CMDS's drones provide convenience to users, from product delivery to emergency transportation, medicine, and transplant organ transportation. The method of cryptocurrency mining is to start cryptocurrency mining when a GPU is installed inside a drone and is being transported (operated).
CommercialDronesCoin (#157-306) contract sets array length with a user-controlled value:
- lockInfo[_to].push(LockInfo(_releaseTime,_value)) (#296-298)
CommercialDronesCoin (#157-306) contract sets array length with a user-controlled value:
- lockInfo[_holder].push(LockInfo(_releaseTime,_amount)) (#271-273)
Do not allow array lengths to be set directly set; instead, opt to add values as needed. Otherwise, thoroughly review the contract to ensure a user-controlled variable cannot reach an array length assignment.

Pragma version0.5.8 (#9) allows old versions
solc-0.5.8 is not recommended for deployment
Deploy with any of the following Solidity versions: 0.5.16 - 0.5.17, 0.6.11 - 0.6.12, 0.7.5 - 0.7.6 Use a simple pragma version that allows any of these versions. Consider using the latest version of Solidity for testing.

Dangerous comparisons:

Dangerous comparisons:
- lockInfo[_holder][i].releaseTime <= now (#245)
Avoid relying on block.timestamp.
