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

For example, you can create 1 billion shares, and make each share divisible into 1 million parts.

Genius, pure genius.  And how many parts are the million parts divisible by?

Well, basically one creates 10^15 atoms, 10^6 atoms represent 1 share. (That's simply a display convention, for convenience.)

OBC represents 1 atom with 1 satoshi. But ITOG does not.

Do you have a diploma in mathematics?

M. Sc. in applied math.

I know estimates are hard, but what's the new projection for when chroma wallet will be good enough? Next week? Another month?

[KeyserSozeMC]

This forum is so small.

Went through 10 pages to end up here and say: GOOD LUCK!

It started from Ethereum thread, it took me to another 6 websites until I got here. Had to read all the posts to get a deeper understanding.


All I can say: I'm excited!


Also,


BUMP!

Yeah, but it's from Phoenix University.  Dumbass.

As you see, I failed to complete it in January as promised. It happened not because the task is big, but because we made very little progress, sadly things didn't go well.

However, it looks like things are getting better now and we'll be able to make good progress. The deadline is two weeks (Feb 14), but I hope I'll get something sooner than that.

A lot depends on me personally at this stage, so if I'll get ill or something we'll get more delays

[plasm]

Take care of yourself.Especially when is close to success.

[cbeast]

I hope to see this soon. The waters are getting muddied by centralized scamcoins that claim to be Bitcoin protocol overlays yet require closed source api servers that reserve the right to restrict access. I'm not trying to rush you, just do it right and show these scammers that there are no shortcuts. Counterparty (that name was my idea for an escrow betting coin in 2012) is pretending to be decentralized. Mastercoin may work, but seems too fragile and will probably sacrifice decentraliztion to avoid double spending. Ethereum is nothing but a hodgepodge of ideas, vaporware, and hype.

 Colored Coins at least has your pledge to release open source chroma servers. Bitcoin deserves nothing less.

how did i overlook this thread ! ~ i'm working on a similar project myself! =) *awesome stuff here peepz!!!!

KILLASTORM -- STAY UP!!!!!

Can you give a status update?

[TKeenan]

...we made very little progress...

...sadly things didn't go well....

Can you give a status update?

Status update: Chroma Wallet died a long time ago.  Once Killerstorm spent more time bashing Mastercoin than developing Colored Coins, it was clear he knew he could not ever finish.  Now, the only whimper we hear are the last gasps of life. Status: Colored Coins are still dead.

[TKeenan]

Can you give a status update?

Please be advised that the Mastercoin OmniWallet is almost released and the new Distributed Exchange is coming on line March 15th.  That should excite you.  Plus, Mastercoin has about $4million in the bank remaining to continue the effort.  Should produce some interesting results in the coming year.

ChromaWallet 0.0.5 preview available:

Linux 64-bit: http://killerstorm.xen.prgmr.com/alex/chromawallet-linux-x86_64-0.0.5.tbz
Windows (32-bit): http://killerstorm.xen.prgmr.com/alex/chromawallet-win32-0.0.5.zip

New features:

• epobc coloring scheme solves many problem obc had
• works as thin wallet

In default configuration it doesn't rely on a local bitcoind, instead it gets data from blockchain.inf and/or chromanode service. (Electrum connector is in development.)

By default it works on mainnet, add --testnet parameter to run it in testnet mode. E.g. "chromawallet --testnet" or "cw-cli --testnet <command>".

If you want use old wallet, you can so so via "--wallet=<path-to-wallet>", e.g. "./chromawallet --wallet=wallet.db".

Note: It isn't safe enough for mainnet, don't use it with non-negligible amounts!

Congrats! Just did a git pull to play with it.

It's great to see this be made SPV; the idea that Colored Coins and similar things isn't SPV-compat without explicit miner support is a serious misconception.

[Peter Todd]

BTW if you want to add true SPV support rather than relying on bc.i/etc. to get the data, I need to add that code to python-bitcoinlib for other projects too.

[jtimon]

Yes, congratulations!

It's great to see this be made SPV; the idea that Colored Coins and similar things isn't SPV-compat without explicit miner support is a serious misconception.

Well, is not compatible with regular bitcoin SPV, but you can have colored SPV and you could even have a committed colored UTXO softfork as well (if there's a way for miners to clearly know about "colored coinbases", for which there's probably a coloring kernel).
So, yes, sorry because I've not explained this very clearly and I've probably spread some confusion about this.

Implementation consists of regular bitcoin SPV for UTXOs and backward-scan based coloring.

and you could even have a committed colored UTXO softfork as well (if there's a way for miners to clearly know about "colored coinbases", for which there's probably a coloring kernel).

CHECK_COLOR opcode is a simpler softfork solution.

CHECK_COLOR opcode is a simpler softfork solution.

Covenants are a more generic solution and I don't think OP_CHECK_COLOR will ever make it.
As you know my preference are tagged colors (hardfork).

Well, in terms of complexity, OP_CHECK_COLOR is something I could probably hack together over weekend... Simple solution are more likely to win. (See: worse is better.)

[killerstorm]

BTW if you want to add true SPV support rather than relying on bc.i/etc. to get the data, I need to add that code to python-bitcoinlib for other projects too.

Well, the plan was to use Electrum servers and borrow code from Electrum, but that code isn't directly usable, so I used a simpler option (trust what bc.i reports) for now.

Having this in library would, indeed, help...
