Ropsten 0xa9e001bebe4b281f7229b0305f553ab3c511fef5
Live 0xa15c784319fa96d3E36cFE97fbadD89Ec704A8dc

ITT's extend the ERC20 API with:

buy(uint price, uint amount, bool make) sell(uint price, uint amount, bool make) cancel(uint price) withdraw(uint ether) 
and other ancillary exchange state getters (see Github repo for full API) such as :
etherBalanceOf(address holder) getBook() getOrdersOf(address trader) spread(bool side) 
The intrinsic exchange functionality works on a FIFO matching maketaker algorithm. A new order may be iteratively filled by multiple make orders on the book or if unfilled, can be put on the book itself as a make order.
ITT demo contracts have been deployed on the Ropsten test chain on which a number of Buy and Sell orders have already been placed for you to play with. The demo ITT and future, more functional ITT's can be can be interacted with using the front end DAPP ITTDesk.

Use Cases

This demo ITT serves to demonstrate the exchange functionality of a basic ITT contract and does not have much intrinsic value in the token itself beyond being a purely speculative coin.
The ITT API and base contract are open source and offered to the community in order to extend or attach value adding functionality to the token side.
As is, crowd funding and token sales become as trivial by simply placing ask orders (see Self Funding below).
Better still would be to extended ITT functionality to make a 'Payable ITT' which becomes a simple but highly versatile pay to an unknown many mechanism which can distribute payments according to proportional holdings. Such holdings might represent shareholders, a rewards system or perhaps be used to fund and manage a DAO's project funds. (I do have a Payable ITT but will not likely release it until the community has confidence in the basic ITT contract)
Other value adding developments might be to couple ITT's to fiat currencies for truly low friction decentralised forex.

Current State of Development

As deployed, the ITT Demo contract is yet to undergo extensive testing and formal verification. It appears to work as intended (unless compiled with 0.4.5+commit.b318366e! My first launch attempt drove me crazy until that bug was announced). The contract on both chains have been verified on etherscan.io etherscan.io.
The ITTDesk app is very much in alpha release, minimalist and clunky in it's function. It is written on Meteor and attempts to use Mist styling and elements. Probably best just to clone the repo and run it up in Meteor at this stage. It features intelligent ask/bid/buy/sell trade buttons to assisting in validating user inputs in the order fields.
I am not an experienced web developer, so feed back, suggestions, criticisms are most welcome. In particular, I've not been able to work up the filters without causing browser timeout.

How does it work?

The order book utilises a mapping of 'Circular Linked Lists (CLL)' from the LibCLLi library to order and lookup the booked prices and iterate the FIFO's at each price. Each FIFO in the mapping is keyed by its price and holds all the addresses of traders who have made orders at that price. A trader can only have a single order at any particular price. An attempt to book another order at the same price will adjust and put the order at the back of the FIFO queue. This prevents FIFO hogging in which a trader might otherwise starve other orders by continually topping up their own.
A second trivial mapping holds the actual order amounts. It is keyed by a SHA3 hash of the trader's address with the price of the order (and is actually what limits the trader to one price, one order).
The CLL's heads are static at mapping key '0'. To use as a FIFO, nodes are simply inserted previous to the head and removed from next to the head. A FILO (stack) can be implemented with equal simplicity.
In the case of the price list, the links either side of the head are the highestBid (previous) and lowestAsk (next) making the head node itself the market spread. The price list is artificially bound to minimum (uint 1) and maximum (uint 2**128) prices. New price nodes are inserted relative to the head (spread) after iterating through an order search.
Looping operations in Smart Contracts can be bug prone and costly, especially with state mutations in each loop as in the ITT's matching algorithm. For this reason, the order matching loop is dynamically limited by the gas supply from msg.gas and will exit with a partially filled order rather than throw it. The remainder does not get put on the book as a make order as it would cause a bid/ask collision at that price. Because of this looping, gas cannot be estimated and it is up to the trader to consider the costs and adjust the amount of gas prior to ordering.
The matching algorithm is not without architectural efficiency however which almost halves the number to calls to STORE by virtualising (caching to memory) the taker's state variables prior to the matching loop and writing back to store once the matching and making operations exit.

Security and Resilience

ITT's hold ether balances and therefore are presumed to be targeted by hacking attempts. A number of security features and practices have therefore been programmed into the contract.
All external or payable state mutating functions are 'reentry protected' by a mutex which is set and cleared in the internal function safeSend(), which is called only by the public function withdraw(). This practice ensures a single entry and exit.
The architecture also separates entry validation logic and parameter preparation which is kept in the external/payable functions, from state mutation logic which is kept in the internal functions. This allows for a secure, flexible, inheritable API/interface layer from which to extend the contract while keeping the basic ITT internal functionality the same.
In the ITT Demo, the default function is unimplemented and therefore throws if payments are sent to anything other than the payable buy() function.
Attention must also be drawn to some rather unconventional use of uint math in the matching loop. Elsewhere, the contract uses explicitly safe maths functions, however the nature of an exchange function requires numerous inverse and signed integer operations. It was found that casting between int and uint became an onerous task with potentially unpredictable outcome and a design decision was made to simply treat uint as signed within the matching loop. In this case -1 == 2**256-1 and is used in multiplication to change the sign of trade amounts during matching.
In light of the signed uint adoption, a further mathematical constraint was placed on the maximum price and amount allowed being 2**128 which prevents any multiplication overflows.

Testing

Given that this contract is Proof of Concept deployment primarily for public review, it should be considered insecure. It has been tested for functionality but no exhaustive testing regime or formal verification has been put against it. It is undeniably a big ugly contract with complex logic and so should be viewed with suspicion.
Interacting with the Live contract is thereby at your own risk!

Self Funding

Being the deploying owner of this Demo ITT, I am granted the full balance of tokens and have placed both ask and bid orders as examples. Purchasing my Ask orders on the Live chain does transfer real ether to my balance and so I am trailing this as a channel for funding my development efforts rather than chasing bounties, competitions, donations, (a real job) or what have you. If you buy tokens here, you could consider it as a much appreciated donation which you might also be able to return a speculative profit from! It would certainly make my life easier. :)

Who Am I?

My name is Darryl Morris AKA o0ragman0o. I'm an independent (and some what isolated) Australian Ethereum developer. Though fairly quite, I've been following Ethereum developments since November 2014 (PoC 6) and have been small time mining since Olympic, though not now with expensive Australian electricity. I am best known on [forum.ethereum.org](forum.ethereum.org) where I am a mod. I've been crypto aware since 2009 when I tried bitcoin in it's infancy. I got 71/70 marks for Griff Green's notorious 'DAO Ninja' homework though obviously needed 72 to recognise the complex of vulnerabilities in that code!
My interests are in developing delegative democracy technologies with which to render all politicians obsolete (particularly ones beginning with 'T'). To that end I've developed the ITT contract as a funding component of a democracy DAO framework I call 'Ethenian DAO'.
Looking for interested collaborators.

Trade.io is gonna make a headlines in 2018

To some friends of mine, those who already know of trade.io, and wondering to keep up with trade-token (TIO) they have bought.
Last year in 2017, trade.io came out with ICO, also the first time for the Liquidity Pool (LP) to be presented. LP is a great feature but there are many other things to TIO than those that meet the eye.
  1. First of all, TIO is the utility of a full-fledged exchange. It is developed by people from the financial industry and not just tech industry. These guys know what a trading platform should look like and how it must function. The platform I believe will quickly become a platform of choice by most crypto traders. Hence this is going to drive the value of TIO as utility token for the platform. Just if you read one of their post, and the feedback from the Beta Testers of the demo exchange, the platform will have a full suite of technical indicators and a customizable gadgets UI… not just a few like most platforms out there. There is a long list of features and functions that have been implemented and considering from community idea and from beta testers’ suggestions.
  2. Trade.io is not just a crypto exchange. Their plan is to go live starting from cryptos and eventually with regulated licenses, based on white paper and their announcement, the company plans to add other assets classes such as forex, CFDs and etc. To me, this is a big game changer. This says, the management knows what they are doing and have foresight. you see cryptos go through waves of ups and downs, it’s so cool that during down times in cryptos like now, TIO still keep its own pace, and trade.io allows its clients to be able to trade other assets. Just look at the forex market and you will see how small crypto world is. If we take a footstep forward to forex with TIO as utility token along with BTV, our exchange will be the best.
  3. Trade.io is also planning on being a full-fledged exchange that takes other companies “public”. As we have seen, for now they offer other projects to launch their ICO on the exchange through trade.io, this will very quickly progress into offering companies to go public on exchange in the traditional manner to but cutting out the big advisory and exchanges fees of traditional exchanges.
  4. LIQUIDITY POOL. Guys, for God’s sake read and understand what they trying to do, because once you do, you will not sell your TIO! When trade.io says they plan to disrupt trading, with a distributed liquidity pool where everyone is treated equal, now you will see all these brokers and funds leaving their prime banks for liquidity and use the pool instead. THIS IS when you will see TIO hitting the crazy $500 to $1000 marks… Don’t quote me now but you will because this is what I feel.
  5. TIO demand will be driven by massive demand and lack of supply, why? It’ simple, most people will lock their TIO in pool to gain profits, circulation of TIO in open market will be lesser, demand will be driven by the following
The above are just few reason why me and my group loaded on TIO when possible. We are now gonna HODL till all the above comes forward.
Last but not least, the team behind this project is committed, this project is built to lead.
The best is not yet to come, but it is really close! So to the team of trade.io: We are with you, as always, the company will set a great milestone soon, because you have all our beliefs, our encouragement, and our supports!
This is referred from the message of a user (cryptovision) in our Telegram community.

The era of artificial intelligence: how robots manage capital

The era of artificial intelligence: how robots manage capital
Interview with Alexander Tatarsky, creator of the quantum fund
How well do you know artificial intelligence? Perhaps you have never heard of it, or maybe it’s quite the opposite and robots are already managing your capital.
We were able to interview Alexander Tatarsky — an experienced trader, co-founder and financial director of the Mercury Foundation — a fund that manages capital through A.I.! Alexander introduced us to the concept of his organization and explained the unique idea behind the project.

https://preview.redd.it/bulvn62tuw021.jpg?width=700&format=pjpg&auto=webp&s=7c6357c83fe7c7afd904a8e9718447801fbdc8a1
Alexander, why did you start trading? How did you start and why did you decide to choose this particular field?
Many people know that the Chinese word “crisis” consists of two hieroglyphs. One means “danger”, and the other one — “opportunity.” I considered a global financial crisis of 2008 an opportunity. That’s when I began my professional career in the financial markets. Before those events, I was always very interested in economics (thanks to my economic education!) and financial markets, but I focused on 2 aspects: first is financial markets as an instrument of global management of peoples and their well-being, second — financial markets as an example of the fundamental laws of nature. I always wanted to get closer to understanding the essence of these processes.
However, until 2008, I was just a curious observer. I read books, watched major events, learned to compare facts. I was running a business that had nothing to do with the markets. The events of 2008 encouraged me to make my first profitable deals. And then I realized that this field is not only about self-development and curiosity — it could also become a source of permanent income. With the right approach, this income can be much higher than in other sectors of the economy. So the choice was made.
What were the reasons for creating an Investment Foundation managed by artificial intelligence?
Anyone who is professionally engaged in money management considers automation at some point. Computers are much more efficient than human when it comes to assets management. Robots are taking over, so it was a logical step for us. From the very beginning, we realized the inferiority of the ready-made solutions on the market and did not even consider using other people’s services. We could use the A.I, and we did. It was actually not even a question, it’s like asking an artist — why are you painting? Because we are the best at managing money.
What is the market share (in particular, on cryptocurrency market) of the investment funds (including funds managed by artificial intelligence) and how do you handle the demand?
If we talk about traditional financial markets, then, according to the latest data, the share of investment funds in the total volume of transactions amounts to 70%. At the same time, quantum funds account for at least 27% of all transactions on US exchanges. As for the cryptocurrency market, they are so riddled with fraud and unrealized projects that we have long since ceased to care about the competitors.
There are many ordinary funds, but 80% of them close in a year and 95% of them — in three. We do not consider them competitors, as we are focused on long-term work. All their clients will eventually come to us. In long-term, the manual traders do not stand a chance against the robot.
Are there any companies similar to yours in the world?
Yes, sure. In our industry, only a few succeeded in achieving the degree of automation that we have. The most successful of our colleagues use qualitatively different algorithms that still require regular manual testing and customization. In most cases, those “algorithm factories” constantly have to adapt to the new market conditions. Our algorithms require human participation only at the development stage. Simply put, in most cases, operators with remote controls always follow their robots, but our robot can walk on its own.
The market offers a huge number of different robots that promise to increase your capital in Forex, binary options, cryptocurrency. How are you different from them? Is it possible to earn money with such robots?
Yes, certainly. If you are good at trading and investing. If you have clear money management rules backed by math. If not, you can only lose. And robots have one more limitation — they cannot bring you the profit all the time. Such robots offer a huge number of strategies, half of which is profitable, and the other half is not. Because a person is ultimately responsible for choosing strategies. That is, it is not the robot that makes the decisions, but the user who sets the trading rules. In some cases, it helps to earn quickly, and in others — to lose quickly. Such robots do not guarantee earnings, they only ensure fast trading. We have a radically different approach. Bruce Lee said: “I fear not the man who has practiced 10,000 kicks once, but I fear the man who had practiced one kick 10,000 times”. Therefore, instead of ten thousand strategies, we have been developing only one strategy for several years.
The robots you are talking about are the first level. There are many of them and to me they are useless. Among our competitors, there are funds that trade in traditional markets using second-level robots. There are not many of them, but they all deliver consistently good results. One of the leaders in our industry is the Medallion Foundation, created by Renaissance Technologies. For several decades, their mathematical model has been continuously multiplying their capital.
We consistently implement the same model of asset management, completely removing a person from decision-making process. Development will take a few more years, but even now, our robot is already trading at the professional level. The robot needs a person only for controlling and learning new functions.
Some believe that technical analysis does not apply to cryptocurrency, what do you think about this statement?
I actually do not care; it is rather a question of how competent is the person who said this. If it works for you, you can use it. I think you will agree that a professional can play even on one string, and the amateur can find a thousand reasons to give up. The only thing I can do is ask in return — what can the market offer instead of technical analysis? Intuitive news trading? Fundamental analysis? Neural network?
Technical analysis is a complex discipline and it takes a lot of time and mental strength to fully master it. It could take a trader 10 years to learn it. Not everyone succeeds, so technical analysis does not work for everyone.
I favor a more specific approach: if it doesn’t work for someone, they should figure out why, because it is working for us quite well.
Where does your Foundation operate?
We advertise ourselves as a global foundation. In today’s world, good business has to be global. Among our clients are representatives of the Russian Federation, the European Union, Great Britain and China. We continue to expand our reach. As for trade, over the next 6 months we will be able to manage capital on all largest exchanges of the world.
Why is there a minimum deposit amount of $ 10,000?
There are several reasons. First, we need funds to maintain client accounts. We do not charge a monthly fee, only a percentage of the profits. Therefore, the size of the deposit has a lower limit.
Second, $10k is not much for our target audience. It also acts as a filter that shows the solvency and how serious the intentions of a potential client are. We do not target the mass market and do not deal with dumping. On the contrary, we provide long-term, high-quality services for those who can afford it.
Third, the robot independently manages risks and simultaneously controls all portfolios. We don’t like it if someone can’t enter the position because the share calculated for him by the robot is not allowed on the exchange due to restrictions.
Are there any differences in the management of different amounts of investment? If yes, what are they and are there any similarities in the management of investments of one quantitative segment?
Our job is to describe all the differences with strict mathematical formulas and test them thousands of times under all possible conditions. Therefore, there is no big difference for us between a 5 mln purchase or 5k purchase. Everything is described, tested, calculated, everything works.
Differences in the management of large capital are even more drastic. The psychological factor in this case becomes critical. The same trader managing a demo account or a million dollar account will behave like two completely different people and make fundamentally different decisions. Our task is to completely eliminate the human factor from the money management process.
What are the chances for new instruments to get into the Foundation’s portfolio? What is the basis of the selection of certain tools? Are there any common priority tools for different segments of investors?
Any promising liquid instrument can be included in the portfolio of the Foundation, and the choice depends on many factors. The robot evaluates and filters the instrument on the basis of special algorithms and determines the share of an asset in the portfolio based on the results of the evaluation. All decisions must be mathematically justified, taking into account the analysis of the maximum possible amount of data. The more data on the instrument we have, the higher the quality of the decisions made and the share of the instrument in the portfolio. The choice does not depend on the category of investor. If the instrument is promising and liquid, all our clients will get profit.
Can you tell more about the terms of settlements between the Foundations and investors?
If someone in our market guarantees you a good profit and even specifies when you could get it, then I in turn guarantee that this is a fraud. We are most interested in customer profits, as this is the only way to offset the costs of managing his account. Imagine the following situation:
The new client opened a 10k deposit and a month later, he had a total of 12k in his account. At the beginning of next month, we will ask you to transfer us 1k as a fee. 11k remains on his account, but a month later, suppose, unsuccessful deals were made and there is 10k on his account again. In this case, we do not require any payments until the deposit exceeds 11k.
Suppose a month later he has 12k again. Then we will charge 50% of the difference between 11k and 12k, i.e. $500. The fact that the entire team of our foundation has long transferred the management of all its assets to our robot could also count as a guarantee. We have a direct motivation to make trading as successful as possible. We do not use the services of other funds or managers. And the second fact is that the portfolios of all clients, including our personal ones, are managed simultaneously.
Can you share the success stories of the Foundation?
We want to implement a demo account for this purpose. We plan to fill it with transactions and statistics from 2017, copied from real accounts, but without disclosing personal data. The demo-account will include a history of the average client from the beginning of 2017.
It will explain how the robot trades and what profit you can expect from it.
Do you believe that private investors, to some extent, are competitors to investment funds? What, in your opinion, is it more efficient and profitable: being a private investor or investing with funds?
No, we consider them not competitors, but clients. The vast majority of our clients already have experience in investing. Beginners often think they are the smartest, that they don’t need to pay someone 50% of the income when they can easily buy and sell themselves. I admit that in the short run a private investor can earn more than a robot — but definitely not over a long period. The robot ensures a stable result day after day, year after year, while people are prone to stress, illness and psychological weakness.
Also, funds, compared with private investors, have more compelling ratio of risk and return. At some time, a private investor may gain the same profit as a fund. However, the fund will achieve the same profit with much less risk. My money is controlled by a robot, although I believe in my capabilities as a trader.
Does the Foundation have an affiliate program?
Yes, we have an affiliate program, and at the same time, we are interested in collaborating with specialists for mutually beneficial cooperation. For example, we could consider providing service for the service for really good experts in design, advertising and marketing. If you have such specialists, let them send me their proposals and CVs. See contact details on our website.
What kind of future do you see for ordinary investment funds and funds like the Mercury Foundation?
It is clear to me that the share of funds managed by robots will grow steadily. Most likely, in a couple of decades only old-timers will manage money manually.
Robotization applies to all spheres of life and investment has already come into play. For example, the head of Japan’s Government Pension Investment Fund — the world’s largest pension fund — believes that artificial intelligence will soon completely replace asset managers. And I fully agree with him.
And the largest hedge fund Bridgewater Associates is developing a decision-making algorithm that can replace all management personnel over time.
How do you look at the cryptocurrency market from a global perspective? Will the Bitcoin climb to 20,000$ again? And what will happen to the altcoins?
If we talk about the long term prospect, like 3–5–7–10 years, then I’ll say that today we see the early stage of the cryptocurrency market. Over time, its capitalization will be measured in trillions of dollars. The best projects of this field will become an integral part of our lives. Many of them will become new Google, Facebook, Apple and Amazon.
However, this will happen gradually. In order to become a mature sector of the economy, this market will have to go through many challenges. It will face issues of legislative regulation and technical problems. The scaling and bandwidth issues of most networks are still relevant, as well as legal issues. Most states are just beginning to explore the risks and opportunities associated with these technologies. And the promotion of such technologies is still very dependent on states and supranational bodies. If we talk about the short and medium terms, the prospects are not very bright.
I think that in the near future the bitcoin will certainly not reach the 20,000$ mark. We are witnessing the strongest bear market and must act accordingly. The time for positive medium-term forecasts has not yet come. The industry was severely overcrowded in 2017. There was too much hot money, many economically unfeasible projects and excessively high expectations. The market will need time to stabilize and consolidate. Most likely, we are in for a rather complicated and dangerous period of instability in the market. Obviously, this will be accompanied by some cleansing of the market from weak, incompetent and unclaimed participants.
This is a necessary stage on the path towards development. I think that 80% of altcoins known to us will depreciate and disappear in the next year or two for objective reasons. It will be a time of natural selection. However, strong players will only strengthen their positions in the market. Unfortunately, there will not be many of them. Therefore, in the near future, all investors will need to take a good care of the management of their portfolios. Despite the rather grim short-term and medium-term expectations, there will be some positive developments on the market. Some cryptocurrencies are likely to exceed their all-time peaks next year. And some will just look stronger than the market. This will be enough to generate profitability even under such difficult conditions. Therefore, the main task for the near future is to manage risks in a competent and very conservative manner and select the best ones on the market for investments.
From a professional point of view, what would you wish to partners of our club?
Depends on their goals. If they invest for the sake of emotions, then I wish them good luck and health. If they do it to earn money, I advise you to consult with professionals. This applies not only to investments, but also to any area of life. If you want the task to be solved as accurately as possible — always contact the best professionals available. And always keep learning. Your knowledge is your most reliable asset.
What books would you recommend for beginner traders?
If you decide that you are ready to turn trading into your profession, then start eagerly exploring everything available to you. Everything about financial markets, about macroeconomics, about psychology, about analysis and forecasting. Do not forget that money management skills play a huge role here. Ralph Vince will help you figure it out. Even if your analysis of the markets is very good, you will lose everything eventually if your money management skills are subpar. Now is a great time to learn, you have hundreds and thousands of books available on all aspects of this profession. Someone will enjoy the works of John J. Murphy or Jack Schwager, someone will learn from William D. Gann or Robert Prechter. And remember: knowledge is more important than capital!
We thank Alexander for such a detailed story about the Foundation, as well as for his sincere desire to share his opinions and forecasts. If you want to entrust the management of your funds to the Mercury Foundation, type “I want to invest in the Mercury Foundation” in the personal messages of the group.

For Review: 'Intrinsically Tradable Tokens' (ITT's) are their own exchange

For Review: 'Intrinsically Tradable Tokens' (ITT's) are their own exchange

Introducing Intrinsically Tradable Tokens, ERC20 compliant tokens in which you can buy and sell directly from the contract.
Ropsten 0xa9e001bebe4b281f7229b0305f553ab3c511fef5
Live 0xa15c784319fa96d3E36cFE97fbadD89Ec704A8dc

ITT's extend the ERC20 API with:

buy(uint price, uint amount, bool make) sell(uint price, uint amount, bool make) cancel(uint price) withdraw(uint ether) 
and other ancillary exchange state getters (see Github repo for full API) such as :
etherBalanceOf(address holder) getBook() getOrdersOf(address trader) spread(bool side) 
The intrinsic exchange functionality works on a FIFO matching maketaker algorithm. A new order may be iteratively filled by multiple make orders on the book or if unfilled, can be put on the book itself as a make order.
ITT demo contracts have been deployed on the Ropsten test chain on which a number of Buy and Sell orders have already been placed for you to play with. The demo ITT and future, more functional ITT's can be can be interacted with using the front end DAPP ITTDesk.
This demo ITT serves to demonstrate the exchange functionality of a basic ITT contract and do not have intrinsic value in the token itself beyond being a purely speculative coin.
The ITT API and base contract are open source and offered to the community in order to extend or attach value adding functionality to the token side.
The simplest example of an extended function ITT might be to make a 'Payable ITT' which becomes a simple but highly versatile pay to an unknown many mechanism which can distribute payments according to proportional holdings. Such holdings might represent shareholders, a rewards system or perhaps be used to fund and manage a DAO's project funds. (I do have a Payable ITT but will not likely release it until the community has confidence in the basic ITT contract)
Other value adding developments might be to couple ITT's to fiat currencies for truly low friction decentralised forex.

Current State of Development

As deployed, the ITT Demo contract is yet to undergo extensive testing and formal verification.
The ITTDesk app is still minimalist in it's function though is written on Meteor and attempts to use Mist styling and elements. I am not an experienced web developer, so feed back, suggestions, criticisms are most welcome.

How does it work?

The order book utilises a mapping of 'Circular Linked Lists (CLL)' from the LibCLLi library to order and lookup the booked prices and iterate the FIFO's at each price. Each FIFO in the mapping is keyed by its price and holds all the addresses of traders who have made orders at that price. A trader can only have a single order at any particular price. An attempt to book another order at the same price will adjust and put the order at the back of the FIFO queue. This prevents FIFO hogging in which a trader might otherwise starve other orders by continually topping up their own.
A second trivial mapping holds the actual order amounts. It is keyed by a SHA3 hash of the trader's address with the price of the order (and is actually what limits the trader to one price, one order).
The CLL's heads are static at mapping key '0'. To use as a FIFO, nodes are simply inserted previous to the head and removed from next to the head. A FILO (stack) can be implemented with equal simplicity.
In the case of the price list, the links either side of the head are the highestBid (previous) and lowestAsk (next) making the head node itself the market spread. The price list is artificially bound to minimum (uint 1) and maximum (uint 2**128) prices. New price nodes are inserted relative to the head (spread) after iterating through an order search.
Looping operations in Smart Contracts can be bug prone and costly, especially with state mutations in each loop as in the ITT's matching algorithm. For this reason, the order matching loop is dynamically limited by the gas supply from msg.gas and will exit with a partially filled order rather than throw it. The remainder does not get put on the book as a make order as it would cause a bid/ask collision at that price. Because of this looping, gas cannot be estimated and it is up to the trader to consider the costs and adjust the amount of gas prior to ordering.
The matching algorithm is not without architectural efficiency however which almost halves the number to calls to STORE by virtualising (caching to memory) the taker's state variables prior to the matching loop and writing back to store once the matching and making operations exit.

Security and Resilience

ITT's hold ether balances and therefore are presumed to be targeted by hacking attempts. A number of security features and practices have therefore been programmed into the contract.
All external or payable state mutating functions are 'reentry protected' by a mutex which is set and cleared in the internal function safeSend(), which is called only by the public function withdraw(). This practice ensures a single entry and exit.
The architecture also separates entry validation logic and parameter preparation which is kept in the external/payable functions, from state mutation logic which is kept in the internal functions. This allows for a secure, flexible, inheritable API/interface layer from which to extend the contract while keeping the basic ITT internal functionality the same.
In the ITT Demo, the default function is unimplemented and therefore throws if payments are sent to anything other than the payable buy() function.
Attention must also be drawn to some rather unconventional use of uint math in the matching loop. Elsewhere, the contract uses explicitly safe maths functions, however the nature of an exchange function requires numerous inverse and signed integer operations. It was found that casting between int and uint became an onerous task with potentially unpredictable outcome and a design decision was made to simply treat uint as signed within the matching loop. In this case -1 == 2**256-1 and is used in multiplication to change the sign of trade amounts during matching.
In light of the signed uint adoption, a further mathematical constraint was placed on the maximum price and amount allowed being 2**128 which prevents any multiplication overflows.

Testing

Given that this contract is deployed primarily for public review, it should be considered insecure. It has been tested for functionality but no exhaustive testing regime or formal verification has been put against it. It is undeniably a big ugly contract with complex logic and so should be viewed with suspicion.
Interacting with the Live contract is thereby at your own risk!

Self Funding

Being the deploying owner of this Demo ITT, I am granted the full balance of tokens and have placed both ask and bid orders as examples. Purchasing my Ask order on the Live chain does transfer real ether to my balance and so I am trailing this as a channel for funding my development efforts rather than chasing bounties, competitions, donations, (a real job) or what have you. If you buy tokens here, you could consider it as a donation which you might also be able to return a speculative profit from! It would certainly make my life easier. :)

Who Am I?

My name is Darryl Morris AKA o0ragman0o. I'm an independent (and some what isolated) Australian Ethereum developer. Though fairly quite, I've been following Ethereum developments since November 2014 (PoC 6) and have been small time mining since Olympic, though not now with expensive Australian electricity. I am best known on [forum.ethereum.org](forum.ethereum.org) where I am a mod. I've been crypto aware since 2009 when I tried bitcoin in it's infancy. I got 71/70 marks for Griff Green's notorious 'DAO Ninja' homework though obviously needed 72 to recognise the complex of vulnerabilities in that code!
My interests are in developing delegative democracy technologies with which to render all politicians obsolete (particularly ones beginning with 'T'). To that end I've developed the ITT contract as a funding component of a democracy DAO framework I call 'Ethenian DAO'.
Looking for interested collaborators.

Trade.io is gonna make a headlines in 2018

To some friends of mine, those who already know of trade.io, and wondering to keep up with trade-token (TIO) they have bought.
Last year in 2017, trade.io came out with ICO, also the first time for the Liquidity Pool (LP) to be presented. LP is a great feature but there are many other things to TIO than those that meet the eye.
  1. First of all, TIO is the utility of a full-fledged exchange. It is developed by people from the financial industry and not just tech industry. These guys know what a trading platform should look like and how it must function. The platform I believe will quickly become a platform of choice by most crypto traders. Hence this is going to drive the value of TIO as utility token for the platform. Just if you read one of their post, and the feedback from the Beta Testers of the demo exchange, the platform will have a full suite of technical indicators and a customizable gadgets UI… not just a few like most platforms out there. There is a long list of features and functions that have been implemented and considering from community idea and from beta testers’ suggestions.
  2. Trade.io is not just a crypto exchange. Their plan is to go live starting from cryptos and eventually with regulated licenses, based on white paper and their announcement, the company plans to add other assets classes such as forex, CFDs and etc. To me, this is a big game changer. This says, the management knows what they are doing and have foresight. you see cryptos go through waves of ups and downs, it’s so cool that during down times in cryptos like now, TIO still keep its own pace, and trade.io allows its clients to be able to trade other assets. Just look at the forex market and you will see how small crypto world is. If we take a footstep forward to forex with TIO as utility token along with BTV, our exchange will be the best.
  3. Trade.io is also planning on being a full-fledged exchange that takes other companies “public”. As we have seen, for now they offer other projects to launch their ICO on the exchange through trade.io, this will very quickly progress into offering companies to go public on exchange in the traditional manner to but cutting out the big advisory and exchanges fees of traditional exchanges.
  4. LIQUIDITY POOL. Guys, for God’s sake read and understand what they trying to do, because once you do, you will not sell your TIO! When trade.io says they plan to disrupt trading, with a distributed liquidity pool where everyone is treated equal, now you will see all these brokers and funds leaving their prime banks for liquidity and use the pool instead. THIS IS when you will see TIO hitting the crazy $500 to $1000 marks… Don’t quote me now but you will because this is what I feel.
  5. TIO demand will be driven by massive demand and lack of supply, why? It’ simple, most people will lock their TIO in pool to gain profits, circulation of TIO in open market will be lesser, demand will be driven by the following – new people wanting TIO to earn money from the pool, – people participating in all the ICOs and IPOs on the exchange and open market would rather convert their ETH to TIO before contributing to the new projects as the contributions using TIO carries extra bonus and airdrop etc. from trade.io’s ICO clients, – demand for TIO from intuitional traders and brokers as it’s a means of license to access the pool to carry out their own settlements. So, they need to buy TIO just like everyone else to access pool, not for profit share but also for settlements, sort of like GAS for liquidity access. And this, can be huge as the intuitional volumes are tremendous.
The above are just few reason why me and my group loaded on TIO when possible. We are now gonna HODL till all the above comes forward.
Last but not least, the team behind this project is committed, this project is built to lead.
The best is not yet to come, but it is really close! So to the team of trade.io: We are with you, as always, the company will set a great milestone soon, because you have all our beliefs, our encourage, and our supports!
This is referred from the message of a user (cryptovision) in our Telegram community.

NEBULA EXCHANGE; THE BEST PROSPECTIVE CRYPTO EXCHANGE

Greetings ladies and gentlemen, are you into crypto currency trading?, do you experience delay in transaction during trading? do encounter excessive trading fee? have you lost your fund to an Exchange? I pressume you might have experienced such challenges in your previous days of trading on exchange, I bring good news to you because with the Nebula Exchange all this listed problems have been solved, kindly take time to read through my review, also visit the Nebula White and Website for more information.
INTRODUCTION
There is no gainsaying that the invention of Blockchain technology has sprout the interest of many people in crypto currency, this has created the need for more user friendly crypto exchanges where investors can trade their coin/token seamlessly. Crypto currencies exchange is the widest platform to buy and sell coins and although exchanges constantly evolve and improve, there are challenges and problems that must be critically looked into. It is against this backdrop I deem it fit to review Nebula Crypto Exchange project. Nebula exchange is a centralized exchange platform that deals on cryptocurrency exchange and tends to blend the crypto trading platform with updated news, technical analyses from various experts and review from users for a refined trading experience. We believe that users that are just coming into the trade need information beyond the price and volume of cryptocurrencies and we are set to provide them with all the necessary information required to make concrete decisions on investment on cryptocurrencies and appreciate the trade while making huge profits on their investments.
PROBLEMS OF TRADITIONAL CRYPTO EXCHANGES
Lack of liquidity is pushing volatility been the biggest problems facing cryptocurrency exchanges is an endemic lack of liquidity. The lack of liquidity, in turn, makes it hard for traders and investors to exit the market at profitable prices. When trading cryptocurrency, traders often have to up their sale and wait for the order to be filled. However, the fact that many exchanges don’t have a reserve pool means that traders must wait until there’s a willing buyer on the network before their order is filled. Hence, many traders often find themselves trapped in the market beyond the timing of their exit signal.
Transaction Delays Another common complaint of cryptocurrency trading is the delays in almost every transaction. Most platforms are slow to use, all the way from registering an account to making a sale. Most trades need to be mined for a trade to go through, which raises costs for people even higher, on top of the commissions the platforms make to stay in business. As more individuals join the blockchain, it gets slower, and exchanges are regularly stuck in the line sitting tight for endorsement. This at that point means speculators and makes the entire procedure troublesome and unrewarding for each dealer.
Exchange delays are only a portion of the various issues that Price Manipulation Another name for price control is purchase dividers and offer dividers, which are begun by a gathering of people in the crypto showcase, alluded to as whales. In crypto exchanging, price control is the main source of the unpredictability of crypto markets. New financial specialists dependably appear to be on the wrong end of this movement. Numerous unpracticed individuals won't have the capacity to peruse the indications of the purchase divider, and rather, consider it to be a positive cost. Driven by obliviousness and defective rationale, numerous will imagine that the cost will expand, so they race to purchase. Lamentably, this inevitably prompts more weight on little time financial specialists, who think that its difficult to enter the market at a particular value run. While the whales, or huge speculators, can do the control of the market without spending excessively cash. At the point when the price moves in a whale's support, the whale would then be able to move their position and move the value run once more.
Forex And Binary Another issue with digital currency exchanging is the issue of Forex and Binary choices. At the present minute, numerous Forex organizations like EToro and FXPro have recorded crypto exchanging as a possibility for their stages. These crypto postings regularly accompany a get rich speedy mindset that draws a great many unpracticed financial specialists, who at that point wind up losing the majority of their cash inside minutes. Sadly, most forex merchants neglect to comprehend that forex financiers don't take into account the open market. Rather, they go after the benefits of clueless speculators, who utilize them as counterparty. While a few merchants trust that administrations manage the Forex advertise, regularly they overlook that the controller basically tosses in a disclaimer, which adds up to simply only a couple of expressions of caution. Fake News Fake news is an extreme issue for cryptographic forms of money, as these stories can be grabbed by editors in online networking channels and dispersed to a colossal gathering of people. Regularly, these stories are not reality checked and may even contain purposeful mistakes to influence the general's sentiment about a specific kind of coin.

The last rundown of monetary standards the Nebula task will coordinate with isn't yet known.

This, obviously, describes the undertaking from the best side. Ostensible parameters. Every dealer can participate in voting and give and assess a specific task. On the affirmations of the delegates of the undertaking it will be like the assessment devices from Amazon. Thus, a wide range of con artists, ventures without content, will have a powerless rating, which will encourage tenderfoots and even proficient merchants on the planet to make certain decisions about either venture. – Mobile applications.
