    Abstract: A fully-parallelized, highly-efficient compositional implicit hydrocarbon reservoir simulator is provided. The simulator is capable of solving giant reservoir models, of the type frequently encountered in the Middle East and elsewhere in the world, with fast turnaround time. The simulator may be implemented in a variety of computer platforms ranging from shared-memory and distributed-memory supercomputers to commercial and self-made clusters of personal computers. The performance capabilities enable analysis of reservoir models in full detail, using both fine geological characterization and detailed individual definition of the hydrocarbon components present in the reservoir fluids.

    Abstract: In this disclosure, a method for the update of a distributed ledger of a cryptocurrency is presented whereby transaction data need only be broadcasted once in the cryptocurrency network, thereby reducing the bandwidth consumption of the consensus nodes in the network. This is achieved with a two-stage process where in the first stage, a consensus is reached on the transactions that were received from every consensus node in the network. In the second stage, each consensus node uses an identical predefined protocol to obtain a subset of transactions from the total set reached in the first stage, with the predefined protocol being any systematic and deterministic way of obtaining the subset of transactions that are valid such that no cryptocurrency address is overdrawn. A consensus is then reached by the network on the state of the updated ledger after inclusion of this subset of transactions in the distributed ledger.

    Abstract: In this disclosure, a method for the system of operation of a decentralized staking pool within a proof-of-stake cryptocurrency framework is presented. Stakeholders of a staking pool do not send their stakes to the staking pool. Instead, their association with the staking pool is validated and recorded by other nodes in the cryptocurrency network. Stakeholders who cannot afford expensive computing infrastructure may still participate via the staking pool in a high-throughput and dense network capable of processing tens of thousands of transactions per second with fast transaction confirmation times not limited by long message relay times over a broad and sparse network. After a staking pool has been accepted into the network, it may start validating transactions and participating in the consensus of the distributed ledger, with regular updates of its list of stakeholders to the network, as well as the crediting of transaction fees to its stakeholders.
