Blockchain Immutability And The Right To Be Forgotten: Constitutional Challenges Of Blockchain In India

The rapid spread of blockchain technology across sectors such as finance, healthcare, land records, and public administration has created a constitutional challenge that Indian law is not yet fully equipped to address. Blockchain is a digital ledger shared among multiple individuals and is immutable in nature, enabling the recording of transactions and tracking of assets within a network, thereby providing a single source of truth. It operates as a decentralised database, where data is stored across multiple computers, making it resistant to tampering. A consensus mechanism is used to validate transactions in a blockchain, which ensures that there is agreement across the network. Blockchain derives its core value from immutability, meaning that once data is recorded on a distributed ledger, it cannot be altered or erased without affecting the integrity of the system. At the same time, Article 21 of the Constitution recognises the right to privacy as a fundamental right, which includes the ability of individuals to control their personal information, including seeking its erasure when it is no longer necessary or consented to. While the Digital Personal Data Protection Act, 2023, acknowledges this right, its framework struggles to operate effectively in decentralised blockchain systems. This paper examines this conflict. The paper addresses three key questions. First, whether the right to erasure, as part of the right to privacy, can realistically be implemented within blockchain environments. Second, whether the current legal framework in India, including the Digital Personal Data Protection Act, 2023 and constitutional principles, provides workable mechanisms to enforce this right. Third, whether it is possible to reconcile the technological features of blockchain with constitutional protections through legal or technical solutions. The study adopts a doctrinal approach, relying on constitutional provisions, judicial decisions, statutory law, and relevant academic and policy literature. The paper finds that the conflict is not merely technical but structural. In decentralised blockchain systems, identifying a responsible entity or data fiduciary, which is essential under the current data protection regime, becomes extremely difficult. Further, the proportionality standard laid down in Justice K.S. Puttaswamy v. Union of India (2017) requires that any restriction on privacy be narrowly tailored, whereas blockchain’s immutability operates in a blanket manner. The paper argues that there is a need for the State to develop clearer regulatory and technical standards to ensure that emerging technologies like blockchain function in a manner consistent with constitutional rights.
