Alpenglow Certificate

A fast finality certificate produced by the Alpenglow consensus protocol when a supermajority of validators (66.7%+ of stake) have attested to a block through Votor's off-chain voting mechanism. Once an Alpenglow certificate is formed, the block is considered final, reducing finality time from Tower BFT's ~12.8 seconds to a target of under 150 milliseconds. Certificates are compact proofs of consensus that can be verified by any node.

Rama

Alpenglow

A next-generation consensus protocol proposed in SIMD-0326 that aims to collapse Solana's legacy systems (Proof of History, Tower BFT, gossip-based vote propagation) into two streamlined mechanisms: Rotor for data propagation and Votor for off-chain voting. Alpenglow targets reducing transaction finality from ~12.8 seconds to under 150 milliseconds, representing the most significant consensus overhaul in Solana's history.

Votor

The vote-optimized transaction ordering component of the Alpenglow consensus protocol. Votor handles off-chain voting and certificate generation, replacing Tower BFT's on-chain vote transactions that currently account for 70-80% of Solana's transaction volume. By moving voting off-chain and using a structured protocol for collecting and aggregating validator votes, Votor enables sub-second finality while freeing on-chain bandwidth for user transactions.

Finalidad

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.

Rama

Supermayoría

A threshold of more than 2/3 (66.7%) of total active stake agreeing on a particular fork. Supermajority is required for optimistic confirmation and, through sustained voting, for finality (rooting). If supermajority is lost (e.g., too many validators offline), the cluster halts until it recovers.

Protocolo Base

Prueba de Historia (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.

Protocolo Base

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

Bloque

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.
