synchronization - Slow synchronisation bitcoin-qt - bread ...

much love to the Dogecoin community!

Just wanted to say that I love you guys! I'm new here, to the whole dogecoin thing, but from the beginning I can see that you guys are awesome!
The vibe around dogecoin is so fun and cheerful, and not overtly serious. It's great! We are just throwing DOGE everywhere to each other, to those who are helpful, to those who are funny, etc. I love this feeling of community here. I just love it. I feel that this feeling/vibe of the dogecoin will (and has already!) totally invite a ton of people to all of cryptocurrency.
I know for me personally, when I heard of dogecoin I said to myself that I wanted to try mining it. So I set out to learn, and using the doge mining guide (made by someone in the community!) I started to dig for dogecoins (a weasly ~10kH/s but that's alright haha).
And then on Reddit, someone tipped me 500 DOGE (Thank you shibeseller !). I felt so happy receiving that I wanted others to feel the same way so I decided to go tip others too! And through this cycle, I feel that we'll grow as a community!
So many thanks to all of you guys, for being awesome! I love this whole fun vibe and community of dogecoin. And never ever be overtly serious, you guys!
Thanks WiggleBooks
(PS whenever I open my Dogecoin wallet, it needs to synchronize (1000 blocks or so). It takes so long for this synchronization process, is there a way to make it sync faster?)

(Updated) [Staking] Reddcoin Core client GUI wallet on a Raspberry Pi Model 3B

Intro

This thread is an update to my first Reddcoin staking tutorial that was written 7 months ago.
 
The reason for the update
My Reddcoin Core software crashed and became unusable. My Raspberry Pi 3B would lag and freeze, I couldn't stake anymore.
 
Instead of just redoing everything the same way, I wanted to see if I could improve on 3 points:
 
The updates
 
If you would like to tip me
Writing a tutorial like this takes time and effort; tips are appreciated. My Reddcoin address: RqvdnNX5MTam855Y2Vudv7yVgtXdcYaQAW.

This video shows how long it takes to start Reddcoin Core.   TL;DR:
     

Extra

Backup
Backup your wallet to prevent losing the RDDs in your wallet! There are two methods to backup, do both. Make new backups if you create a new receiving address!
 
 
   
Boot with only 1 USB drive plugged in:
Make sure only the USB drive (with the swap partition and data partition) is plugged in when you boot up your Raspberry Pi. This to make sure the swap partition (/dev/sda1) is recognized correctly.   If you boot up with multiple USB drives, Lubuntu might see the USB drive with the swap partition as the second drive (instead of the first drive), and ignore the 2 GB swap partition. If this happens, starting Reddcoin can render the Raspberry Pi unresponsive.
   
Connection issues If you have issues syncing the blockchain because you have 0 network connections, please follow the instructions in this thread.
   
Start Reddcoin Core easier
Run a shell script (.sh file), so you can start Reddcoin just by double clicking on an icon on your Desktop.
   
Minimization options
Adjust minimization options, so you can safely press on the X button (the close/exit button on the upper right corner).
   
RealVNC VNC Viewer (client) and VNC Connect (server): To remote connect to the Raspberry Pi, I use VNC Viewer ad VNC Connect from RealVNC.
 
   
Chromium as browser: The updates break Firefox, the browser crashes when you try to run it. Install another browser, Chromium, to solve this issue.
   
Updates / Upgrades
If Software Updater shows up and tells you that there is updated software available, do not install the updates using Software Updater. Use LXTerminal to update Lubuntu.

Reddcoin Core 2.1

Reddcoin Core 2.1 will be an update to the core components of Reddcoin : reddcoin-qt and reddcoind. One of the key improvements is expected to be a speedup for the blockchain synchronization process - something we read a lot of negative comments about - and understandably so. I have a 2011 vintage laptop which I use for testing. It takes more than a few days to chew through the blockchain sync. Old though it may be, it’s my favorite benchmark of acceptable performance.
First let me explain why blockchain sync is slow, then explain what will be done to speed it up.
The Reddcoin blockchain is up to block 1760528 whereas Bitcoin is up to block 472265 (as I write this). That the Reddcoin blockchain is 3.7 times longer despite only having been alive since 21 Jan 2014 versus Bitcoin’s birth in 2009 may come as a surprise, until you remember that Reddcoin’s block time of 60s is one tenth’s of Bitcoin’s 10min block time. Under normal operating conditions on recent hardware you are unlikely to notice any performance hit. But the blockchain synchronization process cruelly throws the spotlight on one of the more CPU intensive aspects of maintaining a blockchain - block validation - something every network node does whether a new block is propagating through the network or an old block is being synced from either a bootstrap file or a network peer. Whatever performance issues Bitcoin 0.9 had during blockchain synchronization, Reddcoin necessarily suffers 10x worse.
Whilst making Bitcoin comparisons, it’s useful to recall the origins of our current Reddcoin Core 2.0.
Reddcoin Core 2.0 is based on Bitcoin 0.9 with the PoSV code from Reddcoin 1.4 reintegrated - work that @Gnasher completed almost a year ago specifically to incorporate the OP_RETURN feature from Bitcoin 0.9 which is a key enabler for Redd-ID. Peering at the Github tea leaves it is evident that synchronization performance was thought to be an issue in Bitcoin 0.9 because there were features introduced in later versions to address specifically this concern. And it is precisely these features we plan to integrate into Reddcoin Core 2.1 as part of the overall strategy of shadowing the Bitcoin code base as and when the need arises to move things forwards. My personal dream is getting SegWit live on Reddcoin, but clearly with rather empty blocks and 10x the capacity of Bitcoin, we’re way off needing something like a Reddcoin Lightening Network yet. But it is good to know we have that option open to us in our future road map.
Therefore the work currently underway for Reddcoin 2.1 is expected to include two features that will accelerate the blockchain synchronization process:
1 - “headers first” synchronization taken from Bitcoin 0.10
2 - Removal of the openssl lib dependency and replacing that very generic and slow elliptic curve crypto code with an optimized internal implementation originally developed for Bitcoin 0.12.
Whether this work will get Reddcoin Core all the way up to Bitcoin 0.12 remains to be seen. The base target is Bitcoin 0.10 with at least one 0.12 feature.
I don’t yet know what kind of speedup we should expect from this, but I am hopeful of something significant. I plan to publish timing comparisons once I have a beta of 2.1 with these features working. Anyone eager to know sooner is welcome to test Bitcoin 0.9 vs. Bitcoin 0.12.
Meanwhile with Redd-ID close to entering beta testing and a great mobile wallet team taking shape off the back of the recent upsurge of interest in Reddcoin, we can expect 2017 to be a good year for Reddcoin.
Keep on staking !

'''
Here's my situation.....
I know this is an all too common problem (and you've probably heard a lot of similar stories) but I'd appreciate any advice I can get. I purchased some bitcoins back in 2013. They were in a Bitcoin-QT wallet on my now very old and slow Macbook (which I still have). However, I wrote my passphrase on a piece of paper that is long gone now! I'm well aware that without the passphrase or seed phrase I'm unable to recover the coins.
HOWEVER, I might know part of the passphrase - but not too sure. I've now created a new BitcoinCore wallet and have imported the located the wallet.aes.json or wallet.dat file from the old mac (just waiting for the initial synchronization which should be finished in a couple of days.
I know it is difficult (if not impossible) to crack the passphrase via brute-force but I just heard about new Forensic software called Passphrase ([[link]2 ) that apparently has the ability to recover lost bitcoin passwords from Bitcoin.info and Bitcoin Core wallet services. It is very expensive (USD$1,095/year) but just wondering if anyone has used it before or knows how effective it will be in my situation.
Hoping someone can help!!!!!
Thanks

My first experience with bitcoin was NOT positive :( + Questions

After seeing an interesting comment on /funny in which bitcoin currency is used to make tips across reddit I started to investigate and learn about the Bitcoin. I had heard about it before but I didn't know how it worked or what I had to do in order to use it.
A dozen Bitcoin Wiki entries later I download bitcoin-qt and create my first wallet. The system seemed very easy and straightforward and I had already started to apply for "free starter bitcoins" when I met "synchronization".
Now synchronization is not necessarily a deal breaker but it was annoying as hell. I'm using an old computer and it seemed as if it would take at least a day if not more to complete the whole process... and during that time my computer was getting slow as hell.
Now I'm quite a tech savy person and I know why in this P2P based system this is important, but for anyone else this would be unacceptable. Imagine elder people or not so tech savy persons trying out the system for the first time and noticing that they can't use it without occupying 2+ GiB of their HardDrive and having to wait a lot.
I did not complete the sync and tried to use the multibit instead. But since I had already applied to the Free starter bitcoins on some websites I wanted to keep my old wallet. I try to look for an import/export button but it seems that Bitcoin-qt doesn't support exportation and I needed to use a third party application called pywallet (command line!) to export my wallet and convert it into another plaintext format since the format used by bitcoin-qt was not supported by multibit.
And one would assume that the first thing you do when creating such a currency is to define a standard for the wallet and the applications. Again, I know how to use the command line but anyone who doesn't and who just wants to try out the system for the first time would be inmediately turned off by this limitation.
These are all issues that need to be fixed and addressed. Also, at the current situation it is much more comfortable and easier to set up an e-wallet than using standalone software on my computer. And if you ask me, it beats the purpose of creating a decentralized currency when in the end the most popular e-wallet services are going to hold most bitcoins and suppose a great security risk.
So I ask you: do you know any solutions to the above mentioned problems? Is there any way to reduce the impact by those hindrances?
And now to the questions:
Since I'm a very inquisitive mind and I'm still very much interested in bitcoins I would like to ask some questions I couldn't find properly answered in the wiki about the nature of the bitcoin system and how exactly it works.
I'd be very grateful if you could answer any of the following questions:
1. What exactly is a bitcoin? A string of text? A hash? A file with a string of text?
2. If I'm not mistaken, a bitcoin wallet is made of a public key and a private key. If I want to transfer my wallet from one program to another or a piece of paper... would I need to export or print out the strings of text that form the bitcoins itself or do I just need those two keys?
3. How does the bitcoin system know how much balance is inside an wallet/account. Does it typically ONLY check it against the chainblock or does it also make use of any bitcoin strings stored inside the wallet?
4. Cryptographically speaking... what happens when I transfer bitcoins?
Thank you!
*Please don't downvote me just because my first experience was negative. I'm still very interested and would like to learn a lot more. *
Edit: Thank you very much for all your answers! I can't reply to all of you (mainly because it's very late over here) but I feel that I understand the concept much better and also feel much more comfortable knowing that the only thing I ever need is my private and public key. It makes me care much less about software and wallet.data files, knowing that I can have everything I need written on piece of paper or saved in an encrypted file of my own. Then, when I need to spend bitcoins or check my balance I can use whatever software I deem best at the moment.
Thank you!

Let me love the Bitcoin, please.

After reading tiny snippets about Bitcoin all the time I decided to take a closer look at it ... and I was floored.
Please don't get me wrong, I really really really want to love the concept, but it seems to be more or less unusable. There are some huge upsides to it: Built on mistrust, fixed amount of money, decentralized system, anonymity and so on. But my reality looked something like this:
Now as you might say, I should have read up on the details (blockchain!) before - but getting started seems to be a big hurdle for the non-geeks out there. Nothing like "get started in seconds!". Even I had some trouble grasping the concept, and I'm sitting in front of a computer for about two decades now.
But wait, there's more! Since my connection is still under heavy load from the client, I could read up on all the things I have missed, and I found some inherent flaws:
For me, Bitcoins could be an awesome form of worldwide, internet-based form of micropayments. The biggest market would be developing countries. But there are technical and legal barriers which push it into a corner for geeks who see conspiracies everywhere and want to crash the system ... which is exactly not what it should be. I read about Ripple, it seems to be a better alternative just because of the possibility for easy money exchanges - and it includes Bitcoin, too.
So, is there something I just don't get yet? I get the impression Bitcoin is a great idea, but just the prototype for something better.
