A microfork occurs when a Block Producer begins to produce blocks with the same block height as a block that was recently produced. This is often the result of high latency between producing nodes, which may occur from time to time. Since this is a small divergence in the flow of blocks on the blockchain, this is known as a microfork. There is very little cause for concern, and microforks should be almost undetectable to the average user. Watch our video explanation.
