This video talks about transaction fields and global parameters on PyTeal. When sending an application call to an Algorand smart contract, you may send other transactions in the same atomic group. If you application call need to access information from those other transactions, you use the transaction fields to access those information. If you need information about the state of the blockchain, you use the global parameters. Watch this video to learn how to use transaction fields and global parameters when writing PyTeal smart contracts.
