ChromaWallet (colored coins): issue and trade private currencies/stocks/bonds/..

[RawDog]

So... it's been a month and not much action here. Is this project still alive?

Dead.  Been dead for a long time actually.  Now it is mostly just KillerShitStorm's little hobby project.  We get a line or two of code every time he gets a day off.  But, it was never really a serious project anyway so no one is surprised.  Colored Coins has always been nothing more than an interesting curious concept.

ChromaWallet can be an excellent platform for our "Bitcoin Backed by Gold" project. I look forward to exploring potential synergies.

AlefBit doesn't believe it's dead.

seems no updated.

You can see the development progress here: https://github.com/bitcoinx/ngcccbase/commits/master

As you see, the last commit was 2 days ago. (But we also have commits which are yet to be merged, the last was 2 hours ago.)

I already explained that progress is much slower than I want it to be, but we keep working on it. (One of reasons for delay is civil unrest in the region I live in. (I live in Donestk.) It is hard to focus on code when we are on the brink of a civil war, and armed people on streets are a norm. Sorry.)

Our goal is to implement a thin SPV wallet (which gets data from servers, but verifies all the data it receives, so it doesn't need to trust that server), with p2ptrade and, potentially, other goodies.

It is very different from the web wallet CoinPrism have implemented: it is 100% dependent on server and lacks p2ptrade. (Which I'd say is the most complex component.)

Currently we have all main functions working, we are finishing SPV support and fixing smaller problems. p2ptrade is working as long as there is no abuse, we are going to add protection against abuse later.

I hopy you and your family are safe. Keep up the good work.

Does this have a different implementation from the original specification?

[killerstorm]

New build:

Linux 64-bit: http://killerstorm.xen.prgmr.com/alex/chromawallet-linux-x86_64-0.0.6.tbz
Windows 32-bit: http://killerstorm.xen.prgmr.com/alex/chromawallet-win32-0.0.6.zip

 * There is a history tab now.
 * It scans for received payments automatically in a background thread, there is no need to click 'Update', and it starts faster.
 * We use helloblock.io instead of blockchain.info because there were problems with blockchain.info. Also, helloblock.io works with testnet
 * Problem with invalid balances and things like that were solved. (Well, hopefully.) People who used older versions needs to run cw-cli full_rescan first
 * For now it simply trusts data it receives from helloblock.io. We already have 99% of SPV implementation, it will be present in the next version.
 * p2ptrade got several improvements, but might still be finnicky

Note: People who used older versions needs to run cw-cli full_rescan first.

Known issues: Old send and trade transactions will be displayed as 'unknown' in the history. We will address this later.

Some of problems which were reported by LOL were not fixed, particularly, it's possible to confuse it with 1-satoshi transaction, but it won't be in a permanently-stuck mode.

helloblock.io allows users to create and sign transactions?

so this implementation does not require the use of the bitcoind?

Why do you care about a SPV implementation of if you are using helloblock.io?  Can you explain?

[killerstorm]

helloblock.io allows users to create and sign transactions?

helloblock.io is used to get information about transactions. (E.g. scan for payments we received.) We also get information about transaction confirmations from them.

We create and sign transactions ourselves, via pycoin library.

so this implementation does not require the use of the bitcoind?

Yes, local bitcoind isn't required.

Why do you care about a SPV implementation of if you are using helloblock.io?  Can you explain?

SPV allows us to verify whether transaction was published in the blockchain. (Cryptographically.)

If helloblock.io gives us wrong information, it won't pass the check, and thus no damage will be done.

There is also an option to use Electrum servers. It isn't quite ready now, but in future it's going to be about as secure as Electrum.

ok, so i started to play around with it because i think this is awesome and i need it for a project.

Problem is that i can't run the software ngccc-gui.exe because i saved my testnet blockchain on another drive than the usual one (i chose a map on D instead of the usual C->appdata)
It gives an error when i run it: "IOerror: [errno2] no such file or directory < default path to blockchain> "

Is there a way to change the path?
My testnet bitcoinqt works as it should.

New version doesn't need local bitcoind/bitcoin-qt.

Thanks mate!

this last version: Testnet or real bitcoins already?

@lol: added you asset
Here is my adress for 'lol'
I browsed looked at the p2P market but can't see any offers so far, does it take a while to load?

I'm playing around with lol's coin

Code:

{"color_set": ["epobc:8243935d22411c86a3c6372367d84531821045a632a8728cf6b15fc3b24ce4f2:0:289962"], "monikers": ["lol"], "unit": 6000}

Posted an offer to buy one lol for 0.00001BTC (1000satoshi).
Can anyone see that one?

Try adding this instead:

Just to clarify, market is more-or-less real-time. You will only see offers if people who posted these offers are online.

Trade can be closed in about 10 seconds.

It is possible to cancel an offer before somebody fills it. It is cancelled immediately, but will still appear on others' orderbooks for about 30 seconds.

now i get an error that the moniker 'lol' already exists (because the previous one is still there) how do i remove a moniker? And can i rename the asset and use the same 'color' to connect to the same asset under a different name?

Edit: something else i'm curious about: does this client use the same 'protocol' to color the coins as the website coinprism? or are those two incompatible? I kinda like the broader definition options on coinprism, but i absolutely hate the fact that it uses a centralised webwallet. :p
