Specifically, whenever a new Observation is generated, the system will record the related information of the Observation (such as data, events, etc.) and its corresponding ObservationTimestamp in a new block. This block will contain a hash value pointing to  the previous block to ensure the order and connection between blocks. As new blocks are continuously added to the chain, the Observations and their corresponding ObservationTimestamps are preserved in the blockchain in chronological order."}]}],"pr":"c69516879a0c1917dfd4eca23e325b19ce0364d92f350cdc8e6f3c200079d823"}
