One of the hottest topics in cybersecurity circles is the enterprise blockchain. This is the same technology that underpins cryptocurrencies like Bitcoin. Simply defined, blockchain is a list of transactions or contracts shared with peers and locked down by some clever cryptography. Beyond Bitcoin, it can ensure the integrity of supply chains, manage contracts, or even as serve as a platform for financial transactions.  

Its popularity in the cryptocurrency space, use of cryptography, and distributed nature prove to supporters that the blockchain is the solution to many of our current cybersecurity problems. Akamai Technologies, for example, is currently building a blockchain-powered network for online payments. "Blockchain in and of itself is a security technology," says Andy Champagne, VP and CTO of Akamai Labs. "It is really grounded in security principles."
