Once emitted, carbon can remain in our atmosphere for hundreds of years. To survive climate change, massive amounts of carbon emissions have to be offset – and fast. According to a UN report, 10 billion tons of carbon emissions will have to be removed on a yearly basis by 2050 to prevent the planet from moving past the 2 degree Celsius threshold. Allowing the climate to heat by just one more degree would have unprecedented consequences – including the sinking of islands and coastal areas, an accelerated rate of extinction (right now, estimations suggest that about 24 to 150 species go extinct every day) and much more. Our complacency towards climate change proves that we’re still in denial of the chain reaction and butterfly effects of our past and present actions.

Clearly, we’ve already crossed the threshold in the climate crisis where we had enough time for long debates on potential measures and policies. The time for those debates was in the 1960s, when a report by former US President Johnson’s Science Advisory Committee first warned about the risks and dangers of excessive carbon emissions. “Climate change is the result of more than a century of unsustainable energy and land use, lifestyles and patterns of consumption and production,” said Jim Skea, one of the IPCC Working Group III Co-Chairs in a press release published earlier this month. According to a report published by the Intergovernmental Panel on Climate Change (IPCC), we can still achieve our climate goals if we significantly reduce emissions across all economic sectors. However, we urgently need to take action to limit global warming to 1.5 degrees Celsius.

Now is the time to act. Now is the time for bold moves. As Skea put it: “Without immediate and deep emissions reductions across all sectors, it will be impossible.”

The astonishing carbon footprint of the Internet

While people are legitimately obsessing about the emissions caused by air travel and whether to take that plane or not – bestowing us with concepts like ‘flight shaming’ – other industries’ significant impacts almost go unnoticed. One of them is the Internet.

Think about the chat messages and emails you send out every day. How many times do you ‘google’ things? How much time do you spend streaming music or videos? All of your online activities add to your carbon footprint. There are a couple grams of carbon emissions attached to the energy needed to power your devices and the wireless networks you connect to. On top of that comes the significant amount of energy required to support the infrastructure of today’s Internet, namely millions of data centers and the thousands of servers in each of them.

Even though the emissions caused by streaming one song or sending one email may seem insignificant, the accumulated use of the Internet by billions of people all over the world adds up. It actually leads to a collective carbon footprint amounting to a share of roughly 3.7% of global emissions caused by the Internet and its infrastructure – and these carbon emissions are estimated to double within the next three years. This 3.7% share of global emissions by the Internet almost makes the global aviation industry with its estimated 2.1% emissions look good.

The global pandemic – while decreasing emissions in aviation due to travel bans – has already accelerated Internet consumption and the resulting footprint due to increased streaming behaviour, remote work and more. With 1 billion people and 75 billion IoT devices expected to join the Internet economy by 2025, a more sustainable infrastructure than power-hungry data centers is urgently needed to meet the future growth of the Internet in an ethical and sustainable way.

Data Centers are power hungry

Big tech corporations like Amazon, for example, have massive carbon footprints with their corporate facilities, power-hungry data centers, complex operations and more. One larger data center alone consumes up to 120 MW – and there are about 7.2 million data centers worldwide, according to Statista. Moreover, a data center’s energy consumption accounts for about 40% of its operating costs. In 2020, Amazon emitted more than 60 million metric tons of carbon dioxide up from about 51 million in 2019. Others like Google try to downplay their energy consumption by switching to renewable energy. While renewable energy is an improvement for sure, it does not change the fact that Google’s energy consumption could power entire countries.

Is that really a desirable way for us to use the still scarce supply of renewable energy? Shouldn’t we rather focus on the root problem and on becoming more energy efficient in the first place?

The first step should be to reduce the Internet’s energy consumption and overall carbon footprint. But even then: reducing that energy consumption and transitioning to clean energy will only get us so far – particularly when considering that there simply is not enough clean energy to achieve a complete transition. Those emissions that cannot be cut have to be compensated for. A holistic solution to today’s Internet’s inefficiencies and emissions is needed.

An energy-efficient and regenerative Internet

In December 2021, ThreeFold announced its commitment to achieve a carbon double win for its open-source peer-to-peer Internet infrastructure, the ThreeFold Grid. The ThreeFold Grid is able to scale anywhere electricity and network exist, using about 10 times less energy than any comparable alternative while being more affordable as well. By starting from scratch at the operating system level, ThreeFold was able to build an Internet infrastructure that is highly energy efficient. This infrastructure is already made up of thousands of 3Nodes that are spread across 75 countries and counting.

Together with Take Action Global (TAG), an expert on climate education and action, ThreeFold aims to make the ThreeFold Grid planet-positive by removing its carbon emissions from the atmosphere three times in the form of Voluntary Carbon Credits. While the pilot for this initiative was announced to start in January 2022, ThreeFold and TAG were so eager to take action against climate change, they kicked-off the pilot one month early in December 2021. It is the first step in ThreeFold’s plan to support the use of ‘nature-based climate solutions’ like tree planting to absorb twice more carbon than the ThreeFold Grid emits by 2022. 

A silver lining on the horizon

Every industry and organization has to pull their own weight. There is no way around it. Far-reaching actions and transformations are needed across industries to limit global warming to bearable levels. “The decisions we make now can secure a liveable future. We have the tools and know-how required to limit warming,” said Hoesung Lee, IPCC Chair, in an April 2022 press release. Together with TAG, ThreeFold leads the way by working on energy-efficient and sustainable solutions for the Internet. The new IPCC report gives us a reason to be optimistic about our future and have hope for the regeneration of our planet.

Really, all it takes right now is widespread support and adoption of more energy-efficient, sustainable alternatives across industries like ThreeFold for the Internet – something that is up to each and every one of us. Let us all take action for a fairer, more sustainable world.

In October 2008, when the financial crisis was in full swing, an anonymous individual or group under the pseudonym ‘Satoshi Nakamoto’ published a white paper on Bitcoin, a “peer-to-peer electronic cash system” that ended up disrupting the financial system and sparked the creation of an entirely new industry: crypto mining.

Considering that many people view Bitcoin as a commodity, similar to gold, it only makes sense that the process of generating new Bitcoins would become referred to as ‘mining’. In a way, mining is an incentive mechanism to reach consensus in the verification of transactions in a decentralized network. While crypto mining originated from Bitcoin, the system has spread quite widely across the blockchain space.

More than a decade later, Bitcoin keeps intriguing individuals and organizations all around the world, and has become one of the most popular financial assets. Nevertheless, criticism and doubts around Bitcoin and crypto mining remain. The most popular cryptocurrency is also frequently brought to the spotlight around its potential affiliations to money laundering, financing of terrorism and cybercrime, as well as the energy the mining process of its cryptocurrency consumes. 

According to the Bitcoin Electricity Consumption Index of the University of Cambridge, the annual consumption of Bitcoin is currently estimated to amount to nearly 140 TWh. The United Arab Emirates (113 TWh) or the Netherlands (109 TWh) had a lower annual energy consumption than Bitcoin in 2020. Moreover, news outlets like The Guardian or BBC News reported on Bitcoin exceeding the energy consumption of further countries, including Ireland and Argentina. Within the last year, headlines like “Bitcoin Uses More Electricity Than Many Countries” in the New York Times or “Bitcoin’s growing energy problem: ‘It’s a dirty currency’” in the Financial Times were in no short supply.

Among the most popular quotes on the topic is Bill Gates’ statement in the New York Times in March 2021: “Bitcoin uses more electricity per transaction than any other method known to mankind, and so it’s not a great climate thing.” Not that this statement or the awareness of the issue would have prevented Microsoft from launching ION, a decentralized digital identity system, to run on the Bitcoin network.

But why is Bitcoin mining so energy intensive anyways?

At the heart of Bitcoin’s energy-intensive model is the Proof-of-Work (PoW) protocol. Bitcoin mining, the process of creating new Bitcoins using PoW, requires solving complex cryptographic equations to receive the rewards associated with the creation of the next block in the blockchain. PoW is carried out by computers, known as ‘miners’. 

In the early days, a simple computer was enough to mine Bitcoin. However, the difficulty of the mining algorithm increased as the network grew larger and more people started competing to earn the next block’s rewards. On average, it takes about 10 minutes to solve such an equation and to mine a new block. Today, Bitcoin mining has become a costly and elaborate endeavour – accessible only to large investors that can support powerful supercomputers – at the cost of local communities.

It’s only sensible that miners are beefing up their machines to increase their chances. In fact, the sector became so competitive that Intel created dedicated chips and specialized manufacturers for mining servers like Bitmain were established. With up to 3,250 Watts indicated by manufacturers, the power consumption of such devices averages 28,470 kWh per year if operated continuously. In comparison, the annual consumption of a freezer is estimated between 200 and 500 kWh per year. 

Additionally, operating a single mining machine is hardly the way to succeed. The biggest Bitcoin miners have fleets of hundreds of machines in so-called ‘mining farms’, carefully maintained and constantly ventilated, to prevent them from overheating. Some of the largest, like Northern Data in Texas, have an energy consumption of 1 GWh per year, the equivalent of the energy produced by about 3.1 million photovoltaic (solar) panels. 

In critical times where humanity is facing serious global challenges in relation to climate change and the collapse of biodiversity, we must rethink the basics of how to decentralize our world. 

Are there more energy-conscious solutions?

Proof-of-Stake (PoS) mechanisms have proven to be less energy intensive than PoW. With PoS, miners lock up (‘stake’) a blockchain’s cryptocurrency on escrow accounts to be granted mining rights. In exchange for this participation, miners receive an interest proportional to their stake as reward. 

PoS-based blockchains are faster and much more energy efficient than PoW-based blockchains. However, the implementation of a PoS protocol poses its own challenges. For example, it is known for incentivizing hoarding, rather than utilization, and driving centralization. The mining industry is attempting to shift perceptions and move away from its climate-polluting, power-hungry image by powering large mining activities with renewable energies or by offsetting their emissions with carbon credits.

While this might sound great at first, it does not resolve the underlying issue of incredibly high energy consumption. Should we really allocate relatively scarce renewable energy resources to such energy-intensive endeavours? Or should we rather look for more efficient alternatives – considering we have all the technology to create more energy-efficient models from scratch – and then support what energy consumption remains with renewable energy? 

ThreeFold Farming offers a greener paradigm

ThreeFold Farming is a decentralized, energy-efficient and meaningful alternative to mining. ThreeFold Tokens (TFT) are minted whenever new Internet capacity in terms of compute, storage or network is added to the ThreeFold Grid by connecting computers, known as 3Nodes. 

By contributing decentralized Internet capacity to the ThreeFold Grid, independent people and organizations called ‘farmers’ earn TFT in return – based on a Proof-of-Capacity  (PoC) algorithm. PoC is autonomously carried out by ThreeFold’s extremely efficient operating system. First, Zero-OS scans the computer’s resources. Then the operating system registers the computing power and Internet storage on the ThreeFold Blockchain, making the resources available to the entire network – thereby creating a decentralized model for Internet capacity provisioning. The energy consumption of a 3Node can vary, depending on the amount of Compute Units (CUs) and Storage Units (SUs) it holds. “The average consumption for a Titan 3Node is around 26.71 KwH per hour”, says ThreeFold’s Alexandre Hannelas. 

Farming supports the realization of an open-source peer-to-peer Internet free from centralized servers and authorities. Similarly to Bitcoin, the management of transactions and the issuing of TFT is carried out collectively by the network to create a decentralized Internet economy. In a way, what Bitcoin did to money, ThreeFold does to the Internet – while using much less energy. 

“By using blockchain for what it’s good at and other pioneering technologies, such as peer-to-peer networking, to complement it, we built the most efficient Internet infrastructure in the world, and by far.” – Kristof de Spiegeleer.

Developing sustainable solutions for our planet is essential to ThreeFold’s ethos which puts our planet and people first. A famous quote, we love and frequently refer to at ThreeFold, is Albert Einstein’s “We cannot solve our problems with the same thinking we used when we create them.”

Our planet needs regenerative solutions at a large scale, and ThreeFold aims to deliver on our promise providing better solutions for our planet and people through our technology. Based on the ThreeFold Grid’s average energy consumption, we’re planting trees with our partner Take Action Global to offset the Grid’s carbon emissions three times in the form of Voluntary Carbon Credits (VCC). Our VCC system was implemented in the PoC algorithm, so every 3Node mints additional TFT to offset its own carbon emissions based on the power utilization of the individual 3Node per month. The process is fully automated and executed by the ThreeFold Blockchain.

ThreeFold’s global community of farmers is on a mission to regenerate our planet through the planet-positive ThreeFold Farming which supports tree planting and other impact initiatives by default. We’re on track to provide a planet-positive Internet and support our partners in their initiatives in fields like climate education, climate action and economic inclusion worldwide.

Farming is about so much more than crypto mining. It’s about building a better Internet and shaping the world we want to live in. Together with a community of like-minded people, we’re taking action for a better world.

If not us, who? If not now, when?

The Internet is one of humanity’s greatest inventions. In its early days, it used to be free and decentralized by nature. No single entity was able to control access to the web as it was built on the foundation of a peer-to-peer network of nodes owned by developers and researchers. Until the dot-com era. Throughout the early 2000s, large corporations took over the web. New platforms like YouTube and MySpace were launched and new infrastructure needed to be built at an extreme pace, starting the data revolution and changing the digital landscape forever. 

Twenty years down the line, the Internet’s architecture has become highly centralized – owned by a handful of large corporations that act as the gatekeepers of our digital world. What was once an open and free platform accessible to anyone has long since built up barriers and lost its neutrality. Users are trapped in a cyberspace that exploits their personal data and allows censorship, hate speech, disinformation and political targeting to thrive. 

🔗Going down the Rabbit Hole

The Wall Street Journal’s investigation “The Facebook Files” and The New York Times’ audio series “Rabbit Hole” are only some of the latest examples that depict the shocking impacts of the manipulation, mental health problems, and extremism that social media algorithms are fuelling. Nevertheless, these incidents are only a glimpse into all the ways we’re being affected and influenced about the way we see the world – by the tech giants and their algorithms. Tech giants like Google and Facebook have been surrounded by a constant stream of data privacy scandals as more and more whistleblowers expose their misconduct. However, there are plenty of other, hidden players using the tools and algorithms of social media platforms for their own agendas.

The Great Hack and the Social Dilemma are great documentaries that shed light on how the Internet as we know it became compromised. They depict how algorithms are used to mine user data, control information feeds and manipulate our digital experiences. The Trump Election and the Brexit vote were heavily influenced by private companies like Cambridge Analytica that manipulated mass audiences through social media.

By purchasing thousands of personal data points collected by social media platforms and analyzing them, companies like Cambridge Analytica are able to not only predict but influence the behaviour of each and everyone of us. Data collection and analysis to such an extent allow these companies to craft and push perfectly targeted messages to users in a way that’s optimized to sway their opinions in favour of whatever agenda they have.  

🔗Can a neutral and free Internet still exist?

On 24th of March 2022, the European Parliament and Council negotiators agreed upon the Digital Markets Act (DMA). It seeks to give users more choice by demanding the most popular apps to open up and interoperate with smaller apps. Moreover, the act aims to ensure a fairer market competition by prohibiting certain gatekeeper practices like self-preferencing and targeted advertising. This set of new EU regulations is likely to impact the daily business of tech giants significantly once it becomes law. While the DMA promises to mitigate some of the issues discussed, it is doubtful that the act will be enough to fundamentally change the current system. This is a step in the right direction, but much more needs to be done.

The Internet has become our digital home. It’s impacting our lives in many ways by creating new opportunities, and changing how we communicate and connect. Therefore, it is crucial to restore the Internet’s neutrality to ensure a fair and equal environment. We need an Internet where we can rely on data security and privacy. An Internet where we’re empowered to truly and completely have ownership of and control of our own data. An Internet that empowers us with digital sovereignty.

The Internet used to be a free movement of culture and the Web. It started with an open-source and peer-to-peer vision to connect people. And while Web 3.0 projects are looking to liberalize the Internet as we know it, most of them still rely on centralized Web 2.0 infrastructure to some degree. The world needs better, holistic solutions. ThreeFold is realizing the initial vision and promise of the Internet as an open-source, peer-to-peer planetary mesh network of nodes owned by humanity. It’s a 100% open-source and community-driven project that builds the critical, neutral infrastructure for a decentralized world – one that is built and owned by the people. With ThreeFold, individuals and organizations are empowered to store their data and run their applications on a peer-to-peer network of nodes in a way that ensures their data will not be manipulated, hacked or lost. 

Powered by a global community, ThreeFold is the world’s largest peer-to-peer Internet infrastructure with a few thousand 3Nodes connected globally and the neutral foundation for any current and future IT workload. ThreeFold is now on the verge of opening up a new Internet era free from censorship, user tracking and privacy breaches. And anyone can participate in ThreeFold’s model by building or buying a 3Node, and connecting Internet capacity from their home or office – creating a fully decentralized Internet.

Similar to the enterprise blockchain hype that happened a few years ago, Web3 seems to be repeating the same story, with lots of chatter but lagging adoption. Millions have rushed to trade crypto and NFTs attached to Web3 – with a lot of this activity based on speculation and hype – but that doesn’t mean they will replace legacy platforms anytime soon. New approaches such as DeFi (decentralized finance) don’t have the same problem of the legacy firms, but they face the challenge of scaling and mass adoption. However, many so-called ‘Web3’ solutions are not as decentralized as they seem, and still have to show they are scalable, secure and accessible enough for the mass market. This all may change, but there are clear limitations that will need to be overcome.

Whether Web3 is a marketing slogan or a true technological trend, there is a lot of money and technology behind it. Financial institutions are embracing blockchain technology and we are seeing a rising adoption of digital assets across industries. While the idea of utilizing digital currencies to exchange different forms of value in an increasingly digital world certainly makes sense, it’s a bigger leap to say that blockchain alone can support a broad set of use cases, including replacing the current Internet infrastructure.

The Internet’s client-server infrastructure replicates data and workloads across many computers, and uses tons of computing resources and energy while limiting the scalability of our applications. However, the clear inefficiencies and gaps in security in today’s centralized infrastructures are being challenged by simpler means of building, storing and exchanging data.

Blockchain is a clear evolution to the centralized client-server model, but there are severe challenges sourced from the blockchain trilemma between decentralization, scalability and security. Peer-to-peer systems transcend those challenges as they don’t require any valid2ation or verification from a third party, and enable end-to-end connections that can scale limitlessly without the potential of being altered or corrupted by intermediaries. In peer-to-peer systems, all participants are equally privileged, presenting a fairer model. Peer-to-peer represents an incredibly simple and efficient paradigm for organizing our digital world, and has already proven to be the most efficient alternative to centralized information systems.

Simply put, there is no reason to replicate full sets of data and workloads across many computers, and use tons of computing resources and energy while limiting the scalability of our applications. While there is an increasing reliance on blockchain principles to organize our Internet systems, blockchain also makes things redundant, slow, complex and energy intensive. To be clear, blockchain isn’t the problem, as it is a great technology to store and exchange value in a decentralized way, but it is only one piece of the puzzle.

By inter-connecting the computing processing power and storage capacity of billions of computers worldwide in a peer-to-peer way, data transfers could happen end-to-end between people and machines without the need to be verified. Peer-to-peer is also the only way to achieve a truly self-sovereign Internet – creating a ‘trustful’ environment that allows users and developers to have real data ownership.

Peer-to-peer systems aren’t meant to replace blockchains – they represent a way to decentralize models that blockchain cannot, such as Internet infrastructures. Peer-to-peer systems and blockchains, side by side. The best of both worlds. Peer-to-peer as the most efficient and decentralized alternative for us to exchange data and Internet resources. And blockchain for establishing trust through an irrefutable record of transactions.

With the rise of emerging technologies, a new technological foundation is needed to protect our sovereignty and freedom. The rise of blockchains, while well intended, ultimately has made the technological space more complex than ever before, and still benefits a plutocratic few (relative to its promise). More than just technology, peer-to-peer opens a world of new possibilities for humanity to co-initiate new paradigms and experiences.

By applying blockchain and peer-to-peer technology to the cloud, ThreeFold solves the security and autonomy issues of the Internet and realizes the initial promise of the Internet as an open-source, peer-to-peer, planetary mesh network of nodes owned by the people.

After introducing the ThreeFold Grid in part one and diving deep into storage and compute, we’re back with part 4 to look at the networking aspects of the ThreeFold Grid.

Computer networking is a rather complex phenomenon with a thankfully intuitive outcome: you send messages from one place to another. We all understand that our digital devices become a lot less interesting when they are not connected to the Internet. However, networking is not just Internet, and when it comes to building a new Internet, it’s important to understand what that means.

The existing Internet can be defined as a global set of networks and protocols that enable us to do things like load web pages and use apps that rely on external data. It depends on lots of underlying infrastructure, including fiber optic cables running along the ocean floor, our home routers and their connection to an Internet service provider (ISP), lots of cell service towers, and an increasing number of satellites. All of that makes the Internet possible, and it’s still required for a new Internet to function.

ThreeFold uses and builds new protocols to create a network that is interoperable with the existing Internet. These include private overlay networks, the Planetary Network based on Yggdrasil, and various interfaces to the public Internet. Let’s see how they work.

🔗Private overlay networks

Every deployment on the ThreeFold Grid belongs to a network, which is one of the Grid primitives. These networks allow data to be transmitted between workloads in a private and secure manner. They are called overlay networks because they pass traffic over some underlying network. That could be within a single node or between nodes on infrastructure provided by a farmer. The Grid uses software called WireGuard for this purpose, a simple, fast, and secure option among its alternatives.

By means of encryption, the traffic on a private overlay network is unreadable to any other device on that network. Likewise, the workloads within the private network have no visibility of the underlying network. Individuals who deploy workloads can access their networks over a secure tunnel, assuming that one of the nodes in the network is reachable from the public Internet. This is suitable for workload administration and some private applications. For public services and peer-to-peer communication, the ThreeFold Grid provides other solutions.

🔗Planetary Network

The Planetary Network is an implementation of the Yggdrasil Network, which is a next generation approach to network routing. It is a peer-to-peer solution where all traffic is encrypted and takes the shortest path to its destination. These features make it highly compatible with the ethos and goals of the ThreeFold Grid: privacy, security, and efficiency. The design also allows nodes, workloads, and users to communicate freely without relying on centralized intermediaries.

Many ThreeFold Farmers connect their nodes to a home router which blocks all inbound traffic by default. This is a sensible feature that doesn’t interfere with most Internet usage (enthusiasts who want to host their own website or a gaming server might bypass this, for example). However, nodes on the Grid need to be reachable, especially in order to receive workload definitions from deployers.

The Planetary Network solves this by accepting inbound traffic through an outbound connection to a publicly accessible peer. You can think of this like making a call to an operator and then waiting for another call to be routed to you on that line. Even if your phone is set to block all incoming calls, someone can still reach you if they can reach the operator.

This also provides a way for workloads to communicate with one another and be reachable by users. Anyone can enable the Planetary Network on their own device to access sites and services in a very secure and private way. While the ThreeFold Grid is designed to be fully interoperable with the existing Internet, the Planetary Network provides an alternative which can sit side by side in a seamless way.

🔗Reliable Message Bus

Using the Planetary Network, nodes and Grid users can send messages over the Reliable Message Bus. Notably, it is used for the delivery of workload definitions as mentioned earlier. Zero-OS supports some other RMB messages as well, for doing things like checking available capacity on a node in real time. RMB is a general purpose protocol that can be used by developers in their applications. It queries the ThreeFold Blockchain as a kind of address book for the Planetary Network, enabling nodes and users to find each other in a decentralized way.

🔗Public IPs and Web Gateways

Finally, let’s see how the Grid can offer services over the public Internet using public IP addresses and web gateways. Everytime we type a domain name into our browser, like threefold.io, it is resolved to an IP address. The browser then forms a connection with that address to retrieve the site we’re looking for. Reviving a theme from earlier, that IP must be publicly reachable.

🔗Public IPs

We’re in the midst of a shift from the older IPv4 standard to the newer IPv6 standard. While IPv6 has plenty of addresses for every device on the planet and many more, it hasn’t been universally adopted yet, and IPv4 addresses are in short supply. You likely have one assigned to your router at home, and these days, even getting a second one from your ISP can be a difficult and expensive proposition.

The ThreeFold Grid allows farmers who own blocks of IPv4 addresses to rent them out to deployers. These addresses get attached to individual workloads which are then reachable over the public Internet. A deployer could then assign their own domain name to that IP and host a website there. This is a very flexible way to make Grid deployments publicly available, but it comes at a relatively high cost.

🔗Web Gateways

Web gateways are another way to make workloads on the ThreeFold Grid available over the public Internet. In this case, the farmer may provide a domain name that points to one of their nodes which is publicly reachable. Deployers are then able to reserve a subdomain, like explorer.threefold.io is a subdomain of threefold.io, that routes traffic to their workload. It is also possible for a deployer to point their own domain to the gateway node which then routes traffic to the appropriate workloads.

We glossed over a bit in the earlier description of domain name to IP address resolution. In fact, multiple domains can point to a single IP address and this is common practice among existing web hosts. Adding similar functionality to the Grid helps to ease the demand for IPv4 addresses and is a lower cost solution for deployers than renting a dedicated IP. The web gateway also serves to enhance security and reliability of Grid-hosted services.

The gateway provides a connection from the public Internet to the secure private overlay networks that all workloads use. However, this is not a standard network connection but instead a network socket, which provides security through separation. This is something like passing along the contents of mail pieces without their envelopes. Web gateways also enable redundancy, as multiple gateways can point to the same workload, and multiple workloads can serve the same set of gateways.

When we say the ThreeFold Grid scales limitlessly, this is one of the ways that’s true. Many nodes, many gateways, many applications, and many users can all fit into this model. Deployers can start with a single virtual machine and a single public IP like in the example I’ll use to wrap up this piece below, then ramp up to a globally distributed and highly redundant system as their requirements grow.

🔗Send, receive, complete

Now we’ve seen how the ThreeFold Grid handles networking. From private and secure communication between workloads, to next generation peer-to-peer communication and full compatibility with the existing Internet, these offerings are comprehensive. Not only that, but they can be pretty darn fun to play with too.

In my own recent experience, I deployed a virtual machine on the Grid with a public IP and hosted a simple website with a map of nodes on the Grid that I’d been working on. I was able to quickly share it with some colleagues and members of the community. It went from a project I was tinkering with on my own computer to a live site on the Internet in a matter of minutes, thanks especially to the networking features of the ThreeFold Grid.

For the final piece of this series, we’ll see how everything comes together to turn computer code into a meaningful digital experience. Stay tuned!
