Node v.10.6.2 is live, featuring structural enhancements and preparing the network for the version 11 hard fork. The ledger team progressed with nested transactions and account address improvements, while Hydra v.1.3 focuses on production adoption. Coinbase now accepts ada as loan collateral, and the Leios prototype successfully minted endorser blocks under load. Finally, Messari released the Q4 2025 report alongside Intersect's committee election announcement.

Node v.10.5.4 has been released, introducing critical patches to enhance the robustness of the diffusion layer. The consensus team integrated network packages for the upcoming node v.10.7 and further advanced the Leios prototype. Meanwhile, the Mithril team implemented new succinct proofs and SNARK-friendly certificate chains. Simultaneously, the Leios team moved toward finalizing protocol parameter recommendations through extensive research and simulations to analyze network traffic under load.

The High Assurance team has launched an early access program for its automatic formal verification tool, inviting developers to help shape the future of smart contract security. In scaling updates, Mithril distribution 2603.1 is now available, featuring a decentralized message queue protocol and Blockfrost API integration. Furthermore, the IOG Research team officially closed Work Package 25 by submitting its comprehensive 2025 end-of-year reports to Intersect.

Yaci Store 2.0.0 is a high-performance Java-based indexer that introduces native ledger and governance state derivation, allowing applications to track proposals and calculate staking rewards directly from on-chain data. This update features a modular plugin framework supporting JavaScript and Python for custom processing. Operational enhancements like PostgreSQL range partitioning and Prometheus monitoring ensure the platform is scalable and production-ready for complex ada-based decentralized applications.

Cardano node v.10.7 development and Leios endorsement block prototyping are advancing, pushing the network toward higher throughput. The Hydra team focused on performance optimizations and a Raspberry Pi demo, while Mithril prepared distribution 2603.1-pre with DMQ protocol support. Furthermore, Intersect is coordinating an intra-era upgrade to protocol version 11, laying the groundwork for enhanced governance and scalability features.

The updated Cardano constitution has been ratified and officially took effect on January 24, marking a pivotal step in decentralized governance. The ledger team finalized the design for nested transactions (CIP-118) and began implementing account address enhancements (CIP-159) for the upcoming Dijkstra era. Simultaneously, the Mithril team focused on SNARK-friendly libraries and prepared the infrastructure for the decentralized message queue (DMQ) network deployment.

The final development report for 2025, dated December 12, highlights the approval of the Pyth Lazer oracle integration and Serviceplan Group joining Intersect as an enterprise member. The consensus team completed LSM-tree work, slated for integration in node v.10.7. Mithril made progress on its SNARK-friendly STM library and Bitcoin DeFi prover prototype. In governance, a critical vote is underway to restore the Constitutional Committee to full capacity, while Project Catalyst Fund15's community review period closes on December 15. The Midnight Redemption portal is live, and the NIGHT token is now trading on exchanges like Kraken.

The 2025 State of the Cardano Developer Ecosystem Survey reveals a shift in developer priorities, with Identity and Authentication now the primary focus for DApps, overtaking DeFi and stablecoins. Key findings from the 109 respondents include TypeScript, JavaScript, and Python as the top proficiency languages, while Aiken has become the dominant smart contract tool, used by over 75% of developers. The community identified Ouroboros Leios (higher throughput) and improved documentation as the ecosystem's most pressing technical needs.

The ledger team finalized the specifications for nested transactions, while Lace v.1.32 launched with a new notification center and NIGHT token support. Hydra v.1.2.0 introduced the "SafeClose" feature, and Mithril advanced its SNARK-friendly STM library. Additionally, Project Catalyst Fund15 moved into community review with 761 proposals, and a 23-hour virtual Annual Members' Meeting was successfully hosted.

Giorgio Zinetti analyzed the November 21 incident, where a malformed transaction caused a temporary chain partition. Despite the split, block production continued uninterrupted, and the network remained online throughout. A coordinated response from SPOs and the Ouroboros consensus mechanism resolved the issue within 14 hours, demonstrating the network's resilience and decentralization.
