FAQ & glossary

Is XChain "a faster blockchain"? No. It's a two-base foundation layer for thousands of apps and chains to build on. It separates data by value instead of racing one chain's speed.

Is the "1 billion TPS" real? It's aggregate nominal throughput, mostly low-value data on a light, prunable tier — not a billion composable transactions over one global state. Today that's the vision; what's live is the 3+9 testnet.

Do you use ZK proofs (SP1) yet? The aggregation is real; the cryptographic prover is currently MOCK — a Groth16 stand-in. ProofSystem.MOCK is rejected off-testnet. A real SP1 prover is open work.

Can I buy the X token / invest? No. These are testnet coins with no value. There is no token sale, no mainnet, and no investment on offer. If XChain speaks to you, the way in is to use it, build on it, or help build it — and to watch it prove itself on www.xscan.org.

Why build on Cosmos instead of a brand-new consensus? Because of the principle: don't reinvent. Use proven parts (Cosmos SDK, CometBFT, IBC, Celestia, pessimistic proof) and create value in the integration, base-splitting and tiering.

How do I know XChain is telling the truth? Check it. The explorer shows real height, validators and transactions. The code is open (Apache-2.0). And this documentation separates here now from the vision on the Real Status page — so you never have to take our word for it.

GlossaryBase A / Secured Execution: consensus chains (T0–T2). Base B / Verifiable Data Fabric: the non-consensus namespace/log layer on DA (T3–T4). DA / DAS: Data Availability / Data Availability Sampling. PoP: Proof-of-Publication (published + timestamp + inclusion). PSS: Partial Set Security. ICQ / ICA: Interchain Queries / Interchain Accounts. XMP: XChain Messaging Protocol. Pessimistic proof: guarantees a chain can't withdraw more than it deposited (containment). Security-class: the minimum security tier bound to each asset (SOVEREIGN / SHARED / ZK_SECURED). MVC: Minimum Viable Core. VLC: Verifiable Log Commitment. STC: State Transition Certificate.

The last word: if you can verify it on www.xscan.org, it's real. If it's written here in the future tense, it's the vision we're building toward — out in the open, one honest milestone at a time. Come check our work.
