Exchange hosting server

A computer-implemented method performed on a data processing apparatus comprising:

• receiving, from a first computing device at a second computing device, a request for transfer conditions for a transfer of resources;
• determining that there is no exchange participant of a hosted exchange at the second computing device that can complete the transfer of resources;
• determining an exchange participant that can complete a destination sub-transfer of the transfer of resources;
• generating a partial set of transfer conditions in response to the request for transfer conditions, the partial set of transfer conditions comprising an incomplete path comprising an incompletely specified first sub-transfer and a second sub-transfer, wherein the incompletely specified first sub-transfer comprises a transfer of a first resource type from a first resource pool to a second resource pool on a third computing device wherein the first resource pool is not identified, and wherein the second sub-transfer comprises the transfer of a second resource type from a third resource pool to a fourth resource pool on the second computing device, and wherein the second resource pool and third resource pool are controlled by the exchange participant and the second resource pool is identified in exchange participant data for the exchange participant;
• and
• sending the partial set of transfer conditions to the third computing device.

A computer-implemented method performed on a data processing apparatus comprising:

• receiving, from a first computing device at a second computing device, a request for transfer conditions for a transfer of resources and a partial set of transfer conditions comprising an incomplete path;
• determining an exchange participant of a hosted exchange at the second computing device that can complete the transfer of resources;
• generating a set of transfer conditions in response to the request for transfer conditions and partial set of transfer conditions, the set of transfer conditions comprising a path comprising a first sub-transfer, a second sub-transfer, and a third sub-transfer, wherein the first sub-transfer comprises a transfer of a first resource type from a first resource pool to a second resource pool on the first computing device and is specified in the incomplete path, wherein the second sub-transfer comprises the transfer of a second resource type from a third resource pool to a fourth resource pool on the second computing device, wherein the third resource pool is specified in an incompletely specified sub-transfer of the incomplete path, and wherein the third sub-transfer comprises a transfer of a third resource type from a fifth resource pool to a sixth resource pool on a third computing device wherein the fifth resource pool is specified in the request for transfer conditions, and wherein the third resource pool and sixth resource pool are controlled by the exchange participant;
• and
• sending the set of transfer conditions to the third computing device.

A system comprising:

• one or more computers and one or more storage devices storing instructions which are operable, when executed by the one or more computers, to cause the one or more computers to perform operations comprising:
• receiving, from a first computing device at a second computing device, a request for transfer conditions for a transfer of resources;
• determining an exchange participant of a hosted exchange at the second computing device that can complete the transfer of resources;
• generating a set of transfer conditions in response to the request for transfer conditions, the set of transfer conditions comprising a path comprising a first sub-transfer and a second sub-transfer, wherein the first sub-transfer comprises a transfer of a first resource type from a first resource pool to a second resource pool on the first computing device, and wherein the second sub-transfer comprises the transfer of a second resource type from a third resource pool to a fourth resource pool on the second computing device, and wherein the second resource pool and third resource pool are controlled by the exchange participant;
• and
• sending the set of transfer conditions to the first computing device.
