Do I need to enable wallet mode on my bitcoin full node running on a server?
I've began to run a bitcoin full node on a server recently. I'll use it for this purpose: when a customer at my e-shop chooses "payment in BTC" and sends bitcoins to a newly generated bitcoin address, I'll need to verify within 10-20 minutes, automatically, that a payment have arrived. Namely, that there's been at least 1 confirmation. And show an appropriate status to a user - "payment received successfully". I know how to interract with a full node via RCP interface. On a server I don't need to spend any bitcoins, only receive them and check confirmations. On my local computer - yes, I'll need to receive and spend bitcoins, and connect to my full node too, do other things. Do I need to enable "wallet mode" for the bitcoin full node on the server? disablewallet = 0 | 1 flag, that is.
Bitcoin Full Node: I repurposed some gaming computer parts and built a full node. (With Pics.)
I've been buying some Bitcoin lately and was interested in building a full node so I repurposed some old gaming computer parts that I had lying around. Here's the computer specifications and costs of new parts:
**Intel i5-6500k CPU-** A 4 core CPU that was a good gaming CPU back in its day. (Repurposed)
** Zalman CNPS9900MAX-B CPU Cooler - ** Cooler that was on the CPU/Motherboard when it was used for gaming. (Repurposed)
**MSI Z170A Gaming M5 Motherboard -** A good gaming and overclocking motherboard. (Repurposed)
**16GB G Skill 2400MHz RAM -** Great RAM for gaming and very fast at the time. (Repurposed)
**XFX 550w Power Supply (Gold) -** Rock solid power supply. (Repurposed.)
**Phanteks Eclipse 300A Computer Case -** Good quality case. $59.99 @ Amazon
**Sandisk SSD Plus 1TB Internal SSD -** Good quality SSD with room to grow with the Bitcoin network. $99.99 @ Amazon
**Windows 10 OS Key -** Couldn't find the original key that went with the motherboard. $34.99 @ Kinguin.net
Cost of new parts for this computer: $235.00 USD My observations: This computer is way overkill for a Bitcoin Full Node but works really great! I was unsure of what was really required for a computer to run a full node but after having this computer up and running for a few days I have a much better understanding. It hardly uses the CPU at all. I think that this is why you can run a full node on a Raspberry PI. The CPU on this computer typically runs at less than 5% utilization and more like 2%. It is basically sitting at idle all the time. I upped the data cache memory available in the Bitcoin GUI (Don't really know if this works or not?) to 5000 MB. The most RAM that I have used in several days of running has been less than 4 GB. (4000 MB) Once you get it up and running you need to open port 8333 on your router or it won't allow other computers to connect to you. Once you have port 8333 open, 20 computers will be able to connect to you and you will be able to connect to 10. There is very little documentation in how to do this (No step by step.) because all routers are slightly different and use slightly different terminology. It is not really that difficult. What you really want to do is called "port forwarding" and you want to find those settings in your router and port forward port 8333 in both directions. (Hope that made some sense. I'm not very good with networks!) My WiFi network and the connection to this computer is fast. I pay for 400 Mbps down and 20 Mbps up and I have a WiFi 6 router and a WiFi 6 adapter card in this computer. Speedtest says that this computer is connected at 380 Mbps down and 20 Mbps up. I'm about 40 feet away from the router. The Bitcoin Full Node is always transferring data on the network. It seems to be in small packets/batches but it is always sending or receiving or both. It doesn't use much bandwidth at one time so shouldn't cause lag on your network. In my case it typically stays under 500 Kbps but will on occasion spike briefly to 2000 Kbps (2 Mbps). I was very curious as to how much electricity this computer would use so that I could determine if I could afford to leave it on 24/7 or not. I plugged the computer into a watt meter that you can see in the pics. The computer swings between 32 and 35 watts while up and running on the Bitcoin network. This is like idle speed for this computer IMHO. 35 watts running 24 hours = 840 watt hours 840 watt hours X 30 days = 25200 watt hours or 25.2 Kwhs (Kilowatt hours is how you are charged by your utility) My utility charges $.12 per kilowatt hour so... 25.2 Kwh X $.12 = $3.03 USD per month. I hope I can afford that! Here's some pics: Bitcoin Full Node from Repurposed Parts
Hello, I'm looking to setup a Bitcoin full node, running in the background using a raspberry pi 4. Can I just Install 'bitcoin core GUI' using the raspiean buster desktop OS with a mouse, keyboard & LCD screen? Just like on a desktop computer then unplug the screen and mouse and leave it running? Surly that is the simplest way of doing it? Thanks
How to manually split Bitcoin Cash and Bitcoin SV with the standard bitcoin full node application and the other
I had a wallet.dat from the default bitcoin full node client which has been several addresses where the balances does'nt been changed since 2015. The last time I started the client was been beginning of 2017. So I want now to move all the created sub currencies to different addresses on they own currencies: Bitcoin, Bitcoin Cash, Bitcoin Gold, Bitcoin Private, Bitcoin Cash. Many full backups of the directory .bitcoin was been created for years. So first I started to created for each currency an own user. Each user got the newest own client software. I copied the .bitcoin directory to each user (.bitcoin must be changed to .bitcoingold) so each currency must not be download the full blockchain (only starting from 2017). After finished I transfered all the bitcoins to a new created addresses so no more bitcoins are on the old addresses. I made this through the network so the transaction is shown also in the blockchain. I did this also for bitcoingold without any problems. At bitcoin cash and sv it is more complex, because If I made a transaction in bitcoin cash also on bitcoin sv it could be possible the transaction was made. But it is possible to split it if you can create a transaction which is not valid in one of the chains where it is valid in the other. This is possible if you have allready a small value in one of the currencies. So I used a small amount in bitcoin cash: I transfered the bitcoin cash splitted amount to a new address on my full node wallet which holds the unsplitted values. I created on the local wallet a new address. I send all my amount including the splitted value to this new addess. In bitcoin cash the transaction was been valid so the new address now holds all the value where in bitcoin sv the value still was on the old adresses. Now in bitcoin sv full node client I created a new address and transfered all the value to this new address. In bitcoin sv the transaction was been now valid where in bitcoin cash the old addresses had been allready emtied and the transaction was denied by the network. Finished: my bitcoin cash and sv was been splitted. PS: It was hard to find information that this is possible. My first try to do this was been failed because I made a first transaction on bitcoin cash without a splitted value so the transaction was valid and execude on both chains. It was simply easy to save the moved amount also in bitcoin sv because I could extract the private address in bitcoin cash client and import them in bitcoin sv client so the value was been shown again. After this try I occured to me that it should be possible to split the amount by a value which is only availabe in one of the chains. This is the reason for this manual. Please be carefully to use the correct addresses for sending. Begin with a small amount (+ split amount) before sending the rest (+ split amount) :-) If you mean this was helpfull donation is welcome: bitcoin: 18H11zjyw6CX1kLvxA3UJEYNqpbHivqp5z bitcoin cash: qr4pg4pacvuh2dzau8rsdy9wpsrjth8mlyjj4ftray bitcoin sv: 1AdyKXpDiwVHuXeSkgCd314TPiuzt8EqjD bitcoin gold: GgWdEk1W3KJwCf8CMLi5fpLWSqukb64bNU bitcoin private: b1TR4rKsT6uV4md1GCP6S2Y7mxDFtAQJuus

When Ledger Live will talk with my Bitcoin full node?
I know that Electrum Wallet can be used with a Bitcoin full node for better privacy. But let be honest: the UI of Ledger Live is miles better than the UI of Electrum Wallet. I’ve listened in a podcast that Ledger was working on the possibility of Ledger Live to connect to to a Bitcoin full node for transaction broadcast and for wallet balance verification. @ledger, when can we expect that?

Running a full node is the only way you can use Bitcoin in a trustless way. You will know for sure that all the rules of Bitcoin are being followed, for example that no bitcoins are spent not belonging to the owner, that no coins were spent twice, that no inflation happens outside of the schedule and that all the rules needed to make the system ... A Bitcoin full node is software that allows businesses and advanced users to validate transactions and blocks on the blockchain of their choice. Running a full node is a read-only access to the blockchain. It does not give you power over the network, simply the ability to monitor it. For the majority of end-users, full nodes aren't required to run. Full nodes help enforce the consensus rules of the Bitcoin network. When a full node client is running, it downloads every new block and every new transaction and checks them to make sure they are valid. Here are some examples of consensus rules, though there are many more: Use this tool to check if your Bitcoin client is currently accepting incoming connections from other nodes. Port must be between 1024 and 65535. Start a Bitcoin full node on your Linux, Mac, BSD or Windows system to help validate and relay transactions across the Bitcoin network by running this command: What’s a Bitcoin full node? The Bitcoin network is a collection of computers all over the world running the Bitcoin Core software that verifies transactions and blocks. It’s the distribution of these “nodes” (the term for a computer attached to the network) and the fact that anyone can set one up that makes Bitcoin “decentralized.”
