[ANN] KERYX | Live AI Inference | Proof of Model | GPU PoW | 10 BPS

[HdCe]

With latest keryx-labs miner on windows downloading models is very slow and when downloading that 2200mb file whole miner closes/exits when approx. 1800mb of the file is downloaded.

I've released a new version of the miner:

https://github.com/ocminer/keryx-miner-supr/releases/tag/v.0.5.3

works on all pools, optimized also for AMD and most bugs should be ironed out.

I was using your miner.. just updated to 0.5.3 still same

I am getting "OPoI challenge in progress - PoW paused, stand by" and mining does not start. Sometimes mines for a while and then this message again. Also having "stratum message payload is empty". Using baikalmine pool.

What is causing this?

edit: tested suprnova.cc and it works.

Proof-of-Model (PoM)

Keryx was built for a single purpose: decentralized, uncensored AI inference. This means the network's value relies entirely on miners actually hosting the AI models. Until now, this was based on a "cooperative" model—relying on good faith. But good faith isn't security. Any pool or modified miner could simply strip the models away, collect rewards, and contribute absolutely nothing to the network's core mission.

PoM fixes this natively at the protocol level.

How it works: With PoM, the model is the proof-of-work. Mining becomes a memory-hard process that reads thousands of random chunks directly from the model weights stored in your GPU's VRAM. No weights in VRAM = no valid proof = no valid block. It is completely deterministic.

What it brings to the table:

- Pool-proof & Fork-proof: You cannot fake model possession or route around the system. Hold the model, or you don't mine.

- ASIC-resistant by design: The work is strictly bound to memory (weights) rather than raw compute power.

- Bigger model = bigger reward: Block rewards scale dynamically based on the model tier you prove you are hosting. This incentivizes miners to run heavier, more capable models instead of the lightest ones.

Honest scope:

PoM guarantees possession—proving that a miner genuinely holds a specific open model in VRAM. It does not yet verify that every inference output is correct; that is a separate layer currently under development. We'd rather ship a rock-solid guarantee today than overpromise.

The result: a network where mining and AI capability become one and the same. The hashrate is the model.

Holder-Reward — Keryx rewards those who hold the network

"Intelligence is the message. Those who carry it deserve to be rewarded."

We're rolling out a new economic mechanism: the Holder-Reward. The idea is simple — the more $KRX you hold, the more of your mining reward you keep.

The principle

On every block, the miner's share is scaled by a single ratio:

your $KRX balance  ÷  your production over the last 24h

In other words: how many days of your own mining output you're holding. The more you keep, the higher your rate climbs — up to 100 %. Whatever you don't hold is burned :fire:.

The brackets

HOLD (days of your output)   →   YOU KEEP
──────────────────────────────────────────
< 1 day                      →    40 %
≥ 1 day                      →    52 %
≥ 3 days                     →    64 %
≥ 1 week                     →    76 %
≥ 15 days                    →    88 %
≥ 1 month                    →   100 %

"1 day of output" = what your GPU mines in 24h. The bar scales automatically with your hashrate.

Why it's fair

The ratio is relative to YOUR production: a solo miner and a large farm follow exactly the same rule ("hold N days of your output"). No edge for the big players. Want the full rate? Hold ~1 month of what you mine.

What's in it for you

- No lock, no staking, non-custodial. Your coins stay 100 % yours, spendable anytime. The network just reads the balance of your payout address.
- Zero extra steps. No transaction, no signature — auto-binding happens on your payout address.
- Deflationary. The unkept delta is burned → $KRX scarcity rewards those who hold.

When

Activation: Friday, June 26, 2026, 18:00 UTC (DAA 37,780,000), as part of the upcoming hardfork.

Hold the network. The network holds you.
Keryx Node v1.2.7 — The Proof-of-Model Hardfork

⚠️ Mandatory upgrade — coordinated mainnet hardfork

▎ Activates at DAA 37,780,000 — Friday June 26, 2026, ~18:00 UTC.

This release changes the mining algorithm and activates three protocol upgrades at the same height. Every node must run v1.2.7, and every miner/pool must run a PoM-capable miner with the pinned models, before H — otherwise their blocks are rejected and they fork off the chain.

What activates at H

Proof-of-Model (PoM) — new mining algorithm

Replaces kHeavyHash. A valid block now carries a cryptographic proof of model possession: the miner proves it holds a specific open LLM in VRAM (Merkle-anchored weights, Fiat-Shamir witness verified after PoW, 100 % node-deterministic — the node never holds the weights).

- 1 GPU = 1 tier: Gemma-3-4B → Dolphin-Llama3-8B → Qwen3-32B → Llama-3.3-70B
- Pool-proof, fork-proof, genuinely anti-ASIC
- Scope honesty: PoM proves possession, not inference correctness (a separate, later layer).

OPoI v2 — uncensored model lineup

DAA-gated swap to the uncensored inference lineup.

💎 Holder-Reward — your miner cut, weighted by what you hold

Your share scales by your $KRX balance ÷ your own 24h production — i.e. how many days of your own output you hold. The shortfall is burned (deflationary). No lock, no staking, non-custodial, zero extra transaction.

< 1 day of your output → keep 40 %
≥ 1 day → 52 %
≥ 3 days → 64 %
≥ 1 week → 76 %
≥ 15 days → 88 %
≥ 1 month → 100 %

Tier-Reward — bigger model, bigger share

The miner cut also scales by your cryptographically proven PoM tier (6-point steps), compounding multiplicatively with Holder-Reward. Shortfall burned; total block reward unchanged.

Tier 0 — Gemma-3-4B → 82 %
Tier 1 — Dolphin-Llama3-8B → 88 %
Tier 2 — Qwen3-32B → 94 %
Tier 3 — Llama-3.3-70B → 100 %


Under the hood (since v1.2.6)

- PoM: PomProof transport over P2P (borsh) + RPC submit_block; weightless node-side verifier (blake3, seed-bound); per-tier R_T/N pinned; GPU-friendly mix64 seed/pow folds (K=256); kHeavyHash header check skipped under PoM.
- Holder-Reward (ratio-reward) full stack: per-SPK balance index kept in lockstep with the UTXO set; windowed-production index (O(1) slide + reorg-safe); consensus-safe inline bracket (no per-block store); fast-sync reconstruction from the pruning-point snapshot; full unit + E2E suite incl. reconstruction-equality.
- Consolidated hardfork activation banner.

Fixes

- sink_search VP-stall fixed (PoM-gated): reaches valid sinks hidden below disqualified blocks.
- Inference capability challenge: rotates on ai:cap change; re-challenge interval 6 min → 1 h.
- Docker: build the keryxd binary instead of kaspad — thanks @Namp88 (#10).

Upgrade instructions

- Node operators: pull v1.2.7, rebuild, restart before DAA 37,780,000.
- Miners & pools: switch to the v1.2.7 PoM miner with the pinned GGUF models loaded before H. A miner still on kHeavyHash — or without the models — has its blocks rejected after the fork.
