I'm excited to share ASTRA v1.0, a smart contract language with formal guarantees enforced through six "ASTRA Axioms":

1. Authority is explicit and monotonic 2. No execution without a selector 3. No state mutation without capability 4. No nondeterminism without entropy gate 5. No upgrade without governance authority 6. Replay must reproduce identical results

The Problem: Current smart contract languages make it difficult to prove determinism, enforce security properties, or deploy to multiple chains. Auditing is challenging because execution isn't perfectly reproducible.

The Solution: ASTRA enforces these axioms at runtime, guaranteeing: - Perfect determinism (every execution is replayable) - Explicit security (capability-based access control) - Multi-chain deployment (write once, deploy to TON and EVM) - Formal verification (complete Claude AI audit)

Quick Example:

    @selector
    @capability("StorageWrite")
    def increment():
        require_capability("StorageWrite")
        count = load_state("counter")
        store_state("counter", count + 1)
        return count + 1

The capability system is inspired by object-capability security, but adapted for blockchain state machines. Deterministic entropy uses hash-based PRNGs instead of block properties (no TIMESTAMP, NUMBER, etc.).

Try it: pip install astra-lang astra init my-contract

Would love feedback on: - The formal axiom approach - Multi-chain compilation strategy - Capability model design - Deterministic entropy implementation
