Semantic Pattern Address — reference implementation of the MORPH semantic canonicalization standard

SEMPA — Semantic Pattern Address

SEMPA is the reference implementation of the MORPH semantic canonicalization standard.

MORPH is the standard. SEMPA is the implementation.

What is MORPH?

MORPH (Multidimensional Executable Patterns) is a semantic canonicalization standard that computes a language-independent PatternAddress for any function or program — based on its semantic structure, not its syntax.

Two functions that do the same thing, written differently or in different languages, get the same PatternAddress.

Python function
    ↓
SEMPA extractor
    ↓
PatternAddress: 0xa727d60b670188b9...
    ↓
Veralog attestation (Ed25519 signed, publicly verifiable)

Key Concepts

• PatternAddress — SHA3-256 of the canonical semantic representation. Language-independent.
• SourceHash — SHA-256 of the exact source text. Language-specific.
• PatternFamily — semantic category: Decision, PureFunction, StateMachine, Loop, etc.

Status

Currently in early development (Alpha). Full SDK coming in 0.2.0.

Live demo: app.vrlg.tech/morph-demo

Quick Start

pip install sempa

import sempa
print(sempa.version())  # 0.1.0

Full API (coming in 0.2.0):

from sempa import analyze, attest

result = analyze("""
def approve_loan(credit_score: int, amount: float):
    if credit_score >= 700 and amount > 0:
        return "Approved"
    return "Rejected"
""")

print(result.pattern_address)   # 0x40f5d23e...
print(result.pattern_family)    # Decision
print(result.source_hash)       # 0x65593b32...

# Attest to Veralog (cryptographic proof)
proof = attest(result, api_key="vrlg_...")
print(proof.verify_url)         # https://vrlg.tech/verify/.../page
