IOR outlines a research framework for SPOs
19 June 2025 8 mins read
Stake pool operators (SPOs) are the beating heart of Cardano — the network’s backbone on which the ecosystem expands. As we scale and grow, it’s essential that we support not just users, builders, and governance innovators, but also the SPOs who’ve helped carry the chain for half a decade.
As part of the Cardano 2025 Budget, Input | Output Research (IOR) joined the monthly SPOs…
Cardano node's evolution towards diversity and modular design
The Cardano network is moving towards a more diverse and modular node ecosystem design for improved stability and scalability
6 June 2025 6 mins read
As the Cardano ecosystem matures in 2025 and beyond, improving the core node software is one of several priorities for strengthening the network infrastructure. Introducing multiple, diverse node implementations – built by different teams and in different programming languages – can improve network resilience, reduce systemic risk, and better reflect the principles of…

What is Mithril
Mithril is Cardano’s solution for enabling secure, efficient, and lightweight interactions with the blockchain. By removing the need to download and verify the entire blockchain history, Mithril significantly reduces resource requirements and makes Cardano more accessible for use cases such as:
- Certification of account transactions/balances in browser-based light wallets (including mobile)
- Certification of transactions in layer 2 solutions (bridges…
Native tokens in the extended UTXO model
A brief recap on how Cardano handles native assets and why it matters
9 May 2025 5 mins read
Blockchain tokens can be used for many different purposes – for example, to send and receive payments, access services in decentralized applications (DApps), or store and transfer value. The utility of a token is determined by its use case, the market, or the community that issues or adopts it. Tokens can be:
- Fungible – identical and interchangeable, like reward points or units of the same currency
- Non-fungible (NFTs) – often representing unique items such as…
Cardano’s EUTXO model: bringing deterministic predictability to blockchain
Discover the simplicity, security, and power behind Cardano’s extended unspent transaction output (EUTXO) model
2 May 2025 3 mins read
Cardano builds on Bitcoin’s unspent transaction output (UTXO) model, enhancing it for smart contracts and complex applications without sacrificing security or simplicity. This advanced version, extended UTXO (EUTXO), offers significant benefits for developers and users.
In his recent video, Charles Hoskinson highlighted the model’s power:
‘When you look at EUTXO, it’s really hand…
