We are excited to introduce Superdense Consensus (SDC) - a new and unique multi-task Proof-of-Work architecture. Qubitcoin can now run multiple independent PoW challenges simultaneously on the same chain, each with its own difficulty adjustment and activation schedule. The first public code release is now available on the sdc-testing branch: 🔗 github.com/super-quantum/qub… We invite developers, researchers, and miners to explore the implementation, run tests, experiment with new workloads, and share feedback. Additional technical details are included in the updated README. Important notes: – This is an early-stage release; expect rough edges – Unit/integration tests and additional features are actively in development – Do not use the binaries compiled from the new branch in the production environments (critical bugs may be present)

🎉 Happy 1st Birthday, Qubitcoin! One year ago, we turned GPUs into quantum simulators and launched the world’s first quantum-inspired Proof of Work network. For our anniversary we prepared 10 fascinating facts about our journey over this incredible first year: 1️⃣ The Launch Date Mystery We launched on October 29, 2024 - exactly one year ago today! But here's a fun secret: we originally planned to launch on Halloween for the spooky vibes, but decided to go a day early when our tests were fully completed at 11:47 PM on the 28th. We took it as a sign from the quantum universe. 2️⃣ From 700 to 3,000 GPUs In just one year, we've grown from a handful of early miners to over 700 participants running 3,000+ GPUs making us the world's largest decentralized quantum computing network. That's more distributed quantum simulation power than most university research labs! 3️⃣ The "Bitcoin Blueprint" Legacy Qubitcoin is built on a Bitcoin Core fork, but with quantum superpowers. We kept the 21 million token supply cap as a tribute to Satoshi, but instead of wasting energy on useless hash puzzles, every single mining operation preforms quantum simulation. 4️⃣ The Night We Almost Broke Physics During early testing in September 2024, one of our developers ran a simulation that produced results that seemed to violate known quantum mechanics. We spent 72 sleepless hours convinced we'd discovered something groundbreaking... until we found a sign error in the rotation gate implementation. The bug is now immortalized as "The Minus Sign Incident" in our dev chat history. 5️⃣ NVIDIA's cuQuantum is Our Secret Weapon We leverage NVIDIA's cuQuantum SDK (specifically cuStateVec) to run our default GPU simulations. A 16-qubit circuit simulation takes just ~1 millisecond on a typical RTX 5060. That means we're processing quantum circuits faster than you can blink - literally! 6️⃣ The "Bring Your Own Solver" Revolution Unlike traditional mining where everyone runs identical code, our BYOS (Bring Your Own Solver) architecture means miners can plug in their own custom quantum simulators, CPU-based, GPU-optimized, tensor networks, or even actual quantum hardware. We've had miners experiment with everything from Raspberry Pi clusters to modified atom trap systems. 7️⃣ The Accidental Academic Citation Three months after launch, a quantum computing researcher from ETH Zurich accidentally cited data from our network in a preprint paper about variational quantum algorithms. They thought our public simulation results were from a university cluster! When they discovered it was from a cryptocurrency network, they were so impressed they joined as a validator and now contributes quantum circuit benchmarks. 8️⃣ The 24-Qubit Challenge Bounty In March 2025, we launched a bounty challenge: successfully simulate a specific 24-qubit circuit faster than our implementation and win QTC. A team from South Korea won using a custom algorithm that was 3.7x faster. Plot twist: they were high school students working on a science fair project. We hired one of them as a part-time contributor after graduation, and their algorithm is now under our continued research. 9️⃣ Our Not-So-Secret Motto Our GitHub readme cheekily ends with "It has not escaped our notice that the system we introduced suggests possible new findings in the realm of physics simulations" - a direct homage to Watson and Crick's famous DNA paper understatement. We like to think we're being similarly humble about potentially revolutionizing how humanity develops quantum algorithms. 🔟 The Texas Connection Superquantum, the organization maintaining the protocol, is based in Texas which gives us the unique distinction of being the only quantum computing cryptocurrency project where you can legitimately say "Everything's bigger in Texas, including our quantum circuits." We’ll be celebrating our 1st anniversary at @MIT on November 14, together with researchers, developers, and early contributors who helped bring quantum-inspired Proof of Work to life. During the event, we’ll also host the qPoW demo. Thank you to every miner, validator, developer, and supporter who's helped us prove that cryptocurrency mining doesn't have to be purposeless computation - it can literally advance human understanding of quantum, and we are here to make it a reality. May the qubits be with you! Here's to Year Two! 🥂 — The Superquantum Team

Behind the scenes… 👀 Fun day in the studio with @MYShalaginov Great vibes and plenty to talk about - from how the Qubitcoin story began at @MIT, to where this journey is heading and what comes next.
