Title: Fused quartz for private keys and eternal blockchains? Post by: marcus_of_augustus on February 18, 2016, 02:41:51 AM http://hardware.slashdot.org/story/16/02/17/1931200/data-written-with-superman-memory-crystal-could-last-billions-of-years (http://hardware.slashdot.org/story/16/02/17/1931200/data-written-with-superman-memory-crystal-could-last-billions-of-years)
Quote Researchers have demonstrated a method of femtosecond laser writing in self-assembled crystaline nanostructures that can withstand temperatures of up to 1,000 degree Celsius and last indefinitely at room temperature. The storage method enables up to 360TB of capacity on a single disc. Data is written to a file comprised of three layers of nano-structured dots separated by five micrometres. The technology was first demonstrated in 2013 when a 300 kilobit digital copy of a text file was successfully recorded in 5D digital data by femtosecond laser writing.

That's some great new technology. It does seem like it will take years before we see that kind of permanent memory in products. A good technology for permanent memory is not available yet IIRC. If accessing that information is fast, then it would be easy to store & use the whole blockchain. And have room for whole lot more. Then I guess we are back to the issue of speed of moving data around. Title: Re: Fused quartz for private keys and eternal blockchains? Post by: 7788bitcoin on February 18, 2016, 04:26:29 AM I think at the moment it is still a very expensive technology. Hopefully it will be cheaper in future. For bitcoin's blockchain data, it will need to be a system to allow continuous addition of data...

Even if it became very popular and easy to manufacture, if you could get 320 TB of data on a disk for cheap, how much would a 1gb USB cost?

Post by: Kakmakr on February 18, 2016, 06:08:34 AM Superman will be proud of the human race now. ^smile^ Just when we thought the technology they used in the movie, was far fetched, it becomes real. You can now make your backups on salt crystals. ^Whoaa^
It is a very interesting concept and we have a abundance of quartz, so the storage media will possibly be cheaper. Who would have guess, go go Clark Kent!

You can look at the price of memory over time: http://www.jcmit.com/memoryprice.htm In 1957, 1Mbyte would cost $411 million; In 1977, 1Mbyte would cost $36,800; In 1997, 1Mbyte would cost $2.16 By 2015 Dec, 1Mbyte would cost $0.0037... |
