NVNM Chain Launches Layer 1 Testnet for Verifiable AI Data

NEW YORK, Oct. 15, 2026 /CourierPR/ -- NVNM Chain has launched its Layer 1 testnet, opening a platform for institutions and developers to build and test applications that anchor cryptographic proofs of data used in complex financial and AI workflows. This move addresses a key barrier to enterprise AI adoption by embedding attestation directly into the blockchain.
The new testnet allows for the creation of a single, chain-enforced standard format for records, ensuring that data from autonomous agents and developers conforms to this format. Each agent is assigned a persistent wallet identity, and role controls are built in. Proprietary source files remain secure and off-chain, with only cryptographic fingerprints committed to the blockchain. This setup enables counterparties and regulators to independently verify the provenance, state, and decision integrity of data on a public ledger, with fees paid in stablecoins and priced in dollars.
Bill Papp, CEO of NVNM Chain, emphasized the importance of auditability in AI-driven decision-making.
The testnet showcases immediate utility across several core institutional use cases. For instance, NVNM Cite, a legal citation verification tool, allows law firms to confirm that every cited case is a real, canonical citation and receive a tamper-proof on-chain receipt showing the check was run on a specific document at a specific time. Source briefs never leave the firm.
Measurabl, a provider of real estate and sustainability data verification, demonstrates how asset-level operational and ESG metrics can be cryptographically anchored to establish audited data integrity for sustainable finance and portfolio reporting. This ensures that data used in financial and environmental assessments is accurate and verifiable.
NVNM Trace, a tool for AI compute compliance, enables operators of advanced AI chips to anchor tamper-proof receipts that custody moved as declared, jurisdiction by jurisdiction. Exporters and regulators can verify the record of provenance of AI chips and processes without seeing proprietary workloads.
Maureen Waters, CEO of Measurabl, highlighted the importance of this technology in the real estate sector.
The architecture of NVNM Chain is designed to be sovereign, with a purpose-built blockchain that records cryptographic proofs of agentic activity. The architecture pairs Reth execution with Commonware Simplex BFT consensus and removes the volatile native gas token entirely. Transaction fees are paid in USD stablecoins, using any qualifying stablecoin accepted through the chain's built-in fee market. Developers can connect a standard EVM wallet, request testnet nUSD from the faucet, and deploy contracts against the native attestation precompile at docs.nvnmchain.io. Each attestation records three proofs: Proof of Origin, Proof of Process, and Proof of State.
NVNM Chain is a sovereign Layer 1 blockchain engineered for verifiable private market data and institutional AI workflows. By anchoring cryptographic proofs of inputs, actions, and algorithmic outputs directly on-chain, NVNM Chain enables independent counterparty verification while keeping underlying data sovereign, private, and secure.
