Exploring the world of blockchain technology reveals a digital revolution that is redefining our approach to transactions, removing the need for intermediaries, and enhancing the security and transparency of our online interactions. But as this digital frontier expands, a looming question arises: how will GDPR affect blockchain?
The EU General Data Protection Regulation (GDPR) governs how personal data is managed online. As blockchain intersects with these stringent regulations, critical questions emerge…
How can blockchain and GDPR coexist harmoniously? Is there a way to preserve the benefits of blockchain while respecting GDPR principles? And how to become GDPR compliant? Read on to understand these pressing issues and regulatory compliance.
Blockchain Technology
Blockchain is a type of technology that lets multiple parties store, share, and confirm data in a network without a central authority. Each piece of data, called a block, is linked to the previous one, forming a chain of records. Blockchain can be used to store and transfer any kind of value, such as money, property, or identity. It also supports making and trading digital assets like cryptocurrencies, tokens, and non-fungible tokens (NFTs).
Here are some advantages of blockchain:
1. Transparency
Every transaction in the blockchain is visible and traceable, showing where data comes from, where it goes, and when it happens.
2. Security
Blockchain keeps data safe and genuine by using codes and agreement from everyone in the network. It also removes the need for middlemen, lowering the risk of fraud.
3. Efficiency
Blockchain makes transactions quicker and cheaper by cutting out middlemen (In finance, blockchain enables direct money transfers without banks, reducing costs and delays for faster transactions). It also makes systems more scalable and compatible, letting different platforms communicate and share data.
GDPR Implications
Blockchain offers significant benefits but also poses challenges regarding data protection and privacy, particularly in light of the GDPR. So, how will GDPR affect blockchain?
1. Personal data identification
Blockchain stores diverse data types, including potentially personal data as per the GDPR's definition. However, identifying personal data on blockchain presents difficulties due to encryption, hashing (converting data into unique codes), or pseudonymization (replacing personal details with artificial identifiers or pseudonyms), making it hard to link data to individuals.
Additionally, some data may be inferred from other data, creating new personal data not readily visible on the blockchain.
2. Data subject rights
GDPR grants data subjects various rights over their personal data, including access, rectification, erasure, and restriction of processing, along with data portability and the right to object to automated decision-making. However, exercising these rights on blockchain is tricky because once information is on it, you can't change it, and the data is spread out over various locations under different countries' regulations.
3. Responsibilities of the data controller and processor
GDPR requires those in charge of data (controllers) and those handling data (processors) to follow rules like keeping data use minimal, purpose-specific, accurate, secure, and accountable. But, because blockchain spreads data across many places without clear leaders for data processing and protection, and might have security and management issues, meeting these rules is hard.
How Do You Ensure That Blockchain Is GDPR Compliant?
To ensure your blockchain website or application complies with GDPR regulations, follow these steps and tips:
1. Conduct a Data Protection Impact Assessment
Assess the risks and impacts of your data processing activities, especially with new technologies like blockchain. Determine if your website or application is necessary and proportionate, and implement measures to mitigate risks.
2. Choose the Right Type of Blockchain
Select the blockchain type that aligns with GDPR requirements and be mindful of what data is stored on the blockchain. Personal data should not be directly written to the blockchain, as it cannot be amended or erased once recorded. Instead, consider storing personal data externally and linking it via references generated on the blockchain.
3. Implement Privacy by Design and by Default
Integrate data protection and privacy into every aspect of your website or application. Use encryption, hashing, or consent mechanisms to uphold GDPR principles like data minimization and security.
4. Establish GDPR-Compliant Policies and Procedures
Develop and implement policies and procedures that follow the GDPR compliance framework for your blockchain operations. Utilize policy generators to simplify and ensure regulatory compliance.
