Ed25519 Precompile

A native Solana program (address: Ed25519SigVerify111111111111111111111111111) that enables batch verification of Ed25519 signatures within on-chain program logic. Unlike the runtime's built-in transaction signature verification, this precompile allows programs to verify arbitrary Ed25519 signatures over arbitrary data, useful for off-chain message verification, oracle attestations, and multi-party protocols. Multiple signatures can be verified in a single instruction.

Ed25519

The elliptic curve digital signature algorithm used by Solana for all transaction signing. Ed25519 uses Curve25519 and produces 64-byte signatures with 32-byte public keys. Solana also provides an Ed25519 precompile program for on-chain signature verification within program logic.

Secp256k1 Precompile

A native Solana program (address: KeccakSecp256k11111111111111111111111111111) that verifies secp256k1 ECDSA signatures on-chain, enabling Ethereum-compatible signature verification within Solana programs. This precompile allows Solana dApps to verify signatures produced by Ethereum wallets (MetaMask, etc.), facilitating cross-chain identity verification, bridging, and interoperability without requiring users to create Solana-native keypairs.

Assinatura

A 64-byte Ed25519 digital signature over a transaction's message. Each signer in a transaction produces one signature. The first signature (from the fee payer) also serves as the unique transaction ID. Signature verification is parallelized in the TPU's sigverify stage using GPU acceleration.

Entrada

An ordered unit within a block containing a mix of PoH ticks and transaction batches. Each entry includes a PoH hash, a count of hashes since the previous entry, and zero or more transactions. Entries without transactions are tick entries that advance the PoH clock; entries with transactions prove those transactions occurred between two points in time.

Secp256r1 Precompile (P256)

A native Solana program for verifying ECDSA signatures on the secp256r1 (P-256/prime256v1) elliptic curve, enabling WebAuthn and passkey-based authentication directly on-chain. P-256 is the curve used by Apple Face ID/Touch ID, Android biometrics, and FIDO2 security keys. This precompile allows Solana dApps to authenticate users via device biometrics without managing traditional private keys, significantly improving wallet UX.

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.

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.
