2. Currently there's no detail how "sequencer" (party who create block) is chosen[2].
It will probably be centralized/federated at first, then decentralize ln due course.
The documentation already state SatoshiVM currnetly is the only one who create block. I was referring about how decentralized one works.
My hypothesis, it will be Proof Of Stake. Because these " decentralized networks" outside of Bitcoin generally issue "tokens", I believe SatoshiVM will issue one of its own, then have those sequencers "stake" their "tokens", and their users delegate their own "tokens".
I will not open a debate on why Proof Of Stake is flawed. That deserves its own topic.
3. While we can "move" BTC to SatoshiVM by ourselves[3], i didn't find how to "move" BTC from SatoshiVM to mainnet which is a bit concerning.
It will probably through an off-chain Bitcoin to on-chain Bitcoin market of some sort?
¯\_(ツ)_/¯
Using exchange/market works, but it should be done by interesting with SatoshiVM directly.
We're merely looking at the test-net. I believe there will be a two-way bridge for their main-net.
