The bitcoin integration/testing source tree is at GitHub, and we (jgarzik/tcatm/gavinandresen right now) use GitHub's "pull request" feature to keep track of patches that people think are ready for integration into mainline bitcoin. This post is a walk-through of how to create a pull request.

1. You'll need a GitHub account; sign up for free, and set up git and ssh to work with GitHub.

2. You need a fork of the main bitcoin source tree. Login to your GitHub account, browse to the bitcoin project, then poke the little 'Fork' button near the top of the screen.

3. Connect that fork at GitHub with source code on your development machine. The easiest way to do that is to clone your github fork, using the SSH Read+Write URL github shows you on your fork's page. For example:

Code:

git clone git@github.com:your_github_name/bitcoin-git.git
cd bitcoin-git
git checkout -b niftynewfeature # Create a feature branch
... edit, test, re-edit, re-test...
git commit -a
git push git@github.com:your_github_name/bitcoin.git niftynewfeature:niftynewfeature

You might already have a clone of the bitcoin git tree that you've modified; you should push those changes into your new GitHub fork. Assuming you made your changes in the 'master' branch on your machine (next time you should create a specific feature branch), the command would be:

Code:

git commit -a
git rebase -i remotes/origin/HEAD # optional: lets you tidy up commits to create a clean patch
git push git@github.com:your_github_name/bitcoin.git master:niftynewfeature

4. Submit a PULL request by going to your fork's GitHub page, selecting the branch containing the changes you want pulled ("niftynewfeature" in the above example), and then poking the "Pull Request" button. Enter a good description of what your changes do and why they're a good idea and how everybody and their brother is already using them to make the world a better place .

Eventually, if all goes well, after discussion and argument and nit-picking and revision, your changes will get pulled into the bitcoin repository. If all doesn't go well, you (or the core developers) can close your pull request and resubmit it when the feature is perfect.

Is my guess right, and can any guru out here please help me?

Quote from: Mike Hearn on July 09, 2013, 03:20:37 PM

There have been quite a lot of threads lately with people complaining about the size of the block chain, specifically (1) how long it takes to download for new users and (2) the amount of disk space used, often combined with complaints that the "core dev team" isn't doing anything about it.

This is just a quick note to explain where we're up to with this.

Starting from a few days ago, MultiBit is the default recommended desktop client on the bitcoin.org choose your wallet page. MultiBit is a what we call an "SPV wallet" so is capable of processing thousands of blocks per second, and its checkpoints are refreshed frequently enough that for brand new users, they will usually be synced with the chain in 5 seconds or less. I'll explain a bit more about how this works in a moment, as we have many newbies join us in recent months who may not be familiar with the details.
At some point Bitcoin-Qt will change such that it's able to delete old blocks. The details are still being worked out, but most likely you'll be able to say "Use up to 10 GB of disk space" and it will never use more than that. Nodes will broadcast how much of the chain they have and are able to serve. New nodes that are starting from scratch will have to search out other nodes that still have the full chain and sync from them, but any node that just wasn't online for a while and needs to grab the latest parts of the chain will be able to use most of the others. By controlling disk space usage, you can also indirectly control bandwidth usage (you can't upload data you don't have).

The latter piece of work isn't done yet, basically because Pieter has been busy lately with other things (like: real life). He did the bulk of the work already last year, but some parts still need to be designed and written. Remember that nearly everyone taking part is still a volunteer except for Gavin.

Intro to SPV mode

OK, now that we're recommending MultiBit as the default wallet app for new users, what does this do? MultiBit is like the Android "Bitcoin Wallet" app by Andreas Schildbach. They're both based on the bitcoinj project that I run. Essentially, these clients download sub-parts of the block chain and then do a bunch of maths to verify that it all hangs together. Because it doesn't download the whole chain, an SPV wallet is light and fast. But because it does download and verify parts, an SPV wallet can talk to the regular P2P network because it doesn't really have to trust the remote server. This makes it more decentralised than something like Electrum or blockchain.info which relies on special servers.

How does this work? It's described in Satoshi's original white paper in the "simplified payment verification" section (hence, SPV). But here's a brief description to save you opening up your copy of his paper. Each block in the Bitcoin protocol has two parts, the header and a list of transactions. The header contains data linking the block to a place in the chain (like the hash of the previous block). A full Bitcoin node (Bitcoin-Qt/bitcoind) examines the block headers to figure out which chain of blocks has the most mining work done on it, and then verifies all the transactions in order in those blocks. The best chain determines the order the transactions are applied to the database and thus which transaction loses if there's a double spend. But (and this is crucial), the ordering is the only thing determined by miners. All the transactions still have to make sense. Miners don't have arbitrary power, if they mined a block that just magicked money out of nowhere or included bogus transactions, full nodes would all reject it.

In SPV mode things work differently. Because they don't download the full chain, they can't verify each transaction individually or build a copy of the database. Instead they verify the headers to find the best chain, and then assume the contents of the best chain must be correct. This is usually a valid assumption, because the majority of mining power is honest. However if there was to be a 51% attack then SPV wallets might display arbitrary nonsense for as long as the attack lasts. They would get back to reality once the good chain became longer (harder) than the bogus chain again.

This leads to the question of how SPV wallets find transactions that send them money, if they don't download the whole chain. The answer is they upload to the remote Bitcoin nodes a "filter", which that node applies to each transaction in the block. If the filter matches, the transaction is sent to the SPV wallet along with a mathematical proof that it was really in the chain (we call this proof a Merkle branch, after Ralph Merkle who invented them). The wallet verifies this proof and thus knows the transaction really was accepted by the majority of miners, without having to trust the server.

Because we're talking to random computers on the internet and not a trusted third party, the filter is designed to let you control your privacy. It is not a list of your addresses, as it is with the blockchain.info wallet. It's actually what we call a Bloom filter (named after Burton Howard Bloom who invented them in 1970). You can't directly get the users addresses back out of a Bloom filter, instead you have to test each one you find in the chain against it to see if it matches. Also, the filter can be made "noisy", which means it randomly matches some other addresses as well. When the Bitcoin P2P node you're downloading from finds a match, it doesn't know if it really found one of your transactions or if it was a false positive. And because there are so many P2P nodes, it's possible to split up your list of addresses and send a subset to lots of different peers, so none get an accurate idea of what's in your wallet (bitcoinj doesn't do that today though). By adjusting your false positive rate, you can decide how much bandwidth you want to spend on garbling the other nodes picture of your wallet. If you're on a very slow or expensive link you might decide you want no noise in your filter at all, if you're on a fast wifi connection, you might be OK with downloading a megabyte or two of other peoples transactions just to obscure which ones are yours.

Using these fancy mathematical tools MultiBit and the Android wallet app give us the same nice performance that we can get from a web wallet like blockchain.info or Coinbase, but without the need for any central servers and keeping Bitcoin's P2P nature intact. SPV wallets will always be fast no matter how popular Bitcoin gets. Together with being able to delete old blocks, these are our solutions to the ever-growing size of the chain - which has been Satoshi's plan since the very first day Bitcoin was announced.

I hope it's all clearer now and everyone understands what's going on.

Since i'm new to the scene, i would like to buy some very cheap, second hand, mining equipment to play with... I don't really NEED any equipment (i'm not desperate), so i'm not willing to pay more than what the equipment is actually worth (i would prefer to do a good deal, even if i have to wait a little longer).

I'm well aware that the chances of getting ROI are very slim, but i don't really care. I just want to try out ASIC mining if i find good equipment for a good price. This is also the reason why i'm not looking for expensive equipment (i'm not looking to setup a big miningfarm)

I found a new antminer U3 on ebay for 70 euro's, but the downside is that it's a big USB miner. I need a PC running at all times to continue mining, but i can't mine at work (because it looks like an asic miner, and since i'm working as a sysadmin, i guess my collegues would know i'm doing something that's not work related).

I'm actually looking for:
- a (very cheap) usb miner that looks like a USBstick (so i can plug it into my workPC, which is running 24/7, and benefit from the free electricity to)
or
- a (very cheap) miner with ethernet connection, so i can set it up at home, but i do not need to run a PC 24/7. The miner should be all-in (include PSU) and in full working condition

Does anybody have some old equipment laying around that is not being used anymore and he/she's willing to sell for cheap?

I would prefer to pay with paypal, since i'm new i don't really have a lot of BTC. If this is really an issue, i guess i can try to find a way to exchange my paypal fund to BTC.
I would also like to mention i don't need an escrow when i can pay with paypal, but i have no problems using one if the seller is requesting this. If i have to pay with BTC, we'll use an escrow without any discussion.

Last point: i'm living in western europe (think the netherlands), so i guess only people from europe will be interested, since shipping fees for non-EU countries would be to high to even make me an offer to sell old, cheap equipment...
