Topic: Best independent client? (Read 3667 times)

Correct.  BitcoinJ is primarily focused on lightweight client mode, but BlueMatt has been working on adding the necessary verification code.  Not there yet, though.

Thanks for clarifying that.
As for BitcoinJ, I thought I read somewhere that it wasn't a full node at this time but might become one in the future. Can't find that post right now, though...

But if all bitcoind clients would go offline tomorrow, the other 2% would continue the network, right? (I understand how weak and vulnerable that network would be though)

In that case, I will be switching to an alternative client out of the few you mentioned somewhere next week. (Need some time to browse through the code and do some research). That 2% needs to be increased imho for the good of bitcoin.
Thank you for the answers Jeff, much appreciated.

pynode and ufasoft-coin are full, verifying nodes.  purecoin is too, I think, as is mtve's Perl bitcoin implementation.

The full nodes actually on the network are still 98% reference client (bitcoind).

I guess it depends what you mean by "depends on"

Their code doesn't depend on bitcoind in the classical sense, but as far as I know, they do still depend on
it because they are not full-verifying nodes, so a network without bitcoind nodes to connect to can't operate properly (correct me if I'm wrong).

 

This is incorrect.

BitcoinJ, pynode and ufasoft-coin do not depend at all on bitcoind.  Other alternate implementations also exist, in varying states of completion (bitcoin-alt, purecoin, ...)

cbitcoin (http://cbitcoin.com) is in alpha stage. This means it is probably has many issues. Feel free to experiment with it and contribute to it's development but I do not recommend using it for any applications yet.


cbitcoin isn't primarily focused on embedded systems. I only stated that the code could probably be adapted for embedded systems. It's designed with focus on portability and efficiency (Though I've not yet worked on optimisation yet) and it is currently a low-level library with many core bitcoin features. It doesn't contain everything you need for a fully validating client. Expect some announcements on cbitcoin in the upcoming weeks about the direction I plan to take it.


Anyone is very welcome to contribute code. The github repository is here: github.com/MatthewLM/cbitcoin and the documentation (incomplete and maybe inaccurate in areas) is here: http://cbitcoin.com/docs/index.html

I wouldn't quickly call myself ideal, but I'd probably be an option yes. There's limits of course on how much a person can do though. It would mean saying goodbye to at least one of my current projects, since I don't want take more time away from my family.
Since the other two projects currently serve a lot more people than bitcoin does, that'd be a difficult choice. Bitcoin has great potential though, so it's on my mind...


Number 1 would be very close to my field of work, so I could probably contribute some. I like the "fully verifying node" part of Nr. 2, and C++ is also manageable for me. As for nr3, with no disrespect meant to Mr. Corallo, I hate Java.

I've understood your point though. If it doesn't exist, contribute to it yourself. And I might, it's a good thought in any case.
However, there's many things in life that I think can be improved, created, started or changed. "Do it yourself" can never be the answer to all of them of course. In most cases, we'll have to rely on other people doing the work and can only hope to make our voice heard.

@The_Duke

From your posts you mention that you are:

1) a dev
2) clearly passionate about Bitcoin's future
3) already contributing to not-for-profit bodies

You are thus the ideal candidate to work on a bitcoin client/ server !

As far as I know that are 3 projects that are working in this area:

1) cbitcoin - written in C, primarily focused on embedded systems
2) libcoin - written in C++, designed to be a fully verifying node (eventually)
3) Matt Corallo has done a fair amount of work in extending bitcoinj to be fully verifying. (Java)

Take your pick.

To quote Terminator:

"There is no fate but what we make"

Wow, this is very well put. Thank you!

First of all, I doubt that it wouldn't happen for free. But for now, let's take your statement for truth.
I also agree with you that serious competition does not exist yet. I think most people will agree that it would be good (and in the spirit of bitcoin) to have multiple fully functioning clients to choose from.
If that is the case, then it should be one of TBF's missions to support this, perhaps even financially.
Instead, they support only ONE dev (or team), working on ONE client, which is exactly the ópposite of the above. They give this one client an even bigger lead over (possible) others. This dev that is going to get financial support is even on the board of TBF. Do you think it is likely that if another client stands up that is just as good as bitcoind or even better, that this board will decide to give less money to themselves and more to others? Even if that'd mean their own work might be overshadowed?


That is just FUD. You speak of me providing no evidence to say my arguments are moot, and then come up with this.


So it seems serious devotion and skill can come for free. That at least, has been proven so far. _{(I would even go as far as stating that you will find the most devotion, and possibly skill as well, in many of the non-corporate projects out there)}
Sidenote though: I highly doubt that if Gavin had not made a serious load of bitcoins in the progress he would have continued for so long. Just my opinion of course.


Not some. Tons.


Why not? Why not at least doubt their motives for this devotion? As long as what is good for bitcoin is also good for Gavin('s income), I am sure he will be really devoted. But I doubt that when the time comes that what is good for bitcoin is bad for Gavin('s income) he will still be so devoted to do the right thing for bitcoin. Perhaps I'm wrong, and if that time comes and Gavin proves me wrong I will be the first to applaud him for it.

Now, when Gavin is just one developer of many, maybe even supported by an organisation that also supports many others, that wouldn't worry me at all. Gavin would just be able to do his own thing and others would pick up where he left off, or take an alternative path.
But when Gavin is THE dev, making THE client, paid for by THE foundation (which is indirectly in the hands of THE big corporations in the market by then, mark my words), that becomes a scary thing.


Until now.


You missed all the other threads? Don't pretend it's just one guy not liking things, it's many.
 Insulting fashion? I have my doubts over the motives behind TBF and I voice them. If you think that is insulting, fine. I won't even say it's insulting that you think I am insulting!


I am a dev, both for a living (1) where I work on safety-critical products that millions of people use every day, and as part of two not-for-profit bodies (2). I get paid for (1), not for (2), even though (2) takes up more of my time than (1). I'm not a bloodlusting, selfish scammer, and if you pretend I said that Gavin was, then you're just putting words into my mouth that I did not say. But I'm also not going to all of a sudden demand that I get paid for (2). If I don't like the unpaid work anymore, I will go do something else. And doing so would not diminish my work I've done on those projects over the past 8 years.

But as soon as a dev starts asking for money for things he was always devoted to, it sets off alarm bells. It tells me (and I know you disagree, which is fine) that this dev has lost some of his devotion and/or the fun in what he was doing. And my advise to such a developer would not be to start asking for money, but to go do something else.


I seriously doubt that. I see brilliant programmers committing their work to NFP projects every day, in fields where their free software competes with others that are commercially exploited and their work is just as good.
But to come back to the original point: even IF what you say is true, then all the more reason for TBF to support multiple groups of devs, to actively strive to have competition, instead of trying to kill it off by picking one dev and one client.


At least you went from "will be" to "will probably be", but it's still FUD.


Yup, very happy about that!


Much less excited about that.  

There should be no dev's on the board. If there HAVE to be devs on the board, it should be at a later stage, and devs from multiple full clients. It could pay devs, but only if it was paying multiple devs in multiple groups developing multiple clients.
It should also not have people from MtGox, Bitinstant etc, nor should it be collecting funds from big corporations. They are your overlords, remember?


And what we have now, is a bunch of profit oriented people hiding behind the not-for-profit name. Seen MtGox's yearly reports yet? Plenty of profit there. Gavin himself is going to take money from this organisation, so that's profit for him right there. I don't think Bitinstant's CEO is doing it for free either.
I am not saying they are evil and will try to harm bitcoin from the start. I'm not even sayiong that working for profit is bad, I do so myself because having money makes life a lot easier. I'm saying that I am very unsure if they will do the right thing for bitcoin when a time comes where it will conflict with their own (financial) interests. They have too much investment into bitcoin. Into the *financial* aspects of bitcoin that is.


If I could provide that evidence, it would already be too late. I fear this evidence will come sooner or later. Not necessary from Gavin himself, but from the way TBF is set up.  


If you read my posts, you will see that the compensation part is just one of my issues with TBF and not even the major one. It is a large part of their mission statement and way TBF has been set up that I disagree with.


No, not something like TBF as we see it now. We can do without that.


I mildly agree with that.


But not with that. And not in the way these guys have set it up. But that much was clear I think

Now, how about we go back on topic? As a bitcoin user, I would like to have a client that is as independent as it can get from TBF, because I do not trust TBF (which you might disagree with, but that is off-topic).
Which projects should I follow and which clients can I forget about?

Well that's just what I've been picking up when the thread popped up. There was something about it being fully or at least sufficiently featured by now in the last update. I don't know any specifics.

I'm not arguing against having competition in the world of Bitcoin.  What I'm arguing is that it doesn't exist yet, and if it does, it's not going to happen for free.  And when it does, it will be with much worse intentions than this non-profit made up of people who actually care about Bitcoin.  

The complexity of the protocol and securing the fully-functioning network requires some serious devotion and skill.  The current devs have been doing this for years, for free.  Yes, maybe they made some money from BTC savings.  A lot of people did.  But no one [should] doubt their devotion to the success of Bitcoin, regardless of who they are working for or how much money they made.  These guys are serious nerds, and seriously devoted.   There's never been a reason to doubt that.  Except that you have, in an extraordinary and insulting fashion.  As if devs getting compensated for their time turns them into bloodlusting, selfish scammers.

Because of the complexity of the system, there's no way for competition to exist without salaries.  When it does, it will probably be supported by a profit-motivated "corporate overlord".  We should be happy that the first formal face to the outside world is a non-profit made up of these guys.  Because any other company trying to dive in like this will probably be profit-motivated, and made up mostly of people who don't actually care about Bitcoin.

The reason I was so straightforward in my previous message is because you've offered no evidence that the high degree of credibility developed by Gavin&friends over the years is in question.  Everyone on the Bitcoin Foundation has been contributing to Bitcoin in some way, for a long time.  They've promoted it, defended it, secured it, developed it, and tried to expand it.  But none of this matters to you.  You see that someone gets compensated for their time, and nothing good can follow.

All I can say is, in order for Bitcoin to succeed in the long run, something like the Bitcoin Foundation is necessary:  without it, "Silk Road" will remain the public face of Bitcoin, and it will never expand.  And if some organization is going to come about to try to organize, promote, and maintain the network, we should be damned happy it is these guys.

Is it? I've checked in there a few times and thought it was still very early and not far enough along. Is there any info on how it compares to bitcoind and whether it saves space or can do SPV?

Not sure how mature it is, but I believe Ufasoft Coin is an alternative full node client. Unfortunately, the gui is still quite basic, and it hasn't received much attention lately, but it might be worth checking out.

hint, hint, cbitcoin is ready to be used... it's a library not a client though.

I couldn't of said it better myself. I will restate that this is money we are dealing with. Not an operating system, not a game but actual money. We need to be very cautious, period, if we want this thing to outlive us.

You mean *you think* it is. Please do not misuse your position as a developer to tell other people what they should and should not believe.


That's great! Good job so far. The all for free part has to be seen in the light of the early-adopting-bitcoins that most of the core developers managed to acquire, and their rise in price so far though. I estimate that a large portion of the core-devs are sitting on somewhere between thousands of dollars to millions of dollars worth of coins. And with that, they have an interest in keeping the price of bitcoin high, which might potentially be a conflict of interest with what is actually best for bitcoin. I'm not saying that conflict is there at this moment. But just the fact that it might come up in the future should make you wonder if they are the right people to be on anything that is called THE bitcoin foundation...



To wildly assume that people disagreeing with any form of formal representation of bitcoin is destructive is... quite destructive. If you think I am spreading FUD, then please refrain from FUDding right back.


Which is bad and should be changed ASAP if you ask me. Why don't I see TBF fighting for thát?


Just you calling it "the main client" is one of these things that raised all sorts of red flags in my mind. There should not be a "main client" and TBF should actively strive to support MANY different clients, not one "main client" from one "main dev".


Who guarantees that? You? Gavin himself? TBF as a whole?


They might have been the ones *so far*. But don't you agree that it would be a lot better if mutliple groups would try to find and solve these problems? Doesn't that fit a whole lot better in bitcoins decentralized spirit? And doesn't TBF's attempt at supporting only one group or even only one dev stand in sharp contrast to that?


Which again is a very bad thing and should be changed ASAP. Bitcoin should not rely on one person or one team. And TBF is enhacing that reliance rather than trying to solve it.

So if possible (and that is what I am asking for in this thread), I would like to use a client that is as independent of TBF as possible.

Thanks etotheipi. You've worded it better than I ever could.

Even though many people are using bitcoin to transact large amounts of money, currently all (or at least most) of the work on the bitcoin core is done unpaid. This is simply unsustainable. As a developer, my altruism and general interest only goes so far. Any "independent" client will have the same problems.

Other blockchains such as litecoin will also have the same problem, eventually at least a few developers need to work on it full time to review code, build tests, verify etc... So all in all, I think the bitcoin foundation is good thing.

And don't forget that in the end it's the miners that have "control" over the network, they decide what gets into the block chain by choosing to run a certain version of the software. The developers can only "propose" changes. The "politicial structure" of bitcoin is not as straightforward as you make it seem The_Duke.

Your reaction to the Bitcoin foundation is extraordinary and FUD.  The team that works on the main Bitcoin client has not only proved themselves capable, but they have tirelessly fought to keep the network secure and moving forward, and all for free up until now.  To wildly assume that adding formal representation to Bitcoin and compensation for its contributors is the end of Bitcoin as we know it, is quite destructive. 

Whatever it is that you think is going to happen, keep in mind that Bitcoin-Qt/bitcoind is the Bitcoin network right now.  And it will be like that for a while.  I would be scared if these guys were unwilling to continue working on the main client (say, because they need income and were unappreciated).  Regardless of who they "work for", they will continue protecting the network and adapting it to future needs. 

To contrast this to others:  I mean no offense to electrum guys (or myself, working on Armory), but what they we are doing is re-implementing the Bitcoin protocol.  We write programs to interact with the network as it exists due to the Bitcoin-Qt/bitcoind.  But that's not the same as having to evolve this complex system in order to avoid security vulnerabilities and accommodate future growth (and the electrum guys contribute to that, too, but I don't think they could do it alone).  It's a lot easier to implement an existing solution than it is to solve it from scratch.  Gavin and the rest of them are the ones solving these problems.

tl;dr -- Whether you like Gavin and his new position or not, we rely on him and the rest of that team.  All other clients are dependent on the quality of Bitcoin-Qt and bitcoind.  The next major vulnerability that is discovered will be fixed by them.  It's possible to replace them, but not without paying large salaries and risking poorer quality -- and that is exactly what you seem to be complaining about.

EDIT: in the far future when Bitcoin gets bigger, this may change.  But it will change due to corporate influence much worse than this non-profit organization run by the guys that have poured their lives into seeing Bitcoin succeed.
