About Qubitcoin (QTC)
Your guide to Qubitcoin (QTC), a proof of work coin built on Bitcoin Core whose hash runs a small simulated quantum circuit, mined on GPUs. Below: live network stats and market data, GPU benchmarks, the emission curve and how to start mining QTC with a pool.
Everything you need to mine and follow Qubitcoin (QTC) in one place. Qubitcoin keeps Bitcoin's 21 million coin cap and its halvings, and it is mined on GPUs with the qhash algorithm.
Qubitcoin (QTC) is a proof of work coin built on Bitcoin Core. It keeps Bitcoin's money rules: a cap of 21 million QTC, a 50 QTC block reward that halves every 210,000 blocks, and the same address formats, so an address starts with bc1, 1 or 3. What it changes is the work: every hash runs a small simulated quantum circuit, and blocks are found on graphics cards. Its genesis block is dated 28 October 2024.
How does Qubitcoin mining work?
Qubitcoin uses qhash. The miner hashes the block header with SHA-256, uses that result to set the angles of a simulated 16-qubit circuit, measures each qubit, and hashes the first result together with those measurements with SHA-256 again. The pool sends each miner a job, the miner searches for nonces on its GPU, and every result that meets its share difficulty is submitted as a share. The network targets one block every 10 minutes and adjusts its difficulty to hold that pace.
Why mine Qubitcoin?
Qubitcoin is mined on NVIDIA, AMD and Intel graphics cards with qhash. Its supply follows Bitcoin's schedule, and the block reward carries no developer fee: the whole reward and the transaction fees go to whoever finds the block.
Tokenomics and emission
The maximum supply is 21,000,000 QTC, the same as Bitcoin. Each block paid 50 QTC at launch, and the reward halves every 210,000 blocks, about every four years at the 10-minute target, so the first halving is at block 210,000. Miners also collect the transaction fees of every block they find, and newly mined coins can be spent after 100 confirmations.
Getting started with Qubitcoin
First you need a Qubitcoin wallet address. Qubitcoin uses Bitcoin's address formats, so it starts with bc1, 1 or 3. Next, download a miner that supports qhash, such as SRBMiner-Multi, WildRig NG or ForgeMiner, point it at your closest HeroMiners server with your address as the username, and start mining. Our How to Mine guide has ready-made command lines and per-region connection details.
Bitcoin's rules, a quantum-circuit hash
A quantum circuit in every hash
qhash simulates 16 qubits through two layers of rotations and a chain of CNOT gates, and the measured result goes into the final SHA-256 hash.
GPU Proof of Work
Blocks are found on NVIDIA, AMD and Intel graphics cards with miners such as SRBMiner-Multi and WildRig NG.
Built on Bitcoin Core
The node is a Bitcoin Core fork, so addresses and transactions work the way Bitcoin's do.
Bitcoin's supply schedule
21 million QTC in total, a 50 QTC starting reward and a halving every 210,000 blocks.

Qubitcoin emission curve
Total supply by block height, from zero toward the 21 million QTC cap. Each block paid 50 QTC at launch and the reward halves every 210,000 blocks, so each step adds half as much as the one before. 2,520,000 blocks is about 48 years at the 10-minute target.

Frequently asked questions
qhash hashes the block header with SHA-256, uses that result to set the angles of a simulated 16-qubit circuit, and hashes the first hash together with the circuit's measured output with SHA-256 again. The pool sends your miner a job, your GPU searches for nonces, and every result that meets your share difficulty is submitted as a share and checked before it counts. The network aims for a block every 10 minutes.
A recent NVIDIA, AMD or Intel graphics card. The GPU benchmarks on the About Qubitcoin page rank the cards measured on qhash by hashrate and by efficiency.
Qubitcoin uses Bitcoin's address formats: bech32 addresses starting with bc1q, Taproot addresses starting with bc1p, and legacy addresses starting with 1 or 3. The pool checks your address at login and tells you if it is not a valid Qubitcoin address.
It has the same format, so a Bitcoin address is also a valid Qubitcoin address. Only mine to an address whose wallet you control on the Qubitcoin network: QTC sent to an exchange's Bitcoin deposit address is not credited to you.
Each block pays a subsidy plus the transaction fees in that block. The subsidy started at 50 QTC and halves every 210,000 blocks, about every four years, toward a maximum supply of 21 million QTC, the same schedule as Bitcoin. There is no developer fee on the reward.
The same port, 1195, serves both. Use stratum+tcp:// for a plain connection or stratum+ssl:// for an encrypted one.
Yes, prefix your wallet address with "solo:" when connecting. In solo mode you receive the full block reward (minus the solo fee) for blocks you find yourself, but with much higher variance than pool mining.
