Resumen de: US2024273516A1
A method and a system for multi-factor authentication for blockchain services, the method comprising holding, by an authentication server, an account of an end-user identifiable via an accountID; establishing, by the end-user, a multi-factor approval status in the server; and in response to an operation to be performed in a customer smart contract, the latter interacting with the server to confirm the established multi-factor approval status. The interacting step comprises checking whether a mapping between a public key and the accountID exists; calling a function in SDK and performing an in-chain call to a function OracleRequest; performing a gas payment and emitting an event with the accountID and an integer as parameter; executing a task identified by the integer, the task performing an API call to an oracle interaction backend that further calls a checkStatus API; performing a call to a function fullfillOracleRequest2, and further propagating the established multi-factor approval status to the customer smart contract.

A transient blockchain proxy server consolidates many individual requests to add data to a blockchain by aggregating hashed data from these requests and sending the aggregated hashed data to the blockchain network as a single request. The blockchain network adds a new block to the blockchain with the aggregated hashed data and returns a transaction identifier for the new block to the transient blockchain proxy server, which passes the transaction identifier back to all the requestors who then can directly use the blockchain network to verify the hashed data using the transaction identifier. The transient blockchain proxy server buffers all incoming requests until one of the pending requests reaches a send timepoint that is the blockchain network delay plus a buffer time before a guaranteed time of verification. All incoming requests are then consolidated and sent as a single transaction to the blockchain network. Tiered verification-time services are enabled.

A crypto ETP is administered by a portfolio modeling computer/(PMC), a fund administration computer/(FAC), an order taking platform computer/(OTP), a custodian computer/(CC), and a paying agent settlement computer/(PASC). The PMC defines the ETP and captures data for a cryptocurrency index. The CC tracks Underlying Assets held by the ETP, and sends the data to the FAC, which calculates the NAV of the Underlying Assets to generate a Portfolio Composite File/(PCF) sent to the OTP. The OTP receives and validates/confirms with the CC, orders for creations and redemptions of the ETP from Authorized Parties/(APs), in exchange for the Underlying Assets and/or cryptocurrency. The PASC provides settlement on the Exchange in cryptocurrency by: receiving confirmation from the CC of transfer of underlyings, ETPs or cryptocurrency from the APs to a blockchain wallet associated with the PCM; and issuing units of the ETPs, underlyings or cryptocurrency to the APs.
