In an example embodiment, a validating peer of a plurality of validating peers in a blockchain network receives, from a non-validating peer, a request to create a root block of a blockchain. The root block includes information related to a potential computer security threat. The validating peer creates the root block with a root block pending validation status. The validating peer shares, with other validating peers of the plurality of validating peers, a notification of the root block with the root block pending validation status to provide an indication of the information. The validating peer determines whether the information is authentic. If the information is determined to be authentic, the validating peer changes the root block pending validation status to a root block authenticated validation status and shares, with the other validating peers, a notification of the root block authenticated validation status to indicate that the information is authentic.
