Synced blocks
This is a new term for some people, so here's a brief description. A blockchain is an unchangeable, public ledger that shows all the contract activity on the network. Your Sia needs to catch up to everyone else's Sia so that it's on the same page, and understands things like how much money you have to spend and who is hosting your data.
Sia creates trustless, automatic-paying contracts with hosts to store your data. The reason it can do this, and drive prices down, is because the blockchain that governs Sia pre-loads these contracts with funds and ensures that hosts only get paid when they have fulfilled their end of the deal. Their deal, of course, is to store your data. All of this happens because of the blockchain.
