entity, i tested this and it does work [14:56] @russ (kb: russkidooski) What would you suggest. [14:57] I had a PR for fee increase and push back. [14:57] Ignore the push back. 0.001 RVN is not even a micro-farthing in fiat terms [14:57] definitely around 1000x [14:57] Vocal minority for sure [14:57] ^ yep [14:57] @russ (kb: russkidooski) That sounds reasonable. [14:57] Couple hundred Fentons [14:58] right now an asset transaction is 0.01 of a penny essentially [14:58] 1 RVN would work now, but not when RVN is over $1. [14:58] yes exactly [14:58] Hi. Late to the party. [14:58] We are also talking about a min fee. The system will auto-adapt if blocks fill up. [14:58] im thinking tron, some heavy transaction use cases would fall out of utility use if that happened [14:58] so whats the thinking there [14:59] is there a way around the problem, bulked ipfs hash transactions? [14:59] 1000x would put us around btc levels [14:59] maybe a minimum 500x? [14:59] @russ (kb: russkidooski) Agreed. [14:59] <[Dev] Blondfrogs> It is time to wrap it up here. Everyone. Thank you all for your questions and thoughts. We will be back in 2 weeks. 😃 [14:59] Small increase and review. [14:59] Thanks all! [14:59] Cheers. [15:00] yeah sorry for 1 million questions guys hope i didnt take up too much time [15:00] cheers all 👍 [15:00] Thanks everyone [15:00] Thanks everyone for participating!!! [15:00] That is what we are here for [15:00] 100x-500x increase, 1000x maximum [15:00] 🍺

Interested in contributing to the BTC network? Here is the steps to get a full node up and running in Linux.

These instructions will work both on a VPS cloud server or a personal computer. You may find cheap VPS somewhere online for rent.
What Is A Full Node?
A full node is a program that fully validates transactions and blocks. Almost all full nodes also help the network by accepting transactions and blocks from other full nodes, validating those transactions and blocks, and then relaying them to further full nodes.
Most full nodes also serve lightweight clients by allowing them to transmit their transactions to the network and by notifying them when a transaction affects their wallet. If not enough nodes perform this function, clients won’t be able to connect through the peer-to-peer network—they’ll have to use centralized services instead.
Many people and organizations volunteer to run full nodes using spare computing and bandwidth resources—but more volunteers are needed to allow Bitcoin to continue to grow. This document describes how you can help and what helping will cost you.
Costs And Warnings
Running a Bitcoin full node comes with certain costs and can expose you to certain risks. This section will explain those costs and risks so you can decide whether you’re able to help the network.
Special Cases
Miners, businesses, and privacy-conscious users rely on particular behavior from the full nodes they use, so they will often run their own full nodes and take special safety precautions. This document does not cover those precautions—it only describes running a full node to help support the Bitcoin network in general.
Please consult an expert if you need help setting up your full node correctly to handle high-value and privacy-sensitive tasks.
Secure Your Wallet
It’s possible and safe to run a full node to support the network and use its wallet to store your bitcoins, but you must take the same precautions you would when using any Bitcoin wallet. Please see the securing your wallet page for more information.
Minimum Requirements
Bitcoin Core full nodes have certain requirements. If you try running a node on weak hardware, it may work—but you’ll likely spend more time dealing with issues. If you can meet the following requirements, you’ll have an easy-to-use node.
Note: many operating systems today (Windows, Mac, and Linux) enter a low-power mode after the screensaver activates, slowing or halting network traffic. This is often the default setting on laptops and on all Mac OS X laptops and desktops. Check your screensaver settings and disable automatic “sleep” or “suspend” options to ensure you support the network whenever your computer is running.
Possible Problems
Legal: Bitcoin use is prohibited or restricted in some areas.
Bandwidth limits: Some Internet plans will charge an additional amount for any excess upload bandwidth used that isn’t included in the plan. Worse, some providers may terminate your connection without warning because of overuse. We advise that you check whether your Internet connection is subjected to such limitations and monitor your bandwidth use so that you can stop Bitcoin Core before you reach your upload limit.
Anti-virus: Several people have placed parts of known computer viruses in the Bitcoin block chain. This block chain data can’t infect your computer, but some anti-virus programs quarantine the data anyway, making it more difficult to run a full node. This problem mostly affects computers running Windows.
Attack target: People who want to disrupt the Bitcoin network may attack full nodes in ways that will affect other things you do with your computer, such as an attack that limits your available download bandwidth or an attack that prevents you from using your full node’s wallet for sending transactions.
Linux Instructions
The following instructions describe installing Bitcoin Core on Linux systems.
Ubuntu 14.10 Instructions for Bitcoin Core 0.10.0.
If you use Ubuntu Desktop, click the Ubuntu swirl icon to start the Dash and type “term” into the input box. Choose any one of the terminals listed:
Alternatively, access a console or terminal emulator using another method, such as SSH on Ubuntu Server or a terminal launcher in an alternative desktop environment.
Type the following line to add the Bitcoin Personal Package Archive (PPA) to your system:
sudo apt-add-repository ppa:bitcoin/bitcoin
You will be prompted for your user password. Provide it to continue. Afterwards, the following text will be displayed:
Stable Channel of bitcoin-qt and bitcoind for Ubuntu, and their dependencies
More info: https://launchpad.net/~bitcoin/+archive/ubuntu/bitcoin
Press [ENTER] to continue or ctrl-c to cancel adding it
Press enter to continue. The following text (with some variations) will be displayed and you will be returned to the command line prompt:
gpg: keyring /tmp/tmpixuqu73x/secring.gpg' created gpg: keyring/tmp/tmpixuqu73x/pubring.gpg' created gpg: requesting key 8842CE5E from hkp server > > > >keyserver.ubuntu.com gpg: /tmp/tmpixuqu73x/trustdb.gpg: trustdb created gpg: key 8842CE5E: public key "Launchpad PPA for Bitcoin" imported gpg: no ultimately trusted keys found gpg: Total number processed: 1 pg: imported: 1 (RSA: 1) OK
Type the following line to get the most recent list of packages:
sudo apt-get update
A large number of lines will be displayed as different update files are downloaded. This step may take several minutes on a slow Internet connection.
To continue, choose one of the following options
sudo apt-get install bitcoin-qt
sudo apt-get install bitcoind
sudo apt-get install bitcoin-qt bitcoind
After choosing what packages to install, you will be asked whether you want to proceed. Press enter to continue.
If you’re logged in as an administrative user with sudo access, you may log out. The steps in this section should be performed as the user you want to run Bitcoin Core. (If you’re an expert administrator, you can make this a locked account used only by Bitcoin Core.)
Before using the Bitcoin Core daemon, bitcoind, you need to create its configuration file with a user name and password. First create the .bitcoin directory, create (touch) the file, and set the file’s permissions so that only your user account can read it. From the terminal, type:
mkdir ~/.bitcoin touch ~/.bitcoin/bitcoin.conf chmod 600 ~/.bitcoin/bitcoin.conf
Then you can run the command bitcoind. It will print output similar to this:
bitcoind Error: To use the "-server" option, you must set a rpcpassword in the configuration file: /home/bitcoinorg/.bitcoin/bitcoin.conf It is recommended you use the following random password: rpcuser=bitcoinrpc rpcpassword=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX (you do not need to remember this password)
The username and password MUST NOT be the same.
If the file does not exist, create it with owner-readable-only file permissions. It is also recommended to set alertnotify so you are notified of problems; for example: alertnotify=echo %s | mail -s "Bitcoin Alert" [email protected] The “rpcpassword” displayed will be unique for your system. You can copy the rpcuser and rpcpassword lines into your configuration file using the following commands. Note that in most Ubuntu terminals, you need to press Ctrl-Shift-C to copy and Ctrl-Shift-V to paste because Ctrl-C and Ctrl-V have different meanings in a Unix-style terminal.
echo rpcuser=bitcoinrpc >> ~/.bitcoin/bitcoin.conf echo rpcpassword=XXXXXX >> ~/.bitcoin/bitcoin.conf (Warning: Don’t use XXXXXX as your RPC password. Copy the rpcpassword displayed by bitcoind for your system.)
Now you can start Bitcoin Core daemon for real. Type the following command:
bitcoind -daemon
It will print a message that Bitcoin Core is starting. To interact with Bitcoin Core daemon, you will use the command bitcoin-cli (Bitcoin command line interface). Note: it may take up to several minutes for Bitcoin Core to start, during which it will display the following message whenever you use bitcoin-cli:
error: {"code":-28,"message":"Verifying blocks..."}
After it starts, you may find the following commands useful for basic interaction with your node:
to safely stop your node, run the following command:
bitcoin-cli stop
A complete list of commands is available in the Bitcoin.org developer reference.
When Bitcoin Core daemon first starts, it will begin to download the block chain. This step will take at least several hours, and it may take a day or more on a slow Internet connection or with a slow computer. During the download, Bitcoin Core will use a significant part of your connection bandwidth. You can stop Bitcoin Core at any time using the stop command; it will resume from the point where it stopped the next time you start it.
Optional: Start Your Node At Boot
Starting your node automatically each time your computer boots makes it easy for you to contribute to the network. The easiest way to do this is to start Bitcoin Core daemon from your crontab. To edit your crontab, run the following command:
crontab -e
@reboot bitcoind -daemon Save the file and exit; the updated crontab file will be installed for you. Now Bitcoin Core daemon will be automatically started each time your reboot your computer.
If you’re an Ubuntu expert and want to use an init script instead, see this Upstart script.
You have now completed installing Bitcoin Core. If you have any questions, please ask in one of Bitcoin’s many communities, such as Bitcoin StackExchange, BitcoinTalk technical support, or the #bitcoin IRC chatroom on Freenode.
To support the Bitcoin network, you also need to allow incoming connections. Please read the Network Configuration section for details.
Network Configuration
If you want to support the Bitcoin network, you must allow inbound connections.
When Bitcoin Core starts, it establishes 8 outbound connections to other full nodes so it can download the latest blocks and transactions. If you just want to use your full node as a wallet, you don’t need more than these 8 connections—but if you want to support lightweight clients and other full nodes on the network, you must allow inbound connections.
Servers connected directly to the Internet usually don’t require any special configuration. You can use the testing instructions below to confirm your server-based node accepts inbound connections.
Home connections are usually filtered by a router or modem. Bitcoin Core will request your router automatically configure itself to allow inbound connections to Bitcoin’s port, port 8333. Unfortunately many routers don’t allow automatic configuration, so you must manually configure your router. You may also need to configure your firewall to allow inbound connections to port 8333. Please see the following subsections for details.
Testing Connections
The BitNodes project provides an online tool to let you test whether your node accepts inbound connections. To use it, start Bitcoin Core (either the GUI or the daemon), wait 10 minutes, and then visit the GetAddr page (https://getaddr.bitnodes.io/). The tool will attempt to guess your IP address—if the address is wrong (or blank), you will need to enter your address manually.

Add lines:
*/1 * * * * cd /path/to/explorer && /usbin/nodejs scripts/sync.js index update > /dev/null 2>&1 */2 * * * * cd /path/to/explorer && /usbin/nodejs scripts/sync.js market > /dev/null 2>&1 */5 * * * * cd /path/to/explorer && /usbin/nodejs scripts/peers.js > /dev/null 2>&1 
If the BiblePay isnt already running, run it
cd home/username/biblepay/src ./biblepayd -daemon -txindex 
If Explorer isnt already running, run it
cd home/username/explorer npm start 
Recommendation:*
Add these parameters to biblepay.conf file
daemon=1 txindex=1 
Extra: This Iquidis for Dummides guide also adds: https://gist.github.com/zeronug/5c66207c426a1d4d5c73cc872255c572
Upstart, to have MongoDB auto start after reboots
Forever, to make sure Explorer is always running
Install Forever to keep the js running # sudo npm install forever -g # sudo npm install forever-monitor Start the Explorer # forever start bin/cluster 
Nginx - Reverse Proxy Port 3001 to 80 https://eladnava.com/binding-nodejs-port-80-using-nginx/
BiblePay Daemon set to run Every 2 Minutes with Cron
sudo crontab -e */2 * * * * /home/biblepay/src/biblepayd > /dev/null 2>&1 
Note: In ~/.biblepaycore/biblepay.conf add daemon=1 and txindex=1 Note: > /dev/null 2>&1 will capture both STDOUT (1) and STDERR (2) and send them to /dev/null
Auto Remove index.pid if indexing is complete
#!/bin/bash fname="/home/biblepay/exploretmp/index.pid" if [[ -f "$fname" ]]; then pid=$( /dev/null r=$? echo $r if [ $r -eq 0 ]; then exit 1 else rm $fname fi fi 
-f is checking if the file exists index.pid is the indexing lock file with its process ID number inside of it ps -p checks if the process is running $? is the value of the last output that ran and since the previous value is going to dev/null, its the exit code status "0 for successful executions and 1 or higher for failed executions." and so if the process is still running, the bash script just exits, otherwise the process is done and the index.pid file gets removed the file doesnt need a .sh extension, if you have "#!/bin/bash" at the top then linux knows its a bash script chmod +x to set it as executable

BronyCoin ( Cryptocurrency )

This is a pre-release post to gather opinions from fellow Bronies. What do I need your opinions on? just about everything really 1) Do you agree with the amount of currency been mined yearly? 2) Do you think we can achieve better than the Doge meme community did with their currency? 3) Do you like the PoS/PoW advanced hybrid system or pure POW? 4) Do you think half the supply of Dogecoin is okay, or should we go even rarer supply with our currency? 5) Do you think merchants at Bronycon and other conventions would accept the currency as payment? 6) Would you use Bronycoin to tip your friends for art work and stuff? 7) Do you think the sub units 100 million parts that make up 1 Bronycoin, should be called Pegasisters or Bits?? 8) what do you believe is best way to insure only Bronies get free currency??? This is a mock up of this release post o_O note no download links or source till we're ready, but if you wish to test a crypto wallet to see what the competition has, Id say try Dogecoin as that's the currency we'll be looking to take over in market share. Bronycoin (BRO) like with the satoshi parts in a Bitcoin, the 100 million parts that make up each Bronycoin will be called Bits, Bits for short :) so 100 million Bits = 1 Bronycoin (Brony) Why Bronycoin? Because first of all, we don't like central banks and corrupt governments, and would love to see them lose the monopoly, Why shouldn't Bronies create and control our own currency? Bronycoin's goal is to be used for tipping other Bronies for Artwork and Fun on forums, social networks, darknets like I2P, Tor and others, as well as the normal Internet (clearnet) At the current moment it works with SOCKS over I2P/Tor. Native support for I2P should be in place soon. Its an advanced NeoScrypt PoW/PoS coin, and has some other nice features too. Such as transaction messaging and been (Turning complete) But the main feature is the large community of Bronies, something Doge could only dream of :eek: why should doge go down as the greatest meme in history just because somebody made a cryptocurrency of it??? Bronies create more memes daily than any dogers. Proof-Of-Stake Bronycoin's major distinguishing feature is that it uses proof-of-stake/proof-of-work hybrid system. The proof-of-stake system was designed to address vulnerabilities that could occur in a pure proof-of-work system. For example, there is a risk of 51% attacks in Bitcoin or Litecoin and Dogecoin resulting from a monopoly on mining power (a 51% attack is when a single entity possesses over a half of the network hash power), which would possibly allow this entity to double spend coins. With a proof-of-stake system, a network attacker would also need to gain a large quantity of coins. This has the effect of making a monopoly more costly, and stops the risk of a monopoly from proof-of-work mining shares. Digital money made for the Internet Bronycoin was born from the Internet, bringing the freedom of physical money to the virtual world, while making payments easier and more secure in both worlds. Bronycoin can offer an alternative to previous cumbersome and costly systems, and it can increase online business access to developing countries, as well as helping to advance open source freedom, and the Brony community world wide. SPECIFICATIONS Advanced hybrid proof-of-work (PoW) and proof-of-stake (PoS) 50 billion coins to be produced block hashing is BLAKE2s PoW hashing is NeoScrypt PoS hashing is SHA-256d 1 minute combined block target (3 minutes for PoW, 1.5 minutes for PoS) Re targets every block Time warp and instamining protection Advanced check pointing against 51% attacks Transaction messaging supported 6 confirmations for regular transactions 200 confirmations for minted coins Very low transaction fees (most transactions are free) No destruction of transaction fees (all collected by a block finder) The default P2P port is 15298, RPC port is 15299 I2P/Tor ready POS INFORMATION PoW and PoS blocks carry the same fixed reward of 5 Brony one of the 1st implementation of a fixed PoS block rewards STATS / RANKINGS http://coinmarketcap.com/all.html http://www.whattomine.com/ not on sites yet.

INCAKOIN. Creating a SAFE and environmentally sound future for the children of the world :D
Many newcomers and some of the early adopters might be asking themselves “Why INCAKOIN? Whats so special about incakoin?”….. Well I’ll tell you.
1.) Early adoption.
INCAKOIN is rounding post beta. INCAKOIN’S dev’s have worked out the bugs. INCA survived a 51% attack which we are very proud of doing. Checkpoint servers have been installed. What this means is even IF incakoin were to experience a 51% attack developers can rewind the blockchain ( The platform in which carries out transactions on the network. ) back to the time of attack and recommence mining right before the time of the attack. A fix for the malleability issue bitcoin has been facing. CRUCIAL due to the rouge nature of data mining. The server acts as a SAFEGUARD so that no one group or entity can control the blockchain or all the coin supply. This is a very good thing and is unique to INCAKOIN.. The Proof of Stake give’s INCA the ability to verify transactions and new coin creation with older mature coins. Another fix for the transaction malleability exploit facing previous forms of CryptoCurrencies. Genius if you ask me. Good work DEV’s. Most SECURE CryptoCurrency. Making us MORE secure than Bitcoin by LIGHT YEARS :D
2.) Fair supply
We came into the game with the question “Why would 21 Million of something be fair for a GLOBAL economy?” Answer: It wouldn’t. Bitcoin is not a fairly distributed currency. 21 million units divisible by how ever many times it can be divided will still NOT be fairly distributed currency. Especially with Bitcoin early adopters holding many of the coins already. Its like saying “I have money because I’m SMARTER than you. I had INVESTED when you didn’t know and I didn’t bother to TELL YOU because it was INSIDE information”…. If this was Wall Street bitcoin would be Enron. Its unforgivable. INCAKOIN however is very transparent about its activities. We feel as though that withholding information about us or how we operate is not something we are willing to do. That’s why we remain transparent. Keeps us honest. 190 million INCA coins are a very reasonable number as far as supply of digital gold. This number better reflects the worlds supply of gold if we choose for it to be the basis of our backing. The network is setup for rapid growth and hashrate. So jump right in and mine with us. You’ll make a FORTUNE :D
3.) Because we CARE :)
We care about the world and people. INCAKOIN is friendly to the environment. With our model of mining we use way less electricity and we do so with pride. Being a Hybrid Proof of Stake and Proof of Work coin enables us to use way less electricity than the BEAST that Bitcoin has become. It is our obligation as responsible adults to create a future that we would want our children and our children’s children to grow up in when we are gone. To do anything else would be SELFISH! We encourage everyone who mines INCAKOIN to be as eco friendly as possible. Solar, Wind, and Water powered energy if you have the means.
On that note that’s what make us special. INCAKOIN is advanced and a hybrid of CryptoCurrency. We have the fix already in place that Bitcoin lacks concerning transaction malleability. We are the future and the future is made of INCA gold.

Interested in contributing to the BTC community? Here is a exhaustive manual to get you up and running. (Only takes about 20-30 minutes if you are fluent in command prompt on linux).

These instructions will work both on a VPS cloud server or a personal computer. You may find cheap VPS somewhere online for rent.
What Is A Full Node?
A full node is a program that fully validates transactions and blocks. Almost all full nodes also help the network by accepting transactions and blocks from other full nodes, validating those transactions and blocks, and then relaying them to further full nodes.
Most full nodes also serve lightweight clients by allowing them to transmit their transactions to the network and by notifying them when a transaction affects their wallet. If not enough nodes perform this function, clients won’t be able to connect through the peer-to-peer network—they’ll have to use centralized services instead.
Many people and organizations volunteer to run full nodes using spare computing and bandwidth resources—but more volunteers are needed to allow Bitcoin to continue to grow. This document describes how you can help and what helping will cost you.
Costs And Warnings
Running a Bitcoin full node comes with certain costs and can expose you to certain risks. This section will explain those costs and risks so you can decide whether you’re able to help the network.
Special Cases
Miners, businesses, and privacy-conscious users rely on particular behavior from the full nodes they use, so they will often run their own full nodes and take special safety precautions. This document does not cover those precautions—it only describes running a full node to help support the Bitcoin network in general.
Please consult an expert if you need help setting up your full node correctly to handle high-value and privacy-sensitive tasks.
Secure Your Wallet
It’s possible and safe to run a full node to support the network and use its wallet to store your bitcoins, but you must take the same precautions you would when using any Bitcoin wallet. Please see the securing your wallet page for more information.
Minimum Requirements
Bitcoin Core full nodes have certain requirements. If you try running a node on weak hardware, it may work—but you’ll likely spend more time dealing with issues. If you can meet the following requirements, you’ll have an easy-to-use node.
Note: many operating systems today (Windows, Mac, and Linux) enter a low-power mode after the screensaver activates, slowing or halting network traffic. This is often the default setting on laptops and on all Mac OS X laptops and desktops. Check your screensaver settings and disable automatic “sleep” or “suspend” options to ensure you support the network whenever your computer is running.
Possible Problems
Legal: Bitcoin use is prohibited or restricted in some areas.
Bandwidth limits: Some Internet plans will charge an additional amount for any excess upload bandwidth used that isn’t included in the plan. Worse, some providers may terminate your connection without warning because of overuse. We advise that you check whether your Internet connection is subjected to such limitations and monitor your bandwidth use so that you can stop Bitcoin Core before you reach your upload limit.
Anti-virus: Several people have placed parts of known computer viruses in the Bitcoin block chain. This block chain data can’t infect your computer, but some anti-virus programs quarantine the data anyway, making it more difficult to run a full node. This problem mostly affects computers running Windows.
Attack target: People who want to disrupt the Bitcoin network may attack full nodes in ways that will affect other things you do with your computer, such as an attack that limits your available download bandwidth or an attack that prevents you from using your full node’s wallet for sending transactions.
Linux Instructions
The following instructions describe installing Bitcoin Core on Linux systems.
Ubuntu 14.10 Instructions for Bitcoin Core 0.10.0.
If you use Ubuntu Desktop, click the Ubuntu swirl icon to start the Dash and type “term” into the input box. Choose any one of the terminals listed:
Alternatively, access a console or terminal emulator using another method, such as SSH on Ubuntu Server or a terminal launcher in an alternative desktop environment.
Type the following line to add the Bitcoin Personal Package Archive (PPA) to your system:
sudo apt-add-repository ppa:bitcoin/bitcoin
You will be prompted for your user password. Provide it to continue. Afterwards, the following text will be displayed:
Stable Channel of bitcoin-qt and bitcoind for Ubuntu, and their dependencies
More info: https://launchpad.net/~bitcoin/+archive/ubuntu/bitcoin
Press [ENTER] to continue or ctrl-c to cancel adding it
Press enter to continue. The following text (with some variations) will be displayed and you will be returned to the command line prompt:
gpg: keyring /tmp/tmpixuqu73x/secring.gpg' created gpg: keyring/tmp/tmpixuqu73x/pubring.gpg' created gpg: requesting key 8842CE5E from hkp server > > > >keyserver.ubuntu.com gpg: /tmp/tmpixuqu73x/trustdb.gpg: trustdb created gpg: key 8842CE5E: public key "Launchpad PPA for Bitcoin" imported gpg: no ultimately trusted keys found gpg: Total number processed: 1 pg: imported: 1 (RSA: 1) OK
Type the following line to get the most recent list of packages:
sudo apt-get update
A large number of lines will be displayed as different update files are downloaded. This step may take several minutes on a slow Internet connection.
To continue, choose one of the following options
sudo apt-get install bitcoin-qt
sudo apt-get install bitcoind
sudo apt-get install bitcoin-qt bitcoind
After choosing what packages to install, you will be asked whether you want to proceed. Press enter to continue.
If you’re logged in as an administrative user with sudo access, you may log out. The steps in this section should be performed as the user you want to run Bitcoin Core. (If you’re an expert administrator, you can make this a locked account used only by Bitcoin Core.)
Before using the Bitcoin Core daemon, bitcoind, you need to create its configuration file with a user name and password. First create the .bitcoin directory, create (touch) the file, and set the file’s permissions so that only your user account can read it. From the terminal, type:
mkdir ~/.bitcoin touch ~/.bitcoin/bitcoin.conf chmod 600 ~/.bitcoin/bitcoin.conf
Then you can run the command bitcoind. It will print output similar to this:
bitcoind Error: To use the "-server" option, you must set a rpcpassword in the configuration file: /home/bitcoinorg/.bitcoin/bitcoin.conf It is recommended you use the following random password: rpcuser=bitcoinrpc rpcpassword=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX (you do not need to remember this password)
The username and password MUST NOT be the same.
If the file does not exist, create it with owner-readable-only file permissions. It is also recommended to set alertnotify so you are notified of problems; for example: alertnotify=echo %s | mail -s "Bitcoin Alert" [email protected] The “rpcpassword” displayed will be unique for your system. You can copy the rpcuser and rpcpassword lines into your configuration file using the following commands. Note that in most Ubuntu terminals, you need to press Ctrl-Shift-C to copy and Ctrl-Shift-V to paste because Ctrl-C and Ctrl-V have different meanings in a Unix-style terminal.
echo rpcuser=bitcoinrpc >> ~/.bitcoin/bitcoin.conf echo rpcpassword=XXXXXX >> ~/.bitcoin/bitcoin.conf (Warning: Don’t use XXXXXX as your RPC password. Copy the rpcpassword displayed by bitcoind for your system.)
Now you can start Bitcoin Core daemon for real. Type the following command:
bitcoind -daemon
It will print a message that Bitcoin Core is starting. To interact with Bitcoin Core daemon, you will use the command bitcoin-cli (Bitcoin command line interface). Note: it may take up to several minutes for Bitcoin Core to start, during which it will display the following message whenever you use bitcoin-cli:
error: {"code":-28,"message":"Verifying blocks..."}
After it starts, you may find the following commands useful for basic interaction with your node:
to safely stop your node, run the following command:
bitcoin-cli stop
A complete list of commands is available in the Bitcoin.org developer reference.
When Bitcoin Core daemon first starts, it will begin to download the block chain. This step will take at least several hours, and it may take a day or more on a slow Internet connection or with a slow computer. During the download, Bitcoin Core will use a significant part of your connection bandwidth. You can stop Bitcoin Core at any time using the stop command; it will resume from the point where it stopped the next time you start it.
Optional: Start Your Node At Boot
Starting your node automatically each time your computer boots makes it easy for you to contribute to the network. The easiest way to do this is to start Bitcoin Core daemon from your crontab. To edit your crontab, run the following command:
crontab -e
@reboot bitcoind -daemon Save the file and exit; the updated crontab file will be installed for you. Now Bitcoin Core daemon will be automatically started each time your reboot your computer.
If you’re an Ubuntu expert and want to use an init script instead, see this Upstart script.
You have now completed installing Bitcoin Core. If you have any questions, please ask in one of Bitcoin’s many communities, such as Bitcoin StackExchange, BitcoinTalk technical support, or the #bitcoin IRC chatroom on Freenode.
To support the Bitcoin network, you also need to allow incoming connections. Please read the Network Configuration section for details.
Network Configuration
If you want to support the Bitcoin network, you must allow inbound connections.
When Bitcoin Core starts, it establishes 8 outbound connections to other full nodes so it can download the latest blocks and transactions. If you just want to use your full node as a wallet, you don’t need more than these 8 connections—but if you want to support lightweight clients and other full nodes on the network, you must allow inbound connections.
Servers connected directly to the Internet usually don’t require any special configuration. You can use the testing instructions below to confirm your server-based node accepts inbound connections.
Home connections are usually filtered by a router or modem. Bitcoin Core will request your router automatically configure itself to allow inbound connections to Bitcoin’s port, port 8333. Unfortunately many routers don’t allow automatic configuration, so you must manually configure your router. You may also need to configure your firewall to allow inbound connections to port 8333. Please see the following subsections for details.
Testing Connections
The BitNodes project provides an online tool to let you test whether your node accepts inbound connections. To use it, start Bitcoin Core (either the GUI or the daemon), wait 10 minutes, and then visit the GetAddr page (https://getaddr.bitnodes.io/). The tool will attempt to guess your IP address—if the address is wrong (or blank), you will need to enter your address manually.

Bitcoin Core full nodes have certain requirements. If you try running a node on weak hardware, it may work—but you’ll likely spend more time dealing with issues. If you can meet the following requirements, you’ll have an easy-to-use node.
Note: many operating systems today (Windows, Mac, and Linux) enter a low-power mode after the screensaver activates, slowing or halting network traffic. This is often the default setting on laptops and on all Mac OS X laptops and desktops. Check your screensaver settings and disable automatic “sleep” or “suspend” options to ensure you support the network whenever your computer is running.
Possible Problems
Legal: Bitcoin use is prohibited or restricted in some areas.
Bandwidth limits: Some Internet plans will charge an additional amount for any excess upload bandwidth used that isn’t included in the plan. Worse, some providers may terminate your connection without warning because of overuse. We advise that you check whether your Internet connection is subjected to such limitations and monitor your bandwidth use so that you can stop Bitcoin Core before you reach your upload limit.
Anti-virus: Several people have placed parts of known computer viruses in the Bitcoin block chain. This block chain data can’t infect your computer, but some anti-virus programs quarantine the data anyway, making it more difficult to run a full node. This problem mostly affects computers running Windows.
Attack target: People who want to disrupt the Bitcoin network may attack full nodes in ways that will affect other things you do with your computer, such as an attack that limits your available download bandwidth or an attack that prevents you from using your full node’s wallet for sending transactions.
Linux Instructions
The following instructions describe installing Bitcoin Core on Linux systems.
Ubuntu 14.10 Instructions for Bitcoin Core 0.10.0.
If you use Ubuntu Desktop, click the Ubuntu swirl icon to start the Dash and type “term” into the input box. Choose any one of the terminals listed:
Alternatively, access a console or terminal emulator using another method, such as SSH on Ubuntu Server or a terminal launcher in an alternative desktop environment.
Type the following line to add the Bitcoin Personal Package Archive (PPA) to your system:
sudo apt-add-repository ppa:bitcoin/bitcoin
You will be prompted for your user password. Provide it to continue. Afterwards, the following text will be displayed:
Stable Channel of bitcoin-qt and bitcoind for Ubuntu, and their dependencies
More info: https://launchpad.net/~bitcoin/+archive/ubuntu/bitcoin
Press [ENTER] to continue or ctrl-c to cancel adding it
Press enter to continue. The following text (with some variations) will be displayed and you will be returned to the command line prompt:
gpg: keyring /tmp/tmpixuqu73x/secring.gpg' created gpg: keyring/tmp/tmpixuqu73x/pubring.gpg' created gpg: requesting key 8842CE5E from hkp server > > > >keyserver.ubuntu.com gpg: /tmp/tmpixuqu73x/trustdb.gpg: trustdb created gpg: key 8842CE5E: public key "Launchpad PPA for Bitcoin" imported gpg: no ultimately trusted keys found gpg: Total number processed: 1 pg: imported: 1 (RSA: 1) OK
Type the following line to get the most recent list of packages:
sudo apt-get update
A large number of lines will be displayed as different update files are downloaded. This step may take several minutes on a slow Internet connection.
To continue, choose one of the following options
sudo apt-get install bitcoin-qt
sudo apt-get install bitcoind
sudo apt-get install bitcoin-qt bitcoind
After choosing what packages to install, you will be asked whether you want to proceed. Press enter to continue.
If you’re logged in as an administrative user with sudo access, you may log out. The steps in this section should be performed as the user you want to run Bitcoin Core. (If you’re an expert administrator, you can make this a locked account used only by Bitcoin Core.)
Before using the Bitcoin Core daemon, bitcoind, you need to create its configuration file with a user name and password. First create the .bitcoin directory, create (touch) the file, and set the file’s permissions so that only your user account can read it. From the terminal, type:
mkdir ~/.bitcoin touch ~/.bitcoin/bitcoin.conf chmod 600 ~/.bitcoin/bitcoin.conf
Then you can run the command bitcoind. It will print output similar to this:
bitcoind Error: To use the "-server" option, you must set a rpcpassword in the configuration file: /home/bitcoinorg/.bitcoin/bitcoin.conf It is recommended you use the following random password: rpcuser=bitcoinrpc rpcpassword=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX (you do not need to remember this password)
The username and password MUST NOT be the same.
If the file does not exist, create it with owner-readable-only file permissions. It is also recommended to set alertnotify so you are notified of problems; for example: alertnotify=echo %s | mail -s "Bitcoin Alert" [email protected] The “rpcpassword” displayed will be unique for your system. You can copy the rpcuser and rpcpassword lines into your configuration file using the following commands. Note that in most Ubuntu terminals, you need to press Ctrl-Shift-C to copy and Ctrl-Shift-V to paste because Ctrl-C and Ctrl-V have different meanings in a Unix-style terminal.
echo rpcuser=bitcoinrpc >> ~/.bitcoin/bitcoin.conf echo rpcpassword=XXXXXX >> ~/.bitcoin/bitcoin.conf (Warning: Don’t use XXXXXX as your RPC password. Copy the rpcpassword displayed by bitcoind for your system.)
Now you can start Bitcoin Core daemon for real. Type the following command:
bitcoind -daemon
It will print a message that Bitcoin Core is starting. To interact with Bitcoin Core daemon, you will use the command bitcoin-cli (Bitcoin command line interface). Note: it may take up to several minutes for Bitcoin Core to start, during which it will display the following message whenever you use bitcoin-cli:
error: {"code":-28,"message":"Verifying blocks..."}
After it starts, you may find the following commands useful for basic interaction with your node:
to safely stop your node, run the following command:
bitcoin-cli stop
A complete list of commands is available in the Bitcoin.org developer reference.
When Bitcoin Core daemon first starts, it will begin to download the block chain. This step will take at least several hours, and it may take a day or more on a slow Internet connection or with a slow computer. During the download, Bitcoin Core will use a significant part of your connection bandwidth. You can stop Bitcoin Core at any time using the stop command; it will resume from the point where it stopped the next time you start it.
Optional: Start Your Node At Boot
Starting your node automatically each time your computer boots makes it easy for you to contribute to the network. The easiest way to do this is to start Bitcoin Core daemon from your crontab. To edit your crontab, run the following command:
crontab -e
@reboot bitcoind -daemon Save the file and exit; the updated crontab file will be installed for you. Now Bitcoin Core daemon will be automatically started each time your reboot your computer.
If you’re an Ubuntu expert and want to use an init script instead, see this Upstart script.
You have now completed installing Bitcoin Core. If you have any questions, please ask in one of Bitcoin’s many communities, such as Bitcoin StackExchange, BitcoinTalk technical support, or the #bitcoin IRC chatroom on Freenode.
To support the Bitcoin network, you also need to allow incoming connections. Please read the Network Configuration section for details.
Network Configuration
If you want to support the Bitcoin network, you must allow inbound connections.
When Bitcoin Core starts, it establishes 8 outbound connections to other full nodes so it can download the latest blocks and transactions. If you just want to use your full node as a wallet, you don’t need more than these 8 connections—but if you want to support lightweight clients and other full nodes on the network, you must allow inbound connections.
Servers connected directly to the Internet usually don’t require any special configuration. You can use the testing instructions below to confirm your server-based node accepts inbound connections.
Home connections are usually filtered by a router or modem. Bitcoin Core will request your router automatically configure itself to allow inbound connections to Bitcoin’s port, port 8333. Unfortunately many routers don’t allow automatic configuration, so you must manually configure your router. You may also need to configure your firewall to allow inbound connections to port 8333. Please see the following subsections for details.
Testing Connections
The BitNodes project provides an online tool to let you test whether your node accepts inbound connections. To use it, start Bitcoin Core (either the GUI or the daemon), wait 10 minutes, and then visit the GetAddr page (https://getaddr.bitnodes.io/). The tool will attempt to guess your IP address—if the address is wrong (or blank), you will need to enter your address manually.

MARSCOIN MRS
Currently, there are two attempts underway to establish the first human base on Mars. While technologically not impossible funding such a project (estimated at 6-20 billion) is a major obstacle. If you share our dream of making that first giant step for mankind a reality, then Marscoin might be something for you.
Simply by using Marscoin, a bitcoin alternative, you will automatically participate in serious boostraping efforts to colonize Mars.
We donated 350,000 Marscoins to MarsOne, a non-profit that attempts to build the first colony on Mars. With your help - by adopting Marscoin - we will be able to help fund mankinds first colony on Mars simply by kickstarting the financial system of the future Mars colony!
In addition, once the colony is set up MarsOne or a Mars colonist could take Marscoin to Mars and install it. That means that your Marscoins would continue to be yours on Mars, forever.
