Which model describes how data is written to a blockchain?

Striving – and achieving – supply chain excellence is a top priority for the company, which takes a global approach to procuring and sourcing its products, and reports 99.98 percent order accuracy in North America. DATAVERSITY ® had an opportunity to learn from Scott Mooney, Vice President, Distribution Operations for McKesson Pharmaceuticals, about the company’s Data Management for the DATAVERSITY (DV) : How does the use of GS1 supply chain standards impact McKesson? Mooney: We have found that GS1 standards are best suited for product marking/identification and to exchange DSCSA data, regardless of data structure such as GS1 Standards are tremendously valuable to our operations because they make our systems truly interoperable with that of our trading partners. They make our business processes more efficient to be able to meet the requirements set forth in DSCSA. Not only are we confident in our ability to meet or exceed DSCSA deadlines, but we can also leverage standards beyond just compliance to be a proactive and communicative supply chain partner. DV: Can you provide more detail on how McKesson manages DSCSA requirements? Mooney: McKesson is a full-service wholesale distributor and also has packaging and a generics manufacturing business, as well as being a solution provider for our customers. As such we are both an author of DSCSA data as well as a recipient of DSCSA data, and we serve to assist our customers in storing and managing their DSCSA data through our solut...

(6 pages) Blockchain is one of the major tech stories of the past decade. Everyone seems to be talking about it—but beneath the surface chatter there’s not always a clear understanding of what blockchain is or how it works. Despite its reputation for impenetrability, the basic idea behind blockchain is pretty simple. And it has major potential to Blockchain is a technology that enables the secure sharing of information. Data, obviously, is stored in a database. Transactions are recorded in an account book called a ledger. A blockchain is a type of distributed database or ledger—one of today’s Blockchain allows for the permanent, immutable, and transparent recording of data and transactions. This, in turn, makes it possible to exchange anything that has value, whether that is a physical item or something less tangible. A blockchain has Next, a blockchain is a digital log or database of transactions, meaning it happens fully online. And finally, a blockchain is a database that is shared across a public or private network. One of the most well-known public blockchain networks is the Learn more about McKinsey’s How does blockchain work? A deeper dive may help in understanding When data on a blockchain is accessed or altered, the record is stored in a “block” alongside the records of other transactions. Stored transactions are encrypted via unique, unchangeable hashes, such as those created with the SHA-256 algorithm. New data blocks don’t overwrite old ones; they are appended ...

• By: • • April 25, 2022 • Which Model Defines How Data Is Written To A Blockchain? Data is not stored in a traditional database on a Blockchain. Data in a blockchain can’t be tampered with. This is possible because of the append-only nature of the blockchain database. What this basically means is that after a transaction data is stored in a blockchain (as a block), that data can’t be edited or altered. As a result, all such transactions are shielded from getting corrupted. But wait! The rabbit hole is much deeper. There are many aspects to data storage on a blockchain. Smart Contracts Smart contract is another aspect of writing data to a blockchain. These are digital contracts stored on blockchains and automatically executed on the realization of predetermined terms and conditions. They can be used to automate agreement executions or workflows. All participants will get instant updates in real-time. They can also automate a future workflow process and trigger the desired action when the desired conditions are met. Smart contracts work based on simple statements written into code on a blockchain. When a set of predetermined conditions are satisfied, a network of computers swings into action to execute the transactions when predetermined needs are met and verified. The blockchain is updated on every completed action, making the action irreversible and transparent. However, only those with authorized access can view the results. Many stipulations may be incorporated within a...
