Ledger Architecture Codebase

Ledger Architecture Codebase

Below is a partial representation of the TasQ Ledger core logic, focusing on task assignment, proof verification, and settlement modules. This code is a simplified, production-aligned snapshot, demonstrating the structure and protocols leveraged in our architecture.

# TasQ Ledger - Core Components
# Language: Python 3.11
# Dependencies: web3.py, pymerkle, py_ecc, asyncio, SQLAlchemy

from web3 import Web3
from pymerkle import MerkleTree
import asyncio
import hashlib

# Ethereum RPC for settlement
w3 = Web3(Web3.HTTPProvider("https://mainnet.infura.io/v3/YOUR_PROJECT_ID"))

# Merkle Tree for task proof validation
task_tree = MerkleTree(hash_type="sha256")

class TasQLedger:
    def __init__(self):
        self.pending_tasks = []
        self.compute_nodes = {}
        self.credits_db = {}

    def register_node(self, node_id, specs):
        self.compute_nodes[node_id] = specs

    def submit_task(self, task_id, payload):
        self.pending_tasks.append({"task_id": task_id, "payload": payload})
        task_tree.append_entry(hashlib.sha256(payload.encode()).hexdigest())

    async def assign_tasks(self):
        for task in self.pending_tasks:
            best_node = max(self.compute_nodes, key=lambda x: self.compute_nodes[x]['benchmark'])
            await self.send_to_node(best_node, task)

    async def send_to_node(self, node_id, task):
        # Async RPC to node
        print(f"Dispatching task {task['task_id']} to node {node_id}")

    def verify_proof(self, task_id, proof):
        return task_tree.verify_leaf_inclusion(proof)

    def settle_payout(self, contributor_wallet, amount_eth):
        tx = {
            'to': contributor_wallet,
            'value': w3.toWei(amount_eth, 'ether'),
            'gas': 21000,
            'gasPrice': w3.toWei('30', 'gwei'),
            'nonce': w3.eth.get_transaction_count("YOUR_WALLET")
        }
        signed_tx = w3.eth.account.sign_transaction(tx, "PRIVATE_KEY")
        tx_hash = w3.eth.send_raw_transaction(signed_tx.rawTransaction)
        return w3.toHex(tx_hash)

# Example usage
ledger = TasQLedger()
ledger.register_node("node123", {"benchmark": 9500, "cpu": "64-core", "ram": "512GB"})
ledger.submit_task("task001", "matrix-multiplication-job")
asyncio.run(ledger.assign_tasks())

Technical Highlights

• Merkle Proof Validation ensures integrity of all task data.

• Ethereum Settlement Module processes payouts in ETH via mainnet.

• Adaptive Task Assignment selects nodes dynamically based on live benchmarks.

• Async Node Communication supports parallel execution at scale.

This is a minimal working excerpt; the full codebase includes ZK proof generation (Halo2), task retry logic, and fault tolerance mechanisms.
