Systems and methods for communication, storage and processing of data provided by an entity over a blockchain network
A computer-implemented method for submitting feedback for an entity to a blockchain is disclosed. The method, which is implemented at one of a plurality of participating nodes, includes: obtaining a first key, the first key being one of a fixed set of keys distributed to participating nodes that are eligible to submit feedback for the entity; generating first feedback (r j ) of the entity for submission to the blockchain; encrypting the first feedback (r j ) using at least the first key; and submitting the encrypted first feedback to a mixing service, the mixing service being configured to generate a mixed transaction based on the encrypted first feedback and at least one other encrypted feedback submission from one or more eligible participating nodes.
1. A computer-implemented method comprising:
joining, as a node participating in a blockchain network, a feedback submission process as a reviewing node;
generating feedback configured to be submitted by an entity to a blockchain of the blockchain network;
encrypting the feedback with at least a key of a set of keys, the set of keys distributed among eligible reviewers; and
submitting the encrypted feedback to a mixing service.
2. The computer-implemented method of claim 1 , wherein the encrypted feedback is formed as one of three elements forming a two-of-three multi-signature script.
3. The computer-implemented method of claim 1 , wherein the feedback is further encrypted with a public key of the entity.
4. The computer-implemented method of claim 1 , wherein joining the feedback submission process identifies two or more additional nodes as participating.
5. The computer-implemented method of claim 1 , further comprising encrypting a secret, the secret generated based on a public key of the entity and the set of keys distributed among eligible reviewers.
6. The computer-implemented method of claim 5 , wherein the encrypted secret is made accessible to the entity.
7. The computer-implemented method of claim 2 , wherein submitting the encrypted feedback to a mixing service includes providing a portion of a joint input with at least one other eligible reviewer of the eligible reviewers.
8. A system, comprising:
a node participating on a blockchain network, the node comprising a processor and a non-transitory memory coupled to the processor, the non-transitory memory having stored thereon executable instructions that when executed by the processor, cause the node to:
join a feedback submission process as a reviewing node;
generate feedback configured to be submitted by an entity to a blockchain of the blockchain network;
encrypt the generated feedback with at least a key share of a set of key shares distributed to one or more eligible reviewers; and
transmit the encrypted feedback to a service;
the service, wherein the service is configured to:
delink the feedback from an address identifying the reviewing node; and
provide the delinked feedback to the entity; and
the entity, wherein the entity is configured to submit the feedback to the blockchain.
9. The system of claim 8 , wherein the instructions further cause the service to generate a joint transaction based on the encrypted feedback to be recorded on the blockchain.
10. The system of claim 9 , wherein the joint transaction is generated based on an encrypted data submission from the one or more eligible reviewers.
11. The system of claim 8 , wherein the entity is a third-party further configured to authenticate that the feedback is from an eligible reviewer.
12. The system of claim 11 , wherein the entity is further configured to identify a candidate for which the feedback is intended.
13. The system of claim 12 , wherein the entity identifies the candidate among a plurality of candidates based on a quantity of tokens submitted with the encrypted feedback, the quantity corresponding to the candidate.
14. The system of claim 8 , wherein the entity is further configured to verify that the feedback was generated by an eligible reviewer based on the key share.
15. The system of claim 8 , wherein the entity is further configured to verify that the feedback was generated by an eligible reviewer based on the key share.
16. A computer-implemented method, comprising:
generating, by a node participating on a blockchain network, a first transaction of a commitment channel as a reviewer comprising feedback for an entity, the feedback being encrypted by at least a key share of a set of key shares distributed to one or more eligible reviewers, wherein the first transaction defines a first quantity of tokens to transfer to the entity;
generating a second transaction to transfer a second quantity of tokens to the reviewer based on one or more conditions; and
generating a third transaction to transfer the first quantity of tokens from the reviewer to the entity, wherein execution of the third transaction requires an indication of the feedback being decrypted and a signature of the entity.
17. The computer-implemented method of claim 16 , wherein the first transaction is a multi-signature script.
18. The computer-implemented method of claim 17 , wherein the multi-signature script is a two-of-three multi-signature script requiring a signature of the reviewer and another signature of the entity.
19. The computer-implemented method of claim 17 , wherein the multi-signature script is a two-of-three multi-signature script requiring an indication of decrypted feedback and a signature of the entity.
20. The computer-implemented method of claim 17 , wherein the feedback is able to be submitted to a blockchain of the blockchain network after a defined time has expired.
