Credit Card Sized Case Bitcoin Wallet Launches at TechCrunch Disrupt NY

Rochester-based Bitcoin startup Case has launched its hardware bitcoin wallet on-stage at TechCrunch Disrupt NY. The standalone device, which is the approximate size of a credit card, is said to provide uncompromising security and ease-of-use for Bitcoin buyers, sellers and users.

Case CEO Melanie Shapiro stated:

“Case represents an evolution for bitcoin users who buy, sell and use bitcoin (…) Since bitcoin is used just like cash, it is imperative to incorporate multi-signature security with greater simplicity and ease-of-use to ensure widespread consumer adoption. We’ve achieved both of these with our bitcoin wallet.”

Gavin Andresen Explains why he thinks Increasing the Block Size Limit is Urgent

Following his earlier proposal to increase the block size limit to 20 MB, Bitcoin Foundation Chief Scientist and Core developer Gavin Andresen published a blog post explaining why he believes such a change is urgent. According to Andresen, not raising the block size limit will soon lead to clocking of the Bitcoin network, which would deter people from using Bitcoin.


“If the number of transactions waiting gets large enough, the end result will be an over-saturated network, busy doing nothing productive. I don’t think that is likely– it is more likely people just stop using Bitcoin because transaction confirmation becomes increasingly unreliable.”

Adopting the Chain: How Tesla Could Protect its Website and its Cars

Following a hack of Tesla's website, Mike Ward in an op-ed for Cointelegraph suggests the company should opt for a blockchain based Domain Name System. And not just that. While Tesla's at it, it might as well secure its cars through blockchain technology as well!


“The blockchain is, in fact, a terrific place to store records related to the automobiles, precisely because of its tamper-proof nature. If Tesla were to run their own blockchain, with only approved nodes being able to mine blocks (publish transactions) they could house warranty and purchase information, ownership and leasing data, maintenance history, accident details and much more on-chain — all nicely timestamped and replicated across the network in a fashion that would be both tamper-resistant and convenient.”
