The #Qtum Account Abstraction Layer (#AAL) represents an innovative solution that merges the UTXO and Accounts models, delivering significant advantages to both users and developers.🌐🔒

#Qtum #BlockchainInteroperability

You may already be familiar with the dilemma faced by #Qtum in choosing between #Bitcoin's UTXO model and #Ethereum's Account Model. The UTXO model treats coins separately, making selecting which ones to utilize difficultly. On the other hand, the accounts model lacks security.

This is where #Qtum's #AAL comes in! It revolutionizes the UTXO model by introducing new opcodes like OP_CREATE, OP_CALL, and OP_SPEND, making contracts, internal transactions, and gas refunds possible while ensuring security and efficiency.

#Qtum's AAL is the key to managing the #UTXO set efficiently. Spendable opcodes keep the network running smoothly, and terminated contracts are removed, maintaining network efficiency.
