make this into some bullet points for a presentation! Blockchain Technology and Global Supply Chains

Global production and supply chain management are, by design, complex and geographically disjointed, especially in a multinational corporation's network of global supply chains. Each supply chain involves multiple companies, multiple links in the chain, and lots of resource ties between these entities and links. Given such a dynamic and multifaceted setup, the nature of globalization with trade barriers, varied policies worldwide, diverse cultural and environmental issues, and people from business and nonbusiness functions make it difficult to have a good handle on information that flows in global supply chains. It also makes it difficult to manage risk, security, and value$-$added aspects of the chain. Every company wants just$-$in$-$time information at its disposal, but not every organization in a global supply chain is willing or able to supply such information easily.

Meanwhile, many supply chain executives and corporate strategists make a compelling case that information flows in global supply chains are perhaps more critical than even the flow of products, component parts, and raw materials. Timing in production relies on information flows. In particular, traceability is becoming an urgent requirement and a fundamental differentiator in many supply chains $($e$.$g$.,$ agrifood sector, pharmaceutical and medical products, high$-$value goods$).$ Lack of information transparency in these chains prevents organizations and customers from verifying and validating the true value of the product, component part, or even raw materials. The cost involved in managing chain intermediaries, their reliability, and performance further complicate traceability in the chain. In fact, both strategic and operational issues arise from these risks and lack of transparency.

To solve some of these supply chain issues, nearly all of the world's leading companies use sophisticated enterprise resource planning $($ERP$)$ and supply chain software. Some of the systems include connected manufacturing equipment to digital shipping notices and RFID scanning. Most multinational corporations track the earliest origins of a shipment, often all the way to the recycling bin, if needed. However, even with such tracking, most large companies have only limited information on where all their shipment is at any given moment in the global supply chain even after investing heavily in their digital infrastructure. One of the core reasons for this limited information is that even as supply chains are becoming more efficient, corporations often do not have an up$-$to$-$date technology infrastructure to manage the chains. Then again, even if possible, not every organization in a global supply chain is willing or able to supply such information easily.

Enter blockchain technology! Blockchain technology refers to a distributed electronic ledger that has the capacity to record a variety of transaction types, such as those that occur within a supply chain. The ledger is distributed across a peer$-$to$-$peer network; it is duplicated and stored on multiple independent servers within a decentralized peer$-$to$-$peer network. This distributed ledger can provide complete transparency to transacting parties. While any of the computers connected to the network can make changes to the ledger, they can only do so by following the rules set out in the blockchain's underlying consensus protocol $($a predetermined mathematical algorithm$)$ that requires the majority of other computers on the network to agree to a given change in the ledger. Once a consensus has been established in accordance with the algorithm's encoded rules, all the computers on the network update their copies of the ledger simultaneously. Changes cannot be made to the distributed ledger without a consensus and cannot be made $($or altered$)$ retroactively without agreement as defined in the consensus protocol. Any attempt to do so will be automatically rejected by the network. The term "blockchain" is derived from the fact that transactions are bundled together into "blocks" of data that are then "chained" together by encrypted "locks." These "locks" are a product of the consensus protocol and encryption is used to inhibit fraud. The goal is to produce a ledger that contains an immutable shared record of the truth that cannot be manipulated in real time or in retrospect. The key point here is that the integrity of the ledger is guaranteed by mathematical rules, cryptography, and its decentralized nature

Another important aspect of a blockchain system is what are known as smart contracts. Smart contracts are automated mathematical rules stored in a blockchain. These rules state that an event $($e$.$g$.,$ transaction$)$ cannot take place until certain prespecified actions have occurred and have been accepted by the network $($e$.$g$.,$ a payment will not proceed until X and Y have occurred$).$ For example, a company and its supplier could write a smart contract that would trigger the automatic release o
