Abstract: In certain embodiments, model unlearning verifiability may be facilitated. In some embodiments, in connection with a request for unlearning of a dataset for a machine learning model, an unlearning process may be performed on the machine learning model, where the unlearning process involves multiple stages, for the unlearning of the dataset, at which model instances of the machine learning model are respectively generated. One or more proofs or hash-based values corresponding to the model instances may be generated, such as first and second hash-based values corresponding to first and second model instances of the machine learning model generated at first and second stages of the unlearning process, respectively (e.g., where the second stage depends on the first stage). The proofs or hash-based values may then be stored at one or more database locations of a database to enable verification of the performance of the unlearning process.
Abstract: Methods and system for managing partial private keys for cryptography-based, storage applications used in blockchain operations and/or facilitating secure authentication when conducting blockchain operations using cryptography-based, storage applications. For example, the methods and system may perform a plurality of blockchain operations for digital assets stored in a first cryptography-based, storage application, wherein the first cryptography-based, storage application corresponds to a first partial private key, and wherein the first partial private key is stored on a first user device, and wherein the second partial private key is not accessible to platform service facilitating the first cryptography-based, storage application.

Abstract: Methods and systems are described herein for performing cryptographic operations. In particular, the system receives identifiers for blockchain operation requests (e.g., bids) for transferring control of a non-fungible token (NFT) from a first blockchain address to a second blockchain address in exchange for payment (e.g., fungible tokens). The system provides visual indications of the blockchain operation requests to a first user device associated with a first cryptography-based storage application (e.g., an address associated with a cryptographic wallet of a user). The system may receive, from the first user device, a command to approve one of the blockchain operation requests and may determine an on-chain program (e.g., smart contract) for transferring the NFT. The system may submit, to the on-chain program, a request to transfer the NFT to the second blockchain address associated with the approved first blockchain operation request.
Abstract: Methods and systems are described herein for performing privacy-preserving operation of a system for acquiring non-fungible tokens (NFTs) using on-chain data. In particular, a user feed initialization system may determine that a privacy-preserving login is requested and may receive an on-chain address associated with a cryptography-based storage application (e.g., an address associated with a crypto wallet of a user) and determine, based on the on-chain address, NFTs that the user's cryptography-based storage application controls (e.g., NFTs that the user owns). The user feed initialization system may use on-chain data associated with the NFTs (e.g., via interrogating the on-chain programs associated with the NFTs that the user owns) to identify (e.g., via a machine learning model) other NFTs that the user may desire to acquire.
Abstract: Systems and methods for integration of components to facilitate executing transactions with different blockchain networks by using a standard API format. A standardized blockchain request identifying a blockchain network is received. The request is routed to a node synced with the blockchain network. A blockchain-specific call is constructed based on the standardized blockchain request. The blockchain network is interacted with using the blockchain-specific call. A response to the blockchain-specific call is returned in a standardized format.
Abstract: Systems and methods that mitigate network congestion on blockchain networks by supporting blockchain operations through off-chain interactions. For example, as communications to initiate off-chain events and/or blockchain operations are received, the system may determine various characteristics about the addresses involved. In particular, the system may determine whether the addresses correspond to cryptography-based, storage applications sharing a common platform service.

Abstract: Methods and systems described herein relate to an improved platform that provides secure, encrypted communications across distributed computer networks when coordinating cryptography-based digital repositories in order to perform blockchain operations in decentralized applications. More specifically, the methods and systems provide this improved platform by introducing additional abstraction layers into a production service for computing signatures during multi-party computation (MPC) signing procedures.

Abstract: Methods and systems for the use of multi-party computation (“MPC”) key systems that involve the use of multiple parties, each of which hold respective private data that may be used to evaluate a computation without ever revealing any of the private data held by each party to perform blockchain operations. Using the MPC key systems, the methods and systems generate secure, encrypted communications across distributed computer networks for authorizing use of cryptography-based digital repositories in order to perform blockchain operations in decentralized applications.
Abstract: Methods and systems for a processing architecture that maintains a separate logic pathway corresponding to a first operation type and a second operation type, until a blockchain operation is submitted to the blockchain network using either the first operation type or a second operation type. Following submission of the blockchain operation to the blockchain network, the architecture collapses the parallel logic pathways to a single logical pathway for both types.

Abstract: One or more aspects described herein provide methods and systems for authoritatively confirming that a recipient is an intended recipient to receive personal data, and to securely transmit the personal data to the intended recipient, when both the sender and receiver are operating in a trustless ecosystem such as that used with blockchain technology. A computing device may receive an indication of a blockchain address used, by a sender computing device and via a blockchain, to send one or more virtual assets. The computing device may store an association between the blockchain address and the recipient. The computing device may send, to the sender computing device and in response to a query comprising the blockchain address, an indication of the recipient. The indication may be configured to cause the sender computing device to send, to the recipient, personal data associated with an owner of the one or more virtual assets.

Abstract: A method for storing a cryptocurrency private key offline, including: encrypting the cryptocurrency private key using a primary encryption key; sharding the encrypted cryptocurrency private key into a plurality of alpha shards; generating beta shards by encrypting the alpha shards with secondary encryption keys; and storing representations of the beta shards offline. The method can additionally or alternatively include: retrieving the representations of the beta shards from the offline storage; decrypting the beta shards into the alpha shards based on the secondary encryption keys; reconstructing the encrypted cryptocurrency private key by recombining the alpha shards; and decrypting the encrypted cryptocurrency private key with the primary encryption key.
