XPHash and the IceRiver XP0: Xphere's mining algorithm and the first ASIC miner
XPHash is the Xphere blockchain's own mining algorithm (ticker XP), and the IceRiver XP0 is the first ASIC miner that computes it: 150 GH/s at a power draw of 60 W. Most projects borrow an algorithm – Bitcoin uses SHA-256, Litecoin uses Scrypt. Xphere has its own. For home miners the XP0 is an economical entry into mining, but its revenue stands or falls with the price of a small, young coin.
Summary
- XPHash is a Proof of Work algorithm that the Xphere network uses to select validators, not to process payments.
- The IceRiver XP0 was released in May 2026: 150 GH/s, 60 W, roughly 0.4 J/GH, 2.5 kg. The power supply is sold separately.
- Electricity costs roughly 220–260 CZK a month at 5–6 CZK/kWh.
- Main risks: the price of a small coin, a rapid rise in difficulty once machines are delivered, and dependence on a single hardware manufacturer.
What XPHash is and what it does in the Xphere network
Xphere is developed by the South Korean company Seoul Labs. The network runs on two chains. The main chain (Main Chain) runs on XPBFT consensus, a modified version of Practical Byzantine Fault Tolerance, and provides fast transaction confirmation. The second chain – the Proof Chain – uses Proof of Work with the XPHash algorithm to select validators.
So in the Xphere network, miners don't process payments as they do with Bitcoin. They form a security layer that determines who may validate. Entry into the validator set depends on actual mining, so the network shouldn't be closed to a narrow group.
According to a Nansen overview, XP has a hard cap of 5.5 billion coins, of which around 2.76 billion are in circulation, and half of the transaction fees are burned. The network is compatible with the Ethereum Virtual Machine (EVM).
IceRiver XP0: the first ASIC for XPHash
In May 2026 IceRiver began selling the XP0 – the first ASIC miner for XPHash. The manufacturer describes it as a custom edition for the Xphere network and states that it does not endorse any particular protocol or token. For the network, specialised hardware is a milestone: it brings higher hashrate, but at the same time ties mining to a single manufacturer.

| Power | 60 W (±10 %) |
| Energy efficiency | approximately 0.4 J/GH (our calculation) |
| Weight | 2.5 kg |
| Dimensions | 200 × 194 × 74 mm |
| Power supply | 100–240 V with PSU, 19–20 V DC without PSU; the 90 W PSU is sold separately |
| Operating temperature | 0–40 °C |
| Connectivity | Ethernet |
| Manufacturer's warranty | 180 days from shipment |
What stands out in the numbers
60 W is an unusual figure for an ASIC miner. For comparison: the Antminer S21 Pro at 234 TH/s draws around 3,500 W at 15 J/TH. The XP0 therefore uses roughly sixty times less and plugs into an ordinary socket without any changes to your wiring.
The manufacturer doesn't state the noise level, and sellers and reviews disagree on the figures. That's why we don't give one. At 60 W, however, the XP0 needs only a small fan, not industrial cooling like large ASIC miners.
Xphere 2.0: the context in which the XP0 was created
In the second quarter of 2026 the project released a reworked Xphere 2.0 whitepaper. The XPHash algorithm was publicly unveiled on 14 May 2026, and IceRiver started selling the XP0 within a few days.
According to Nansen's quarterly report, Web3Wave entered the ecosystem with its own contribution of 70 million XP, and the Xphere foundation entrusted 35 million XP to TokenPost Labs. For miners this signals that the project is building an ecosystem. Independently verifiable results – liquidity, the number of applications, validator decentralisation – remain to be seen.
Who the IceRiver XP0 is suitable for
Home miners will appreciate the small size and minimal power draw. The XP0 uses about 43 kWh a month, which at an electricity price of 5–6 CZK/kWh comes to roughly 220–260 CZK. How to calculate home mining in the Czech Republic in general is covered in the article Crypto mining at home.
Beginners get a “plug in and mine” device with an Ethernet connection. As a training machine the XP0 is excellent: you'll learn to set up a pool and a wallet and to monitor hashrate on a real machine. The manufacturer sold it for 899 USD excluding shipping, customs and VAT, i.e. a fraction of the price of industrial machines. It doesn't need 3–3.5 kW, so you don't have to rework your wiring.
Those interested in the Xphere project can treat the XP0 as a way to acquire XP coins continuously through mining instead of buying them on an exchange.
The XP0 is not suitable for those looking for an immediately high and stable return. XP is a coin with a small market capitalisation, and profitability can change quickly with both price and difficulty.
How to start: pool, wallet and explorer
The manufacturer doesn't recommend any particular pool for the XP0, and various addresses appear in guides abroad. So choose a pool based on current information on the project's official website (x-phere.com) and, before connecting, check that it actually pays out – for example in the network explorer xp.tamsa.io. How pool payouts work is explained in the article PPS and PPLNS.
Risks: what the first months have shown
At launch the numbers looked tempting. With exclusive algorithms, however, early returns don't usually last long. According to Nansen, XP started the second quarter of 2026 at around 0.0078 USD, climbed to roughly 0.08 USD on 16 May and ended the quarter in the 0.016–0.030 USD range.
- The price of a young coin. XP is highly volatile. Early on, the price can be moved by large miners who got in first and are selling.
- A sharp rise in difficulty. Once machines reach all buyers, network difficulty will rise. What earns well in the first weeks may earn a fraction a few months later.
- One manufacturer and one algorithm. The XP0 can't mine any other coin. If the project stalls or changes its rules, the machine has nowhere to go. The case of InitVerse and INIBOX showed how that can end.
- Low liquidity. Mined XP has to be sold somewhere. With low trading volume, a larger sale can push the price down.
Mining with the XP0 is therefore more of a cheap and convenient “lottery” with valuable experience than a source of regular income. Always check the current return on the pool and the XP price, and don't count on the figures from launch time. This article is not investment advice.
What next
- Quiet miners for home mining – machines for established coins (Bitcoin, Litecoin, Dogecoin) that you can run at home.
- ASIC miner profitability – a live comparison of machine revenue, recalculated every hour according to price and difficulty.
