Ethereum is a decentralized open-source blockchain with smart contracts functionality. Its native currency Ether (ETH), is the second-largest cryptocurrency and number one altcoin by market capitalization. The Ethereum network is tailored for building crypto solutions like decentralized finance (DeFi), GameFi, non-fungible tokens (NFTs), decentralized autonomous organizations (DAOs), etc.

Ethereum is a public decentralized blockchain technology, where developers can build and deploy applications that function without the need for a central authority. To make this easier, the network leverages the Solidity programming language and Ethereum virtual machine which helps developers create and launch applications with smart contract functionality.

Smart contracts are publicly verifiable codes that automates agreements between two or more parties. Basically, these codes self-execute encoded actions when predetermined conditions are met.

Staking is a process of earning yield on your idle crypto assets by locking them in a crypto protocol for a specified duration as a means of contributing to its security. Ethereum transitioned from a Proof-of-Work (PoW) to a Proof-of-Stake (PoS) consensus mechanism on September 15, 2022, in an event christened “The Merge.” The Merge was a key part of Ethereum’s roadmap to achieve high-level scalability, decentralization and security while remaining sustainable. Unlike PoW, which requires the use of expensive hardware, PoS reduces the barrier of entry for validators by leveraging the use of crypto tokens as the core foundation of its consensus process.

Gas is the unit for measuring transaction fees that users pay for conducting transactions on Ethereum. During periods of network congestion, gas can be extremely high, causing validators to prioritize transactions based on their fees.
