EVM: The Ethereum Virtual Machine is a runtime environment for smart contracts on the Ethereum blockchain, providing a secure and deterministic way to execute code.

PoS: Proof-of-Stake is a consensus mechanism used in blockchain networks, where validators are chosen to validate transactions based on the amount of cryptocurrency they hold and stake as collateral.

PoW: Proof-of-Work is a consensus mechanism used in blockchain networks, where validators are chosen based on their computational power to solve complex mathematical problems and validate transactions.

L1: Layer 1 refers to the underlying blockchain protocol layer that handles basic transaction processing and consensus. Examples of L1 blockchains include Bitcoin and Ethereum.

Nodes: Nodes are computers or devices that run the blockchain software and participate in transaction validation and consensus on the network.

Metamask: MetaMask is a browser extension that allows users to interact with Ethereum blockchain applications directly from their browser.

zkProofs: Zero-knowledge proofs are cryptographic protocols that enable one party to prove knowledge of certain information to another party without revealing any information beyond the proof itself.

Validators: Validators are nodes that participate in consensus mechanisms, such as Proof-of-Stake, to validate transactions on a blockchain network and earn rewards for doing so.

Solidity: Solidity is a programming language used to write smart contracts on the Ethereum blockchain.

APIs: APIs (Application Programming Interfaces) are software interfaces that allow applications to interact with each other, often used to retrieve data from a service or platform.

Epoch: In blockchain networks, an epoch refers to a set number of blocks that are validated by the network before the consensus mechanism selects new validators or makes other changes to the network's configuration.
