Abstract: Systems and methods are disclosed for security through multi-party computation (MPC). In some examples, a system generates, at a first device and using a first private key share (of a plurality of private key shares). The plurality of private key shares each correspond to different devices. The system receives, from one or more additional devices, one or more additional partial signatures that are generated using one or more additional private key shares (of the plurality of private key shares). The system identifies that a total amount of partial signatures associated with the transaction is meets or exceeds a minimum threshold amount of partial signatures. The system aggregates the first partial signature and the one or more additional partial signatures to generate a signature, and facilitates processing of a transaction using the signature and a distributed ledger.

Abstract: A system for managing and using digital financial assets, such as cryptocurrency uses multiple independent devices that mutually cooperate to control cryptocurrency assets in a secure manner. Each of these devices may store a unique private key associated with the cryptocurrency assets, which may be configured such that a certain minimum number of these private keys are required to transfer the cryptocurrency assets. The use of multiple private keys spread across multiple distinct devices may reduce the likelihood of loss stemming from a hardware failure or reduce the likelihood of an attacker successfully gaining access to the cryptocurrency assets. In addition, selection of the devices to be used for storing these private keys, as well as how many private keys are required to authorize a transaction, may be tailored to balance a user's preferences for reliability of access versus security and for third-party custody versus self-custody.

Abstract: A system for locally authenticating a transaction of digital financial assets, such as cryptocurrency. A first device may locally store financial assets in non- volatile memory of the first device. The first device may use the locally-stored financial assets to conduct a local transaction with a second device. The first device may generate a transaction settlement data token and exchange the token with the second device, wherein the transaction settlement data token includes information specific to the local transaction, a value associated with the local transaction, and encrypted personal information associated with the first device. After receiving a confirmation of transmission from the second device, the value associated with the local transaction may be debited from the locally-stored financial assets.

Abstract: Liquidity and security mechanism are described as part of a unified cryptographic wallet. In an implementation, a request is received by a server to initiate a transaction involving a fund transfer using a blockchain network or a decentralized network. A determination is made, automatically and without user intervention, whether to perform the transaction, e.g., based on a threshold. The request responsive to determining to perform the transaction. The signed request is communicated to initiate the fund transfer of the transaction using the blockchain network or the decentralized network.
