Ethereum is only a few months away and will let us design flexible, distributed smart agents and contracts as well as DACs. There are already platforms such as Open Transactions, BitShares or MasterCoin that support scripting of smart contracts so our discussions will not be limited to theory. 

Let's meet up and discuss practical implementations of:

• Smart contracts

• Smart properties

• Distributed auctions

• Distributed exchanges

• Financial Derivatives

• Assurance contracts

• Decentralised identity

• Reputation systems

• Decentralised lotteries

• ... Sky(net)'s the limit Smiley


You do not have to be a coder to attend. Finance backgrounds would be welcomed as the subtleties of bonds, futures, shorting etc is what will be tricky to model within DACs. It would be great to see some ideas become practical implementations, or at least pseudo code!


4  Alternate cryptocurrencies / Altcoin Discussion / [ANN] Working on a next-gen alt exchange - ideas & comments welcomed! on: January 06, 2014, 02:43:38 PM
************
This project is on ice - ANN didn't gather the traction I would have expected and I'm pivoting the tech towards a hybrid + decentralized model interacting with frameworks like OT or Ethereum. Will repost when I have something to demo to you guys!
************

Hi, I'm currently building a next gen alt exchange and seeking investment to take it beyond prototype phase. The following is a take on the current market and a proposal to deliver an exchange that solves a lot of the pain points currently experienced by traders, casual or otherwise. I welcome all ideas, constructive criticism and the best features suggested will definitely make it into the exchange once it's live!

As of January 2014, the alt market market is inefficient, the exchanges poorly put together. The opportunities for arbitrage are thwarted by rate limited APIs and buggy implementations. As a casual trader myself, and I’ve experienced first hand the ’nginx 502 errors’, invalid balances and general downtimes experienced on cryptsy, bter and the like.

Furthermore, algo traders are simply not present on the alt market as no major alt exchange provides APIs fast or reliable enough to support HFT. Without arbitrage or futures, it’s no wonder we’re experiencing volatility in both the BTC and alt markets.

I’m currently developing an alt exchange that would solve many of the issues currently experienced by traders. Having led the development of enterprise-scale, high frequency transactional platforms in the past, I’ve had personal, hands on experience in scaling high TPS retailer systems in ’always on’ environments. LI profile is linked at the bottom of this post.

The alt exchange I’m currently building is unique in a number of distinguishing, unique ways. But first and foremost its most defining attribute is its ‘real time’ nature, usually reserved to professional traders willing to fork out thousands to gain access to private com lines and dedicated trading stations.

The way I resolved this issue is by ‘pushing’ data to traders rather than forcing them to pull it. No longer do you need to enslave yourself to arbitrary ten second refresh timers or maniacally press ‘f5’ on your keyboard when trying to leverage a bullish market. My exchange proof of concept displays the order book as it stands in real time, to everyone participating. A new ask bid is displayed as it arrives on the exchange, complete with a full refresh of current price, order book depth and OHLC graph. For the tech crowd amongst you, it’s 100% data over the wire.

Furthermore, it:
- Supports most order types you would expect as a trader: market, limit, fill-or-kill, day, stop, and stop limits.
- Allows for HFT/algo trading - it welcomes automated traders as I believe that arbitrage between exchanges will bring stability to both BTC and alts.
- Has a free mobile companion app that leverages the same technology as the full site
- Supports sub 100ms graphing on all KPIs, free of charge.
- Support of all pairs and as they become available - I believe an efficient market will kill off the ‘clones’ that do not bring much value, and do not pass judgment on tech that might revolutionise crypto. PPC > XPM > LTC is a valid trade on this exchange.
- Full screen, single page access to all KPIs that matter to you. No longer will you have to open 3 tabs just to keep track of your partially filled orders. It’s all there in glorious full-page display, and responsively adapts to your screen size to displays as much information as your display will allow.
- Simplified trading interface to allow you to jump in at predefined % of the current coin value - leave your calculator in the drawer, the exchange is doing all the maths for you
- Bot friendly API, welcoming algo and HFT traders - enabling true arbitrage opportunity between exchanges

Icing on the cake, I’m not hiding behind a nickname - my identity is fully known, the exchange will operate completely transparently and will follow all regulations of the country in which its company is registered. My Linkedin profile is : http://j.mp/stual.

Looking forward to hear everyone's thoughts!
5  Economy / Trading Discussion / Is there any truth to this theory on dips before holidays? on: December 24, 2013, 12:13:28 PM
Hi,

On Reddit there's been numerous reference to dips just prior to bank holidays being linked to traders liquidating their positions just before they go on leave.
I.e, institutional traders not wishing to have coins on the exchanges while they are away (and presumably unable to trade).

Would you say there is any truth to this? The recent dip a few hours ago strangely coincides with mid-day in the London city (many enjoy half-days on Christmas eve) and Asia going home from work.

6  Other / Beginners & Help / Hello everyone! Can't wait to join the 'project' discussions. on: December 18, 2013, 04:11:11 PM
Hi! I've recently opened a bitcoin brain trust, which I believe is the first of its kind in London. I don't think I can place links in my first post under this account but it should be easy to derive the URL from my user name Smiley

I look forward to meeting potential partners in this forum. I have also a very specific idea for a project for which I will be seeking funding very soon. Until then you can follow me on Twitter @stephantual.

Cheers!
