Kvanta5 KV5

Kvanta5 (KV5) is an independent Proof-of-Work Layer 1 blockchain launched on 1 June 2026 with post-quantum transaction security built into the network from genesis.

The network uses SHA-256d mining and targets approximately 60-second blocks. Transaction ownership is handled through Kvanta5's native P2QR system, which uses ML-DSA-87 signatures standardized under NIST FIPS 204 at Security Level 5.

Unlike systems that plan to add post-quantum signatures later, Kvanta5 requires its post-quantum signing model at the protocol level. Native P2QR addresses use the kvqr1 format, while wrapped compatibility addresses are also available for infrastructure such as mining pools and exchanges.

KV5 has a protocol-level maximum supply of 231 million coins. The published supply model allocates 210 million KV5 to Proof-of-Work mining and 21 million KV5 to a consensus-controlled, time-locked development fund.

Kvanta5 targets settlement-oriented use cases and supports blocks of up to 32 MB, with a custom fragmentation and propagation system designed for the larger transaction sizes created by ML-DSA-87 signatures.

The project maintains an open reference node implementation, desktop wallet software, mining infrastructure, public explorers and technical documentation for node operators, pools, exchanges and custodial infrastructure.
