Setup Parachain

[ltfschoen]

• Parathread auction mechanism is in the Polkadot repo.
• There is no difference between a parachain and a parathread (so far).
• Each block, a parachain will be guaranteed a slot to put their latest block head, whereas a parathread is not guaranteed that spot, but can auction for it. Once a parathread or parachain gets their slot for that block, they are indistinguishable from the code perspective
  • PR is here: Introduce Parathreads (runtime) paritytech/polkadot#341
• Notify the relay chain whether your chain is a parachain or a parathread by the way you sign up. To be a parachain, you go through the parachain candle auction process and you register your parachain. As a parathread, you place a one time deposit to be part of the "parathread pool" and then you can do bids each block.
  You can also swap between the two statuses, assuming you find someone of the opposite status to swap with
