A receipt paradigm is a receipt-focused transaction structure designed for use on the Ethereum consensus layer with shard chains (formerly Ethereum 2.0). The purpose of the paradigm is to improve the utility and usability of decentralized finance (DeFi) applications on the Ethereum network. Ethereum intends to implement a “receipt paradigm” in early 2021, in which each shard chain generates receipts for its respective internal transactions. Receipts will then be stored in the Beacon Chain’s shared memory, where they will be visible to all other shards but not tampered with.
