QuantaChain Testnet — V2 Alpha (v2.0.0)

Post-quantum secure blockchain using Falcon-512 signatures and Asynchronous Byzantine Fault Tolerance (AlephBFT).

v2.0.0 — TESTNET RESET (2026-06-06)
All nodes must wipe their databases (rm -rf ./quanta_testnet_data) and sync from the new genesis block.
New genesis hash: ae37fe2f40a7e7dbe6d2d1337f260d57185ef5fb169008e2600f245809fd1fbf

This is a pre-release testnet build. Do not use real funds. APIs and chain parameters may change between alpha releases.

What Changed in v2.0.0

  • Block timing fixed — Blocks were slowing from 6 s to 1–2 h due to a timestamp drift bug in create_block_template. Block timestamps now can never exceed wall-clock time.
  • Validator 5 replaced — Lost wallet 0x822dd149... replaced with 0x591277eb458e3185bef4fcf18c1c7136fb8bbad6.
  • Faucet wallets rotated — All 10 genesis faucet wallets replaced with new HD wallet accounts.
  • Genesis reset — Timestamp bumped to 2026-06-06, generating a new genesis hash that forces a clean chain wipe.

🚨 V2 Hard Fork Details 🚨

  • Consensus Engine: Migrated from SHA3-256 Proof of Work to AlephBFT (Asynchronous Byzantine Fault Tolerance).
  • Network Isolation: Updated network magic bytes to Q2T4 to prevent old nodes from connecting to the new consensus network.
  • Block Time: Exact 6-second deterministic slots (previously ~30s random).
  • Mining Removed: All start_mining commands and the quanta-miner binary have been removed.
  • AI Agent Support: Added headless QUANTA_WALLET_PASSWORD environment variable support for automated AI escrow workflows.
  • HD Wallets: The CLI wallet has been completely rewritten to support deterministic hierarchical generation natively.
  • Persistent Crash Recovery: AlephBFT DAG state is now persisted to disk (alephbft_backup.dat), allowing seamless recovery and network rejoin after node restarts.

🔄 Clean Start Guide (Wipe Data & Resync from Genesis)

You MUST perform a clean start to join the V2 Testnet!
The V2 BFT consensus engine uses a different block structure and state machine. It will crash if it reads old V1 PoW blocks.

Bare Metal / VPS (no Docker)

pkill -f "quanta start"    # stop the old node
rm -rf ./quanta_testnet_data  # WIPE THE OLD POW CHAIN DATA!
cargo build --release      # compile the new V2 binary
./target/release/quanta start -c quanta.toml

Validator Setup (Docker)

⚠️ ATTENTION: This is currently a strictly permissioned testnet designed only for testing. Only the validators explicitly hardcoded in the Genesis set can run a node and produce blocks.
Once the network matures, we will implement full DPoS, allowing anyone to stake and participate in consensus. Until then, if you would like early access to participate, please email: contact@quantachain.org

If you have been selected as a validator, follow these exact instructions to spin up your validator node and connect to the core network using Docker:

1. Create a Wallet and Get Your Key
You must generate a raw wallet and provide the public key to the core team to be whitelisted in the Genesis block.

docker run --rm -it xd637/quanta-node:latest quanta-wallet new-raw --file /tmp/validator.qua

2. Directory Setup
Create the directory where your blockchain data will live. We recommend adding _v2 to avoid mixing it with any old testnet data:

mkdir -p ~/quanta_data_v2

3. Place Your Wallet File
Move your validator wallet file (e.g., validator.qua or whatever you named it) directly into the ~/quanta_data_v2 directory you just created.

Your folder should look exactly like this:

~/quanta_data_v2/
└── validator.qua

(Note: You do NOT need the genesis.json or quanta.toml files! The latest network configuration is securely baked directly into the V2 Docker image.)

4. Pull the Latest Image & Start the Node
Run the following Docker commands to pull the latest V2 build, launch your node, connect to the Bootstrap node, and begin proposing blocks.

Important

Before running the second command below, you MUST change two things:

  1. Change "YOUR_PASSWORD_HERE" to your actual wallet password.
  2. Change validator.qua at the very end of the command to match the exact name of your wallet file.
docker pull xd637/quanta-node:latest

docker run -d \
  --name quanta-validator \
  --restart always \
  --network host \
  -v ~/quanta_data_v2:/home/quanta/quanta_data \
  -e QUANTA_WALLET_PASSWORD="YOUR_PASSWORD_HERE" \
  xd637/quanta-node:latest \
  quanta start --validator-wallet /home/quanta/quanta_data/validator.qua --bootstrap 79.137.78.1:8333

Wallet Management

# New HD Wallet (Recommended)
quanta-wallet new --file my_wallet.json

# New Raw Wallet
quanta-wallet new-raw --file my_raw.qua

# AI Headless Mode (Set env var to skip password prompts)
export QUANTA_WALLET_PASSWORD="your_password"
quanta-wallet info --file my_wallet.json
