Crate solana_core 

The solana library implements the Solana high-performance blockchain architecture. It includes a full Rust implementation of the architecture (see Validator)). It also includes command-line tools to spin up validators and a Rust library

Modules

admin_rpc_post_init

banking_simulation

banking_stage

The banking_stage processes Transaction messages. It is intended to be used to construct a software pipeline.

banking_trace

cluster_info_vote_listener

cluster_slots_service

commitment_service

completed_data_sets_service

CompletedDataSetsService is a hub that runs different operations when a completed data set is received by the validator.

consensus

cost_update_service

this service asynchronously reports CostTracker stats

drop_bank_service

epoch_specs

fetch_stage

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

forwarding_stage

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

gen_keys

The gen_keys module makes lots of keypairs

next_leader

optimistic_confirmation_verifier

repair

replay_stage

The replay_stage replays transactions broadcast by the leader.

resource_limits

sample_performance_service

sigverify

The sigverify module provides digital signature verification functions. By default, signatures are verified in parallel using all available CPU cores.

sigverify_stage

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.

snapshot_packager_service

staked_nodes_updater_service

stats_reporter_service

system_monitor_service

tpu

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

tvu

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

unfrozen_gossip_verified_vote_hashes

validator

The validator module hosts all the validator microservices.

vote_simulator

voting_service

warm_quic_cache_service

window_service

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