Yesterday the U.S. Patent released a patent application called "Blockchain System with Nucleobase Sequencing as Proof of Work". In the application Intel’s inventors describe a type of computer called a sequence mining platform (SMP) which would identify the order or nucleobases in a deoxyribonucleic acid (DNA) or ribonucleic acid (RNA).
Nucleobases are the molecules that make up DNA and RNA, which contain the genetic information within every living organism on the planet. The order of these bases determines what physical traits a person, plant or animal features.
The patent application states that the SMP would use a nucleobase sequencing unit to actually establish the order of nucleobases in a given sample, which would then be verified by the blockchain before being permanently recorded on it.
The POW algorithm will be used to both identify the sequence and subsequently verify it, according to the application, and the sequence recorded on one block would be used as a base for the POW problems in the next block.
