CAC3 Launch Plan — Pending

What needs to happen before the first block

1. Bring over the Bitcoin Core 0.18 source tree from SamiAhmed7777/nyc3 (or the barrystyle/nyc3 upstream it was forked from).
2. Rename pass on every string literal:
   • nyc3 → cac3
   • NYC3 → CAC3
   • NewYorkCoin → Californiacoin
   • port 55555 → 55556
   • magic bytes 1f be ef f1 → fresh values
   • P2PKH base58 prefix 0x35 → 0x1e (Bitcoin's 'C' letter)
   • bech32 HRP ny → cac
3. Mine a fresh genesis block (find new nonce, recompute merkle root).
4. Replace genesis constants in src/chainparams.cpp and src/chainparamsbase.cpp.
5. Replace seed nodes with CAC3-run infrastructure.
6. Build cac3d + cac3-cli. Drop Qt wallet unless a maintainer volunteers for the GUI.
7. Run 3+ full nodes on hard, geographic diversity.
8. Mine the first 150 blocks (no difficulty adjustment until height 151).
9. Open the network — clients can connect.

What is NOT changing

• Argon2s PoW parameters — preserved exactly
• LWMA-3 difficulty algorithm — preserved exactly
• 10-second block target — preserved exactly
• Total supply schedule — preserved exactly
• Address format (bech32 + base58 P2PKH + P2SH) — preserved exactly

What this repo intentionally does NOT carry

The trust history of any prior chain. CAC3 starts at height 0 with fresh state. There is no on-chain bridge from any prior identity.
