Until recently, the prevailing method for blockchain interoperability has been to send messages between chains. Across Cofounder Hart Lambur joined our Variant Builder Day on interoperability to talk about why it’s all but impossible to do that quickly, cheaply, and securely. Blockchains, he says, aren’t about moving bytes, like TCP/IP—they’re about moving value. And that requires a new approach. Watch Hart explain why crosschain intent architecture is better than messaging for blockchain’s interoperability needs.
