A novel structured random sample consensus protocol to greatly improve blockchain and distributed ledger technology throughput and scalability, while maintaining decentralization and high levels of security. The invention leverages small committees of fixed sizes, called “Clans,” threshold cryptography, and logical virtual districts, called “Tribes,” in order to deterministically random sample disparate nodes for sentiment analysis on a transactions validity, thereby only requiring a relatively small subset of nodes to validate any particular transaction or batch of transactions thus enabling much greater concurrency and parallel processing compared to other more linearized consensus algorithms, while maintaining high security.

A system can correct or avoid an unexpected result caused by executing a smart contract. The system can detect a potential/actual result generated based on a primary smart contract, which is stored in association with a block of a blockchain and is configured to execute when a predetermined condition is satisfied. The system can determine that the potential/actual result deviates from an expected result and, in response, retrieve a secondary smart contract from a repository. The secondary smart contract is selected to prevent the unexpected result in the future. The system can store the secondary smart contract retrieved from the repository in association with a subsequent block of the blockchain. The primary smart contract and the secondary smart contract are then configured to execute in concert when the predetermined condition is satisfied such that the expected result is produced instead of the unexpected result.

Systems and methods for enrolling and authenticating a user in an authentication system via a camera of a computing device include capturing and storing biometric information from at least one first image and at least one second image of the user taken via the camera. Prior to use, the user answers personal questions and the answers are stored as stored answer data. Later, such as at a business, the questions are presented to the user and the user provides their personal answers via a computing device. The answers are processed and uploaded to an authentication server where a comparison occurs against the stored answer data. If a match does not occur, then the authentication/identity verification processes ends. If a match does occur, then the authentication process continues. The questions match may serve as a gate function for accessing authentication data stored in a blockchain.

Improved Simplified Payment Verification (SPV) solutions for blockchain-implemented transfers are presented and can be implemented in one or more SPV wallets, or on smart cards etc. that can enable Alice to transfer an asset to Bob. Bob sends Alice a payment transaction template (template Tx3) and requests: the full transaction data for all input transactions (Tx1, Tx2) comprising at least one output that Alice wants to spend as inputs to a transfer (Tx3); the Merkle path for all input transactions (Tx1, Tx2) linking them to their respective Merkle roots associated with their respective block headers; the completed transfer transaction (Tx3). Alice provides this information plus her signature and optionally a change address. Bob can then perform local SPV checks using transactions Tx1 and Tx2, their corresponding Merkle paths Path 1, Path 2, and Bob's local list of block headers. Bob broadcasts the transfer transaction (Tx3) to the P2P network.

Example data processing methods are apparatus are described. In one example method, a system includes a plurality of data management apparatuses, and each data management apparatus corresponds to one blockchain node in a blockchain network. The method includes receiving, by a target data management apparatus in the plurality of data management apparatuses, a transaction request from a blockchain client, where the transaction request includes identifiers of transaction participants. The target data management apparatus performs input/output (I/O), in the blockchain network based on the transaction request, on a transaction information ciphertext. The transaction information ciphertext is obtained by encrypting a transaction information plaintext by using a key that is invisible to a participant other than the transaction participant. The target data management apparatus then returns a transaction result to the blockchain client.

A computer system operates an off-chain electronic game that includes in-game assets stored off of a blockchain. The computer system detects an occurrence of a progression event related to a particular in-game asset associated with a particular player. In response to the occurrence, the computer system increases an upgrade capacity of the particular in-game asset. The upgrade capacity controls a maximum number of attribute upgrades that can be applied to the particular in-game asset at a time. The computer system then permits or prevents application of attribute upgrades to the particular in-game asset based on the upgrade capacity. The computer system further permits or prevents application of attribute upgrades based on whether the attribute upgrades are being applied to other off-chain electronic games. An interoperability API is used to determine whether a given attribute upgrade is being used in another game.
