For some reason I'm unable to quote the poster above, it said that post was deleted but I refreshed the page 10 times and it was there every time lol.
You got it all wrong, zap is not a blockchain to create any platform on it, LISK, NEO and Ξ are not hosting any content, they just add blocks and process transactions. even zap is hosted on a different server, transactions are handled by smart contract. this is something like nexus.social. I registered an account and I was talking to myself for an hour. lol
Zap is certainly not a blockchain but it is a platform that helps extend the list of potential use cases for smart contracts/dapps, building for Ethereum first with other smart contract platforms/blockchains to follow after.
