How do I download a bitcoin pruning node?

Does anyone have a link to how/where I can download a BTC pruning node? The links that I have seen (https://bitcoin.org/en/download for instance) all seem to download a full node first. I don't have the space needed for a full node but I'm planning to run some code on the incoming transactons.

Why run a Bitcoin Pruned Node?

Well, I want to run a Bitcoin Node, but I can't run it from my home or office.
There is any reason I should NOT run a Bitcoin Pruned Node if I can't run a Full node? Why I should run a Bitcoin Pruned Node? Is it helpful somehow?

Is there a way to prune the blockchain (like Bitcoin) so I can run a node on a RPi3?

I have a RPi3 that I'd like to run a node on, but the blockchain currently takes up about 9GB. Is there a way I can prune the blockchain (like Bitcoin's prune=) to save space?

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:

The bitcoin-qt core wallet in pruned mode, cold storage and scaling: test results.

CONCLUSION
 
DETAILS
First a wallet was created in the following way:
bitcoin-qt -connect=wrong_ip_address -prune=550 -listen=0 -datadir=/home/use.bitcoin_pruned &
The trick here is to add a wrong ip address so bitcoin-qt won't start loading blocks. The -listen=0 makes it possible to run bitcoin-qt while bitcoind (as a full archival node) is running in the background on the same computer.
 
Now some "watch only" addresses, that already had some bitcoin in them, were added
(in bitcoin-qt: help -> Debug window -> Console)
importaddress watch_only_address "" false
The pruned blockchain was then created by inserting the correct ip address (pointing to my node) or by removing "-connect=ip_address" completely.
 
Because bitcoin-qt was not the only program, creating the pruned blockchain was a very long process that took about 5 days! I could speed up the process a lot by turning off bitcoind and running the pruned node as a bitcoind with some extra priority:
sudo /usbin/ionice -c 2 -n 0 /usbin/nice -n -20 ./bitcoind -datadir=/home/use.bitcoin_pruned/
Had I done that from the start, it could have been much faster and maybe 1 or 2 days would have been enough.
The final pruned blockchain has a size of: 2542 MB so about 2.5 GB.
 
I now moved the wallet.dat to wallet.dat_back and restarted bitcoin-qt. The program will create a new wallet that can be used to receive and then send transactions. If you now add a private key that already has some bitcoins in it, they will NOT be visible. There is no reason for that as the balances (not the history) are in the UTXO set.
 
I now started bitcoin-qt with the original wallet.dat file. The bitcoins in the watch only addresses are now visible. I then imported the private key of one of the addresses but the move of the bitcoins from "Watch only" to "Spendable" was not visible in bitcoin-qt. However, after a restart of bitcoin-qt the funds were visible in the "Spendable" section of the wallet. I then did a transaction to another address. Now in this case I want the change of the transaction to stay within MY "watch only" addresses and they shouldn't move to the (arbitrary) addresses created when the wallet was created. This is fortunate possible in bitcoin-qt. You have to choose in bitcoin-qt:
Settings -> Options -> Wallet -> Enable coin controle features.
It is then possible to choose the return address to be one of the watch only addresses (with or without bitcoins in them). It all worked just fine! It is not clear to me why bitcoin-qt has the option to "importprunedfunds", that doesn't seem necessary.
 
Of course, a big thank you to all developers who implemented the currently available great features.

Which Bitcoin Scalability project deserves 5.75 BTC (~$46k)?

Back in 2012 I managed a bounty wallet dedicated to "Bitcoin Pruning", a scalability side-chain concept. The bounty collected 5.725 BTC and was meant to be donated to that specific project, but it never took off.
I'd like to make good use of these coins, and am looking for a suitable project or charity that deals specifically with improvements to Bitcoin's scalability. I am in touch with Anton from Scaling Bitcoin, and perhaps sponsoring that and giving the decision over to the conference's committee might be a good way to make proper use of the funds.
If you have any thoughts on established Bitcoin scalability projects that deserve & need funding please post them on this thread. Edit - I'm actually leaning towards letting the qualified committee of Scaling Bitcoin decide, instead of evaluating projects myself. Any reason you can think of not to delegate this to SB?
Edit: there has been a typo, the amount of money availble is 5.725 BTC and not 5.75 as the title states.

Lightning node on Windows - testing, get not connected

Ok after testing BTCPay, C-Lightning, LND on Ubuntu I said ok let's try also the Windows implementation, is just few clicks and done (as it is promoted).
So I followed this github guide that actually send you to this one.
OK, started Bitcoin-core client on Windows 7 x64, with an already synced data folder. Empty bitcoin.conf (none of guides says how to configure the conf file). Wait until the client is full synced. And then launched the windows-node-launcher (from a subfolder inside Bitcoin folder). All good, started slowly and a small popup appeared in systray saying Bitcoin node is syncing. Reviewed the config of Bitcoin and LND through that little app in systray and saw that bitcoin.conf was already filled with some settings. Didn't change anything. After 1 day (with the bitcoin blockchain already synced), the systray popup still says that is syncing and have a red dot. In the tutorial says that we have to leave it to sync until is blue and then green.
I said, ok maybe it has more things to do. So I open that LND Output link, to see what is going on... And I see that LND is not well.

bitcoin core pruning

i need to change the storage device my wallet is on. i noticed a new setting, pruning. if i set this to prune to 2gb the first time i open the wallet, will it prune automatically as i'm downloading the blockchain and always keep the size of the blockchain at 2gb, or do i need to download the entire 400gb block chain and then prune? i already have the full blockchain downloaded on my current storage device. is it possible to copy and paste that on to the new device without downloaded the whole thing again?
what does script verification threads do? makes me think of hyper threading. does this effect performance?

Technology improvements and their effects on the forces at play and the scalability of bitcoin.

This is a post about the potential technologies that can/are being done to bitcoin and their effects on how we can scale bitcoin.
Pruning
Pruning allows the stored blockchain size to be reduced significantly by not storing old data. This has the effect of lowering the resource requirements of running a node. a 40GB unpruned blockchain would be reduced in size to 550MB. (It is important to note that a pruned node has lower utility to the network)
.
Thin Blocks
Thin blocks uses the fact that most of the nodes in the network already have a list of almost all the same transactions ready to be put into the blockchain before a block is found. If all nodes use the same/similar policy for which transactions to include in a block then you only need to broadcast a small amount of information across the network for all nodes to know which transactions have been included (as opposed to broadcasting a list of all transactions included in the block). Thin Blocks have the advantage of reducing propagation which lowers the mining centralisation pressure due to orphaned blocks.
.
libsecp256k1 This allows a more efficient way of validating transactions. This means that propagation time is reduced which lowers the mining centralisation pressure due to orphaned blocks.
.
Serialised Broadcast
Currently block transmission to peers happens in parallel to all connected peers. Obviously for block propagation this is a poor choice in comparison to serial transmission to each peer one by one. Using parallel transmission means that the more peers you have, the slower the propagation, whereas serial transmission does not suffer this problem. The problem that serial transmission does suffer from though is variance. If the order that you send blocks to peers in is random, then it means sometimes you will send blocks to a peer who has a slow/fast connection and/or is able to validate slowly/quickly. This would mean the average propagation time would increase with serialised transmission but depending on your luck you would sometimes have faster propagation and sometimes have slower propagation. As this will lower propagation time it will also lower the mining centralisation pressure due to orphaned blocks. (This is just a concept at the moment but I don't see why it couldn't be implemented).
.
Know-Your-Neighbour (Serialised broadcast sorting)
This is a fix for the variance that would occur due to serialised broadcast. This sorts the order that you broadcast a block to each peer into; fastest upload + validation speed first and slowest upload speed and validation speed last. This not only decreases the variance to zero but also allows blocks to propagation to happen much faster. This also has the effect of lowering the mining centralisation pressure due to orphaned blocks. (This is just a concept at the moment but I don't see why it couldn't be implemented).
Here is a table below that shows roughly what the effects these solutions should have.
Name Bandwidth Broadcast Time Validation Time New Node Time Storage Space
Pruning 1 1 1 1 0.014
Thin Blocks 0.42 0.1 0.1 1 1
libsecp256k1 1 1 0.2 0.6 1
Serialised Broadcast 1 0.5 1 1 1
KYN 1 0.75 1 1 1
Segregated Witness 1 1 1 0.4 1
TOTAL 0.42 0.0375 0.02 0.24 0.014
Multiplier 2.38 26.7 50 - 70
The "multiplier" shows how many times higher the block size could be relative to the specific function. e.g. if all of these solution are applied, you could increase blocks to 10 times their current size without bandwidth increasing beyond current levels.
There seems to me to be four main fundamental forces at play; 'node distribution', 'mining decentralisation', 'network utility' and 'time'.
Node Distribution
Bandwidth has a relationship to node count and therefore 'node distribution'. This is because if bandwidth becomes too high then fewer people will be able to run a node. To a lesser extent bandwidth also effects 'mining decentralisation' as miners/pool owners also need to be able to run a node. I would argue that the centralisation pressures in relation to bandwidth are negligible though in comparison to the centralisation pressure caused by the usefulness of larger pools in reducing variance. The cost of a faster internet connection is negligible in comparison to the turnover of the pools. It is important to note the distinction between bandwidth required to propagate blocks quickly and the bandwidth required to propagate transactions. The bandwidth required to simply propagate transactions is still low today.
New node time (i.e. the time it takes to start up a new node) also has a relationship with node distribution. i.e. If it takes too long to start a new node then fewer people will be willing to take the time and resources to start a new node.
Storage Space also has a relationship with node distribution. If the blockchain takes up too much space on a computer then less people will be willing to store the whole blockchain.
Mining Decentralisation
Broadcast time (the time it takes to upload a block to a peer) has a relationship with mining centralisation pressures. This is because increasing broadcast time increases the propagation time, which increases the orphan rate. If the orphan rate it too high then individual miners will tend towards larger pools.
Validation time (the time it to validate a block) has a relationship with mining centralisation pressures. This is because increasing validation time increases the propagation time, which increases the orphan rate. If the orphan rate it too high then individual miners will tend towards larger pools.
Network Utility
Network Utility is one that I find is often overlooked, is not well understood but is equally as important. The network utility force acts as a kind of disclaimer to the other two forces. It has a balancing effect. Increasing the network utility will likely increase user adoption (The more useful something is, the more people will want to use it) and therefore decreasing network utility will likely decrease user adoption. User adoption has a relationship with node count. i.e. the more people, companies and organisations know about and use bitcoin, the more people, companies and organisations that will run nodes. For example we could reduce block size down to 10KB, which would reduce broadcast time and validation time significantly. This would also therefore reduce mining centralisation pressures significantly. What is very important to realise though is that network utility would also be significantly be reduced (fewer people able to use bitcoin) and therefore so would node distribution. Conversely, if we increased the block size (not the limit) right now to 1GB, the network utility would be very high as bitcoin would be able to process a large number of transactions but node distribution would be low and mining centralisation pressures would be high due to the larger resource requirements.
Time
Time is an important force because of how technology improves over time. Technology improves over time in a semi-predicable fashion. As we move through time, the cost of resources required to run the bitcoin network(if the resource requirements remained static) will decrease. This means that we are able to increase resource requirements proportional to technological improvements/cost reductions without any increase in costs to the network. Technological improvements are not perfectly predictable though so it could be advantageous to allow some buffer room for when technological improvements do not keep up with predictions. This buffer should not be applied at the expense of the balance between the other forces though (i.e. make the buffer too big and network utility will be significantly decreased).
We need to find a good balance between these four forces in bitcoin. I will soon make another post about a proposal that should keep all of these three forces balanced in a way that scales bitcoin on the blockchain and also still provides and incentives for off-chain, sidechain and second layer solutions. If we as a community can com together and find a solution to scale bitcoin, we have a real chance of changing the world.
(if anyone feels I have made any mistakes or am missing anything, please let me know. I don't have knowledge of exactly how much of a speed boost to bootstrapping a new node using Seg Wit creates. I'd appreciate if someone could help me out there.).
EDIT 1: Updated to a more accurate model of bandwidth when thin blocks are used.
Edit 2: A relevant detail.

Please correct my understanding of SegWit

In a hypothetical future where blocks only have segwit transactions:
1) Blocks will be composed of 1MB (non witness data) and 3MB (witness data)
2) We will have 1.7x the current transaction throughput capacity
3) Nodes can prune witness data after having validated it. This is the main selling point for segwit.
How does this compare to current bitcoin pruning? Would that need to be applied on top of this witness data pruning?

Please forgive the new account, but after getting some guidance on the #segwit-support slack channel, here are the steps for us Windows N00bs to keep the miners honest even if you don't have much space on your disk.

  1. Download and verify luke-jr core build here: http://luke.dashjr.org/programs/bitcoin/files/bitcoind/misc/0.14.x/core-0.14.2-uasfsegwit1.0/ Download the zip, not the exe.
  2. You can verify the checksum by installing 7-zip, and then using the context menu to make sure your download matches the sum found here: http://luke.dashjr.org/programs/bitcoin/files/bitcoind/misc/0.14.x/core-0.14.2-uasfsegwit1.0/SHA256SUMS
  3. Extract the zip contents to C:\Bitcoin Node
If you're like me and don't have space on your disk you can prune:
  1. Create a shortcut of bitcoin-qt.exe to your desktop.
  2. Right click on your shortcut and add this line to the "Target" field:
    "C:\Bitcoin Node\bitcoin-0.14.2\bin\bitcoin-qt.exe" -datadir=C:\Bitcoin -prune=550 -dbcache=3000 -listen=0
  3. Hit Apply.
  4. Run bitcoin qt using the shortcut. It will pass along the purning parameters, and you will be keeping the miner's honest come August 1.
Cheers!
