minimal_time ctxt priority pred_block_time returns the minimal time, given the predecessor block timestamp pred_block_time, after which a baker with priority priority is allowed to bake in principle, that is, assuming the block will contain enough endorsements.

check_timestamp ctxt priority pred_timestamp verifies that the timestamp is coherent with the announced baking slot.

For a given level computes who has the right to include an endorsement in the next block. The result can be stored in Alpha_context.allowed_endorsements
Check that the operation was signed by a the delegate allowed to endorse at the given slot and at the level specified by the endorsement. The slot should be the smallest among the delegate's slots.

Tezos_protocol_environment_010_PtGRANAD__Environment.Error_monad.errorTezos_protocol_environment_010_PtGRANAD__Environment.Error_monad.trace)result
Returns the baking reward calculated w.r.t a given priority p and a number e of included endorsements

Tezos_protocol_environment_010_PtGRANAD__Environment.Error_monad.errorTezos_protocol_environment_010_PtGRANAD__Environment.Error_monad.trace)result
Returns the endorsing reward calculated w.r.t a given priority.
first_baking_priorities ctxt ?max_priority contract_hash level is a list of priorities of max ?max_priority elements, where the delegate of contract_hash is allowed to bake for level. If ?max_priority is None, a sensible number of priorities is returned.
Checks if the header that would be built from the given components is valid for the given difficulty. The signature is not passed as it is does not impact the proof-of-work stamp. The stamp is checked on the hash of a block header whose signature has been zeroed-out.

Tezos_protocol_environment_010_PtGRANAD__Environment.Error_monad.errorTezos_protocol_environment_010_PtGRANAD__Environment.Error_monad.trace)result
verify if the proof of work stamp is valid

Tezos_protocol_environment_010_PtGRANAD__Environment.Error_monad.errorTezos_protocol_environment_010_PtGRANAD__Environment.Error_monad.trace)result
check if the gap between the fitness of the current context and the given block is within the protocol parameters
A block is valid only if its timestamp has a minimal delay with respect to the previous block's timestamp, and this minimal delay depends not only on the block's priority but also on the number of endorsement operations included in the block.
In Emmy+, blocks' fitness increases by one unit with each level.
In this way, Emmy+ simplifies the optimal baking strategy: The bakers used to have to choose whether to wait for more endorsements to include in their block, or to publish the block immediately, without waiting. The incentive for including more endorsements was to increase the fitness and win against unknown blocks. However, when a block was produced too late in the priority period, there was the risk that the block did not reach endorsers before the block of next priority. In Emmy+, the baker does not need to take such a decision, because the baker cannot publish a block too early.
Given a block priority and a number of endorsement slots (given by the `endorsing_power` argument), it returns the minimum time at which the next block can be baked.
