A decentralized social media protocol where core identity (Farcaster IDs) is registered on-chain via smart contracts on Optimism, while social content is stored on a distributed network of hubs. Farcaster supports composable Frames for embedded applications within posts. The protocol raised $150 million at a $1B+ valuation in May 2024.

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.
Wallets, signing flows, dApps, and key management concepts.
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.

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.
The intersection of social media and decentralized finance, where social interactions, content creation, and community engagement are tokenized and governed by blockchain protocols. SocialFi platforms give users ownership of their social graph, content, and reputation as portable digital assets. Led by Farcaster (social graph on Optimism) and Lens Protocol (social data as NFTs on zkSync).
A W3C standard for self-sovereign digital identifiers created, owned, and controlled by the individual rather than a centralized authority. DIDs use public-key cryptography for verification without traditional identity providers. In blockchain contexts, DIDs map to on-chain addresses and enable verifiable authentication across protocols.
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.
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.
Buying an asset with the intent to sell it quickly at a higher price rather than holding long-term. Common in NFT launches where flippers mint at launch price and immediately list above mint price, and in token trading where the goal is to buy at launch and sell during the initial pump. Flipping requires speed and market timing rather than fundamental analysis.

These entries live beside the current term and help the page feel like part of a larger knowledge graph instead of a dead end.
The vision of a decentralized internet built on blockchain technology, where users own their data, identity, and digital assets. Web1 was read-only (static pages), Web2 is read-write (platforms like social media), Web3 is read-write-own (permissionless, user-sovereign). Web3 applications use wallets instead of logins and smart contracts instead of centralized servers.
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).
Software or hardware that manages cryptographic keys and enables users to sign transactions, view balances, and interact with dApps. Hot wallets (Phantom, Solflare, Backpack) are internet-connected for convenience. Cold wallets (Ledger, Trezor) store keys offline for security. Wallets don't actually 'hold' tokens—they hold the private keys that control on-chain accounts.
A 12 or 24-word human-readable backup of a wallet's master private key, generated using BIP-39 standard. The seed phrase can deterministically regenerate all derived keypairs (BIP-44 derivation paths). Losing the seed phrase means permanently losing access to all associated accounts. Never share, photograph, or store seed phrases digitally in plain text.
