Abstract
Embodiments relate to providing trusted tokenized transactions in a blockchain system. In one embodiment, a tokenization request may include identification information. A fiduciary server may apply a cryptographic private key to a hash of the identification information to generate a digital signature. An exchange server may cause a transmission of the digital signature to a blockchain. The blockchain includes a set of code instructions that verify the digital signature. The verification may include applying the public key corresponding to the cryptographic private key to decrypt the digital signature to re-generate the hash of the identification information. The hash may ensure the integrity of the identification information. The code instructions recorded on the blockchain, when executed, cause a computer to generate a blockchain unit. The tokenized transactions are traceable to the digital signature of the fiduciary server. This may provide a trusted transaction for users of the blockchain regarding the tokenized transactions.
