Engineering Follows Protocol and Governance Into Decentralization Input Output Group (@IOGroup) is spinning out development of Cardano's Haskell node to community curation and control, closin
Input Output Group (@IOGroup) is spinning out development of Cardano's Haskell node to community curation and control, closing a handover process that began in 2024 and is expected to conclude in 2027. The move completes a sequence in which protocol design and on-chain governance were already distributed across the ecosystem, leaving engineering as the final piece.
CoinDesk reported that independent companies such as Se7en Labs and Teragone will assume responsibility for parts of the core infrastructure, while at least three Cardano implementations written in Haskell, Rust, and Go will be maintained under community oversight and formal specifications. Intersect and Pragma will supervise those formal specs, subject to community review and vote. Input Output will refocus its efforts on research and new ventures through IO Labs and IO Ventures.
Founder Charles Hoskinson (@IOHK_Charles) framed the restructuring as the final stage of the Voltaire era. "The last stage of the Voltaire era is full decentralization of node and reference blueprint development," he said. He described the ecosystem's current metrics, including $ADA trading near 16 cents and total value locked at $70 million, as growing pains rather than structural failures.
The announcement arrives alongside a significant governance milestone. The van Rossem hard fork, which advances Cardano to Protocol Version 11, was ratified on July 13 through the network's Voltaire on-chain governance framework. According to Intersect, DReps approved the action with 77.63% support against a 60% threshold, while SPOs cleared their 51% bar at 52.7%, and six of seven Constitutional Committee members voted in favour. Enactment is scheduled for July 18, 2026 at 21:45 UTC.
This is the first Cardano hard fork that was not orchestrated top-down by founding entities. Instead, it was initiated, debated, and ratified entirely through decentralized governance. Protocol Version 11 brings enhanced Plutus smart contract performance, reduced execution costs, new cryptographic primitives to support zero-knowledge proof verification, and enforced VRF key uniqueness. The upgrade also lays technical groundwork for Leios, a later scaling initiative targeting a significant increase in transaction throughput.
The broader picture reflects a deliberate contraction of Input Output's footprint. IO has reduced its treasury funding request by nearly 50% from the prior year, with the stated aim of asking for progressively less as specialist partners absorb more of the work.
