On September 22, 2022, the much-anticipated Vasil Hard Fork Upgrade will launch on the Cardano Blockchain. The Hard Fork will improve the scalability of Decentralized Applications while having a substantial influence on the network's transaction costs and mining rewards (Dapp).

The native smart contract language of Cardano is called Plutus. Vasil will provide Plutus version (v)2, the second iteration of Cardano's programming language. As the core component of Cardano, Plutus effectively divides the on-chain transaction validation from the off-chain code that powers smart contracts. This off-chain code runs on a user's computer. The new Plutus v2 abilities will be accessible one epoch following the hard fork on Thursday, which is anticipated to take place on September 27.

Charles Hoskinson, a co-founder of Cardano, remarked during a live stream on September 18 that "we don't anticipate there will be any complications, but there's no going back now." Because the rocket is in the air, no amount of testing or anything else will be able to save us. It will undoubtedly enter orbit unless it explodes in the atmosphere.

New Scripting Will Improve Scalability, Transaction Speed and Space 

Vasil plans to improve a number of Cardano blockchain features. Vasil will allow Cardano applications to become "faster and more sophisticated," making the blockchain easier to build atop and enhancing user experience, according to a blog post by Cardano developer Input Output Hong Kong (IOHK). Additionally, it will reduce transaction fees and enhance the network's capacity for growth.

As a result of Vasil's modifications to the Cardano ledger, inputs and UTXOs can be utilized in scripting contracts without being spent. To put it another way, making it easier to access data stored on the blockchain without the necessity for spending and creating new UTXOs, as was the situation in the past. Whereas previously this led to processing delays, a change in how reference scripts are handled now enables a significant reduction in the size of transactions that run them.

Cardano expands Bitcoin's accounting framework to accommodate smart contracts, also referred to as "extended unspent transaction outputs (EUTXO) and intended to keep as much functionality off the blockchain as possible. This is an important feature for scaling as well as for limiting the potential for assaults and security breaches.

The Security Measures

To connect with decentralised applications under the present Blockchain concept, every wallet user must provide a certain amount of collateral. The collateral requirement was formerly fixed at 15% of the transaction fees. All of the tokens that the Dapp user is transmitting through the Dapp would be lost if the validation failed. However, following the Vasil Hard Fork, they will be sent to a given wallet address if a Dapp transaction fails.
