Advantages of implementing MAST
MAST will bring multiple benefits to the Bitcoin blockchain. Firstly, by reducing the size of the transactions with the use of the Merkle tree, they take up less space within the blockchain. With which you can improve the scalability problem that the network presents, since it does not have to include all the information within the chain. This leaves more free space to process more transactions quickly.
Also, the level of Privacy of transactions will also be improved on the blockchain. With the implementation of AST in MAST, only the essential information of a transaction or script can be revealed. Without having to show all the previously established conditionals and restrictions. Thus, conditionals and restrictions that are not activated in the transaction will simply not be included within the blockchain. Guaranteeing the privacy of users by not disclosing their data, and optimizing the space and use of the blockchain.
On the other hand, MAST can also contribute to improving the fungibility of the system, since it could prevent certain cryptocurrencies from being associated with a smart contract or a particular transaction.
However, these functionalities are still under development and testing, so it will take some time for us to finally see them applied in the Bitcoin blockchain.
