Om relevant te blijven in een versnelde veranderende wereld, is er volgens Rick Bouter maar een antwoord mogelijk: Innovatie. En dat betekent dus ook kijken naar nieuwe technologieën. In deze blog legt hij uit wat Blockchain is en wat de potentie is van deze technologie.

Versnelde verandering lijkt in de wereld van vandaag één van de weinige constante elementen. Internetbedrijven schieten de grond uit als paddenstoelen en veroveren in elke maand of elk jaar complete markten die (soms sinds mensenheugenis) als gevestigde orde gezien werden. Hier kun je denken aan de bekende voorbeelden als Uber, die de taxi- en vervoersmarkt op zijn kop zet, Airbnb die dit met de verhuur van appartementen, huizen en kamers doet, maar ook aan Spotify en Deezer die de muziekindustrie in een compleet nieuw jasje steken. Verandering gaat dus snel, heel snel. Stilstand is vandaag de dag niet alleen achtergang, maar lijkt eerder op achteruitrennen. Een van de weinige vragen die overblijven voor bedrijven, organisaties en instellingen is: “Hoe blijf ik relevant in de snel veranderende wereld van morgen?”.

Innovatie is de enige manier om te winnen

Een concreet antwoord op deze vraag is even simpel als complex. “Innovatie is de enige manier om te winnen…” Als we deze vraag verder afpellen, komen we al snel bij de enablers van innovatie. Vandaag de dag is een van de grootste enablers en veroorzakers van innovatie het potentieel van nieuwe technologieën. Wanneer je dus wilt innoveren komt al snel het ongekende potentieel van nieuwe technologie om de hoek kijken. Internet of Things, Kunstmatige Intelligence, Virtual Reality, Nano technologie en Blockchain zijn veel gehypete en ook ‘over’gehypete technologieën.

Blockchain, een technologie met potentieel Laten we een van deze technologieën eens wat nader bekijken. Van programmeur tot boardmember: de term Blockchain geeft slapeloze nachten. Blockchain, de techniek achter de Bitcoin, kent veel meer toepassingsgebieden dan alleen cryptocurrency. Zo wordt gewerkt aan toepassingen in onroerend goed, containertransport, gezondheidszorg, muziekrechten, verzekeringen en pensioen. De technologie wordt door sommigen gezien als een innovatie vergelijkbaar met het internet. De grote vraag bij deze trend is: wat moet en mag je er nu mee?

Blockchain als digitaal vertrouwen

Blockchain is een technologie die het mogelijk maakt zaken te doen zonder tussenkomst van derde partijen. Bij deze derde partijen kun je aan allerlei organisaties en instanties denken. Van rijksoverheid tot gemeenten, van jurist tot ver¬zekeraar en van notaris tot kadaster. Deze derde partijen zijn ooit in het leven geroepen omdat wij, mensen, elkaar niet vertrouwen in het zaken doen of afhankelijk zijn van deze derde partij. We vertrouwen elkaar ten diepste niet terwijl dit een van de kernpijlers is van zakendoen. Een van de kernpijlers, net als andere belangrijke pijlers als een ruilmiddel (berenvel, goud, olie en bijvoorbeeld geld) maar ook het bewijs dat deze waarde maar eenmalig kan worden uitgegeven voor een bepaalde tegenwaarde. Blockchain als technologie waarborgt deze belangrijke aspecten van zakendoen en zou in potentie dus een belangrijke pijler in onze economie kunnen worden.

Hoe Blockchain werkt

Blockchain is de bekendste Distributed Ledger Technologie (DLT). Deze gedistribueerde grootboek technologie heeft als belangrijkste doel om een consensus te bereiken over zaken die over dit netwerk komen. Laten we even zaken doen als uitgangspunt nemen. De kern van zakendoen is een transactie van waarde. Deze waarde kan een huis zijn, een verzekering, maar ook gewoon een valuta. Blockchain is kort samengevat een computernetwerk waarin elk onderdeel van het netwerk een compleet overzicht van transacties heeft en dit op een decentrale manier opslaat in databases. Deze transacties samen vormen een block. Het laatste blok is ‘de waarheid’ waaraan niet meer getornd kan worden, dit waarborgt het gedistribueerde netwerk. Dit laatste block is dus de input voor het nieuwe block en de nieuwe transacties. Door de tijd worden meer transacties gevalideerd en komen er dus ook meer setjes van transacties bij (blocks) en zo vormt zich dus een digitale keten van blokken, een Blockchain.

Omdat deze waarheid omtrent transacties vastgelegd is over het gehele netwerk kan die vrijwel niet gemanipuleerd worden en is frauderen ook bijna uitgesloten. Op het moment dat er een transactie gedaan wordt, wordt deze gevalideerd door alle onderdelen in het netwerk. Deze onderdelen bevestigen de principes van zakendoen. Is er een waarde? Wordt deze waarde een keer uitgegeven? Komt er een betalende waarde voor terug? Wat zijn specifieke kenmerken van de deal? (Hierbij kun je denken aan tijdstip, betrokkenen en andere items die specifiek meegegeven kunnen worden.) Zo zou je kunnen zeggen dat de Blockchain een open grootboek is waarin alle transacties terug te vinden zijn. Door de rekenkracht die het netwerk ter beschikking stelt worden deze blokken gevalideerd door ingewikkelde wiskundige formules die niet zo maar iedere huis- tuin- en keukencomputer kan kraken. Degene die als eerste de transacties valideert krijgt hiervoor in ruil Bitcoins. Dit principe wordt mining genoemd. Nu zijn er uiteraard diverse mogelijkheden van een Blockchain want niet alles kan en mag open zijn. Zo kun je een publieke variant op Blockchain hebben waarin veel informatie open en bloot staat, maar ook privé Blockchains waarin alleen bepaalde geautoriseerde personen/ instanties toegang hebben. Ook hebben al diverse consortia van partijen die elkaar vertrouwen samen een keten op willen zetten.

Bij mijn vorige werkgever hebben we een whitepaper* geschreven over Blockchain met een sprekend voorbeeld erin. “Stel u beheert een systeem met fietshuurinformatie. Een klassiek systeem zal in de database een record hebben staan waarin staat wie momenteel welke fiets gehuurd heeft. Een Blockchainsysteem zal echter een ketting van huurmutaties hebben waarin de fiets toegewezen wordt aan klanten en weer terugverwezen wordt aan de eigenaar. Al deze mutaties zijn ondertekend door de klant en de eigenaar. Zo weten we zeker dat de transactie heeft plaatsgevonden en kunnen we ook opmaken wie de fiets momenteel in bezit heeft. Blockchain is digitaal vertrouwen, maar hoe zorgt het systeem ervoor dat alleen geautoriseerde personen mutaties doen op de database? Hier komt cryptografie om de hoek kijken. Elke deelnemer aan het systeem genereert een set sleutels, een publieke en een geheime sleutel. De publieke sleutel is een controlemiddel voor andere gebruikers om te controleren of berichten van jou ook echt ondertekend zijn met je geheime sleutel. Deze publieke sleutel is daarom ook niet geheim, sterker nog het is vaak je identificatienummer, bijvoorbeeld je personeelsnummer, of in het geval van Bitcoin: je portemonnee-adres. Stel een deelnemer aan het systeem wil een mutatie doorvoeren op de database, dan ondertekent hij het mutatiebericht met zijn geheime sleutel. Andere deelnemers aan het systeem kunnen met hun publieke sleutel controle¬ren of dat bericht ook daadwerkelijk door hem is ondertekend.” Bron: Caesar Overheid whitepaper: Blockchain, de hype voorbij.

Tot zover deel 1: “De impact van nieuwe (Blockchain) technologie.” In het volgende deel hopen we verder na te denken over de impact van Blockchain technologie op ethiek en kijken we ook breder naar technologische innovatie en haar impact op ethiek.

Blockchain Technology – A Cure for Pharmaceutical Counterfeit (1/2)

Big Data, Bitcoin, blockchain, Blockchain, data, Distributed Ledger Technologie (DLT), Innovation, Inspiring, technology, Trends, Trendwatching

Part I – Current status, Impact on the Industry

The use of Blockchain for the pharmaceutical industry has been speculated and discussed by many different entities and stakeholders for quite some time already. Blockchain is thought to address the burning platforms pressuring the pharmaceutical industry, and to possibly optimize its supply chain operations.

The burning platform in the pharmaceutical industry

The one big burning question in this context is whether the pharmaceutical industry is ever going to embrace the long awaiting digital revolution, or if they are going to bundle their forces in the act to avoid the inevitable? Although pharmaceutical R&D is driven by innovation, this feature is not so much blended into their general activities and operational processes. Already being one of the most conventional and traditional industries, the organizational hierarchy and strong fragmentation of the pharmaceutical industry only further strains the ability of companies to embrace novel technologies, such as Blockchain. Responsibility of patient health and safety carried by the pharmaceutical industry makes stakeholders rather hesitant towards novel technologies and rules out the opportunity of a trial-and-error-like implementation approach of technologies.

Blockchain in pharma, fighting the falsified instead of diseases

Regardless of their ignorance, the pharmaceutical industry has already been confronted with multiple burning platforms. Counterfeit is a continuously increasing problem across the pharmaceutical supply chain, conveying major consequences for patient health and company performance. Counterfeit products either contain a too high or too low concentration of the active ingredient, reducing the clinically proven efficacy of the product. Apart from a deviating dosage, counterfeit products may contain excipients being different from those displayed on the package, which may affect the efficacy of the active ingredient or cause unpredicted side-effects to patients after administration. Although in most cases this may only cause modest discomfort for the patient, in other cases counterfeit products can cause severe adverse events and lead to hospitalization or even lethality in its extreme. It is therefore necessary to eliminate pharmaceutical counterfeit, the sooner the better. To facilitate the pharmaceutical fight of the falsified, governments have enacted serialization regulations, obligating the pharmaceutical industry to make each individual product traceable along the entire supply chain. This allows every stakeholder to, at any given point in the process, confirm the authenticity of the product.

Trust, the challenge & the opportunity 

Circulation of illegitimate pharmaceutical products does not only put patient health and safety at stake, but also has a damaging impact on the business operations of pharmaceutical companies. As long as counterfeit keeps on existing, pharmaceutical companies are not able to assure quality and safety of their products. This has an eroding effect on their reputation as perceived by the patient as well as by other influential stakeholders, such as physicians, specialists, pharmacies, and regulatory bodies.

The inability of pharmaceutical companies to deliver product quality and safety has a direct effect on their revenue.

A decline in trust has a diminishing effect on sales. Additionally, sales of counterfeit products take away the incremental revenue of pharmaceutical companies. Thus, apart from protecting patient safety and product quality, the pharmaceutical industry is in an overwhelming need to safeguard and protect its reputation and revenue.

Curing the pharma counterfeit

Counterfeit products are incredibly difficult to identify by the naked eye, making it complicated to reveal and eliminate these products by human efforts solely. A technological tool with the capacity to enable end-to-end traceability could cure this pain point. Technically, Blockchain has the capacity to completely revolutionize the pharmaceutical industry, its processes, but above all to address the burning platforms and cure counterfeit. Its immutable character makes mutual trust and the need for intermediary parties redundant, while safeguarding secure storage and exchange of sensitive information.

Practically, however, unaligned objectives of industry stakeholders, a lack of trust in the technology itself, and the absence of willingness and often the guts to further explore the opportunities of Blockchain stagnates the utilization of these capacities.

As clearly described in Enterprise Blockchain: Are We There Yet? by Sebastian Wurst (Accenture Strategy, Munich), the unique value and at the same time the challenge is in developing a Blockchain solution that perfectly fits an enterprise setting. The abstractness and technical complexity should be converted into a commercial concept, in order to fully unlock Blockchain’s business value for any industry, and the pharmaceutical industry here in specific.

Blockchain in pharma: No success until mass adoption?

Along the way of praising Blockchain’s potential, we should not forget to touch upon the expected – disruptive – impact of Blockchain on company business models. Given the comparatively low extent of industry digitalization, current business models of pharmaceutical companies do not inherently support the implementation of a highly complex and abstract technology as Blockchain. Although some believe that Blockchain-enabled business models are on the rise, others recognize the need for only small adjustments to be made by the industry to successfully integrate Blockchain in their processes.

The largest adjustment required is said to be targeted at the mindset and core values lived up to by industry stakeholders and employees.

Cooperation, interoperability, and transparency are not naturally fostered by the pharmaceutical industry, being in an almost direct opposition to the core concepts of Blockchain. Additional education on Blockchain would increase the understanding of the technology, and possibly mitigate the risk anticipated to come with implementation. Altogether, the pharmaceutical industry may expect to be confronted with many different challenges along the way to adoption, making the successfulness of Blockchain an uncertain parameter. To address these challenges, it will require strong incentives to encourage and solid recommendations to point the pharmaceutical industry in the right direction and unlock the synergy between business and technology.

How Blockchain & the Internet of Things leverage and benefits each other

blockchain, Blockchain, Business models, Distributed Ledger Technologie (DLT), Innovation, Internet of things, IoT

Blockchain & Internet of Things (IoT), two very promising and big (r)evolutions in the digital world. Where Blockchain is promising us less interference of third parties, governments and institutions to provide almost the level of real trust in the digital world. Internet of Things on the other hand is giving us the insights we did never have and now can steer on. Insights that now give us real insights on the state of an external environment or the internal state of men, animal, application or whatsoever. Let us first have a quick look on the pro’s and cons of these two technologies before we dive into the content.

Blockchain key promises

First let us take a closer look to the key features and promises of Blockchain:

  • Digital Trust

Think about all possibilities of doing business and creating productivity without the interference of institutions and other third parties. The power of Blockchain at large is that we create an environment of digital trust to increase productivity. You even don’t have to trust the person you are doing business with because you both trust the technology.

  • Transparancy & decentralization

Blockchain is a system of decentralized and distributed databases. Everyone can have a copy of the data. Blockchain for that reason is promising for getting: the right person getting the right insights at the right moment.

  • Double spending

Value cannot be double spent in Blockchain. You cannot sell a house twice or spend the same banknote twice. Blockchain guaranties in its algorithm that double spending is impossible. You can be sure that you are the only one that owns the value.

  • Ownership

As a consumer of the Blockchain you want to be sure that the sender is the owner of the value. The cryptography that is used assures you that only the person with the private key can send the value to the receiver. So, it is very important that the private key is stored securely, ideally in an offline vault.

  • Smart Contracts

Most of the Blockchains support Smart Contracts. This is a very powerful feature. It is now possible to program trust and money. We found a quite good definition of smart contracting on Investopedia we would like to share.

Smart contracts are self-executing contracts with the terms of the agreement between buyer and seller being directly written into lines of code. The code and the agreements contained therein exist across a distributed, decentralized blockchain network. Smart contracts permit trusted transactions and agreements to be carried out among disparate, anonymous parties without the need for a central authority, legal system, or external enforcement mechanism. They render transactions traceable, transparent, and irreversible.

Smart Contracts Definition | Investopedia

 

Questions around Blockchain

Now let us have a look at some questions we have around Blockchain and Distributed Ledger Technology:

  • Security & privacy

There are a variety of questions that can be asked regarding security and privacy. How do I know that the Blockchain cannot be hacked? What is the impact of quantum computing on security? The right to be forgotten, how is that implemented? If everyone can read the data how do I secure that? Where is my data stored? How can I trust the data that is on the Blockchain? What are the possibilities of an Identity Provider? The list goes on and on, but we just wanted to give you an impression of questions related to security & privacy and Blockchain/DLT.

  • Regulations

A lot of people are focusing on the fact that there is less interference of third parties, and that is correct. The other fact is that they are replaced by others sometimes. Take the example of having your insurance via Blockchain, you still must trust the insurance company as an (e.g.) regulator in the process and an institution with the role to… You get the point.

Internet of Things key advantages

Now that we have discussed some of the many pro’s and con’s of Blockchain, we will dive into Internet of Things (IoT) and do the same with this technology:

  • Insights

The biggest advantage of Internet of Things is that we can steer on insights we never had before. Before the era of Internet of Things, sensors, Industry X.0 we steered on company data which quite often was incomplete, not accurate or not interpreted right.

  • Real time data

Another big advantage is the shift from historical data to (near) real time data. Internet of Things is helping us big time to steer on data of ‘this’ moment. That is also why IoT is one of the main drivers for elements like preventive and predictive maintenance.

  • Open data

Internet of Things is also a big driver in open data like weather and government data. Using this type of external and Big Data we can make data driven decisions and act on information we were not able to dream of a few decades back.

 

Questions on Internet of Things

After we have discussed the pros of the Internet of Things, let us have closer look at the downside of Internet of Things.

  • Privacy

With sensors, camera’s and other items on every street corner the question is how we can manage our privilege and right called privacy. One example how the Internet of Things is enabling for example a surveillance state is what is happening in China now.

“The Chinese government plans to launch its Social Credit System in 2020. The aim? To judge the trustworthiness – or otherwise – of its 1.3 billion residents”

The text above is the header of the article which appeared on Wired, called: “Big data meets Big Brother as China moves to rate its citizens

  • Security

Another item that comes to mind is the very unsecure state of IoT nowadays. With an increase of connected machines and products how can we manage a secure data storage and transport from (local) gateways to the cloud? With the definition of value changing from material & physical items shifting to data, cyberattacks and hacks are increasing and getting more and more damaging and larger at scale.

The strength of combining these two powerful technologies

There might rise a few questions when reading through this article. Why should I combine two technologies where I doubt items like privacy, security and safety? Here are a few applicable answers:

One of the big questions is: how can data on the Blockchain be trusted? This is where the power of IoT and Blockchain come together.  If the data generated by the IoT device can be used as an input for the transaction on the Blockchain then the input can be validated. But then the next question is raised, how can I trust the IoT device? Do you have to trust the IoT device? Off course most of the time the answer is yes. But for now, let us look at the point after the data is generated. We have summed up three reasons why the combination of the Internet of Things & Blockchain has so much potential and why it is worthwhile to dive into:

  1. Encryption and distributed storage

When the by sensor and actuator generated data is stored and encrypted on Blockchain technology this raw data can be transported to a distributed network. The question is however which data needs to be stored. A solution is to store all the data in a decentralized distributed cloud storage environment and add the hash of the raw data on the blockchain. You can therefor never alter the data because the hash will be different. Also, your transaction size is very low because it only contains a hash. You also can do this with complete documents or images.

  1. The perfect audit trails

With a growing number of networks and data the question of, what is real and what is not, is getting more and more valid. For that reason, Blockchain can be put into place to create a perfect audit trail to locate the source of, and connection between data.

  1. Trusting IoT devices

How can I trust a company? How do I know if a B&B is any good? Through ratings. Can I trust the ratings? Many times, not. The same question arises when consuming data from IoT devices. It is very likely that IoT devices get rated in the future. And yes, the ratings are on the Blockchain, so you can verify the if the rating is authentic. Another solution is to store all the valid public keys of the trusted IoT devices on a Blockchain.

 

Experiment and iterate to the moon and back

We would like to close the article with the following advice. All technological breakthroughs start with knowing the true potential of specific technologies. How often do you think that inventors were successful by ‘accident’? For that reason, it is important to give people the trust and budget to experiment with new technology and find out what the true potential is. When we know the true potential, we have a starting point to conceptualize the impact on tomorrows business (models) and we can start realizing the dream. That brings us to our last point, moonshots. Moonshots are often referred by as:

“A moonshot, in a technology context, is an ambitious, exploratory and ground-breaking project undertaken without any expectation of near-term profitability or benefit and, perhaps, without a full investigation of potential risks and benefits.” Source: TechTarget

So.., the big question, after reading this article is:

 

What moonshot are you going to take in combining the potential of Internet of Things & Blockchain?

Bitcoin: A Peer-to-Peer Electronic Cash System

Initial Bitcoin paper by Satoshi Nakamoto

Abstract. A purely peer-to-peer version of electronic cash would allow online
payments to be sent directly from one party to another without going through a
financial institution. Digital signatures provide part of the solution, but the main
benefits are lost if a trusted third party is still required to prevent double-spending.
We propose a solution to the double-spending problem using a peer-to-peer network.
The network timestamps transactions by hashing them into an ongoing chain of
hash-based proof-of-work, forming a record that cannot be changed without redoing
the proof-of-work. The longest chain not only serves as proof of the sequence of
events witnessed, but proof that it came from the largest pool of CPU power. As
long as a majority of CPU power is controlled by nodes that are not cooperating to
attack the network, they’ll generate the longest chain and outpace attackers. The
network itself requires minimal structure. Messages are broadcast on a best effort
basis, and nodes can leave and rejoin the network at will, accepting the longest
proof-of-work chain as proof of what happened while they were gone.
