1. A computer-implemented method for cross-chain communication, the method comprising:
receiving a transaction including a message and an aggregate signature, the aggregate signature generated based on signature keys corresponding to one or more validators of a source blockchain that signed the message;
identifying the one or more validators of the source blockchain based on the aggregate signature;
determining, based on a shared registry, whether the one or more validators comprise a stake threshold percentage of validators of the source blockchain;
validating the transaction based on the one or more validators comprising the stake threshold percentage of validators; and
transmitting a receipt message to the source blockchain indicating a successful delivery of the message.
