The financial model governing validator profitability including staking rewards (inflation), transaction fee revenue, MEV tips, and operational costs (hardware, bandwidth, data center). On Solana, validators earn ~6-7% APY from inflation plus priority fees and Jito MEV tips, offset by costs of running high-spec hardware.

Use the quick analogy first so the term is easier to reason about when you meet it in code, docs, or prompts.
Think of it as a building block that connects one definition to the larger Solana system around it.
Place the term inside its Solana layer so the definition is easier to reason about.
Shared crypto concepts that frame the broader ecosystem.
Turn the term from vocabulary into something operational for product and engineering work.
This term unlocks adjacent concepts quickly, so it works best when you treat it as a junction instead of an isolated definition.

A node that participates in the Solana network by validating transactions, voting on blocks, and (when selected as leader) producing new blocks. Validators run the Agave, Firedancer, or Jito client software, require significant hardware (128+ GB RAM, high-core CPU, NVMe SSD), and earn rewards from inflation and transaction fees.
SOL earned by validators and their delegators each epoch as compensation for participating in consensus and securing the network, funded by protocol inflation rather than solely transaction fees. Rewards are proportional to a validator's active stake and are credited at the end of each epoch to stake accounts automatically; the effective APY depends on the current inflation rate, the percentage of total SOL staked, and the validator's commission rate. Validators set a commission (0–100%) representing the fraction of rewards they keep before passing the remainder to delegators.
Solana's protocol-level mechanism for issuing new SOL to reward validators and stakers, starting at an initial annual inflation rate of 8% at genesis (Q1 2021) and decreasing by 15% of the current rate each year until reaching a long-term fixed rate of 1.5% per year. New SOL is minted each epoch proportionally to each validator's active stake and distributed as staking rewards; 50% of transaction base fees are burned, creating partial deflationary pressure. The net effective inflation rate depends on the proportion of SOL actively staked.
These are the next concepts worth opening if you want this term to make more sense inside a real Solana workflow.

These entries live beside the current term and help the page feel like part of a larger knowledge graph instead of a dead end.
A distributed, append-only ledger that records transactions in cryptographically linked blocks. Each block contains a hash of the previous block, forming an immutable chain. Nodes in the network maintain copies of the ledger and reach agreement through consensus mechanisms. Blockchains enable trustless, decentralized record-keeping without a central authority.
The protocol by which nodes in a distributed network agree on the current state of the ledger. Common mechanisms include Proof of Work (Bitcoin), Proof of Stake (Ethereum, Solana), and BFT variants. Consensus ensures all honest nodes converge on the same transaction history despite potential network delays or malicious actors.
A consensus mechanism where validators are selected to produce blocks based on the amount of cryptocurrency they have staked (locked) as collateral. PoS is energy-efficient compared to Proof of Work. Misbehaving validators risk losing their stake (slashing). Solana, Ethereum (post-Merge), Cosmos, and Cardano use PoS variants.
A consensus mechanism where miners compete to solve computationally expensive puzzles to produce blocks and earn rewards. PoW provides strong security (51% attack resistance) but is energy-intensive. Bitcoin and pre-Merge Ethereum use PoW. The difficulty adjusts to maintain target block times regardless of total network hash power.
