Definitely our ultimate aim is to make Toqqn a completely decentralised app; but not sure how long that would take or how far we could go with the complexities that might occur on the way; also the blockchain technology is still limited and new to be used as the sole technology for a big social platform.. But yes, we intend to make it to a dapp and we will be doing our best.
Initially we will be using conventional technologies to build the platform; just like any other social media website. Then on phase two we will be decentralising all the personal user data - so only the content (posts, comments etc stuff) would be centralised. Inter-website user communication is also scheduled with the phase two and the data of the same would also be decentralised.
We will have more detailed information once we reach the development state to phase two.
Are you going to make the social platform a dapp project?
