Mintegra is a proof-of-work gemstone NFT collection built natively on Robinhood Chain. Every gem is mined through real Keccak-256 hashing in the browser. There is no presale, no whitelist and no sale of miner status. The collection has 5,550 gems across 10 epochs. Every mint splits 70% to staked gems by rarity weight and 30% to the treasury, recorded on-chain.
The 536 Sprint is the public miner-record board for epoch 2, running on Zealy until 31 October. Points are earned primarily by mining and staking a self-mined gem, not by buying one. A bought gem is only a gem; miner status is earned only by the wallet that mined it. At the time of filing, 581 of 5,550 gems have been mined and 529 remain in epoch 2 before gem #1110 closes the OG Miner window.
The sprint rewards position in the public miner record, priority reading at the Assay Desk, and recognition for verified miners. Mining is live at mintegra.tech/mine.
