thank you very much Michael for this valuable course i really liked they way you explain, just one quick note in EFC20 TOKEN smart contract in transferFrom function you first added token to [_to] address then you updated(subtracted) it from [_from],(which should be otherwise) which is prone to Re-entrancy attack.

Course details
Have you wondered how blockchain can help you create applications that offer greater transparency, traceability, efficiency, and resilience while lowering your costs? This course, eighth in a series of eleven, steps through using the smart contract code you write to create a decentralized application (dApp). This dApp uses supply chain functions. Instructor Michael Solomon explains what dApps are, then covers the payment token smart contract and the supply chain smart contract that you need for this project. He goes over the functions of both smart contracts and describes how to use and implement events. Michael discusses how, in blockchain technology, every action has an owner, which makes everything that happens on the blockchain auditable. He walks you through how to ensure security in your smart contracts, then concludes with useful information on implementing minimal functionality.
