SCDO shard0 GPU miner for Windows (NVIDIA)          https://scdoscan.io/downloads/shard0/
=====================================================================================

What it does (all on this PC):
  bin\geth.exe          core-geth v1.12.23 node for SCDO shard0 (chainId/networkId 5680), syncs from
                        the public bootnode 82.223.19.88:30368. Its --miner.etherbase = YOUR wallet,
                        so block rewards (2 SCDO + fees per block) go to your address.
  bin\scdo-stratum.exe  small stratum -> getwork proxy on 127.0.0.1:3333 (ethproxy and
                        EthereumStratum/1.0.0). It starts mining only after the node has synced
                        and pauses if the node loses all peers.
  Rigel 1.23.2          NVIDIA miner (RTX 20/30/40/50 series incl. RTX 4060 and RTX 5060 Ti).
                        Downloaded on first start from the official GitHub release
                        https://github.com/rigelminer/rigel/releases/tag/1.23.2 and checked
                        against SHA256 0a35d37504e2595f2cd9bb25ae69eae39625be6f0ebbdbaf7427d4c381a7fd79.
                        Rigel is closed source and takes a 0.7% dev fee on ethash.

Steps
  1. Unzip to a short folder without spaces/Chinese characters, e.g. C:\scdo-miner
  2. Windows Security > Virus & threat protection > Manage settings > Exclusions >
     Add an exclusion > Folder > C:\scdo-miner   (Defender flags every GPU miner as a
     "potentially unwanted app"; without the exclusion rigel.exe gets deleted).
  3. Right-click start-mining.bat > Edit, set your address on the line
         set WALLET=0x...
     (a MetaMask/EVM address you control; 0x + 40 hex digits). Save.
  4. Double-click start-mining.bat. First start: downloads Rigel (~56 MB), creates the
     chain database, starts two small windows "SCDO node" and "SCDO proxy" and waits
     until the node is synced (1-5 minutes). If Windows Firewall asks about geth.exe,
     click Allow (private networks).
  5. Rigel shows the hashrate and "accepted" shares. Blocks you find show up at
     https://scdoscan.io/#/address?address=<your address>.
  To stop: double-click stop-mining.bat (stops Rigel/lolMiner, proxy and node of THIS folder),
  or close the Rigel window, then the "SCDO proxy" and "SCDO node" windows.
  Logs: logs\rigel.log (hashrate, accepted shares), logs\proxy.log (shares, "BLOCK FOUND"),
  logs\geth.log (node). shard0 difficulty is low, so one GPU finds a block almost every
  second at first; the proxy submits at most one block per second (block timestamps must not
  run ahead of the clock, otherwise other nodes reject them) and counts the rest as shares.

Second PC (e.g. RTX 5060 Ti): copy the same folder and do the same steps (it runs its
own node; the chain is small). Alternative: on PC 1 set LISTEN=0.0.0.0:3333, on PC 2 set
POOL=<PC1-LAN-IP>:3333 - then PC 2 only runs Rigel and rewards go to PC 1's wallet.

Other miners: the proxy accepts any ethash stratum miner, e.g.
  lolMiner.exe --algo ETHASH --pool 127.0.0.1:3333 --user 0xYOURWALLET --ethstratum ETHPROXY
Algorithm is plain Ethash (30000-block epochs, NOT etchash); epoch 0 DAG is about 1 GB.

Files: data\ = chain database (+ ~2 GB ethash DAG files after the first found block),
logs\rigel.log = miner log. Nothing here holds private keys: only your public address
is used. Mining this test chain has no guaranteed value.
