Abstract
Systems, methods, and apparatus are provided for dynamic DAG-based blockchain authentication protocols. An authentication engine may deploy two associated parent nodes in a private blockchain network. The first parent node may include first party data and the second parent node may include smart contract logic including an aggregation threshold. The authentication engine may receive transaction data for a plurality of transactions between the first party and a second party and validate the transactions against the aggregation threshold. If a transaction exceeds the aggregation threshold, the authentication engine may aggregate a threshold number of transaction nodes into an aggregated node cryptographically linked to the second parent node and generate a new transaction node including a self-executing smart contract cryptographically linked to the aggregated node. At settlement, the authentication engine may validate links between the aggregated nodes and the second parent node and retrieve associated first party data.
