The world is going to change the way it acts: how financial institutions work, how organizations conduct business, or how governments govern. Everything is going to change, all because of blockchains. In fact, the change has already begun.
The blockchain is a digital distributed ledger of transactions which are maintained chronologically and publicly across an entire network in clusters called blocks. Bitcoin and other cryptocurrencies (like Ethereum or Ripple) are built atop this foundational technology. Think of blockchains as the new internet and the new trust protocol. If the information is available to everyone, no one needs an authority to stamp authenticity. The trust on transactions, identity, or assets comes intrinsically on a blockchain.
