Abstract: Methods and systems are presented for providing a multi-party computation (MPC) framework for dynamically configuring, deploying, and utilizing an MPC system for performing distributed computations. Based on device attributes and network attributes associated with computer nodes that are available to be part of the MPC system, a configuration for the MPC system is determined. The configuration may specify a total number of computer nodes within the MPC system, a minimum number of computer nodes required to participate in performing a computation process, a key distribution mechanism, and a computation processing mechanism. Encryption keys are generated and distributed among the computer nodes based on the key distribution mechanism. Upon receiving a request for performing the computation, updated network attributes are obtained. The configuration of the MPC system is dynamically modified based on the updated network attributes, and the MPC system performs the computations according to the modified configuration.

Abstract: Methods and systems are presented for providing a secured framework for facilitating electronic transactions using a multi-party computation approach. Under the multi-party computation approach, the task of authenticating a transaction conducted through a user account is distributed among multiple computer nodes. One or more secrets and shares of a secret are distributed among the multiple computer nodes. An authentication process is implemented such that at least a portion of the multiple computer nodes, including one or more required nodes, exceeding a predetermined number of nodes are needed to perform a set of computations using the corresponding secret(s) and/or shares of the secret in order to generate a digital signature for the user account. By verifying the digital signature using a public key of the user account, it can be determined that the participation requirement has been satisfied.

Abstract: Quantum computers with a limited number of input qubits are used to perform machine learning processes having a far greater number of trainable features. A list of features of a field are divided into a plurality of feature groups. Each of the feature groups includes a respective group of some, but not all, of the features. A first machine learning process is performed to train a first instance of a quantum computer model, where the feature groups are used as inputs. Based on the first machine learning process being performed, a subset of the feature groups is selected for a second machine learning process. Thereafter, the second machine learning process is performed to train one or more second instances of the quantum computer model. The individual features of the selected subset of the feature groups are used as inputs for the second instances of the quantum computer model.

Abstract: Methods and systems are presented for providing a framework for facilitating multi-party computation within a sharding environment. After a blockchain is divided into multiple shard chains, a multi-party computation system obtains attributes associated with a first shard chain. The attributes may represent characteristics of the first shard chain, characteristics of transactions recorded in the first shard chain, and characteristics of the computer nodes configured to manage the first shard chain. Based on the attributes, the multi-party computation system determines a multi-party computation scheme that specifies a minimum threshold number of nodes required to participate in a transaction validation process and at least one required node required to participate in the transaction validation process for the first shard chain. The multi-party computation system configures the computer nodes configured to manage the first shard chain to perform the transaction validation process according to the multi-party computation scheme.
