In traditional rental processes, contract notarization often takes days, involving the transfer of paper documents, queuing at the notary office, and high service fees. The Sign Protocol compresses this process to 10 seconds while achieving unprecedented transparency and security. For example, the Sign Protocol solution is fundamentally reconstructing the trust mechanism in this field.
10-second certification: A revolutionary process from complex to extremely simple
Traditional rental notarization usually requires tenants and landlords to go to the notary office together, submit identification, property certificates, and pay hundreds of yuan in fees, taking 3-5 business days. The Sign Protocol solution only requires three steps:
On-chain Identity Verification: Landlords and tenants complete real-name authentication through SignPass, and the system automatically verifies on-chain identity credentials (such as UAE government-issued digital passports or identity information from the Chinese Ministry of Public Security), eliminating the need to repeatedly submit paper materials.
Smart Contract Generation: The platform calls standardized templates from the Sign Protocol, automatically filling in key content such as property information and rental terms. Tenants can confirm the terms by signing with their wallet, without any human intervention throughout the process.
On-chain Evidence and Notarization: After the contract is signed, its hash value is instantly recorded on-chain, and an immutable notarization record is generated using zero-knowledge proof technology (zkAttestation), taking only 10 seconds.
Transparency and Security: The inherent advantages of blockchain
The Sign Protocol solution addresses not only efficiency but also three major pain points of traditional notarization:
Tamper-proof: Contract content and signing records are permanently stored on decentralized storage networks like Arweave, and any modifications will leave an on-chain trace, eliminating the risk of landlords or tenants altering terms afterward.
Traceability: Through the SignScan indexer, both parties can query the contract status in real-time (such as rental payment records and deposit refund status), with all operations being public and transparent.
Legal Compliance: The certification layer of the Sign Protocol meets the requirements of the Electronic Signature Law, and its on-chain evidence has been recognized by judicial institutions in multiple countries including China and the UAE, and can be used directly as litigation evidence.
Ecological Collaboration: From contracts to community governance
The rental solution of the Sign Protocol is not an isolated function but part of its 'full-chain certification ecosystem.' For example:
TokenTable Integration: Rental payments can be automatically executed through smart contracts, and overdue payments will trigger deposit deduction clauses, reducing disputes.
DAO Governance Extension: Tenants and landlords can participate in community voting based on the on-chain contract, such as voting on proposals for the use of property maintenance funds, forming a closed-loop governance.
Future Outlook: As the collaboration between Sign and countries like Sierra Leone deepens, on-chain rental certification may become the standard process for cross-border leasing. This 'code as notarization' model not only redefines the boundary of efficiency but also makes trust a programmable underlying infrastructure.
