This is the one section that changes. Everything above describes XChain's durable design and vision — it stays valid as the network grows. Here live the parts that move over time: what is running today, what is in progress, the roadmap, and the network read straight from the chain — so those numbers never go stale. If any sentence here ever looks dated, the live panel is the ground truth.

The live network

Reading network status from www.xscan.org…

Read directly from www.xscan.org/rpc|lcd/aN (CORS open, so it loads in your browser). If the network is briefly unreachable, a link to the explorer is shown instead of stale numbers. The fault-tolerance verdict is derived from the live power distribution — with two validators where the largest holds more than a third, losing it halts the chain; add nodes until each holds no more than a third and the verdict flips automatically. No node/validator count is hardcoded anywhere in these docs — this panel is the single source.

What is real today

✅ Here now — running, and verifiable by anyone. The Testnet MVC is live on real infrastructure (current node/validator set and fault tolerance in the panel above). 6 of the 7 primitives are real on-chain modules (UIR, UAC, XMP, DA, VLC, SC); the MVC acceptance passes end-to-end on real nodes + a real relayer. The explorer www.xscan.org reads chain-id and denom at runtime.

🟡 In progress / stand-ins — stated plainly.

On the live network, the prover is still pure MOCK. ProofSystem.MOCK is blocked off-testnet by a fail-closed chain-id guard. A real Groth16/BN254 verify exists on a code branch (behind a stand-in circuit MiMC(prev,tx,new), ~164-byte proof) — but it is not on the running chain, and not yet the real SP1 verifying key. Do not read the running network as having real verification yet.
EVM has been merged to **master**, but is not live. Going live on A1 needs a re-genesis (it changes the coin-type, 118 → 60). So a master build (coin-type 60 + EVM) differs from the running testnet (coin-type 118); to match the live network, check out the tag **v0.2.1-testnet**.
The public repository is not yet published (the xchain org name is held by others), so the clone URL in Run a Node is a placeholder until then.

🔭 The vision — future tense. The path scales the hard walls one at a time:

Diagram

Figure 5 — The phased roadmap. "Aggregate toward 1B TPS" is aggregate nominal throughput (Execution ~100M + Data ~900M), not a billion composable transactions over one global state.

The testnet blueprint (design, not operational) is 3 Execution-Layer chains + 9 Data-Layer namespaces on one DA node — the minimum that proves the mechanism. Beyond the technical phases, the roadmap includes progressive decentralization: widening governance from the protocol (x/gov, already live) to the project's direction, strategy and this whitepaper — so the community, not a founding team, sets the course.

The last word: if you can verify it on the live network, it is real; if it is written in the future tense, it is the vision We are building toward — out in the open, one honest milestone at a time. Come check Our work, and come build.
