Abstract: A decentralized node may generate a network of decentralized nodes individually configured to store, receive, and transmit data based on rules associated with the decentralized nodes. A decentralized node may associate a decentralized identity of an entity with a select decentralized node of the decentralized nodes. A decentralized node may present a user interface including one or more access controls at a edge device, the access controls configuring rules to be applied to third-party access and modification of decentralized identity data associated within the decentralized identity of the entity and stored at the selected decentralized node. A decentralized node may identify the decentralized identity data accessible to the select decentralized node based on the rules. A decentralized node may store the decentralized identity data within the decentralized identity associated with the entity at the select decentralized node.

Abstract: Systems and methods for processing events transmitted by an application to hashing processors executing a custom mempool protocol that is independent of the public blockchain protocol. Events transmitted by the application are hashed only into blocks with other events transmitted by the application or events with parameters satisfying a screening criterion and are not propagated to mempools of nodes that are not executing the custom mempool protocol. The blocks are appended to the blockchain according to the public blockchain protocol. Thus, application users exercise intentionality over which hashing processors process their events and which other events will be hashed into a block with the users' events.

Abstract: Some embodiments disclose the use of zero-knowledge proofs (ZKPs) to prevent or at least mitigate privacy compromises that can occur to transactions conducted on distributed ledger-based networks (DLNs). In particular, some embodiments disclose methods and systems where ZKPs can be used to keep confidential or at least mitigate public revelation of private transaction data due to the analyses of the transaction fee or gas paid to facilitate the transaction on the DLN.

Abstract: The disclosed embodiments include methods and systems for providing tokenized transaction accounts. In one embodiment, a computer-implemented method is provided that may include generating, by one or more processors, a first tokenized transaction account from a first transaction account associated with a first user. The method may also include providing the first tokenized transaction account to a client device associated with the first user for storage in the client device and use in transactions. The method may also include updating the first tokenized transaction account based on one or more conditions and providing the updated first tokenized transaction account to the client device for storage and use in a subsequent transaction.

Abstract: The present disclosure relates to blockchain-based data processing methods and devices to achieve balance between a service need and system resource consumption. In one example method, an amount of service data processed by consensus in a blockchain in a specified time period is monitored. A determination is made as to whether the monitored amount of processed service data in the specified time period is less than a specified first threshold or more than a specified second threshold. In response to determining that the monitored amount of processed service data in the specified time period is less than the specified first threshold or more than the specified second threshold, a block generation time for the blockchain is dynamically adjusted. A new block in the blockchain is then dynamically adjusted based on the adjusted block generation time.

Abstract: A virtualized blockchain forest includes a plurality of individual blockchains. Each individual blockchain of the plurality includes a blockchain height, a genesis block, and at least one additional block. The virtualized blockchain forest further includes a plurality of participating processors that make up a consensus pool, and a blockchain forest height having a time-sequenced start-to-finish length of blocks among the collective plurality of individual blockchains. The virtualized blockchain forest is configured to aggregate different ones of the plurality of individual blockchains, and is further configured to terminate individual ones of plurality of individual blockchains.

Abstract: Apparatus, systems and methods improve efficiency in transacting a swap or other futures based financial instrument, by using time-weighted index averages to decrease counterparty settlement risk. In preferred embodiments related to Bitcoin and several other cryptocurrencies, the swaps are based upon a time-weighted index average (Dwa) of multiple instances of difficulty (Dx to Dy) of mining the cryptocurrency over multiple time periods (Px to Py) where both Ds and Ps are available from the decentralized public blockchain. Traders can use these time-weighted index averages in conjunction with the anticipated values of Ds and Ps for the remainder of the duration of the index, to calculate the index value at any given time. The index can be used to increase or decrease mining of digital assets, or switch allocation of resources between mining different digital assets.
