RGM Core v2.0.0 — Emergency difficulty fix + checkpoint

First post-launch update. After launch, a large miner spiked the difficulty and then left, and the network stalled at block 363 ("stuck at peak difficulty"). This release fixes the root cause.

What changed

  • Emergency difficulty rule: if no block is found for 3 hours, the next block is allowed at minimum difficulty, so a departing large miner can no longer freeze the chain. Activates at block 364.
  • Checkpoint at block 363, plus nMinimumChainWork and defaultAssumeValid.

This is a coordinated hardfork at block 364. Nothing was rolled back — every coin mined so far stays with its miner.

Network access right now (please read)

During this early phase, external peer connections (P2P) are intentionally limited: the network currently runs on the core nodes, and outside nodes will be opened up at block 25000. Until then:

  • Mining is available now via solo mining through the public endpoint.
  • The light wallet (RGMWallet) works now.
  • A full node or rgm-qt you run yourself will not sync to the network until external P2P is opened at block 25000. Updating now is fine and recommended, but external nodes connect from block 25000 on.

Who this update is for

  • Full node operators and rgm-qt users: update to this version so you are ready when external nodes are opened at block 25000. Required to follow the network past block 364.
  • Ordinary miners (RGMMiner.exe): no update needed — the solo miner does not embed consensus rules.
