# Enhanced Security

In SRC-101, asset loss by mistakenly spenting UTXO is not an issue any more.

SRC-101 decouples Name Assets from a strict binding with UTXOs, preventing asset loss due to normal UTXO spending or phishing attacks from UTXO transfers. In SRC-101, when asset was minted, it will be binded with sender address of that mint transaction.

Thus, wherever UTXO goes later, it will not have any impact on the balance of SRC-101 tokens. All user operation of bit name servce need verification from last owner's signature. SRC-101 also makes the deploy transaction UTXO hash as an unique identity, so it's much more determinate and easier to be tracked.
