Keryx KRX

Keryx (KRX) is an open-source Layer 1 BlockDAG network designed for decentralized and censorship-resistant AI inference. Its native currency, KRX, is used for mining rewards, network fees, inference payments and service-bond economics.

The network uses GHOSTDAG and operates at a target rate of 10 blocks per second. Keryx originally launched with the KeryxHash Proof-of-Work algorithm before upgrading to Proof-of-Model (PoM) in June 2026.

Proof-of-Model ties mining directly to possession of supported AI model weights. Participating GPUs keep a model resident in VRAM and perform a memory-hard data-dependent walk through those weights as part of block production. This links the network's mining capacity to hardware that is also capable of serving AI inference requests.

Keryx supports multiple model tiers based on GPU VRAM capacity. Miners can earn block rewards for participating in consensus and additional rewards for serving inference requests. Inference results are stored through IPFS, while compact references are committed to the Keryx network.

The current protocol uses service bonds to incentivize inference availability. A portion of each miner's block subsidy is temporarily locked as collateral, with penalties applied when miners advertise inference capabilities but repeatedly fail to serve assigned requests.

KRX follows a smooth emission schedule with an approximately four-year halving period. The main emission curve approaches roughly 9.9 billion KRX, followed by a permanent minimal tail emission. Transaction fees are burned, meaning KRX does not have a strict permanent maximum supply.

Keryx provides open-source node and mining software, desktop and mobile wallets, a BlockDAG explorer, network statistics and AI inference infrastructure. Development remains active and the protocol continues to evolve through network upgrades.
