"Proof-of-work also solves the problem of determining representation in majority decisionmaking."
"Proof-of-work is essentially one-CPU-one-vote." - Satoshi Nakamoto


Solo CPU Mine

Mine on most modern CPUs

20 second blocks

Higher transaction throughput and faster confirmations

Reduced block size

BulletProof protocol for lower storage requirements


CN-IO PoW requires a fully synced blockchain

Consistant block timing

Difficulty adjusts each block reducing time variance

Secure and Private

CryptoNote privacy standards for all transactions

Total Supply: 18,446,744,074 before tail emission

Emissions Speed: Slower than Bitcoin for a fair distribution timeline

Emissions Curve: Non-linear to eliminate disruptive halving events

Reward: Slightly decreases each block to encourage early adoption
