WHAT THE HECK IS BLOCKCHAIN?

Maersk Cntr LiftMaersk and IBM recently announced they are teaming up on blockchain technology, which made us wonder…what the heck is blockchain?  We found a definition that seemed to make sense.

The information held on a blockchain exists as a shared, and continually updated/reconciled, database. The blockchain database is not stored in any single location.  The records are truly public and easily verifiable.  No centralized version of this information exists for a hacker to corrupt. Hosted by millions of computers simultaneously, its data is accessible to anyone on the internet.
