Ganache creates a local Ethereum blockchain for development and testing. It allows developers to deploy contracts and simulate transactions without real ETH.

Web3.js is a JavaScript library for interacting with Ethereum, enabling dApps to communicate with nodes. It handles tasks like sending transactions and reading blockchain data.

A token standard, like ERC-20, defines rules for creating tokens on a blockchain. It ensures compatibility for cross-chain transfers and DeFi applications.

Interoperability protocols allow different blockchains to communicate and share data or assets seamlessly. Examples include Polkadot and Cosmos, which facilitate cross-chain transactions.

Rust’s async programming, with crates like Tokio, enables high-throughput transaction processing in blockchain nodes. It supports concurrent handling of network requests and validations.

Rust’s zero-cost abstractions allow developers to write high-level code without runtime performance penalties, ideal for blockchain runtimes. This ensures efficient execution of smart contracts and consensus algorithms.

The #[account] macro in Anchor is used to define and validate account structures for Solana smart contracts. It simplifies account management and ensures data integrity.

Rust’s ownership model enforces strict rules on data access, preventing issues like double-spending in blockchain applications. It ensures compile-time safety for complex data structures.

Anchor is a Rust-based framework designed for developing secure and efficient smart contracts on Solana. It simplifies the process with macros and abstractions for Solana’s programming model.

Whitelists let selected users mint first. It rewards loyal fans and avoids gas spikes.

They link physical goods to NFTs. This proves ownership and authenticity.

Many people co-own one NFT. This makes pricey NFTs affordable.

Decentraland is a virtual world where users buy land and items as NFTs. It blends gaming and digital ownership.

Royalties ensure creators earn money each time their NFT is resold. This gives artists ongoing income.

Centralized oracles can be a single point of failure. If they provide false data, contracts relying on them can be exploited.
