Is Blockchain All Fuss About Nothing?
2018-09-10 11:08:22

Is Blockchain All Fuss About Nothing?

Unless you’ve been stranded on a desert island for the past couple of years, you will have heard about BITCOIN. And probably, that Bitcoin is built on BLOCKCHAIN. Which is true. However, contrary to what many people assume: Bitcoin is not identical to Blockchain. Bitcoin is digital money, a virtual currency that was the first successful Blockchain product, whereas Blockchain is the technology that enables cryptocurrency like Bitcoin. In this article, we will be traversing in length the ins and outs of this novel technology.

What is Blockchain?

In simple terms, Blockchain is a digital record of data (information and transactions). The data is grouped together and organized in blocks. The blocks are then linked to one another and secured using cryptography. So… it’s a chain of blocks that builds the Blockchain.

The interesting bit about this is that the digital database is replicated on multiple computers scattered around the world. They act as decentralized ledgers. Hence the name Distributed Ledger Technology.

How Blockchain works

As each ledger on each computer contains a record of all transactions, arranged in sequential “blocks” and as the ledger is public, or “distributed”, it cannot be tampered with by a single user. An altered version would quickly be rejected by other users.

Also, as it is decentralized, it is not controlled by any single entity. Rather, decisions are reached via a consensus algorithm. Again, no single user can change the data all by themselves.

Some will also say it is un-hackable. But that takes it a step too far. It could be hacked — but that would be a hugely expensive and time-consuming task.

What it is, though, is immutable because once new data is entered, it cannot be changed, deleted or altered. If a transaction occurs, a new block is added. The old blocks remain as they are.

Before new information is added to the Blockchain, the different computers (nodes) running the Blockchain software, have to first verify that the information given is correct. Once verified, the new information is added to a block. More data, more blocks.

As to the verification process: there are different ways of verifying the data. We will look at these processes in another blog post.

What it can be used for

Bitcoin and other cryptocurrencies happen to be the most popular use case of Blockchain. But of recent, there has been a surge in projects that centre around use cases in nonfinancial sectors, from shipping and logistics to farming.

Healthcare: A recent study from IBM found that 56% of surveyed healthcare executives had solid plans to implement a commercial Blockchain solution by 2020. To give a concrete example: a 15-year old girl — Ananya Chadha — at the last CryptoChicks Hackathon used Blockchain to track genetics and DNA mutations.

Education: At a recent Blockchain for Kids class, some of the kids suggested that Blockchain can be used to track payment of school fees. Some universities are exploring the use of Blockchain applications to record degree certificates which can be tokenized and verified by anyone anywhere.

Government: Whether for things like voting or identity management, tokenised can be used to track and verify votes cast and people’s ID.

Industrial and supply chain: Think verification of genuine products, then you have a use case of tokenised in the industrial sector. Granted, this will involve collaboration with IoT, RFIDs tags and other technologies. But that, in turn, is not a problem for a series of smart contracts working together.

Recreation and Sports: This is where we come in and we will therefore explore this part in more detail. Sports Ledger (SPSL) will redefine the way we understand and interact with every part of every sport. Sports Ledger is a cutting-edge tokenised platform that will achieve its goal through all-inclusive sports- related services and products, relevant to a vast number of fans, athletes, trainers, clubs and the corporate world. Regardless of their location on Earth, participants will be able to access the SPSL ecosystem with just a smart device.

What makes Sports Ledger unique?

Imagine social sports communities, where fans can engage with fans and clubs directly and in an uncomplicated manner. Imagine a platform that will be driven by new technologies, including tokenised, AI, smart contracts and biometrics … and through this unlock new possibilities for sporting interactions. A platform that will deliver value to its users through innovative analytics and through a reward system incentivising those who actively contribute to the ecosystem.

At the same time, deeply embedded in the five core layers of the Sports Ledger platform is the aspiration to bring about positive social change, both within the sporting world and the global community at large.

Sports Ledger — The Future of Sports

Risks and opportunities for today’s business

Undoubtedly, Blockchain Ttechnology is going to have a significant impact on the world as we know it. Some liken Blockchain to an internet of value — whereas the internet we are all familiar with is the internet of information.

Businesses with a desire to stay ahead are all taking steps to explore ways to integrate blockchain into their activities as blockchain holds almost unlimited opportunities for today’s businesses, from storing transparent, decentralized records and through this empower people to transfer value and ownership in a totally new and cost-efficient way, to utilizing the platform for crowdfunding through an ICO. Finally, Blockchain will also create new opportunities for doing good, for bringing about social change and progress that will impact billions of people.

This doesn’t mean that we will not encounter speed bumps on this journey. Always likened to the era of the early days of internet, Blockchain as a new technology has a long way to go. But as things get refined and mainstream adoption accelerates, its potential will exceed our expectations by far. We at Sports Ledger are deeply convinced of this and are working hard to making a brighter, fairer and more equitable future a reality.

Do we have the Optimal Process for Premier League Transfers?
2018-08-11 14:27:57

Do we have the Optimal Process for Premier League Transfers?

With deadlines looming on the closer of the Premier League transfer window, many have been left speculating on which clubs will be signing who this summer.

Copyright © Getty Images | Manchester United

The domestic transfer window officially opened on May 17, a few days after the final games of the league season concluded and the deadline is set for August.

Premier League clubs voted to end the summer 2018 transfer window at 17:00 BST on Thursday, August 9. Three weeks sooner than previous years under the new FA rules.

This means that all English clubs must complete any domestic transfer deals or purchases of players before the Premier League season starts on Saturday, August 11. This is to avoid club disruptions, performance and results due to players moving clubs after the season has already started.

Although buying activity will cease, English clubs will still be able to sell players overseas to Spanish, German, Italian and French clubs, with FIFA’s official deadlines remaining set for Friday, August 31.

Record-breaking transfers in 2018

The 2018 transfer window once again saw record-breaking transfers and historical moments, year on year breaking previous statistics.

Leading the way; Barcelona with a record-breaking £111m sales earning from summer transfers.

Juventus made headlines earlier this year with announcement of securing Cristiano Ronaldo from Real Madrid for £89m, allowing him to fulfil a childhood dream.

Chelsea have broken the world record transfer fee for the most expensive goalkeeper Kepa Arrizabalaga at a hefty price of £71.6m.

Alternatively, Tottenham have become the first team in Premier League history not to make a single summer signing since the transfer window’s inception in 2003. This could prove a mistake or a moment of genius.

True price discovery of players

With every transfer, clubs plan vigorously to justify their new purchases, with emphasis on improving scores, results and trumping league tables. However, the resources they use are still relatively limited in their capacity — even though the use of IoT has changed the game already.

A few years ago, a football club might have a handful of GPS units in use to analyse players’ movements. Today this number easily can be over 100. Clubs are becoming more proactive in their use of data and their efforts to be more predictive.

Clearly, player data is essential for clubs and athletes alike. The question is: are they getting the most out of the data?

We don’t think so. There is an ocean of numbers out there. But available data is not utilized to its maximum extent to create information that is truly applicable and easy to use.

In the business world, rapid technological advances in digitization, AI and machine learning are reshaping the landscape and supercharging performance. And as technology itself continues to evolve, it will enable the emergence of new business innovations and new forms of competition.

We are convinced, that the same applies to the world of sports: rapid technological advances will reshape the sporting landscape and revolutionise how we engage with sports. And as the technology itself continues to evolve, it will enable the emergence of new forms of competition — and it will enable the creation of new business innovations, such as Sports Ledger.

Utilizing IoT, AI and machine learning in a way we’ve never seen before, the Sports Ledger platform will use data as digital fuel that powers its services and offerings.

The cutting-edge Sports Ledger platform will aggregate high-quality data in order to provide users with intuitive visualisations, predictive analytics and insights into athletes’ biometrics.

Sports Ledger is built on the core principle that access to sports data should not be as complicated or inaccessible as it currently is. We want to enrich the experience of sports fans and platform users by enabling them to interact and learn from the platform’s innovative data tools.

By incorporating a variety of data tools, the Sports Ledger platform will offer a range of benefits to a variety of stakeholder groups from all around the world, including academic researchers, sporting institutions, professional athletes, clubs, coaches, managers, scouts, agents and, most importantly, sports fans.

Users will only need a smart device (laptop or phone) and the platform’s key — SPSL tokens — to form part of this data revolution. Thereafter, these users will gain access to a cutting-edge platform that relies on Artificial Intelligence, Blockchain and Smart Contracts to secure data, offer new insights and reward meaningful contributions. As the first-movers in this space, we expect the number of platform users to grow at a fast rate thanks to the network effect.

The current data-sharing ecosystems within the world of sports are severely outdated and fragmented. Against this backdrop, Sports Ledger will be effective in overcoming legacy burdens and cumbersome procedures that are currently used to access sports data. This paradigmatic shift in the aggregation, processing and analysis of data will prevent decisions from being based on low-quality data, reduce information costs and resolve disparities in the data.

Article by: @jackpittbrooke

The Wales and West Brom striker is an expert in blockchain technology and crypto-currencies, and intends to use his knowledge on a new application out next year

Sports Ledger at Blockchain Summit London 2018

Thomas Robson-Kanu, known to the football world as ‘Hal’, is explaining exactly what ‘blockchain’ is. With patience and precision, he moves through the basic definitions towards more advanced concepts. What is crypto-currency? What is a smart contract? What is network effect? What distinguishes BitCoin from LiteCoin, or DigiByte from Ethereum?

But by night, or rather in the afternoons, Robson-Kanu is a blockchain entrepreneur. When West Brom training finishes at lunch-time he drives down to London, sees his family and then goes to his office in Chiswick. Where he works until 9pm on ‘Sports Ledger’, the blockchain-based sport data-sharing platform his team have been developing for the last two years. “Lots of athletes have other interests. Some of my team-mates finish playing FIFA at 12.30 at night.”

Sports Ledger at Blockchain Summit London 2018

So two years ago, Robson-Kanu, his brother David, childhood friend and developer Bozidar Ijacic and German blockchain expert Fabian Kippenberg decided to launch a blockchain-based sports application. Early last year they came up with the name ‘Sports Ledger’, and the application will be gradually rolled out from the second quarter of 2019 onwards.

Eventually Robson-Kanu wants Sports Ledger to improve connections between clubs and fans and to even hold biometric data from athletes’ training sessions from all over the world, information that has never been public before. “Most blockchain enthusiasts have a bias for transparency,” he explains. “They feel that everything should be open and available for access.”

Sports Ledger Social Impact

Sports Ledger Social Impact

More info at:

Deeply embedded in the five core layers of the Sports Ledger platform is the aspiration to bring about positive social change, both within the sporting world and the global community at large.

The elements driving positive change have been incorporated into the foundations of Sports Ledger from the outset. The platform will not only deliver immense value to individuals around the world who have an affiliation to sport but bring further tangible value to the world from which it springs.

In addition, the Sports Ledger platform will be used to finance the Sports Ledger Foundation, aimed exclusively at effecting positive global change by leveraging for good the technologies Sports Ledger is using.

Delivering Social Impact Through the Sports Ledger Foundation

The Sports Ledger Foundation is an initiative aimed exclusively on effecting positive global change, leveraging technologies for good, and setting a benchmark for building and maintaining a transparent Corporate Responsibility program.

Focusing on improving opportunities for underprivileged populations, facilitating health research and care, and supporting initiatives dedicated to solving hunger, famine and starvation, the Foundation will be initiated by Sports Ledger through an annual redistribution of SPSL tokens. To increase the effectiveness of the Foundation‘s work, we plan to build relationships with non-profit organisations that bring about real global change and where the innovation, transparency and value that the Sports Ledger platform brings to the global sports world represents a fundamental support factor. The first partnership the Sports Ledger Foundation has agreed to engage in is with the initiative of UInspire. We will actively assist in building its global network for positive social change. More to follow…

Delivering Social Impact Through the Sports Ledger Platform

Giving Back Fundamental Control to the Users

The core services of the Sports Ledger platform will allow users to create enriched digital identities within a decentralised architecture. Users will be in complete control of the access they grant others to their profile. They will also control the type of information (such as advertisements) which they will receive, with complete ownership of their own profile of data. Each individual’s digital identity will be a private yet enriched data profile, encompassing behavioural analytics of the user created while using the services which the Sports Ledger platform delivers.

Until recently, society has accepted the centralised nature in which personal data has been owned and subsequently monetised by large corporations. By offering ‘free’ services embedded within digitally interactive platforms they acquired personal information including personalised digital behavioural patterns which are sold together

with the right to communicate to these profiles. This value is epitomised in the billion-dollar revenues of mainstream social content sharing platforms, which offer their users a ‘free’ service but in which the user itself is effectively the product they sell. Captured within these centralised structures a user will fundamentally receive little to no reward for providing this rich source of data.

However, the true value of access to an individual’s data through their digital data profile is finally becoming recognised and acknowledged — even though solutions for alternative structures yet remain sparse.

By delivering an architecture which offers value through a user-inclusive, socially interactive platform and by harnessing the value of its core services tailored to the world of sports within a decentralised structure, Sports Ledger is able to create an ecosystem in which every user can now be rewarded directly for creating enriched digital identities - simply through participation — and providing access to their digital profile.

In contrast to many other platforms, the users of Sports Ledger will be able to tailor the messaging in the form of advertisements received from third party platform participants to their personal profile and be rewarded in SPSL tokens for allowing and viewing any tailored information they receive. The creation of this ecosystem has the potential to disintermediate the global sporting advertisement industry, currently worth $62 billion and create reward systems which bring value back to each user in the form of SPSL tokens, based on the marketing intelligence they create.

Sports Ledger at Blockchain Summit London 2018

Providing Sports Stars with an Opportunity to Give Back

By giving professional athletes the possibility of opening up their daily biometric sporting data passport to Sports Ledgers global community of users, professional athletes and sports stars around the world will create a new token economy — where there will be an exchange of SPSL tokens for in-depth access to their own sporting digital data passport within their own sporting profile.

Fans, clubs, organisations and interested parties desperate to view their outputs on a day-to-day basis, will be able to use SPSL tokens in subscription models to follow and track their favourite players in all sports from around the world, creating a new level of fan-and-player engagement, and creating a new market for data from the sports professionals’ perspective. This subscription service will offer users and fans of the Sports Ledger platform a never before seen insight into the world of sports, through the daily sporting experiential outputs of their favourite elite athletes.

Part of the incentive for athletes and clubs to use the Sports Ledger platform and incorporate the Sports Ledger wearable technology into their day-to-day routine will be from the evident benefit of having a platform which will deliver a level of analysis on their sporting data currently unattainable, from tracking tools to performance metrics tailored to the athlete, viewable by the player and club in real time. But they will also benefit by creating new reward streams for the club, the player, and most significantly collective charitable initiatives.

When platform participants (users) use their SPSL tokens to view the athlete’s day-to-day passport output of digital data, rewards will be distributed to the player, to the club and also to their charitable organisation choice (or, if preferred, to the Sports Ledger Foundation).

This creates a win-win-win system which:

Incentivises the player to create, record and share the data (which is usually already being collected, albeit in centralised, legacy systems).

Incentivises the club to facilitate a greater bond between their players and their global user fan base with increased engagement through ground-breaking services on top of additional rewards through co-operation.

Incentivises the fans to participate in an initiative which simply through participation gives back to charitable local and global communities.

Sports Ledger at Blockchain Summit London 2018

Providing Wearable Tech to Underprivileged Communities

Through technological innovation, Sports Ledger will create an initiative for young athletes around the world to better understand what is required to achieve their ambitions of becoming a professional athlete — providing opportunity and an avenue through which to achieve their sporting dreams.

Budding sports stars from underprivileged backgrounds and locations from around the world can request and receive professional-grade biometric wearable technology from the Sports Ledger Foundation, combined with a unique profile integrated within the Sports Ledger application.

Through wearing this technology over a sustained period of time and simply having access to a GPS signal and a basic smart device, these young athletes will be able to record their daily sporting data outputs and performance to an unprecedented granular level of detail. This technology, which would be inaccessible for such underprivileged young athletes by any other means, will allow each individual to create a complete personal profile of their overall sporting ability.

In addition, the Sports Ledger Foundation will provide to each individual exclusive access to available complete performance passports of current top-level sporting athletes (the professionals they aspire to replicate). The Sports Ledger platform being accessible to these young potential superstars from around the world will provide each one of them a unique barometer within a ground-breaking platform to benchmark their own performance against — allowing them to understand, visually interpret and physically feel what it really takes to succeed.

Having this technology in combination with a platform where they can record and interpret their own sporting ability creates further opportunity for their own performance passport to be noticed by interested scouts, clubs and leagues around the world — facilitating a route towards a career as a professional athlete which would otherwise be completely unattainable. This will have a beneficial knock-on effect on their communities and encourage the nurturing of sporting talent as an aspirational goal for wellness and success.

Sports Ledger at Blockchain Summit London 2018

Tokenising Corporate Ticketing for Community Benefit

Sports Ledger aims to initially tokenise corporate match day tickets for teams and clubs all over the globe, offering a platform which will allow instant and seamless communication between the club and its fans — offering the opportunity of instantaneous reward.

Via tokenising a portion of match day club tickets on the Sports Ledger platform, Sports Ledger will bring fans and clubs closer together and create greater connectivity between them, enabling clubs to understand their fans in much greater detail based on their rich digital identities and behavioural analytics. It also provides clubs with a seamless platform for distributing rewards as well as receiving instantaneous feedback from supporters — such as in-game experiences (for instance by voting on the man-of the match through the unique ID of the tickets which were purchased through the platform).

An ecosystem with this level of interconnectivity around the digital distribution of tickets also allows for a greater level of flexibility for those who receive them. It is a fact that a large portion of corporate seats for live sporting events, particularly at clubs, stand empty. Sports Ledger will incentivise clubs and corporates to redistribute empty seats at live games in a fast and frictionless manner via the technology and capability of the Sports Ledger platform, enabling local communities — including fans from underprivileged families, trustworthy organisations and positive initiatives — to be rewarded with a seat at a live event through this initiative. An opportunity for a young child, family or social worker to experience the beauty of live sport from a perspective which, for the majority of them, would be unattainable — and giving players and clubs the full crowds they deserve for their fixtures.

Sports Ledger SPSL Token Benefits
2018-06-28 23:14:23

Sports Ledger SPSL Token Benefits

The SPSL Token: this is an ERC20 token that is limited in supply. Once our initial token offering (ITO) is complete, no more SPSL tokens will be issued. SPSL is a utility token that provides users with the right to participate in our platform and consume its content. This is a product of its utility (how useful is it) and velocity (how quickly it changes hands).

Sports Ledger at Blockchain Summit London 2018

Initial Token Offering Smart Contract

We will be posting the source code for our ITO smart contract on Github and Etherscan. This will be subject to an audit to ensure that it is free of known bugs and vulnerabilities at the time of launch – the security of investors is our priority. We aim to work with reputable exchanges after launch to create a stable secondary market where early adopters can opt to transfer their tokens after a successful launch and new users can gain access to the platform.

Blockchain, Smart Contracts, AI & IPFS
2018-06-28 23:07:03

Blockchain, Smart Contracts, AI & IPFS

In this article, we provide an accessible introduction to the suite of technologies that we reference throughout the paper. In combination, these technologies will provide the backbone for our platform and enable us to generate value in innovative ways for sports professionals, fans and clubs alike.

Blockchain technology first came to prominence as the technology underpinning the Bitcoin network, which was introduced by Satoshi Nakamoto (pseudonym) in 2008. Many have compared this technology to the internet, as it is building new digital roads to interconnect people, computers and data. The technology is evolving at a very fast rate and new features are being tested on a regular basis, which makes it hard to isolate a set of defining attributes.

As a result, it is helpful to distinguish between the broad and narrow uses of the term. In broad terms, blockchain is used to describe the suite of technologies that allow (i) computers in a peer-to-peer network (ii) to reach agreement over (iii) shared data. Though the word blockchain, in its broad sense, is often used to describe these 3 elements, the term distributed ledger technology (DLT) is more accurate in this context. This distinction is relevant because there is a narrower (and more natural) meaning of the word blockchain.

In the more narrow sense, blockchain refers to a specific data structure that a network’s shared data usually (though not necessarily) will adopt. A data structure is a way of organising and storing data so that it can be used efficiently. In a blockchain data structure, the data in the ledger is organised into a series of interlinking blocks. These blocks are indexed in a similar way to page numbers. Each block contains a timestamp and a link to the previous block, with the result that a chain of blocks is created.

Sports Ledger at Blockchain Summit London 2018

The blockchain data structure makes it simple for computers to verify the consistency of a long and growing number of ledger entries. Blocks are signed with a digital fingerprint, known as a hash value (or ”hash”), which takes the form of a string of characters that is fixed in length. Each block also stores the hash of the previous block in the chain.

Hashes are useful because they are data-specific. If an alteration is made to the data within a block, the block’s hash will change and the chain will break. Should a person attempt to distribute a corrupt ledger, for instance by replacing one of the addresses in a previous block for their own, other nodes will identify the misalignment and reject that version of the ledger. Therefore, this simple tool enables nodes in the network to agree on which entries should be rejected without having to rely on a central authority. This can lead to savings in costs and time, while providing access to a global payments infrastructure.

The launch of the Ethereum network in 2015 constitutes an important milestone in the realm of blockchain. Ethereum is a general purpose platform that enables users to create their own DLT-based applications and cryptocurrencies. Ethereum also popularised the concept of a ”smart contract”, though this can be traced back to the work of Nick Szabo in the 1990s.

Smart contracts are software agents that utilise DLT to govern the relationship between two or more transacting parties. In particular, DLT allows for the transfer of digital assets and information in accordance with the parameters (or rules) embedded in the smart contract. Smart contracts can therefore be used to automate the execution of parties’ obligations, creating a mechanism that is able to secure performance or enforcement in accordance with the encoded set of rules. Another important characteristic that smart contracts derive from DLT is their tamper resistance. Since nodes in the network will receive a copy of the smart contract’s contents once deployed, the contract can be protected from malicious or unauthorised alterations. Only those parties who are granted rights by the smart contract will be able to trigger an execution of its code. Further, parties can track a smart contract’s state in order to verify that all transfers have been correctly executed and observe the current status of their relationship.

In the context of DLT networks, smart contracts allow parties to form novel types of virtual relationships, ranging from simple consumer dealings to distributed autonomous organisations (DAOs). In addition, smart contracts have enabled a new form of crowdfunding to emerge, commonly referred to as an ”initial coin offering” (ICO) or ”token sale”. In 2017 alone, over $3.5 billion was raised via ICOs, surpassing venture capital as the primary form of financing for DLT-based projects.

”In the long term, smart contracts are likely to play a pivotal role in reducing the legal and economic frictions that erode value in conventional contracting processes.”

The cost of storing data on a DLT network is prohibitive expensive, as every full node in the network has to download a copy of the data submitted. For instance, the cost of storing 1GB on the Ethereum blockchain is currently around $6,400,000. Similarly, the maximum size of a block in the Bitcoin network is 1MB — anything above this will simply not fit in. The reason why transactional data can be stored in the blockchain is because it takes up a negligible amount of storage space. In contrast, documents, media and other forms of content need to be stored off-chain by necessity.

The InterPlanetary File System is designed to address this specific challenge, as it comprises a P2P file storage system. When a user wishes to store a file in the network, this file is encrypted and split into small chunks. In turn, each of these chunks is allocated to a different node in the network. This system ensures that no single node can control or access the full dataset, allowing the integrity of the data to be preserved. At the same time, the destination of these data chunks will be indexed to allow the rightful owner to request access from the relevant nodes. As with DLT networks, IPFS has no single point-of-failure and, unlike the https protocol, prevents distributed denial of service (DDoS) attacks.

Some of the main competitors of IPFS are 0Chain, EOS Storage and Swarm. These competitors are still in the process of being developed, so it is too soon to conduct a full review of the comparative advantages of each system. Swarm for instance could be a better alternative to IPFS in the long-term, as it does not require nodes to stay online (unlike IPFS). In view of the rapid change that is taking place in this space, we have placed an emphasis on building a platform that is modular and technology-agnostic. To allow our platform to switch from IPFS to alternative storage systems as required, we will implement a storage abstraction to allows these alternative systems to be plugged in when deemed to be in the best interests of our users.

Artificial intelligence (AI) is the science of creating intelligent machines that use computational methods to achieve a prescribed set of goals. Currently, these goals usually involve taking decisions or making calculations in a similar fashion to human beings. However, AI is also capable of outperforming humans by carrying out tasks in a more efficient and accurate manner. The rapid growth in the amount of data that is available (big data), and the increase in computing power predicted by Moore’s Law, have allowed the field of AI to grow at an unprecedented rate in recent years.

In turn, machine learning (ML) is a subset of AI in which a set of training data is fed to a computer, helping it to develop an algorithm that maps the inputted set of data to a specific output. The training data may be labelled (supervised learning) or unlabelled (unsupervised learning). In contrast to traditional programming, the algorithm is created by the computer (as opposed to a human). Importantly, the accuracy of this algorithm will increase over time as the machine processes new data.

Machine learning allows us to discover patterns in data that can be used to make accurate predictions about future outcomes. As such, this powerful technology can be used to generate predictive analytics that are based on historical data. For instance, machine learning could enable fans to obtain an accurate projection of the result for a match. In addition, it could also warn users of which players are most likely to get injured or receive a red card. When combined with data visualisation tools, predictive analytics can enrich the user experience and allow fans to discover a side of sports that they had not yet capitalised on.

CORE V: Incorporating Biometric Data into the Platform

Industry Challenge

”It won‘t be long until they see players wearing devices during games. The key issue then will be who has access to the data and when.”

− Brian Kopp, Vice President of STATS, the world‘s leading sports technology, data and content company.

Within the professional sporting world there is an unbridgeable gap between the verifiability of sports professionals daily data outputs and the understanding, use, and interaction of this data with clubs, the professionals themselves and the sporting world of fans.

Sports Ledger has been and is continuously analysing the wearable technology sector to recognise and strategically implement these technologies by identifying;

Why it has and is progressing at a rapid pace?

Flaws within the technology and data extraction.

Who owns the data?

The huge growth predicted within the upcoming years.

Allowing sporting athletes to control and monetise from their training and in future real-time live match data.

Implementing these technologies through athletes within the Sports Ledger network.

Sports Ledger at Blockchain Summit London 2018

The current use of biometric real-time data monitoring and extraction is growing and has become a reality with numerous companies implementing Nano and Biometric wearable tech systems within professional sporting clubs on all sports professionals on a daily basis, however the use of this rich level of sporting data has become stagnant with a lack of algorithms placed on this data to understand and comprehend it better, combined with the fact that the data collected is used within centralised and siloed systems, with an inability for an option to share this data to an avid, receptive sporting global audience.

For athletes globally, innovations in how this data is collected and presented could not come sooner, gaining a golden understanding of what they are actually doing, how they are truly performing, and the use of this as a barometer for improvement or decline. Once delivered, ultimately becoming a competitive edge which they are going to take.

Within all Sports, non-impact related injuries are ever-present. The stem of fatigue and decline in performance, through overtraining and an inability to monitor at a holistic level the granular data generated by sporting professionals on a daily basis, is prevalent within the professional sporting industry. Resulting in a repetitive nature for points of failure for sporting individuals and sporting clubs through inconsistency and unreliability, to the dismay of every interested party in sport, whether it be the sporting professional themselves, or whom they play for, the fans.

The current use of real-time data monitoring and extraction is now a growing reality within all major sports, with companies such as Catapult and Adidas already providing Nano and Biometric wearable tech systems. However key questions remain; how can a system process then deliver this data to the individual (sports professional) the creator, providing them with complete ownership rights and control, and how can this data if chosen be delivered as value, via a network increasing interaction, interest and engagement to a global audience?


Sports Ledger is committed to delivering a world where aspiring youngsters and elite sporting professionals develop and continue to thrive through the latest wearable biometric devices. These devices the capacity to accurately monitor a player’s capabilities, measuring their strengths and weaknesses throughout their career to pinpoint specific areas where progress is still to be made.

By using the Sports Ledger platform, athletes will be able to build their own digital passport with personalised statistics and biometric information. In turn, athletes will have complete ownership of the data, allowing them to control which users are allowed to access this information, such as their own club or the broader fan base. Athletes will also be able to directly monetise this data and to ensure that it is stored in a tamper-resistant and secure distributed network.

Sports Ledger at Blockchain Summit London 2018

An innovative scope of which the implementation of these technologies will bring benefit to the managers, coaches, athletes, teams, sporting bodies, institutions and fans within Sports Ledger:

Secure recording of young and senior sporting professionals daily training and future live performances without physical documents, through the modernised transparency of Blockchains and DLT.

Immutable data outputs from wearable devices will deliver (via GUI) visually enhance analytics across private and public peer-to-peer inter-connectivity, allowing for greater scope into optimising sporting professionals performance and interaction with it.

The capacity for wearable technology to feed live data streams and comparisons back to the coaches and medical staff, enabling early detection of an injury and hence training adjusted accordingly.

Data extracted and provided by the wearable devices represent a continual health profile of the athlete, point of reference for the well-being of the individual.

Delivering a benchmark for athletes to monitor themselves, if subscribed to other professionals Blockchains, a benchmark for themselves against a competitor to identify areas for improvement.

CORE V encompasses a platform that encourages the global integration of engagement and user/viewer interaction through the perspective of the professional athlete fitted with Nano, Biometric wearable technology.

Sports Ledger is already discussing collaborations and partnerships with leading providers of wearable and Nano and bio-metric tech companies for the purpose of accelerating this revolution and to enhance the technological applications and techniques that will drastically improve the quality of sporting broadcasts for an even more innovatively spectacular approach.
