A token you
actually mine.
KARIUM (KRM) is a Proof-of-work token on Solana with a 21M hard cap and a halving schedule. Supply is produced through Sol-Hash proof-of-work. No presale, no insiders, just fair, permissionless mining.
Proof-of-work on Solana.
Mine KARIUM using custom Sol-Hash algorithm—a GPU-optimized hash based on SHA3, Keccak, and Blake3. No ASIC centralization, just pure hardware mining. Secure the network, earn KRM, and participate in a fully decentralized ecosystem.
Generate
Miners hash a header containing previous block data, a timestamp, and a nonce. They continually increment the nonce until a valid hash is found.
Solve
When a hash meets the difficulty target, a block is solved. The difficulty dynamically adjusts every hour to ensure a target block time of 60 seconds.
Earn
Miners submit their solution to the smart contract. The first valid submission is rewarded with freshly minted KRM tokens directly to their wallet.
Retargets every hour.
To maintain stable network issuance, the algorithm evaluates the total hash rate across the network and adjusts the difficulty seamlessly without hard forks.
Block reward halves every ~3.5 months.
To emulate a Bitcoin-like deflationary asset, the block reward reduces by 50% periodically. This creates a predictable issuance schedule and long-term scarcity.
Your GPU is the rig.
The reference KRM miner is open source and cross-platform. Download the pre-compiled binaries for Ubuntu/macOS/Windows, fire up your CUDA or OpenCL card, plug in your Solana RPC, and start mining KRM right from your desktop terminal.
Fixed supply. No insider allocation.
The 21,000,000 total supply is hard-coded. There is no presale, no team allocation, no VC unlocks, and no central foundation. Every single KRM in circulation is mined by the community. A fully organic distribution running on the Solana blockchain.
Halving forever
Rewards decrease by 50% after every 150k blocks.
| Era | Reward | Blocks |
|---|---|---|
| Era 1 | 50 KRM | 0-150k |
| Era 2 | 25 KRM | 150k-300k |
| Era 3 | 12.5 KRM | 300k-450k |
| Era 4 | 6.25 KRM | 450k+ |
Cap enforced on-chain.
The token mint authority is assigned to the smart contract. It is impossible to mint past the 21M limit. The math guarantees strict scarcity.
Fair and auditable.
The entire source code is open and verified on-chain. There are no admin keys or hidden backdoors that can alter the supply schedule.
Supply you can verify first.
You do not need to trust a marketing site. Run the CLI tool to query the smart contract state directly from the Solana RPC.
