How is the website coming along?

Would it be possible to get say monthly updates on development of B&C?

Would it be possible to get say monthly updates on development of B&C?

And I bet a kind of development roadmap would be welcome by the funders who became shareholders of the corporation.
I'm almost sure there is a kind of internal roadmap already which might be quite detailed in terms of tasks, dependencies, time frame, etc. (for basic project management things or whatever).
Otherwise it wouldn't have been possible to calculate the amount of money required (at least $200,000 for the basic version of the exchange) for this endeavour.
A roadmap with some milestones could be part of the website - that would be attractive for both current and (possible) future shareholders.

Do you have twitter or website ready?

[BCExchange]

Do you have twitter or website ready?

Yes, we have a twitter account.

Our initial website content is complete. We will be placing it at bcexchange.org. We have the domain and hosting resources, but there are a few issues to work through in regard to configuring hosting. We expect to have it up very soon.

Would it be possible to get say monthly updates on development of B&C?

I certainly expect you will see visible progress and updates at much shorter intervals.

There has been a concentration of holidays taken by team members the last couple weeks, so progress has been slow within that time interval. I expect we will see quite a bit of progress over the next month, although I know most team members have additional holidays scheduled.

We have two independent iterations moving forward right now. Sigmike is working on the reputation voting system along with its associated block reward as detailed on pages 14 and 15 of the design document. John (aka erasmospunk) will be working on the other voting features unique to B&C Exchange as detailed on page 3 and 4 of the design document. When complete, these changes will be deployed to our publicly available test network, but will not be added to the production network until enough development has been completed to make the exchange fully functional.

When those iterations are complete, we will begin implementing the individual message types unique to B&C Exchange which are described in detail in the design document. Each will be implemented in our public test network when complete. Here is a summary of those message types:

1. Reputed signer deposit public key list
2. Non-reputed signer deposit address request
3. Non-reputed signer withdrawal address request
4. Order
5. Order validation
6. Fill (not signed and no transaction fee)
7. Fill validation
8. Fund transfer
9. Cancel order
10. Withdraw from deposit address
11. Pairing of BlockCredit and BlockShare addresses

We will start with forming the message pairing BlockCredit and BlockShare addresses and client processing of that message. Next will be the reputed signer deposit public key list. Then we will add the non-reputed signer deposit address request message. We will continue to add the rest of the messages to testnet one at a time in the approximate order they would be used in typically.

When the bulk of the messages have been implemented we will begin developing the web interface.

If additional funding is received, we could see additional goodies such as an Android interface that simultaneously functions as a wallet for assets being traded.

That would be nice to have!

By the way, I easily envision B&C Exchange be used as the first decentralized cloud wallet for any crypto assets and currencies.
Thus, people that have no interest in trading would have a reason to use B&C Exchange.
In other words, we could see 2 services:
1) Exchange
2) Wallet

Perhaps we could even think about charging for 2) as well.

I fully second your assessment about BCE offering a wallet service. I've written my take on this at another place (https://discuss.nubits.com/t/passed-motion-to-provide-seed-funding-for-b-c-exchange-a-decentralized-exchange-built-on-the-peershares-platform/2001/539):

Via BCE exchange web sites you effectively can create something similar to e.g. blockchain.info, but in an improved version:
Web access to BCE provides BCE with a kind of online wallet capabilities - similar to blockchain.info.
Transactions (e.g. withdraw) can be executed using a web site - similar to blockchain.info.
This requires coins to be available in a multi signature deposit address - assumably better security than at blockchain.info (does blockchain.info support multi signature addresses and if what level?).

You can execute payments with all coins supported by BCE by creating a withdraw (to the payment deposit address) on any BCE exchange web site - that's way more flexible than at blockchain.info which only supports BTC.
And if you don't have enough BTC, trade some of your deposited LTC or whatever first - that's way more flexible than at blockchain.info.

But the major benefit over central wallets is this:
there's no risk to get your funds seized by taking down a central service or stolen by that central service.
The central server as single point of failure is gone.
All relies on the (distributed) reputed signers which can't be tracked easily if ever.

For the wallet service there's a charge: all transactions that utilize the BCE network as a wallet service require transactions; they have a size and cost BKC

Great! Are we also going to see additional holidays scheduled when you collect even more money?

You said it all.
About the wallet charges, tks for reminding me. The business model is natural.

Thank you very much for that overview! Can't wait to see it evolve!

b&C exchange, a wallet?
I am very interested in the off chain trade among B&C exchange users. Build our own paypal business???

[JordanLee]

We now have an OS X build available for the B&C Exchange client. Sorry for the delay on that.

[masterOfDisaster]

For those who might be interested to build bcexchanged on a RaspberryPi (running Raspbian).
After initial problems to build a bcexchanged on my RaPi2 I tried again.
Here's a dcoumentation of my steps:

Code:

sudo apt-get update
sudo apt-get install libcurl4-openssl-dev #libcurl is required to build from the source, although not stated in doc/build.txt; make sure to have all other dependencies installed
mkdir ~/bce
cd ~/bce
wget https://bitbucket.org/JordanLeePeershares/bcexchange/get/e472f471107c.zip
unzip e472f471107c.zip
cd ~/bce/JordanLeePeershares-bcexchange-e472f471107c/src
sed -i 's/USE_UPNP:=0/USE_UPNP:=-/' makefile.unix #disables UPNP; I don't have the dependencies installed and don't need UPNP
make -f makefile.unix

Et voila, bcexchanged ready after some time (thanks to the RaPi2 being fast as hell compared to the RaPi1 )

Tried starting it and it worked

Code:

bcexchanged --daemon
B&C Exchange server starting
Error: To use the "-daemon" option, you must set a rpcpassword in the configuration file:
 /home/pi/.bcexchange/bcexchange.conf
It is recommended you use the following random password:
rpcuser=nurpc
rpcpassword=bVCSDYtSZyo9SNIw31O10bRa47Y9c8qO8mJT4N0cJSQf

[masterOfDisaster]

Update: bcexchanged running stable on my RaPi2 for over two days.

Code:

bcexchanged getinfo
{
    "version" : "v3.0.0-unk-beta",
    "protocolversion" : 2000000,
    "walletversion" : 1,
    "walletunit" : "8",
    "balance" : 0.0,
    "newmint" : 0.0,
    "stake" : 0.0,
    "parked" : 0.0,
    "blocks" : 37639,
    "moneysupply" : 208540.1054,
    "connections" : 8,
    "proxy" : "",
    "ip" : "obfuscated",
    "difficulty" : 0.00038899,
    "testnet" : false,
    "keypoololdest" : 1438334508,
    "keypoolsize" : 101,
    "paytxfee" : 0.01,
    "errors" : ""
}

And it's very friendly to the RaPi2 doing that (in terms of resources):

Code:

 PID USER      PR  NI  VIRT  RES  SHR S  %CPU %MEM    TIME+  COMMAND
18433 user      20   0  214m 110m  42m S   5,6 11,3 256:00.22 bcexchanged

Wow, I suppose there is no purpose in beating a dead horse, but I'm really surprised that people were turned off by having to hold NuShares.

[statdude]

What is the relationship of this and Nushares?

[masterOfDisaster]

Not sure what you mean. Who had to hold NuShares? Maybe you misunderstood something?
And where's the dead horse?

What is the relationship of this and Nushares?

Have you read the initial post in this thread?

[...]
B&C Exchange, short for ​Blocks & Chains Decentralized Exchange[...]

will be developed by the same established team that has directed Peercoin and NuBits development, a group that includes well-known cryptocurrency experts such as Jordan Lee and sigmike. The experienced team of over ten contributors has successfully led three prior projects (Peercoin, NuBits, NuShares) into the top twenty-five assets by market cap on coinmarketcap.com.

"Not sure what you mean. Who had to hold NuShares? Maybe you misunderstood something?

He probably meant the original offer when this thread launched, where BKS was going to be directly mirrored to NSR.
