IPFS, the distributed file system and content addressing protocol, has been around since 2015, and Cloudflare has been a user and operator since 2018, when we began operating a public IPFS gateway. Today, we are announcing our plan to transition this gateway traffic to the IPFS Foundation’s gateway, maintained by the Interplanetary Shipyard (“Shipyard”) team, and discussing what it means for users and the future of IPFS gateways.

As announced in April 2024, many of the IPFS core developers and maintainers now work within a newly created, independent entity called Interplanetary Shipyard after transitioning from Protocol Labs, where IPFS was invented and incubated. By operating as a collective, ongoing maintenance and support of important protocols like IPFS are now even more community-owned and managed. We fully support this “exit to community” and are excited to support Shipyard as they build more great infrastructure for the open web.

On May 14th, 2024, we will begin to transition traffic that comes to Cloudflare’s public IPFS gateway to the IPFS Foundation’s gateway at ipfs.io or dweb.link. Cloudflare’s public IPFS gateway is just one of many – part of a distributed ecosystem that also includes Pinata, eth.limo, and many more. Visit the IPFS Public Gateway Checker to see the other publicly available IPFS gateways.

Cloudflare believes in helping build a better Internet for all and an accessible and private Internet, principles that Protocol Labs, IPFS, and Shipyard all share. We believe the IPFS gateway transition will boost ecosystem collaboration, increase protocol resiliency, and ensure healthy stewardship and governance. Cloudflare is proud to be a partner of the IPFS Project and Shipyard in this transition and will continue to help sponsor their work as gateway stewards.

All traffic using the cloudflare-ipfs.com or cf-ipfs.com hostname(s) will continue to work without interruption and be redirected to ipfs.io or dweb.link until August 14th, 2024, at which time the Cloudflare hostnames will no longer connect to IPFS and all users must switch the hostname they use to ipfs.io or dweb.link to ensure no service interruption takes place. If you are using either of the Cloudflare hostnames, please be sure to switch to one of the new ones as soon as possible ahead of the transition date to avoid any service interruptions!

It is important to Cloudflare, IPFS, and Shipyard that this transition is completed seamlessly and with as little impact to users as possible. With that in mind, there is no change to the amount or type of end user information that is visible to either Cloudflare, the IPFS Foundation, or Shipyard before or after the completion of this transition.

We’re excited to see further development and projects from the IPFS community and play our part in helping those applications be secure, performant, and reliable!

Interplanetary Shipyard is an engineering collective that delivers user agency through technical advancements in IPFS and libp2p. As the core maintainers of open source projects in the Interplanetary Stack (including IPFS and libp2p implementations such as Kubo, Rainbow, Boxo, Helia, and go-libp2p/js-libp2p), and supporting performance measurement tooling (Probelab), they are committed to open source innovation and building bridges between traditional web frameworks and the decentralized ecosystem. To achieve this, their engineers work alongside technical teams in web2 and web3 to promote adoption and drive practical applications.

Today we are excited to announce support for the Ethereum Merge on the Ethereum network and that our Ethereum gateways now support the Görli and Sepolia test networks (testnets). Sepolia and Görli testnets can be used to test and develop full decentralized applications (dapps) or test upgrades to be deployed on the mainnet Ethereum network. These testnets also use the Ethereum protocol, with the major difference that the Ether transacted on the testnet has no value.

Ethereum is a decentralized blockchain with smart contract functionality which Cloudflare allows you to interact with through an HTTP API. For a quick primer on Ethereum and our gateway, please refer to our previous blog post on the Ethereum Gateway.

As preparation for the merge, the Ethereum Foundation has executed merges on multiple testnets to ensure that the actual mainnet merge will occur with minimal to no disruption. These testnets both successfully upgraded to Proof of Stake and Proof of Authority, respectively. Cloudflare’s Testnet Gateway handled the Görli-Prater merge without issue, ensuring that we will be ready and prepared for the upcoming Ethereum Merge for mainnet. Our testnet gateways are live and ready for use by Cloudflare Ethereum Gateway customers.

In this blog, we are going to discuss the consensus transition entailed by the Ethereum Merge, changes in the Cloudflare Ethereum Gateway, and how you can start using them today.

Proof of Work is the original consensus mechanism of the Ethereum blockchain, popularized by Bitcoin. Miners compete to be the first to solve the puzzle, allowing them to update the blockchain with the latest transactions and receive a reward in exchange. The more miners and more processing power focused on solving these puzzles, the more secure the network. While this was first thought to help decentralization as it could be run on commodity hardware, users started to run highly powerful computer hardware, like ASICs and GPUs, to solve these complex math puzzles. This means the security of the network comes with a massive tradeoff. This massive network of Ethereum miners consume more than 80 terawatt Hours per year – more than the country of Chile. Clearly, this is not a sustainable mechanism for consensus, especially as use of cryptocurrency and web3 technologies becomes more widespread.

Proof of Stake is a consensus mechanism that lets users that have staked a specified amount of cryptocurrency run nodes to propose and validate blocks and receive a cryptocurrency reward. These nodes, commonly referred to as validators, are responsible for keeping the network secured and progressing. For every slot, one random validator node is chosen to be the proposer and a committee of random validator nodes is chosen to validate the proposed block. In the case of validators acting dishonestly or being unavailable, the validator will be penalized economically by having their stake “slashed”. Proof of Stake is significantly more sustainable – the Ethereum Foundation estimates that it will consume 99.95% less electricity than Proof of Work. Plus, it comes with the additional benefit that validators have a financial incentive to uphold the health of the blockchain.

Proof of Authority is very similar to Proof of Stake, as validators propose and validate blocks to progress their blockchain. However, a significant difference is that nodes can only become validators if they’re approved by an authority node, instead of putting up a stake. Cloudflare currently runs one such authority node for the now-deprecated Rinkeby testnet. This is a fairly uncommon consensus algorithm for public blockchains in comparison to Proof of Work and Proof of Stake, but is commonly used in trusted communities like internal networks for corporations and governments.

At Cloudflare, we believe in using our own technologies to build our products, and the Ethereum Gateway is no exception. The Ethereum Gateway allows any customer to interact with the Ethereum network without needing to run their own dedicated node. A JSON-RPC call is first received by a Worker, serverless code deployed in all of our data centers, ensuring that queries from any geographic region are processed quickly, and that requests are normalized using the latest block number known to the Worker.

The Worker then passes the call to a Cloudflare Load Balancer, corresponding to the specified Ethereum mainnet or testnet, which sends the call to Ethereum Node proxies inside our Kubernetes cluster. The Ethereum Node proxies queue calls and distributes them to ready and synced Ethereum Nodes that have the requested block. Our Ethereum nodes consist of an execution client and a consensus client.

The consensus client is responsible for Proof of Stake consensus, and we’ve added it to prepare the gateway for the merge. Ethereum Nodes then communicate with the specified Ethereum network to fulfill the RPC request. To ensure maximal speed, reliability, and availability, we have built in redundant Ethereum Node proxy instances and Ethereum Nodes in our cluster.

The Ethereum Merge is a long-awaited upgrade to the Ethereum network, changing the consensus method from the current and wasteful Proof of Work protocol to a more efficient Proof of Stake protocol. The merge also opens up the door for further developments to the Ethereum network, such as sharding, which promises to speed up transactions and lower costs.

The Ethereum Merge combines the current Ethereum Blockchain with the Ethereum Beaconchain, a Proof of Stake chain, when the Terminal Total Difficulty (TTD) is hit. Once the merge is completed, the Ethereum Beaconchain will be where consensus clients will communicate to propose and validate blocks. The existing blockchain will merge with the beaconchain, linking every block after the merge to a slot on the beaconchain. The blockchain will continue to handle Ethereum transactions and smart contracts.

To prepare for the merge, a node operator must deploy a consensus client like Prysm or Lighthouse alongside their execution client. If this doesn’t occur prior to the merge, their node’s copy of the blockchain will stop syncing and the execution client will be stuck on the last block prior to the merge.

As per our Ethereum gateway documentation, we have made it extremely easy to send JSON-RPC calls to your preferred testnet. After you have created your Ethereum gateway, change the network in the URL from mainnet to sepolia or goerli. For example, calling eth_blockNumber to the sepolia testnet for this example gateway will look like this:

$ curl -X POST -H "Content-Type: application/json" --data '{"jsonrpc": "2.0", "method": "net_version", "params": [], "id": 35}'  https://web3-trial.cloudflare-eth.com/v1/sepolia
{"jsonrpc":"2.0","result":"11155111","id":35}

This testnet support will help you ensure that your changes can be easily tested and hardened before deploying to the Ethereum Mainnet without incurring additional risk to your brand trust or product availability, all while not having to worry about operating your own infrastructure.

We want to ensure that anyone leveraging our Ethereum Gateway is able to achieve confidence and trust that whatever changes are pushed forward do not impact the end user experience. At the end of the day, the Internet is for end users and their experience and perception must always be kept within our purview at all times.

As part of this announcement, we will be deprecating our Rinkeby signer with public address 0xf10326c1c6884b094e03d616cc8c7b920e3f73e0, which we operated to support the Ethereum ecosystem. We will stop Rinkeby testnet support on January 15, 2023, following the Ethereum Foundation’s move to deprecate the Rinkeby testnet.

A little under four years ago we announced Cloudflare's first experiments in web3 with our gateway to the InterPlanetary File System (IPFS). Three years ago we announced our experimental Ethereum Gateway. At Cloudflare, we often take experimental bets on the future of the Internet to help new technologies gain maturity and stability and for us to gain deep understanding of them.

Four years after our initial experiments in web3, it’s time to launch our next series of experiments to help advance the state of the art. These experiments are focused on finding new ways to help solve the scale and environmental challenges that face blockchain technologies today. Over the last two years there has been a rapid increase in the use of the underlying technologies that power web3. This growth has been a catalyst for a generation of startups; and yet it has also had negative externalities.

At Cloudflare, we are committed to helping to build a better Internet. That commitment balances technology and impact. The impact of certain older blockchain technologies on the environment has been challenging. The Proof of Work (PoW) consensus systems that secure many blockchains were instrumental in the bootstrapping of the web3 ecosystem. However, these systems do not scale well with the usage rates we see today. Proof of Work networks rely on complex cryptographic functions to create consensus and prevent attacks. Every node on the network is in a race to find a solution to this cryptographic problem. This cryptographic function is called a hash function. A hash function takes a number in x, and gives a number out y. If you know x, it's easy to compute y. However, given y, it's prohibitively costly to find a matching x. Miners have to find an x that would output a y with certain properties, such as 10 leading zero. Even with advanced chips, this is costly and heavily based on chance.

While that process is incredibly secure because of the vast amount of hashing that occurs, Proof of Work networks are wasteful. This waste is driven by the fact that Proof of Work consensus mechanisms are electricity-intensive. In a PoW ecosystem, energy consumption scales directly with usage. So, for example, when web3 took off in 2020, the Bitcoin network started to consume the same amount of electricity as Switzerland (according to Cambridge Bitcoin Electricity Consumption Index).

This inefficiency in resource use is by design to make it difficult for any single actor to threaten the security of the blockchain, and for the majority of the last decade, while use was low, this inefficiency was an acceptable trade off.

As recently as two years ago, web3 was an up-and-coming ecosystem with minimal traffic compared to the majority of the traffic on the Internet. The last two years changed the web3 use landscape. Traffic to the Bitcoin and the Ethereum networks has exploded. Technologies like Smart Contracts that power DeFi, NFTs, and DAOs have started to become commonplace in the developer community (and in the Twitter lexicon). The next generation of blockchains like Flow, Avalanche, Solana, as well as Polygon are being developed and adopted by major companies like Meta.

In order to balance our commitment to the environment and to help build a better Internet, it is clear to us that we should launch new experiments to help find a path forward. A path that balances the clear need to drastically reduce the energy consumption of web3 technologies and the capability to scale the web3 networks by orders of magnitude if the need arises to support increased user adoption over the next five years. How do we do that? We believe that the next generation of consensus protocols is likely to be based on Proof of Stake and Proof of Spacetime consensus mechanisms.

Today, we are excited to announce the start of our experiments for the next generation of web3 networks that are embracing Proof of Stake; beginning with Ethereum. Over the next few months, Cloudflare will launch, and fully stake, Ethereum validator nodes on the Cloudflare global network as the community approaches its transition from Proof of Work to Proof of Stake with “The Merge.” These nodes will serve as a testing ground for research on energy efficiency, consistency management, and network speed.

There is a lot in that paragraph so let’s break it down! The short version though is that Cloudflare is going to participate in the research and development of the core infrastructure that helps keep Ethereum secure, fast, as well as energy efficient for everyone.

Proof of Stake is a next-generation consensus protocol to secure blockchains. Unlike Proof of Work that relies on miners racing each other with increasingly complex cryptography to mine a block, Proof of Stake secures new transactions to the network through self-interest. Validator's nodes (people who verify new blocks for the chain) are required to put a significant asset up as collateral in a smart contract to prove that they will act in good faith. For instance, for Ethereum that is 32 ETH. Validator nodes that follow the network's rules earn rewards; validators that violate the rules will have portions of their stake taken away. Anyone can operate a validator node as long as they meet the stake requirement. This is key. Proof of Stake networks require lots and lots of validators nodes to validate and attest to new transactions. The more participants there are in the network, the harder it is for bad actors to launch a 51% attack to compromise the security of the blockchain.

To add new blocks to the Ethereum chain, once it shifts to Proof of Stake, validators are chosen at random to create new blocks (validate). Once they have a new block ready it is submitted to a committee of 128 other validators who act as attestors. They verify that the transactions included in the block are legitimate and that the block is not malicious. If the block is found to be valid, it is this attestation that is added to the blockchain. Critically, the validation and attestation process is not computationally complex. This reduction in complexity leads to significant energy efficiency improvements.

The energy required to operate a Proof of Stake validator node is magnitudes less than a Proof of Work miner. Early estimates from the Ethereum Foundation estimate that the entire Ethereum network could use as little as 2.6 megawatts of power. Put another way, Ethereum will use 99.5% less energy post merge than today.

We are going to support the development and deployment of Ethereum by running Proof of Stake validator nodes on our network. For the Ethereum ecosystem, running validator nodes on our network allows us to offer even more geographic decentralization in places like EMEA, LATAM, and APJC while also adding infrastructure decentralization to the network. This helps keep the network secure, outage resistant, and closer to the goal of global decentralization for everyone. For us, It’s a commitment to helping research and experiment with scaling the next generation of blockchain networks that could be a key part of the story of the Internet. Running blockchain technology at scale is incredibly difficult, and Proof of Stake systems have their own unique requirements that will take time to understand and improve. Part of this experimentation though is a commitment. As part of our experiments Cloudflare has not and will not run our own Proof of Work infrastructure on our network.

Finally, what is “The Merge”? The Merge is the planned combination of the Ethereum Mainnet (the chain you interact with today when you make an Eth transaction) and the Ethereum Beacon Chain. The Beacon chain is the Proof of Stake blockchain running in parallel with the Ethereum Mainnet. The Merge is much more significant than a consensus update.

Consensus updates have happened multiple times already on Ethereum. This could be because of a vulnerability, or the need to introduce new features. The Merge is different in a way that it cannot be made by a normal upgrade. Previous forks have been enabled at a specific block number. This means that if you mine enough blocks, the new consensus rules apply automatically. With the Merge, there should only be one state root for the fork to happen. The merge state root would be the start of the Ethereum Mainnet PoS journey. It is chosen and set at a certain difficulty, instead of block height, to avoid merging a high block with low difficulty.

Once The Merge occurs later this year in 2022, Ethereum will be a full Proof of Stake ecosystem that no longer relies on Proof of Work.

This is just the start of our commitment to help build the next generation of web3 networks. We are excited to work with our partners across the cryptography, web3, and infrastructure communities to help create the next generation of blockchain ecosystems that are environmentally sustainable, secure, and blazing fast.

Today we are excited to announce that our Ethereum and IPFS gateways are publicly available to all Cloudflare customers for the first time. Since our announcement of our private beta last September the interest in our Eth and IPFS gateways has been overwhelming. We are humbled by the demand for these tools, and we are excited to get them into as many developers' hands as possible. Starting today, any Cloudflare customer can log into the dashboard and configure a zone for Ethereum, IPFS, or both!

Over the last eight months of the private beta, we’ve been busy working to fully operationalize the gateways to ensure they meet the needs of our customers!

First, we have created a new API with end-to-end managed hostname deployment. This ensures the creation and management of gateways as you continue to scale remains extremely quick and easy! It is paramount to give time and focus back to developers to focus on your core product and services and leave the infrastructural components to us!

Second, we’ve added a brand new UI bringing web3 to Cloudflare's zone-level dashboard. Now, regardless of the workflow you are used to, we have parity between our UI and API to ensure we fit into your existing processes and no time is wasted internally to have to figure out ‘how we integrate’, but rather, a quick setup and start to serve content or connect your services!

Third, we are pleased to say that you will soon have testnet support to ensure your new development can be easily tested, hardened, and deployed to your mainnet without incurring additional risk to your brand trust, product availability, or concern that something may fail silently and begin a cascade of problems throughout your network. We want to ensure that anyone leveraging our web3 gateways is able to achieve more confidence and trust that whatever changes are pushed forward do not impact end user experience. At the end of the day, the Internet is for end users and their experience and perception must always be kept within our purview at all times.

Lastly, Cloudflare loves to build on top of Cloudflare. This helps us stay resilient and also shows our commitment and belief in all the products we create! We have always used our SSL for SaaS and Workers products in the background. Building on our own services gives our customers the ability to define and control their own HTTP features on top of traffic destined for web3 gateways, including: rate limits, WAF rules, custom security filters, serving video, customer defined Workers logic, custom redirects and more!

Today thousands of different individuals, companies, and DAO's are building new products leveraging our web3 gateways -- the most reliable web3 infrastructure with the largest network

Here are just a few snippets of how people are already using our web3 Gateways, and we can’t wait to see what you build on them:

• DeFi DAO’s use the Cloudflare IPFS gateway to serve their front end web applications globally without latency or cache penalties.

• NFT designers use the Ethereum Gateway to effortlessly drop new offerings, and the IPFS gateway to store them in a fully decentralized system.

• Large Dapp developers trust us to handle huge traffic spikes quickly and efficiently, without rate limits or overage caps. They combine all our offerings into a single pane of glass so that they don’t have to juggle multiple systems.

As part of this announcement, we will begin migrating our existing users away from the legacy gateway endpoints and onto our new API, which is easier, highly managed, and more robust. To ensure a smooth transition, you will first need to make sure you have signed up for a Cloudflare account if you did not already have one. On top of that, we have made sure to keep our free users in mind and thus our free users will continue to use the gateways at no cost with our free tier option! This includes no cap in the amount of traffic that can be pushed through our gateways along with offering the most transparent and forecastable pricing models in the market today. We are very excited about the future and look forward to sharing the next iterations of web3 at Cloudflare!

Also, if you can’t wait to start building on our gateways, check out our product documentation for more guidance.

It’s cliché to say that the Internet has undergone massive changes in the last five years. New technologies like distributed ledgers, NFTs, and cross-platform metaverses have become all the rage. Unless you happen to hang out with the Web3 community in Hong Kong, San Francisco, and London, these technologies have a high barrier to entry for the average developer. You have to understand how to run distributed nodes, set up esoteric developer environments, and keep up with the latest chains just to get your app to run. That stops today. Today you can sign up for the private beta of our Web3 product suite starting with our Ethereum and IPFS gateway.

Before we go any further, a brief introduction to blockchain (Ethereum in our example) and the InterPlanetary FileSystem (IPFS). In a Web3 setting, you can think of Ethereum as the compute layer, and IPFS as the storage layer. By leveraging decentralised ledger technology, Ethereum provides verifiable decentralised computation. Publicly available binaries, called "smart contracts", can be instantiated by users to perform operations on an immutable set of records. This set of records is the state of the blockchain. It has to be maintained by every node on the network, so they can verify, and participate in the computation. Performing operations on a lot of data is therefore expensive. A common pattern is to use IPFS as an external storage solution. IPFS is a peer-to-peer network for storing content on a distributed file system. Content is identified by its hash, making it inexpensive to reference from a blockchain context.

If you want an even deeper understanding of how Web3 works check out our other blog posts on what is Web3 and creating Web3 Dapps with Cloudflare Workers.

Over the last four years, while we have been working to mature the technology required to provide access to Web3 services at a global scale, the idea of the Metaverse has come back into vogue. Popularized by novels like “Snowcrash,” and "Ready Player One," the idea is a simple one. Imagine an Internet where you can hop into an app and have access to all of your favorite digital goods available for you to use regardless of where you purchased them. You could sell your work on social media without granting them a worldwide license, and the buyer could use it on their online game. The Metaverse is a place where copyright and ownership can be managed through NFTs (Non-Fungible Tokens) stored on IPFS, and accessed trustlessly through Ethereum. It is a place where everyday creators can easily monetize their content, and have it be used by everyone, regardless of platform, since content is not being stored in walled gardens but decentralised ecosystems with open standards.

This shifts the way users and content creators think about the Internet. Questions like: “Do you actually need a Model View Controller system with a server to build an application?” “What is the best way to provide consistent naming of web resources across platforms?” “Do we actually need to keep our data locked behind another company's systems or can the end-user own their data?”. This builds different trust assumptions. Instead of trusting a single company because they are the only one to have your users' data, trust is being built leveraging a source verifiable by all participants. This can be people you physically interact with for messaging applications, X.509 certificates logged in a public Certificate Transparency Log for websites, or public keys that interact with blockchains for distributed applications.

It’s an exciting time. Unlike the emergence of the Internet however, there are large established companies that want to control the shape and direction of Web3 and this Metaverse. We believe in a future of a decentralised and private web. An open, standards-based web independent of any one company or centralizing force. We believe that we can be one of the many technical platforms that supports Web3 and the growing Metaverse ecosystem. It’s why we are so excited to be announcing the private beta of our Ethereum and IPFS gateways. Technologies that are at the forefront of Web3 and its emerging Metaverse.

Time and time again over the last year we have been asked by our customers to support their exploration of Web3, and oftentimes their core product offering. At Cloudflare, we are committed to helping build a better Internet for everyone, regardless of their preferred tech stack. We want to be the pickaxes and shovels for everyone. We believe that Web3 and the Metaverse is not just an experiment, but an entirely new networking paradigm where many of the next multi-billion dollar businesses are going to be built. We believe that the first complete metaverse could be built entirely on Cloudflare today using systems like Ethereum, IPFS, RTC, R2 storage, and Workers. Maybe you will be the one to build it...

We are excited to be on this journey with our Web3 community members, and can’t wait to show you what else we have been working on.

A gateway is a computer that sits between clients (such as your browser or mobile device) and a number of other systems and helps translate traffic from one protocol to another, so the systems powering an application required to handle the request can do so properly. But there are different types of gateways that exist today.

You have probably heard mention of an API gateway, which is responsible for accepting API calls inbound to an application and aggregating the appropriate services to fulfill those requests and return a proper response to the end user. You utilize gateways every time you watch Netflix! Their company leverages an API gateway to ensure the hundreds of different devices that access their streaming service can receive a successful and proper response, allowing end users to watch their shows. Gateways are a critical component of how Web3 is being enabled for every end user on the planet.

Remember that Web3 or the distributed web is a set of technologies that enables hosting of content and web applications in a serverless manner by leveraging purely distributed systems and consensus protocols. Gateways let you use these applications in your browser without having to install plugins or run separate pieces of software called nodes. The distributed web community runs into the same problem of needing a stable, reliable, and resilient method to translate HTTP requests into the correct Web3 functions or protocols.

Today, we are introducing the Cloudflare Ethereum and IPFS Gateways to help Web3 developers do what they do best, develop applications, without having to worry about also running the infrastructure required to support Ethereum (Eth) or IPFS nodes.

Traditional web technologies such as HTTP have had decades to develop standards and best practices that make sites fast, secure, and available. These haven’t been developed on the distributed web side of the Internet, which focuses more on redundancy. We identified an opportunity to bring the optimizations and infrastructure of the web to the distributed web by building a gateway — a service that translates HTTP API calls to IPFS or Ethereum functions, while adding Cloudflare added-value services on the HTTP side. The ability for a customer to operate their entire network control layer with a single pane of glass using Cloudflare is huge. You can manage the DNS, Firewall, Load Balancing, Rate Limiting, Tunnels, and more for your marketing site, your distributed application (Dapp), and corporate security, all from one location.

For many of our customers, the existing solutions for Web3 gateway do not have a large enough network to handle the growing amount of requests within the Ethereum and IPFS networks, but more importantly do not have the degree of resilience and redundancy that businesses expect and require operating at scale. The idea of the distributed web is to do just that… stay distributed, so no single actor can control the overall market. Speed, security, and reliability are at the heart of what we do. We are excited to be part of the growing Web3 infrastructure community so that we can help Dapp developers have more choice, scalability, and reliability from their infrastructure providers.

A clear example of this is when existing gateways have an outage. With too few gateways to handle the traffic, the result of this outage is pre-process transactions falling behind the blockchain they are accessing, thus leading to increased latency for the transaction, potentially leading to it failing. Worse, when decentralised application (Dapp) developers use IPFS to power their front end, it can lead to their entire application falling over. Overall, this leads to massive amounts of frustration from businesses and end users alike — not being able to collect revenue for products or services, thus putting a portion of the business at a halt and breaking trust with end users who depend on the reliability of these services to manage their Web3 assets.

We found that there was a unique opportunity in a segment of the Web3 community that closely mirrored Cloudflare’s traditional customer base: the distributed web. This segment has some major usability issues that Cloudflare could help solve around reliability, performance, and caching. Cloudflare has an advantage that no other company in this space — and very few in the industry — have: a global network. For instance, content fetched through our IPFS Gateway can be cached near users, allowing download latency in the milliseconds. Compare this with up to seconds per asset using native IPFS. This speed enables services based on IPFS to go hybrid. Content can be served over the source decentralised protocols while browsers and tools are maturing to access them, and served to regular web users through a gateway like Cloudflare. We do provide a convenient, fast and secure option to browse this distributed content.

On Ethereum, users can be categorised in two ways. Application developers that operate smart contracts, and users that want to interact with the said contracts. While smart contracts operate autonomously based on their code, users have to fetch data and send transactions. As part of the chain, smart contracts do not have to worry about the network or a user interface to be online. This is why decentralised exchanges have had the ability to operate continuously across multiple interfaces without disruptions. Users on the other hand do need to know the state of the chain, and be able to interact with it. Application developers therefore have to require the users to run an Ethereum node, or can point them to use remote nodes through a standardised JSON RPC API. This is where Cloudflare comes in. Cloudflare Ethereum gateway relies on Ethereum nodes and provides a secure and fast interface to the Ethereum network. It allows application developers to leverage Ethereum in front-facing applications. The gateway can interact with any content part of the Ethereum chain. This includes NFT contracts, DeFi exchanges, or name services like ENS.

Since our alpha release to very early customers as research experiments, we’ve seen a staggering number of customers wanting to leverage the new gateway technology and benefit from the availability, resiliency, and caching benefits of Cloudflare’s network.

Our current alpha includes companies that have raised billions of dollars in venture capital, companies that power the decentralised finance ecosystem on Ethereum, and emerging metaverses that make use of NFT technology.

In fact, we have over 2,000 customers leveraging our IPFS gateway lending to over 275TB of traffic per month. For Ethereum, we have over 200 customers transacting over 13TB, including 1.6 billion requests per month. We’ve seen extremely stable results from these customers and fully expect to see these metrics continue to ramp up as we add more customers to use this new product.

We are now very happy to announce the opening of our private beta for both the Ethereum and IPFS gateways. Sign up to participate in the private beta and our team will reach out shortly to ensure you are set up!
