Blockchain: A New Approach to Secure Pharma Supply Chains

Managing pharmaceutical supply chains isn't easy. Old methods struggle with transparency and trust. So, let's talk about a new solution: blockchain. It's like a digital ledger that keeps everyone honest. It promises to solve security issues like authentication and data tracking. First, all involved parties get a unique ID. This is done using something called EdDSA. Next, smart contracts handle the movement of pharma products. These contracts make sure data stays true. Tests show this system fights off impersonation and sneaky collusion attacks. But how well does it work? Researchers checked performance with tests like gas usage, speed, and cost. Compared to older methods, blockchain looked pretty good. Remember, every supply chain has its challenges. Blockchain might not fix everything, but it's a start. It's important to think about how we can use it better.
