1. Can sidechains mine blocks faster than the main chain?
Yes, sidechains can potentially mine blocks faster than the main chain. They can have different consensus rules and block intervals, depending on the specific design of the sidechain.

2. Can participants in a sidechain unilaterally withdraw, or does the bundle need to be done by sidechain miners, or the sidechain owner?
In most drivechain proposals, participants can initiate a withdrawal, but the withdrawal must be processed by miners in a specific withdrawal period. This helps to secure the funds and prevent double-spending across chains.

3. Can multiple withdraw bundles be done from a sidechain concurrently, or does it need to wait the 3-6 months' worth of blocks for success or failure?
Most drivechain proposals involve a withdrawal waiting period to ensure security and consensus. Concurrent withdrawal bundles would generally have to wait for the predetermined period for success or failure.

4. Can multiple sidechains be having withdraw bundles at the same time?
Yes, multiple sidechains can operate withdrawal processes concurrently. They are independent of each other.

5. How much blockspace is required for blind merge mining all 256 slots assuming maximal sidechains?
This depends on the specific implementation and the blocksize of the sidechains. More extensive use of sidechains would, of course, require more blockspace.

6. Can a sidechain have its own set of up to 256 side chains branching off of it?
Technically, a sidechain could have its own sidechains. However, this would complicate the security and operation of the network and may not be practical in all scenarios.

7. How feasible is atomic swaps between these sidechains?
Atomic swaps between sidechains could be implemented, but it would require specific support and might introduce complexities. In the scenario you mentioned, it would likely require a withdrawal and then a new peg-in, with the associated time delay.

8. If there is no POW on the side chain itself, how are blockspace limits and fees to be handled, and how is tx spam in a sidechain addressed?
Sidechains can have their own consensus mechanisms, fee structures, and spam controls. Without PoW, a sidechain might use another consensus mechanism or rely on the main chain's PoW for security.

9. How can drivechains be decentralized and permissionless to avoid miner control on creation?
Decentralization in drivechains can be a complex issue. By design, miners play a significant role in the security and operation of drivechains. Various proposals and ongoing research aim to balance decentralization, security, and functionality in drivechain implementations.
