Embodiments herein describe a hardware accelerator for a blockchain node. The hardware accelerator is used to perform a validation operation to validate one or more transactions before those transactions are committed to a ledger of a blockchain. The blockchain may include multiple peer-nodes, each of which contains standard software running on a server or container. Instead of validating a block of transactions using software, the hardware accelerator can validate the transactions in a fraction of the time. The peer-node software then gathers the validation results from the hardware accelerator and combines the results with received block data to derive the block which is committed to the stored ledger.

Blockchain machine compute acceleration engine with a block verify and a block validate

Embodiments herein describe a hardware accelerator (e.g., a network acceleration engine) for a blockchain machine or node. The hardware accelerator parses packets containing separate components of a block of transactions to generate data to perform a validation process. To avoid the latency that comes with using software, the embodiments herein describe a protocol processor in the hardware accelerator that parses the packets and prepares the data so it can be consumed by downstream components in the accelerator without software intervention. These downstream components can then perform a validation operation to validate one or more transactions before those transactions are committed (i.e., added) to a ledger of a permissioned blockchain.

Blockchain machine network acceleration engine

Examples herein describe an acceleration framework that includes a hybrid congestion control (CC) engine where some components are implemented in software (e.g., a CC algorithm) while other components are implemented in hardware (e.g., measurement and enforcement modules and a flexible processing unit). The hardware components can be designed to provide measurements that can be used by multiple different types of CC algorithms. Depending on which CC algorithms are currently enabled, the hardware components can be programmed to perform measurement, processing, and enforcement tasks, thereby freeing the CPUs in the host to perform other tasks. In this manner, the hybrid CC engine can have the flexibility of a pure software CC algorithm with the advantage of performing many of the operations associated with the CC algorithm in hardware.

Programmable congestion control engine

Mining proxy acceleration may include receiving, within a mining proxy, packetized data from a mining pool server and determining, using the mining proxy, whether the packetized data qualifies for broadcast processing. In response to determining that the packetized data qualifies for broadcast processing, the packetized data can be modified using the mining proxy to generate broadcast data. The broadcast data can be broadcast, using the mining proxy, to a plurality of miners subscribed to the mining proxy.

Mining proxy acceleration

A device includes a programmable passive measurement hardware engine, a programmable active measurement hardware engine, and a configuration engine. The programmable passive measurement hardware engine is configured to collect statistical data, from data transmission at a network line rate, used for network measurement. The programmable active measurement hardware engine is configured to generate probe packets and wherein the programmable active measurement hardware engine is further configured to collect responses to the generated probe packets, wherein the collected responses are used for the network measurement. The configuration engine is configured to receive data settings and wherein the configuration engine is further configured to program the programmable passive measurement hardware engine and the programmable active measurement hardware engine with the received data settings.
