-Block height of the burnchain at which the stacks-node will self-terminate. Used during the testnet phases for various testing cycles.
+Maximum amount (in Satoshis) of "burn commitment" to broadcast for the next block's leader election.

-#### burnchain_op_tx_fee (optional)
+#### satoshis_per_byte (optional)
 
-Transaction fee per burnchain operation.
+Amount (in Satoshis) per [virtual byte](https://en.bitcoin.it/wiki/Weight_units). This is used to compute the transaction fees.
 
 Example:
 
 ```toml
-burnchain_op_tx_fee = 5500
+satoshis_per_byte = 50
 ```
 
-#### burn_fee_cap (optional)
-
-Max burn fee for a transaction.

-Example:

-```toml
-burn_fee_cap = 30000
-```
+So total transaction cost would be `(estimated_tx_size * satoshis_per_byte) + burn_fee_cap`.
