Live on Solana testnet

VEXOR

An independent Solana validator. Written from scratch in Zig.

Its own pure-Zig cryptography, runtime and ledger: verified byte-for-byte against the reference implementation on every consensus change.

All figures above are self-measured against internal and reference-client fixture corpora; no external audit has yet reviewed these results.

Independently tracked

Don't take our word for it. validators.app is an independent Solana validator tracker, run by Block Logic, that continuously scores every validator on the network (skip rate, vote performance, stake, software version and data-center info), none of it sourced from us. Vexor's live testnet profile is public there.

Client diversity

From scratch, in Zig.

Not a fork. Not a re-skin. Vexor is an independent validator implementation: its own cryptography, its own runtime, its own ledger, sharing no code with the reference clients it must agree with.

A network is only as resilient as the number of ways it can be correct. Vexor is one more.

Proven, not promised

Verified byte-for-byte.

A consensus client is either bit-exact or it is wrong. Vexor is scored against two third-party conformance corpora (differentially, against the reference implementation), and every change to the live binary must first replay a full epoch of canonical slots to a byte-identical bank hash before it can ship.

Deploys are repro-gated, backed by self-recovery machinery that catches divergence instead of hoping it away.

The deploy gate, visualized

Nothing ships until it replays clean.

Candidate binaries re-execute canonical cluster history and must land on the exact same bank hash, slot for slot, before they are allowed near consensus.

The track so far

Shipped, in order.

  1. Testnet, live

    Voting on Solana testnet under its own identity.

  2. Pure-Zig cryptography

    Its own crypto stack, byte-correct against the reference.

  3. Conformance, lane by lane

    Differential scoring against two third-party fixture corpora: vote 100%, system 100%, syscall 99.62%.

  4. Vote hardening

    Consensus vote path closed out to byte-parity.

  5. Self-recovery

    In-process divergence detection and recovery machinery.

  6. Transaction-bearing in progress

    Producing blocks under real transaction load.

  7. Mainnet track planned

    The road from proven testnet parity to production.

Open source

Built in the open.

Parts of Vexor are developed and published as standalone libraries, useful on their own and open to the same scrutiny as the validator.

zbpf

A standalone sBPF virtual machine in Zig: the ELF loader, verifier, interpreter, syscalls, CPI, and native builtins. 1,065 / 1,065 tests, public CI green.

zolcrypt

Pure-Zig cryptography extracted from the validator: ed25519 (strict verification by default, matching Agave), secp256k1/r1, bn254, blake3, and the LtHash accumulator.

vexor-zig-sdk

An exploratory SDK for writing Solana on-chain programs in Zig, with a constraint DSL, IDL generation, and SPL bindings. 200 / 200 host tests; roadmap headlined by a compute-unit-exact test harness.
