 1. The initial version of Stacks (released early 2021) had a separate security budget which changed to following 100% Bitcoin hashpower with the Nakamoto release. There is old material and blog posts floating around that still talk about the initial Stacks version. The old materials will likely get updated with time.
 2. According to the Ethereum definition of L2s a user should be able to withdraw their base-layer assets purely by doing a L1 transaction and relying only on L1 security (this is true for Lightning for example). This definition does not apply cleanly to Bitcoin L2s because assets are not defined at Bitcoin L1 but are defined in L2s instead. The only asset where this matters is the pegged BTC asset from Bitcoin L1, given all other assets are native to L2s anyway. In the upcoming Stacks release, users can withdraw their BTC by sending just a Bitcoin L1 transaction but Bitcoin L1 cannot validate that complex transaction and a majority of peg-out signers will need to sign on the peg-out request. In an ideal world Bitcoin miners can validate such transactions but that would require a change to Bitcoin L1. Therefore, Stacks design optimizes for a method that is decentralized and can be deployed without any changes to Bitcoin L1. If in the future it is possible to make changes to Bitcoin L1 then Stacks layer security can benefit from that as well.
-3. Bitcoin community members are generally skeptical of claims and on a look out for people making any false marketing claims. This is generally a healthy thing for the Bitcoin ecosystem and builds up the immune system. Some such community members might be skeptical about Stacks as a Bitcoin layer or L2 until they fully read the technical details and reasoning. There is a good [Twitter thread](https://twitter.com/lopp/status/1623756872976158722?s=20) about his topic as well.

 Why don't we use the term 'sidechain' for Stacks then? Sidechains in Bitcoin typically have a different security budget from Bitcoin L1, typically as a subset of Bitcoin miners who participate in the sidechain (they don't follow 100% Bitcoin finality), their consensus runs on the sidechain (vs running on Bitcoin L1), and they don't publish their data/hashes on Bitcoin L1. The Stacks layer does not fit that definition cleanly given the consensus runs on Bitcoin L1, it follows Bitcoin finality, and publishes data/hashes on L1.

 The only way to remove the token is to build Stacks as a federated network like Liquid. In a federation the pre-selected group of companies control the mining and block production and a pre-selected group of companies need to be trusted for peg-out transactions. 
 
-Stacks developers wanted to design an open and permissionless system. The only way to have a decentralized mining process is through incentives. As mentioned above, his is how Bitcoin works as well, where newly minted BTC are used as incentives to mine new blocks and anyone in the world can decide to become a miner. Anyone with BTC can mine the Stacks L2 chain, it is open and permissionless.

 Similarly, the way sBTC is designed is that the group of signers is open and permissionless (unlike a federation). These signers have economic incentives to correctly follow the protocol for peg-out requests. In a federation, users need to blindly trust the pre-set federation members to get their BTC out of the federation and back on Bitcoin L1. Stacks developers wanted to have an open, permissionless, and decentralized way to move BTC from Bitcoin L1 to Stacks L2 and back. This is made possible through economic incentives i.e., need for a token.
