Hashes Match?

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":"Lawrence Knudsen","date":"2022-03-27","manner_of_death":"shot","armed":"gun","age":"56","gender":"M","race":"","city":"Maricopa","state":"AZ","signs_of_mental_illness":"False","threat_level":"other","flee":"","body_camera":"False","is_geocoding_exact":"True"}},"evidenceLinks":[],"locationCity":"Maricopa","locationCountry":"US","locationHasGeo":true,"locationLat":33.073,"locationLong":-111.996,"locationState":"Arizona","locationStateCode":"AZ","month":3,"source":"WashingtonPost","sourceAdditionalData":[],"sourceDatetime":1648339200,"sourceId":"7876","sourceRawData":"{\"id\":\"7876\",\"name\":\"Lawrence Knudsen\",\"date\":\"2022-03-27\",\"manner_of_death\":\"shot\",\"armed\":\"gun\",\"age\":\"56\",\"gender\":\"M\",\"race\":\"\",\"city\":\"Maricopa\",\"state\":\"AZ\",\"signs_of_mental_illness\":\"False\",\"threat_level\":\"other\",\"flee\":\"\",\"body_camera\":\"False\",\"longitude\":\"-111.996\",\"latitude\":\"33.073\",\"is_geocoding_exact\":\"True\"}","sourceRawDataFormat":"json","sourceUrl":"https://raw.githubusercontent.com/washingtonpost/data-police-shootings/master/fatal-police-shootings-data.csv","title":"Lawrence Knudsen, 56, from Maricopa, Arizona - shot on 27 March 2022","updateHistory":[],"victimAge":56,"victimArmed":"Gun","victimGender":"Male","victimName":"Lawrence Knudsen","victimRace":"Unknown","year":2022}
