WalkthroughThis PR applies formatting and import reordering across the codebase while adding timestamp validation to block acceptance in the blockchain. The changes enforce that new blocks must have timestamps greater than or equal to the previous block and within 60 seconds of the current system time. Changes

In `@minichain.egg-info/dependency_links.txt`:
- Line 1: The repository is tracking generated packaging metadata (egg-info)
which should be untracked; remove the committed egg-info artifacts (e.g., the
dependency_links file) from version control, add the pattern *.egg-info/ to
.gitignore to prevent future commits, and untrack existing files (stop tracking
cached files) before committing the change so stale packaging metadata is not
stored in the repo.
In `@minichain.egg-info/PKG-INFO`:
- Around line 1-8: The committed generated metadata (minichain.egg-info/ and
files like PKG-INFO) should be removed and ignored; delete the generated
artifact from the repo and prevent future commits by adding minichain.egg-info/
to .gitignore, run git rm -r --cached minichain.egg-info (or remove the folder
and commit the deletion), and commit the updated .gitignore so the packaging
step still generates these files locally but they no longer appear in source
control.
In `@minichain.egg-info/SOURCES.txt`:
- Around line 1-27: The repo currently tracks the autogenerated metadata
directory minichain.egg-info which should be ignored; update the repository
.gitignore (in the Python section) to add the egg-info pattern (e.g., add
*.egg-info/ or minichain.egg-info/) so that the minichain.egg-info/ directory is
not committed, then remove the tracked directory from git history with git rm
--cached if already committed.
In `@minichain.egg-info/top_level.txt`:
- Around line 1-3: The package metadata is shipping the test package because
package discovery is including "tests"; open the setup configuration where
find_packages or setuptools.setup is called and change package discovery to
exclude tests (e.g., call find_packages with exclude=["tests", "tests.*"] or
otherwise remove "tests" from the packages list) so the top_level.txt no longer
lists "tests" in the distributed metadata.
In `@minichain/mempool.py`:
- Around line 56-63: Flatten the nested checks by combining the `if txs:` and
the inner comparison into one condition so you only evaluate the comparison when
`txs` is truthy; update the block that assigns `best_tx`/`best_sender` (the one
referencing variables txs, best_tx, best_sender, sender, best_tx.timestamp,
best_tx.nonce) to use a single if statement like `if txs and (best_tx is None or
(txs[0].timestamp, sender, txs[0].nonce) < (best_tx.timestamp, best_sender,
best_tx.nonce)):` and keep the existing assignments to `best_tx = txs[0]` and
`best_sender = sender`.
In `@reproduce_timestamp_bug.py`:
- Around line 46-48: The test constructs future_block with
previous_hash=past_block.hash which makes it fail due to bad linkage when
past_block is rejected; change the test to link future_block to the current
chain tip instead (use the chain's tip/hash accessor or the latest block
variable instead of past_block.hash) so the block is rejected specifically for
the future timestamp; update the call that creates future_block (Block(...
previous_hash=...)) to reference the chain tip (e.g., chain[-1].hash or
get_chain_tip().hash) while keeping timestamp=9999999999999 and transactions=[]
unchanged.
