Patent number: 11888991Abstract: Different communication and software protocols may be used by different blockchain networks. Cross-chain communication is provided via a software bridge configured to enable specific operations. An event request may be sent from a first blockchain network to a second blockchain network. The event request may be processed using a first protocol of the first network to provide a first output. An offer of equivalent processing provided by the second network may be verified by: processing the event request using a second protocol of the second network to provide a second output, and confirming that the second output matches the offer of equivalent processing. A processing equivalence of the event request may be established between the first network and the second network based on the first output of the event request processed using the first protocol and the second output of the event request processed using the second protocol.Type: GrantFiled: August 25, 2021Date of Patent: January 30, 2024Assignee: PAYPAL, INC.Inventors: Michael Jim Tien Chan, Oluwatomisin Olayemi Jenrola, Vladimir Bacvanski, John Lucas Timoney, Daniel Santiago Rincon Silva, Aklen Altanel, Liam Julian DiGregorio, Suryatej Gundavelli

Publication number: 20230291544Abstract: Methods and systems described herein may implement non-fungible tokens that implement a programmable grammar-based syntax in a variety of environments. In an embodiment, a first non-fungible token that implements a programmable grammar-based syntax standard and includes a first updatable programmable section is generated. The first non-fungible token includes at least one of first executable instructions or first data, and a first portion of the at least one of the first executable instructions or the first data is stored, according to the grammar-based syntax standard, in the first updatable programmable section. The first non-fungible token may then be stored at a first blockchain address on a blockchain, and the first portion of the at least one of the first executable instructions or the first data in the first updatable programmable section of the first non-fungible token is subsequently changed to at least one of second executable instructions or second data.Type: ApplicationFiled: April 4, 2023Publication date: September 14, 2023Inventors: Bradley Turner, Michael Jim Tien Chan, Jonathan Michael Padilla, Liam Julian DiGregorio, Charles Gabriel Neale Dalton

Publication number: 20230186281Abstract: Novel technical ways of facilitating secured execution of blockchain transactions are presented. In various embodiments, a system, comprises a non-transitory memory comprising instructions; and one or more hardware processors coupled to the non-transitory memory and configured to read the instructions to cause the system to perform operations comprising: detecting a request from a first user to access one or more digital assets of a first digital wallet of a second user; in response to detecting the request, determining whether to provide access to the one or more digital assets to the first user based on one or more factors, wherein the one or more factors includes a location of the first user, a location of the second user, or one or more characteristics of the first user; and restricting the first user from accessing the one or more digital assets based on the one or more factors.Type: ApplicationFiled: December 10, 2021Publication date: June 15, 2023Inventors: Michael Charles Todasco, Mehak Jethmalani, Liam Julian DiGregorio

Publication number: 20230177489Abstract: Novel technical ways of facilitating secured execution of blockchain transactions are presented. In various embodiments, A system, comprising a processor and a non-transitory computer-readable medium having stored thereon computer-executable instructions that are executable by the processor to cause the processor to perform operations comprising: receiving a set of biometric identifiers; in response to receiving the set of biometric identifiers, validating the set of biometric identifiers; in response to validating the set of biometric identifiers, encoding, using a synthesizer, the set of biometric identifiers with a digital-key to generate a multi-factor signature; and causing a block-chain transaction to be executed using the multi-factor signature.Type: ApplicationFiled: December 8, 2021Publication date: June 8, 2023Inventors: Michael Jim Tien Chan, Suryatej Gundavelli, Charles Gabriel Neale Dalton, Michael Charles Todasco, Mehak Jethmalani, Liam Julian DiGregorio, John Lucas Timoney

Publication number: 20230040773Abstract: Mechanisms for efficiently transferring multiple unspent transaction output (UTXO) tokens in a blockchain network operating a UTXO-based token transaction model are disclosed herein. These methods allow for the use of less computer processing and network bandwidth resources in the transfer of blockchain items, particularly in blockchain schemes with lineage tracking mechanisms (e.g. as may allow for clawback of tokens). Some embodiments comprise generating a delegated account and transferring the UTXO tokens into the delegated account. The ownership of the delegated account can then be transferred to another use of the blockchain network in a single transaction, thereby avoiding the need to individually transfer the UTXO tokens and incur the memory and computational resource burden and costs associated with therewith.Type: ApplicationFiled: October 24, 2022Publication date: February 9, 2023Inventors: Charles Gabriel Neale Dalton, Liam Julian DiGregorio

Patent number: 11449938Abstract: Tracking and clawing back unspent transaction output (UTXO) tokens mechanism are disclosed for distributed ledger technology-based networks (DLTNs) operating a UTXO-based token transaction model (which can include blockchain networks). Some embodiments comprise receiving a request to transfer a UTXO token in a DLTN operating a UTXO-based token transaction model. Further, the embodiments can include determining that a clawback list includes the genesis token identifier and barred token identifiers of UTXO tokens barred from being transferred on the DLTN. In addition, the embodiments can include determining whether the clawback list includes any of the ancestral token identifiers of the UTXO token and generating an instruction regulating the transfer of the UTXO token in the DLTN based on the determining whether the clawback list includes any of the ancestral token identifiers. Such techniques improve the security and functionality of DLTNs such as a blockchain network.Type: GrantFiled: December 23, 2020Date of Patent: September 20, 2022Assignee: PAYPAL, INC.Inventors: Charles Gabriel Neale Dalton, Liam Julian DiGregorio
