Abstract
An example operation may include one or more of receiving a data file with off-chain content that originated in a first security domain of a multi-domain blockchain network, verifying that the on-chain and off-chain content satisfies a cross-domain security policy between the first security domain and a second security domain within the multi-domain blockchain network with a different security policy than the first security domain, in response to verifying the on-chain and off-chain content, signing the on-chain portion of the data file with a signature of a cross-domain endorsement peer, transmitting the signed on-chain portion of the data file to an ordering service of the multi-domain blockchain network, and transmitting the off-chain portion of the data file to a cross-domain content controller in the first security domain.
