“A whitepaper written by Astyanax Kanakakis and Vitalii Demianets describing a distributed ledger protocol that incorporates a deletion mechanism without compromising the security of the blockchain.”
Abstract: One of the core attributes of distributed ledgers, the immutability of recorded data, presents serious challenges when regulation prohibits permanent retention of information. In those cases, entities storing personal data are legally obliged to delete it at the request of the data owner (“right to be forgotten”). This whitepaper describes a distributed ledger protocol that incorporates a deletion mechanism without compromising the security of the blockchain. Its core thesis lies on securely retaining cryptographic linkage between all components of the blockchain, even after record modification, with the introduction of a new type of transaction and Merkle Tree creation. The paper is targeting general audience involved in record keeping operations. A technical yellow paper will be released in the coming months.
