Validiti Maths

Deterministic computation, signed receipts. Every calculation reproducible, every answer signed, every history queryable.

What you get

A sealed binary of math kernels that turns every calculation your business does into a signed receipt. Damages calculations, statistical analysis, engineering math, scientific computation, financial modeling, tomographic and density-matrix math where quantum-experiment reproducibility on the chain is non-negotiable. Same answers a calculator gives you — with a chain of custody that holds up to a regulator, an auditor, or a court.

01 · What you can do with it

Four outcomes Maths delivers from day one. Reads-and-writes over your math: ask more, store more, retrieve more quickly.

Ask more

Run a thousand variations of the same calculation, compare side-by-side, keep every version. The questions your spreadsheet was too slow to ask are now tractable.

Store more

Every calculation, every input, every answer kept forever. The signed receipt is the audit trail. No separate logbook to maintain.

Retrieve more quickly

Pull up the calculation you did six months ago. Re-run it with the same inputs and verify the result. Walk a regulator through the chain.

Sign every answer

Every result carries a cryptographic receipt. Reproducible on any machine; verifiable by any party; admissible by construction.

02 · What an answer looks like

The same math problem, two ways. Both give the same number. Only one of them gives the receipt.

Live representative outcome · same math, two systems
Present value of $10,000 in 5 years at 6% annual discount rate
A standard financial math problem. Every spreadsheet does it. The difference is in what you get back besides the answer.

No receipt. No chain. No way to reproduce six months later without re-typing the formula. If a regulator asks “how did you arrive at this number?”, the answer is “I typed it into a spreadsheet.”

Reproducible: any device running the same kernel · same inputs · same answer · same receipt
What the receipt buys you: a regulator can reproduce the calculation from the receipt alone. Six months later, six years later. No re-typing, no “trust me, this is what the spreadsheet said.” The math is the same; the chain of custody is what's different.

03 · What's in the sealed binary

Financial math kernels

Present value, future value, IRR, NPV, amortization, depreciation, tax-adjusted basis. All the calculations a small accounting practice runs every week.

Statistical kernels

Descriptive statistics, hypothesis tests, regression, time-series. The day-one needs of a forensic accountant, an actuary, or a clinic running outcomes studies.

Engineering math

Linear algebra, calculus, differential equations, FFT, optimization. Solid-state on commodity hardware; receipts for every solver run.

Damages + restitution math

Net-present-value of lost wages, discounted-cash-flow valuations, multi-year future-loss projections. Court-admissible by construction.

Scientific computation

Special functions, numerical integration, Monte Carlo, equation solving. For research labs that need reproducibility, not just speed.

The signed-chain layer

Every kernel call produces a signed receipt. Receipts compose into chains. Chains are queryable through Chronicle, Witness, and Aris.

04 · For your business

Three customer types where Maths replaces a stack you currently pay several thousand a year for.

Forensic accountant

Damages valuations a regulator can verify

Every loss calculation, every assumption, every discount rate signed and dated. A judge can re-run the math from the receipt without your spreadsheet.

Engineering firm

Calculations that survive the audit

Structural analyses, system sizing, tolerance stacks. Each calculation traces to the kernel and version that produced it. Liability cleaner.

Independent investor + advisor

Position sizing and scenario math, signed

Every return calculation, every risk metric, every present-value scenario carries its receipt. Six months from now, you remember why.

05 · Pricing · install

Marketplace fabric pricing
$99 · per year
Or included in All-Access at $499/yr covering every Validiti Marketplace SKU.
Install path: we supply hardware preconfigured, or we install on yours. Self-install is not offered — integrity is built in at install time.
Coming Soon at launch Notify-at-launch list active. No live downloads until the secure binary ships.

06 · Trust · what we will not do

01
Sealed binary, signed at every release

You install it; we maintain the chain of custody on the binary itself. No source readable.

02
Records-only output

Maths reports what the math says; it does not make a truth-claim about your subject. The interpretation is yours.

03
Hyperscaler exclusion

License terms exclude majority-owned subsidiaries of top-tier hyperscale cloud providers. Your math is not absorbed into someone else's cloud.

04
No business prescription

We provide the math kernel and the signed receipt. How you use it in your practice is your business, not ours.
