[ANN] Quantum Bitcoin (QBTC) - New Pure CPU Mineable Coin (ML-DSA-65)

General
,
#1

Hi HiveOS Community! :wave:

We are the core team behind Quantum Bitcoin (QBTC), a newly launched, pure CPU-mineable cryptocurrency built on the quantum-resistant ML-DSA-65 algorithm.

We are currently in the early miner acquisition phase (pre-exchange), making this the perfect time for early adopters with idle CPU power to join our network. Our mainnet is extremely stable and has already passed block 20,000.

Coin Specifications:

  • Name: Quantum Bitcoin
  • Ticker: QBTC
  • Algorithm: ML-DSA-65 (Optimized for CPU)
  • Type: Pure PoW

How to start mining on HiveOS:
Since we are purely CPU-based, you can easily configure your Flight Sheet using a custom CPU miner setup pointing to our official stratum pool:

  • Stratum URL: stratum+tcp://144.172.110.193:3334
  • (Note: Ensure you generate a QBTC wallet address first to receive your block rewards.)

We have already submitted listing requests to MiningPoolStats and Minerstat. Join us early and let’s secure the quantum-resistant future together!

Feel free to ask any technical questions below. We are here to help!

[UPDATE: HiveOS Custom Miner Integration Bounty & Official Community]

Hello HiveOS miners! As the network has stabilized past Block 20,000, we are actively looking to streamline the deployment process for large-scale CPU farms.

We know that managing Ryzen/EPYC clusters requires smooth tools. Therefore, we have allocated a dedicated Genesis Bounty (paid in early QBTC) for any experienced developer or node operator who can build a seamless 1-click “Custom Miner” integration script/package specifically for HiveOS.

If you have the shell-scripting skills, want to secure an early stake in the network, and be recognized as a Core Contributor, come claim the task and discuss the architecture in our official Telegram group:

Let’s get this optimized for the major farms.

[UPDATE: Network Hard Fork Successful & v2.3.1 Node Upgrade]

Hello HiveOS miners! A quick status update as we have safely crossed block 21,900.

The network recently underwent a successful hard fork at block 21,500. The ML-DSA-65 signatures and the ASERT difficulty engine handled the transition perfectly.

:warning: CRITICAL FOR POOL & NODE OPERATORS:
If you are running your own local nodes or stratum proxies for your Ryzen/EPYC clusters, you must update your core node to v2.3.1 immediately.
Mining on the pre-fork code will result in orphaned blocks. Please ensure your infrastructure is fully synced with the new rules to make your hashes count.

Update your Core Nodes here: GitHub - Q-Jack-core/quantum-btc: A Post-Quantum Peer-to-Peer Electronic Cash System · GitHub

If you need any technical help migrating your farm to the v2.3.1 network, jump into our official Telegram:

Let’s keep building!

[UPDATE: Crossed Block 23,700 | Native Post-Quantum Architecture]

Hello HiveOS miners!

A quick update on network progress and the evolving macro landscape:

1. Network Milestone: 23,700+ Blocks

The Q-BTC mainnet has safely crossed Block 23,700. Distributed nodes across North America, Europe, and Asia remain fully synchronized, maintaining rock-solid consensus and healthy difficulty adjustment (DAA) dynamics.

2. Why “Native Post-Quantum” (ML-DSA-65) Matters Right Now

While industry leaders are suddenly sounding alarms about ECDSA vulnerability and urging users into “bunker mode” (avoiding address reuse, fearing public key exposure, and preparing for chaotic emergency migrations), Q-BTC was built from Day 1 to eliminate this fear entirely.

  • No Bunker Mode Required: Q-BTC uses native, standardized NIST FIPS 204 (ML-DSA-65) stateless signatures from the Genesis block.
  • Zero Exposure Anxiety: Public keys are cryptographically secure against quantum and AI-accelerated algebraic attacks. There is no need to hide behind disposable hashes or risk fund loss during hurried migrations.

3. Mining Recommendations: Connect to the Stratum Pool

With difficulty dynamically adapting as more nodes join the network, solo mining on consumer CPUs carries higher variance. For consistent block rewards, we strongly recommend pointing your HiveOS rigs to the official Stratum pool:

  • Stratum Endpoint: stratum+tcp://144.172.110.193:3334

  • Pool Dashboard & Live API: http://144.172.110.193:3335/api/stats

  • Wallet Setup: Ensure your Flight Sheet has your valid Q-BTC wallet address configured.

  • Mainnet GitHub (v2.5.0): github.com/Q-Jack-core/quantum-btc

[UPDATE: Network Milestone 24,000+ | Native GPU CUDA Support Released | 6+ GH/s]

Hello HiveOS miners and GPU farm operators!

We are excited to share a major architectural leap for the Quantum Bitcoin (QBTC) mainnet:

  1. Network Hashrate & Chain Health:
  • Network Hashrate: Crossed 6 GH/s (multi-fold growth transitioning from early CPU phases).
  • Blockchain Height: Passed Block 24,000+ with seamless difficulty adjustments (DAA).
  • Reference Stratum Pool: Fully operational at stratum+tcp://144.172.110.193:3334 (dynamic Vardiff enabled).
  1. Core v2.6.0 & Desktop v1.2.0 Officially Deployed:
  • Natural PoW Hardware Evolution: As the community began experimenting with specialized hardware, we integrated an official in-tree CUDA backend to prevent closed-source hash monopolies and defend a strictly fair, 0% dev fee playing field.
  • Native In-Tree CUDA Backend: High-performance GPU mining is now directly integrated into upstream core. No third-party closed-source binaries required.
  • Strict 0% Dev Fee: In true Cypherpunk fashion, upstream code contains zero developer tax and zero hidden fees. 100% of your hashing power works for you.
  • Smooth Fallback: Automatically falls back to multi-threaded CPU hashing if no CUDA device is detected, keeping CPU rigs fully viable.
  1. HiveOS Mining Setup:
    Point your custom GPU/CPU miner flight sheets directly to the reference pool:
  • Stratum: stratum+tcp://144.172.110.193:3334
  • Pool Stats API: 144.172.110.193:3335/api/stats
  • Upstream GitHub: github.com/Q-Jack-core/quantum-btc/releases/tag/v2.6.0
  • Desktop Releases: github.com/Q-Jack-core/qbtc-desktop/releases/tag/v1.2.0

Let’s test the numbers! If you are running RTX 30/40/50 series or CPU rigs on HiveOS, feel free to benchmark and drop your hashrate/power consumption below.

[UPDATE: Block 25,450+ | Core v2.6.2 & Desktop GUI v1.2.2]

Hi everyone, here is a quick update on the Q-BTC mainnet and our latest releases.

With Google recently publishing their 40x quantum error-reduction results on the Willow chip, and reports from Coinbase and Fidelity discussing the challenges of migrating 6.9M exposed BTC and handling large post-quantum signatures, here is a brief look at how Q-BTC handles these issues today:

  • Native ML-DSA-65 from Genesis: On legacy chains, broadcasting a transaction exposes the secp256k1 public key in the mempool while waiting for confirmation. Q-BTC uses NIST ML-DSA-65 natively from Genesis, so public keys in the mempool and on-chain are not vulnerable to Shor’s algorithm.
  • Built for Post-Quantum Signatures: Because Q-BTC started with post-quantum cryptography from day one, there are no legacy addresses to migrate. Larger ML-DSA signatures are handled directly at the protocol level through PQ-SegWit (up to 8 MB / 32M weight units) and compact block relay.

What’s New in Core v2.6.2 & GUI v1.2.2:

  • Mainnet has passed Block 25,450+ (including the smooth activation of the Block 25,000 witness commitment upgrade).
  • Added full CUDA build support for NVIDIA GPUs from GTX 10 series to RTX 50 series (0% dev fee, with automatic CPU fallback).
  • Minor sync fixes and updated GPU mining documentation.
