21st Century Learning and Teaching

A major breakthrough in cryptography may have solved one of the biggest obstacles to using blockchain technology on Wall Street: keeping transaction data private.

Known as a “zero-knowledge proof,” the new code will be included in an Oct. 17 upgrade to the ethereum blockchain, adding a level of encryption that lets trades remain private. Previously, users were able to remain anonymous but transactions were verified by allowing everyone on the network to see them.

“Zero-knowledge proofs are one of the biggest inventions in the last two decades in cryptography,” said Emin Gun Sirer, an associate professor of computer science at Cornell University. It “will allow a slew of applications we can’t even imagine right now.”

DAOs, Hacks and the Law
“The DAO” is in the midst of an epic hack due to an exploit on the originating smart contracts. Unfortunately it may seem that their own choice of legal infrastructures may force them to honor the exploit instead of the intent.
Smart contracts meet the law
While the specifics vary from land to land, the law has a broad set of parameters that are uniform. They govern the agreements made between humans and the rules which bind them.
Curiously, the DAO, in order to show it’s adherence to a certain form of “smart” contract stated that it would be fully and exclusively bound by these blockchain smart contracts.

If the blockchain frenzy and the hype surrounding it is anything to go by, blockchain is set to revolutionise everything from the way in which we make payments to the way in which we drink beer. I may have made that last bit up – but you get the idea that in and amongst the buzz there are some pretty wild predictions being made! So in this post, i thought it would be useful to take a step back from the hype and understand “what is blockchain?” If you keep coming back to this fundamental question, i think it can help you navigate and understand what use cases are feasible and which ones are not. Through these 6 awesome infographics we get a good understanding of what blockchain is:
