Crate solana_core

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

• accounts_hash_verifier
• admin_rpc_post_init
• banking_stage
  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_trace
• cache_block_meta_service
• 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”, also known as a Vec<Entry>, is received by the validator.
• consensus
• cost_update_service
  this service asynchronously reports CostTracker stats
• drop_bank_service
• fetch_stage
  The fetch_stage batches input from a UDP socket and sends it to a channel.
• gen_keys
  The gen_keys module makes lots of keypairs
• next_leader
• optimistic_confirmation_verifier
• poh_timing_report_service
  PohTimingReportService module
• poh_timing_reporter
  A poh_timing_reporter module implement poh timing point and timing reporter structs.
• repair
• replay_stage
  The replay_stage replays transactions broadcast by the leader.
• rewards_recorder_service
• sample_performance_service
• sigverify
  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_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 and on a GPU if perf-libs are available
• 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.
• tracer_packet_stats
• 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.
• verified_vote_packets
• voting_service
• warm_quic_cache_service
• window_service
  window_service handles the data plane incoming shreds, storing them in blockstore and retransmitting where required
