Distributed database structures for anonymous information exchange
Provided herein are database structures, systems, and methods for an anonymous, information exchange platform. The information exchange platform described herein may comprise blockchain structures, decentralized networks, peer-to-peer technology, cryptographic techniques, and/or a combination thereof. Past and present actors associated with a topic of information (e.g., a product) may flexibly exchange information on the information exchange platform by implementing question and answer protocols.
1 . A system for distributed information exchange between multiple parties while preserving an anonymity among the multiple parties, the system comprising:
a decentralized blockchain network maintained by a plurality of computer nodes for storing a plurality of manifests related to an object, wherein one or more blocks of the decentralized blockchain network are validated by one or more of the plurality of computer nodes,
wherein at least one manifest from the plurality of manifests stored in the decentralized blockchain network comprises one or more topic and commitment (TC) pairs each of which comprising a topic of information about the object and a commitment to verifiable information on the topic, wherein the verifiable information is used to generate or verify an answer to a question related to the corresponding topic and wherein the answer is not pre-stored in the decentralized blockchain network;
one or more processors, individually or collectively, programmed to:
(a) receive a question about the object from a user device,
(b) parse the question and the plurality of manifests stored in the decentralized blockchain network to identify a TC pair from the one or more TC pairs associated with the query by filtering one or more topics of the one or more TC pairs, and
(c) upon identifying the TC pair from the one or more TC pairs, provide an answer to the question, wherein the answer is generated using or is verified using the commitment of the TC pair.
2 . The system of claim 1 , wherein the commitment comprises a numeric value.
3 . The system of claim 1 , wherein the plurality of manifests further comprise one or more question and answer (QA) pairs each of which comprising a pair of a predefined question and the corresponding answer.
4 . The system of claim 3 , wherein the one or more QA pairs are encrypted.
5 . The system of claim 1 , wherein the at least one manifest further comprises an encrypted and anonymous identity of a creator of the manifest.
6 . The system of claim 5 , wherein a real identity of the creator is not published on the decentralized blockchain network.
7 . The system of claim 6 , wherein the real identity of the creator is stored in a private registry.
8 . The system of claim 6 , wherein the real identity of the creator is encrypted and recorded on the at least one manifest.
9 . The system of claim 5 , wherein the question and answer are exchanged between the user device and a device associated with the creator via an intermediate node.
10 . The system of claim 1 , wherein the answer is validated using one or more of tracing, mass-balance systems, and tokenized certification.
11 . A computer-implemented method for distributed information exchange between multiple parties while preserving an anonymity among the multiple parties, the method comprising:
(a) receiving a question about an object from a user device, wherein a plurality of manifests related to the object are stored in a decentralized blockchain network maintained by a plurality of computer nodes, wherein one or more blocks of the decentralized blockchain network are validated by one or more of the plurality of computer nodes, and wherein at least one manifest from the plurality of manifests stored in the decentralized blockchain network comprises one or more topic and commitment (TC) pairs each of which comprising a topic of information about the object and a commitment to verifiable information on the topic, wherein the verifiable information is used to generate or verify an answer to a question related to the corresponding topic and wherein the answer is not pre-stored in the decentralized blockchain network;
(b) parsing the question and the plurality of manifests stored in the decentralized blockchain network to identify a TC pair from the one or more TC pairs associated with the query by filtering one or more topics of the one or more TC pairs;
(c) upon identifying the TC pair from the one or more TC pairs, providing an answer to the question, wherein the answer is generated using or is verified using the commitment of the TC pair.
12 . The computer-implemented method of claim 11 , wherein the commitment comprises a numeric value.
13 . The computer-implemented method of claim 11 , wherein the plurality of manifests further comprise one or more question and answer (QA) pairs each of which comprising a pair of a predefined question and a corresponding answer.
14 . The computer-implemented method of claim 13 , wherein the one or more QA pairs are encrypted.
15 . The computer-implemented method of claim 11 , wherein the at least one manifest further comprises an encrypted and anonymous identity of a creator of the manifest.
16 . The computer-implemented method of claim 15 , wherein a real identity of the creator is not published on the decentralized blockchain network.
17 . The computer-implemented method of claim 16 , wherein the real identity of the creator is stored in a private registry.
18 . The computer-implemented method of claim 16 , wherein the real identity of the creator is encrypted and recorded on the at least one manifest.
19 . The computer-implemented method of claim 11 , wherein the question and answer are exchanged between the user device and a device associated with the creator via an intermediate node.
20 . The computer-implemented method of claim 11 , further comprising validating the answer using one or more of tracing, mass-balance systems, and tokenized certification.
