He doesn’t get it in the slightest:
Blockchain is a foundational digital technology that rivals the internet in its potential for transformation. To explain: essentially, “blocks” are segregated, vast bundles of data in permanent communication with each other so that each block knows what the content is in the rest of the chain. However, only the owner of a particular block has the digital key to access it.
So what? First, the blocks are created by “miners”, individual algorithm writers and companies throughout the world (with a dense concentration in China), who want to add a data block to the chain.
