QUOTE OF THE WEEK
“I can’t think of a field in tech that has had as much polarisation and as much useless noise as crypto. Behind all the noise, a lot of very clever people are quietly building highly complex and technical infrastructure, scaffolding and plumbing that might mean you could build billion-scale consumer services on this stuff in, say, five years.”

Projekt of the week: Enarxis – better management of EV loading stations
Enarxis project will use blockchain technology for reputation management for users of Electric vehicle (EV) loading stations, specifically in the hospitality sector.
Why in the hotel sector? Because EV loading stations have become as essential for hotel guests as WiFi was a few years ago. There are two problems: What if people reserve a station but then do not show up – but because of the reservation, the station is still blocked for use by others? Similarly, what if people load their batteries but then do not leave? Both issues will be managed with an app developed by the team behind Enarxis. The team was recently selected for an accelerator program by Visa and had earlier been funded by TruBlo.

How Russian Disinformation targeted a US movement
A report on how state-sponsored trolls from Russia targeted a movement (the Women’s March of 2017) and its leaders in the US. The goal was to weaken the movement by attacking the leaders and sowing doubt:
“They posted as Black women critical of white feminism, conservative women who felt excluded, and men who mocked participants as hairy-legged whiners. But one message performed better with audiences than any other. It singled out an element of the Women’s March that might, at first, have seemed like a detail: Among its four co-chairs was Ms. Sarsour, a Palestinian American activist whose hijab marked her as an observant Muslim.”
A second quote helps to understand how the tactics work:
“Ladislav Bittman, who worked for the secret police in Czechoslovakia before defecting to the United States, compared Soviet disinformation programs to an evil doctor who expertly diagnoses the patient’s vulnerabilities and exploits them, “prolongs his illness and speeds him to an early grave instead of curing him.”

Passwords: Why four random words are better than a complex phrase
Julia Angwin from The Markup shares a reminder on how to construct hard-to-crack passwords. The critical knowledge is that four random words (for example” “Sunshine Expected Today Brooklyn”) are hard to crack (because of the number of possible combinations) and easy to remember. There is no need for a complex, hard-to-remember phrase. For illustration, here is a link to an XKCD strip about this particular topic.
In her newsletter, she goes a step further and talks to Jeremi Gosny, an expert in the space of password security. They discuss how the need for safe passwords has changed. The critical advice: Make sure that you have a different password for all accounts, not the same across all your logins. The interview is interesting, and there are several relevant and recent observations in the space of individual password security.
Quote from the interview with Jeremi Gosny: “Where we find the most success as password crackers is targeting passwords that are generated by humans, because humans across the globe still tend to think alike. Despite our language and cultural differences, our brains are only capable of coming up with a finite space of patterns.”

The New York Times reports strong subscriber growth for 2. Quarter 2022
The New York Times is one of a few newspaper/news organisations that are successfully moving from the old print/advertising world to digital subscriptions. Developments are tracked worldwide in the hope of learning about potential patterns that could be applied to ailing news organisations elsewhere. The most recent update from the company is the second-quarter results for 2022. In total, 230.000 new subscriptions in one quarter mean that the goal of 10 million total subscribers could be achieved much earlier than planned.

Police at the door
In Germany, posting hate content in Germany can have direct consequences as a result of new laws.
“German authorities have brought charges for insults, threats and harassment. The police have raided homes, confiscated electronics and brought people in for questioning. Judges have enforced fines worth thousands of dollars each and, in some cases, sent offenders to jail. The threat of prosecution, they believe, will not eradicate hate online, but push some of the worst behavior back into the shadows.In doing so, they have flipped inside out what, to American ears, it means to protect free speech. The authorities in Germany argue that they are encouraging and defending free speech by providing a space where people can share opinions without fear of being attacked or abused. ‘There has to be a line you cannot cross,” said Svenja Meininghaus, a state prosecutor who attended the raid of the father’s house. “There has to be consequences.'”

Instagram allows longer stories
Instagram will allow longer stories. Stories shorter than 60 seconds will no longer be broken into small segments.
“Now, when you post a Story that’s under 60 seconds in length, it won’t be broken up into segments. The company began testing the change with select users late last year and has now rolled it out to all users worldwide…The new change is a welcome addition to the app, likely for both users and viewers. Users will now be able to post uninterrupted Stories that won’t be broken up, and on the other hand, viewers will no longer have to continually tap to get through a long video that they may not actually want to see. But, the change could also be a turnoff for people who liked the simplicity of short, bite-sized Stories.”

Podcast episodes are getting shorter
Based on an analysis of 2,5 million podcasts episodes with at least 10.000 listeners, Rephonic found that:
“Over the past nine years, podcast episodes that are at least 60 minutes long have slowly but surely become less common. They made up over 20% of all podcast content in 2013, decreasing to under 17% in 2021. Why? It could be the rise of short and frequent daily news podcasts. Or perhaps as podcasting becomes increasingly accessible, it attracts more indie podcasters with less budget to spend on producing long episodes.”
Other findings:
- The average top-performing podcast releases a 37-minute episode every 5 days
- The top History podcasts have the longest delay between new episodes
- Fiction podcasts should record longer episodes to attract a large audience

Digital Euro legislation planned for 2023
“At a conference hosted today by the Banque de France, EU Commissioner Mairead McGuinness said that the Commission plans to propose legislation for a ‘possible’ digital euro in 2023 to enable parliament and the European Council to debate it. The digital euro work is currently in the prototyping phase, and Banque de France Governor François Villeroy de Galhau confirmed that a decision on whether to proceed would be made at the end of 2023, with a potential launch in 2026 or 2027.”

Ethereum Merge reduced global energy consumption by 0,2%
“The Ethereum merge this week slashed global energy consumption by 0.2%, Vitalik Buterin wrote in a tweet Thursday, citing a crypto researcher. The long-awaited event successfully transformed the blockchain from a proof-of-work consensus mechanism to proof-of-stake. Proponents have touted the transition for making Ethereum an almost-net-zero technology. The switch also makes gas fees, or transaction costs, lower and means the network will be able to process transactions faster.”

Argentine airline to adopt NFT technology for tickets
Airbondi, a low-fare airline from Argentina, plans to issue flight tickets as non-fungible tokens (NFTs). This means that passengers can do more with them. For example, they can sell or transfer the tickets to other persons three days before departure. The underlying technology was developed by Travel X, and the company’s website is worth a visit. The company aims to reimagine travel using blockchain tech.

Bitcoin in El Salvador, one year later
Quote via “Attack of the 50 Foot Blockchain”:
- There’s almost no use of bitcoin as a currency. The official Chivo Wallet is hardly used, and they never did get it working correctly. Businesses have taken down their “we accept bitcoin” signs.
- There’s almost no use of bitcoin for remittances.
- Hundreds of millions of dollars in public funds have gone up in smoke — which is as if the US spent hundreds of billions — with nothing to show for it.
- Crypto crashed. As well as screwing over local bitcoin holders, this halved the face value of the government bitcoin reserve.
- El Salvador can’t borrow internationally. The IMF won’t talk to them while bitcoin is in place. The price of Salvadoran sovereign debt has fallen through the floor, as has El Salvador’s credit rating.
- The Bitcoin Volcano Bonds supposedly had $1.5 billion of buyer interest lined up — then Russia invaded Ukraine, and those buyers vanished.
- The ground has not been broken for Bitcoin City. I’m pretty sure it never will.

Is crypto a house of cards?
The Washington Post has a special about the story of crypto so far, chapter by chapter.
“Crypto is among the most urgent of current tech topics, driven by billions of cryptocurrency trades weekly — bitcoin and so many others — and a cultural stigma perhaps unseen in finance since the days of the Wall Street wolves of the 1980s. Almost since its creation, crypto has been characterized by sudden wealth creation, surprise hacks, big scams, bold promises and shattered dreams.”

Since the beginning of the SportChain project, when it all started as an idea, huge progress has been made. This progress consists of several individual milestones that have been achieved and are further explained below. SportChain is a two-phase project and is currently approaching the end of phase one.
Market Research
At the beginning of the project, we started with market research to determine the issues and needs of the sports and related industries to figure out where to place SportChain within this landscape. In this market research, the sports and associated industries, such as the betting and insurance companies, were involved.
Identified Business Opportunities
Through our market research and its results, we identified business opportunities. These opportunities supported us when designing the architecture and where the focus of SportChain should be directed.
Designed an Architecture
We have designed a SportChain architecture that drastically enhances the state-of-the-art digital processes within the sports industry. Also, we added features to increase data security, privacy, and trust in the sports data. The figure below shows the high-level architecture.

Figure 1: SportChain high-level architectural view including actors, components and main interaction flows
Implemented a Proof-of-Concept
Part of phase one was also the implementation of a proof-of-concept of the SportChain design. The most relevant parts are the SportChain portal, the integration with VIDwallet, and the integration with VIDcredentials studio.
SportChain Portal
The SportChain portal is the heart of SportChain. It offers the user interface between the users and the SportChain services. For instance, this portal will use team managers, league officials, notaries, and data reputation and analytics consumers. SportChain portal allows team managers to manage the team credentials, such as creating, issuing, or revoking player credentials. League officials use the SportChain portal to manage the league by issuing credentials for team managers and notaries and are also able to create matches and enter sports data that are being notarized by a dedicated notary afterwards. Last but not least, the portal offers a data catalogue that data consumers can use to search for data sets and statistical operations that will be performed on notarized data.

Figure 2: SportChain portal’s landing page with the different login options
VIDwallet Integration
VIDwallet is an SSI identity wallet developed by Validated ID. This identity wallet has been integrated into SportChain so that the actors can identify and authenticate themselves towards SportChain and also store and manage their digital identity data within their domain to ensure data security and privacy.
VIDcredentials Studio integration
VIDcredentials studio is a tool for credential issuers that provides a rich user interface with an advanced user experience. This tool is developed by Validated ID and has been adopted and integrated into SportChain, adding additional functionality to SpotChain. For instance, player credentials, special achievement credentials, or role credentials such as notaries or team managers can be issued and managed through this integrated tool.
Outlook
So far, exciting results have been achieved, but the journey for SportChain does not end here. Instead, the SportChain team is planning further to develop the platform, not only the basic functionality but also by implementing new exciting features. These planned features are detailed below in a short outlook.
Notarization Data Anchored on Blockchain
As data notarization is the process defined where a trustworthy party with special permissions, a so-called notary, verifies data and notarizes that these data are correct. This process can be performed in analogue and also in a digital way.
SportChain enables the data notarization of sports data, which have been entered by a league official. The notary verifies these data and confirms their correctness. In SportChain, the notarization process is based on hashing the data set that is being notarized, followed by timestamping and electronically signing these notarization data. This way, a verifier can verify if a specific data set has been notarized and also when this notarization was performed. As a new feature, SportChain plans to anchor these notarization data on a blockchain, in particular, on the Alastria blockchain. The benefit of having these data on the blockchain follows the general benefits of blockchains, such as transparency, immutability, decentralized and improved security. This new and exciting feature is planned to be implemented in phase two of SportChain.
Data Analytics Based on Notarized Data
Data analytics, reputation systems and forecasting systems (also known as Artificial Intelligence) have been hyped in recent years. This is because these methods offer enormous potential when applied correctly.
SportChain offers a data catalogue consisting of available data sets and data processing methods such as data analytics, data reputations and forecasting. All of these data processing methods use as input data only the notarized sports data. This way, the authenticity and integrity of these data are ensured, which elevates the trust in the calculated results. SportChain plans to implement data analytics such as various statistics and a basic reputation system that utilizes notarized input data stored on the Alastria blockchain. The reputation data could be used by a recruiting team to support their decision-making process. The benefit is the increased trust based on the ensured
properties data authenticity and integrity. This feature is planned to be released in phase two.

Ethereum Merge completed
This was a huge step for the platform. The new approach of proof-of-stake instead of proof-of-work will sharply reduce energy needs. How the change will affect the future of Ethereum remains to be seen. This week the cryptocurrency is down about 10%.
“The metaphor that I use is this idea of switching out an engine from a running car,” said Justin Drake, a researcher at the non-profit Ethereum Foundation who spoke to CoinDesk before the Merge happened.”

Microsoft Teams popularity results in new cybersecurity challenges
“…according to research released by Vectra yesterday, versions of Teams for Windows, Mac and Linux are storing authentication tokens in plain text on the underlying device. This is significant because it means attackers can gain access to authentication tokens and other information if they hack a system where Teams is installed. This vulnerability highlights that enterprises can’t afford to rely on the security of consumer-grade, public-grade communication platforms when they’re communicating sensitive information, IPs and other data.”

Should Apple be forced to use USB-C?
In discussions in Europe and the US, the goal is to have less “chaos” with charging ports. But not everyone agrees. If companies are forced to use a specific system, what happens to innovation in the long term? Quote from John Gruber, writing on Daring Fireball:
“Proponents of the EU’s USB-C charging port mandate speak as though bringing order out of chaos is still a problem to be solved in the mobile phone world, like it was 15 years ago. It’s not. Market forces generally work, and in the case of charging ports, they have: there are only two meaningful phone charging ports today, USB-C and Lightning. There is no chaos. There are good arguments for Apple to switch the iPhone to USB-C (high-speed data transfer, particularly for the 4K video footage iPhones have long been capable of, being at the top of the list), and good arguments against (zillions of iPhone owners with zillions of existing Lightning cables). But that should be for Apple to decide.” (Daring Fireball)

Market analysis: The state of crypto banks in 2022
Users: From October 2021 to May 2022, Crypto.com saw its user base grow from 10M to 50M, an increase of 400%. Similarly, the number of Nexo users doubled from over 2M to over 4M from September 2021 to May 2022. Crypto lending has surged over the last two years and publicizes a vision of financial services where lenders and borrowers avoid the traditional financial firms that position themselves as the gatekeepers for loans or other products.
Company size: While some crypto banks are facing hiring headwinds, others are unperturbed amid market volatility. In June 2022, BlockFi announced a 20% layoff — the company headcount dropped from about 850 in January to about 680 by the end of July. Meanwhile, Nexo’s LinkedIn headcount has jumped nearly 60% since January 2022.

Spyware use in Europe, homemade
In Greece, Thanassis Koukakis, a financial journalist, discovered spyware on his phone. This case seems to be part of a whole wave of spyware uses.
“Over the past 13 months, it has been revealed that spyware had targeted opposition leaders, journalists, lawyers and activists in France, Spain, Hungary, Poland and even staff within the European Commission, the EU’s cabinet-style government, between 2019 and 2021. The bloc has already set up an inquiry into its own use of spyware, but even as the 38-person committee works toward producing a report for early 2023, the number of new scandals is quickly mounting up.”
One key finding – the spyware was developed in Europe, not elsewhere:
“What sets the scandal in Greece apart is the company behind the spyware that was used. Until then the surveillance software in every EU scandal could be traced back to one company, the notorious NSO Group. Yet the spyware stalking Koukakis’ phone was made by Cytrox, a company founded in the small European nation of North Macedonia and acquired in 2017 by Tal Dilian—an entrepreneur who achieved notoriety for driving a high-tech surveillance van around the island of Cyprus and showing a Forbes journalist how it could hack into passing people’s phones. In that interview, Dilian said he had acquired Cytrox and absorbed the company into his intelligence company Intellexa, which is now thought to now be based in Greece. The arrival of Cytrox into Europe’s ongoing scandal shows the problem is bigger than just the NSO Group. The bloc has a thriving spyware industry of its own.”

A deep dive into the fall of Three Arrows
Long report about the founders, set-up and the reasons for the downfall of the crypto hedge fund. Apparently, “playing with money” was a big part of it, sheltered by a hybrid that the complex technology would make the blundering hard to detect.
“Bear markets in crypto tend to make any stock-market action look like child’s play. The crashes are so severe that insiders call it “crypto winter,” and the season can last years. That’s where Three Arrows Capital found itself by the middle of January 2022, and it was poorly equipped to weather it. The GBTC position ate an ever-larger hole in 3AC’s balance sheet, and much of its capital was tied up in restricted shares in smaller crypto projects. Other arbitrage opportunities had dried up. In response, Three Arrows seems to have decided to ramp up the riskiness of its investments in hopes of scoring big and getting the firm back on a solid footing. “What made them change was just overreaching for returns,” says a major lending executive. “They were probably like, ‘What if we just go long? In February, Three Arrows took one of its biggest swings yet: It put $200 million into a buzzy token called luna, which was founded by a brash, alluring South Korean developer and Stanford dropout named Do Kwon, with whom Davies and Zhu had been hanging out in Singapore.”

How a small, slightly different view might grow into deep distrust
Even if views on a complex issue differ, it should be possible to find a consensus for the best solution over time. A factor in this should be the amount of available information – the more, the better. That would be an assumption based on common sense. But it might not be true at all. Instead, the abundance of information might amplify small different views into deep distrust of “the other side”.
„We show that small biases may lead to substantial and persistent divergence in both trust in information sources and beliefs about facts, with partisans on each side trusting unreliable ideologically aligned sources more than accurate neutral sources and also becoming overconfi- dent in their own judgment.”
Could the abundance of information on the web and social media overwhelms and confuses humans? And that this leads to more extreme positions instead of compromise?

Dark Patterns: Bad when used by others, but ok when used by your company?
Benedict Evans points to two articles published in The New York Times: One criticising the use of “dark patterns” on technology platforms. And other technical articles where the news organisation talks about its optimisation to gradually funnel online visitors into subscriptions.
The use of technology to funnel first-time visitors gradually towards a possible subscription is not automatically a “dark pattern”. The expression describes UI/UX layouts of websites where users have difficulty saying “no”. Such patterns are used in all kinds of applications, often leading to complaints by users who only later find out they were tricked into consent for a setting, for marketing purposes or even a subscription which can not be cancelled anymore.
But Evans has a point that often, double standards apply to the use of
The technical report about using Machine Learning to gain more subscribers does not mention such approaches. But the point is: As everyone tries to optimise the business revenue, the occurrence of tricks, cover-ups and harmful business practices will likely not go down but up. One fact from the published article: After reaching 10 million paying subscribers, the NYT aims to reach 15 million by 2027. Such ambitious growth often applies tricks to achieve such goals in time. High pressure to reach goals was a significant reason for Volkswagen’s scandal around engine emissions.

In Argentina, Crypto is more practical for many transactions than cash
A recurring doubt regarding the future of cryptocurrencies (and blockchain) is the question of practicality. Where is the practical, day-to-day use?
One country where this is different is Argentina, a country where cryptocurrencies have a growing appeal, despite the volatility.
Two main reasons: The local currency, the peso, has lost value for decades. The second problem is that banks have imposed restrictions on bank accounts. Having a bank account in another currency with a bank outside of Argentina is no real option because one would have to travel there to get the money. This is why many people in Argentina store money they have in bricks – they buy bricks when they have money and store them.
“Argentinians who use crypto are increasingly untethered from the local Argentinian economy and increasingly plugged into the global cloud economy. Crypto is providing new solutions to problems that Argentina has faced for generations, and many Argentinians are excited about its potential to make it easier and safer to make, use, and store money.”

Bitcoin Depot to go public at an $885 million valuation
The company is operating a network of Bitcoin ATMs in the US.
“Founded in 2016, Bitcoin Depot claims to be the largest provider of such ATMs in North America with more than 7,000 kiosks in the region. These ATMs function by connecting with a wallet and, after a verification process, allow the user to insert fiat money to receive BTC, LTC or ETH in their wallets.”

The percentage of crypto investors did not grow in the past 12 months
According to a survey by PEW Research, the number of people dealing with crypto has remained at the same level as a year before, at roughly 16%.
(In 2020) Pew researchers asked 10,371 Americans if they have “ever invested in, traded, or used a cryptocurrency.” Some 16 percent of Americans said they had. Last month, the nonprofit asked another sample group — slightly smaller, at 6,034 Americans — the same question. And again, 16 percent said they had invested or traded in the alternate currency.

FileChain aims to extend existing, often complex document workflows with simple yet secure sharing options, similar to a decentralised blockchain platform. The underlying software is based on Java, making it more straightforward for many companies to adopt and customise their existing systems.
Currently, FileChain is a start-up company with offices in Sweden and the UK. Here is an interview with the founder and CEO.
INTERVIEW
Mirko Lorenz: You are the founder and CEO of FileChain. Can you briefly say what brought you there?
Sylvain Vittecoq: The original idea of why we created FileChain came from a day in 2016 when I realised that I had to provide input for my preference for a window or aisle seat on every airline website every time I would book a flight ticket. I thought there must be a way for me just to grant some airlines access to this one piece of information about my preference. This is how FileChain started. We are using distributed ledger technology to solve this kind of problem. My example was B2C. Decentralisation and delivery of such individual services are probably some years away. But for B2B markets, we are here with FileChain. Our software is a new way to provide blockchain distributed ledger services for B2B transactions.

Question: From your point of view, decentralised exchange of information blockchain functionality could help to free many workflows from having to file the same data again and again and again because we can access such pieces with the permission of the owner?
Sylvain Vittecoq: Everything is highly centralised. In any company, you will have ERP systems based on databases found in every single company and public administration. It is then the job of all integrators to enable these systems to talk to other systems with security layers to cross. Whenever there is an audit, there is a need to decide who can be trusted. My thinking is: By now, we can use a technology called the blockchain, which you can place in the middle. It is owned by no one but can be used by all parties involved to achieve a common goal. This approach puts the current logic upside down, and we can get there with a piece of technology placed between many parties with common interests. This opportunity is why I believe that this technology is not just a short-lived trend but that blockchain, in general, will succeed.
At what development stages is FileChain as a company? Is it a start-up? How is it funded through revenue or venture capital? How many people are working for you?
Sylvain Vittecoq: We are a start-up. We are less than ten people, which is still a small team. We got bootstrapped. We used our funding for development so far in stealth mode. We got a small investment in December 2020 from a UK seed investor. We are just running and financing our activities based on customers and incoming projects. We are still a relatively small company, with a substantial technical stack, which is now ready for production. We are just starting commercialisation.
What is your pitch to potential companies? Why should a company use FileChain?
Sylvain Vittecoq: We have a different vision for ledger technology. We don’t believe in public blockchains. Instead, we believe in federation or private blockchains which would be run and managed by a more comprehensive number of parties, and it might be a group of companies focused on supply chains for instance.
“We don’t believe in one ledger in charge of everything”.
Secondly, we don’t believe in one ledger in charge of everything, which does not make sense. Therefore, our ledger setup is different; we focus on the enterprise space. Thirdly, we want our blockchain ledger to be highly more economical than what is available today and way more performant. What needs to be understood is what it costs you to use specific software every day when everything goes well – and would I need to pay when something things go terrible. This is a fundamental question for every decision-maker.
Looking at specific blockchain tokens with gas fees, we think that many current blockchain use cases are based on speculation. It is almost impossible to predict what it will cost you down the road. You know, what will be your cost down the road. FileChain is none of that. We automate, but not through smart contracts because they are expensive and very slow to run. We do our automation, but differently. If anything goes wrong when using new blockchain platforms, no one can provide actual liability. FileChain is different here: We want to make sure everyone knows from the start who would be blamed for what and who would have to pay what. Our focus is not on smart contract utility tokens but on a decentralised ledger that can reliably transport documents between parties, the right legal professionals. And I mean regular contracts, not smart contracts, actual, regular paper-based contracts. For example, we believe that it is possible to achieve a significant change in how to handle paper and permissions in the global shipping trade. There is an immense potential to save money and drastically reduce current operational costs. Implementing news ledger technology could generate new revenue streams because the new features can disrupt the current market and create a new market.

“We don’t forget the old world. We aim to integrate ERP solutions with blockchain.”
So, in other words: FileChain is a modern approach to cloud storage that uses some aspects of a blockchain. So FileChain creates a bridge between the old world and the business world of the future. Is that correct?
Sylvain Vittecoq: Yes. We don’t forget the old world. We aim to integrate ERP solutions with blockchain. We simply don’t forget large companies that have invested 100.000s lines of code. Our technology is a true full-stack ledger from layer 1. So, we have no dependency on any other ledger. This is not a fork of the code from Ethereum, Bitcoin, or any other token platform. Instead, this is 100% FileChain code for the nodes. These nodes have the task to verify the signatures of all the transactions. Those nodes would be one piece of software. We also have an agent, which is the other piece of the software we provide, for people to send or receive millions of transactions. Our goal is to make this much cheaper and more performant than today.
Could you describe a typical company from a specific industry that is a FileChain client?
Sylvain Vittecoq: We are getting traction because we not only provide file and data exchange. On top of that, we can implement transactions to transfer value from A to B. We offer a complete toolkit to underpin the needed paperwork for many types of transactions. Shipping is a good example. You may want to have many companies being able to onboard and identify themselves. This is what they can do with our ledgers. Once they have a public-private key pair, they can authenticate themselves and provide all the required documentation to identify everyone on that ledger fully. Even the shipping containers could authenticate themselves with a serial number and some keys. This is the perspective for the future: A shipping container could send a document or form in JSON XML. Someone from a shipping company could send a Word or a PDF document to another entity present on the ledger. That is the focus of FileChain: To streamline paperwork for all types of transactions – before we get into a transfer of value, which – we believe – is at most five per cent of all the transactions needed for many types of business.
Logistics and shipping are the focus of FileChain for now?
Sylvain Vittecoq: Many of our current use cases are in shipping because there is a lot of paperwork. We are supporting supply chains because you must trace everything. But such a system helps track any valuable goods or many companies. Another use case is when you need to follow valuable cars, watches, or other luxury goods such as art. All such workflows will require packaging the correct information and sharing it with specific people or companies. And never share anything with anyone else. That is another crucial element of FileChain technology, as we offer privacy by design.
“I can decide to share it, in that second, that hour, within days or even months, to share the same content with one or 5000 other recipients instantly”
What you offer is a modern way to exchange information, but with a specific and innovative approach how to share sensible parts such as a person’s name, address, bank account, and so on?
Sylvain Vittecoq: Let’s say I want to share a document with you using FileChain. I can do this using drag-and-drop from my desktop. Encryption is added automatically. When the file leaves my computer, it is now embedded as a FileChain transaction as in-chain storage. Once the transaction gets into the ledger, I’m still the only one who can decrypt that content. I can decide to share it, in that second, that hour, within days or even months, to share the same content with one or 5000 other recipients instantly. I am not going to clone that document again on the ledger. Instead, I will give everyone access to that same content sitting on the ledger. I have complete control over who can access this information. I can even reverse access.
What is the technology you use for FileChain? Is it a specific blockchain protocol?
Sylvain Vittecoq: FileChain is a full-stack offering, and our reference implementation is in Java, which means we have no dependency on anything else. So, no exotic language. And, going back to my initial point, we don’t forget the work that has been done before because older systems are already running and existing today. This is the reason why our reference implementation is in Java. We have a full-stack offering from Layer 1 up to the SDK, including rest APIs for anyone to implement the business logic into other applications. This one ledger can run multiple applications with multiple use cases.
Is it that many clients want to use the benefits of the blockchain approach but have to be able to understand the language in use?
Sylvain Vittecoq: That’s precisely why we do not use a language like Solidity, which is used for many smart contracts but is to some extent prone to errors. From a liability standpoint, this is a no-go. Because in many business settings, you cannot guarantee that the smart contract will execute as intended. So that’s why we don’t have smart contracts for FileChain. Our focus is different: We want to have an application that many engineers can work with efficiently, which they can connect with existing ERP systems quickly. Through such projects, blockchain can achieve mainstream adoption, in our view. To get there, we need a low barrier of entry for software engineers. This is the same for the hosting and the management of those infrastructures. With FileChain, we have a straightforward set-up for the network and to join additional nodes. We don’t want people to spend a lot of time building many tools. That is pointless. What you want is just to get done with your actual business so that you can save money or make money. It is precisely what we try to achieve every day.

Would you be open to collaborative projects? For example, could creators of other innovative distributed concepts work together with you? Or would that be complex?
Sylvain Vittecoq: Partnerships are, at the same time, simple and complicated. Simple in the sense that our core technology is Java. We should exclude the full integration of an ERP system because such work is often complicated. A marketplace, for example, can be created in some days or maybe a few weeks by just one Java engineer. So that is the yes path to the answer. Indeed, if we want to participate in an App in creating a particular ecosystem, we can very, very quickly do that. Our technology allows for very short development cycles, as we are already starting from something substantial. The no part is that we cannot do it for free. We would have to look carefully at the possible benefit down the road. We are already partnering with many large system integrators. We like to work in sandboxes to make something with others, and we welcome partners.
What are your plans for the future of FileChain?
Sylvain Vittecoq: We are 100% “Made in Europe”. And we want to remain with this DNA. I am increasingly meeting people from France, Germany, and other parts of Europe who share a common understanding that we need to create momentum in that direction to not end up with solutions and companies from the US running every blockchain-oriented project in Europe. That is one part of the reason we want to be an example.
We are 100% “Made in Europe”.
We aim to maintain an excellent knowledge of all the European regulations. So that all our customers, wherever they are on the planet, FileChain ledgers will match all the regulations as applicable in Europe. This is basically what we try to drive forward, who we work with, and how we work. We have always been told our technology is very different, and our point of view is very different. Based on this approach, we are getting a lot of traction.
