Suppose I have a dapp that monitors transaction of some assets. The smart contract would be generating transactions and I'd get messages like "executed transaction: 7f0cb79e317e874ba74530e03dab2cdae66497925ce05637e32ae0893529886e 104 bytes 279 us"

For the UI, which is probably running with eosjs, how can I know when these transactions happen?

Is it possible to monitor certain kinds of events from the blockchain? E.g if I have a pokemon-esque game and someone posts a challenge using a smart contract action
