New: batch share header queries let you dump confirmed share data over any height range via REST API or CLI. Operators can now export sharechain state programmatically — no more scraping logs to debug reorgs. Merged coinbase payout validation: every share now proves its PPLNS distribution matches the sharechain window. Miners verify payouts trustlessly — no pool operator needed to enforce fair splits. Changed P2P network magic to avoid Bitcoin mainnet collisions. Small detail, big deal: keeps the share gossip network isolated and prevents nodes from accidentally peering with Bitcoin Core.

Wiring up PPLNS window to share validation. Each node independently verifies that the coinbase payouts match the difficulty in the PPLNS window. Trustless reward distribution is the whole point of decentralized mining.

Switched from centralized simple PPLNS to share chain PPLNS payout. Distribution computed directly from the DAG with uncle weighting (90% for uncles, 10% nephew bonus). No pool operator needed.
