Abstract: A high-performance distributed ledger and transaction computing network fabric over which large numbers of transactions (involving the transformation, conversion or transfer of information or value) are processed concurrently in a scalable, reliable, secure and efficient manner. In one embodiment, the computing network fabric or "core" is configured to support a distributed blockchain network that organizes data in a manner that allows communication, processing and storage of blocks of the chain to be performed concurrently, with little synchronization, at very high performance and low latency, even when the transactions themselves originate from distant sources. This data organization relies on segmenting a transaction space within autonomous but cooperating computing nodes that are configured as a processing mesh. Each computing node typically is functionally-equivalent to all other nodes in the core. The nodes operate on blocks independently from one another while still maintaining a consistent and logically-complete view of the blockchain as a whole.

Abstract: A payment network comprises ledger services, and associated wallet services. To provide wallet services resiliency, multiple active wallet replicas are used to enable the system (i) to rely on collision detection and blockchain idempotency to produce a single correct outcome, and (2) to implement various collision avoidance techniques. Using a ledger services idempotency feature, multiple actors form independent valid intents and know that no more than one intent will get finalized on the ledger. In a variant embodiment, replicas implement processing delays and utilize so-called "intent" messages. By adding the delays, decision logic is biased logic towards one intent. The. intent messages are used to intercede before a wallet handles a same original upstream message and forms a different intent. Seeing the replica's intent, the wallet can adopt the same intent and proceed with downstream processing. After adopting intent, preferably a wallet also informs its replicas of its intent.

Abstract: Transaction handling computing elements comprise a network core that processes transaction requests into a blockchain, wherein a data block is a collection of transactions, and wherein an Unspent Transaction Output (UTXO) supporting the blockchain is an output from a finalized transaction. The elements interoperate with a transaction signing mechanism that associates a set of addresses on the blockchain with a delegate address, the delegate address having a set of signing public keys corresponding to one or more signing private keys used to sign UTXOs. In association with a new transaction being processed by the set of transaction handling components, a signing public key for an associated UXTO is located by following an address chain that includes an address in the set of addresses together with the delegate address. The signing public key is retrieved from a location associated with the delegate address and then used to sign (unlock) the associated UXTO.

Abstract: A set of transaction handling computing elements comprise a network core that receive and process transaction requests into an append-only immutable chain of data blocks, wherein a data block is a collection of transactions, and wherein an Unspent Transaction Output (UTXO) data structure supporting the immutable chain of data blocks is an output from a finalized transaction. Typically, the UTXO data structure consists essentially of an address and a value. In this approach, at least one UTXO data stmcture is configured to include information either in addition to or in lieu of the address and value, thereby defining a Transaction Output (TXO). A TXO may have a variety of types, and one type includes an attribute that encodes data. In response to receipt of a request to process a transaction, the set of transaction handling computing elements are executed to process the transaction into a block using at least the information in the TXO.
