Cardano’s Extended UTXO accounting model – built to support multi-assets and smart contracts
Cardano uses an innovative Extended UTXO accounting model to support multi-assets and smart contracts. In the first of a two-part blog, we look at the different blockchain accounting systems and why EUTXO matters

Blockchain networks are complex data structures. Transactions continuously crisscross the chain, creating digital footprints that require careful tracking and management to maintain the integrity and reliability of the underlying ledger.
Two major accounting ledgers exist in the blockchain space: UTXO-based blockchains (Bitcoin, for instance), and Account/Balance chains…
Not long till 'd' (=0) day
We are fast approaching full decentralization of block production on Cardano. It's a good time to reflect on the network’s evolution

At the end of March, we’ll reach another milestone for Cardano when we’ll see d, the parameter that governs what percentage of transactions are processed by the genesis nodes, get to zero. At this point, responsibility for block generation will be fully decentralized. In other words, Cardano’s network of 1,800+ community pools will be solely responsible for producing blocks.
D=0 day will be a landmark moment in Cardano's continuing journey. When we deployed the Shelley update back in July 2020, d was set to an initial 1.0, meaning that every block was produced by IOHK’s network of federated nodes. Of course, this was the antithesis of…
