Serving Cloudflare Pages sites to the IPFS network

Four years ago, Cloudflare went Interplanetary by offering a gateway to the IPFS network. This meant that if you hosted content on IPFS, we offered to make it available to every user of the Internet through HTTPS and with Cloudflare protection. IPFS allows you to choose a storage provider you are comfortable with, while providing a standard interface for Cloudflare to serve this data.

Since then, businesses have new tools to streamline web development. Cloudflare Workers, Pages, and R2 are enabling developers to bring services online in a matter of minutes, with built-in scaling, security, and analytics.

Today, we're announcing we're bridging the two. We will make it possible for our customers to serve their sites on the IPFS network.

In this post, we'll learn how you will be able to build your website with Cloudflare Pages, and leverage the IPFS integration to make your content accessible and available across multiple providers.

A primer on IPFS

The InterPlanetary FileSystem (IPFS) is a peer-to-peer network for storing content on a distributed file system. It is composed of a set of computers called nodes that store and relay content using a common addressing system. In short, a set of participants Continue reading

Web3 — A vision for a decentralized web

By reading this, you are a participant of the web. It's amazing that we can write this blog and have it appear to you without operating a server or writing a line of code. In general, the web of today empowers us to participate more than we could at any point in the past.

Last year, we mentioned the next phase of the Internet would be always on, always secure, always private. Today, we dig into a similar trend for the web, referred to as Web3. In this blog we'll start to explain Web3 in the context of the web's evolution, and how Cloudflare might help to support it.

Going from Web 1.0 to Web 2.0

When Sir Tim Berners-Lee wrote his seminal 1989 document “Information Management: A Proposal”, he outlined a vision of the “web” as a network of information systems interconnected via hypertext links. It is often assimilated to the Internet, which is the computer network it operates on. Key practical requirements for this web included being able to access the network in a decentralized manner through remote machines and allowing systems to be linked together without requiring any central control or coordination.

How Cloudflare provides tools to help keep IPFS users safe

Cloudflare's journey with IPFS started in 2018 when we announced a public gateway for the distributed web. Since then, the number of infrastructure providers for the InterPlanetary FileSystem (IPFS) has grown and matured substantially. This is a huge benefit for users and application developers as they have the ability to choose their infrastructure providers.

Today, we’re excited to announce new secure filtering capabilities in IPFS. The Cloudflare IPFS module is a tool to protect users from threats like phishing and ransomware. We believe that other participants in the network should have the same ability. We are releasing that software as open source, for the benefit of the entire community.

Its code is available on github.com/cloudflare/go-ipfs. To understand how we built it and how to use it, read on.

A brief introduction on IPFS content retrieval

Before we get to understand how IPFS filtering works, we need to dive a little deeper into the operation of an IPFS node.

Humanity wastes about 500 years per day on CAPTCHAs. It’s time to end this madness

Select all the buses. Click on bikes. Does this photo have traffic lights? As ridiculous as these questions are, you’re almost guaranteed to have seen one recently. They are a way for online services to separate humans from bots, and they’re called CAPTCHAs. CAPTCHAs strengthen the security of online services. But while they do that, there’s a very real cost associated with them.

Based on our data, it takes a user on average 32 seconds to complete a CAPTCHA challenge. There are 4.6 billion global Internet users. We assume a typical Internet user sees approximately one CAPTCHA every 10 days.

This very simple back of the envelope math equates to somewhere in the order of 500 human years wasted every single day — just for us to prove our humanity.

Today, we are launching an experiment to end this madness. We want to get rid of CAPTCHAs completely. The idea is rather simple: a real human should be able to touch or look at their device to prove they are human, without revealing their identity. We want you to be able to prove that you are human without revealing which human you are! You may ask if this is Continue reading

A Name Resolver for the Distributed Web

The Domain Name System (DNS) matches names to resources. Instead of typing 104.18.26.46 to access the Cloudflare Blog, you type blog.cloudflare.com and, using DNS, the domain name resolves to 104.18.26.46, the Cloudflare Blog IP address.

Similarly, distributed systems such as Ethereum and IPFS rely on a naming system to be usable. DNS could be used, but its resolvers’ attributes run contrary to properties valued in distributed Web (dWeb) systems. Namely, dWeb resolvers ideally provide (i) locally verifiable data, (ii) built-in history, and (iii) have no single trust anchor.

At Cloudflare Research, we have been exploring alternative ways to resolve queries to responses that align with these attributes. We are proud to announce a new resolver for the Distributed Web, where IPFS content indexed by the Ethereum Name Service (ENS) can be accessed.

To discover how it has been built, and how you can use it today, read on.
