bitcoin-qt ready for use within half an hour … download an up-to-date pruned blockchain

Let us discuss how safe this is :-)
This tutorial is for Linux only but people using other operating systems will understand what to do.
Download the bitcoin blockchain
https://drive.google.com/drive/folders/0B0nH34wIYOSlSG81ZUZUZGZjVkE?usp=sharing
This will download (~20 minutes) the 2485 MB file:
bitcoin_blockchain_pruned_550MB_19aug2016.tar.gz
It contains only blocks, no wallet or log files. It has been created with -prune=550
Unpack
tar -zxvf bitcoin_blockchain_pruned_550MB_19aug2016.tar.gz
and observe it contains only blocks and chain state data. This will create the directory:
.bitcoin_pruned_550MB_19aug2016
Let’s assume you move this to ~/.bitcoin_pruned, so
mv .bitcoin_pruned_550MB_19aug2016 ~/.bitcoin_pruned
Run bitcoin-qt
When you start bitcoin-qt, a new wallet will be created: back it up first. My advice is to use bitcoin-qt 0.13.0rc3, because it creates a HD wallet that never runs out of addresses.
Start bitcoin-qt in fast start-up mode first:
bitcoin-qt –prune=550 –checklevel=2 –checkblocks=10 –checkblocksverify=10 –datadir=yourpath/.bitcoin_pruned
and let it sync quickly. Check more thoroughly next time with 10 -> 500000.
You can have a quick look at what’s happening:
tail ~/.bitcoin_pruned/debug.log.
 
FOR NOW, the drawback is that if you want to add addresses (watch-only or spendable) that already contain bitcoins, you have to create the pruned blockchain from scratch yourself, which takes a lot of time (or have someone with a full blockchain rescan the wallet for you). This is not really necessary: if the user is not interested in the history of his transactions, the balances can be obtained directly from the UTXO set. It has already been approved to add this feature in some future Core release:
https://github.com/bitcoin/bitcoin/issues?q=is%3Aissue+is%3Aopen+label%3AWallet, #8497.
I will automatically update the google drive with new up-to-date blockchains soon.
EDIT:
openssl dgst -sha256 bitcoin_blockchain_pruned_550MB_19aug2016.tar.gz SHA256(bitcoin_blockchain_pruned_550MB_19aug2016.tar.gz)= ce36bcb9ab691c358b27d3051f8f38452bc182ca636eae992563c60805a9d4b0

This is frustrating. This might be the 10th time I've had to try to explain this in this subreddit: Bitcoin-qt blockchain downloading is NOT network bound. It is HDD bound. Bitcoind/qt 0.8 greatly increases initial chain sync speed because it reduces the HDD bottleneck.

Swapped hard drives, now the bitcoin qt client is trying to download the blockchain to my solid state hard drive. Has anyone had this issue before?

I don't see options to look up what was already on my wallet that was on my other hard drive that I have connected. Instead it is just putting it on the new hard drive. Is there a way to have it save to the old hard drive?

Was using bitcoin-qt on OSX, blockchain got corrupted and now it is impossibly big to re-download, what thin clients can I import my wallet.dat into?? OSX 10.7.5. I already tried electrum and looks like I'd have to build it from github, can't figure it out. please help.

Send help! is there a safe way I could download a torrent of the blockchain? i tried to reindex the blockchain (after my harddrive got unplugged while bitcoin-qt was running) and it looks like it would literally take a week of spinning my poor laptop fan balls out.
edit: wallet.dat is encrypted and safely backed up.

How do I move private keys from Bitcoin-QT to another wallet without having the blockchain downloaded?

I currently access my bitcoins on Bitcoin-QT and have used a pretty good passphrase to encrypt the wallet.dat file. I would like to eventually move my coins to a paper wallet for offline storage, but currently want to get my coins over to blockchain.info (I set it up the account on a thumb-drive linux system with 2FA and a great password). I've read instances of people decrypting their wallet, then finding some unknown malware on their computer immediately emptying their wallets. I don't want to rely on the computer I currently have my wallet.dat file on just in case this happens to me. I'm trying to get my private keys into something like electrum or multibit using pywallet to decrypt my wallet.dat on a fresh linux system (thumb-drive again). However, the format from pywallet doesn't seem to be right to get it on electrum nor multibit.
Is there a special way to extract the private keys from wallet.dat to import them into multibit or electrum? I don't think using Bitcoin-QT on my thumb drive is an option since the blockchain is so huge and I think the blockchain is needed to do anything with Bitcoin-QT.
I didn't find too much help via google or the security guide on the right side of this page.

What is advantageous in downloading whole blockchain on the hard drive as in Bitcoin QT, and why does clients like Electrum get away without it?

It seems cumbersome downloading few gigs of data just to make several transactions, but I recon it has its reasons. Isn't its potentially harmful to the network if more people used Electrum? It seems kind of like leeching in the Torrent network.

Bitcoin qt not downloading blockchain

Hi /Bitcoin
I have a problem with my bitcoin qt client, I have used my wallet on the client to send and receive bitcoins several times, but recently it has just stopped downloading the blockchain, it is stuck on 282 weeks, since I have bitcoins on the wallet I'm not really happy to lose it.
Here is a list of what I have tried
  1. Downloading the blockchain (bootstrap.dat) from a torrent and moving it to C:\Users\"USER"\AppData\Roaming\Bitcoin, but this just renames the file to bootstrap.dat.old after a while.
  2. Downloading the new bitcoin qt version(v0.9.1.0)
  3. Letting it download for several hours
Nothing works and it just keeps saying "Synchronizing with network" and "282 weeks behind"

Does Armory and Bitcoin-QT download seperate (but the same) blockchain, or do they both work off of the same blockchain (so you only need to download it once with either of them, and then you can use both)?

I want to know if I can "uninstall" bitcoin-qt and the blockchain it downloaded if it is using a "different" one than Armory since I'm using Armory now.

Gridcoin 5.0.0.0-Mandatory "Fern" Release

https://github.com/gridcoin-community/Gridcoin-Research/releases/tag/5.0.0.0
Finally! After over ten months of development and testing, "Fern" has arrived! This is a whopper. 240 pull requests merged. Essentially a complete rewrite that was started with the scraper (the "neural net" rewrite) in "Denise" has now been completed. Practically the ENTIRE Gridcoin specific codebase resting on top of the vanilla Bitcoin/Peercoin/Blackcoin vanilla PoS code has been rewritten. This removes the team requirement at last (see below), although there are many other important improvements besides that.
Fern was a monumental undertaking. We had to encode all of the old rules active for the v10 block protocol in new code and ensure that the new code was 100% compatible. This had to be done in such a way as to clear out all of the old spaghetti and ring-fence it with tightly controlled class implementations. We then wrote an entirely new, simplified ruleset for research rewards and reengineered contracts (which includes beacon management, polls, and voting) using properly classed code. The fundamentals of Gridcoin with this release are now on a very sound and maintainable footing, and the developers believe the codebase as updated here will serve as the fundamental basis for Gridcoin's future roadmap.
We have been testing this for MONTHS on testnet in various stages. The v10 (legacy) compatibility code has been running on testnet continuously as it was developed to ensure compatibility with existing nodes. During the last few months, we have done two private testnet forks and then the full public testnet testing for v11 code (the new protocol which is what Fern implements). The developers have also been running non-staking "sentinel" nodes on mainnet with this code to verify that the consensus rules are problem-free for the legacy compatibility code on the broader mainnet. We believe this amount of testing is going to result in a smooth rollout.
Given the amount of changes in Fern, I am presenting TWO changelogs below. One is high level, which summarizes the most significant changes in the protocol. The second changelog is the detailed one in the usual format, and gives you an inkling of the size of this release.

Highlights

Protocol

Note that the protocol changes will not become active until we cross the hard-fork transition height to v11, which has been set at 2053000. Given current average block spacing, this should happen around October 4, about one month from now.
Note that to get all of the beacons in the network on the new protocol, we are requiring ALL beacons to be validated. A two week (14 day) grace period is provided by the code, starting at the time of the transition height, for people currently holding a beacon to validate the beacon and prevent it from expiring. That means that EVERY CRUNCHER must advertise and validate their beacon AFTER the v11 transition (around Oct 4th) and BEFORE October 18th (or more precisely, 14 days from the actual date of the v11 transition). If you do not advertise and validate your beacon by this time, your beacon will expire and you will stop earning research rewards until you advertise and validate a new beacon. This process has been made much easier by a brand new beacon "wizard" that helps manage beacon advertisements and renewals. Once a beacon has been validated and is a v11 protocol beacon, the normal 180 day expiration rules apply. Note, however, that the 180 day expiration on research rewards has been removed with the Fern update. This means that while your beacon might expire after 180 days, your earned research rewards will be retained and can be claimed by advertising a beacon with the same CPID and going through the validation process again. In other words, you do not lose any earned research rewards if you do not stake a block within 180 days and keep your beacon up-to-date.
The transition height is also when the team requirement will be relaxed for the network.

GUI

Besides the beacon wizard, there are a number of improvements to the GUI, including new UI transaction types (and icons) for staking the superblock, sidestake sends, beacon advertisement, voting, poll creation, and transactions with a message. The main screen has been revamped with a better summary section, and better status icons. Several changes under the hood have improved GUI performance. And finally, the diagnostics have been revamped.

Blockchain

The wallet sync speed has been DRASTICALLY improved. A decent machine with a good network connection should be able to sync the entire mainnet blockchain in less than 4 hours. A fast machine with a really fast network connection and a good SSD can do it in about 2.5 hours. One of our goals was to reduce or eliminate the reliance on snapshots for mainnet, and I think we have accomplished that goal with the new sync speed. We have also streamlined the in-memory structures for the blockchain which shaves some memory use.
There are so many goodies here it is hard to summarize them all.
I would like to thank all of the contributors to this release, but especially thank @cyrossignol, whose incredible contributions formed the backbone of this release. I would also like to pay special thanks to @barton2526, @caraka, and @Quezacoatl1, who tirelessly helped during the testing and polishing phase on testnet with testing and repeated builds for all architectures.
The developers are proud to present this release to the community and we believe this represents the starting point for a true renaissance for Gridcoin!

Summary Changelog

Accrual

Changed

Most significantly, nodes calculate research rewards directly from the magnitudes in EACH superblock between stakes instead of using a two- or three- point average based on a CPID's current magnitude and the magnitude for the CPID when it last staked. For those long-timers in the community, this has been referred to as "Superblock Windows," and was first done in proof-of-concept form by @denravonska.
