The Core Principles of Blockchains

Such options, which aim to patch privacy vulnerabilities as they arise, also have the secondary effect of demonstrating the importance of implementing privacy from the start. While some of these add-on options are essential in business environments, it is almost impossible to ensure all vulnerabilities have been repaired. But when privacy is by default and implemented from the start, it is much more likely to be effective. If we are talking about blockchain, the stakes are even higher.

With blockchain, privacy by design is the only option. With the introduction of the GDPR, the concept of data protection by design and by default has been signed into law. It is no longer just great advice as outlined by Dr. Cavoukian, the former Privacy Commissioner of Ontario, Canada, continues to be to be a champion for privacy by design.

While we speak in general terms about privacy by design, the GDPR deals with the specifics of data protection , which I approach as a subset of privacy. Back in Berlin! Data Natives , in person and online - tickets available now! From a high-level perspective, blockchain effectively enforces parts of the Privacy by Design framework, and practically leaves it as the only option.

Due to the immutable nature of blockchain, there is simply no other way than to apply it from the very beginning. Protocol or dApp developers could face liability issues if this is not implemented correctly from the start.

Analyzing each of these principles within the context of blockchain offers insight into the greatest challenges for blockchain in privacy by default and privacy by design. The basics are easy — and really the only option for blockchain privacy. But you will have to think this through to the end, and that can be challenging. If usage patterns or interaction can be linked back to a natural person, you should already be careful about having this information out in the open.

While encryption can bring a lot of advantages, you should still live under the assumption that it can be broken one day — and in the case of public ledgers, you will end up facing a problem. So it is important that when no action is taken by the user, the default option is the most privacy-friendly option, which collects only data needed for the legitimate purpose that has been explicitly defined.

Article 5 1 b , purpose limitation. For example, a private transaction within a cryptocurrency, that can be revealed if the parties so desire, is a much better option from a privacy point of view , than one that is public but pseudonymised through a wallet address.

Perhaps usage patterns, either now or in the future, may reveal more personal data than originally intended or foreseen. While encryption is helpful, it should, as the GDPR and the guidance suggests, be seen as a technical measure to protect the data, and not as a way to anonymize it. Encryption algorithms may be broken in the future, at which point all encrypted data on a public ledger is indeed, public.

Major data breach! Privacy should be considered at the design stage, and be applied consistently throughout the product or service. Small flaws or overseen points can have oversized bad outcomes, particularly in a blockchain environment. Is additional information collected on another level, and can this be related back to a natural person or lead to singling out?

To do this properly, all system layers should be evaluated. In blockchain, privacy and functionality can co-exist. Most implementations dealing with personal data will only store the verification on the blockchain, and keep other parts of information elsewhere.

This way, there is no need for a trade-off between privacy and functionality. Innovation can still happen in a privacy-preserving regulatory environment, and the GDPR is no exception. Blockchain offers great possibilities for giving the data subjects full, uncompromised control without the need for personal data to live in central containers that are not only in the control of a single party, but are also vulnerable as high-reward attack targets.

Decentralized, blockchain-based self-sovereign identity solutions are a great example of increased privacy with a user experience that meets or exceeds current identity services. When using blockchain, it is easy to deliver on the integrity of the data. The concept of blockchain is immutability, and if therefore tamper-proof, ensuring that data can be deleted only by having a clearly breakable link to any personal data.

This means no information on the blockchain should be able to be re-linked to any personal data once the link is purposefully broken. To achieve this, the current best practice is storing only hash-proofs on the blockchain that include a secret piece of information that can be permanently deleted, or even better, by using zero-knowledge proofs.

Blockchain is transparent by nature, so this principle should be easy to uphold. The recommendation of Privacy by Design is to verify that the business practices or technology involved are, in fact, operating according to the promises and objectives they have defined. Within public blockchain environments, not only the code, but also the data generated, is public and can be verified.

At times, blockchain could be a little too transparent; every participant in public networks, can see everything. Operators and architects of blockchains should keep the data subject and their privacy in mind in all stages of designing and operating the system. This is particularly important at the start of any blockchain protocol design as what has been stored on a blockchain is immutable, and cannot be deleted or reversed in the future.

On the other hand, blockchain technology also has the ability to give users control over their personal data through self-sovereign identity systems. The user has control over where the data is stored, on their own device or elsewhere. This is protected against falsification by storing the third-party proofs and no actual personal data on the blockchain.

This allows users to reveal their identity or only parts or proofs thereof to other parties of their choice. Privacy by design includes a set of important principles now deeply embedded into the GDPR. It is no longer optional to consider and implement the principles and related requirements. Especially with blockchain, there is no alternative to implementing privacy by design from the start, as the usual add-on privacy enhancements simply will not satisfy the requirements of the GDPR.

This short paper is to be seen as a primer of potential further work on the subject of how to properly practice privacy by design using blockchain technology. There are a variety of examples and ideas available, most of them initiated or developed by Dr. Ann Cavoukian, to be evaluated with the constraints and opportunities of blockchain. Future work could also include evaluations of how specific blockchain projects implement or practice good privacy by design.

New to the concepts of blockchain? Join the crowd. I'm breaking down what I read into the simplest possible terms, in hopes that someone as clueless as I am might walk away with a slightly better understanding of this potentially revolutionary technology. In the first entry , we focused on the basics of what makes blockchain, blockchain. Today, we're on chapter two, which focuses on the seven design principles of an economy based on the technology. The basic principle: Because the blockchain is spread out over thousands of computers, it is "networked", and the participants in a blockchain economy are incentivized to maintain "integrity", as every interaction is indelibly recorded.

These attributes have caught the attention of researchers and developers interested in applications and environments where the need for the integrity of identity and content are as paramount as the safe delivery and record of transactions. Self-sovereign digital identity in particular is often cited as a human right that nation states need to embrace with as much conviction as education and lifelong learning are considered to be a public good. Although the blockchain has long been identified as an opportunity for driving much-needed change in the core processes of the education sector, use cases to date have been limited in scope and execution, with blockchain advocates and education policy makers seemingly disconnected on fundamental issues such as governance, self-sovereignty, interoperability, choice of blockchain platforms and overall trust in standards and the integrity of the infrastructure. This article is primarily interested in the affordances of the technology as a public good for the education sector. Once exclusively circumscribed to the fintech sector, blockchain technology is now identified as a force of change in multiple realms of operation including public sector services such as healthcare, voter identity registration, asylum process management 3 and higher education. In a recent report, the American Council on Education Lemoie and Soares, identified three key themes emerging from the intersection of blockchain technology and education: personal data agency, lifelong learning, and the power of connected ecosystems. While lifelong learning has been a recurring theme in the education sector for several years Ates and Alsal, ; Volles, , the concept of personal data agency as achieved via self-sovereign identities is still gaining momentum in academic and policy circles Wang and De Filippi,
