Geth is an Ethereum node implementation built using the Go programming language. It is available in the three interfaces, including JSON-RPC server, command-line, and an interactive console. Geth can be leveraged for Blockchain development.
It is the official Ethereum wallet developed by the creators of Ethereum. When it comes to Ethereum, before you can start using the platform, you must have a designated place where you can store your Ether tokens and execute your smart contracts.
It is a compiler used for small contracts. It supports deploying, testing, and debugging smart contracts. Its code analyzer helps developers write the best codes and connects to the blockchain using Metamask.
Post compilation, a development environment needs to be set to deploy contracts on the Ethereum blockchain. An Ethereum client is needed for this and that is where Parity comes into the picture.
Security plays a vital role in the development of each tool. The solidity code must be secure and tamper-resistant. It helps format solidity codes and also helps fix security issues, if any, in the code.
