Blockchain is a database and software system that is in the early stages of revolutionizing the internet and online transactions.
The internet made global communications and transactions inexpensive and accessible to most. However, the internet is not secure enough. Which is why, in spite of great security improvements, major security breaches and hacking scandals are regularly in the news.
Blockchain upends the existing database model: In addition to greatly improving security, it makes transactions so transparent that any tampering is readily observed and rendered invalid.
It’s not an iterative improvement. It’s a massive leap forward that is in the early phase of transforming local and global commerce.
It’s capacity for good is breathtaking. But it will disrupt more businesses than ever, because it greatly reduces and/or eliminates the need for middlemen. Banking and contracts are only the beginning. The reality is companies will adapt or die.
