Accessing the Ledger Meta: Contract Events

Ledger Meta

Approximately every 5 seconds the ledger is updated and a new ledger meta is provided: the meta is a record of everything that happened in those 5 seconds: transactions, entry changes, contract events, etc.

As opposed to the ledger which tracks a continuous state, the meta is the transition between ledgers. In our case, the meta is used specifically for accessing contract events.

Accessing Contract Events

Being pugged to Stellar Core, Zephyr has real-time speed access to the newly emitted metas meaning that for every ledger close, your program will have live access to the updated entries and especially contract events.

Those will be easily accessed by users thanks to ZephyrVM host functions. That's for what concerns live data. It is also possible to access past events by running a data catchup.
