We get it, #blockchain-speak can be quite the impenetrable code when you’re just starting out
That’s why we’ve put together a selection of key terms from our glossary, so if you’re a newcomer – or if you just need to brush up on vocab – you can navigate #Web3 like a pro @Cardano
Discover the backstory behind the name of the #Cardano native currency, $ada.
A few clues: she was the daughter of a famous poet, a famous mathematician, and arguably the first programmer.

Named after the biblical Tower of Babel – or perhaps Douglas Adams’s fish – this mechanism doesn’t help you speak every language, but it will open up interoperability with other digital currencies for #Cardano.
This term refers to a function that means you always know exactly how much a transaction will cost before you make it on the Cardano #blockchain.
This is one to remember: the accounting model used by #Cardano which extends the model used by Bitcoin and which makes the #blockchain super secure, scalable, and makes fees predictable.
At IOG we use formal mathematical methods as the basis for our rigorous research and checks.

Power to the people. Decentralization is the ruling principle behind #Cardano and means no central authority controls its development. Find out who does.
Hydra. A nine-headed snake-like monster from ancient Greek mythology? Not quite. On #Cardano, Hydra refers to a branching of protocols to speed things up and keep network congestion low.

An initial stake pool offering is comparable to shares in a company. You delegate your stake to the pool, you get tokens back in return. Learn more below 👇
Jormungandr.
Potentially the hardest #Cardano term to pronounce. But don’t worry, knowing what it means doesn’t mean you have to actually say it out loud. Find out what it’s all about…
Lovelace. Ada’s surname and the namesake for the smallest units of #Cardano’s digital currency. Want more backstory? Check the post!
Named after Christopher Marlowe, this web-based platform opens up financial smart contracts on #Cardano to new types of builders. Read more about it.
Did you know you can create your own tokens on #Cardano? They act just like Cardano’s digital currency, ada, and they can be used for a variety of purposes. Find out more.
The ouroboros is an ancient symbol depicting a serpent or dragon eating its own tail. It’s often a symbol for eternal cyclic renewal.
In #Cardano terms Ouroboros refers to its groundbreaking consensus protocol. Find out more.
P is for #Plutus. Named after the ancient Greek god of wealth, this is the programming language used for smart contracts on #Cardano.
Check out the full deets.
Quantum computing. Sounds beyond smart, right? Well, it is. Find out (a little) more about it here. Don’t worry, you don’t have to be a quantum physicist to understand it…
Let’s keep it real. No, really. This concept is all about making a tangible difference to people’s lives. Finance for everyone, everywhere. Learn more⤵️
Stake pools. The collective delegations from you and other fellow ada holders are stored here, and in turn they can earn you rewards. Intrigued? Check the image for more info...
This one is all about sustainability and governance. The treasury is where a percentage of rewards are collected to fund #Cardano. More info in the image 👇.
U is for UTXO. This one is all about the accounting model used by #Cardano (and #Bitcoin too). Read more about it.

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?
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.
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. 🛡️

The age of Voltaire brings on-chain governance to Cardano! The community, along with DReps, SPOs, and committees, are now stewards for Cardano's development, guided by the constitution.
Informed and active participation is key to shaping Cardano's future. Discover 10 useful resources that help drive transparent and inclusive governance! 🧵

A New Dawn
A curated hub highlighting Cardano governance. A New Dawn offers educational content on delegation, participation, and viewing proposed enhancements while spotlighting ecosystem builders.
A platform for budget reconciliation polling, Ekklesia helps DReps support treasury proposals. It has been key to the 2025 budgeting process, encouraging early, transparent coordination.
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.
3/7
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.
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.
