> With this in mind, we chose to assign seven designated Block Producers for Ultra’s blockchain.

This does not sound truly distributed. Like you might as well not use Blockchain if it's not distributed.

Decentralization is really a spectrum. We have a set of block producers that we've vetted and have worked closely with to set up the infrastructure for our network. They are external companies (Ubisoft is one of them). The code that runs on the network gets vetted by them and only goes into production after they sign a multisig and allow it.

It's not thousands of anonymous nodes, but it is also not a single entity that controls everything.

We intend to build out a more decentralized pattern with more complex governance as things mature. It's a software project and as you all well know, you can't launch your ideal at the start. You launch what you can and you improve as you go. Decentralization is that way, too.

Git uses a kind of blockchain and is often centralized rather than distributed.

Pedantic but fine. I'll revise to "why use a trustless distributed ledger if you are going to only allow 7 validators. Might as well just use MySQL with an API.".
