Block Explorer
Plain English
A website that lets you look up any transaction, wallet, or block on the blockchain - like Google for blockchain data. For Solana, popular explorers are Solscan and Solana Explorer. You can paste a transaction ID or wallet address to see all details.
Technical
Web-based tools providing searchable interface for blockchain data: transactions, blocks, addresses, smart contracts, token transfers, and network statistics. Explorers parse raw blockchain data into human-readable format. Solana explorers (Solscan, SolanaFM, Solana Explorer) display transaction signatures, compute units, account changes, and program invocations.
