Content validation using blockchain
A device may receive content data from a content provider, the content data including: data identifying content, and data for verifying that the content has not changed. The device may access a blockchain associated with the content data, the blockchain including validation information specifying instructions for validating the content. In addition, the device may perform, based on the validation information, validation of the content to determine a measure of confidence that the content is accurate and store results of the validation in the blockchain as a transaction. Based on the validation results, the device may perform an action.

a second weight being assigned to another accuracy parameter associated with the content,
the first weight having a greater effect on a final accuracy score than the second weight,
the scores being weighted to produce the final accuracy score,
the final accuracy score being compared to a threshold to determine the level of accuracy;
determine whether the content is accurate based on the validation information;
store results of the determination in the blockchain, the results being stored in the blockchain as a transaction;
perform an action based on the results; and
provide to a content provider device associated with the content provider, data that causes display of a validation indicator with the content, the validation indicator being based on the validation results.
8. The non-transitory computer-readable medium of claim 7 , where the one or more instructions, that cause the one or more processor devices to determine whether the content is accurate based on the validation information, cause the one or more processor devices to:
evaluate at least one validation parameter,
each of the at least one validation parameter indicating whether at least a portion of the content is accurate.
9. The non-transitory computer-readable medium of claim 8 , where the at least one validation parameter includes at least one of:
a first value indicating a measure of confidence that quotes included in the content are accurate;
a second value indicating a measure of confidence that a title associated with the content matches a meaning associated with the content;
a third value indicating a measure of confidence that the content provider is a provider of valid content;
a fourth value indicating a peer consensus score that indicates a degree to which peers of the content provider are associated with peer content related to the content;
a fifth value indicating a measure of confidence that facts presented in the content are accurate;
a sixth value indicating a measure of quality associated with a grammar of the content; or
a seventh value indicating a measure of quality associated with a tone of the content.
10. The non-transitory computer-readable medium of claim 8 , where the one or more instructions, that cause the one or more processor devices to determine whether the content is accurate based on the validation information, cause the one or more processor devices to:

determine whether the content is accurate based on the evaluation score.
11. The non-transitory computer-readable medium of claim 10 , where:
each of the at least one validation parameter is associated with a weight; and
the one or more instructions, that cause the one or more processor devices to generate the evaluation score based on the at least one validation parameter, cause the one or more processor devices to:
generate the evaluation score based on the weight for each of the at least one validation parameter.
