Blockchain Storing Genomes

Makes sense,  encoding. 

Blockchain Can Secure, Store Genomes

YaleNews, Bill Hathaway, June 29, 2022

The SAMchain technology developed by Yale University scientists leverages blockchain to give users control over their own genomic data. SAMchain guarantees the security of individual genomic information, shielding it against change by others and the occasional corruption of cloud-stored DNA data. The researchers circumvented the problem of storing vast datasets derived from genome sequencing by comparing an individual's DNA against a standard reference genome, then storing only the differences in linked blocks of the blockchain. The blocks are subsequently indexed to enable rapid inquiry, and those differences can be connected to conditions with known genetic risk factors. "We think this will actually make genomic research easier," said former Yale researcher Gamze Gürsoy. ... '
