This ensures that the mempool cannot be spammed with garbage transactions. * Verify that the sender of the transaction has enough funds to cover for the `fees`. When the end-user generates a transaction, they must indicate 2 of the 3 following parameters (the third one being implicit): `fees`, `gas` and `gas-prices`. This signals how much they are willing to pay for nodes to execute their transaction. The provided `gas` value is stored in a parameter called `GasWanted` for later use. * Set `newCtx.GasMeter` to 0, with a limit of `GasWanted`. **This step is crucial**, as it not only makes sure the transaction cannot consume infinite gas, but also that `ctx.GasMeter` is reset in-between each transaction (`ctx` is set to `newCtx` after `anteHandler` is run, and the `anteHandler` is run each time a transactions executes).
