Depto is a platform that replaces traditional patent verification and storage procedures with a decentralized, community-driven approach. It uses blockchain technology to ensure the security and transparency of patent applications and their verification process. The platform consists of three smart contracts: the Depto contract, the Governor Contract, and the TimeLock contract.

• Patent applications are verified by DAO members and minted as NFTs to the applicants.
• DAO members are incentivized for verification and validation of patent applications.
• Anyone can raise false claims or inspection of patent proposals in the platform.
• Secure communication among DAO members using Huddle video conferencing SDK.
• Push notifications for updates on patent applications and verification process.
• Decentralized governance logic and proposals handled by the Governor Contract.
• Automated minting of ERC721 NFTs for verified patents.
• Deployed using Spheron on the mainnet.

• Built using Openzeppelin for smart contract development and governance.
• Modified Openzeppelin governance for access-based voting instead of token-based voting.
• Used ZondaxAPI contracts for fetching Deal Provider and Commitment data for SPs to claim rewards.
• Frontend built using NextJS and TailwindCSS.
• Interacts with smart contracts using ethers.js library.

1. Patent applicants apply for a patent through the platform.
2. A DAO member verifies the authenticity of the application and creates a patent document.
3. The DAO member creates a proposal with the patent document's raw CID.
4. The verified patent is voted on and validated by other DAO members.
5. The validated patent is stored as a storage deal by a Storage Provider (SP).
6. The SP claims his rewards and the patent NFT is minted to the patent applicant.

Governor Contract (DAO)
mapping(address=>bool) isDAOMember - Is checked true when a member is added to the DAO.
mapping(address=>uint256[]) userToPatentClaims - maps the user to all dealIDs created by the user.
proposePatent(payable)  - callable by anyone, even members of DAO. On call, a new patent request is created. Which will be verified and voted by the DAO. Mints a claim NFT to the proposer as a proof of application.
raiseFalsePatentClaim(payable) - callable by anyone. It checks the date of both claims… if not valid, rejects. On successful claim, the money is returned. Or else is retained by the DAO.
execute - callable by anyone. Executes the proposal
proposeNewMember - Callable only by members of the DAO. On successful vote, a new member is added to the DAO.
voteProposal - callable only by members of the DAO. Each vote has only 1 weight no matter how many tokens you hold.

listPatents - callable by anyone, lists DAO approved patents.
