Abstract
An example operation may include one or more of connecting, by a smart note, to a blockchain configured to store an asset of a user on a ledger, acquiring, by a smart note, a value of the asset from the ledger, displaying, by a smart note, the value on a display screen located on the smart note in response to a detection of a smart note button press event, generating, by a smart note, an asset address key pair, checking, by a smart note, a status of a private key associated with the smart note, and displaying, by a smart note, a trusted symbol next to the value on the display screen, if the status of the private key indicates that the private key has never been used.
Claims10
A computer device, comprising:
- a display screen;
- a button;
- a memory configured to store one or more instructions;
- and
- a processor that when executing the one or more instructions causes the processor to perform operations comprising:
- connecting to a blockchain ledger storing assets of a user;
- acquiring a value of the asset from the blockchain ledge;
- detecting a press of the button;
- and
- displaying the value of the asset in response to detecting the press of the button;
- and
- generating a new asset address key pair in response to detecting the press of the button:
- displaying a trusted symbol indicating that the generated new asset address key pair has not been used;
- receiving a request for a transaction from the user to transfer a partial value of the asset to the blockchain ledger;
- signing the transaction with a private key of the new asset address key pair, wherein the transaction comprises a transfer of the partial value of the asset to the blockchain ledger;
- submitting the blockchain transaction to the blockchain ledger, wherein the blockchain transaction comprises the transfer of the partial value of the asset to a client of the blockchain ledge;
- receiving confirmation that the transaction has been confirmed for inclusion in the blockchain ledger from a smart contract installed on the blockchain ledger;
- in response to receiving the confirmation, generating a new key pair and transferring the remaining value of the asset to the new key pair before displaying the remining value of the asset.

- receiving a request for a transaction from the user to transfer a partial value of the asset to the blockchain ledger;
- signing the transaction with a private key of the new asset address key pair, wherein the transaction comprises a transfer of the partial value of the asset to the blockchain ledger;
- submitting the blockchain transaction to the blockchain ledger, wherein the blockchain transaction comprises the partial value of the asset to a client of the blockchain ledger;
- receiving confirmation that the transaction has been confirmed for inclusion in the blockchain ledger from a smart contract installed on the blockchain ledger;
- in response to receiving the confirmation, generating a new key pair and transferring the remaining value of the asset to the new key pair before displaying the remining value of the asset.
9 more elements
A non-transitory computer readable medium comprising one or more instructions that when executed by a processor of a computer device cause the processor to perform:
- connecting to a blockchain ledger storing assets of a user;
- acquiring a value of the asset from the blockchain ledger;
- detecting a press of a button;
- and
- displaying the value of the asset in response to detecting the press of the button;
- generating a new asset address key pair in response to detecting the press of the button;
- displaying a trusted symbol indicating that the generated new asset address key pair has not been used;
- receiving a request for a transaction from the user to transfer a partial value of the asset to the blockchain ledger;
- signing the transaction with a private key of the new asset address key pair, wherein the transaction comprises a transfer of the partial value of the asset to the blockchain ledger;
- submitting the blockchain transaction to the blockchain ledger, wherein the blockchain transaction comprises the partial value of the asset to a client of the blockchain ledger;
- receiving confirmation that the blockchain transaction has been confirmed for inclusion in the blockchain ledger from a smart contract installed on the blockchain ledger;
- in response to receiving the confirmation, generating a new key pair and transferring the remaining value of the asset to the new key pair before displaying the remining value of the asset.
