Re: [Bitcoin-development] Announcement: libcoin
Hi Michael, Let's talk a little bit more about this awesome stuff! 2012/3/22 Michael Grønager grona...@ceptacle.com 1- How close is Libcoin with original Bitcoin? I mean, the output is a little different, the bitcoind help output was disabled and, I'm afraid that Libcoin can possibly being distant from Bitcoin in the future... That can happen?! Well, I hope at some point to push libcoin to bitcoin, but that is not for me to decide ;) Well, +1000 for that!! Since bitcoin-qt and bitcoind binaries share a lot of functions... There is a need for some kind of library, right?! So, both (and even more apps) can use it! :) Anyway, I will strive at keeping the two synced - currently, they are almost in sync - even bip 16 is part of libcoin, but I have postponed generation of P2SH till after we were certain of 16 vs 17. So that is high on the list. I did a presentation of libcoin at BitCon12 in San Antonio - I will trow the slides at the web-side asap. AWESOME!! 2- Do you have plans to update Libcoin on every new upstream Bitcoin release? How fast will be this updates? Do you need more resources/people working on it? More people is always nice! I am using libcoin for my own bitcoin project, so that should guarantee that it will be kept up to date. I'll try to help you here... One thing that I like to try and announce is: Use P2Pool with libcoin instead Bitcoin! BUT, to that work, libcoin must behave EXACTLY like Bitcoin 0.6.0rc5 (at least). If it works, I'll update my P2Pool guide here: A Complete Guide to P2Pool - Merged Mining (BTC/NMC/DVC/IXC/I0C) plus LTC, Linux: https://bitcointalk.org/index.php?topic=62842.0 I think that this will bring much more eyes to Libcoin!! Don't you think?! Let's do it?!?! Another questions not involved directly with Libcoin/Bitcoin but, I'll need it for my future Bitcoin projects, and Libcoin is on my radar: 1- Do you know about Diaspora* Project? Yes, I even have an account :) COOL!! I just finish my Diaspora test environment, can you try it?! https://quilombas.com/ 2- Do you have skills in Ruby on Rails development? Nope... Too bad... lol My plan with Diaspora is to include a wallet for each user and, Libcoin sound perfect for it. If I use original bitcoind, each Diaspora user will consumes a lot of resources and I'll need to build a private cloud computing for running user's wallets more safely... You know when you log into Diaspora and there is a Cubbi.es app for it?! So, the same way Cubbi.es manages/shows your pictures within Diaspora, my (our) application will manage our Bitcoins!! And users will be able to send/sell Bitcoins between them (maybe integrating it with Bitcoin-OTC will be a good idea for the future)... /M Michael Gronager, PhD Director, Ceptacle Jens Juels Gade 33 2100 Copenhagen E Mobile: +45 31 45 14 01 E-mail: grona...@ceptacle.com Web: http://www.ceptacle.com/ Cheers!

Re: [Bitcoin-development] Announcement: libcoin
Michael,
Since libcoin is chain agnostic, I was wondering if the project can be
used like this:
When I install it with make install, I would like to have something like
this:
Regular file: /usr/local/bin/libcoincore # or whatever you like
Symlink - Regular file
/usr/local/bit/bitcoind - /usr/local/bin/libcoincore # bitcoind is a
symlink to libcoincore
/usr/local/bit/litecoind - /usr/local/bin/libcoincore # litecoind is a
symlink to libcoincore
/usr/local/bit/devcoind - /usr/local/bin/libcoincore # devcoind is a
symlink to libcoincore
/usr/local/bit/namecoind - /usr/local/bin/libcoincore # devcoind is a
symlink to libcoincore
...and so on...
So, libcoincore will interpret the ARGV[0] and, for each string, it will
initiate the appropriate internal functions...
I don't know if Libcoin already does something like that... I'm not a
developer/code reader... Just a small nerd with big ideas... ^_^
Thanks!

Hi again - and thanks for testing and finding this!
I have fixed the bug you reported:
The culprit was an implicit string constructor for the ChainAddress that
caused creation of a not fully initialized ChainAddress. The right way to
do it is using chain::getAddress(string) as the ChainAddress is chain
specific.
A git pull will fix it ;)
Cheers,
Michael

Hi Thiago,
Forgot to comment on the two latter:
$ bitcoind getaccountaddress
HTTP error code: 401
Error: couldn't parse reply from server
$ bitcoind listaccounts
HTTP error code: 401
Error: couldn't parse reply from server
401 = permission denied - you need to setup username / password either
on the commandline or in the bicoin.conf file to access those commands...
See in the bitcoind.cpp file for commands that you can use with and
without auth...
Those that contains an auth requires auth:
server.registerMethod(method_ptr(new GetBalance(wallet)), auth);
As opposed to:
server.registerMethod(method_ptr(new GetInfo(node)));
auth is defined by:
Auth auth(rpc_user, rpc_pass); // if rpc_user and rpc_pass are not
set, all authenticated methods becomes disallowed.
so you just experience the case explained in the comment ;) I admit
that the output could be more readable, though!

little different, the bitcoind help output was disabled and, I'm afraid
that Libcoin can possibly being distant from Bitcoin in the future... That

Hi Martin,
There are a couple of options of doing similarly...
In the libcoin repository you will find some code for btc and btcd, it is
some code I wrote a while ago and it needs to be updated. It functions as a
bitcoind master and slave. The btcd keeps the blockchain, but no wallet.
btc keeps the wallet and contact the btcd to get transaction info (like
send an address and get its transactions or send a transaction id and get
its details). It works (or worked when I wrote them) with the wallet.dat,
but needs a little update.
You could e.g. run one btcd on the machine and several btc instances to
get the functionality you asked for.
Further, btcd also enables a web wallet, where the private keys are stored
in your browsers local-store.
I will get the application updated, but most likely in a bit other setup
as it is something I intend to marketize in the near future.
Hope this answers your question.
Cheers,
Michael

Michael,
libcoin is AWESOME! Thanks!!!
Can I do the following scenario with libcoin ? :
1- Create a regular Linux user called blockchain, with home dir
pointed to /var/lib/libcoin/ (more or like Ubuntu/Debian mysql does);
2- Start bitcoind under user blockchain (the Bitcoin blockchain)
will be downloaded to /var/lib/libcoin/bitcoin/ directory);
3- As another regular user, called michael, I would like to run
bitcoind too but, I do not want to re-download the blockchain to its own
subdir, I want instead, to consult it (blockchain) through libcoin itself
(not by socket of JSON)...
So, the /home/michael/.bitcoin/ directory will have only wallet.dat and
related files, not the blockchain.
This is more or less what we can do with Bitcoin Electrum alternate
client but, with Electrum, it copy the whole blockchain to mysql... This is
terrible from my point of view, I think that there is no need to duplicate
the blockchain within MySQL in anyway.
I just imagine a bitcoin splited in two, blockchain in one side and
wallet in the other side.
This is possible with libcoin?!
Thank you again!

Re: [Bitcoin-development] Announcement: libcoin
I tried on another 11.10 machine with the normal boost 1.42 and things also worked as they should. However, I noticed a difference between your cmake output and mine: -- Found OpenSSL: /usr/lib/libssl.so;/usr/lib/libcrypto.so -- Found OpenSSL: /usr/lib/i386-linux-gnu/libssl.so;/usr/lib/i386-linux-gnu/libcrypto.so (found version 1..) Are you sure that the openssl libraries/includes found are the correct ones ? cmake finds your openssl libraries at /usr/lib/ which most likely will make it think that the includes are at /usr/include. I can see that at least X11 stuff is in /usr/lib/x386-linux-gnu like my openssl. Could there be an issue there ? SHA256 would normally be found in openssl/sha.h but if that is somehow corrupt ? Cheers, M PS: to get more debug output, please try a make VERBOSE=1 That will show what g++ flags that are used, and might help us. On 23/02/2012, at 18:31, Martinx - ジェームズ wrote: Hi Michael!

Re: [Bitcoin-development] Announcement: libcoin
You will also find the RPC server in libcoin blistering fast compared to the Satoshi client. (It was actually what got me to write libcoin in the first place...). The Satoshi client HTTP server executes all rpc commands in its own thread, but to do so, it needs to stop the thread of the Node, even though the command executed is just a query (i.e. not a SendTo), you hence have two threads blocking each other and when they wait, you wait... In libcoin all the query methods access the blockChain as a const object and they can hence safely query it without intervening the work of the Node thread. The exception are the SendTo methods that first query if a transaction can take place, then pushes it to the work-queue of the Node thread and again exits immediately. The actual execution then follows once the Node has finished its current tasks (e.g. validating a block). Hello Michael, I'm impressed by your refactorings, and hope some of them can make it into the Satoshi codebase. I am however not sure what you've said above is safe. In particular, how do you guarantee that no other thread modifies the blockchain structure while you are performing your query on it? Does the query code operate on a const copy of the structure, or is there guaranteed only one thread accessing it? I've been thinking about moving to read-write locks that allow multiple threads reading the datastructure simultaneously, but removing the locking all together sounds wrong to me. -- Pieter -- Try before you buy = See our experts in action!

Re: [Bitcoin-development] Announcement: libcoin
Hi Gregory, I played with the database sync as well to get further speedups, but in the latest version I could only get about 1% extra from this. In the Satoshi client there is a bunch of sleeps and mutexes (put in there with great generosity) for making threads run smoother and to avoid deadlock I guess. The big change in speed came from moving from the threading based setup to the async based setup, so I think these are the culprit. Further, as I also write somewhere in the wiki. I can measure that 50% of the time is consumed in verify, so there is not much left to optimize now. Actually, Berkeley DB does a quite decent job in caching reads so not even a cache should help.

Re: [Bitcoin-development] Announcement: libcoin
Would be fine for me, depends on the community, and it is one of those chunks that make many stall... The reason for building on bitcoin/bitcoin directly is that this created a history of all changes, and this way I had a working version running each day while doing the refactoring - with my wallet at stake! However, I think perhaps the bitcoin project should be split into a library, with a prototype client and the actual clients. This library facilitates this.

Re: [Bitcoin-development] Announcement: libcoin
Sounds great. Does it support merged mining? Also, I'm a bit skeptic about it being chain agnostic. I want to implement a chain with demurrage and I think I'll need to also change coinWallet and not only create an implementation of the interface Chain. Anyway, this will make the task much easier. Thank you. Until I have the time to code it, there's a little bounty (7.3 btc) for this in case you're interested. -- Keep Your Developer Skills Current with LearnDevNow!

Re: [Bitcoin-development] Announcement: libcoin
OK - from your path it looks like linux. What version of Boost do you use. I require 1.47 or 1.48. - I will change that, but it is quite handy for signal_sets - will make an alternative scheme though. And, as for 0.4 vs 0.5 - I have tried to follow the changes, which were mostly (?) related to the integration of the qt client, which would have to be re-done anyway. Then there were some deadlock fixes, that I don't need ;). A fix for a special attack, that I have included. But I will go over everything again.

Re: [Bitcoin-development] Announcement: libcoin
However, I think perhaps the bitcoin project should be split into a library, with a prototype client and the actual clients. This library facilitates this. I'll be trying your implementation soon. And libbitcoin/subvertx too. Partly because they're also non-interpreted, and partly to what seems better architected... To the minimal extent of my understanding... I'd like to see wallet ops completely separated from background chain ops. ie: have a chain daemon doing it's thing, updating, verifying, etc. The generator doing it's thing. And a wallet app that can independently manage separate wallets in parallel, referencing the live chain files as needed. It seems a library would allow quality focus on the separate functions and let apps/ui's use the fn's as desired on top. Right now, it seems I have to run bitcoind and can only deal with one wallet at a time, having to stop it, deal with state issues, swap in a new wallet, start it, and repeat till illness ensues :( And when the chain is being processed hard by the daemon cpuwise, bitcoin RPC takes minutes to respond, if ever or errors out. If wallet ops or statistical queries on the chain need it for integrity or reading, a db checkpoint/lock/logroll could be implemented into the chain demon processes with a client lib api to trigger it as needed. Don't know, just saying. fyi... boost 1.48 and db 4.8.30 work fine with 0.5.2, 0.5.x, and master, you just need to compile and include it by hand if you want it and your package manager doesn't have it. -- Keep Your Developer Skills Current with LearnDevNow!
