[Bitcoin-development] Announcement: libcoin

[Bitcoin-development] Announcement: libcoin

[Michael Grønager]

Dear Bitcoiners,

libcoin is now in a state ready for its first release, which I would like to share with you!

=== libcoin is a crypto currency library based on the bitcoin/bitcoin "Satoshi" client. ===

Copenhagen, Denmark - 1st February 2012 Ceptacle announces the release of the first version of the crypto currency library "libcoin" based on the bitcoin/bitcoin "Satoshi" client.

libcoin also maintains a version of bitcoind that is a 100% compatible drop-in replacement of the bitcoin/bitcoind client: You can use it on the same computer on the same files and you can call it with the same scripts. And you can easily extend it without touching the basic bitcoin source files.

The libcoin/bitcoind client downloads the entire block chain 3.5 times faster than the bitcoin/bitcoind client. This is less than 90 minutes on a modern laptop!

In libcoin, the Satoshi client code has been completely refactored, properly encapsulating classes, removing all globals, moving from threads and mutexes to a pure asynchronous approach. Functionalities have been divided into logical units and libraries, minimizing dependencies for e.g. thin clients.

libcoin is chain agnostic, all chain (bitcoin, testnet, namecoin, litecoin, ...) specific settings are maintained from a single class (Chain) and hence experiments with chain settings, mining, security and digital currencies for research and educational purposes are easily accessible. See the ponzicoin example for how you define your own chain.

The build system of libcoin is based on CMake and supports builds of static and dynamic libraries on Linux, Mac OS X, and Windows.

The libcoin license is LGPL v. 3. This mean that you can use it in open source as well as in commercial projects, but improvements should go back into the libcoin library.

Very interesting. Do you know where this speedup came from?  It's not
typical for straight refactors that don't change datastructures and
the like to see such big speedups.

I see you have commented out code that disables fsync, which was my
first guess since I get big speedups from doing similar things.

Sounds very nice. Congratulations with the release!

Any plans for porting over bitcoin-qt?

Very interesting. Do you have any plans to push your refactored code into
Bitcoin upstream for future releases someday?

Looks interesting. However, it doesn't configure for me:
    http://paste.pocoo.org/show/544135/

I noticed it's forked from bitcoind 0.4.x. Do you plan to merge up to 0.5.x?

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.

Cheers,

M

Re: [Bitcoin-development] Announcement: libcoin

Well, it should be simple. libcoin separates all the stuff you would like to do from a gui from the actual code, so I think it could be done cleanly. I havn't looked much at qt though... But help would be appreciated ;)

Re: [Bitcoin-development] Announcement: libcoin

[Michael Grønager]

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.

Cheers,

M

Hi Luke,

Your CMake cannot find boost - use ccmake or cmake-gui to help it with the location. Btw what platform are you using ?

Re: [Bitcoin-development] Announcement: libcoin

[Jorge Timón]

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.

I didn't see anything useful in ccmake. Boost is in the standard locations 
(/usr/include/boost/ and /usr/lib/libboost*

Gentoo

Re: [Bitcoin-development] Announcement: libcoin

[Michael Grønager]

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.

Just wrote it in another mail, but I am quite certain it is the boost version - you need 1.48 (or 1.47).

Boost 1.46.1 is the latest stable on Gentoo.

Perhaps it would be easier to merge with the latest 0.4.x branch:

The error about not finding boost is a red herring and as far as I can
tell bogus. The problem is that it finds Qt and tries to configure
some Qt code that doesn't seem to have actually been released. Try
http://pastebin.ca/2108766

Also, you'll probably need to set BDB_INCLUDE_PATH manually or it
won't find db.h

Hope this helps,
Aidan

Upgrading to 1.47 did not change the error at all... :/

Re: [Bitcoin-development] Announcement: libcoin

[Michael Grønager]

In the CMakeLists.txt file in the libcoin root find the lines regarding Boost - it says 

... 1.48  ...

Change that to 1.47 and try again. I suggest you first remove your CMakeCache.txt though...

(the Qt stuff is most likely not the culprit)

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

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.

Re: [Bitcoin-development] Announcement: libcoin

[Michael Grønager]

I agree on your architectural considerations - and with libcoin you can have several wallets in the same application ( and several RPC servers for that matter). And ... they all use the same Node / blockchain.

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).

I have attached the code for a very simple one node, two wallet, libcoin client below (~30 lines), and I have added it to the libcoin source as an example (example name: extrawallets).

Once running, you can access your extra wallet using the RPC interface:
./extrawallet extragetbalance
And youy normal wallet by:
./extrawallet getbalance

I'll leave the generalization to an n-wallet gui application to the reader ;)

Cheers,

Michael

This should probably be

*    server.registerMethod(method_ptr(new ExtraGetBalance(extrawallet)));
*    server.registerMethod(method_ptr(new ExtraSendToAddress(extrawallet)), Auth("username","password"));

right?  Easy to miss if both wallets were empty in your quick test...  Awesome job with libcoin, BTW!

<gronager@ceptacle.com> > The libcoin/bitcoind client downloads the
entire block chain 3.5 times faster than the bitcoin/bitcoind client.
This is less than 90 minutes on a modern laptop!

I'm guessing that you benchmarked this against the version you forked
from rather than the current reference client?

If so— I suspect your speedup was almost entirely because you removed
the secure allocator and as a result fixed the mlock performance bug
[https://bitcointalk.org/index.php?topic=56491.0] as a side effect. On
some systems the mlock issue makes a very big difference (on other
systems not so much).

In any case, I finally got libbitcoin built and I'm disappointed to
report that in the same time it takes the reference client to fully
sync, libbitcoin only made it to height 138k (of course, because the
time is mostly spent late in the chain 138k is not very far along— I'm
guessing it's going to take libbitcoin 3x-4x longer all said)

I assume the reason it's actually slower is because it's CPU bound on
ECDSA checks, which are skipped in bitcoin in blocks up to the highest
hardcoded checkpoint.  Without that difference I suspect libbitcoin
would be about the same speed— maybe a little faster because of the
other changes you mentioned (though, e.g. lock profiling shows hardly
any contention during sync).

I don't doubt your rpc performance is a lot better. There is a
longstanding pull request for async rpc for the reference client that
hasn't been merged.

It ended up taking almost exactly twice as long, FWIW.

(and Gah: forgive the  autocompletion  of my fingers: I'm apparently
unable to type the word coin without prefacing it with bit)  *libcoin*

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.

Thanks:)

>  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?

The BlockChain class encapsulates all access to the blockchain and only give you access to certain restricted queries on the chain. Actually that was the case already in the satoshi client, I have only tried to formalize and encapsulate these queries in the code instead of having all the code poking around directly in the database and the blockfile.

I should note that the database still keeps a mutex to protect reads from writes.

I agree that constness alone does not guarantee thread safety, it is one of the things to use to get there. Great care should be taken not to read a value that is being changed at the same time, at least if that will render the result unusable.

The list of allowed queries are the const public methods of BlockChain. Some examples :
1.    bool isSpent(Coin coin) const;
2.    int getNumSpent(uint256 hash) const ;
3.    uint256 spentIn(Coin coin) const;

    /// Check if the hash of a block belongs to a block in the main chain:
4.    bool isInMainChain(const uint256 hash) const;
    
    /// Get the best height
5.    int getBestHeight() const { return _bestIndex->nHeight; }

Or e.g.:
6.    void getBlock(const uint256 hash, Block& block) const;

1-3. can be used to check if a COutPoint (now Coin) has been spent etc... This will only generate sane results, even if the two threads are both active on the same data structures.
Same goes for 4. and 6. copies a block from the block file to the Block& provided so no issues here either. 

I do, however, admit, that an extra review of all the public const methods would be wise, to ensure that I have not overlooked something. I'll open an issue on this and use a cold winter night on looking them over again.

Cheers,

Michael

Hi Michael!

 Thank you for libcoin! It is a awesome evolution for Bitcoin and for the
CryptoCurrencies as a hole... Thanks!!!

 Anyway, I am unable to compile libcoin under my Ubuntu 11.04. At this
machine, I have compiled and running Bitcoin (from sources), Namecoin,
Devcoin, Litecoin, IXcoin and I0coin, all from sources but, when I try to
compile libcoin, I got:

Hi Martinx,

I am looking into it now - I just tried on my Ubuntu 11.10 - I got by Script.cpp with no problems.

I have Boost 1.48.1, but I can't see that causing the issue - I will retry with a cleaner machine...

Re: [Bitcoin-development] Announcement: libcoin

[Michael Grønager]

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.

Re: [Bitcoin-development] Announcement: libcoin

[Michael Grønager]

Hi Martinx,

Another note:

boost 1.42 and openssl 1.0 has a conflict (you will see it when you try to compile coinHTTP with that specific combination: sslv2 has been removed from openssl, but boost still references it.)

You should do a :

sudo apt-get upgrade libboost-dev-all

to get the 1.46.1 library

/M

AWESOME!!!

I can compile libcoin at my Ubuntu 11.10... I just need to install:

sudo aptitude install libboost1.46-all-dev

...alongside with another already installed dependencies, and now it works!!

Thank you!
Thiago

Re: [Bitcoin-development] Announcement: libcoin

[Martinx - ジェームズ]

[-- Attachment #1: Type: text/plain, Size: 12303 bytes --]

Hi Michael!

 I just run "bitcoind", from libcoin ("sudo make install") sources, with
empty ~/.bitcoin directory and:

Terminal 1: bitcoind # apparently okay

Terminal 2:

$ bitcoind getinfo # okay
{
    "version" : 40001,
    "blocks" : 57733,
    "connections" : 8,
    "difficulty" : 11.84622815,
    "testnet" : false
}

# sleep a couple minutes

$ bitcoind getinfo # ok
{
    "version" : 40001,
    "blocks" : 67527,
    "connections" : 8,
    "difficulty" : 45.38582234,
    "testnet" : false
}


But...


$ bitcoind help
HTTP error code: 404
JSON RPC Error code: -36001
Method not found.

$ 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


 Any tips?! lol

Thanks!
Thiago

Re: [Bitcoin-development] Announcement: libcoin

[Michael Grønager]

Hi Thiago

I had in mind using the JSON RPC 2.0 system.description standard command instead of help, but I got sidetracked implementing it. Will look into it asap. Thanks for noting!

Re: [Bitcoin-development] Announcement: libcoin

[Michael Grønager]

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!

/M

Re: [Bitcoin-development] Announcement: libcoin

[Martinx - ジェームズ]

[-- Attachment #1: Type: text/plain, Size: 13393 bytes --]

Hi Michael,

 Thank you for your attention!

 Now, I'm trying to start libcoin's bitcoind using high ports but, it
always try to listen at 8332, no matter what I "say"...

 Look:

$ cat .bitcoin/bitcoin.conf
server=1
daemon=1
rpcuser=libcoin
rpcpassword=LibCoin13
rpcport=10332
port=10333

 But:

/usr/local/bin/bitcoind
Error: Address already in use

terminate called after throwing an instance of 'DbException'
  what():  DbEnv::close: Invalid argument
Aborted

 When I "strace it", I can see:

...
bind(12, {sa_family=AF_INET, sin_port=htons(8333),
sin_addr=inet_addr("0.0.0.0")}, 16) = -1 EADDRINUSE (Address already in use)
...

 I already tried:

/usr/local/bin/bitcoind --rpcport 10332
/usr/local/bin/bitcoind --rpcport=10332

 Without success...

Thanks again!
Thiago

Re: [Bitcoin-development] Announcement: libcoin

[Michael Grønager]

Just copied your bitcoin.conf file to my system and the server connects just fine to RPC on 10332
and I get using curl:

MacGronager:bin gronager$ curl --data-binary '{"jsonrpc": "2.0", "id":"curltest", "method": "getblockcount", "params": [] }' -H 'Content-Type: application/json' http://127.0.0.1:10332
{"jsonrpc":"2.0","result":168299,"error":null,"id":"curltest"}

Didn't do a retest on linux, but I am quite certain that it works there well as I had it running for weeks on port 9332 on amazon.

However, the "port" parameter will not work

> ...
> bind(12, {sa_family=AF_INET, sin_port=htons(8333), sin_addr=inet_addr("0.0.0.0")}, 16) = -1 EADDRINUSE (Address already in use)
> ...

and as you can see it connects to 8333 - that for the bitcoin protocol.

I havn't implemented "port" (have a look at the possible options in bitcoind.cpp). It was not on the official help list in bitcoind 0.4.0 (see init.cpp or do a bitcoin/bitcoind -help). But, I can implement it over the weekend if your need it.

I also tested the bitcoind --rpcport=10332 and it worked too using the commandline - both running as server and client.

/M

Re: [Bitcoin-development] Announcement: libcoin

[Michael Grønager]

OK - didn't took the weekend:

support for "port" is on github now :)

Only took two lines:

            ("port", value<unsigned short>(&port)->default_value(8333), "Listen on specified port for the p2p protocol")

and using the port option in the Node constructor (was there already):

        Node node(chain, data_dir, args.count("nolisten") ? "" : "0.0.0.0", lexical_cast<string>(port)); // it is also here we specify the use of a proxy!

/M

AWESOME!! Thank you!!

Anyway, I found a new problem... lol

/usr/local/bin/bitcoind getinfo #okay
{
    "version" : 40001,
    "blocks" : 168753,
    "connections" : 8,
    "difficulty" : 1376302.26788638,
    "testnet" : false
}

/usr/local/bin/bitcoind getaccountaddress ""  # okay...
1J4vNcvEdeCuLH4yvyoC2gxFEF4zquoJ87

/usr/local/bin/bitcoind listaccounts # NOT okay...
{
}

/usr/local/bin/bitcoind getaccountaddress "teste" # okay
1E6pGh6AAtuJdFXheZMp1zdYmvdqAQn9QT

/usr/local/bin/bitcoind listaccounts # NOT okay...
{
    "teste" : 0.00000000
}

Where is my default account listed at "listaccounts" output?!

Best,
Thiago

Re: [Bitcoin-development] Announcement: libcoin

[Michael Grønager]

I tried this and got:

./bitcoind listaccount:
{
}

bitcoind getnewaddress
1DumTDw6quNqnUegJsXL2AJjDA9fmxRY7o

./bitcoind setaccount 1DumTDw6quNqnUegJsXL2AJjDA9fmxRY7o test

./bitcoind listaccounts{
   "" : 0.00000000,
   "test" : 0.00000000
}

Seem like the default account ( "" ) need to be initialized ?? Will test the same with the old client and see if it behaves similarly..

/M

Re: [Bitcoin-development] Announcement: libcoin

[Michael Grønager]

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

Re: [Bitcoin-development] Announcement: libcoin

[Martinx - ジェームズ]

[-- Attachment #1: Type: text/plain, Size: 21191 bytes --]

Hi Michael,

 NOTE: Re-add bitcoin-dev to this thread on Cc...

 I'll test this ASAP! I REALLY need this feature (blockchain server <->
wallet client).

 I just want ask you some things...

 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?!

 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?


 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?

 2- Do you have skills in Ruby on Rails development?


Thank you!
Thiago

Re: [Bitcoin-development] Announcement: libcoin

[Martinx - ジェームズ]

[-- Attachment #1: Type: text/plain, Size: 18307 bytes --]

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!
Thiago

Re: [Bitcoin-development] Announcement: libcoin

[Michael Grønager]

> 
>  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 ;)

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.

> 
>  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.

>  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 :)

>  2- Do you have skills in Ruby on Rails development?

Nope...

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.

Re: [Bitcoin-development] Announcement: libcoin

[Peter Vessenes]

[-- Attachment #1: Type: text/plain, Size: 20813 bytes --]

This conversation reminds me that I'd like to see a comprehensive list of
tests that alt processors / generators can run against.

I haven't looked in the client code for some time, but does that exist now?
That would be a nice 'I want to help' early project, getting together
inputs and expected outputs / stack states for implementers to check
against.

As it is right now, we've split our codebase a bit; we rely on the client
to check the validity of a transaction, the balance of a given address, and
converse with the network, but we have written most of our own code for
stuff like block gen; I expect we will also do that for transaction
creation.

Hi!

 I'm trying to compile libcoin again and I'm seeing the following error:

libcoin@xapado:~/libcoin$ make

Hi Michael,

 Let's talk a little bit more about this awesome stuff!

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!  :)

 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?!?!

COOL!! I just finish my Diaspora test environment, can you try it?!

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)...

Guys!

 Only for the record, I'll integrate BitcoinJS (app) into Diaspora and, the
server side will be based on libcoin!
 Of course, this code will be part of Diaspora and every single Diaspora*
Pod will be able to host its own users's wallets...  ;-)
 I appreciate any help during this development!

Cheers!
Thiago

Hi Michael!

 I would like to ask you one thing:

 1- Release a new version of Libcoin closest as possible with mainline
Bitcoin.

 I mean, do not add any extra code to it and also, do not change any stdout
/ stderr messages.

 How much do you think that this will cost?

 For the extra code: I'll need to run the "blockchain side" as Linux user
called "blockchain" and, each of my regular Linux user will have its own
wallet.dat file (without the blockchain).

Thanks!
Thiago

Michael,

 I think it is time to your Libcoin to become the official Bitcoin...   ;-)

 Look: https://bitcointalk.org/index.php?topic=108987.msg1185827

 It is more or less the same idea, right?!

Best!
Thiago
