Concert tickets are an absolutely pointless application of a blockchain. The concert venue is an unavoidable central authority. You don't need to melt the arctic for a fully decentralized trust-nobody system that merely manages a database of a single ultimate authority that can't be removed from the equation. This problem can be solved with a REST API and it will have the exact same amount of (de)centralization and trust.
