Starknet is building a ZK rollup, batching transactions using their sequencer and sending proofs of these batches to the Bitcoin chain. From a security perspective, using BitVM for trust-minimized bridging is better than standard multisig-based solutions as it requires only one honest operator.
Starknet still relies on a centralized sequencer, which is common among rollups, because Bitcoin and Ethereum chains aren't performant enough for sequencing. Having a centralized sequencer reduces system security and censorship resistance, so this is an area for improvement.
