**Deterministic safe prime oracle and cryptographic primitive.**

EchoPrime provides a deterministic method for estimating, locating, and verifying safe primes using an analytic projection based on the Bateman-Horn heuristic. It includes a symbolic collapse score verifier and an oracle trace format for on-chain publication.

## Key Features

- **Analytic Estimator** — Projects the n-th safe prime location using `p_n ≈ a · n · (log n)²` with empirically fitted constant `a ≈ 2.8913`
- **Symbolic Collapse Verifier** — Verifies primes using binomial coefficient divisibility (Lucas' theorem)
- **Safe Prime Finder** — Deterministic search from estimated regions
- **Oracle Traces** — SHA-256 hashed records for on-chain publication
- **Ethereum Contract Format** — Ready-to-submit tuple format for smart contracts

## Installation

```bash
pip install echoprime
```

Or from source:

```bash
git clone https://github.com/DarrenEdwards111/echoprime.git
cd echoprime
pip install -e .
```

## Quick Start

```python
from echoprime import (
    estimate_nth_safe_prime,
    find_safe_prime_near,
    verify_safe_prime,
    create_trace,
)

# Estimate where the 100th safe prime lives
estimate = estimate_nth_safe_prime(100)
print(f"Estimate for index 100: {estimate}")

# Find the actual safe prime near that estimate
p, q = find_safe_prime_near(100)
print(f"Found safe prime p={p}, Sophie Germain q={q}")

# Verify with symbolic collapse scoring
result = verify_safe_prime(p)
print(f"Verified: {result['verified']}")
print(f"Collapse score (p): {result['score_p']}")
print(f"Collapse score (q): {result['score_q']}")

# Create oracle trace for on-chain publication
trace = create_trace(
    index=100, p=p, q=q,
    score_p=result['score_p'],
    score_q=result['score_q'],
    verified=result['verified'],
)
print(f"Trace hash: {trace['hash']}")
```

## The Math

### Safe Primes

A **safe prime** is a prime `p` such that `q = (p-1)/2` is also prime. The prime `q` is called a **Sophie Germain prime**.

### Analytic Projection

The n-th safe prime is estimated using:

```
p_n ≈ a · n · (ln n)²
```

where `a ≈ 2.8913` is an empirically fitted constant derived from the Bateman-Horn conjecture applied to the polynomial pair `(x, 2x+1)`.

### Symbolic Collapse Score

For a candidate prime `p`, the collapse score measures:

```
S(p) = |{k ∈ [1,T] : C(p,k) ≡ 0 (mod p)}| / T
```

By **Lucas' theorem**, for any prime `p > T`, all binomial coefficients `C(p,k)` for `1 ≤ k ≤ T` are divisible by `p`. Therefore `S(p) = 1.0` for all primes above the window size (default T=128).

## Smart Contracts

EchoPrime includes an Ethereum-compatible smart contract (`EchoPrimeOracle.sol`) that serves as a public, on-chain registry for verified safe primes.

### Features
- **Submit** — Publish a verified safe prime with its index, collapse scores, and primality verdict
- **Batch submit** — Submit up to 100 primes in a single transaction
- **Query** — Retrieve any published prime by its deterministic index
- **Access control** — Owner can authorize oracle bots as submitters
- **Events** — Every submission emits a `PrimeVerified` event for off-chain indexing

### Quick Start

```bash
cd contracts
npm install
npx hardhat compile
npx hardhat test          # 20 tests
npx hardhat run scripts/deploy.js --network sepolia
```
