Three startups are getting ready to launch one of the most ambitious and important cryptocurrency experiments since the creation of bitcoin itself. Called Lightning, the project aims to build a fast, scalable, and cryptographically secure payment network layered on top of the existing bitcoin network.

Essentially, Lightning aims to solve the big problem that has loomed over bitcoin in recent years: Satoshi Nakamoto's design for bitcoin is comically unscalable. It requires every full node in bitcoin's peer-to-peer network to receive and store a copy of every transaction ever made on the network.

Initially, that design was vital to achieving Nakamoto's vision of a fully decentralized payment network. But as Purdue computer scientist Pedro Moreno-Sanchez told Ars, it creates a big challenge as the network becomes more popular. "We have reached a point where it's not suitable any more to keep growing," he said.

EU Anti-Piracy Agreement Has Little Effect on Advertising, Research Finds

One of the best ways to beat piracy, according to many copyright industry groups, is to “follow the money.” This is the reason why advertising agencies are encouraged to cut their deals with pirate sites. One such agreement was facilitated by the European Commission, but according to new research, its effects are minimal.

In recent years various copyright holder groups have adopted a “follow-the-money” approach in the hope of cutting off funding to so-called pirate sites.

Thus far this has resulted in some notable developments. In the UK, hundreds of advertising agencies began banning pirate sites in 2014 and similar initiatives have popped up elsewhere too.

One of the more prominent plans was orchestrated by the European Commission. In October 2016, this resulted in a voluntary self-regulation agreement signed by leading EU advertising organizations, which promised to reduce ad placement on pirate sites. The question is, how effective is this agreement?

To find out, researchers from European universities in Munich, Copenhagen, and Lisbon, conducted an extensive study. They collected data on the prevalence of ads from various advertisers on hundreds of pirate sites. The data were collected on several occasions, both before and after the agreement.

The findings are published in the article “Follow The Money: Online Piracy and Self-Regulation in the Advertising Industry.” Christian Peukert, one of the authors, informs TF that the latest version of the working paper was published last month and is currently under review at an academic journal.

The results show that the effects of the anti-piracy agreement are fairly minimal. On a whole, there is no significant change in the volume of piracy sites that ad agencies serve. Only when looking at the larger ad-networks in isolation, a downward trend is visible.

“Our results suggests that the presence of advertising services on piracy websites does not change significantly, at least not on average,” the researchers write in their paper.

“Once we allow for heterogeneity in terms of size, we show that more popular advertising services, i.e. those that are overall more diffused on the Internet, reduce their presence on piracy websites significantly more.”

When larger advertising companies are given more weight in the analysis, the average effect equates to a 17% drop in pirate site connections.

That larger companies are more likely to comply with the agreement can be explained by a variety of reasons. They could simply be more aware of the agreement, or they feel more pressure to take appropriate steps in response.

Interestingly, there are also advertising companies that began advertising on pirate sites after the agreement was signed.

“We further provide some evidence that ad services that were not active in the piracy market before the self-regulation agreement increase their presence on piracy websites afterwards,” the researchers write.

This may have been partly triggered by site owners looking for alternatives, or advertising companies looking for new opportunities. However, the effect is not statistically significant, which means that people shouldn’t read into it too much.

Overall, however, the researchers conclude that the voluntary agreement only had a relatively small impact on the EU advertising as a whole, and that there’s room for improvement.

“These results raise concerns about the overall effectiveness of the self-regulation effort with respect to reducing incentives for publishers to supply unlicensed content,” they write.

The EU agreement coincided with a series of similar agreements which, according to this data, had little effect on EU advertisers either over the researched timespan. And by looking at the average pirate site today, it becomes instantly clear that there are still plenty advertisers who are willing to work with these sites.

A taste for the beautiful: How evolution shapes attraction

A new book provides stories of sex and beauty, from the lab and from the field.

“Why All the Fuss about Sex?” wonders Michael Ryan. He wonders enough to make it the title of the first chapter of his new book, A Taste for the Beautiful. One would be forgiven for thinking it would be a short chapter—consisting of the single word “duh”—but Ryan is a zoologist who studies evolution and animal behavior. So he has a slightly different take.

“I have a unique perspective to offer on these issues,” he writes, “as I have spent the past 40 years studying the sexual behavior of a tiny, bumpy frog in Central America.”

It’s not that he has a fetish; it’s that he uses these túngara frogs—along with bowerbirds, howler monkeys, fireflies, peacock spiders, collared lizards, corn borer moths, hairy caterpillars, surf perches, and bee orchids—to demonstrate how beauty, and the appreciation of it, may have evolved in animals. Like us.

Blizzard Targets Fan-Created ‘World of Warcraft’ Legacy Server

Blizzard Entertainment is taking a stand against a popular World of Warcraft legacy server. The fan-operated project allows gamers to experience how the game was played over a decade ago and to revive old battles. Blizzard, however, sees this as copyright infringement and has asked GitHub to pull the site’s code offline.

Over the years video game developer Blizzard Entertainment has published many popular game titles, including World of Warcraft (WoW).

First released in 2004, the multiplayer online role-playing game has been a massive success. It holds the record for the most popular MMORPG in history, with over 100 million subscribers.

While the current game looks entirely different from its first release, there are many nostalgic gamers who still enjoy the earlier editions. Unfortunately, however, they can’t play them. At least not legally.

The only option WoW fans have is to go to unauthorized fan projects which recreate the early gaming experience, such as Light’s Hope.

“We are what’s known as a ‘Legacy Server’ project for World of Warcraft, which seeks to emulate the experience of playing the game in its earliest iterations, including advancing through early expansions,” the project explains.

“If you’ve ever wanted to see what World of Warcraft was like back in 2004 then this is the place to be. Our goal is to maintain the same feel and structure as the realms back then while maintaining an open platform for development and operation.”

In recent years the project has captured the hearts of tens of thousands of die-hard WoW fans. At the time of writing, the most popular realm has more than 6,000 people playing from all over the world. Blizzard, however, is less excited.

The company has asked the developer platform GitHub to remove the code repository published by Light’s Hope. Blizzard’s notice targets several SQL databases stating that the layout and structure is nearly identical to the early WoW databases.

“The LightsHope spell table has identical layout and typically identical field names as the table from early WoW. We use database tables to represent game data, like spells, in WoW,” Blizzard writes.

“In our code, we use .sql files to represent the data layout of each table […]. MaNGOS, the platform off of which Light’s Hope appears to be built, uses a similar structure. The LightsHope spell_template table matches almost exactly the layout and field names of early WoW client database tables.”

This takedown notice had some effect, as people now see a “repository unavailable due to DMCA takedown” message when they access it in their browser.

While this may slow down development temporarily, it appears that the server itself is still running just fine. There were some downtime reports earlier this week, but it’s unknown whether that was related.

In addition to the GitHub repository, the official Twitter account was also suspended recently.

TorrentFreak contacted both Blizzard and Light’s Hope earlier this week for a comment on the situation. At the time of publication, we haven’t heard back.

Blizzard’s takedown notice comes just weeks after several organizations and gaming fans asked the US Copyright Office to make a DMCA circumvention exemption for “abandoned” games, including older versions of popular MMORPGs.

While it’s possible that such an exemption is granted in the future, it’s unlikely to apply to the public at large. The more likely scenario is that it would permit libraries, researchers, and museums to operate servers for these abandoned games.
