 ### Stream
 
 [This example](/examples/stream/main.go) demonstrates how to stream the latest blocks and handle chain reorgs.
 The worker processes the events sequentially and relies on [BlockchainEvent_Type](/protos/coinbase/chainstorage/api.proto)
 to construct the canonical chain.
 For example, given `+1, +2, +3, -3, -2, +2', +3'` as the events, the canonical chain would be `+1, +2', +3'`.
