Confirmation

A vote by a validator on a block, weighted by the validator's stake. The more stake-weighted confirmations a slot receives, the higher the confidence it will be finalized. RPC methods accept commitment levels (processed, confirmed, finalized) to specify the required confirmation threshold.

Grafo conceitual

Veja o termo como parte de uma rede, não como uma definição sem saída.

Esses ramos mostram quais conceitos esse termo toca diretamente e o que existe uma camada além deles.

Ramo

Finalidade

The guarantee that a transaction cannot be reversed. Solana offers two levels: optimistic confirmation (~400ms, 66.7%+ stake voted) and full finality (~12-13 seconds, 31+ confirmations rooted). Once a slot is rooted, its transactions are irreversible under the assumption that no more than 1/3 of stake is malicious.

Ramo

Confirmação Otimista

A transaction confirmation level achieved when 66.7%+ of total stake has voted on the slot, typically within ~400ms. Optimistic confirmation provides high probability of finality without waiting for full root depth. It corresponds to the 'confirmed' commitment level in RPC queries.

Protocolo Base

Confirmed Block

A block that has received votes from validators representing a supermajority (66.7%+) of the cluster's active stake, achieving optimistic confirmation. Confirmed blocks are highly likely to be finalized but are not yet irreversible — full finality requires the block to become rooted through 31+ consecutive confirmations in Tower BFT.

Protocolo Base

Prova de História (PoH)

A clock mechanism that cryptographically proves the passage of time between events. PoH uses a sequential SHA-256 hash chain where each output becomes the next input, creating a verifiable ordering of events without requiring consensus. The leader produces ~400,000 hashes per slot (~400ms), and any validator can verify the sequence in parallel, enabling Solana's high throughput by removing the need for validators to agree on time.

Cluster

A set of validators working together to maintain a single Solana ledger. Solana operates three main clusters: mainnet-beta (production), devnet (development), and testnet (stress testing). Each cluster has its own genesis block, token supply, and independent validator set. Validators in a cluster discover each other via the gossip protocol.

Tower BFT

Solana's custom BFT consensus algorithm built on top of Proof of History. Tower BFT uses PoH as a clock to reduce communication overhead in traditional PBFT from O(n²) to O(n). Validators vote on forks with exponentially increasing lockout periods—each consecutive vote doubles the lockout, making rollbacks progressively more expensive. A fork is finalized when it reaches supermajority (66.7%+ of stake).

Protocolo Base

Slot

A time window during which a designated leader validator can produce a block. Each slot lasts approximately 400 milliseconds. Slots are numbered sequentially from genesis and grouped into epochs of 432,000 slots (~2-3 days). Not every slot produces a block—a skipped slot means the leader was offline or too slow.

Protocolo Base

Bloco

A set of entries produced by a leader during a single slot. A block contains transactions bundled into entries, each with a PoH hash proving ordering. Blocks are broken into shreds for network propagation via Turbine. Maximum block size is limited by compute units (48M CU cap per block) rather than byte size.
