If you work in finance or own any bitcoin, you likely already know about blockchain technology. But for those in neither category, here’s a quick overview of a year’s worth of news about blockchains, databases that essentially make records more verifiable and permanent.

Important developments: blockchain’s effect on mobile payments, trade finance, and augmented and virtual reality. 

The more surprising themes and developments: some countries see blockchain technology as a way to cut down on voting fraud, and others, like Australia, are starting to incorporate blockchain into peer-to-peer solar power exchanges.

Google publicly broke one of the major algorithms in web encryption, called SHA-1 (a hashing function). The company’s researchers showed that with enough computing power — roughly 110 years of computing from a single GPU for just one of the phases — you can produce a collision, effectively breaking the algorithm. We’ve known this was possible for a while, but nobody has done it, in part because of the possible fallout.
The good news is, almost no one is still using SHA-1, so you don’t need to rush out and install any patches. But today’s announcement is still a major power play from Google, with real implications for web security overall.

WHAT DO HASH FUNCTIONS ACTUALLY DO?
SHA-1 is a hashing function, which produces a digital fingerprint from a given file. That lets you verify a file’s integrity without exposing the entire file, simply by checking the hash.

Banks, Online Stores, Bitcoin, & Cryptocurrency
Banks & online stores use the hash functions to secure transactions.
Cryptocurrencies like Bitcoin and Ethereum continually evolve using the latest hash functions to encrypt blocks of transactions. Bitcoin uses SHA-256 and Ethereum uses Keccak-256.

WHY DOES IT MATTER?
In practical terms, a broken hash function could be used to break HTTPS, the encryption system that now protects more than half the web. If that system breaks, it would be easy for criminals to insert malware into web traffic from a compromised ISP or other network provider.

SHOULD I BE WORRIED?
Cryptographers have been predicting a collision (that SHA-1 would be broken) like this for years. Since 2005 its vulnerability was theorized. As of January 1st, every major browser will show you a big red warning when you visit a site secured by SHA-1.

WHY DID GOOGLE DO THIS?
Dropping SHA-1 took a lot of time and effort across the industry, and not everyone was eager to do it. The result has been a running fight over how fast make the switch — with Google’s Chrome Security Team providing one of the loudest voices for a faster transition. Chrome was forcing websites away from SHA-1 as early as 2014
