The full programme calendar.
Each season runs a different theme across its 45-day cycle. Past winners are immortalised on-chain, the active season is live now, upcoming seasons are scheduled and locked.
Season 1
DeFi & Open Finance
Season 1
DeFi & Open Finance
OPN Swap · OPN Locker · PerpDex
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.
Season 2
Identity & Reputation
Season 2
Identity & Reputation
NeoID · Nexus NFT · REP System
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.
Season 3
Real World Assets
Season 3
Real World Assets
Mosaic · OPN Chain
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.
Season 4
AI & Compute
Season 4
AI & Compute
ATLAS · GPU Infrastructure
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.
Season 5
Gaming & Ownership
Season 5
Gaming & Ownership
OPN Studios
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.
Season 6
Open Track
Season 6
Open Track
Any OPN Chain infrastructure
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.
