Input Output Group

Midnight will soon have the tech for a single private vault where all your assets across many blockchains can be represented and controlled in one place.

ICYMI: Every week, we bring together the latest from Input Output and the Cardano ecosystem – project updates, technical progress, and development reports straight from the teams building the protocol. Sign up for IO’s newsletter to stay informed! services.iog.io/developer-dige… In last week’s development report:

DRep voting for the 2026 Treasury proposals has now closed. Thank you to everyone who took the time to review proposals, join discussions, challenge assumptions, ask questions, and engage throughout the process. This is decentralized governance in action: open dialogue, transparent accountability, and collective decision-making at ecosystem scale. Thank you to the Cardano community for showing up and participating.

We can do this!! 💪 Who of you hasn't voted yet? I'm here to answer any questions you might have. Just make sure you vote before this closes in less than 4 hours!

Developers build ecosystems, and this proposal is about making Cardano one of the best places in crypto to build. By improving tooling, documentation, and developer experience, we can attract more builders, accelerate adoption, and empower the next generation of products and services on Cardano.

After reflecting deeply on this governance process, a few things are clearer to me than ever. Cardano is alive. The community is engaged. And that matters more than any single vote. But this process has shown me something important: Cardano's governance is real. You are not passive holders. You are owners. That is exactly what we built this for. It has also reminded me that when Cardano has needed it most, the Pentad delivered. IOG, EMURGO, the Cardano Foundation, Midnight Foundation, and Intersect have proven they can coordinate and bring critical integrations to life when the ecosystem needed it. That coordination layer matters now more than ever. So let me show up the way I should. I will be in Singapore for the Cardano Summit and I will be on stage. I am also personally committing to partially top up our Token2049 sponsorship to Title level. Being on that main stage is where Cardano and Midnight need to be heard. To the Pentad, I am inviting all of you to sit down and have a real conversation about the future of governance and how we formalise this coordination going forward. I am 100% focused on Cardano and Midnight. Always have been. Let me prove it. #strongertogether

Final hours before DRep voting closes. Over the last 5 weeks, IO has published full proposal breakdowns, delivery plans and milestones, FAQs, proposal rationale, open discussions with initiative leads, and the proposals that were rejected alongside the reasoning behind those decisions. The work is public and the decision now sits with the community. Review the proposals and cast your vote: momentum.cardano.iog.io

Plutus running ~1M scripts/month is evidence that the foundation works. And mature infrastructure is exactly where careful, targeted improvements matter most. Smart contract platforms across major ecosystems continue evolving as adoption grows. This proposal focuses on: • Estimated ~30% cost reductions • New primitives like Poseidon for ZK workloads • Property-based conformance testing to strengthen node diversity • Continuous security audits and further Agda formalization That’s how strong foundations stay strong.

Reliable infrastructure doesn’t happen by accident. Cardano maintenance keeps the network stable, secure, and continuously operational through ongoing work across the node, infrastructure, monitoring, testing, and core systems that the ecosystem depends on every single day. It’s the foundation that allows builders, applications, and the wider network to keep moving forward with confidence.

Plutus is the smart contract platform behind applications built on Cardano. This proposal focuses on enhancing: • efficiency and cost-effectiveness • security, reliability, and testing • readiness for the next generation of Cardano infrastructure • the developer experience and tooling It’s about making Cardano’s core smart contract layer more efficient, more secure, and more accessible for builders. As Cardano adoption grows, investing in the foundations matters. Plutus is one of those foundations. Read the proposal: momentum.cardano.iog.io/proposals/plut…

📷 Ensurable Systems is a co-delivery partner on the IO: Maintenance proposal. Here’s why we think DReps should vote Yes — and why it matters more than the headlines suggest.

Midnight lets banks, asset managers, and RWA issuers manage disclosure on-chain without exposing their data forever.

48 hours. 10 proposals, focused on performance, security and capability. This is the work that builds what Cardano needs to scale long-term. If you haven't read them yet, now is the time. DRep voting closes Sunday at 22:45 UK: momentum.cardano.iog.io

@Cardano_CF Please reconsider the NO vote on the Plutus proposal. After reading the rationale, I think several points misunderstand the scope and impact of the work: The proposed features are strictly additive. Existing languages and tooling can continue operating on the current Plutus version without immediate changes. This is not forced breakage for downstream compilers; a significant amount of engineering effort goes into preserving that compatibility. Most proposed builtins are performance-oriented. The community has consistently asked for cheaper execution, better script efficiency, and higher-throughput smart contracts. Several of these proposals also originate from community-driven CIP discussions, which reflects clear ecosystem demand for the capabilities these builtins provide. Plinth is not just “one language’s tooling.” It also serves as a reference implementation for Plutus. Improvements there help clarify semantics, surface edge cases, and provide guidance that other ecosystem tools can rely on. ZK builtins are not feature bloat. Without them, many ZK applications are either impossible or only feasible in a very limited form on Cardano. If we want Cardano to support serious zero-knowledge cryptographic applications, these builtins are necessary. Budget transparency and downstream coordination may be worth discussing, but they should not be conflated with the technical value of the proposal itself. This proposal strengthens the foundations of Plutus and expands what developers can realistically build on Cardano, which I believe is essential if Cardano is going to remain competitive with smart contract environments of other blockchains.

The Blockfrost Platform 1.0.0 is live 🥳 Cardano stake pools can now run it alongside their block-producing node, serving Blockfrost API traffic and earning ADA for what they handle. Here's what's new 👇

Leios prototype now diffuses votes over a dedicated mini-protocol, Lace is available on iOS, and Mithril's SNARK circuit work keeps advancing. Another week of steady delivery from IO teams – read the full update: essentialcardano.io/development-up…

Cardano Upgrades just crossed the DRep approval threshold. Upgrades include: 1. CIP-159 Account Address Enhancement 2. Multi-Asset Treasury CIP 3. Native Babel Fees

Great session with the team yesterday on the Cardano Upgrades proposal — three workstreams that unlock real utility: 1️⃣ Enhanced Account Addresses — semi-Ethereum-like accounts, opening the door to microfees and new use cases 2️⃣ Multi-Asset Treasury — project funding in stable currencies for better budgeting and planning 3️⃣ Babel Fees — bridge to Cardano and transact in your native currency, seamlessly Listen to the full session here 👇 @IOGroup

The community decides now. Voting closes on Sunday 22:45 UK time. Here's what IO's 2026 proposals are built on. voting.cardanofoundation.org

Babel Fees could bring 2.5M+ additional monthly transactions to Cardano. Pay fees in any token. Lower the barrier. Grow the chain. Vote for Cardano Upgrades 🗳️ iog.io/news/three-car… @IOGroup
