Method for trading a digital asset

A computer implemented method, the method including the steps of:

• (i) at a key generator subsystem:
• generating a public-private encryption key pair for a device, and transmitting the generated public key to be registered on a blockchain;
• (ii) at one or more processors:
• encrypting a digital asset via the public key of the device, and linking or associating the encrypted digital asset to a non-fungible token (NFT), in which the NFT is associated with a smart contract written on the blockchain;
• and
• (iii) at the device:
• requesting access to the NFT-linked digital asset;
• receiving the NFT-linked digital asset when the requirements of the smart contract are met;
• and decrypting the NFT-linked digital asset using the private key,
• wherein the public-private encryption key pair is automatically generated at the first boot or start-up of the device.

A system comprising:

• (i) a key generator subsystem, that is configured to generate a public-private encryption key pair for a device, and transmit the public key to be registered on a blockchain;
• (ii) one or more processors configured to encrypt a digital asset via the public key of the device, and link or associate the encrypted digital asset to a non-fungible token (NFT), in which the NFT is associated with a smart contract written on the blockchain;
• and
• (iii) the device, in which the device is further configured to:
• request access to the NFT-linked digital asset;
• receive the NFT-linked digital asset when the requirements of the smart contract are met;
• and decrypt the NFT-linked digital asset using its private key,
• in which the public-private encryption key pair is automatically generated at the first boot or start-up of the device.

A computer implemented method, the method including the steps of:

• (i) at a key generator subsystem:
• generating a public-private encryption key pair for a device, and transmitting the generated public key to be registered on a blockchain;
• (ii) at one or more processors:
• generating a symmetric key, encrypting a digital asset via the symmetric key, generating a hybrid key by encrypting the symmetric key using the public key of the device, and linking or associating the encrypted digital asset to a non-fungible token (NFT), in which the NFT is associated with a smart contract written on the blockchain;
• and
• (iii) at the device:
• requesting access to the NFT-linked digital asset;
• receiving the NFT-linked digital asset and the hybrid key when the requirements of the smart contract are met;
• and decrypting the hybrid key using the private key and decrypting the NFT-linked digital asset using the symmetric key.
• in which the public-private encryption key pair is automatically generated at the first boot or start-up of the device.
