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":"Matthew Blaylock","date":"2021-03-29","manner_of_death":"shot","armed":"gun","age":"38","gender":"M","race":"B","city":"Los Angeles","state":"CA","signs_of_mental_illness":"False","threat_level":"other","flee":"Foot","body_camera":"False","is_geocoding_exact":"True"}},"evidenceLinks":[],"locationCity":"Los Angeles","locationCountry":"US","locationHasGeo":true,"locationLat":34.051,"locationLong":-118.264,"locationState":"California","locationStateCode":"CA","month":3,"source":"WashingtonPost","sourceAdditionalData":[],"sourceDatetime":1616976000,"sourceId":"6728","sourceRawData":"{\"id\":\"6728\",\"name\":\"Matthew Blaylock\",\"date\":\"2021-03-29\",\"manner_of_death\":\"shot\",\"armed\":\"gun\",\"age\":\"38\",\"gender\":\"M\",\"race\":\"B\",\"city\":\"Los Angeles\",\"state\":\"CA\",\"signs_of_mental_illness\":\"False\",\"threat_level\":\"other\",\"flee\":\"Foot\",\"body_camera\":\"False\",\"longitude\":\"-118.264\",\"latitude\":\"34.051\",\"is_geocoding_exact\":\"True\"}","sourceRawDataFormat":"json","sourceUrl":"https://raw.githubusercontent.com/washingtonpost/data-police-shootings/master/fatal-police-shootings-data.csv","title":"Matthew Blaylock, 38, from Los Angeles, California - shot on 29 March 2021","updateHistory":[],"victimAge":38,"victimArmed":"Gun","victimGender":"Male","victimName":"Matthew Blaylock","victimRace":"Black/African American","year":2021}
