I'm the Founder of an app for events and ticketing and am considering having it built on the blockchain as a distributed app (Dapp). What are any drawbacks to building a startup on the blockchain now? Would it be better to wait until there are more established financial/governmental structures in place to handle blockchain startups?
This biggest drawback in my opinion is that DApps cost money to use in the form of gas if on the Etherium network. That could potentially add friction to building a user base for your app. If the nature of the application mitigates this, then there are some advantages to building a DApp (store of value, the fact that the app will not be reliant on any centralized infrastructure etc)
Other potential drawbacks - Because DApps are a store of value, security is of the utmost importance. Real money can be stolen due to bugs in the code. (See the Dao hack).
Bottom line, use the best architecture to fit your use case.. That may or may not include blockchain.
You should first decide if blockchain is a good solution for your problem. From your summary I suspect it might not be the case. Tickets have expiring value, so unless you are building a platform where you need to maintain consensus (for example, of you want to allow users to trade tickets/seats), blockchain would only give you a system of records.
Is there a value for your users in proving that they attended something in the past? If the answer is "No", you probably don't need a public blockchain (and it saves you gas, too, as mentioned above).
For audit trail purposes, while you can effectively use blockchain (and it can be your private blockchain), there are other, much simpler methods.
The first question would be: What is the use case you are using that makes blockchain or Dapp use desirable? If your case for using blockchain technology is strong enough (decentralization & immutability are often primary reasons), and you think you can be first-to-market with a killer app, then it may be a worthwhile venture.
Alison, do you have a website to describe RSVP? The reason I am asking is we are looking to expand our offerings that includes events/tickets. I would like to know more about the type of events you offer. Thanks in advance.
