Hey, founder/dev here! We will be fully open-source very soon. Our blockchain is forked from another which is open-source. The blockchain is a model in which there are nodes that are elected/voted in by the community. They are responsible for the validation/consensus of blocks getting produced. Whenever you post a question, an answer, or an upvote, the request goes straight from the browser to the blockchain, and your content gets stored there. That data now belongs to you, and you can earn tokens on it indefinitely.

Write performance should stay about the same even at scale because our network is capable of much higher transactions per second due to having elected nodes. Read performance will continue to be good because we have a caching layer where we store posts from the blockchain in a database and just serve from there. This technically adds a bit of centralization, but ultimately, everyone's content still belongs to themselves and not a centralized org.
