The [`block_prologue`](https://github.com/movementlabsxyz/aptos-core/blob/aa45303216be96ea30d361ab7eb2e95fb08c2dcb/aptos-move/framework/aptos-framework/sources/block.move#L224) and its DKG variant `block_prologue_ext` both primarily call to [`block_prologue_common`](https://github.com/movementlabsxyz/aptos-core/blob/aa45303216be96ea30d361ab7eb2e95fb08c2dcb/aptos-move/framework/aptos-framework/sources/block.move#L155).

All transactions now call one of the [`*_script_prologue`](https://github.com/movementlabsxyz/aptos-core/blob/aa45303216be96ea30d361ab7eb2e95fb08c2dcb/aptos-move/aptos-vm/src/aptos_vm.rs#L2244) functions, which in turn call [`prologue_common`](https://github.com/movementlabsxyz/aptos-core/blob/aa45303216be96ea30d361ab7eb2e95fb08c2dcb/aptos-move/framework/aptos-framework/sources/transaction_validation.move#L74).

There are distinct epilogues for executing blocks and transactions within blocks in the Aptos Framework.

The Block Epilogue does not map neatly to a single function. Importantly, it can trigger `reconfiguration::reconfigure`(https://github.com/movementlabsxyz/aptos-core/blob/aa45303216be96ea30d361ab7eb2e95fb08c2dcb/aptos-move/framework/aptos-framework/sources/reconfiguration.move#L107) which calls the following coin invoking methods:

114
114
-`transaction_fee::process_collected_fees` which does not invoke any minting capabilities.
115
115
-`stake::on_new_epoch` which mints rewards for validators in `distribute_rewards`[https://github.com/movementlabsxyz/aptos-core/blob/aa45303216be96ea30d361ab7eb2e95fb08c2dcb/aptos-move/framework/aptos-framework/sources/stake.move#L1648].

To ensure the block epilogue does not `abort` on the `mint` branch, we would need to either set the reward rate to zero or add logic to skip the minting of rewards under a given feature flag.
The transaction [`epilogue`](https://github.com/movementlabsxyz/aptos-core/blob/aa45303216be96ea30d361ab7eb2e95fb08c2dcb/aptos-move/framework/aptos-framework/sources/transaction_validation.move#L330) does make a call to `mint_and_refund` in the `mint` branch. However, this is [disabled](https://github.com/movementlabsxyz/aptos-core/blob/aa45303216be96ea30d361ab7eb2e95fb08c2dcb/aptos-move/framework/aptos-framework/sources/transaction_validation.move#L330) when the `ggp` feature flag is set.
