Great stuff. I just have a few comments. In addition to these I'd also like to see either a few paragraphs or placeholders linked to follow-up tickets for sBTC recovery mode, which is a consensus level change, and the liveness ratio (it's part of consensus right?).

| If 2/3rd of the Stackers agree that the block is valid, they sign off on this block, at which point this block is added to the blockchain and becomes the new tip. All blocks have to build on top of it. Thus, unless the network is compromised, Stacks guarantees a single block (soft) finality from the *Nakamoto* release. This makes sBTC fulfillment a much more dependable and reliable process for users of the protocol. | ||

| Moreover, because Stacks no longer forks, sBTC can be treated like any other SIP-10 token and mined and used quickly on Stacks without the need to wait for Bitcoin confirmations. |

This is still possible even in the presence of forks, although the absence of forks makes withdrawals much faster because we can fulfill withdrawals directly.

| sBTC is also not really affected by short lived Bitcoin forks as the protocol already ensures that there are sufficient number of Bitcoin block confirmations before being fulfilled that it is almost guaranteed that they will never be orphaned by the time they are picked up by a block producer set. As such, sBTC is not speculatively instantiated or destroyed and can only materialize or dematerialize once its deposit and withdraw transactions are sufficiently confirmed, and is completely independent of Stacks recovery mechanism from soft Bitcoin forks. |

This is not really true afaik. Stacks forks with bitcoin as I understand it, so any sBTC operation in a short lived fork on Bitcoin would materialize on the equivalent Stacks fork. Therefore, Stacks doesn't even have to wait for many block confirmations to materialize an sBTC deposit. As soon as it's mined on Bitcoin, the sBTC can (and will) be minted on Stacks. And as soon as sBTC is burned on Stacks it is safe to initiate a withdrawal fulfillment on Bitcoin.
