Last week we brought you an update surrounding the hackathons we’ve recently been involved in. Today, we’ll take a look at some of the awesome things that the Ethereum community have been building on the permaweb. Check back tomorrow for an overview of the web apps we built during our own internal hackathon!


ClaimIt is a tool produced at the ETHParis hackathon for making and managing claims on the Ethereum blockchain. Building on the wider Ethereum community’s work with ERC 725 and ERC 735, ClaimIt provides (in the developers own words) ‘easy-to-deploy dev tool to monitor and interact with standardized claim systems’. As well as providing the developer tools needed to work with the growing on-chain claims infrastructure, ClaimIt also provides a simple and user-friendly web application (hosted on the Arweave) for managing these claims, complete with push notifications and live UI updates. Neat! As mentioned in our previous blog post, we are very excited about this user case of storing the web apps associated with smart contract systems on the Arweave’s permaweb — making the UIs people need to interact with the systems as permanent as the systems themselves.

KiwEth is a Docker configuration generator for simply building and destroying test Quorum blockchains. The web app offers the user a simple set of options for configuring the blockchain deployment in such a way that it is easy for developers who are new to blockchain to get up and running. As the developers of KiwEth correctly identified, easily building and deploying test blockchains is still a major issue for those getting started with blockchain development. KiwEth addresses this by offering a simple step-by-step interface for building dockerized blockchain environments quickly and simply. KiwEth also uses Arweave’s web application hosting features to serve the web pages that make up the ‘wizard’ UI that produces the Docker images.

As the generator requires access to private configuration data, KiwEth makes use of Arweave’s decentralised and trustless nature to ensure that once published and audited, the Arweave TXID that relates to the web app will always return a safe web app that does not steal these details. That is, once published, the author cannot change the web app to send the private data to a server, add intrusive ads, or change the offering. This hints at a powerful feature of permaweb apps: consumer integrity. We are excited to share some more of our thoughts about this in an upcoming blog post!

On-going: NuCypher virtual hackathon

After ETHParis, we were very excited to join NuCypher’s tech stack for their on-going virtual hackathon! NuCypher is a proxy re-encryption scheme for building a privacy infrastructure for data handling in decentralised applications. If you want to get involved with the community and get hacking an Arweave+NuCypher app, why not check it out here. They have a generous grand prize on offer, too!

Here is a workshop we recently gave for the NuCypher hackathon explaining how to get started with Arweave web app development for dApps:

Remember to check back tomorrow for more showcases of some of the apps living on the permaweb!

A novel data storage blockchain protocol enabling a permanent serverless web and creating truly permanent data storage for the first time.
