Researchers at the University of Southampton in the UK successfully stored the entirety of the human genome sequence onto an indestructible 5D optical memory crystal no bigger than a penny. The indestructibility claims are no joke since the discs can withstand temperatures up to 1,000°C, cosmic radiation, and even direct impact forces of 10 tons per cm2.
On that timescale, what are the odds that the checksum is still reliable?
Why would it be any different from the real data? Checksumming is basically just writing extra copies with math.
I’m asking why it would be more reliable if it has the same vulnerability to being corrupted.
Checksums are redundancy.
Right, but if the checksum is corrupted…
Yes Mr smarty pants, if all copies of data are corrupted the data is lost. More redundancy is more protection.
