About the coin (primary summary)

  • What the coin is: Quantum Bitcoin (Q-BTC)
  • Mining algorithm: Not specified (the use of the ASERTi3-2d engine for difficulty adjustment is mentioned)
  • CPU‑only or not: Not specified (the announcement emphasizes protection against quantum attacks, but the type of mining algorithm is not named)
  • Brief description: The project positions itself as a “lifeboat” for Bitcoin in the era of quantum computing. The coin uses post‑quantum cryptography (ML‑DSA instead of ECDSA) and a Commit‑Reveal mechanism to protect the mempool from quantum front‑running.
  • Where to mine/pool: Not specified
  • Wallet/links: GitHub: https://github.com/Q-Jack-core/quantum-btc
  • Community reaction: Users discovered a critical vulnerability in the fund‑recovery function (possibility to steal coins), which the developers acknowledged and promised to fix in version v2.0.3.

Main topic of the new posts: Infrastructure update for Q‑BTC and addition of new features for users.

Key news/updates:

  • Deployed web explorer update (https://explorer.qbtc-core.org after reaching block #18,100
  • Added Web Wallet Interface feature — ability to generate an ML‑DSA‑65 wallet directly in the browser with secure encryption on the host node
  • Launched Faucet, distributing 5 QBTC to stimulate early network activity
  • Version v2.0.3 noted, where critical vulnerabilities in the fund‑recovery mechanism (risk of coin theft) will be fixed

Issues/complaints: None

Overall tone: Positive — the community is actively developing the project, introducing conveniences for miners and improving infrastructure.

Main topic of the new posts:

Quantum Bitcoin developers announced the release of new mining infrastructure (graphical client, reference stratum pool, and dedicated core repository) and shared an update on network stability after block 20 000, emphasizing the need for pool decentralization and performance optimization.

Key news/updates:

  • Code split into three separate repositories:
  • Q-BTC Desktop Miner – GUI client in Rust/Tauri with pre‑compiled binaries for macOS and Windows.
  • Q-BTC Stratum Pool – reference implementation of the stratum protocol for self‑hosting pools.
  • Q-BTC Core Node – main L1 node with ML‑DSA‑65 (repository quantum‑btc).
  • Official reference pool (port 3334) and auto‑payout daemon run stably; GUI client connects to it without issues.
  • Network stable after block 20 000.
  • Community is invited to create an open web dashboard for pools or launch competing pools to increase decentralization.
  • Request to optimize ML‑DSA‑65 for AVX‑512 (SIMD) to boost hashing speed.

Issues/complaints:

  • Lack of a commercial‑grade web interface for pools and need for a larger number of independent pools.
  • Current hashing implementation is limited in performance when vectorized with AVX‑512.

Overall tone:

Positive/motivating – developers are pleased with network stability and actively invite the community to further develop and improve the project.

Summary of new posts about Quantum Bitcoin (Q‑BTC)

Main topic of the new posts

The Quantum Bitcoin (Q‑BTC) team published an update on network progress beyond block 21 900. Along with this, warnings about orphan‑block issues were raised and a call to upgrade to version v2.3.1 to maintain synchronization.

Key news/updates

  • Network progress: The network successfully passed block 21 900 and operates stably
  • Post‑quantum security: Flawless operation of ML‑DSA‑65 signatures on the chain confirmed
  • Upgrade: Successful network upgrade at block 21 500
  • Desktop tools: qbtc-desktop released for easy node launch and mining on regular computers
  • GitHub repositories:
  • Core Node v2.3.1: https://github.com/Q-Jack-core/quantum-btc
  • Desktop GUI Miner: https://github.com/Q-Jack-core/qbtc-desktop

Issues/complaints

  • Orphan blocks: Users may see orphan blocks if they use an old code version (pre‑fork). It is recommended to upgrade to v2.3.1 to avoid this issue
  • Mining: Beginners are advised to use the provided desktop interface instead of specialized hardware

Overall tone

Positive — the team is highly communicative, supports the community, and offers convenient tools for users.

Main topic of the new posts:

Users share results of an independent field test of Q‑Bitcoin Core v2.5.0 (mining, node upgrade and recovery after synchronization issues) and discuss the web‑wallet operation, including a request for seed‑phrase recovery and the developers' response.

Key news/updates:

  • Web explorer updated: after a hard refresh (Ctrl+F5 / Cmd+Shift+R) at https://explorer.qbtc-core.org a “Web Wallet” tab → sub‑tab “Restore from Seed” is available, where you can enter a 12‑word seed phrase, set an alias and password to recover ML‑DSA‑65 keys.

Issues/complaints:

  • On the second machine persistent node synchronization problems occurred (it was necessary to isolate the old chain state and rebuild the database from scratch).
  • The user could not reopen the previously created web wallet – the interface only offered to create a new wallet.

Overall tone:

Overall positive/neutral: the tests show that core functions work, and the discovered issues are being addressed (web‑wallet update, successful node recovery).

Main topic of the new posts:

Announcement of the release of updated QBTC Core v2.6.0 and desktop miner v1.2.0 with GPU acceleration support via CUDA, as well as network hash rate growth above 6 GH/s and surpassing block height 24 000.

Key news/updates:

  • Network hash rate exceeded 6 GH/s, blockchain successfully passed block 24 000+ with smooth difficulty adjustment.
  • Release of QBTC Core v2.6.0 (source code and binaries) – https://github.com/Q-Jack-core/quantum-btc/releases/tag/v2.6.0
  • Release of QBTC Desktop GUI Miner v1.2.0 – download link (provided in the post).
  • Added official in‑tree CUDA backend for GPU mining, with 0 % dev fee and automatic fallback to multithreaded CPU mining when no CUDA device is present.

  • The base consensus layer based on ML‑DSA‑65 remains stable and reliable as it scales.

Issues/complaints:

  • No issues or complaints were mentioned in this post.

Overall tone:

Positive – emphasis on network growth, consensus stability, and the release of open updates without hidden fees.
