Polkadot Cross-Chain Bridge
Polkadot Cross-Chain Bridge enables asset and data transfer between Polkadot's parent chain and parachains.
Trustlessness by LI.FI
• Relies on the Relay Chain’s (Polkadot’s parent chain) shared security model and the target Parachain's validators.
• There needs to be at least one honest collator (full nodes of Parachains and the Relay Chain) for sending/receiving messages between Parachains. It is theoretically possible for collators to censor messages.
