This document discusses blockchain and APIs. It provides information about an upcoming series of API conference events in various global locations. It then discusses how blockchain networks like Solana function as globally accessible computers through mechanisms like proof-of-work, validators, and transactions. It notes Solana has attributes like planet-size state, natural transactionality, and permissionless composability. It outlines Solana's architecture including clients, RPC nodes, validators, programs, and accounts. It also discusses Solana's JSON RPC API and how instructions allow programs to interact on the blockchain. It highlights a Solana client project called Better Call Sol.
