Handshake, the blockchain purpose-built for decentralizing internet naming, takes center stage in a new, open-source initiative with Blink Labs and Andamio’s technical team: an interoperable DNS marketplace where Handshake top-level domains (TLDs) can issue and manage second-level domains on Cardano. In this design, domains live as native Cardano assets and are governed by smart contracts, bringing self-sovereign, censorship-resistant naming into the programmable heart of Cardano’s ecosystem. 
For Cardano, the upside is clear: human-readable, trustless identifiers that dApps, wallets, and DAOs can integrate without relying on legacy DNS authorities. For Handshake, the collaboration extends adoption by connecting its decentralized root and TLDs to a high-assurance smart-contract platform—unlocking new marketplace mechanics, ownership models, and identity flows.
The strengths are clear: decentralization, interoperability, and technical depth. But challenges remain—cross-chain integrations are complex, requiring careful attention to security, user experience, and long-term maintenance. Still, this project will set a precedent for how specialized blockchains can combine forces to deliver practical, decentralized infrastructure—backed by the high technical expertise of the Blink Labs and Andamio teams.
In short, Handshake leads with sovereign naming; Cardano amplifies it with programmable guarantees. Together, they move the web closer to open, verifiable, and user-owned identity.
