Smart Contracts, Oracles and Wrapped Assets

A problem though is that smart contracts only know what’s happening on the blockchain itself. There’s so way for […]

A UTxO is a passive thing, it just sits there until a transaction uses it. On-chain vs Off-chain On-chain is about validation Off-chain part […]
. (E)UTxO Model basics
The (E)UTxO model stands for “Extended Unspent Transaction Output” model. This is the counting model that Cardano uses UTxO is used by bitcoin (bitcoin does actually have smart contracts, they are just not very smart!). Cardano extends the UTxO model, hence “(E)UTxO”. Ethereum uses a different model completely. Transactions A transaction has inputs and outputs […]
