The production blockchain network where real-value transactions occur. Solana's production network is 'mainnet-beta'. Deploying to mainnet requires thorough testing on devnet/testnet, security audits for significant programs, and careful consideration of upgrade authority management. Mainnet state is permanent and transactions involve real financial value.

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.
Use this compact block when you want to give an agent or assistant grounded context without dumping the entire page.
Mainnet (mainnet) Category: Blockchain General Definition: The production blockchain network where real-value transactions occur. Solana's production network is 'mainnet-beta'. Deploying to mainnet requires thorough testing on devnet/testnet, security audits for significant programs, and careful consideration of upgrade authority management. Mainnet state is permanent and transactions involve real financial value. Related: Testnet / Devnet, Cluster
Use glossary context, relationships, mental models, and builder paths to get structured answers instead of generic chat output.
Optional: paste Anchor, Solana, or Rust code so the Copilot can map primitives back to glossary terms.
The Copilot will answer using the current term, related concepts, mental models, and the surrounding glossary graph.
These branches show which concepts this term touches directly and what sits one layer beyond them.
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.
These are the next concepts worth opening if you want this term to make more sense inside a real Solana workflow.
These entries are easy to mix up when you are reading quickly, prompting an LLM, or onboarding into a new layer of Solana.
The memory pool maintained by each blockchain node containing unconfirmed transactions that have been validated but not yet included in a block. Miners/validators select transactions from the mempool typically prioritizing those with the highest fee rate. Each node's mempool is independent and may differ based on propagation delays; during high-demand periods, the mempool can grow significantly, causing fee spikes as users compete for limited block space.

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.
