How should it work to load videos (even sound, images) into the platform (=write into blockchain)?
The gas cost would be outrageous!
Large files won't be loaded onto blockchain, only the identifying parameters (i.e. hash in case of Bitcoin, smart contract in case of Ethereum etc.). Large files can be stored either by Notary Platform in the cloud or by the user locally. The Notary Platform will combine different uses of the technology.
