1. A method of managing traffic enforcement data, comprising:
generating, at a first node of a plurality of nodes, a digital evidence package related to a traffic violation;
generating, at the first node, a first package digest of the digital evidence package using a hash function;
adding the first package digest as a ledger entry in a distributed ledger, wherein the distributed ledger is synchronized across the plurality of nodes;
transmitting the digital evidence package from the first node to a second node of the plurality of nodes;
validating, at the second node, the digital evidence package received from the first node based on the first package digest added to the distributed ledger; and
modifying evidence captured by the first node that is included as part of the digital evidence package at the second node resulting in a modified digital evidence package in response to the digital evidence package being validated based on the first package digest added to the distributed ledger.
