Non-production blockchain networks used for development and testing. Tokens on these networks have no monetary value and can be obtained via faucets (airdrops). Solana operates devnet (development, frequently reset) and testnet (stress testing, closer to mainnet specs). Ethereum has Sepolia and Holesky testnets. Always test on devnet before deploying to mainnet.

A set of validators working together to maintain a single Solana ledger. Solana operates three main clusters: mainnet-beta (production), devnet (development), and testnet (stress testing). Each cluster has its own genesis block, token supply, and independent validator set. Validators in a cluster discover each other via the gossip protocol.
The practice of developing and testing Solana programs against a local validator (solana-test-validator) or in-process test harness (Bankrun, LiteSVM). Local development allows instant transaction confirmation, free airdrops, account cloning from mainnet, and rapid debugging. Programs are deployed locally before moving to devnet for integration testing.
A service that distributes free tokens on test networks (devnet/testnet) for development and testing. Solana's CLI includes `solana airdrop` which requests SOL from the devnet faucet (up to 2 SOL per request with rate limits). Web-based faucets also exist. Faucet tokens have no real value—they exist solely for testing purposes.

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.
