How is the comparison calculated?

The hash stored in the database is used as the identifier for this report, and can be seen in the URL. The hash from the Mainchain Tx is the hash sent to and stored on Mainchain. Finally, the "generated hash" is generated each time this page is loaded, using the same data used for the hash submitted to Mainchain.

Raw data used to generate the hash, using the Node.js crypto.createHash('sha256') algorithm: {"content":"","evidenceAdditional":{"type":"text","data":{"name":"Demetrius Deshawn Roberts","date":"2021-10-04","manner_of_death":"shot","armed":"gun","age":"21","gender":"M","race":"","city":"Las Vegas","state":"NV","signs_of_mental_illness":"False","threat_level":"attack","flee":"Foot","body_camera":"False","is_geocoding_exact":"True"}},"evidenceLinks":[],"locationCity":"Las Vegas","locationCountry":"US","locationHasGeo":true,"locationLat":36.137,"locationLong":-115.199,"locationState":"Nevada","locationStateCode":"NV","month":10,"source":"WashingtonPost","sourceAdditionalData":[],"sourceDatetime":1633305600,"sourceId":"7228","sourceRawData":"{\"id\":\"7228\",\"name\":\"Demetrius Deshawn Roberts\",\"date\":\"2021-10-04\",\"manner_of_death\":\"shot\",\"armed\":\"gun\",\"age\":\"21\",\"gender\":\"M\",\"race\":\"\",\"city\":\"Las Vegas\",\"state\":\"NV\",\"signs_of_mental_illness\":\"False\",\"threat_level\":\"attack\",\"flee\":\"Foot\",\"body_camera\":\"False\",\"longitude\":\"-115.199\",\"latitude\":\"36.137\",\"is_geocoding_exact\":\"True\"}","sourceRawDataFormat":"json","sourceUrl":"https://raw.githubusercontent.com/washingtonpost/data-police-shootings/master/fatal-police-shootings-data.csv","title":"Demetrius Deshawn Roberts, 21, from Las Vegas, Nevada - shot on 4 October 2021","updateHistory":[],"victimAge":21,"victimArmed":"Gun","victimGender":"Male","victimName":"Demetrius Deshawn Roberts","victimRace":"Unknown","year":2021}
