How to back up Blockchain for new Bitcoin Core install
I'll be reinstalling Windows 10 on a new system (motherboard) soon and need to move my Bitcoin Core client over as well. I don't want to redownload the whole blockchain. Is it as simple as just copying the "blocks" folder from the %AppData%/Roaming/Bitcoin directory and replacing after installing Core again?
Is it possible to make wallet.jmdat file without bitcoin core installed?
For my own security paranoia, I do not want my seed words typed into a computer that will connect to the internet. I want to generate my wallet.jmdat file on a fresh ubuntu install that is airgapped that I plan to overwrite as soon as I have transferred the file off this soon to be overwritten machine to use on my main ubuntu machine running joinmarket. Are there modifications I can make to the joinmarket.cfg file that will allow me to do that without downloading bitcoin core?
What would I need to install in Laravel to interact with Bitcoin-Core installed on the same linux server?
What would I need to install in Laravel to interact with Bitcoin-Core wallet installed on the same linux server? I want to be able to validate bitcoin payments for shopping cart products like overstock.com does.
Can someone please write an ELI5 "Quick Start" guide to using joinmarket assuming Win7 and Bitcoin Core installed, and usage is for anonymous sending only (not trying to be a market maker)
I consider myself an advanced computer user and a fairly smart guy but I don't know the inner workings of Bitcoin or the Bitcoin Core client and I just cannot follow the instructions here: https://github.com/chris-belchejoinmarket/wiki/Running-JoinMarket-with-Bitcoin-Core-full-node EDIT: I have successfully installed joinmarket. It's what happens after installation and how to send assuming a Bitcoin Core wallet that I don't understand. EDIT2: If anyone agrees there should be more clear instructions and can provide them, please do. Chris essentially doesn't see a problem and if everyone agrees with him then clearly I'm in the wrong place and I will just have to avail myself of the other mixing services that don't have as steep of a learning curve.
Armory requires me to have bitcoin core installed to run, but why not just use bitcoin core wallet? Do I need both?
I could never get Armory to run right anyway, but I'd like to have a local wallet instead of one relaying on a remote one like coinbase. Since I have bitcoin core-qt installed (it came with the bitcoind) as part of the infrastructure I needed to install Armory, should I bother trying to get Armory to run?
Thinking of installing bitcoin-core, but have a question. If i install the bitcoin-core software on my computer, and then it updates the blockchain, can I use that copy of blockchain with some other installation of bitcoin-core too?
Lets say tomorrow I have to reinstall my OS. Can I make a copy of the blockchain, and then reuse it with a new bitcoin-core installation, without having to download it again? My network is pretty costly for me, so I have to use the bandwidth judiciously, hence I need to know whether i can reuse what i download or not.
I Did It! I figured out how to use Bitcoin. I am downloading Bitcoin Core Wal. but have not used it yet. I have never used bitcoin. While it installs, I installed Electrum on my Mac & bought $4 of bit on CashApp & moved to My Wallet on Electrum. I lost like 11cents on $4.13. It there a cheaper way?
Hello everyone I know there's a lot of this posts out there, if you could send me to the best one or send me the best vid, blogue to follow the steps I would be appreciated. I want to buy bitcoins using euro currency. I have bitcoin core installed on my laptop. I was using coinbase but thinking to use binance or other if you could suggest. Also using (free) VPN atm - hotspot shield I'm getting a ledger nano S from their website What steps do I need? Also I have made one time purchase using Thor - I believe I transferred from coinbase to bitcoin core and than paid for it. I'm a noob but I would really like to buy BTC and store it for the long term. Also would you advise me to wait for a bigger drop? Thanks a lot
With Bitcoin Core installed and running on your computer: 1 - Is it possible to check the full list of blocks ever mined and their transactions, just like the info available at blockchain . com website? 2 - Are you automatically running a Full Node? 3 - Are you automatically doing hashes to try to mine the next block (even though nowadays it's impossible to do it with a regular pc)? 4 - Are you automatically verifying transactions broadcast by the nodes connected? 5 - If you are automatically verifying transactions, does it mean that you get small amounts of bitcoin for it, even when you don't mine the block?
Hey guys, does anyone have the checksums for the latest bitcoin core installer? Can't find it. I haven't done this in a while, and was trying to verify the installer with Kleopatra. Can someone post some pointers? Thanks for the help. I totally forgot how to do it.
I found an old wallet and recovery.txt file, but I'm clueless what to do.
Update: Seems to be an empty BitCoin wallet. Thanks to Im_Here_To_Fuck for the help. For those wondering: I took the wallet.dat and used PyWallet to get a wallet.txt file, which gave me a bunch of lines filled with ADDR, PUBKEY, RESERVE and SEC information. Based on that, it looks to be a Bitcoin wallet. I already have Bitcoin Core installed and Syncing, it's about 4 years behind as of this edit. No transactions showing right now with the wallet.dat replaced. I checked Bitcoin explorer for about 30 of the addresses listed - no transactions. Better to know its empty than wonder forever! The files are from 2013 and I don't have a clue if there is even a balance. I don't even remember what currency it was for or what the wallet belongs to. I ran PyWallet but it didn't really clarify anything for me - I think it may be LiteCoin but I'm still stuck - what now? How do I actually get into the wallet or better yet how do I figure out what wallet the recovery code is even for? Any help would be much appreciated. Thanks edit: I also noticed I found a debug.txt file and there are dates from 2009 / 2010 in there.
Hey everyone, I've been out of the crypto game for a long time, but managed to dig up a wallet that I had stored on an old PC from early 2015. It wouldn't have much in it, maybe a few BTC at most, but it would be nice to recover it and cash out. The machine had Bitcoin Core installed, hasn't been connected to the internet since 2015, and is currently interstate - I've copied wallet.dat and that's all I have access to for now. The wallet is encrypted, backed up, copied to multiple secure locations, etc, and I remember the passphrase, but from what I've read in other threads, the private keys are the important part and I may need to do a "key dump"? I tried installing Electrum and importing the wallet, but Electrum doesn't recognise the file. Am I right in thinking that the following would be the best solution?
Download and install Bitcoin Core.
Place wallet.dat into the appropriate directory.
Open Bitcoin Core and allow it to "catch up" and download 240 GB worth of blockchain history.
Possibly be forced to input the passphrase to access the wallet again, and transfer BTC out to an exchange of my choosing (unsure if this is how it would work at this stage).
Is there a way to recover the wallet without being forced to download hundreds of GB worth of data? I live in Australia, with typical Australia-tier internet, and it could quite literally take up to a week to download. Apologies if there's any shortfall of knowledge on my end of things, it's been a long time since I've kept up with crypto and things seem to have changed quite a bit over the last four years. I appreciate any advice, and y'all are welcome to shame me on my relative ignorance, lol. Thanks!
Could not connect to Bitcoin Core using JSON-RPC error message when launching Eclair
Hi! I am new to the Lightning Network and I am seeking to install a Lighting Network full node on my PC. I already have Bitcoin Core installed and my full bitcoin node working (version 0.17.1). I went through some steps to install the LN full node on a video on YouTube, following instructions from a Medium post: "How to run a Lightning Network node on Windows" (https://medium.com/coinmonks/guide-setup-a-lightning-network-node-on-windows-8475206807f). I installed Eclair (v0.2-beta9) from their Github page. But when I try to launch Eclair (with my Bitcoin Core node up and running), an error message pops us, saying:
Could not connect to Bitcoin Core using JSON-RPC. Make sure that Bitcoin Core is up and running and RPC parameters are correct.
Here is what I have in my Bitcoin Core .conf file: testnet=0 server=1 rpcuser=foo rpcpassword=bar txindex=1 zmqpubrawblock=tcp://127.0.0.1:29000 zmqpubrawtx=tcp://127.0.0.1:29000 addresstype=p2sh-segwit deprecatedrpc=signrawtransaction And in my eclair.conf file: eclair.chain=mainnet eclair.bitcoind.rpcport=8332 eclair.bitcoind.rpcuser=foo eclair.bitcoind.rpcpassword=bar eclair.node-alias=”myalias” eclair.node-color=ff9900 By the way, I went through an old thread on the same topic (https://www.reddit.com/lightningnetwork/comments/7rlk1e/could_not_connect_to_bitcoind_using_jsonrpc_any/), but the solutions proposed did not work for me. Your help would be greatly appreciated :-) Thanks!
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. 1. Install Bitcoin-Qt Since version 0.9, Bitcoin-Qt was renamed to Bitcoin Core t o reduce confusion between Bitcoin-the-network and Bitcoin-the-software. Bitcoin Core is a full Bitcoin client. It is a thick client, meaning it requires the full blockchain (explained below) on local disk to operate and expose blockchain back to the network to help relay and verify transactions. Thus, the Bitcoin Core project does not have the information necessary to help you verify the Bitcoin Core Snap packages. Additional verification with reproducible builds Experienced users who don't mind performing additional steps can take advantage of Bitcoin Core's reproducible builds and the signed checksums generated by contributors who Bitcoin Core is a community-driven free software project, released under the MIT license.
