Huge Win for Internet Privacy in Canada: R. v. Spencer

A landmark Supreme Court decision came down last Friday: R. v. Spencer.

This case takes Canada away from the past regime where police could request subscriber information corresponding to an IP without a warrant. In earlier lower court decisions judges have relied on ISP terms of service to say that users have no reasonable expectation of privacy. The legal theory was that the contracts users enter into allowed ISPs to disclose information to police so it was permitted. The Supreme Court unanimously rejected this regime and declared such searches "presumptively unreasonable":

BitPay (Stripe for Bitcoin): $1m+ Daily Volume

BitPay (a less feature-rich Stripe for Bitcoin) claims to be processing more than $1 million USD in transactions per day.

It's hard to get a sense of how large the world of Bitcoin is, and especially hard to get a handle on the amount used for commerce vs. speculation. BitPay is one of the main merchant processing companies so this statistic is one worth paying attention to.

Decentralized Bitcoin Exchanges

I've written a blog post on the Decentral Tumblr blog: "Decentralized Bitcoin Exchanges: A Solution with Three Big Challenges". This blog post explains what a decentralized Bitcoin exchange is, why Bitcoin industry people are keen on the idea and what the implementation challenges are.

I recommend reading the article if you're curious about where exchanges (e.g. CAVirtEx) are headed. Many people in the industry think that decentralized exchanges are what people will be using in a few years. The first person to create one that works will make a big splash.

Ontario's 50 Top Appellate Lawyers

I've written a series of programs that process and extract the names of counsel from Ontario Court of Appeal judgements. I've analysed 8077 decisions and extracted 12,000 lawyer-case pairs (some decisions have multiple counsel).

Lavabit's Role in the Snowden Saga

Edward Snowden's email provider, Lavabit, shut down their company rather than let the US government spy on their customers:

It would take a lot of moral strength to agree to shut down something you've built up over years of work in order to protect your customers from spying. It would have been very easy for them to allow secret spying (like Google, Facebook, etc.) but instead they stand out as the one company I'm aware of that refused to provide "lawful access" by the US government.
