Run your own node
Needs Python 3.8+ only (no extra libraries).
python3 eddycoin_node.py
python3 eddycoin_node.py --headless --seed https://129-159-188-73.sslip.io
# let others connect:
python3 eddycoin_node.py --headless --listen 0.0.0.0 --port 8770 \
--public-url https://your.host.example
Then point your miner or wallet at http://127.0.0.1:8770. More options: --peer URL, --data DIR, --behind-proxy, --follow-only.

Consensus parameters
- Two PoW chains, both sha256d: E-Chain (CPU) and D-Chain (GPU). A block is valid when its hash has at least
bitsleading zero bits (≈ 2^bits hashes per block). - Y-Chain checkpoints: each needs one E and one D block for the same Y candidate; it carries the transactions and the reward.
- Target block time 30 s; difficulty retargets every 10 blocks from arrival times (max step 2 bits); range E 18–34, D 20–40 bits; genesis E 28 / D 33.
- Reward per checkpoint 149.85005307 EDDY, 50 % to the E block finder / 50 % to the D block finder (+ fees); × 0.998335 every 10,000 checkpoints.
- Max supply 900,000,000 EDDY, 8 decimals. No premine, no faucet.
- Transactions: UTXO, ECDSA P-256 signatures, min fee 0.01 EDDY, max 40 tx per checkpoint. Address =
eddy1+ 40 hex characters. - From checkpoint 300: block time within ±30 s of arrival and after the median of the last 11 blocks.
