Essential Cardano360 - December 2025 Edition

Welcome to the December edition of Essential Cardano360 - your monthly look at the people, progress, and projects shaping Cardano.

This month, we’re doing things a little differently. Instead of our usual roundup, as we head towards an exciting 2026, we look back at some of the defining moments that made 2025 such a standout for the ecosystem.

It’s been a year of historic milestones. We recap on an intense year for governance, from the foundations of decentralized decision-making to what the future holds as governance continues to evolve and mature.

We also look back at some of the engineering breakthroughs – from Hydra to the launch of the Leios Development Tracker, bringing radical transparency to Cardano’s scaling roadmap.

And we celebrate you, the community that showed up in force around the globe, alongside the builders delivering real-world utility on-chain.
