#blockchaindev question. So we have web-api, some fediverse instance, where user could be identified by public key (available in json representation of user account).
Also we have some smart-contract on blockchain, which could be used as #DAO for fediverse instance - voting, managing funds etc, bound to instance. Is there a way, when user will be signing up to DAO, to verify that he belongs to specific instance

Which one of this is going to win smart-contract race )

3/3 Ongoing hype is about DeXes and building your own DeX blockchain is still more complicated then just deploy smart-contract on Tezos. And it looks for me that polkadot will loose this race. But only until mass adoption of cryptocurrencies, which will perform massive DDoS attack on single-chain systems. Like in 2017, when it became obvious that bitcoin is not for buying coffee, same will be with single-chain solutions
So, is this analysis correct or am I missing something?)

2/3 ... and polkadot offers security for them. This gives 2 main advantages:
- no bottleneck, cryptokitties will not affect your dex
- you could have any feature as fast as you can
For example Tezos is going to implement zero proofs, and I found at once substrate parachain on github with zpk. Solana have unique consensys, you could have it on your parachain as well. Even blockchains with sharding, which could fix bottleneck issue, still could not compete here

1/3 I'm looking for blockchain job, as junior developer, and generally I'm focused on polkadot/substrate, but also like open for other options. That's what my profile on job site says) And I was contacted by several teams, with offers to work with other etherium competitors, like Solana, Tezos and more. And I took a closer look at them, comparing to polkadot and came to next conclusions:
Main feature of polkadot is that everyone could have its own blockchain (parachain) ...
