nanomsg is a real zero-copy msg server

Zero-Copy

While ZeroMQ offers a "zero-copy" API, it's not true zero-copy. Rather it's "zero-copy till the message gets to the kernel boundary". From that point on data is copied as with standard TCP. nanomsg, on the other hand, aims at supporting true zero-copy mechanisms such as RDMA (CPU bypass, direct memory-to-memory copying) and shmem (transfer of data between processes on the same box by using shared memory). The API entry points for zero-copy messaging are nn_allocmsg and nn_freemsg functions in combination with NN_MSG option passed to send/recv functions.

and it support mode "bus",  http://tim.dysinger.net/posts/2013-09-16-getting-started-with-nanomsg.html

so I write a simple demo for howto implement a p2p network based this.

wish this can help improve the p2p network's efficient.

Glad to see poloniex replace btc38, it's a key factor for BTS's success.
BTC38 can't controll the price so easy now.

I will try to tell them about bitshares, wish I can speak clearly.

when I travel to other country, the first thing after arrive is exchange some money,
then buy a mobile card, and a traffic card.
the exchanger's rate is really very high at airport.

so if a shop can sell mobile card and traffic card with bitUSD,
it will be very helpful, I don't need to exchange at airport.
I only need print a paper wallet, scan the paper, and get my mobile card and traffic card.

This save my money, and my time.
we should do this at all travel city.
you'll become a rich man if you have such a shop

any thought?

for me, the most important thing from BTS2.0 is
again, we have a company, a core team, a leader, who will take responsibility, who will coordination all things.

keep fighting

for now, if I short cny, I use double value BTS as collateral, borrow CNY to buy BTS.
this means I think BTS price will increase against CNY.

but If I think SHENZHEN's price will increase against CNY, what can I do?
first I need to short CNY,  I use double value BTS as collateral and sell out CNY.
second, I need to sell BTS to get SHENZHEN, hedge the risk of BTS against CNY.

this is very complex, so I have suggest to improve it.
I can use double value BTS as collateral, and sell out CNY for SHENZHEN directory.
the command like:
short 1000 BTS as CNY to BID SHENZHEN.

then, all short should collateral BTS. you can short CNY for SHENZHEN, or short SHENZHEN for CNY.

I don't like the idea to use CNY as collateral, because CNY is not enough to use as collateral,
it need to use as cover order, or for payment.

any thought?

I want to change https://wallet.btsbots.com to light wallet server
can anybody help me what should I do?
how to use the BTS JS lib for browser?
what service should implement for the light wallet server?
many thanks!

I am writing a web wallet, based python flask,
it's not a light wallet.
it depend a wallet backend to provide rpc call.
it run a web server at local host,
update the browser in real time throw web socket.
I am not family with User interface.
please join me if you are good at web develop.

you can try the demo version now.

        "user": "alt",
        "password": "alt"
