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.

Federated custodian

A method is disclosed. The method includes determining, by a delegated certificate authority computer, a tier from a plurality of tiers for a digital wallet provider based on a list of qualifying criteria. The method also includes generating a digital certificate based on the tier, where the digital certificate is used by a digital wallet application computer associated with the digital wallet provider to complete interactions using a digital currency maintained by a blockchain network. The method further includes transmitting, by the delegated certificate authority computer to a digital wallet application computer, the digital certificate.

Delegated certificate authority system and method

A method is disclosed. The method comprises receiving, by a processing network computer, a plurality of clearing files from a plurality of transport computers. The processing network computer may then generate, based on the data in the plurality of clearing files, a settlement file comprising a first settlement amount and a first destination associated with an account at a custodian computer. The processing network computer may then transmit the settlement file to an authorizing entity computer. The processing network computer may then transmit a transfer instruction file comprising the first destination, a second settlement amount, and a second destination associated with a transport computer to a custodian computer. Later, the authorizing entity computer sends the first settlement amount to the first destination at the custodian computer. Then the custodian computer, or the processing network computer, sends the second settlement amount to the second destination associated with the transport computer.
