Mina

Mina is a proof-of-stake blockchain that stays tiny by using zero-knowledge proofs, so anyone can verify it; MINA pays fees and is staked.

Mina is a Layer 1 blockchain built around zero-knowledge proofs. Instead of storing every past block, it keeps a small proof that the whole chain is valid, so the chain stays a constant, small size and can be checked on ordinary devices. Developers build privacy-preserving apps on it, called zkApps.

MINA is the native token. It pays transaction fees and is staked under a version of the Ouroboros proof-of-stake protocol. Holders can delegate their whole balance to a block producer without moving their tokens, and can change or cancel delegation at any time. Mina has no slashing.

Mainnet launched in March 2021 with about 805 million MINA. There is no supply cap: new MINA is issued as block rewards, with a planned steady-state inflation of about 7%. The Mesa upgrade on 8 September 2026 halved slot times to 90 seconds and block rewards to 360 MINA.

o1Labs leads development and the Mina Foundation supports the ecosystem. App usage is still small, with about 53,000 zkApp transactions in 2025.
