Thank you @cryptogem? How much memory would one persons device need to loan to the blockchain to be able to track data of billions of devices, cryptocurrencies (bet there will be several) & other tech just to be able to make this system workable. Will they have several different blockchains for different purposes? Such as, 1 blockchain for 1 currency. Another single blockchain for IoT (internet of things devices). Etc..
I understand blockchain bundle data data will simply be encrypted text data (probably compressed as well), but still very curious once the blockchain becomes a thing of the norm & everyones device (laptop, smartphone, etc.) will be keeping record of the blockchain(s), how much free space in Mb or Gb would be required?
