Account Abstraction Layer (AAL)

The Account Abstraction Layer (AAL) is the technological framework that enables the construction of smart contracts on the Qtum blockchain. Qtum’s basic layer adheres to the UTXO concept utilized by blockchains such as Bitcoin. The AAL on Qtum enables the Ethereum accounts concept to be “abstracted” or transferred in order to function on top of the UTXO architecture. Qtum’s AAL acts as a computer intermediary, allowing the UTXO and accounts models to communicate.
