The particular information to be transmitted must be specified by the users.What is Stellar?Stellar is a specialized platform for digital-currency applications, similar to Corda. Stellar is a simpler and more accessible cryptocurrency than Ethereum. Stellar, on the other hand, may support a wide range of languages, including Python, JavaScript, Golang and PHP. But does Stellar have a smart contract?Yes, Stellar supports smart contracts, but Stellar contracts are not Turing complete so how is a Stellar smart contract created? A Stellar smart contract is a collection of connected and executed transactions using various constraints and is designed to send, store and trade value.Multisignature — a notion that requires the signatures of multiple parties to sign transactions originating from an account — and Batching / Atomicity — the concept of combining many operations in one transaction — are two examples of restrictions for Stellar smart contracts. Atomicity is the promise that if one operation in a series fails, the rest of the transaction will still work.Stellar, like Fabric, executes program codes on top of Docker containers, resulting in lower overhead. The execution cost of a single transaction at Stellar, for example, is only $0.0000002, which is almost insignificant. Furthermore, one transaction in Stellar takes roughly 5 seconds on average to complete, compared to 3.5 minutes in Ethereum. Stellar is thus an excellent platform for digital money applications. Stellar, like Ethereum, uses the account-based approach as its data model. Stellar Consensus Protocol (SCP) is the company's consensus algorithm. SCP allows parties to agree without relying on a closed system to keep track of financial transactions. Because Stellar is permissioned, reaching a consensus is simple.What is Rootstock or RSK?RSK works on top of Bitcoin and allows for faster transaction processing. RSK, for example, may confirm a transaction in less than 20 seconds. Meanwhile, RSK is Ethereum-compatible (e.g., adopting Solidity to implement contracts). Rootstock smart contracts are Turing complete as well. RSK also created its virtual computers for running smart contracts. RSK's data model is also account-based, even though RSK is a public blockchain system.RSK created a consensus mechanism based on PoW and implemented it in a lightweight manner, lowering the overhead. RSK, like Corda and Stellar, was designed to enable primarily digital-currency applications. RSK has validity in that it is significantly safer than systems that are not based on blockchains because it is built on top of Bitcoin. However, it may place additional strain on the Bitcoin blockchain. RSK needs to figure out how to remedy this situation.Smart contract platforms comparedThe main aspects of the above-mentioned smart contract platforms are explained in this section.Execution environmentEVM is used to execute Ethereum contracts. JVM and RSK virtual machines are used by Corda and Rootstock, respectively. On
