Hi, So I got a bitcoin core wallet about 2 years ago and completely forgot about. Well I started about 3 weeks ago now to download the blockchain and its on 41 weeks left. Its been on 41 weeks for 2 days. Can anyone give me some advice on to make it go faster? Its version 0.13.2 Thank you!
The download of Bitcoin Core from bitcoin.org/en/download fails the cryptographic signature check! It looks like the signing key expired many months ago (before the latest version was signed for download). We should always be paranoid when downloading bitcoin software, and the signature should never fail! EDIT: The key just needed refreshing
Bitcoin Core downloading 4 years worth of transactions. Any faster way??
I bought some coins back in 2012ish. Thought about selling in 2013-2014 but decided to wait it out. I'm ready to sell some of what I have but I have run into a major issue, my wallet is taking forever to sync. I'm running Bitcoin Core on an old Macbook (I don't use the laptop anymore, but haven't gotten rid of it or wiped it because of the bitcoin on it). When I opened Bitcoin Core over a week ago it said it had 4 years worth of transactions to download before I can make any transactions. It's been running over a week (plugged directly into the router, >100Mbps download speed) and currently the "Last received block was generated 1 year and 31 weeks ago." Is there any faster way to get my wallet updated? At this rate it may be another week or longer before it's caught up. I'm very inexperienced with BTC and only bought some on a whim years and years ago.
Hey all. I have been using bitcoin core forever. It has caused me many problems, but, it has got the job done. It's been fine ever since I set up my pc. I had bitcoin core downloaded on multiple externals. After moving, I had one external that I hadn't plugged in a very long time, and about a week ago, I did. Now, when I open the wallet, it says it is my first time and wants to know hwere to install the blocks. Based on the amount of HD space it said I had, I figured out that it was trying to load the index off my most recently plugged in space. It said I only had 130GB but needed 160. So, I figured if I just simply unplugged that newer HD and restarted, that when I did so the problem would be fixxed. So I did that, but when I opened the wallet again, it still said it was my first time. However, now it does show the correct HD that I wanted to load it on, but it now also says I can not use that location. If I have to g through the hell of getting the blocks again, I am honestly done for. Last time it took almost 3 months, because it would crash my pc and lose it's progress. I had to close it and reboot my pc every hour or so just to keep it from not saving its progress. So, what is going on here? I know my index is a few weeks out of date, but why is it now saying it is my first time and it wants to DL the blocks again? I can even see the folder on my original external that has all, or well, most of the blocks, saved in its parent folder. Should I just select a new location, let it boot, and then will it notice that the blocks are already their? I tried googling every chain of keywords relating to this that I could and could not find an answer, or even some one asking the same question. Down on my luck, really need a lucky break...thanks in advance...
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?
Can Bitcoin Core Receive Transactions without Finishing the Blockchain Download?
Hey, Sorry if this is a stupid question, but I'm downloading the entire blockchain atm, but it still has a few days left. I have some bitcoin sitting in an exchange and I would like to move it into my wallet. I noticed that I can generate a receiving address even while the blockchain is downloading, and I was wondering if any btc I send to this address will actually be deposited into my wallet. I tried with a small amount ~$5, and I don't see anything in my wallet atm, but I believe that's because I haven't downloaded the entire blockchain (including the small transaction I just did). Is this correct, and therefor would it be okay to transfer my btc from the exchange to the wallet while it's still downloading? Thanks for the help!

Is there a way of downloading the current state of the mempool or an example of it?
Hi everyone, I would like to test some algorithms to assemble a candidate block and also do some statistical analysis. In order to do this, I need an example of the mempool transactions. However, I wasn't able to find any simple way of downloading it. My best attempt so far was to download the data from the blockchain.info API accessing this link: https://blockchain.info/unconfirmed-transactions?format=json. However, I think the number of transactions is limited by 10 and usually the mempool has more than 10 thousand transactions. I also tried https://www.smartbit.com.au/txs/unconfirmed and https://blockchair.com/bitcoin/mempool/transactions, but they also limit the number of transactions and the access to the some important data, such as ancestor, is not so direct. The only solution I found so far was to install bitcoin core, download the entire chain (which I want to avoid) and only then be able to get the mempool transaction data. Anyway, I don't need to right now to get access to the mempool. I only need an example of a snapshot of it. Could anyone help me on this task? Thanks in advance
Hi, at work I may try to sell this idea to my boss, to setup a bitcoin lightning node. We have a good infrastructure and it would be quite cool to have a node running on one of our dedicated VMs. My boss or the person who will approve/deny this idea may ask me of course how much will this cost, in time and money. I didn't do much research yet, but seen several tutorials how to setup a lightning node... thus I may include also the time to do more research... Here various tutorials I've found so far: - Detailed guide to installing LND and Bitcoind on Ubuntu 16.04 LTS for Mainnet (this seems very good for ubuntu users) - Bitcoin Lightning Node on Ubuntu Linux - The Lightning Network: How to install and (hopefully) make money - Installing Lightning Network part 2: Here We Go Again - Bitcoin Lightning Network: run your node at home for fun and (no) profit (explains how to install LND, which saves space as the blockchain doesn't need to be stored locally) Other resources: - Bitcoin Core Download (since I use ubuntu I may use the PPA) - Lightning LND Releases (this still needs to be compiled) Can you help me estimating this task? I tried to split it into sub-tasks: - Install Ubuntu Linux on VM, setup SSH, firewalls, basic dependencies: 4h - Follow tutorial to install bitcoin and lightning daemons: 8h - Setup/automate backup: 4h - Documentation (write down notes -if different than existing tutorials- to make things work & share the results): 4h - Time spent researching, estimating, making an offelittle presentation of the project: 4h Total estimation: 3 days - The initial step to download and verify the blockchain (even if in prune mode it won't be stored, this is required) takes a few days Is this realistic? Did I forget some parts? Should I estimate more time? (I personally tend to underestimate tasks) Your feedback is welcome, thank you
Appreciate if anyone can give some advice. Ive been downloading for 4 days now. I have a Dell i5 processor with just a regular hard drive. Wish I had a SSD now. Its at 44% progress and Im getting impatient. I checked my task manager and my disk is at 100%. Im thinking that maybe the problem. CPU percentages seems pretty low and Memory fluctuates around 70% mostly.
