Built on Trust & Verified Fairness

From RBI-regulated escrow to cryptographic ledgering, NumTrade is engineered to be verifiable, tamper-proof and compliant by design.

How NumTrade Makes It Fair — Even If You’re Not a Mathematician

NumTrade isn’t a guessing game. Unlike lotteries or casino-style randomness, our system encourages smart choices and discourages copying others.

You pick a number. So does everyone else. But here’s the twist: the number with the least total money bet on it wins. Follow the crowd and you’re less likely to win.

The earlier — and more confidently — you place your bet, the larger your share of the reward pool. Fair, provable, and powered by smart math.

More Than a Game: A Research-Driven System

NumTrade applies behavioural game theory, decision-making under uncertainty and predictive allocation mechanisms.

Our round logic draws from:

Keynesian beauty-contest theory — participants try to out-guess one another.
Mechanism design — rules incentivise strategy over luck.
Dynamic weighting — logistic decay & power-law scaling reward early, confident bets.
Cryptographic data structures — Merkle trees secure round integrity.

A synthesis of applied mathematics, behavioural economics and provable fairness.

By blending real-world finance, academic modelling and open auditability, NumTrade sets new standards for compliant digital competitions in India.

Merkle Tree Transparency

After every round we compute a Merkle tree of all participant transactions. The root is sealed into our public ledger, ensuring tamper-evident integrity.

MERKLE_ROOT = MerkleTree([
  sha256(tx_1),
  sha256(tx_2),
  ...
]).root

Anyone can verify inclusion using a Merkle proof.

Avoiding the Crowd

Inspired by a Keynesian beauty contest, the winner is the digit receiving the least total wagers.

\[ n^* = \arg\min_{n \in \{0,1,\dots,9\}} \sum_{i \in B_n} A_i \]

Audited Payouts

Pool splits use stake size & bet timing. Logistic decay blocks last-second sniping.

\[ C_i = A_i^{\gamma}\!\left(\frac{1}{1+e^{\alpha(t_i/T-0.5)}}\right),\; P_i = \frac{C_i}{\sum_{j\in W}C_j}\,\text{Pool} \]

RBI-Compliant Escrow

All INR balances reside in an escrow account with a licensed payment aggregator — ring-fenced from NumTrade’s operational funds.
