Plain meaning

Start with the shortest useful explanation before going deeper.

A proof-of-work mining token on Solana where miners compete to find valid hashes using a smart contract that implements Bitcoin-style mining mechanics on a proof-of-stake chain. Ore mining involves submitting hash solutions to an on-chain program, with difficulty adjusting based on participation. The project attracted significant attention and briefly caused Solana network congestion due to high mining transaction volume.

Mental model

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.

Technical context

Place the term inside its Solana layer so the definition is easier to reason about.

Teams, protocols, tools, and the wider Solana product landscape.

Why builders care

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.

Concept graph

See the term as part of a network, not a dead-end definition.

These branches show which concepts this term touches directly and what sits one layer beyond them.

Branch

SOL

The native token of the Solana blockchain, used for paying transaction fees, staking, and rent. 1 SOL equals 1 billion lamports. SOL has an inflationary supply schedule starting at 8% annually, decreasing by 15% per year, with a long-term floor of 1.5%. Transaction base fees (5,000 lamports) are partially burned.

Branch

Solana Virtual Machine (SVM)

The Solana Virtual Machine—the execution environment that runs on-chain programs. SVM loads SBF bytecode, provides syscalls for account access and cryptographic operations, enforces compute budgets, and manages memory. The SVM is being modularized (via the SVM API) to enable use in rollups and other environments outside the main Solana validator.

dApp (Decentralized Application)

An application with its backend logic running on a blockchain as smart contracts rather than centralized servers. dApps typically have a traditional web frontend that interacts with on-chain programs via RPC. Users authenticate with wallets instead of username/password. Examples: Uniswap (Ethereum DEX), Jupiter (Solana DEX), Magic Eden (NFT marketplace).

Parcl

A Solana-native DeFi protocol providing exposure to real estate price indices through perpetual-style markets. Parcl tracks price-per-square-foot in major US cities, allowing users to take long or short positions on residential real estate price movements without owning physical property. The protocol brings real estate market speculation on-chain with Solana's low fees and fast settlement.
