Abstract
An enhanced federated custodian system is described. One embodiment is directed to a computer system executing instructions to: receive, from one or more members of a federated blockchain on a network of computing devices, an approval for a transaction associated with an authentication capsule; generate, via a first trusted execution environment, a first machine readable code in response to receiving the approval for the transaction; transmit to a cold interaction system, the first machine readable code; and the cold interaction system comprising one or more processors and one or more memories, the one or more memories comprising instructions executable by the one or more processors to: receive the first machine readable code comprising the encrypted information and the approval; decrypt the encrypted information for the transaction and the approval; and generate a private key that corresponds to a public key for the transaction.
