Crate solana_core 

👎Deprecated since 3.1.0: This crate has been marked for formal inclusion in the Agave Unstable API. From v4.0.0 onward, the agave-unstable-api crate feature must be specified to acknowledge use of an interface that may break without warning.

The solana library implements the Solana high-performance blockchain architecture. It includes a full Rust implementation of the architecture (see Validator) as well as hooks to GPU implementations of its most paralellizable components (i.e. SigVerify). It also includes command-line tools to spin up validators and a Rust library

Modules

admin_rpc_post_initDeprecated

banking_stageDeprecated

The banking_stage processes Transaction messages. It is intended to be used to construct a software pipeline. The stage uses all available CPU cores and can do its processing in parallel with signature verification on the GPU.

banking_traceDeprecated

cluster_info_vote_listenerDeprecated

cluster_slots_serviceDeprecated

commitment_serviceDeprecated

completed_data_sets_serviceDeprecated

CompletedDataSetsService is a hub, that runs different operations when a “completed data set”, also known as a Vec<Entry>, is received by the validator.

consensusDeprecated

cost_update_serviceDeprecated

this service asynchronously reports CostTracker stats

drop_bank_serviceDeprecated

fetch_stageDeprecated

The fetch_stage batches input from a UDP socket and sends it to a channel.

forwarding_stageDeprecated

ForwardingStage is a stage parallel to BankingStage that forwards packets to a node that is or will be leader soon.

gen_keysDeprecated

The gen_keys module makes lots of keypairs

next_leaderDeprecated

optimistic_confirmation_verifierDeprecated

repairDeprecated

replay_stageDeprecated

The replay_stage replays transactions broadcast by the leader.

resource_limitsDeprecated

sample_performance_serviceDeprecated

sigverifyDeprecated

The sigverify module provides digital signature verification functions. By default, signatures are verified in parallel using all available CPU cores. When perf-libs are available signature verification is offloaded to the GPU.

sigverify_stageDeprecated

The sigverify_stage implements the signature verification stage of the TPU. It receives a list of lists of packets and outputs the same list, but tags each top-level list with a list of booleans, telling the next stage whether the signature in that packet is valid. It assumes each packet contains one transaction. All processing is done on the CPU by default and on a GPU if perf-libs are available

snapshot_packager_serviceDeprecated

staked_nodes_updater_serviceDeprecated

stats_reporter_serviceDeprecated

system_monitor_serviceDeprecated

tpuDeprecated

The tpu module implements the Transaction Processing Unit, a multi-stage transaction processing pipeline in software.

tvuDeprecated

The tvu module implements the Transaction Validation Unit, a multi-stage transaction validation pipeline in software.

unfrozen_gossip_verified_vote_hashesDeprecated

validatorDeprecated

The validator module hosts all the validator microservices.

voting_serviceDeprecated

warm_quic_cache_serviceDeprecated

window_serviceDeprecated

window_service handles the data plane incoming shreds, storing them in blockstore and retransmitting where required
