Sort of. It uses secret sharing so it's not based on computation power.

And I didn't see any, but if there is the capability of onboarding new members in the network, it requires bootstrapping a new chain, I think.

Onboarding new members on a drand network is fairly easy: there only needs to be a threshold of nodes doing a resharing ceremony and all nodes get new shares and new nodes can be onboarded like that. It's not handled by tlock or timevault, it's on the League of Entropy side and is how drand works. More details are in https://drand.love/docs/cryptography/
