Abstract: A method for tokenizing assets via a blockchain-to-blockchain bridge may include: receiving a first instruction from a client to mint first tokens for a client asset; encumbering the client asset on a custody ledger; creating a balance of the first tokens on a first distributed ledger; receiving a second instruction to lock and mint the first tokens to a second distributed ledger as second tokens; receiving verification from a custodian that the first tokens are locked on a lock ledger for the custodian; instructing a blockchain bridge computer program to mint second tokens to a client address on the second distributed ledger; receiving a third instruction to return the second tokens to the first distributed ledger; executing a public burn of the second tokens on the second distributed ledger; and instructing the custodian to unlock the first tokens and move the first tokens to the first distributed ledger.

Abstract: Systems, methods, and devices for decentralized notification services are disclosed. In some aspects, the techniques described herein relate to: providing a distributed notification service configured to execute on each node of a plurality of nodes of a decentralized peer-to-peer platform; determining, by the distributed notification service of a first node, a notification definition, where the notification definition is from a catalog of notification definitions and included in a distributed application executing on the first node; sending, by the distributed notification service of a second node, a notification message, where the notification message is associated with the notification definition; receiving, by the distributed notification service of the first node, the notification message; and delivering, by the distributed notification service of the first node, the notification message in the distributed application executing on the first node.

Abstract: A method for privacy preserving machine learning model sharing may include a computer program for a first institution of a plurality of institutions in a distributed ledger network: receiving transaction data for a transaction; training a local machine learning model using the transaction data; submitting parameters for the local machine learning model to the distributed ledger network as a private transaction with a trusted entity, wherein the trusted entity receives parameters for a plurality of local machine learning models from the distributed ledger network for the plurality of institutions in the distributed ledger network and aggregates the parameters into an aggregated machine learning model and submits the aggregated parameters to the distributed ledger network as one or more transactions; receiving, from the distributed ledger network, the aggregated parameters for the aggregated machine learning model; and updating the local machine learning model with the aggregated parameters.
