Blockchain-based systems and methods for communicating, storing and processing data over a blockchain network
A computer-implemented method for transmitting and/or submitting digital content such as feedback for an entity to a blockchain is disclosed. This may be, for example, the Bitcoin blockchain. The method, which is implemented at a first node, includes: submitting, to the blockchain, a first transaction for committing a first quantity of tokens to transfer to a second node associated with the entity, the first transaction having a first output; generating a first content for submission to the blockchain; and submitting, to the blockchain, a second transaction that returns a second quantity of the committed first quantity of tokens to an address associated with the first node, the second transaction having the first output of the first transaction as an input, wherein the first content is used to unlock the first output of the first transaction.
1. A computer-implemented method for transmitting data to a blockchain, the method comprising:
transmitting, to the blockchain, a first transaction for committing a first quantity of tokens to transfer to a second node associated with an entity, the first transaction having a first output;
generating first content for transmission to the blockchain; and
transmitting, to the blockchain, a second transaction that returns a second quantity of the committed first quantity of tokens to an address associated with a first node, wherein the second transaction has the first output of the first transaction as an input, and an unlocking script that includes the first content and is used to unlock the first output of the first transaction,
wherein a locking script of the first output of the first transaction includes a set of permitted content entries and wherein the first content corresponds to one of the permitted content entries.
2. The method of claim 1 , wherein the set of permitted content entries includes hashes of one or more permitted content values.
3. The method of claim 2 , further comprising:
receiving an indication of the one or more permitted content values,
wherein generating the first content comprises selecting one of the permitted content values.
4. The method of claim 1 , wherein the unlocking script of the second transaction includes a signature corresponding to a public key associated with the first node.
5. The method of claim 2 , wherein the one or more permitted content values comprise one or more discrete ratings.
6. The method of claim 1 , wherein metadata for the second transaction includes an identifier associated with a product offered by the entity.
7. A computing device to participate in a process for transmitting content for an entity to a blockchain, the computing device configured to carry out the method claimed in claim 1 .
8. A computing device to participate in a process for transmitting content for an entity to a blockchain, the computing device configured to carry out the method claimed in claim 2 .
9. A computing device to participate in a process for transmitting content for an entity to a blockchain, the computing device configured to carry out the method claimed in claim 3 .
10. A computing device to participate in a process for transmitting content for an entity to a blockchain, the computing device configured to carry out the method claimed in claim 4 .
11. A non-transitory computer-readable medium storing computer-executable instructions to participate in a process for transmitting content to a blockchain, wherein the computer-executable instructions, when executed by a processor, cause the processor to carry out the method claimed in claim 1 .
12. A non-transitory computer-readable medium storing computer-executable instructions to participate in a process for transmitting content to a blockchain, wherein the computer-executable instructions, when executed by a processor, cause the processor to carry out the method claimed in claim 2 .
13. A non-transitory computer-readable medium storing computer-executable instructions to participate in a process for transmitting content to a blockchain, wherein the computer-executable instructions, when executed by a processor, cause the processor to carry out the method claimed in claim 3 .
14. A non-transitory computer-readable medium storing computer-executable instructions to participate in a process for transmitting content to a blockchain, wherein the computer-executable instructions, when executed by a processor, cause the processor to carry out the method claimed in claim 4 .
