Yes, the idea behind a blockchain is a merkle tree of events, metadata and salt that hashes with a predetermined number of 0's (the difficulty) as a prefix.
If you wanted to make your event stream more tamper-proof you could also introduce a merkle tree-like row which hashes the current event, the previous hash and a secret key. Any tampering of the data would need this key and would need to recompute future events.
It's still not perfect because with the key this is easy to do.
