That means code that compiles with version 0.x.y can be expected to compile with 0.x.z where z > y. A smart contract is a program written/stored on the Blockchain. In a similar to way to ERCs and as we work towards to more interoperable smart contracts, being able to quickly examine those interfaces that you want to integrate is a time saver. You can look at the file ./node_modules/solc/package.json and see something like "solc@^x.y.z" where x.y.z is the version number that is being used. If solc is called with the option --standard-json, it will expect a JSON input (as explained below) on the standard input, and return a JSON output on the standard output. Ethereum Stack Exchange is a question and answer site for users of Ethereum, the decentralized application platform and smart contract enabled blockchain. With Solidity, you can create contracts for uses such as voting, crowdfunding, blind auctions, and multi-signature wallets. If you are using solc / Solidity (command line interface) you can use the command web3.eth.compile which will then spit out something like: This will compile your code and give you information like compiler version, etc. Comments are of course not permitted and used here only for explanatory purposes.
