Note

Medium Risk
A multi-minor jump in the core Chia client dependency can change pool protocol, RPC, and consensus behavior without any compensating code changes in this repo.

Overview
Pins chia-blockchain from 2.4.4 to 2.7.4 in both requirements.txt and setup.py so installs and the package’s install_requires stay aligned.

There are no application or pool logic changes in this PR—only the version constraint. Reviewers should treat this as adopting upstream 2.7.4 (protocol, consensus, wallet/RPC, and farmer-related changes per the release notes) and validate the reference pool against a 2.7.4 node/wallet stack.
