Can the blockchain, a distributed ledger technology that underpins cryptocurrencies such as the Bitcoin, be used to help millions of poor people gain access to financial services? Recent announcements by companies such as IBM and MasterCard suggest that it can, writes social venture capitalist Mir Haque in this opinion piece. Can blockchain technology, the decentralized peer-to-peer network underpinning cryptocurrencies such as Bitcoin, bridge the economic divide for the developing world the same way that the internet has bridged the information gap? Developments over the last few weeks make us hopeful that it can. Some 2.

FTP016: Vitalik Buterin – What is Ethereum and How to Build a Decentralized Future
Open access peer-reviewed chapter. Blockchain technologies, once used exclusively for buying and selling bitcoins, have entered the mainstream of computer applications, fundamentally changing the way Internet transactions can be implemented by ascertaining trust between unknown parties. In addition, they ensure immutability once information is entered it cannot be modified and enable disintermediation as trust is assured, no third party is required to verify transactions. These advantages can produce disruptive changes when properly exploited, inspiring a large number of applications.
These applications are forming the backbone of what can be called the Internet of Value, bound to bring as significant changes as those brought over the last 20 years by the traditional Internet. This chapter investigates blockchain and the technologies behind it and explains their technological might and outstanding potential, not only for transactions but also as distributed databases.
It also discusses its future prospects and the disruptive changes it promises to bring, while also considering the challenges that would need to be overcome for its widespread adoption. Finally, the chapter considers combining blockchain with Artificial Intelligence AI and discusses the revolutionary changes that would result by rapidly advancing the AI field.
In a large IBM survey recently conducted by top executives on blockchain [ 1 ] it was found that one-third of the almost who participated responded that they are using, or considering adopting blockchain in their business. According to the survey, 8 in 10 of those exploring blockchain are investing either in response to financial shifts in their industry, or for the opportunity to develop entirely new business models.
The proponents of blockchain talk about its great potential capable of creating the same type of fundamental changes as those brought over the last two decades by the traditional Internet. It is important, therefore, to explain blockchain and its unique advantages as well as its possible drawbacks and in particular the revolutionary changes that would result by integrating it with AI.
The purpose of this chapter is to investigate blockchain and the technologies behind it and explain its might and outstanding potential. It consists of three parts. The second part looks at its future prospects, including its utilization as a distributed ledger and the disruptive changes it will bring while also considering the challenges that would need to be overcome, including the fear of hacking and the possible fraud associated with the utilization of the technology.
The final part considers combining blockchain and AI and the breakthrough applications that could result from such a marriage. There is also a concluding section summarizing the chapter and suggesting some directions for future work. Blockchain is simply a decentralized, or distributed ledger versus the centralized ones kept by, say, banks to record transactions and keep customer balances of trustworthy digital records shared by a network of participants.
The authentication of information is done in short intervals of time and the updated information is stored appended to all participating network computers. Immutability and transparency : information can be appended only to previous data and, once entered, cannot be changed, modified or lost, providing a permanent, incorruptible historical record that stays in the system permanently.
Moreover, changes to public blockchains can be seen by all parties in the network thus ensuring transparency. Disintermediation : the ledger database is not maintained by any single person, company or government but by all participating computers located around the world. This means that two parties are able to generate an exchange without the need for a trusted intermediary to authenticate the transactions or verify the records.
Lower costs and greater speeds: lower transaction costs and greater speed are also characteristics of blockchain in a good number of applications by removing the monopolistic power of powerful intermediaries e.
The difference between the two is fundamental. The first disrupted business models in the s and created the likes of Amazon, Google, Facebook, Alibaba as well as Uber and Airbnb. Its disadvantage is that the information transmitted can be copied, thus making it impossible to guarantee its trustworthiness without the approval of an intermediary, for example, a bank verifying that the money being transmitted is available.
The biggest advantage of the Internet of Value is the establishment of trust, through the application of blockchain technology, between strangers who can now trust each other. This means assets can be exchanged in an instant and efficient manner without intermediaries who are no longer needed as trust is built into the system.
Such an advantage of the Internet of Value is bound to cause even more profound changes than those brought by the Internet of information. Trusted peer-to-peer transactions will encourage the formation of decentralized structures, diminishing the monopolistic power of intermediaries such as banks or firms like Uber and Airbnb [ 3 ].
At around the same time Estonia started implementing blockchain technologies in its governmental operations, including an ehealth record system that covered any one of its citizens who had ever visited a doctor.
Further applications were introduced in with smart contracts and decentralized autonomous organizations DAOs with huge potential thus fundamentally affecting the legal profession and the management of organizations see below.
However, the most significant applications are taking place since with a large number of startups working on innovative solutions that are going to change the economic landscape [ 4 ] and turn blockchain into a momentous technological force. These eight firms disrupted the economy and business sector by revolutionizing shopping and viewing habits, the search for information and advertising spending, among others, in ways no one could have predicted in the early s when the Internet was introduced.
Below is a presentation of what we believe are the 10 most important existing , or soon to be introduced blockchain applications, highlighting their usage and advantages and mentioning the startups that have been formed to develop and implement them. These applications have been classified in terms of the industries that are being affected and the various applications being pursued.
There is no doubt that many more applications will be introduced in the future, some of them becoming successful breakthroughs, in particular when combined with AI algorithms. It meets the highest standards of the banking industry, yet it is applicable to any commercial scenario. According to Business Insider [ 6 ], practically all major global banks are experimenting with blockchain technology trying to reduce cost and improve safety and operational efficiencies while, at the same time, making sure that they will not be left behind startups utilizing blockchain technologies to dominate the market.
By avoiding a central authority to verify payments and money transfers, costs can be substantially reduced. At present, there are a good number of services using the technology aimed primarily at those without bank accounts or those looking for important cost savings. Below is a brief description of six blockchain services located in various parts of the world. Abra USA is a mobile application allowing person-to-person money transfers. The app can be downloaded from Apple or Google stores.
Bitspark Hong Kong is an end to end remittance platform to any of their , plus locations worldwide. Rebit Philippines is a money transfer service offering significantly lower rates to the many Philippine immigrants working abroad. BitPesa Africa is a cheap and safe money transferring service operating in Africa. Blockchain technologies aim to reduce costs and speed up trading while also simplifying the settlement process.
For these reasons, many stock exchanges are considering introducing blockchain to their operation. The London Stock Exchange, the Australian Securities Exchange and the Tokyo Stock Exchange are already experimenting with blockchain technologies which are expected to be operational in the near future. Banks and financial companies are also exploring blockchain applications for security trading.
This means that any effort to improve health care services can result in substantial savings and blockchain technologies are prime candidates to achieve such savings while improving efficiency and probably saving lives at the same time. There are short-term blockchain applications ready to apply and ambitious, long-term ones aimed at revolutionizing the health industry. Security and trust: collect complete health data medical reports for each patient, history of illnesses, lab results and X-rays in a secure manner, using a unique identifier for every person and only allow the sharing of such data with the express permission of the individual involved.
Blockchain technology will eliminate the more than health data breaches, affecting over 27 million patients, reported in Exchangeability of information: health information between the various actors is not communicated freely creating silos that hinder its effective utilization to improve health care.
Blockchain technology can improve both the exchangeability of information and its quality leading to significant benefits. Claim settlement and bill management: facilitate claim settlement by reducing bureaucracy and introduce bill management to reduce fraud and speed up payment.
This can be achieved more efficiently by creating consortia of health providers and insurers. Blockchain technologies can address the issues through the time-stamped, immutable records of clinical trials. Most importantly, the technology could facilitate collaboration between participants and researchers and could contribute in improving the quality of medical research.
Estonia has implemented a blockchain application, eHealth, covering all its citizens. In addition, there are a number of startups like GEM claiming to have developed the first application for health claims based on blockchain technology. This is done by introducing real time transparency and substantially reducing the time for bills to be paid by the sharing of the same platform among those involved.
There are several other startups, some of which are already operating, and some on the way to becoming functional, like Guardtime, operating in Estonia and being used by patients, providers, private and public health companies and the government to store and access information from their eHealth system in a safe and efficient way.
Similar functions are provided by Brontech, an Australian startup, offering reliable health data to improve the diagnostic process among others; Health Co aims at revolutionizing the relationship between medical researchers and users; Factom, Stratumn and Tierion are mostly concerned with improving the quality of health data while the purpose of Blockpharma is to fight drug counterfeiting.
The multinational eBay is the leader for online commerce between consumer-to-consumer sales. OpenBazaar, is a new startup challenging eBay by utilizing blockchain technology to decentralize online person-to-person trade. By running a program on their computer, users can connect to other users in the OpenBazaar network and trade directly with them. This network is not controlled or run by an owning organization but is decentralized and free. Smart contracts are probably the blockchain technology with the highest potential to affect, or even revolutionize all sorts of transactions from the execution of wills to the Internet of Things IoT.
The major innovation of smart contracts is the elimination of trusted intermediaries. Instead of an executor, a programmable, legally binding smart contract can achieve the same purpose, using blockchain technology, avoiding the trusted intermediary, while reducing costs and improving efficiency. An additional, application of smart contracts is with IoT, facilitating the sharing of services and resources leading to the creation of a marketplace of services between devices that would allow to automate in a cryptographically verifiable manner several existing, time-consuming work flows [ 7 ].
Most importantly, such technology is the central principle behind Ethereum see below , a new extension of blockchain technologies focusing on running the programming code of decentralized smart contract applications. Such costs could be reduced substantially, using blockchain technology that will eliminate intermediaries by establishing trust between buyers and sellers. There are several startups, among them, Skuchain, aiming its blockchain technology at the intersection of payments letter of credit or wire transfer , finance operating and short-term trade loans and Provenance focusing on tracking the authenticity and social and environmental credentials of goods from the source all the way to the final consumer.
In addition to startups, big companies like Walmart, are also aiming at exploiting the advantages of blockchain technology to improve efficiency and reduce supply chain costs [ 8 ]. Blockchain could revolutionize the IoT if applied securely to the estimated 8. Exploiting the information generated by IoT devices intelligently can transform our homes and cities and have a profound effect on the quality of our lives while saving energy.
Eciotify, a startup, specializing in applying blockchain to the IoT, plans to roll out applications utilizing blockchain technology for IoT devices. Computer storage was decentralized in individual computers until about a decade ago when Dropbox was founded providing the first, modern, centralized cloud storage unit. Since then cloud computing was introduced revolutionizing applications by encouraging firms to outsource their storage needs to the likes of Amazon, Google or Microsoft Web Services.
The advantage of such services was lower costs and greater reliability. Blockchain technology aims to re-decentralize computer storage to individual computers all over the world. According to experts [ 10 ], there are three major reasons for such a switch. Second, there is greater security as blockchain data is encrypted, meaning that only users holding the appropriate keys can view it data stored in commercial cloud services could be viewed by third parties.
Finally, blockchain cloud storage is immutable while providing a record of all historical changes done on the data. One of the great promises of blockchain technology is that it can serve as a decentralized, permanently unalterable storage alternative for all types of information, or assets, not just as a currency or payment system. This makes the technology a prime tool for certifying all sorts of information, transactions, documents and records.
What has attracted the greatest interest, however, is the certification of data with the startup Stampery being the leader and of identities with the startup ShoCard being the leader.
There are many, additional areas where certification using blockchain technology can be applied including the issuing of IDs and even voting.
There are many additional applications exploiting blockchain technologies. Stratumn, a platform aiming to automate auditing, Synereo whose purpose is to aid users to create content, publish and distribute it online, Docusign offering the eSigniture solution and Steem, a social media platform where anyone can earn rewards, with some of these startups already operational while others are still being developed.
As interest in blockchain technologies increases, it is expected that VC investments will increase too accelerating the number of available applications. Enabling developers to build and deploy decentralized applications, serving specific purposes that become part of the blockchain network and as such not controlled by any individual or central entity which is the case of Internet applications. Exploiting the ethereum virtual machine EVM to run any desired program, written in any programming language, by using the EVM developers, without the need to create blockchain applications from scratch but can utilize the thousands of existing ones already available one type of such applications can be smart contracts.
Blockchain is becoming one of the most remarkable technologies since the appearance of the Internet [ 11 ].

Electronic Markets on blockchain markets
A crypto DAO , or Decentralized Autonomous Organization , was a concept that originated in among cryptocurrency developers. Their intention was to innovate on the traditional structure of a corporation by automating and decentralizing various processes usually conducted by human executives. Futhermore, crowdfunding via cryptocurrency can replace or augment regular funding conducted through stock markets. In simple terms, a DAO can be considered as any corporation that is run without the involvement of humans, exists mostly online and is so unbound by the laws of any particular nation, and is under the control of a set of incorruptible business rules. The implementation of these rules is done via open-source software that can be audited by the public and distributed through the computers of its shareholders. A human can become a stakeholder by either buying the stock in the company or when he is paid in that stock in exchange for the rendered services. At the centre of the crypto DAO revolution are the users. What one gets in return for his or her stake can have various forms. The tokens in this scenario can have many other applications, since they represent the usage rights of products or the rights of ownership that are tied to intrinsic value. The kinds of ownership stake Getting involved in any DAO can be done in three ways: 1.

Figure The fork meant changing the Ethereum blockchain so that The DAO hack had effectively never happened, violating the principle of immutability. This was a controversial decision that was resisted by some members of the community, who chose to continue with the unaltered version of the blockchain. In addition to creating Ethereum Classic, the Ethereum blockchain has been forked several other times to compensate for vulnerabilities and other changes in code. The only way to rectify the situation was to deploy a new contract and move the remaining funds over—a cumbersome and painful process.

Blockchain is a technology that allows transactions to be secure and anonymous. In short, blockchain creates a true peer-to-peer secure transaction. Blockchain has two main jobs :. Take a look how Blockchain expands to these industries. Today crowdfunding has an accountability problem. So what happens if you give money to the wrong campaign and someone misuses the money?

Vitalik Buterin to Audit La’Zooz Decentralized Ridesharing Project
Mark: Blockchain is an open decentralized, peer to peer, cryptocurrency technology that removes the middleman, making it a trustless digital ledger. Roanie: Blockchain is the technology that the first app — which was Bitcoin — was built. So, you have the Blockchain and then on the Blockchain, you have Bitcoin. You can also have more than one Blockchain, because it is a technology, and there are many different ways that it will grow. Guest : This process itself is transforming the industry, where third-party trust organizations, like banks, are no longer needed. Every transaction will be recorded on a public and distributed ledger accessible to anyone with an internet connection. Ethereum is the next biggest public ledger architecture after Bitcoin, which allows for Smart Contracts.
