According to Cointelegraph, scientists from North Carolina State University and Johns Hopkins University have achieved a significant milestone in molecular computing by developing a functional DNA computer. This advancement, detailed in research published on August 22, marks a potential shift in how computing could be conducted in the future, moving from traditional electronic systems to biological ones.

DNA storage has been explored for some time, but this new development represents the first instance of a molecular computer capable of both storage and computational functions using DNA. Unlike conventional computers that rely on electricity, this DNA-based system operates through molecular processes. In initial tests, the DNA computer successfully solved complex problems such as sudoku and chess, showcasing its computational capabilities.

Currently, most molecular computers are created using synthesized DNA, which means practical applications involving their integration into living organisms are not yet feasible. However, the foundational research suggests that with adequate funding and motivation, it could be possible to develop computation systems within living cells. Future advancements might even enable networking DNA-based computers within a single organism, opening up new possibilities for biological computing.

One intriguing concept is the idea of a blockchain network operating inside a human body. Similar to traditional blockchain networks, different cells could function as validation nodes for transactions occurring on a cellular blockchain. This could theoretically allow for the creation of a cellular blockchain network within specific organs, such as the heart or liver, to validate their function and verify cellular integrity. While this technology remains speculative and beyond current capabilities, the recent breakthrough brings it closer to reality.
