Capacity Credits are a key component in paying for usage of the Lit network, specifically for operations that occur on the network itself. They allow you to reserve a specific amount of capacity (i.e. requests per second) on the network over a pre-defined period (e.g. one week).| developer.litprotocol.com
Programmable Key Pairs (PKPs) are ECDSA public/private key pairs created by the Lit network using Distributed Key Generation (DKG). Each Lit node holds a share of the private key, and more than two-thirds of these shares must be collected to execute a given action (i.e. signing a transaction).| developer.litprotocol.com
Lit Actions are immutable JavaScript programs that run on a decentralized Lit network. They enable powerful, blockchain-agnostic applications with built-in cryptographic capabilities like signing and encryption.| developer.litprotocol.com
