Cardano uses the extended UTxO accounting model.

EUTxO differs from Ethereum’s account-based model. In Ethereum’s model, everyone has an account with a balance. When funds are transferred from one account to another, then balances are updated.

#Cardano $ADA
The ‘E’ in EUTxO stands for extended, improving on Bitcoin’s UTxO. Whereas UTxO smart contracts only interact with immediate requests to confirm a transaction, #Cardano’s EUTxO model improves on this.

Learn more about EUTxO here: essentialcardano.io/faq/what-is-an…
💡To better understand EUTxO, read about how it supports multiassets and smart contracts⬇️
iohk.io/en/blog/posts/…
EUTxO is a transaction mechanism combining:

➡️ Smart contracts: these lock-up UTxOs, $ADA, native assets & #NFTs.
➡️ Redeemers: user-supplied data provided to unlock locked assets & spend them.
➡️ Datum: data such as a high score, user information or other information relevant to your app
➡️ Context: information like metadata about the transaction being validated
#Plutus Core scripts can be checked to enable the confirmation of whether a tx will validate in your wallet before it goes on-chain.

Essentially protecting you from having to pay tx fees if your transaction fails.
This thread is part of a series on understanding #Plutus and the upcoming June HF improvements.

We’re delighted to announce that the new #EssentialCardano site is now available for the #CardanoCommunity to try in 𝐨𝐩𝐞𝐧 𝐛𝐞𝐭𝐚!

We previewed the platform in March’s edition of #Cardano360 and now, it’s open to all!

What is Essential Cardano?

A community-driven, rich directory of sharable content to showcase #Cardano & the incredible ecosystem building on it.

Also, it is:

👉 An open-source content hub
👉 Currently in beta
👉 Easy to share answers to Cardano questions

🧵 1/n
Where did Essential Cardano come from?

🌱 An evolution of the Essential Cardano GitHub repo, an open, community-sourced content index of #Cardano related projects

🎓 Created in response to the community’s request for a Cardano ‘wiki’, an accessible source of truth.

CIPs coming with June’s HF:

CIPs (Cardano Improvement Proposals) present new features to the #Cardano network that are key to bettering our blockchain

The upcoming HF introduces:
CIP-31: Reference Inputs
CIP-32: Inline Datums
CIP-33: Reference Scripts
CIP-40: Collateral Outputs Image
Reference inputs allow you to read datums from outputs without consuming and recreating them.

➡️Multiple #DApps will therefore be able to read from the same datum at the same time, improving concurrency. Image
Inline datums allow you to store the data on-chain as opposed to just storing a hash of it on-chain as #Cardano currently does.

➡️This provides a more convenient architecture where devs don’t have to include the data when interacting with the script. Image

#Cardano & its smart contract platform, #Plutus, are set to undergo significant enhancements in June’s HF.

This series of threads on @JohnAlanWoods’s Plutus explainer will help you understand:

Plutus Core
EUTXO
CIPs & improvements
Determinism, parallelism & concurrency

🧵⤵️
🤓Let’s start with what is Plutus Core:

Plutus Core is Cardano’s native smart contract language that is deterministic, verified, functional, and compact.

Providing a safe programming environment to create scripts with Haskell.
👉 Plutus Core scripts enable the creation of #DApps & multiasset support on the blockchain (ie anyone can create their own tokens)
