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":"Marcus Martin was killed after he responded to unspecified \"tactical measures,\" by firing a shotgun just after 3:15 a.m., and Officer Jeffery Archambault shot and killed him. Officers were responding to allegations of assault by Martin.","evidenceAdditional":{"type":"text","data":{"name":"Marcus Martin","age":"40","gender":"Male","race":"African-American/Black","race_with_imputations":"African-American/Black","imputation_probability":"Not imputed","address":"6000 block Alta Avenue","city":"Baltimore","state":"MD","zipcode":"21206","county":"Baltimore City","full_address":"6000 block Alta Avenue Baltimore MD 21206 Baltimore City","agency_responsible":"Baltimore Police Department","cause_of_death":null,"dispositions_exclusions":"Pending investigation","image_of_victim":"https://fatalencounters.org/wp-content/uploads/2021/08/Marcus-Martin.jpg"}},"evidenceLinks":["https://fatalencounters.org/wp-content/uploads/2021/08/Marcus-Martin.jpg","https://www.baltimoresun.com/news/crime/bs-md-ci-cr-police-shooting-updated-information-20210811-t4cfmjeemregnamndtnewmxo64-story.html"],"locationCity":"Baltimore","locationCountry":"US","locationHasGeo":true,"locationLat":39.3512541,"locationLong":-76.5463621,"locationState":"Maryland","locationStateCode":"MD","month":8,"source":"FatalEncountersDotOrg","sourceAdditionalData":[],"sourceDatetime":1628467200,"sourceId":"30745","sourceRawData":"{\"Unique ID\":\"30745\",\"Name\":\"Marcus Martin\",\"Age\":\"40\",\"Gender\":\"Male\",\"Race\":\"African-American/Black\",\"Race with imputations\":\"African-American/Black\",\"Imputation probability\":\"Not imputed\",\"URL of image (PLS NO HOTLINKS)\":\"https://fatalencounters.org/wp-content/uploads/2021/08/Marcus-Martin.jpg\",\"Date of injury resulting in death (month/day/year)\":\"08/09/2021\",\"Location of injury (address)\":\"6000 block Alta Avenue\",\"Location of death (city)\":\"Baltimore\",\"State\":\"MD\",\"Location of death (zip code)\":\"21206\",\"Location of death (county)\":\"Baltimore City\",\"Full Address\":\"6000 block Alta Avenue Baltimore MD 21206 Baltimore City\",\"Latitude\":\"39.3512541\",\"Longitude\":\"-76.5463621\",\"Agency or agencies involved\":\"Baltimore Police Department\",\"Highest level of force\":\"Gunshot\",\"UID Temporary\":\"\",\"Name Temporary\":\"\",\"Armed/Unarmed\":\"\",\"Alleged weapon\":\"\",\"Aggressive physical movement\":\"\",\"Fleeing/Not fleeing\":\"\",\"Description Temp\":\"\",\"URL Temp\":\"\",\"Brief description\":\"Marcus Martin was killed after he responded to unspecified \\\"tactical measures,\\\" by firing a shotgun just after 3:15 a.m., and Officer Jeffery Archambault shot and killed him.
