Neuron registration trends
Subnet 63 is a decentralized quantum computing network that incentivizes miners to efficiently solve quantum circuit challenges (Peaked Circuits and Hidden Stabilizer circuits) using classical simulation or quantum hardware. Validators generate quantum circuits with hidden bitstrings that miners must identify through quantum simulation, creating a verifiable quantum computing ecosystem that rewards both accuracy and the ability to handle increasingly larger circuits.
Subnet 63 operates as a quantum challenge-response system. Validators (whitelisted, high-resource nodes) generate quantum circuits with hidden bitstrings and distribute them to miners. Miners receive circuit challenges via axon synapse connections and solve them using quantum simulators or quantum hardware, returning the identified bitstring.
Validators verify correctness and score miners based on circuit complexity and qubit count. Miners prioritize requests from validators based on stake (priority is caller's stake weight). The metagraph synchronizes every 5 minutes on miners and continuously on validators.
Validators set weights on miners every 30 minutes based on performance. Certificate distribution enables miners to solve larger, longer-running circuits with hours-to-days runtime. The network supports two circuit types: ChallengePeakedCircuit (general quantum circuits) and ChallengeHStabCircuit (hidden stabilizer circuits with restricted operations).
Miners must first correctly identify the peaked state (hidden bitstring) to receive any score. The size function G is piecewise: for circuits ≤32 qubits, score increases linearly from 0.15 (12 qubits) to 0.40 (32 qubits); for circuits >32 qubits, score increases exponentially with base 1.7 from 0.40 to 1.00 (50 qubits). Entanglement entropy rewards circuits with more 'quantumness'.
Scores decay with half-life of 72 hours. Validator-miner collusion is strictly monitored and results in permanent removal from whitelist.

Holder & total-staked metrics as of 1h ago (hourly snapshot)
GPU recommended for better performance but not strictly required. Miners solving circuits beyond 32 qubits will need significant RAM or innovative memory-efficient approaches. Storage: minimum 16 GB free (SSD preferred with 1000+ IOPS), recommended 100 GB with 5000+ IOPS.
High-end GPU and strong CPU required for fast circuit generation to serve all miners. Storage: minimum 128 GB free (SSD preferred with 1000+ IOPS), recommended 256 GB with 5000+ IOPS. Validators are whitelisted; contact subnet maintainers to be added.
