**MANDATORY UPGRADE REQUIRED** [ANN] B&C Exchange - All users must upgrade

[Yurizhai]

So, B&C needs two full time developers to get things really moving. Is this to say that without them, progress is currently at an effective halt?

[NuCoinGame]

Progress is not at a halt and the project is still being worked on daily. The advantage of having two full time devs would significantly reduce the time to deliver on the project goals.

[CB_project]

Trading now available?

[NuCoinGame]

Trading is not yet available. 4.0 will support asset voting and reputed signer voting, which is the next release.

[piebeyb]

just wanted to know how this works, at least I was on this thread for more information, cheers

[BadGhost]

Do I understand correctly that by this project you are taking on all of the current exchanges? Meaning that you Will maybe deliver a decentralized exchange for everyone, which will create a multiple websites based on your protocol, however at the same time making all of the existing exchanges archaic.

That means that they should by the time lose all their profits? That is a bold move.

It's bold. But centralized exchanges still are faster at executing transactions, by orders of magnitude in general, than decentralized ones. So there are places for both kind of exchanges.

[...] centralized exchanges still are faster at executing transactions, by orders of magnitude in general, than decentralized ones. So there are places for both kind of exchanges.

I fully agree.
High frequency trading will by design be impossible with B&C Exchange - at least in the implementation that is currently being created.
I have no idea how to bring the speed of a decentralized exchange even close to a centralized exchange, but doubt that it's possible with the currently available tools.

This decentralized exchange is going to have other benefits than speed (just to name a few):

• ability to trade native assets instead of proxy assets (in difference to other decentralized exchanges, same as centralized exchanges)
• high level of security due to multisig with different possible levels (rarely (if ever!) found at centralized exchanges)
• high level of availablity - all trades happen on blockchain and cost BKC; DDoS'ing the blockchain is possible, but very costly as BKC are required for it
• highly flexible ways to access the "account": by wallet application on own computer or through websites, which offer access to the blockchain
• leveraged/margin trading is basically possible
• decentralized escrow services are within reach

Hey everyone. The release for B&C 4.0 is right around the corner. We'd like to gather a small group of community testers to help us prior to making a full release. Preferably people who have BlockShares and have been actively minting.

If you're interested please send me a private message here, or reach out to me on twitter. twitter.com/nucoingame

Thanks!

[Yurizhai]

So B&C 4.0 will allow reputed signer voting and which currencies will be traded on the exchange.

I believe this was touched on deep within this thread, but can someone describe the process of being a signer? Briefly walk us through the set up and day in life of a signer.

I ask because I'd really like to become one.

I'm pleased to be able to announce that we have added Xiaochuan Wu as a Senior C++ Developer to the B&C Exchange development team. Xiaochuan successfully led a team of developers in the creation of the Huobi Bitcoin wallet. I asked him a series of difficult blockchain technical questions related to an upgrade scenario and he answered each perfectly, whereas other previous candidates had displayed mostly ignorance of the intracacies of blockchains. I can certify that he is a blockchain expert, as well as being well versed in C++.

Xiaochuan is on contract as a Senior C++ Developer from March 14th to August 13th, having committed to completing an average of 20 to 30 hours of billable work per week. He is interested in extending past August if funding permits. He is dedicated to B&C Exchange and is not expected to work on NuBits any time soon.

Please welcome Xiaochuan to the team! We now have significant development work on B&C Exchange occurring in North America, Europe and China.

[NuCoinGame]

Welcome Xiaochuan. I look forward to working with you on making B&C bigger than PB&J.

[masterOfDisaster]

Sounds like an impressive application.
I'm keen on seeing B&C Exchange in action.
Welcome, Xiaochuan Wu!

[mhps]

It's great to see the dev team expanding.

Wellcome Eleven!  Is this your product? Quickwallet?

I like this  Off Chain transaction very much!  In our PPC/Nu/B&C community, I guess the consensus is that the blockchain is suitable for settlement network, not good at micropayment. As Sunny King said, PPC is for "Backbone". So our PoS blockchain has no bloat issue, no 1 MB vs 2MB quarrel.

I believe this was touched on deep within this thread, but can someone describe the process of being a signer? Briefly walk us through the set up and day in life of a signer.

I ask because I'd really like to become one.

I'd like to ask additional questions:
is it possible to state hardware requirements for a computer that is suitable for running a signing node?
How much RAM and CPU speed is necessary, how much I/O, bandwidth, etc.?
Is it possible to host a redundant solution (I suppose it's not easily possible, at least not as an integrated solution)?

Is a device like RaspberryPi3 suitable, or do you need more power?

As far as I understand, the reputed signers need to run nodes or have RPC access to daemons of the assets they offer signing for.
Can you please remind me: are only standard wallets supported or lightweight versions as well?
...signers for BTC will have a hard time, if they need to sync over 70 GB blockchain...
