# Roadmap

This roadmap is the authoritative source for what ships when. The documentation covers what is live now; this page is the bridge to what is coming.

The roadmap is organized into three sections: Live now (what is shipping today, the phase-one product surface), Coming next (committed work, sequenced but not yet live), and Under exploration (capabilities being investigated but not yet committed).

## Live now

The following ship as the phase-one product surface and are documented in the live pages:

* **Z Inference Gateway** — single OpenAI-compatible API across four trust tiers (Anonymous, Private, TEE, End-to-End Encrypted).
* **Trust tiers** — cryptographically enforced; attestation verification mandatory before payload dispatch on Tiers 3 and 4.
* **Settlement rails** — Stripe (subscriptions and top-ups), x402 (per-request on Base and Solana with USDC), MPP (pre-authorized sessions).
* **Zero Completion Insurance** — first-class billing primitive applied uniformly across rails.
* **ShieldedPool** — multi-asset shielded pool on the host EVM chain.
* **Z Trade** — private trading venue.
* **Z Lend** — private lending market with USDZ and other bridged stablecoins.

## Coming next

The following are committed work, sequenced for release. The order reflects current planning; specific dates are not committed in this document.

### Z Chain and the validator network

* **Z Chain mainnet** — sovereign L1 with EVM compatibility. Migration target for ShieldedPool, Z Trade, and Z Lend.
* **Validator network** — permissionless validator operation under Zcash Satoshi Plus consensus.
* **Zcash Satoshi Plus (ZSP) consensus** — dual-staked by ZEC and Z.
* **Custom precompiles** — Equihash verification, Blake2b hashing, optimized Groth16 verifier.
* **Chain-native gas mechanics** — replacing the host-chain gas model.

### Chain-native utilities

* **USDZ** — chain-native stablecoin. Ships with Z Chain.
* **yUSDZ** — yield-bearing wrapper around USDZ.
* **Z Stake** — validator staking interface.

### Bridge stack

* **LayerZero bridge** — ERC-20 bridge to and from Z Chain at chain launch.
* **ZEC SPV bridge** — direct shielded ZEC deposits and withdrawals. Post-chain-launch.
* **FROST withdrawals** — threshold-signature-based withdrawals.

### SDK and developer tooling

* **TypeScript SDK** — primary Z-native SDK with full Tier 4 support.
* **Attestation verification endpoint** — raw TDX Quote exposed for independent verification.
* **Python SDK with Tier 4 support** — currently Python users access Tiers 1–3 via the OpenAI Python SDK.
* **Rust SDK.**
* **Go SDK.**
* **Mobile (iOS, Android) SDKs.**
* **Sidecar pattern:** a local proxy that lets OpenAI-compatible clients reach Tier 4 without using the Z SDK directly. Removes the SDK-language bottleneck on Tier 4.

### Inference platform

* **Community-hosted models** — open registry for models served by independent operators.
* **BYOK on Tier 1** — bring-your-own-key for enterprises with negotiated provider contracts. Architecturally rejected on Tiers 2, 3, and 4.
* **Long-lived Tier 4 sessions** — session continuity across mid-stream node failures, replacing the V1 hard-fail behavior.
* **Z Compute as a general developer surface** — the same verifiable-compute primitives that back the inference nodes, exposed for non-inference workloads.

### Additional Zcosystem utilities

* Prediction markets, adjudication and betting, and additional patterns dependent on outcome oracles.
* Additional primitives beyond Z Trade and Z Lend.

## Under exploration

The following are being investigated but are not yet committed to the roadmap. Inclusion here is informational; nothing in this list should be relied on by integrators.

* Native non-EVM execution environments.
* Inference-time fine-tuning as a first-class API surface.
* Federated learning beyond the long-term ambient capability.
* A dedicated DAO governance layer separate from the chain-native governance design.
* Additional TEE hardware vendors beyond those currently supported.
* Additional payment rails beyond Stripe, x402, and MPP.
