Nym gets $6M for its anonymous overlay mixnet to sell privacy as a service – TechCrunch

Switzerland-based privacy startup Nym Technologies has raised $6 million, which is being loosely pegged as a Series A spherical.

Earlier raises included a $2.5M seed spherical in 2019. The founders additionally took in grant cash from the European Union’s Horizon 2020 analysis fund throughout an earlier R&D section growing the community tech.

The newest funding shall be used to proceed industrial improvement of community infrastructure which mixes an previous thought for obfuscating the metadata of knowledge packets on the transport community layer (Mixnets) with a crypto impressed repute and incentive mechanism to drive the required high quality of service and assist a resilient, decentralized infrastructure.

Nym’s pitch is it’s constructing “an open-ended anonymous overlay network that works to irreversibly disguise patterns in Internet traffic”.

Unsurprisingly, given its consideration to crypto mechanics, buyers within the Series A have sturdy crypto ties — and cryptocurrency-related use-cases are additionally the place Nym expects its first customers to come from — with the spherical led by Polychain Capital, with participation from a variety of smaller European buyers together with Eden Block, Greenfield One, Maven11, Tioga, and 1kx.

Commenting in a assertion, Will Wolf of Polychain Capital, mentioned: “We’re incredibly excited to partner with the Nym team to further their mission of bringing robust, sustainable and permissionless privacy infrastructure to all Internet users. We believe the Nym network will provide the strongest privacy guarantees with the highest quality of service of any mixnet and thus may become a very valuable piece of core internet infrastructure.”

The Internet’s ‘original sin’ was that core infrastructure wasn’t designed with privacy in thoughts. Therefore the extent of complicity concerned in Mixnets — shuffling and delaying encrypted knowledge packets so as to defend sender-to-recipient metadata from adversaries with a world view of a community — most likely appeared like over engineering all the way in which again when the net’s scaffolding was being pieced collectively.

But then got here Bitcoin and the crypto growth and — additionally in 2013 — the Snowden revelations which ripped the veil off the NSA’s ‘collect it all’ mantra, as Booz Allen Hamilton sub-contractor Ed risked all of it to dump knowledge on his personal (and different) governments’ mass surveillance applications. Suddenly community stage adversaries have been entrance web page information. And so was Internet privacy.

Since Snowden’s huge reveal, there’s been a gradual burn of momentum for privacy tech — with rising client consciousness fuelling utilization of providers like e2e encrypted electronic mail and messaging apps. Sometimes in spurts and spikes, associated to particular knowledge breaches and scandals. Or certainly privacy-hostile coverage adjustments by mainstream tech giants (hi Facebook!).

Legal clashes between surveillance legal guidelines and knowledge safety rights are additionally inflicting rising b2b complications, particularly for US-based cloud providers. While development in cryptocurrencies is driving demand for safe infrastructure to assist crypto buying and selling.

In quick, the chance for privacy tech, each b2b and consumer-facing, is rising. And the workforce behind Nym thinks circumstances look ripe for common objective privacy-focused networking tech to take off too.

Of course there may be already a well-known anonymous overlay community in existence: Tor, which does onion routing to obfuscate the place site visitors was despatched from and the place it finally ends up.

The node-hopping element of Nym’s community shares a characteristic with the Tor community. But Tor doesn’t do packet mixing — and Nym’s contention is that a useful mixnet can present even stronger network-level privacy.

It units out the case on its website — arguing that “Tor’s anonymity properties can be defeated by an entity that is capable of monitoring the entire network’s ‘entry’ and ‘exit’ nodes” because it doesn’t take the additional step of including “timing obfuscation” or “decoy traffic” to obfuscate the patterns that might be exploited to deanonymize customers.

“Although these kinds of attacks were thought to be unrealistic when Tor was invented, in the era of powerful government agencies and private companies, these kinds of attacks are a real threat,” Nym suggests, additional noting one other distinction in that Tor’s design is “based on a centralized directory authority for routing”, whereas Nym totally decentralizes its infrastructure.

Proving that suggestion shall be fairly the problem, after all. And Nym’s CEO is upfront in his admiration for Tor — saying it’s the greatest know-how for securing internet looking proper now.

“Most VPNs and almost all cryptocurrency projects are not as secure or as private as Tor — Tor is the best we have right now for web browsing,” says Nym founder and CEO Harry Halpin. “We do assume Tor made all the proper selections once they constructed the software program — on the time there was no curiosity from enterprise capital in privacy, there was solely curiosity from the US authorities. And the Internet was too gradual to do a mixnet. And what’s occurred is pace up 20 years, issues have reworked.

“The US government is no longer viewed as a defender of privacy. And now — weirdly enough — all of a sudden venture capital is interested in privacy and that’s a really big change.”

With such a excessive stage of complexity concerned in what Nym’s doing it should, very evidently, want to exhibit the robustness of its community protocol and design towards assaults and vulnerabilities on an ongoing foundation — such as these looking for to spot patterns or establish dummy site visitors and give you the option to relink packets to senders and receivers.

The tech is open supply however Nym confirms the plan is to use a number of the Series A funding for an impartial audit of latest code.

It additionally touts the variety of PhDs it’s employed to-date — and plans to rent a bunch extra, saying will probably be utilizing the brand new spherical to greater than double its headcount, together with hiring cryptographers and builders, as effectively as advertising and marketing specialists in privacy.

The principal motivation for the elevate, per Halpin, is to spend on extra R&D to discover — and (he hopes) — clear up a number of the extra particular use-cases it’s kicking round, past the essential one in every of letting builders use the community to defend consumer site visitors (a la Tor).

Nym’s whitepaper, for instance, touts the chance for the tech getting used to allow customers to show they’ve the proper to entry a service with out having to disclose their precise identification to the service supplier.

Another huge distinction vs Tor is that Tor is a not-for-profit — whereas Nym needs to construct a for-profit enterprise round its Mixnet.

It intends to cost customers for entry to the community — so for the obfuscation-as-a-service of getting their knowledge packets blended into a crowd of shuffled, encrypted and proxy node-hopped others.

But doubtlessly additionally for some extra bespoke providers — with Nym’s workforce eyeing particular use-cases such as whether or not its community may supply itself as a ‘super VPN’ to the banking sector to defend their transactions; or present a safe conduit for AI corporations to perform machine studying processing on delicate data-sets (such as healthcare knowledge) with out risking exposing the information itself.

“The main reason we raised this Series A is we need to do more R&D to solve some of these use-cases,” says Halpin. “But what impressed Polychain was they said wow there’s all these people that are actually interested in privacy — that want to run these nodes, that actually want to use the software. So originally when we envisaged this startup we were imagining more b2b use-cases I guess and what I think Polychain was impressed with was there seemed to be demand from b2c; consumer demand that was much higher than expected.”

Halpin says they anticipate the primary use-cases and early customers to come from the crypto area — the place privacy considerations routinely connect themselves to blockchain transactions.

The plan is to launch the software program by the tip of the 12 months or early subsequent, he provides.

“We will have at least some sort of chat applications — for example it’s very easy to use our software with Signal… so we do think something like Signal is an ideal use-case for our software — and we would like to launch with both a [crypto] wallet and a chat app,” he says. “Then over the next year or two — because we have this runway — we can work more on kind of higher speed applications. Things like try to find partnerships with browsers, with VPNs.”

At this (nonetheless pretty early) stage of the community’s improvement — an preliminary testnet was launched in 2019 — Nym’s eponymous community has amassed over 9,000 nodes. These distributed, crowdsourced suppliers are solely incomes a NYM repute token for now, and it stays to be seen how a lot exchangeable crypto worth they could earn sooner or later as suppliers of key infrastructure if/when utilization takes off.

Why didn’t Mixnets as a know-how take off earlier than, although? After all the thought dates again to the Eighties. There’s a vary of causes, in accordance to Halpin — points with scalability being one in every of them one. And a key design “innovation” he factors to vis-a-vis its implementation of Mixnet know-how is the flexibility to hold including nodes so the community is ready to scale to meet demand.

Another key addition is that the Nym protocol injects dummy site visitors packets into the shuffle to make it tougher for adversaries to decode the trail of any explicit message — aiming to bolster the packet mixing course of towards vulnerabilities like correlation assaults.

While the Nym community’s crypto-style repute and incentive mechanism — which works to guarantee the standard of blending (“via a novel proof of mixing scheme”, as its whitepaper places it) — is one other differentiating element Halpin flags.

“One of our core innovations is we scale by adding servers. And the question is how do we add servers? To be honest we added servers by looking at what everyone had learned about reputation and incentives from cryptocurrency systems,” he tells TechCrunch. “We copied that — these insights — and connected them to combine networks. So the mixture of the 2 issues finally ends up being fairly highly effective.

“The technology does essentially three things… We mix packets. You want to think about an unencrypted packet like a card, an encrypted packet you flip over so you don’t know what the card says, you collect a bunch of cards and you shuffle them. That’s all that mixing is — it just randomly permutates the packets… Then you hand them to the next person, they shuffle them. You hand them to the third person, they shuffle them. And then they had the cards to whoever is at the end. And as long as different people gave you cards at the beginning you can’t distinguish those people.”

More usually, Nym additionally argues it’s a bonus to be growing mixnet know-how that’s impartial and common objective — folding all types and forms of site visitors into a shuffled pack — suggesting it could possibly obtain higher privacy for customers’ packets on this pooled crowd vs comparable tech supplied by a single supplier to solely their very own customers (such as the ‘privacy relay’ network recently announced by Apple).

In the latter case, an attacker already is aware of that the relayed site visitors is being despatched by Apple customers who’re accessing iCloud providers. Whereas — as a common objective overlay layer — Nym can, in concept, present contextual protection to customers as a part of its privacy combine. So one other key level is that the extent of privacy out there to Nym customers scales as utilization does.

Historical efficiency points with bandwidth and latency are different causes Halpin cites for Mixnets being largely left on the tutorial shelf. (There have been another deployments, such as Loopix — which Nym’s whitepaper says its design builds on by extending it into a “general purpose incentivized mixnet architecture” — however it’s truthful to say the know-how hasn’t precisely gone mainstream.)

Nonetheless, Nym’s rivalry is the tech’s time is lastly coming; firstly as a result of technical challenges related to Mixnets might be overcome — due to positive aspects in Internet bandwidth and compute energy; as effectively as by way of incorporating crypto-style incentives and different design tweaks it’s introducing (e.g. dummy site visitors) — but in addition, and maybe most significantly, as a result of privacy considerations aren’t merely going to disappear.

Indeed, Halpin suggests governments in sure nations could in the end determine their publicity to sure mainstream tech suppliers that are topic to state mass surveillance regimes — whether or not that’s the US model or China’s taste or elsewhere —  merely isn’t tenable over the longer run and that trusting delicate knowledge to company VPNs primarily based in nations topic to intelligence company snooping is a idiot’s sport.

(And it’s fascinating to word, for instance, that the European Data Protection Supervisor is currently conducting a review of EU bodies use of mainstream US cloud services from AWS and Microsoft to test whether or not they’re in compliance with final summer time’s Schrems II ruling by the CJEU, which struck down the EU-US Privacy Shield deal, after once more discovering US surveillance regulation to be primarily incompatible with EU privacy rights… )

Nym is betting that some governments will — ultimately — come trying for different know-how options to the spying drawback. Although authorities procurement cycles make that play a longer sport.

In the close to time period, Halpin says they anticipate curiosity and utilization for the metadata-obscuring tech to come from the crypto world the place there’s a want to defend transactions from view of potential hackers.

“The websites that [crypto] people use — these exchanges — have also expressed interest,” he notes, flagging that Nym additionally took in some funding from Binance Labs, the VC arm of the cryptocurrency alternate, after it was chosen to undergo the Lab’s incubator program in 2018.

The problem for crypto customers is their networks are (comparatively) small, per Halpin — which makes them weak to deanonymization assaults.

“The thing with a small network is it’s easy for random people to observe this. For example people who want to hack your exchange wallet — which happens all the time. So what cryptocurrency exchanges and companies that deal with cryptocurrency are concerned about is typically they do not want the IP address of their wallet revealed for certain kinds of transactions,” he provides. “This is a real problem for cryptocurrency exchanges — and it’s not that their enemy is the NSA; their enemy could be — and almost always is — an unknown, often lone individual but highly skilled hacker. And these kinds of people can do network observations, on smaller networks like cryptocurrency networks, that are essentially are as powerful as what the NSA could do to the entire Internet.”

There at the moment are a vary of startups looking for to decentralize numerous facets of Internet or frequent computing infrastructure — from file storage to decentralized DNS. And whereas a few of these tout elevated safety and privacy as core advantages of decentralization — suggesting they will ‘fix’ the issue of mass surveillance by having an structure that massively distributes knowledge, Halpin argues that a privacy declare being routinely connected to decentralized infrastructure is misplaced. (He factors to a paper he co-authored on this matter, entitled Systematizing Decentralization and Privacy: Lessons from 15 Years of Research and Deployments.)

“Almost all of those projects gain decentralization at the cost of privacy,” he argues. “Because any decentralized system is easier to observe because the crowd has been spread out… than a centralized system — to a large extent. If the adversary is sufficiently powerful enough all the participants in the system. And historically we believe that most people who are interested in decentralization are not expects in privacy and underestimate how easy it is to observe decentalized systems — because most of these systems are actually pretty small.”

He factors on the market are “only” 10,000 full nodes in Bitcoin, for instance, and a comparable quantity in Ethereum — whereas different, newer and extra nascent decentralized providers are seemingly to have fewer nodes, possibly even simply a few hundred or thousand.

And whereas the Nym community has a comparable quantity of nodes to Bitcoin, the distinction is it’s a mixnet too — so it’s not simply decentralized however it’s additionally utilizing a number of layers of encryption and site visitors mixing and the assorted different obfuscation steps which he says “none of these other people do”.

“We assume the enemy is observing everything in our software,” he provides. “We are not what we call ‘security through obscurity’ — security through obscurity means you assume the enemy just can’t see everything; isn’t looking at your software too carefully; doesn’t know where all your servers are. But — realistically — in an age of mass surveillance, the enemy will know where all your services are and they can observe all the packets coming in, all the packets coming out. And that’s a real problem for decentralized networks.”

Post-Snowden, there’s actually been rising curiosity in privacy by design — and a handful of startups and firms have been in a position to construct momentum for providers that promise to defend customers’ knowledge, such as DuckDuckGo (non-tracking search); Protonmail (e2e encrypted electronic mail); and Brave (privacy-safe looking). Apple has additionally, after all, very efficiently markets its premium {hardware} beneath a ‘privacy respecting’ banner.

Halpin says he needs Nym to be a part of that motion; constructing privacy tech that may contact the mainstream.

“Because there’s a lot enterprise capital floating into the market proper now I believe we’ve a as soon as in a technology likelihood — simply as everybody was enthusiastic about p2p in 2000 — we’ve a as soon as in a technology likelihood to construct privacy know-how and we must always construct corporations which natively assist privacy, quite than simply making an attempt to bolt it on, in a half hearted method, onto non-privacy respecting enterprise fashions.

“Now I think the real question — which is why we didn’t raise more money — is, is there enough consumer and business demand that we can actually discover what the cost of privacy actually is? How much are people willing to pay for it and how much does it cost? And what we do is we do privacy on such a fundamental level is we say what is the cost of a privacy-enhanced byte or packet? So that’s what we’re trying to figure out: How much would people pay just for a privacy-enhanced byte and how much does just a privacy enhanced byte cost? And is this a small enough marginal cost that it can be added to all sorts of systems — just as we added TLS to all sorts of systems and encryption.”
