What is a CDN?

Content Delivery Networks are a crucial part of the internet infrastructure that most people use every day without realizing it. David Rhodus explains:

"Today, three to four billion people use a CDN every day, so about 80, 90% of internet traffic goes through CDNs. What they do is they'll connect to a web server like CNN, Fox News, dot com, whatever. They'll fan that website out across the globe in a set of caches to make it load faster for the individual users."

CDNs have been around for about 25 years, with the last major wave of innovation occurring around 15 years ago with the introduction of Anycast technology and BGP hijacking to improve loading speeds. However, since then, the industry has remained relatively stagnant, creating an opportunity for new players like Pipe Network to enter the market with fresh ideas.

The Problem with Traditional CDNs

While current CDNs have significantly improved content delivery speeds, they still face limitations. Rhodus highlights one of the main issues:

"If you look at a traditional CDN like CloudFlare or the bigger ones like Akamai, those cache nodes are about 150 miles from the user, so that's still considerable distance, so that introduces quite a bit of latency."

This distance between the cache nodes and end-users results in latency typically ranging from 80 to 150 milliseconds. As internet users demand faster and more responsive experiences, especially with the rise of streaming video and real-time applications, there's a clear need for improvement in this area.

Pipe Network's Innovative Approach

Pipe Network aims to address these limitations by leveraging blockchain technology and a novel approach to node distribution. Rhodus explains their goal:

"Our model is to get that cache data about 50 to 20 miles to the user, and it's amazing, so if you look at traditional CDN, they're 80, 150 milliseconds of latency. When you're in like the 20 mile range from the user, you're seeing like single digit millisecond latency."

This dramatic reduction in latency is achieved through what Pipe Network calls "hyper-local nodes." By bringing the content closer to the end-user, Pipe Network can significantly improve loading times and overall user experience.

The Role of Blockchain in Pipe Network

While the idea of distributed nodes isn't new in the CDN world, Pipe Network's use of blockchain technology sets it apart. Rhodus elaborates on how blockchain fits into their model:

"Using blockchain for coordinating nodes is fascinating, and it allows us to have what people would call as a hyper-local node, and for CDN, that's really important to get that last mile down closer to the user."

The blockchain component allows for a more decentralized and flexible network of nodes, enabling Pipe Network to achieve greater geographical coverage and adapt more quickly to changing demand patterns.

Verifying Node Performance

One of the challenges in operating a decentralized network is ensuring that nodes are actually performing the work they claim to be doing. Pipe Network has developed an innovative solution to this problem, which Rhodus calls ZKTCP:

"We use two protocols. We use QUIC, which is what Solana uses today. We use that for rapidly getting the cache data to the nodes. Then when we're serving the data, we use traditional TCP. All browsers just work magically. We went back and we looked at how can we perform like a zero-knowledge proof on a TCP session."

This novel approach allows Pipe Network to verify the work done by nodes without introducing significant latency, a crucial factor in maintaining the network's performance advantages.

Tokenomics and Incentives

Like many blockchain-based projects, Pipe Network incorporates a token system to incentivize node operators. Rhodus explains their approach:

"We used the Burnment equilibrium. A customer grow and he'll acquire some pipe. He'll burn it for the bandwidth data credits. Then as the node services that, they'll get pipe tokens essentially for verified proof of work that they did the bandwidth egress."

This model ensures that node operators are rewarded for their contributions to the network, while also creating a sustainable economic model for the project.

Scaling the Network

One of the key challenges for any DePIN project is achieving sufficient scale to compete with established players. Pipe Network has made impressive progress in this area, with Rhodus revealing:

"We've got great coverage right now. We've not done any bounties. It's just been Wild West, sign up, run a node, break the software if you can, early days of a project. We've got 200 and something thousand nodes out there today."

This rapid growth demonstrates the interest in Pipe Network's approach and suggests that the project has the potential to achieve the scale necessary to compete with traditional CDNs.

The Potential Impact on Video Streaming

One area where Pipe Network's improvements could have a significant impact is in video streaming. Rhodus highlights the current limitations:

"It's difficult if almost impossible to stream real 4K video still. Just a few weeks ago, we saw a huge meltdown of live streaming with a boxing match on Netflix, and that's some of the best infrastructure in this world."

By reducing latency and improving geographical coverage, Pipe Network could enable higher quality video streaming and more reliable live events, addressing pain points that even the largest tech companies struggle with today.

Building on Solana

While Pipe Network is designed to be blockchain-agnostic, the project is currently built on Solana. Rhodus explains the reasoning behind this choice:

"It was more just like coincidence I randomly got connected to Anatoly didn't actually really know who he was or very little about Solana actually and we're just like talking random like erasure and coding aircriction stuff like just nerd stuff right and like while you're running this blockchain like you're one of the most heavy engineering person I've met in like the script that we have had three environments so it gave me a lot of comfort to like use Solana for innovation there."

This connection to Solana's technical expertise has led to a fruitful collaboration, with Pipe Network potentially contributing improvements to Solana's infrastructure in the future.

The Future of CDNs and Edge Computing

Pipe Network's innovations have implications beyond just improving existing CDN services. Rhodus sees potential for new applications in edge computing:

"We think it will not only revolutionize the CDN industry, it's going to open a new area of innovation, I think, for edge-based compute and things like that."

This could enable new types of applications that require low-latency processing close to the end-user, opening up possibilities in areas like augmented reality, IoT, and more.

Competing with Established Players

While Pipe Network's technology shows promise, the CDN market is dominated by large, established players. Rhodus acknowledges the challenge but sees opportunities:

"We went out and we looked at Akamai's APIs and just, okay, we can mimic those. It makes it super easy to just plug and play us."

By making it easy for existing CDN customers to integrate Pipe Network, the project aims to gradually gain market share by proving its performance advantages in real-world scenarios.

The Role of AI in CDNs

An interesting development in the CDN space is the growing importance of AI, particularly for inference at the edge. Rhodus sees this as a potential opportunity for Pipe Network:

"We've got quite a bit happening on AI inference side like half half of the people testing pipe today are using it for like chatbots LOMs like things we didn't foresee so yeah I love that like beautiful new ground that we're touching and we have a roadmap for like helping build out AI inference and get that down to like you know 10 20 millisecond latency."

This unexpected use case demonstrates the potential for Pipe Network to serve emerging technologies beyond traditional content delivery.

The Environmental Impact of CDNs

While much attention has been paid to the energy consumption of cryptocurrencies and AI, Rhodus points out that CDNs are already a significant consumer of electricity:

"If you look at like global video streaming that's over 3% of the world's electricity used every year for servicing streaming video so CDNs alone are about 1.5 1.1 1.2%."

This highlights the importance of improving CDN efficiency, not just for performance reasons but also for environmental sustainability.

Advice for Crypto Founders

As a former non-crypto founder now working in the blockchain space, Rhodus offers valuable advice for other entrepreneurs considering entering the crypto world:

"Don't focus on crypto at all until you've got users in revenue and then you know strap a blockchain onto the product at that point but I would go as long as possible without entering any blockchain crypto web 3 mindset and just focus on a product."

This pragmatic approach emphasizes the importance of building a solid product and business model before integrating blockchain technology.

The Future of Pipe Network

Looking ahead, Pipe Network has ambitious plans. Rhodus shares:

"I think we're gonna push into production very soon this summer we've got a lot of super cool features we're gonna add on it's like traditional CDN things of like video transcoding we've got a bunch of partners coming in from even even other blockchains asking for features like this so really excited to collaborate."

This indicates that Pipe Network is not just focused on competing with traditional CDNs but also on serving the unique needs of the blockchain ecosystem.

Challenges and Opportunities in the DePIN Space

The discussion touched on the broader challenges and opportunities in the Decentralized Physical Infrastructure Network (DePIN) space. While some DePIN projects have faced difficulties in achieving sustainable business models, Rhodus sees potential for Pipe Network to succeed by focusing on solving real problems for customers:

"We immediately are solving a problem for these customers we don't go say give us your hundred million dollar a month contract you know we come in and prove ourselves with like very valuable work to the client."

This customer-centric approach could help Pipe Network avoid some of the pitfalls that have affected other DePIN projects.

The Importance of Geographical Coverage

One of the key advantages of Pipe Network's decentralized approach is the potential for improved geographical coverage. Rhodus explains:

"45% of the world still is like in a rural area outside of a metropolitan so there still needs to be a large quantity of nodes out there. Those don't have to be as dense as far as like number of nodes but the nodes need to be super high quality like one gigabit, 10 gigabit, 40 gigabit, it's really high networking as possible."

This focus on both urban and rural areas could help Pipe Network provide better service in regions that are currently underserved by traditional CDNs.

The Potential Impact on Emerging Markets

Rhodus highlighted an interesting side effect of Pipe Network's model:

"Depending on where these people are located in certain areas of the world like Nigerian stuff. They're making a week worth of groceries per day. It's really beautiful to see the positive impact on certain areas of the world."

This suggests that Pipe Network could have a positive economic impact in emerging markets, providing income opportunities through node operation.

The Role of DNS in Pipe Network's Solution

An interesting technical aspect of Pipe Network's solution is their approach to DNS:

"We call it pipe DNS at this point. It's some kind of next generation of DNS. It has all kinds of semantic contextual awareness of the data that has been cached and what the users are requesting."

This innovative use of DNS could further improve content delivery speeds by more efficiently routing users to the most appropriate nodes.

Comparing Pipe Network to Traditional CDN Providers

When discussing the potential market impact of Pipe Network, Rhodus provided some interesting comparisons to existing CDN providers:

"In the CDN space you look at this company called Akama right they have a market cap today of like 11 billion they have twice the revenue a cloud player and if you look at cloud player they have a market cap of 54 billion and they had 25% growth last year it's great so investors are super hyped up you'll not find a tier one media company using cloud player because the lights are too high."

This comparison highlights the potential for disruption in the CDN market and suggests that there's room for new players like Pipe Network to capture significant market share.

The Intersection of CDNs and AI

An interesting development discussed in the podcast is the growing intersection between CDNs and AI, particularly in the area of inference:

"Very recently Microsoft just pulled back I think about 80 billion and new investments and data centers for AI yeah there's some videos out CEO talking about how they're building out what they call it's very cool to me it's like hyperscale edge fleets to serve inference and I look at that and I think well that's exactly what Deepin's doing."

This suggests that Pipe Network's technology could be well-positioned to serve the growing demand for edge AI inference, potentially opening up new markets beyond traditional content delivery.

The Importance of Proof of Work in DePIN Networks

Rhodus emphasized the importance of proof of work in DePIN networks like Pipe Network:

"We love proof of work like I think proof of stakes fascinating for l1s but you know for services that are delivering like data computation things like that they just have to be proof of work."

This commitment to proof of work for verifying node performance sets Pipe Network apart from some other blockchain projects and could provide advantages in terms of security and reliability.

The Potential for Collaboration with Other Blockchains

While Pipe Network is currently built on Solana, Rhodus indicated openness to collaboration with other blockchain projects:

"We've got a bunch of partners coming in from even even other blockchains asking for features like this so really excited to collaborate you know with you know some other like aptosui stealth chains out there."

This suggests that Pipe Network could potentially become a cross-chain infrastructure provider, serving the needs of multiple blockchain ecosystems.

The Role of Community in Crypto Projects

Rhodus offered an interesting perspective on the role of community in crypto projects:

"I think if project has revenue that community is gonna organically pop up right away."

This focus on building a sustainable business model before cultivating a community stands in contrast to some other crypto projects that prioritize community building from the outset.

The Future of Edge Computing

Throughout the discussion, it became clear that Pipe Network's technology has implications beyond just content delivery. The ability to provide low-latency, geographically distributed computing resources could enable new types of applications and services. As edge computing becomes increasingly important for technologies like IoT, AR/VR, and autonomous vehicles, Pipe Network's infrastructure could play a crucial role in enabling these next-generation applications.

In conclusion, Pipe Network represents an exciting development in the CDN space, leveraging blockchain technology and innovative approaches to node distribution to potentially revolutionize content delivery. While challenges remain in scaling the network and competing with established players, the project's focus on solving real customer problems and its potential applications beyond traditional CDNs make it a compelling player to watch in the evolving landscape of internet infrastructure.
