A year ago, it implemented HTTPS encryption<\/a>, making it safer for users to click without being snooped on. Last fall, it introduced a suite of accessibility features<\/a> for its blind and visually impaired users. And Tuesday, it began accepting Verge, a privacy-focused cryptocurrency<\/p>\n Pornhub is not by any stretch the first adult site to accept cryptocurrency. Dozens already do, as do mainstream companies like Microsoft, Overstock, and Expedia. But the significance of the move lies less in the marriage of cryptocurrency and pornography than it does in the legitimization of cryptocurrency as tender generally. After all, Pornhub\u2019s not just the largest site of its kind. It\u2019s one of the largest sites on the web, period.<\/p>\n Accepting Verge does have specific value to Pornhub users, of course. Not everyone wants their credit card statement to have mature content on it, even pseudonymously. And while Verge cryptocurrency isn\u2019t an infallible cloak of invisibility, it does incorporate more anonymity tools than traditional tender.<\/p>\n \u201cIt\u2019s an anonymous additional form of payment,\u201d says Pornhub vice-president Corey Price. \u201cOffering privacy-focused payment options is something we have been looking to do for a while.\u201d<\/p>\n Pornhub's move is also notable because it chose to use Verge, a relatively unknown cryptocurrency, over cryptocurrency frontrunners like Bitcoin and Ether. It does, though, offer a few privacy-focused attributes that might make it particularly appealing to Pornhub clientele.<\/p>\n As for the specifics of how Verge offers that anonymity, it\u2019s an open source project that leverages Tor<\/a>, which hides your IP address by encrypting your traffic and bouncing it through a chain of computers around the world, and I2P, which differs in practice but offers the same broad strokes peer-to-peer routing. And using the so-called Wraith Protocol, Verge users can make either public or private blockchain transactions.<\/p>\n That last bit merits some unpacking, since that\u2019s where the real privacy promises come into play. \u201cTor and I2P are great. The problem is if you\u2019re using the public blockchain, you are leaving tracks that are completely traceable,\u201d says Matthew Green, a cryptographer at Johns Hopkins University who is also affiliated with another privacy-focused cryptocurrency, Zcash. \u201cEven if you connected through Tor, when you eventually cashed those coins in, people could track you.\u201d<\/p>\n By putting some transactions on so-called stealth addresses, rather than the public blockchain, you can ostensibly cover your tracks. But you also expose yourself to some potential pitfalls.<\/p>\n \u201cThis may superficially hide the payment on the blockchain, e.g. you can donate to Wikipedia without being publicly seen on the blockchain to be donating to them,\u201d says Emin G\u00fcn Sirer, a computer scientist at Cornell University who focuses on distributed systems. \u201cBut typically, what happens next is that the recipient groups transactions, either when organizing their wallet or when paying someone else, so the fact that you donated to Wikipedia becomes public anyway. Worse, there is nothing the sender can do to avoid this outcome.\u201d<\/p>\n Green also notes that transactions on the private blockchain require a certain level of trust. \u201cIt could work well,\u201d he says. \u201cI guess you just wouldn\u2019t know until something bad happened.\u201d<\/p>\n Pornhub, along with several other major adult sites, is owned by a Luxembourg-based company called MindGeek; its sister sites Brazzers and Nutaku will accept Verge as well, with more to follow. But both they and their customers might want to brace themselves.<\/p>\n 'Verge never offered a unique set of features not offered elsewhere.'<\/p>\n Emin G\u00fcn Sirer, Cornell University<\/p>\n Other companies, after all, have been burned by cryptocurrency before. Microsoft bowed out of bitcoin briefly in January, but reversed course a few days later. Payments startup Stripe began accepting bitcoin in 2015<\/a>, only to drop it earlier this year, citing extreme volatility. Both moves followed a huge spike<\/a> and subsequent drop, a pattern all too familiar to bitcoin observers. In December, a single bitcoin was worth nearly $20,000. Today, it\u2019s closer to $8,000.<\/p>\n \u201cBitcoin has evolved to become better-suited to being an asset than being a means of exchange,\u201d wrote<\/a> Stripe CEO Tom Karlo at the time, appending a host of reasons for its transactional decline: slow confirmation times, high fees, and that seemingly never-ending roller coaster of value.<\/p>\n Verge, too, has seen a roughly 40 percent swing over the last week. And earlier this month, a vulnerability in its code<\/a> apparently allowed an attacker to mine as many as 15 million coins, worth about $780,000, in the course of about three hours. The patch the Verge team pushed in response also appears<\/a> to have had issues of its own.<\/p>\n \u201cOther privacy coins supported stealth addresses already, and any cryptocurrency can already be operated on top of Tor,\u201d says Sirer. \u201cSo, overall, Verge never offered a unique set of features not offered elsewhere.\u201d<\/p>\n \u201cThere are inherent risks associated,\u201d says Pornhub\u2019s Price. \u201cNonetheless, we are excited to take this next step to keep current with our community\u2019s payment preferences and offer them this viable alternative.\u201d<\/p>\n And if customers take Pornhub up on the offer, that could help cryptocurrencies in general go more mainstream. \u201cTransactions with crypto are no big deal now,\u201d says Campbell Harvey, an economist at Duke University who studies blockchain technology, citing the big-name retailers who accept bitcoin.<\/p>\n The next step after offering a cryptocurrency payments system, though, is getting people to actually pay in cryptocurrency. \u201cBitcoin has been accepted, but nobody uses it,\u201d says Johns Hopkins\u2019 Green.<\/p>\n Which is where Pornhub might be able to make the most impact, not because of its content, but because of its scale. It\u2019s the 32nd biggest site on the web, according to<\/a> Alexa site rankings, putting it just behind Netflix and Twitch. Its customers are likely more motivated than others to seek anonymity online. As long as they\u2019re clear-eyed about the potential downsides of Verge and other cryptocurrencies, they could help the new payment systems in general find a place in transactions, rather than being just an asset to collect.<\/p>\n
