Native tokens in the extended UTXO model

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

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…
