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 and a second output different from the first output
generating first content for transmission to the blockchain;
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, 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;
determining that a transaction having the second output of the first transaction as an input has been transmitted to the blockchain by a first time; and
in response to the determination, transmitting, to the blockchain, a third transaction that transfers a third quantity of the committed first quantity of tokens to an address associated with the first node.
2. The method of claim 1 , wherein the third transaction includes a transaction parameter specifying a point in time after which the third transaction becomes eligible for transmission to the blockchain.
3. The method of claim 2 , wherein the transaction parameter specifies a point in time that is a fixed length of time after a time at which the first transaction is transmitted to the blockchain.
4. The method of claim 1 , wherein the third transaction is created and signed by the entity prior to transmission of the first transaction to the blockchain.
5. The method of claim 1 , wherein the third quantity is equal to the difference between the first quantity and the second quantity.
6. 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 .
7. A non-transitory processor-readable medium storing processor-executable instructions to participate in a process for transmitting content to a blockchain, wherein the processor-executable instructions, when executed by a processor, cause the processor to carry out the method claimed in claim 1 .
