A recent advancement in molecular computing has led to the development of a functional DNA computer capable of solving complex problems such as chess and sudoku. This breakthrough, reported on August 22, comes from a collaborative team of researchers at North Carolina State University and Johns Hopkins University.
While DNA storage has been explored previously, this is reportedly the first instance of a DNA-based computer that performs both storage and computational functions without relying on electrical circuits. Instead, it uses biochemical processes to conduct its operations.
In testing, the DNA computer has successfully addressed computational challenges, including solving sudoku puzzles and chess problems, highlighting its beyond traditional digital computing.
Currently, most molecular computers are developed using synthesized DNA, which limits their application to experimental settings rather than practical use within living organisms. However, the foundational work demonstrated by this research opens the door to future possibilities. With sufficient development, it may become feasible to integrate computational systems directly into living cells.
The concept of a {blockchain} presents a futuristic application of this technology. In a cellular context, a blockchain network could theoretically be implemented inside an organism, with different cells functioning as validation nodes. This cellular blockchain could be used to monitor and verify cellular processes and integrity within specific organs, such as the heart or liver.
Although the concept of embedding blockchain technology within human cells remains speculative and far from current practical application, the breakthrough represents a significant step towards such advanced possibilities. The research underscores for future innovations that could merge biological systems with computational technology, bringing the idea of molecular computing and cellular networks closer to realization.
