PulseChain Bridge stores a number of Validators which need to sign off every message coming from the PulseChain. Once quorum of signatures is reached, message (e.g. withdrawal request) can be relayed to a destination contract.
Users can be censored if validators decide to not pass selected messages between chains (CRITICAL).
Funds can be stolen if validators relay a fake message to a destination chain to mint more tokens than there are locked on Ethereum thus preventing some existing holders from being able to bring their funds back to Ethereum (CRITICAL).
Funds can be stolen if validators relay a fake message to Ethereum chain allowing a user to withdraw tokens from Ethereum escrow when equivalent amount of tokens has not been deposited and burned on destination chain (CRITICAL).
Funds can be frozen if validators don't relay messages between chains.
