We’re excited to announce another opportunity to get paid to learn the decent.land stack and build something amazing with the tooling we’ve built.

This hackathon focuses on Ark Protocol, and your imagination is the only limit for how far you can take it.

We welcome integrations with existing dApps as well as tooling built from scratch leveraging the multi-chain power of Ark.

Read below to find out more and learn how to get involved and win part of the $12,000 prize pool.

The Ark Protocol Hackathon

Ark is a multi-chain identity linking protocol.

It allows users to associate their Arweave address with addresses on another chain, making it possible, for example, for an Arweave dApp to have proof that an Arweave user holds a cryptopunk on Ethereum, voted on a DAO proposal on NEAR, or holds a given ENS name.

This is a 4-week hackathon focused on developing multichain dApps on Arweave using Ark Protocol.

We are looking for submissions which integrate Ark as a core identity layer to a new or existing dApp.

What Ark enables

Ark enables users to prove identity and asset ownership cross-chain. For example, a dApp that uses Ark as part of its authentication flow could be built on Arweave but make use of attestations of NFTs and DIDs on Ethereum, NEAR, and other supported chains.

It could be used to power token-gated groups, DAO voting, identity vouching, anti-sybil mechanisms, multichain social networks, and more.

What's been built on Ark

ar.page

A social explorer for holders of ANS (Arweave Name Service) domains -- here's an example. Linked with Ark, it shows cross-chain NFTs and activity from EVM chains for Arweave users.

• Live deploy

• Source code

POAP -> Arweave airdrop bridge

An app built to bridge POAP ownership to Arweave users. For example: a user scans a QR code for a POAP at an event; the POAP is an access ticket to an airdrop on Arweave; the user connects their xDAI (EVM, 0x) wallet to Ark protocol and can claim their airdrop.

• Live deploy

• Source code

1notif

An on-chain, multichain gasless notification protocol. The protocol consists of channels (smart contracts) deployed on Arweave via EXM. The SDK wraps Ark to make it possible for channel deployers to send notifications to any supported network.

• Announcement

• Source code

Reach out in the Discord with questions on how these work -- happy to help.

Ark quickstart documentation

Check the README for an overview. We also published JavaScript examples for dApp integration that should provide a quick way to add Ark as an authentication method and read data from the protocol. A broader description of Ark and its connected chains and protocols can be found here.
