In November, the EU’s plans to ban all privacy coins were leaked, sparking a debate in the crypto community. The transparency of blockchain is perfect for many use cases but not for others. Zcash, with its zero-knowledge proof technology, helped set a precedent for privacy-focused cryptocurrencies. However, the leaked EU plans would outlaw privacy coins like Zcash, dash, and monero, impacting the entire EU economy. Governments are not always against blockchain-based privacy, as seen with the collaboration between David Chaum and the Swiss National Bank on a privacy-protecting CBDC.
Chaum’s technology aims to provide privacy like cash but traceability like bank transfers. However, privacy is easily lost, as seen with state-backed surveillance laws in countries like Russia and China. The United States and the UK also have laws allowing for online surveillance and data collection. The crypto community is hesitant to accept these standards on their platforms and is working on technologies that prioritize user privacy by design. It is essential to build technologies that uphold privacy, security, freedom of expression, and access to knowledge.
Governments need to find a balance between privacy and security in blockchain technology. Certain sectors like healthcare and finance require privacy. New blockchain use cases demand privacy to operate effectively. Projects are leveraging encryption and zero-knowledge proofs to provide solutions where data remains private but verifiable. The year 2023 is predicted to be a crucial year for privacy in crypto, with builders, users, and advocates playing a significant role in shaping a more balanced system. The ongoing debate between security and privacy continues, with privacy coins at the forefront of this discussion.
