Privacy preserving validation and commit architecture
A method of scheduling and validating a multiple-participant process, the method including: submitting, by a submitting node associated with a participant in the multiple-participant process, a proposed transaction by sending a cryptographically-protected message to one or more recipient nodes, wherein the cryptographically-protected message includes at least an unencrypted submessage readable by an external node and a cryptographically-protected submessage to preserve privacy from at least the external node; determining, by the external node, an order of the proposed transaction relative to other transactions; by way of at least some of the recipient nodes, validating the cryptographically-protected message; receiving a confirmation of validity of the cryptographically-protected message from at least some of the recipient nodes; finalizing the proposed transaction, as a confirmed transaction, based on receiving one or more confirmations from at least some of the recipient nodes that satisfy a confirmation condition; and writing the confirmed transaction to a distributed ledger according to the order determined by the external node.
1. A method for a multi-domain transaction process, the method comprising:
splitting, by an initiator node connected to a first domain and a second domain, a transaction into sub-transactions including a first sub-transaction and a second sub-transaction, wherein:
the first sub-transaction includes a first resource request and a first payload for a first participant, and
the second sub-transaction includes a second resource request and a second payload for a second participant;
submitting, by the initiator node, the first resource request to a first external node of the first domain, wherein the first resource request specifies a first amount of resources required by the first participant for a first time period;
submitting, by the initiator node, the second resource request to a second external node of the second domain, wherein the second resource request specifies a second amount of resources required by the second participant for a second time period;
determining, by the initiator node after a third time period, whether the first resource request was accepted or rejected by the first participant and whether the second resource request was accepted or rejected by the second participant; and
based upon determining whether the first resource request and the second resource request were accepted or rejected by the first participant and the second participant respectively, (i) transmitting, by the initiator node, the first payload to the first external node and the second payload to the second external node, or (ii) aborting the multi-domain transaction process.
2. The method of claim 1 , further comprising aborting the multi-domain process upon determining:
the first resource request was rejected by the first participant within the third time period, or
the second resource request was rejected by the second participant within the third time period.
3. The method of claim 1 , further comprising:
aborting the multi-domain transaction process upon determining no responses to the first resource request and/or second resource request were received within the third time period.
4. The method of claim 1 , further comprising:
receiving, prior to determining whether the first resource request was accepted or rejected, a first response to the first resource request from the first external node; and
receiving, prior to determining whether the second resource request was accepted or rejected, a second response to the second resource request from the second external node.
5. The method of claim 4 , wherein determining whether the first resource request was accepted or rejected includes determining whether the first response to the first resource request was received within the third time period, and
wherein determining whether the second resource request was accepted or rejected includes determining whether the second response to the second resource request was received within the third time period.
6. The method of claim 5 , further comprising aborting the multi-domain transaction process upon determining the first response and/or the second response was received after the third time period.
7. The method of claim 4 , further comprising aborting the multi-domain transaction process upon determining the first response rejects the first resource request and/or the second response rejects the second resource request.
8. The method of claim 4 , further comprising determining:
the first response accepts the first resource request; and
the second response accepts the second resource request.
9. The method of claim 8 , further comprising:
transmitting the first payload to the first external node; and
transmitting the second payload to the second external node.
10. A system connected to a first domain and a second domain comprising:
one or more processors; and
one or more memory devices storing instructions that when executed by the one or more processors, cause the one or more processors to perform operations directed to a multi-domain transaction comprising:
splitting a transaction into sub-transactions including a first sub-transaction and a second sub transaction, wherein:
the first sub-transaction includes a first resource request and a first payload for a first participant, and
the second sub-transaction includes a second resource request and a second payload for a second participant;
submitting, by the initiator node, the first resource request to a first external node of the first domain, wherein the first resource request specifies a first amount of resources required by the first participant for a first time period;
submitting, by the initiator node, the second resource request to a second external node of the second domain, wherein the second resource request specifies a second amount of resources required by the second participant for a second time period;
determining, after a third time period, whether the first resource request was accepted or rejected by the first participant and whether the second resource request was accepted or rejected by the second participant; and
based upon determining whether the first resource request and the second resource request were accepted or rejected by the first participant and the second participant respectively, transmitting the first payload to the first external node and the second payload to the second external node or aborting the multi-domain transaction.
11. The system of claim 10 , wherein the operations further comprise aborting the multi-domain transaction upon determining:
the first resource request was rejected by the first participant within the third time period, or
the second resource request was rejected by the second participant within the third time period.
12. The system of claim 10 , wherein the operations further comprise:
aborting the multi-domain transaction upon determining no responses to the first resource request and/or the second resource request were received within the third time period.
13. The system of claim 10 , wherein the operations further comprise:
receiving, prior to determining whether the first resource request was accepted or rejected, a first response to the first resource request from the first external node; and
receiving, prior to determining whether the second resource request was accepted or rejected, a second response to the second resource request from the second external node.
14. The system of claim 13 , wherein determining whether the first resource request was accepted or rejected includes determining whether the first response to the first resource request was received within the third time period, and
wherein determining whether the second resource request was accepted or rejected includes determining whether the second response to the second resource request was received within the third time period.
15. The system of claim 14 , further comprising aborting the multi-domain transaction upon determining the first response and/or the second response was received after the third time period.
16. The system of claim 13 , wherein the operations further comprise aborting the multi-domain transaction process upon determining the first response rejects the first resource request and/or the second response rejects the second resource request.
17. The system of claim 13 , wherein the operations further comprise:
the first response accepts the first resource request; and
the second response accepts the second resource request.
18. The system of claim 17 , wherein the operations further comprise:
transmitting the first payload to the first external node; and
transmitting the second payload to the second external node.
19. A non-transitory computer-readable medium storing instructions for performing a multi-domain transaction process, the instructions, when executed by one or more processors, cause the one or more processors to:
split a transaction into sub-transactions including a first sub-transaction and a second sub-transaction, wherein:
the first sub-transaction includes a first resource request and a first payload for a first participant, and
the second sub-transaction includes a second resource request and a second payload for a second participant;
submit the first resource request to a first external node of the first domain, wherein the first resource request specifies a first amount of resources required by the first participant for a first time period;
submit the second resource request to a second external node of the second domain, wherein the second resource request specifies a second amount of resources required by the second participant for a second time period;
determine, after a third time period, whether the first resource request was accepted or rejected by the first participant and whether the second resource request was accepted or rejected by the second participant; and
based upon determining whether the first resource request and the second resource request were accepted or rejected by the first participant and the second participant respectively, transmit the first payload to the first external node and the second payload to the second external node or abort a multi-domain transaction process.
20. The non-transitory computer-readable medium of claim 19 , wherein the instructions, when executed by the one or more processors, further cause the one or more processors to:
abort the multi-domain process upon determining:
a first response to the first resource request is not received within the third time period, or
a second response to the second resource request is not received within the third time period; or
