From 337c68013c71a3fd3fb2977853e7ad70b075d6c8 Mon Sep 17 00:00:00 2001 From: aitbc1 Date: Mon, 16 Mar 2026 09:24:07 +0000 Subject: [PATCH] feat(blockchain): production genesis with encrypted keystore, remove admin minting MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Introduce production setup script: scripts/setup_production.py - Generates aitbc1genesis (treasury) and aitbc1treasury (spending) wallets - Encrypts keys via AES-GCM, stores password in keystore/.password (600) - Creates allocations.json and genesis.json with fixed total supply - Sets mint_per_unit=0 (no inflation) - Update make_genesis.py: - Accept allocations file instead of single faucet - Use 'allocations' key in genesis (renamed from 'accounts') - Enforce mint_per_unit=0 in default params - Remove admin mint endpoint: - Deleting MintFaucetRequest and /rpc/admin/mintFaucet from router.py - Removes faucet CLI command from cli/aitbc_cli/commands/blockchain.py - RPC supply endpoint now computes total supply from genesis file (fixed) - Validators endpoint derives list from trusted_proposers config - Config enhancements (config.py): - Add keystore_path and keystore_password_file - Change mint_per_unit default to 0 - main.py: Auto-load proposer private key from keystore into settings.proposer_key (hex) for future use - Launcher scripts: - scripts/mainnet_up.sh: Loads .env.production, derives proposer_id from keystore if needed, starts node + RPC - scripts/devnet_up.sh: Updated to use new allocations-based genesis and proper proposer address - Documentation: - Rewrite blockchain-node/README.md for production model (no faucet, keystore management, multi-chain) - Update MEMORY.md with production blockchain section - Database: Multi-chain support already present via chain_id foreign keys. This change makes the blockchain production‑ready: immutable supply, secure key storage, and removal of dev‑only admin functions.
