Different communication and software protocols may be used by different blockchain networks. Cross-chain communication is provided via a software bridge configured to enable specific operations. An event request may be sent from a first blockchain network to a second blockchain network. The event request may be processed using a first protocol of the first network to provide a first output. An offer of equivalent processing provided by the second network may be verified by: processing the event request using a second protocol of the second network to provide a second output, and confirming that the second output matches the offer of equivalent processing. A processing equivalence of the event request may be established between the first network and the second network based on the first output of the event request processed using the first protocol and the second output of the event request processed using the second protocol.
