Cardano Decentralization Accelerates as IOG Hands Core Infrastructure to External Developers
The multi-year transition marks the final phase of the Voltaire era, transferring control of the Haskell node, Plutus, and Hydra to independent teams.
Input Output Global (IOG), the primary development firm behind the Cardano blockchain, announced on Friday a sweeping plan to hand over control of its core software infrastructure to independent development teams. The transition, scheduled to begin in August and extend into 2027, represents a major milestone in Cardano’s long-term roadmap to eliminate single points of failure and reduce the network’s reliance on its founding entity.
The handover marks a critical transition in Cardano’s final developmental phase, known as the Voltaire era. While previous eras established the network’s foundation, enabled smart contracts, and introduced scaling solutions, Voltaire is entirely focused on decentralized governance and self-sustainability. Having already transitioned protocol decision-making and on-chain governance to the community, Cardano is now addressing the decentralization of its technical development pipeline.
Under the new initiative, IOG will transfer stewardship of several foundational components of the Cardano ecosystem. These include the Haskell node—the core software that runs the network—along with the Plutus smart-contract platform, the Daedalus wallet, Hydra scaling technology, and developer relations.
To manage these critical systems, IOG has tapped specialized external development firms. Among them is Se7en Labs, a development agency specializing in Solana blockchain infrastructure, bringing cross-chain expertise to the Cardano ecosystem. Another key partner is Teragone, a specialist software development and cryptographic research team that leads the development of Mithril, a stake-based signature protocol for the Cardano blockchain designed to boost bootstrapping speed and security for light clients.
“The last stage of the Voltaire era is full decentralization of node and reference blueprint development,” Input Output CEO and Cardano founder Charles Hoskinson said in the statement.
By distributing these responsibilities, Cardano joins a select group of layer-1 blockchains attempting to transition from a single-vendor development model to a multi-entity, open-source framework. Historically, blockchains like Ethereum have benefited from having multiple independent client implementations and development teams, which enhances network resilience against software bugs and centralized influence.
The phased transition starting in August is designed to ensure a seamless handoff without disrupting network operations. Over the next three years, these external teams will assume full responsibility for maintaining, upgrading, and expanding Cardano’s core stack, fulfilling the network’s ultimate promise of becoming a fully decentralized, community-driven public ledger.
