Eventual size of blockchain?

There is a hard limit as to how much information can be stored on a chip. It's just we havent reached it in 30 years.

So then store it in your body.

Just 4g of DNA could store all the digital information created in a year on the planet.

So you are including DNA computing technology in your investment analysis of bitcoin? This has not even been invented yet. It's just a concept. It is ridiculous to speculate on DNA storage - it's like talking about nuclear fusion.

Its clear that for the foreseeable future, storage is not unlimited, and also bandwidth is not unlimited. The unlimited size of the blockchain; the fact that anybody can add transactions for no cost, eg. SDice. The overhead with distributing an unlimited sized file to every node. IMO, that's the bitcoin end game - ignoring any government influence.

We're already seeing the beginnings of this problem with the patch from psi that's now available, that skips SDice transactions for miners.

Next-Generation Digital Information Storage in DNA

Digital information is accumulating at an astounding rate, straining our ability to store and archive it. DNA is among the most dense and stable information media known. The development of new technologies in both DNA synthesis and sequencing make DNA an increasingly feasible digital storage medium. We developed a strategy to encode arbitrary digital information in DNA, wrote a 5.27-megabit book using DNA microchips, and read the book by using next-generation DNA sequencing.

EDIT:
To be clear, I agree that block size should have a limit, although it will probably need raised to more than 1 MB at some point.

Sorry, I read your comment but I dont see how this article or paper contradicts what I was saying

Show me a link to amazon where I can buy a DNA computing device. Then I'll conclude that what you're talking about is more than just a concept.

RE: dancupid

"Moore's law" is not really a law. It was just an analysis by a guy 40 years ago who predicted a trend in microcomputing (that is computers getting smaller and smaller). For some reason this prediction has been given the word "law" but actually this is wrong.

Let me repeat what I said before. There is a hard limit to how much information can be stored on a chip. Its just we havent reached it.

Therefore the concept of distributing an unlimited sized file to every node on the network is fundamentally not sustainable or economical - READ: flawed. Storage will not be getting cheaper forever but under the current design of bitcoin, the filesize of blockchain will be getting bigger forever.

This analysis doesnt even take into account the bandwidth usage requirement as well, which will also be getting bigger forever.
