📢 Workshops in Rare Evo week

We’ve made remarkable progress in Cardano’s first year as a fully decentralized ecosystem.
We always knew this journey would be challenging. As a community, we’ve moved fast, and yes, too fast for some. Missteps and bumps in the road were inevitable. And yes, even the odd pivot.

But zooming out, we’ve come a very long way in a short time. All thanks to the engagement, commitment and grind from so many across the ecosystem. Now, at the midpoint of the year, it’s time to pause, reflect, and recalibrate. 🧵
1/5

As a prequel to Rare’s Governance & Dev Day, Input | Output will be sponsoring two days of focused reflection and forward thinking — to assess the governance journey so far and start to align on what comes next.

This additional workshop event over 5th & 6th August is an opportunity for community leaders and builders to come together and ask big questions, like:

❓How can we improve both on-chain and off-chain budget/decision-making processes?
❓What new channels or working methods could help drive constructive debate and build consensus?
What other difficult conversations still need to be had — and how can we have them constructively?
❓How do we balance the need for fiscal responsibility with bold, confident investment in the ecosystem?
❓Where should we focus our energy and funding to help Cardano grow into 2026?

2/5

By bringing together a representative cross section of DReps and other stakeholders from across our decentralized ecosystem, these two days aim to:

🔎Capture an after action review (AAR) that details constructive, actionable feedback from the diverse perspectives of all stakeholders on the 2025 budget process. And start to shape a more efficient, more refined version for 2026.

⚖️Identify and align on the key governance and constitutional topics requiring clarification or amendment, feeding into a community-validated roadmap for proposed changes to the constitution in 2026.

⚙️Discuss the creation of an executive function for Cardano, including structure, accountability, and decision-making roles. How do we leverage the power of a decentralized community in a coherent, strategically aligned way?

But we want to shape the agenda together. We will be reaching out to community members over the week ahead and gathering feedback on what other topics should be discussed and included. So please drop us a comment below to let us know what you’d like to see included?

Cardano’s next chapter will be shaped by all of us.

In an ongoing series of threads, IO shares its proposed roadmap with the community, focusing on scalability, usability, and interoperability. These aren’t standalone ideas, but together, they help drive us towards a vision for where we take Cardano next.

Today we’re featuring 'New anti-grinding measure – Strengthening Cardano's consensus, hindering grinding attacks, and improving settlement times' 1/7🧵👇

Grinding attacks, where network leaders manipulate block additions for re-election advantages, pose a threat, and existing Ouroboros anti-grinding measures can impact settlement times. 2/7🧵

The anti-grinding feature, proposed as part of node improvements, focuses on improving Ouroboros by making grinding attacks harder for adversaries, with minimal overhead for honest participants. 🛡️

1/6: Mithril is a protocol for lightweight access to the Cardano blockchain.

By removing reliance on full nodes for synchronization, it streamlines blockchain verification while maintaining security.

2/6: Key beneficiaries:

- Light wallets and mobile applications
- Layer 2 solutions (bridges, rollups, state channels)
- Stake pool operators (node bootstrapping).

3/6: Mechanism: Mithril aggregates individual signatures from network participants into multi-signatures, creating compact certificates for trustless validation.

Cardano's EUTXO model brings determinism and predictability to blockchain! It builds on Bitcoin's UTXO but enhances it for smart contracts and complex apps without sacrificing security or simplicity.

So what does it mean?

1/7

@IOHK_Charles says EUTXO is ‘hand-in-glove built for isomorphism between the off-chain and on-chain.’

Essentially, equality between the two. This means what you see off-chain is what happens on-chain.

2/7

A Bitcoin wallet is like a jar holding coins (UTXOs). To spend $30, you'd use a $50 coin and get $20 change – a new UTXO. Cardano extends this by adding data and logic, creating more versatile UTXOs beyond simple value storage.

Cardano's sustainable future and competitiveness depends on research & innovation.

Today, Input | Output Research submitted its 'Cardano Vision - Work Program 2025' proposal to fund the foundational work required for long-term growth.

Here’s the focus 👇
1/6

The proposal covers:

🔬 20 Fundamental Research Streams (Ouroborous, Tokenomics, Hydra, Interchains & more)
💡 6 Technology Validation Streams (Leios, Minotaur, Jolteon Liveness, RSnarks, Anti-grinding etc.)

All aimed at scalability, sustainability & interoperability and defined through an evidence-based approach.
2/6

Execution will be led by the Input | Output Research team, the leading blockchain research network worldwide including more than 14 universities, who have published over 200 peer-reviewed papers involving more than 150 researchers.

This continues the foundational research that built Cardano.
