Smart Contracts and Chaincode¶. They typically are used to automate the execution of an agreement so that all participants can be immediately certain of the outcome, without any intermediary's involvement or time loss. Creating smart contracts entry-level is possible without deep knowledge, but more complex contracts are better to entrust professional developers. The aim of enabling smart contracts is to increase the efficiency and flexibility of the Bitcoin payment function, not to support Dapps. There are many huge advantages of using smart contracts but a smart contract cannot really adapt to ambiguity. Today I spent some time trying to understand how MeowSwap works. This is a question that, these days, has become . These contracts are implemented using the "Ethereum" platforms, which consists of two elements: currency and contracts. Even with not so high ranking on google, Haskell is the first choice of Cardano when it comes to implementing a programming language. Smart contracts not only specify the rules and penalties relating to an arrangement in the same way as a conventional contract but also implement those obligations automatically. This means they have a balance and they can send transactions over the network. What makes these legal agreements innovative is that their execution is made automatic through the use of computers. Smart contracts digitize agreements by turning the terms of an agreement into computer code that automatically executes when the contract terms are met. .

A smart contract is a computer program that automatically executes actions according to the terms of the contract without intermediaries. The digital agreements can communicate with each other and influence the execution of one another. the terms of the agreement are then distributed over a decentralized blockchain network. Remember that the blockchain does not forgive you any errors because of its immutability! Therefore, it might be impractical to deploy the same scale of smart contracts on Bitcoin as on Ethereum and is also dangerous for the bitcoin network in terms of network security and speed. They are declared outside of the functions in the smart contract and have initial values. In technical terms, it is an automated or self-executing contract that holds the agreement between two parties embedded using code. Why the concurrency issue is a big problem the even more problematic thing is that they are not using smart contracts!That means you are sending your ADA to the wallet of the MeowSwap devs. It is believed that this feature of smart contracts is marketed as the solution to traditional contracts, which can be easily breached.
