On-chain credentials.
A six-month, six-season hackathon programme. Builders ship real projects to OPN Chain. The chain verifies the work, the IOPn team verifies the quality, and every builder who qualifies walks away with permanent on-chain credentials tied to their wallet.

Season themes
05/06
Six seasons. Six verticals.
Each season runs a different theme across its 45-day cycle. Season 6 is the Open Track, any build on OPN Chain qualifies regardless of category.
- S1
Season 1
DeFi & Open Finance
Permissionless financial protocols and open-access money systems. The vertical covers any infrastructure where the chain itself replaces a traditional financial intermediary, from low-level primitives up through consumer-facing products.
You are here
- S2
Season 2
Identity & Reputation
Cryptographic identity, verifiable credentials, and on-chain reputation. The vertical covers how individuals and organizations prove who they are, what they have done, and what they can be trusted with, without depending on a central authority.
- S3
Season 3
Real World Assets
Off-chain value brought on-chain. The vertical covers the full path from how real-world assets become digital, to how they are priced and made tradeable, to how on-chain settlement enforces their constraints.
- S4
Season 4
AI & Compute
AI workloads and decentralized compute running on OPN Chain. The vertical spans both the infrastructure that coordinates compute and data flow, and the AI applications built on top of that infrastructure.
- S5
Season 5
Gaming & Ownership
Player-owned games and digital ownership. The vertical covers in-game economies, asset systems, and the broader question of what real ownership of digital items looks like when settlement happens on-chain instead of inside a publisher's server.
- S6
Season 6
Open Track
Any product built on OPN Chain. If a build does not fit cleanly into one of the five themed verticals but uses OPN Chain infrastructure as a load-bearing part of the product, this is its hackathon.
