When you hear the word blockchain what comes to mind? You may associate it with Bitcoin, but blockchain is much more than just Bitcoin. A blockchain at its core is a distributed ledger with an immutable or unchangeable record of transactions or assets. So anywhere there’s a need to keep track of something, you might soon find blockchain. Blockchain rapidly is growing from its cryptocurrency roots to finding its place in government and industries like healthcare, real estate and transportation.

The U.S. Postal Service (USPS) has filed a patent in blockchain technology, and it is looking into increasing efficiency, security and establishing an identity verification system or Digital Identity on blockchain. A 26-page report issued by the USPS Office of Inspector General stated, “Identity services are one of the biggest areas of opportunity in the blockchain community, and the Postal Service, as a highly trusted government agency, would be well-suited for a role in identity verification.” The USPS report continued, “Customers could use these verified identities to log in to secure websites, notarize documents or participate in smart contracts.”

Leafy greens may not be the first thing you think of when you think of blockchain, but in the wake of an outbreak of E.

Walmart will require farmers and food suppliers to have these blockchain-enabled systems in place by the end of 2019.
