Solidity is a high-level programming language designed for implementing smart contracts. Smart contracts are self-executing contracts with the terms of the agreement between buyer and seller directly written into lines of code. The code and the agreements contained therein exist across a distributed, decentralized blockchain network. The code controls the execution of the terms of the contract. ..
The useLayoutEffect hook is a React hook that can be used to perform side effects that require immediate DOM layout updates. It is similar to the useEffect hook, but it runs synchronously after all DOM updates have been completed, but before the browser repaints the screen. This makes it ideal for use cases such as measuring DOM elements, or animating or transitioning elements. One of the main b..

pnpm is a fast and disk space efficient package manager for JavaScript. It uses a content-addressable filesystem to store all files from all module directories on a disk. This means that pnpm only stores one copy of each file, regardless of how many packages depend on it. This can save a lot of disk space, especially for large projects with many dependencies. pnpm is also very fast. It can insta..
The reason why Gossip Protocol (TCP) is used is that when a transaction occurs, it must be able to push even if there is no request. When a transaction occurs in one node, the information must be spread to other nodes as quickly and widely as possible. At this time, whether each transaction is correct is determined by the basic rules and consensus algorithm of the Bitcoin network. Join a network..
gRPC and HTTP API are two different technologies used for building and interacting with APIs (Application Programming Interfaces). They have distinct characteristics and use cases: gRPC: Definition: gRPC stands for "Google Remote Procedure Call." It is an open-source RPC (Remote Procedure Call) framework developed by Google. Communication Protocol: gRPC uses HTTP/2 as its underlying communicatio..
