A high-performance distributed ledger and transaction computing network fabric over which large numbers of transactions are processed concurrently in a scalable, reliable, secure and efficient manner. In one embodiment, the computing network 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 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. The system also provides for confidence-based consensus and automated fork resolution. The approach enables the blockchain to continue operating in the presence of an underlying network outage, and to enable clients to make decisions about the disposition of transactions during any period of uncertainty before full consensus has been achieved.

In one embodiment, the computing network 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 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. The system also provides for confidence-based consensus. A configuration system is provided to enable configuration updates to be securely implemented across various subsets of the computing nodes.

High performance distributed system of record with ledger configuration system

A high-performance distributed ledger and transaction computing network fabric over which large numbers of transactions 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. Secure transaction processing is facilitated by storing cryptographic key materials in secure and trusted computing environments associated with the computing nodes to facilitate construction mining proofs during the validation of a block.

High performance distributed system of record with key management

A distributed ledger and transaction computing network fabric over which large numbers of transactions are processed concurrently in a scalable, reliable, secure and efficient manner. The computing network fabric or 'core' supports 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. The nodes operate on blocks independently from one another while still maintaining a consistent and logically-complete view of the blockchain as a whole. Secure transaction processing is facilitated by storing cryptographic key materials in trusted computing environments associated with the computing nodes to facilitate construction mining proofs during block validation.

High performance distributed system of record with distributed random oracle

A method operative in association with a set of transaction handling computing elements that 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 presence of a transaction recorded within a data block is verifiable via a cryptographic hash, and wherein Unspent Transaction Output (UTXO) data structures supporting the immutable chain of data blocks are maintained in a UTXO database, wherein a UXTO is an output from a finalized transaction that contains a value. The technique herein includes periodically snapshotting a given portion of the UTXO database to generate a hash. The hash of the snapshot is recorded within the immutable chain of data blocks, and preferably within a given block header. In responsive to a receipt of a recovery request, and to facilitate recovery of the system to a provably-known state, a consensus algorithm is executed over the UXTO snapshot.

High performance distributed system of record with unspent transaction output (UTXO) database snapshot integrity

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. According to another feature, secure transaction processing is facilitated by storing cryptographic key materials in secure and trusted computing environments associated with the computing nodes to facilitate construction mining proofs during the validation of a block.
