This deliverable outlines the high-level requirements for an innovative contract stack for the OASEES. OASEES leverages decentralized infrastructure incorporating swarm intelligence, distributed ledger technology, and blockchain for secure data exchange and collaboration. The resulting OASEES architecture comprises multiple layers, with the Distributed Secure Swarm Layer, in which Decentralized Autonomous Organizations (DAOs) are defined. DAOs combine DApps involving smart contracts to enable trust in swarm environments. The DAO, equipped with Human-in-the-Loop (HITL) mechanisms, facilitates resource management, incentives, and decision-making for swarm collaboration. Users interact with the DAO through digital wallets, token staking, voting on proposals, and receiving rewards.
