Exfer is a permissionless proof-of-work blockchain for autonomous machine-to-machine commerce. It combines Argon2id memory-hard mining, an extended UTXO model, and Exfer Script — a total functional combinator language — for transaction conditions. Use when an agent needs to send payments, check balances, create hash-time-locked contracts (HTLCs), mine blocks, or interact with blockchain-based machine commerce.
