The evolution in ERC20 and the era of ERC223

The ever evolving Ethereum Blockchain brought to Cryptocurrency and ICO investors a new gift, the ERC223 a new standard for tokens created on Ethereum. Up until now the newly created tokens on Ethereum public Blockchain should have followed the ERC20 convention. This by all means was a huge success and relief for both token owners and the investors for that token. ERC20 makes sure the behavior of the token on Ethereum is standard with a defined common list of rules. The ERC223 is an improvement of ERC20 protocol, and is backwards compatible to ERC20, meaning every wallet and software that supports ERC20 does work with ERC223. So to get a better picture from this improvement, maybe its better to breakdown how these tokens are created and lets start with the ERC20 tokens.

ERC20 and how does such tokens are created? 

ERC20 protocol allows token owners and developers to create a token that complies with common, essential behavioral rules. The standard is now very popular, specially among ICO investors and their communities. Thanks to ERC20 investors can be certain that the following statement can be true if the token is ERC20:

  • Technically tokens can be accepted by almost all exchanges
  • Tokens are transferable, and all Ether wallets will automatically store the newly created tokens
  • Transactions using that token is done smoothly

A token is compliance with ERC20 if the developer of the token contract implement the following interfaces:

  • The token name with function name, it returns the name of the token.
  • The token symbol with function symbol, it returns the symbol that token will use.
  • The token decimal places, function that returns the unit8 decimals the token uses.
  • How much the owner want to start off with: function balanceOf, it returns the account balance.
  • The amount of tokens in circulation: function totalSupply, it returns the total token supply.
  • The transfer value: function transfer (address _to, unit256 _value), this function is in charge of the transfer events. the function should revert a transaction if the sending account _from does not have sufficient balance.
  • The transfer from: function transferFrom, this function is used for withdrawal workflow, it allows contracts on the Blockchain to transfer tokens on token holder behalf.
  • The crediting permission, function allowance (address _owner, address _spender), it returns the amount which the buyer (_spender) is allowed to withdraw from the owner (_owner).
  • The events: with function transfer (address indexed _from, address indexed _to, unit256 _value) its triggered when a token has been successfully transferred and function approval (address indexed _owner, address indexed _spender, unit 256 _value) this must trigger on any successful call.

 

What did ERC223 has added to ERC20 and what are the advantages?

Initially the idea of ERC223 came to play when the amount of lost tokens on Ethereum Blockchain went sky rocketing, this was due to lack of possibility to handle incoming transactions. Ethereum Blockchain is a leading network for number of lost tokens. Top 8 ERC20 contracts with losses will come up to approximately 3 million USD worth of tokens. how does this happen? once an ERC20 token is sent to a contract that is not designed to work with that ERC20 tokens, the contract will not reject the tokens because the contract does not recognize an incoming transaction. Consequently the token will get stuck the that contract balance. ERC223 will allow users to only send their tokens to either wallet or contracts with the same transfer function, this way it prevents the loosing of the token. ERC223 introduces the function transfer (address _to, unit _value, bytes _data). This function transfers tokens with invoking the function tokenFallback in _to, only if _to is a contract. This will allow the smart contract to actively handle sent tokens. Whereas when an ERC20 token is transferred, the token contract is not notifying the receiver that the transfer has occurred, to that end the address receiver has no possibility to handle the incoming transaction and therefore no way to reject not supported tokens.

A seamless token transfer is another advantage of ERC223 over ERC20. An ERC20 transaction between a regular (not a contract) and contract are two different transactions. There two functions need to be triggered, first the approve function on the token contract and latter the transferForm on the other contract (the receiver). ERC223 has addressed this more efficiently by allowing to use the same transfer function. ERC223 could be sent by only calling the transfer function on the token contract with no if the receiver is a regular address of a wallet or a contract. Due to this shortcut another advantage that ERC223 has is the gas cost, ERC233 consumes almost half as much as an ERC token.

So as discussed above ERC223 advantages over ERC20 comes down to the following points:

  • provides a possibility to prevent accidentally losing tokens
  • Allows users to transfer tokens anywhere (owned address or contract) using one function
  • allows contract developers to manage incoming transactions, contract developers could implement contract in a way that only works with some specific tokens incoming and handling them in a specific way which could also each tokens could be handled in a specific way.
  • ERC223 consumes almost half gas as ERC20

Currently is not possible to upgrade existing ERC20 token contract to ERC223, but if you are planning to create your own maybe its a good idea to go with ERC223.

CEO of Empirica, was among keynote speakers at the CFA Investment Summit

On October 27th, 2017 the CFA Investment Summit, a key event for financial market participants in Poland, took place at the Warsaw Stock Exchange.

The event was organized by CFA Society Poland. The main media partner was the newspaper “Puls Biznesu“. The conference was divided into a series of lectures and panel sessions with the participation of nearly 250 experts from Poland and abroad.

This year’s event began with the presentation of the results of a survey commissioned by CFA Society Poland. The survey was run on a sample of more than 500 financial professionals and its subject was knowledge of fintech issues.

Its results indicate that, when asked about their knowledge of the use of new technology in the financial industry,  only 31% of respondents responded that it was very good or good. The vast majority of respondents (40%) said that they were “neither well nor poorly” acquainted with the topic.

The conference

In the first part of the conference, the speakers focused on what the opportunities and risks the fintech revolution presents, especially for companies and managers dealing with traditional investment advice.

– According to a survey conducted among top experts, they absolutely do not see the threat. Almost 80% think that fintech is not a problem for them, because they are good enough that when conditions change they will adjust and win. On the other hand, for less developed professions that do not require creativity, it is indeed a threat, because these professions will disappear. The ones which stay will be specializations that require creativity, an analytical approach and communication skills – explains Krzysztof Jajuga, President of CFA Society Poland.

The next part of the conference was dedicated to robo-advisory platforms. The panel discussed the difference between fully automated models and hybrid solutions. It was attended by Empirica S.A. CEO Michał Różański, who noted:

There is space for a whole spectrum of advisors on the market – from traditional to fully automated models. Today, in a rapidly changing world, it is hard to predict  how the accents will be distributed. Since now 1 percent of  the population uses financial advisory services, there is a problem with supply/the problem lies with the supply, because it pays off for advisors to advise only the richest . This is the space for automated consultancy.

The founder of Empirica believes that the entrance of the generation of millennials in  the market, increasingly eager to use AI-based (artificial intelligence) solutions, will especially be the impetus for the development of fully automated advisory platforms, which, using a well-tailored user interface, will allow customers with lesser resources to engage more on the investment market. Which, he added, should lead to its greater democratization.

The Importance of Agile Software Development

The strategic value of software to companies continues to grow and businesses are increasingly seeking to software as the technology empowering and differentiating their businesses and products. Software is driving many of today’s key technology trends, such as cloud computing, freedom and social networking. Software embedded in goods can also be currently transforming numerous commercial businesses, such as the manufacturing, healthcare and communications industries. Organizations are challenged to create their business applications and software-driven merchandise faster. Compete, to successfully innovate and grow, organizations require experience and solutions to accommodate to competitive dynamics and customer needs.

Businesses utilize manual procedures and unsophisticated tools, including paper-based tactics and spreadsheets, to manage workflow throughout the software development lifecycle. These techniques are generally more suitable for smaller development projects handled by a team and cannot scale to meet the requirements of businesses and multi-team projects. The waterfall method gained prominence as the way to manage large software development projects. This strategy, which may take many months or years to complete, relies on rigid sequential execution of the many phases of the software development lifecycle, including analysis, design, coding, integration and testing that is final. Enterprises employing the waterfall method frequently structure internal branches around every development stage and utilize distinct legacy software tools for every phase and department, leading to siloed and disparate information, limited transparency and collaboration between teams, and increased risk of misalignment between software development and company initiatives. The next diagram illustrates the waterfall procedure:

 

Agile was introduced by a group of software visionaries in 2001 via a open letter. It represented a methodology for software creation and delivery designed to decrease costs and significantly improve quality, time-to-market and client satisfaction. Agile projects build software

 

Incrementally, in tiny batches, using iterations of one to four weeks which help keep development aligned with changing business needs. Agile is increasingly replacing waterfall processes across several industries because of the results it can provide. According to the Standish Group, software applications developed with Agile techniques have three times the success rate of applications developed using the waterfall process. The Standish Group defines an effective project as you delivered with functions and all the features, on budget, and on time. The following diagram illustrates the Agile methodology:

 

Agile techniques are being adopted by enterprises, replacing and disrupting the legacy software development methods that have comprised the market for application lifecycle software. According to IDC, the application lifecycle marketplace is comprised of this software configuration management, IT project and portfolio management, and automated software quality markets. In aggregate, IDC estimated these markets would reach $5.2 billion in 2012. Though these markets have been addressed by solutions supporting waterfall and other legacy methods of software development, we think that a transition to alternatives behind software development methodologies like Agile is ongoing. Our cloud-based platform of management alternatives is designed to address these markets and facilitate the adoption of Agile practices by businesses.

 

Furthermore, cloud-based alternatives have a small, but fast growing share of the total application development and installation market, which includes Agile management alternatives.

 

Organizations that develop business applications and software-related products face a range of business challenges. These are usually directly attributable to legacy software development methods. These challenges include:

 

  • Shortening time-to-market and increasing customer expectations. Competition for customers’ attention continues to intensify and, as a result, the importance of being first to market has significantly improved. With the proliferation of always-connected clients and mobile devices, Additionally, product reviews may be continuous and instantaneous. It becomes paramount that characteristics a product’s quality and consumer experience match or exceed customer expectations at launch, as poor client experiences can be readily shared. Customers’ demand for the speed and quality has set increased focus and pressure on how organizations handle the software development lifecycle.

 

  • Limited transparency into big development projects. Comprehensively monitoring the improvement of multi-team development projects and actively monitoring their priorities are challenges. These challenges are exacerbated when projects are big and teams are globally distributed. For projects with priorities and continuously-evolving demands, the ability to keep visibility into quality and progress is more challenging. Organizations who utilize legacy software management offerings may have separate applications for each role and phase of the development lifecycle. These organizations struggle with , out-of-date status info that is siloed and have limited into the work in advance. The ability to effectively adapt, optimize decisions and allocate resources necessitates a view of their software development process together with all teams.

 

  • For large-scale development projects, feedback and collaboration among developers, industry leaders and clients can be hard to coordinate. Collaboration must be continuous and the software development strategy has to allow for adaptation, since the comprehension of customer needs or business needs evolve.

 

  • Difficult transition to alternative development approaches and solutions. Approaches and tools used for managing the software development lifecycle frequently reflect. Because of this, there is a resistance to change, even if change can be demonstrated to boost time-to-market, productivity or software quality. Generally, legacy software management tools do not support the cycles utilised in Agile development. These applications are non-intuitive usually stiff, costly and, requiring implementations, increasing the challenge to some development business or attempting adjustments to its own processes.

 

  • Inflexible offerings. Conventional offerings for and approaches to managing the software development lifecycle can be hard to use or may lack the flexibility required to accommodate changing or varying goals and organizational needs. In addition to this downside, legacy offerings might require substantial resources and time to execute and can often be expensive. Further, after these offerings have been installed, updating, extending or adding new performance often necessitates bespoke development efforts which are time consuming and costly.

A brief guide to cryptocurrency exchanges

With a rapidly growing interest among technologist as well as trader towards cryptocurrencies, we have been writing a series of posts about them. In this post we will be covering cryptocurrency exchanges and point out their characteristics, and hopefully at the end of this post you may get an idea on which crypotocurrency exchange to do your trades.

Generally there are many doubts and question marks around how reliable cryptocurrency exchanges are. There has been a lot of rumors and news also around governments getting involved and closing down cryptocurrency exchanges, we heard that in South Korea  the governments is going to raid the cryptocurrency exchanges operating in the country and shut them down. If you are curious about that story, one of the officials from the government called that an “unrealistic move”. nevertheless in recent times we have heard numerous speculations about cryptocurrency world which never came to life.

The purpose of this post is to assess the most known and used cryptocurrency exchanges. We have chosen arguably the top rated exchanges, basing on fees applied, how safe the exchange is, if liquidity in the exchange is high or not, the possible pairs and currencies to trade with  USD, Euros or crypto with crypto and so on. The list we have gathered is narrowed with qualities indicated above.

Coinbase

Coinbase is one the most known and used exchange for Cryptocurrencies with up to 10 million users.

How to use Sharpe Ratio?

The Sharpe Ratio is well known measure of portfolio performance. It is a ratio which allows to compare various portfolios and allows to measure theirs profitability. The mathematical definition is described as a division between expected rate of return subtracted by risk free rate of return and standard deviation of rates of return [6].

In practice the ratio is calculated annually:

sharpesratio

 

The ratio describes how much excess return you are receiving for the extra volatility that you endure for holding a riskier asset ([1]). In simple words, the higher Sharpe Ratio is, the portfolio is more profitable.

Empirica is offering solutions such as Algorithmic Trading Software used by professional investors and tools for crypto liquidityRobo Advisory softwarecrypto trading bots and trading software development services for companies from capital and cryptocurrency markets.

 

Why is  Shapre ratio so popular?

 

Most traders are still using the Sharpe Ratio because of its simplicity and ease of interpretation. It was proposed by Sharpe in 1966 and became credible to most users due to Nobel Prize in Economics for his works on Capital Asset Pricing Model ([5]).

 

Properties of the Sharpe Ratio

 

With reference to [1], the ratio has several properties. It is immune to manipulation by leverage. It can be interpreted as a T-statistics to test the hypothesis (see [8]) that the return on the portfolio is equal to the risk free rate of return.  The higher ratio is consistent with a higher probability that the portfolio return will exceed the risk- free return. The investor who is using the ratio has a utility (see [7]) whose only arguments are expectation and variance of returns.

 

Forgotten assumptions

 

Unfortunately, most traders forget that the Sharpe Ratio doesn’t apply for every set of data. The main assumption of the ratio is that the distribution of the returns is normal. The financial market should be frictionless (without financial costs) and the risk free rate of return should be constant and identical for lending and borrowing. Also data used for computation should contain initial capital of the portfolio.

Consequences of the ratio

Despite the fact that it is really hard to obtain normality of returns on every possible data, the Sharpe Ratio has other disadvantages which are represented from [1].

The ratio does not quantify the value added and it’s only a ranking criterion. It has hard interpretation when the value is negative. The Sharpe ratio does not make any distinction between upside risk and downside risk.

In case of aggregation of portfolios, the correlation between volatilities is not included in the ratio. It is suitable for investors who invest in only one fund.

It doesn’t refer to a benchmark. The choice of risk free rate is rather important, though the impact is rather week. The result highly depends on the initial capital of the portfolio.

The sampling error of standard deviation is embedded in the values of the ratio. By using standard deviation of returns, the Sharpe measure puts both positive and negative variations from the average on the same level. But most investors are only afraid of negative variations.

As a consequence, the Sharpe Ratio leads to inappropriate results on particular sets of data.

 

When the ratio fails

 

To be aware of how important are the assumptions, consider the following example [*]:

In the case when the expected return is negative, the Sharpe Ratio gives inappropriate answer. The Sharpe Ratio from Instrument A should be greater than the Sharpe Ratio from Instrument B.

INVESTMENT A SHARPE RATIO
TOTAL RETURN -10.00% -1.5
RISK FREE RATE 5.00% NUMERATOR -15.00%
STANDATD DEVIATION 10.00% DENOMINATOR 10.00%
INVESTMENT B SHARPE RATIO
TOTAL RETURN -10.00% -0.92
RISK FREE RATE 5.00% NUMERATOR -15.00%
STANDATD DEVIATION 16.25% DENOMINATOR 16.25%

 

Solution to Negative Returns

 

In the case of negative returns, the Israelsen modification of a Sharpe Ratio gives appropriate results. This ratio could be used as a verifying measure of a standard Sharpe Ratio (the values are meaningless but the order remains accurate).

The Israelsen modification of the Sharpe Ratio from a previous example provides that Instrument A is greater than the Sharpe Ratio from Instrument B.

INVESTMENT A SHARPE RATIO ISRAELSEN
TOTAL RETURN -10.00% -0.015
RISK FREE RATE 5.00% NUMERATOR -15.00%
STANDATD DEVIATION 10.00% DENOMINATOR 10.00%
INVESTMENT B SHARPE RATIO ISRAELSEN
TOTAL RETURN -10.00% -0.024
RISK FREE RATE 5.00% NUMERATOR -15.00%
STANDATD DEVIATION 16.25% DENOMINATOR 16.25%

As a conclusion, in the case when the negative returns occurred, the investor should also check the value of the Israelsen modification before making the decision.

 

Avoiding invalid distribution

 

The most dangerous usage of the ratio is when the distribution of the returns isn’t normal. It seems that the best idea is to check normality of the returns before use of the Sharpe Ratio. There are several statistical test that can validate data’s distribution such us: Sharpiro Wilk, Anderson Darling, Cramer von Misses, Dagostino Pearson, Jarque Berra, Kolmogorov Smirnov, Kolmogorov Lilliefors, Shapiro Francia (see [9]).

 

Generalizing Sharpe Ratio

 

On the other hand there are different extensions of the Sharpe Ratio, which gives more accurate results by extending different assumptions. There are plenty of them described in [1], but only these which contain skewness and kurtosis will be presented.

Skewness describes asymmetry of the probability distribution. If there are more extreme returns extending to the right tail of a distribution it is said to be positively skewed and if they are more returns extending to the left it is said to be negatively skewed [2].

Kurtosis provides additional information about the shape of a return distribution. Formally it measures the weight of returns in the tails of the distribution relative to standard deviation but is more often associated as a measure of flatness or peakedness of the return distribution [2].

Skewness and Kustosis are normalized forms of 3rd and 4th central moments respectively (see [10]). Its combination with the Sharpe Ratio allows to approximate the ratio when the distribution is not normal. This method leads to the proposition from [4], where skewness divided by kurtosis is added to the Sharpe Ratio which results a new performance measure.

In the case when the owner of the portfolio has different preference (different utility – see [7]), there are other ratios to measure the performance. The Adjusted for Skewness Sharpe Ratios, gives the opportunity to measure the performance using hyperbolic absolute risk aversion (HARA), constant relative risk aversion (CARA) or constant absolute risk aversion (CRRA). More details can be found in [3].

 

Conclusion

 

The Sharpe Ratio is a standard measure for portfolio performance. Due to simplicity and ease of interpretation, it is one of the most popular indexes. Unfortunately, most users forget the assumptions what results inappropriate outcome. They should consider checking the distribution of the returns or validating the results with other performance measures before making a decision on the market.

Who is moving FinTech forward in continental Europe? Thoughts after FinTech Forum on Tour.

By Michal Rozanski, CEO at Empirica.

In the very centre of Canary Wharf, London’s financial district, in a brand new EY building, a very interesting FinTech conference took place – FinTech Forum on Tour. The invitation-only conference targeted the most interesting startups from the investment area (InvestTech) from mainland Europe. The event had representative stakeholders from the entire financial ecosystem. As Efi Pylarinou noted – the regulator, the incumbents, the insurgents, and investors, were all represented.

 

Empirica was invited to present its flagship product – Algorithmic Trading Platform, which is a tool professional investors use for building, testing and executing of algorithmic strategies. However, it was amazing to see what is happening in other areas of the investment industry. There were a lot of interesting presentations of companies transforming the FinTech industry in the areas of asset and wealth management, social trading and analytics.

 

The conference was opened with a keynote speech by Anna Wallace from FCA. Anna talked about the mission of FCA’s Innovation Hub; that is to promote innovation and competition in the financial technology field and to ensure that rules and regulations are respected. Whilst listening to Anna it became clear to me what the real advantage of London holds in the race to become the global FinTech capital – London has Wall Street, Silicon Valley and the Government in one place – and what’s most important, they cooperate trying to push things forward in one direction.

 

FinTech Forum on Tour

 

Robo-advisory

A short look at the companies presenting themselves at the event leads to the conclusion that the hottest sector of FinTech right now is robo-advisory. It’s so hot, that one of the panellists noted it’s getting harder and harder to differentiate for robo-advisory startups. On FinTech on Tour this sector was represented by AdviseOnly from Italy, In2experience,  Niiio, Vaamo and Fincite – all from Germany. Ralf Heim from Fincite presented an interesting toolkit ‘algo as a service’ and white label robo-advisory solutions. Marko Modsching from niiio revealed the motivation of retail customers, that “they do not want to be rich, they do not want to be poor”. Scalable Capital stressed the role of risk management in its offering of robo advisory services.

The social or sentiment analysis area, keeps growing and gains traction. Every day there’s more data and more trust in the results of backtesting as that data builds up over the years. The social media space is gaining ground. Investment funds as well as FinTech startups are finding new ways to use sentiment data for trading. And, it’s inseparably related with the analysis of huge amounts of data, so technically the systems behind it? are not trivial.

Anders Bally gave an interesting presentation about how to deal with sentiment data and showed  how his company Sentifi is identifying and ranking financial market influencers in social channels, and what they discuss.

Sentitrade showed its sentiment engine for opinion mining that is using proprietary sentiment indicator and trend reversal signals. Sentitrade is concentrated on German-speaking markets.

 

Asset management

From the area of asset management an interesting pitch was given by Cashboard, offering alternative asset classes and preparing now for a  huge TV marketing campaign . StockPluse showed how to combine information derived from social networks and base investment decisions on the overall sentiment. United Signals allows for social investing by making it possible to trade by copying transactions of chosen trading gurus with a proven track record, all in an automated way. And, finally BondIT, an Israeli company, presented tools for fixed income portfolio construction, optimization and rebalancing with use of algorithms.

 

Bitcoin and Blockchain

An interesting remark was given   by one of the panelist: ‘we have nearly scratched the surface for what blockchain technology can be applied to in financial industry’. Looking at the latest news reports that are saying that big financial institutions are heavily investing in blockchain startups and their own research in this field, there is definitely something in it.

A company from this sector of FinTech – Crypto Facilities, represented by its CEO Timo Schaefer, showed  the functionalities of its bitcoin derivatives trading platform.

 

Other fields

Hervé Bonazzi, CEO of Scaled Risk, presented its technologically advanced Big Data platform for financial institutions for risk management, compliance, analytics and fraud detection. Using Hadoop under the hood and low latency processing. Ambitious as it sounds.

Analysis of financial data for company  valuations, Valutico presented a tool that’s using big data, AI and swarm intelligence. Dorothee Fuhrmann from Prophis Technologies (UK) presented a generic tool for financial institutions to derive value and insights from data, interestingly describing indirect exposures and a hidden transmission mechanism.

Stephen Dubois showed  what Xignite (US) has to offer to financial institutions and other FinTech startups in the area of real-time and historical data that is stored in the cloud and accessible by proprietary API.

 Qumram, in an energetic presentation delivered by Mathias Wegmueller, described technology for recording online sessions on web, mobile and social channels, allowing for the analysis of user behaviour and strengthening internal security policy.

 

Conclusion

London is the place to be for FinTech startups. No city in Europe gives such possibilities. Tax deductions for investors. Direct help from the UK regulator FCA. Great choice of incubators and bootcamps for startups. No place gives such a kick. Maybe Silicon Valley is the best place for finding investor for a startup, maybe the Wall Street is the centre of the financial world, but London is the place that combines both the tech and the finance. It has a real chance of becoming the FinTech capital of the world.

 

About organizators

The people responsible for creating both a great and professional atmosphere at the event were Samarth Shekhar and Michael Mellinghoff. Michael was a great mentor of mine who transformed my pitch from a long and quite boring list of functionalities of our product to something that was bearable for the audience. Michael let me thank you once more for the time and energy you have devoted to Empirica’s pitch!

 

And because the FinTech scene in our region is not well organized yet, I sincerely advise all FinTech startups from Central and Eastern Europe to attend cyclic events of FinTech Forum in Frankfurt organized by Techfluence professionals!

Empirica has been nominated for Best Fintech Startup at CESA 2015

 

Empirica has been nominated for the Best Fintech Startup in Poland at the CESA festival. CESA (Central European Startup Award) is the biggest no-pitch, no-conference start-up festival in the Central-Eastern European region. The festival brings together nearly 4.000 start-ups from 10 countries and it will be held in Vienna this year.

We are in good company, as other companies nominated in FinTech category are:

  • Zencard
  • Billon
  • WealthArc
  • our friends from FriendlyScore

The Central European Startup Awards is a series of events in the CEE countries, that aims to recognize and celebrate the entrepreneurial spirit and startup ecosystems of the region. This year eight categories will be awarded in:

  • Startup Of The Year
  • Best Investor
  • Best FinTech startup
  • Best Cloud/Data Application
  • Best User Experience
  • Best Social Impact Startup
  • Most Influential Woman
  • Best Coworking Space

 

CESA regognized FinTech as separate category this year reflecting that financial technologies are now the fastest growing technology sector worldwide. Incumbents in the financial industry – big banks and other financial institutions – are witnessing the emergence of new players that are profoundly changing the way individuals and business conduct their financial operations. Global investment in financial-technology (fintech) ventures tripled from $4.05 billion in 2013 to $12.2 billion in 2014, with Europe being the fastest growing region in the world, according to a report by Accenture.  Last year, fintech investment increased at more than three times the rate of overall venture capital investment. While it remains to be seen whether the burgeoning fintech industry will actually pose a threat to established institutions, it is clear that the sector is rapidly growing and many of these entrants are here to stay. Investors in the nascent sector are taking notice, profitable exits are on the horizon, and big banks are investing in new technologies to strengthen their competitive positions.
