1. Open-source licenses
TensorCash is published across several repositories under more than
one license. The authoritative, per-component map is
LICENSING.md
in the umbrella repository (with the accompanying
NOTICE);
the summary below mirrors it.
First-party code is released under the
Apache License 2.0.
This covers the umbrella repository's own code — including the
proof-of-inference verifier
(services/verification-api/) and the first-party shared
utilities, scripts, deployment manifests, and documentation.
Apache-2.0 is used deliberately for its explicit patent grant and
patent-retaliation clause which, together with dated public
disclosure, support a defensive posture around the project's novel
verification methods. This is defensive publication plus a contributor
patent grant — not a patent shield — and is not legal advice.
The Bitcoin-Core-derived consensus node — the core node, wallet,
consensus rules, and native settlement contracts (bcore)
— is under the
MIT License,
consistent with its upstream lineage. Bundled third-party components
remain under the licenses set by their upstream authors:
- Apache 2.0 — first-party umbrella code and the proof verifier; the vLLM forks; the vLLM production-stack fork; chiavdf.
- MIT — bcore (core node, consensus, settlement contracts); the llama.cpp fork; secp256k1-zkp; liboqs.
Each repository carries its own LICENSE/COPYING
and, where applicable, a NOTICE file; derivative
components retain their upstream copyright notices and attributions
(Bitcoin Core, vLLM, the llama.cpp / ggml authors, and others). Under
both MIT and Apache-2.0 the software is provided "as is", without
warranty of any kind, express or implied, including but not limited to
merchantability, fitness for a particular purpose, and
non-infringement; in no event are the authors or copyright holders
liable for any claim, damages, or other liability arising from the
software.
Documentation, whitepapers, and the contents of this website are
published under CC BY 4.0 unless explicitly marked otherwise.
2. Trademark
"TensorCash" is a name used by the project to identify the protocol,
its reference implementation, and adjacent research. These
licenses cover the code and documentation but do not grant
rights to use the project's name, logo, or marks in a way that
implies endorsement of, affiliation with, or origin from the project
team. Use of the TensorCash name in product names, exchange
listings, paid advertising, or public statements that suggest an
official relationship requires prior written consent.
Forks, research papers, and independent client implementations
remain free to identify themselves as TensorCash-compatible.
3. Software disclaimer
TensorCash is research software. The protocol, its economic
parameters, and its consensus rules are subject to change. Running
the software on mainnet or any value-bearing network is at the
operator's own risk. Nothing on this website, in the whitepapers,
or in the source code constitutes investment, legal, or tax advice.
The project has not conducted, and does not intend to conduct,
a token sale, ICO, IDO, or any equivalent fundraising event. Any
third party offering tokens, pre-sales, or "official" investment
opportunities under the TensorCash name is acting without authority.
Operators of nodes, validators, and mining hardware are responsible
for compliance with the laws of their own jurisdiction, including
those concerning energy use, computing-equipment imports, telecom
and broadcasting rules, KYC/AML obligations where the operator
provides regulated services, and tax treatment of any rewards.
