receive, via the peer of the permissioned blockchain of the second blockchain network, an I owe you (IOU) message from an asset requester, the IOU message identifying an obligation between the asset requester and the asset provider for the asset on the public blockchain of the first blockchain network; accumulate the IOU message with one or more other IOU messages to create a net obligation, and store the net obligation via a netting transaction on the permissioned blockchain of the second blockchain network; determine to perform a settlement operation of the net obligation based on a block parameter which specifies a plurality of blocks to be stored on the permissioned blockchain in between settlement operations; and in response to the determination, generate a settlement transaction for settling the net obligation via the peer of the second blockchain network and transmitting the settlement transaction to a peer of the first blockchain network to perform actual transfer of the asset on the public blockchain. ### Claim 2 (depends on 1) The system of claim 1, wherein the processor is configured to generate and transmit the settlement transaction every M number of blocks stored on the public blockchain since a last settlement transaction. ### Claim 3 (depends on 1) The system of claim 1, wherein the processor is further configured to determine whether at least one of the asset requester and the asset provider are on an exclusionary list, and reject generation of the netting transaction for the permissioned blockchain network based on the check. ### Claim 4 (depends on 1) The system of claim 1, wherein the processor is configured to accumulate uncompleted asset transfer requests for the permissioned blockchain, determine a sum total of owed asset transfers for all nodes of the second blockchain network associated with one or more uncompleted asset transfer requests, and include the sum total within the netting transaction that is transmitted to the first blockchain network. ### Claim 5 (depends on 1) The system of claim 1, wherein the processor is configured to: obtain a settlement operation parameter; and in response to determining a number of blocks committed since a last settlement operation is equal to the settlement operation parameter, submit the settlement transaction to the first blockchain network. ### Claim 6 A method, comprising: receiving, by a blockchain peer of a permissioned blockchain of a second blockchain network, a request to transfer an asset on a public blockchain of a first blockchain network from an asset provider; receiving, by the blockchain peer of the permissioned blockchain of the second blockchain network, an I owe you (IOU) message from an asset requester, the IOU message identifying an obligation between the asset requester and the asset provider for the asset on the public blockchain of the first blockchain network; accumulating the IOU message with one or more other IOU messages to create a net obligation, and store the net obligation via a netting transaction on the permissioned blockchain of the second blockchain network; determining to perform a settlement operation of the net obligation based on a block parameter which specifies a plurality of blocks to be stored on the permissioned blockchain in between settlement operations; and in response to the determination, generating a settlement transaction for settling the net obligation via the blockchain peer of the second blockchain network and transmitting the settlement transaction to a peer of the first blockchain network to perform actual transfer of the asset on the public blockchain. ### Claim 7 (depends on 6) The method of claim 6, wherein the generating and the transmitting comprises generating and transmitting the settlement transaction every M number of blocks stored on the public blockchain since a last settlement transaction. ### Claim 8 (depends on 6) The method of claim 6, further comprising: determining whether at least one of the asset requestor and the asset provider are on an exclusionary list, and rejecting generation of the netting transaction for the permissioned blockchain network based on the check. ### Claim 9 (depends on 6) The method of claim 6, wherein the accumulating comprises accumulating uncompleted asset transfer requests for the permissioned blockchain network, determining a sum total of owed asset transfers for all nodes of the second blockchain network associated with one or more uncompleted asset transfer requests, and including the sum total within the netting transaction that is transmitted to the first blockchain network. ### Claim 10 (depends on 6) The method of claim 6, further comprising: obtaining a settlement operation parameter from the second blockchain network; and in response to determining that a number of blocks committed since a last settlement operation is equal to the settlement operation parameter, submitting the settlement transaction to the first blockchain network. ### Claim 11 A non-transitory computer readable medium comprising instructions, that when read by a processor, cause the processor to perform a method comprising: receiving, by a blockchain peer of a permissioned blockchain of a second blockchain network, a request to transfer an asset on a public blockchain of a first blockchain network from an asset provider; receiving, by the blockchain peer of the permissioned blockchain of the second blockchain network, an I owe you (IOU) message from an asset requester, the IOU message identifying an obligation between the asset requester and the asset provider for the asset on the public blockchain of the first blockchain network; accumulating the IOU message with one or more other IOU messages to create a net obligation, and store the net obligation via a netting transaction on the permissioned blockchain of the second blockchain network; determining to perform a settlement operation of the net obligation based on a block parameter which specifies a plurality of blocks to be stored on the permissioned blockchain in between settlement operations; and in response to the determination, generating a settlement transaction for settling the net obligation via the blockchain peer of the second blockchain network and transmitting the settlement transaction to a peer of the first blockchain network to perform actual transfer of the asset on the public blockchain. ### Claim 12 (depends on 11) The non-transitory computer readable medium of claim 11, wherein the generating and the transmitting comprises generating and transmitting the settlement transaction every M number of blocks stored on the public blockchain since a last settlement transaction. ### Claim 13 (depends on 11) The non-transitory computer readable medium of claim 11, wherein the accumulating comprises accumulating uncompleted asset transfer requests for the second blockchain network, determining a sum total of owed asset transfers for all nodes of the second blockchain network associated with one or more uncompleted asset transfer requests, and including the sum total within the netting transaction that is transmitted to the first blockchain network. ### Claim 14 (depends on 11) The non-transitory computer readable medium of claim 11, wherein the method further comprises: obtaining a settlement operation parameter from the second blockchain network; and in response to determining that a number of blocks committed since a last settlement operation is equal to the settlement operation parameter, submitting the settlement transaction to the first blockchain network.
