What it is
Mina is a succinct blockchain: a lightweight payment-oriented proof-of-stake chain using recursively composed zk-SNARKs so the full chain stays constant-size (about 22KB) and verifiable in roughly 200ms on modest devices.
Technology & consensus
Ouroboros Samasika proof-of-stake consensus; block producers include zk-SNARKs produced by specialized snarkers compensated from transaction fees via a competitive snarketplace. A parallel scan state improves proving throughput.
Token utility
MINA is the payment currency for transaction fees and block and snark rewards. Holders stake or delegate to block producers to secure the network and earn inflation-funded rewards.
Key risks & notes
Supply is uncapped with ongoing inflation that dilutes non-stakers. The sophisticated proving system carries cryptography exposure. The protocol remains under active development. Much delegator reward distribution is handled off-chain at validator discretion.
