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 improved indexing of non-standardized, custom smart contracts. The improved indexer identifies custom landmarks (e.g., portions of bytecode indicative of custom smart contract transactions or particular functions in those transactions) that are indicative of transactions involving custom smart contracts (as well as the various attributes of those custom smart contracts). The indexer does this by first collecting bytecode for a subset of known transactions involving the custom smart contracts. The indexer then compares the bytecode of the custom smart contracts in the subset to identify the landmarks or probabilities that portions of the bytecode correspond to landmarks. Once these landmarks are identified (or a probability of the landmark is above a certain threshold), the indexer may designate these as known landmarks. The indexer may then compare the portion of the bytecode corresponding to the known landmark to raw bytecode.

Abstract: Systems and methods are described herein for novel uses and/or improvements to blockchains and blockchain technology. As one example, methods and systems are described herein for facilitating initial deployments of cryptographic assets across computer networks in a cryptographically secure manner while mitigating interactions with computer programs that simulate human activity.

Abstract: Aspects of the disclosure relate to processing cryptocurrency transactions. A computing platform may receive a transaction request. The computing platform may request SEKs from operator devices, and may receive requests to download encrypted SEKs accordingly. The computing platform may send the encrypted SEKs, and may receive corresponding decrypted SEKs from the operator devices in response. The computing platform may decrypt encrypted shares using the SEKs, and may use the decrypted shares to reconstruct a cryptographic signing key. The computing platform may validate the cryptographic signing key, and based on successful validation of the cryptographic signing key, may transfer authorize the requested transaction.

Abstract: Methods and systems are described herein for facilitating blockchain operations in decentralized applications by offering enhanced efficient when conducting blockchain operations using cryptography-based, digital ledgers through the use of specialized indexing. For example, as opposed to relying on raw blockchain data to power decentralized applications, the methods and systems use a blockchain indexer. The blockchain indexer provides a queryable record of a subset of blockchain operations.

Abstract: Methods and systems are described herein for a decision layer of a multi-layer data platform. The decision layer may process application queries and serve the queries based on a dataset of previously generated and indexed data or, as a last resort, queries the blockchain node directly. Using indexed blockchain data to serve application queries reduces latency and downtime of traditional systems that direct queries to blockchain nodes immediately. Furthermore, the decision layer overcomes high latency and downtime issues associated with a pool of load-balanced nodes by reducing the number of direct queries to a blockchain. When applications rely on data directly queried from a blockchain, they are susceptible to limited availability, a problem that the decision layer mitigates with indexed and updated blockchain data.

Abstract: Aspects of the disclosure relate to event processing. A computing platform may prefetch, prior to receipt of a purchase request, a plurality of pay to addresses (associated with an omnibus account, used to route funds from the omnibus account to a merchant account, and not associated with a particular merchant account when prefetched). The computing platform may receive, from a client, a request to make a purchase from a merchant, and may associate the client and the merchant with one of the prefetched pay to addresses/notify the client of the prefetched pay to address. The computing platform may monitor the prefetched pay to address for receipt of a predefined amount of cryptocurrency associated with the purchase. Upon detecting receipt of the predefined amount of cryptocurrency, the computing platform may transfer funds corresponding to the purchase from the omnibus account to an account for the merchant.

Abstract: Systems and methods for supporting both batch processing and streaming data applications, to load and process data incrementally, while providing a near-constantly materialized dataset based on raw blockchain data, are described. For example, the system may receive first on-chain data in a first format via a first input stream, wherein the first on-chain data originates from a blockchain node of a blockchain network. The system may transform the first on-chain data to a second format for storage in a second dataset, wherein the second format comprises an unbounded table.

Abstract: Methods and systems are described herein for recommending network processing routes when conducting blockchain operations. For example, the system may receive a first user request to perform a first blockchain operation across one or more computer networks to access a first blockchain asset. The system may then determine a first processing characteristic for the first user request and a first plurality of locations of the first blockchain asset (e.g., across the one or more computer networks). The system may then determine a first plurality of network routes to a first subset of the first plurality of locations. The system may then filter the first plurality of network routes (e.g., based on the first processing characteristic) to generate a first subset of the plurality of network routes. Based on the first subset of the plurality of network routes, the system may generate a first recommendation for performing the blockchain operation.

Abstract: A multitenant custodial wallet that provides users with a flexible primitive for managing discrete sets of cryptographic keys to interact with one or more blockchain protocols. By recognizing a pool primitive (e.g., pool object), a wallet can manage a set of keys as a single pool, in addition to managing keys individually.

Abstract: Systems and methods for a unified approach that is compatible with all blockchains, protocols, etc. The systems and methods use a bifurcated indexing system with a dynamically selected application service. The systems and methods bifurcate the indexing process into a storage layer and a compute layer.

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: Methods and systems are described herein for performing a cold start operation of a system for acquiring non-fungible tokens (NFTs) using on-chain data. In particular, a user feed initialization system 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: In certain embodiments, the use of re-usable cold storage keys to sign messages may be facilitated. In some embodiments, an offline computer system (operating within an offline computing environment) may obtain, from a removable computer-readable storage medium, signing key shards corresponding to a signing private key and a blockchain transaction to be signed, where the signing key shards satisfy a key shard threshold that is (i) a number of key shards required for reconstructing the signing private key and (ii) less than a number of key shards derived from the signing private key using a ceremony key. The offline computer system may form a ciphertext of the signing private key using the signing key shards and reconstruct the signing private key by decrypting the ciphertext using the ceremony key. The offline computer system may sign the blockchain transaction using the signing private key.

Abstract: In some embodiments, methods and systems use a client application that resides on a client device (e.g., comprising private and secure access credentials). Using the client application, a user may authorize and/or accept a plurality of configuration files. Upon acceptance, the client application is capable of connecting to any interface predefined in the plurality of configuration files (e.g., corresponding to a predetermined list of network systems). The configuration files is downloaded from a package repository or included during software installation.
