Abstract: Embodiments include a method of storing digital data in DNA storage by receiving the digital data from a user, deduplicating the data in a deduplication system of the user to form deduplicated data, and encoding the deduplicated data into a DNA string into a format for storage on a blockchain. A smart contract is deployed for deduplication on the destination side of nucleotide sequences comprising the DNA string, and the deduplicated nucleotide sequences are encoded into a Binary Aligned Map (BAM) format for storage as metadata on the blockchain. A process on the destination side synthesizes the deduplicated nucleotides for storage in the DNA storage, and stores the deduplicated nucleotides in the DNA storage as a next block in the blockchain only if the next block agrees with the smart contract.
