The number of blocks produced in the ledger since the genesis block. Block height increments only for slots that successfully produce a block (skipped slots do not increment it), so block height is always less than or equal to the current slot number. Block height is accessible via the getBlockHeight RPC method and the Clock sysvar.

Altura do Bloco (block-height) Categoria: Protocolo Base Definição: The number of blocks produced in the ledger since the genesis block. Block height increments only for slots that successfully produce a block (skipped slots do not increment it), so block height is always less than or equal to the current slot number. Block height is accessible via the getBlockHeight RPC method and the Clock sysvar. Relacionados: Bloco, Slot, Bloco Gênesis

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.
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.
The first block (slot 0) of a Solana cluster that defines initial configuration: the mint account, initial token supply, built-in program deployments, and cluster parameters. The genesis config is generated by the `solana-genesis` tool and shared among all validators to bootstrap a new cluster.

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.
The process of distributing a newly produced block from the leader to all validators in the cluster. Solana uses Turbine for fast propagation—the leader shreds the block, erasure-codes the shreds, and feeds them into the Turbine tree. Target propagation latency is under 200ms for the full cluster.
The first block (slot 0) of a Solana cluster that defines initial configuration: the mint account, initial token supply, built-in program deployments, and cluster parameters. The genesis config is generated by the `solana-genesis` tool and shared among all validators to bootstrap a new cluster.

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.
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).
