Blockchain technology is celebrated for its transparency, offering a clear record of every transaction. However, this transparency can also be a double-edged sword, as it exposes users to potential risks such as targeted phishing attacks. Moreover, the open ledger of blockchain could unintentionally lead to a concentration of power among those who can exploit this transparency. To address these challenges, there is a growing emphasis on giving users control over their data ownership on the blockchain, enabling them to choose what information remains public and what stays private. This approach aims to strike a balance between transparency and user autonomy, ensuring that blockchain technology continues to empower individuals while mitigating privacy concerns.
