Account Abstraction Layer (AAL)

    The Account Abstraction Layer (AAL) is the technical infrastructure that enables the development of smart contracts on the Qtum blockchain. Qtum’s foundational layer adheres to the UTXO model used by blockchains such as Bitcoin. The AAL on Qtum enables the Ethereum account model to be “abstracted” or transferred in order to work on top of the UTXO model. Qtum’s AAL acts as a computing intermediary, allowing the UTXO and account models to interact.
