XPHash: Xphere's own blockchain mining algorithm and the first ASIC miner XP0

Most cryptocurrency projects borrow a proven solution from someone else when choosing a mining algorithm. Bitcoin uses SHA-256, Litecoin uses Scrypt, Ethereum Classic uses Ethash. Xphere went a different route: they wrote their own algorithm from scratch. It’s called XPHash, and in 2026 it even had its first dedicated ASIC miner — IceRiver XP0.

What is XPHash and why was it created?

XPHash is a proprietary Proof-of-Work algorithm developed exclusively for the Xphere (XP) network. It is not a fork of any existing algorithm — it was designed from scratch by the Xphere team with a specific goal: to separate mining from transactions while maintaining decentralization.

The entire Xphere 2.0 architecture is based on a two-chain arrangement. The Main Chain operates on the PBFT (Practical Byzantine Fault Tolerance) consensus, which ensures fast transaction processing. The second chain — Proof Chain — uses XPHash as a validator selection mechanism. Thus, miners in the Xphere network do not play the role of payment processors, but of a security layer that determines who is allowed to validate.

This combination is technically interesting: you get the speed of PBFT consensus without sacrificing decentralization, since joining the validator group is conditional on actual mining.

How XPHash works technically

XPHash is built on a Memory-Hard architecture . This means that the calculation requires high-bandwidth memory access — CPU or GPU processing power alone is not enough, memory throughput is key.

Why is this important? Memory-Hard algorithms are inherently more resistant to the dominance of cheap industrial hardware. A classic example is Ethash, which was designed to keep GPU mining viable for as long as possible. XPHash follows a similar path, but is optimized specifically for its own ASIC chip — not for GPU.

The result is an algorithm that:

• not efficiently minable on GPU or CPU after the network transition to ASIC Hardware,
• rewards energy efficiency before gross performance,
• serves as a validator selector, not just as protection against double-spend attacks.

The XPHERE Foundation has therefore intentionally discontinued the distribution of the official open-source mining client. Continuing to provide generic software that no longer reflects the real mining environment after the fork would mislead operators about the true economics and performance expectations.

IceRiver XP0: the first ASIC for XPHash

In May 2026, the manufacturer IceRiver launched the model XP0 — the first specialized ASIC miner in the world designed exclusively for the XPHash algorithm. This is a major milestone for the entire network: specialized hardware brings the network a higher hashrate, more stable difficulty, and security that general-purpose devices could never provide.

Technical parameters IceRiver XP0

What's interesting about the numbers?

The number 60 W is at ASIC miners. For comparison: Antminer S21 Pro on SHA-256 consumes over 3,500 W. Even the most economical Kaspa miners (such as IceRiver KS0 Ultra) operate at around 65–100 W. XP0 is thus at the absolute lower limit of consumption in the entire category ASIC device.

The noise level of 35 dB corresponds approximately to a quiet conversation or the noise of an air conditioner — the miner can be operated without any problems in an apartment, office or bedroom. No special wiring, soundproof room or industrial cooling is required. A standard 230 V socket is sufficient.

The energy efficiency of 0,4 J/GH is among the best values ​​in the home mining hardware segment.

Xphere 2.0: the context in which XP0 makes sense

To make it clear why ASIC was created right now, it is necessary to understand the current state of the project. At the end of May 2026, the XPHERE Foundation released an updated whitepaper X-Phere 2.0, which formally enshrines the two-chain architecture and defines the role of XPHash in the new consensus.

In June 2026, Web3Wave, a venture capital firm with over a decade of experience in supporting early-stage blockchain projects, joined the Xphere ecosystem. The XPHERE Foundation has committed 35 million XP to this collaboration.

This context is important for miners: XP0 is not coming out of nowhere. The project is actively building an ecosystem, attracting institutional interest, and at the same time, bringing to market the hardware the network needs to ensure security.

Who is IceRiver XP0 suitable for?

Domestic miners will appreciate the quiet operation and minimal consumption. With the price of electricity in the Czech Republic around 5–6 CZK/kWh, the monthly cost of electricity comes to approximately 200–240 CZK — significantly less than with any other ASIC devices on the market.

Novice miners get a plug-and-play device with an Ethernet connection that requires no technical knowledge beyond setting up a mining pool.

Crypto investors can view XP0 as a way to gain exposure to the Xphere project — instead of directly purchasing XP tokens, they accumulate coins through mining while contributing to the security of the network.

Conversely, for miners looking for immediate high profitability, XP0 comes with a relatively small project and higher risk. XP is a small-cap coin and profitability can change rapidly depending on the token price and network difficulty.

Summary

XPHash represents one of the few cases where a Layer 1 blockchain has actually written a mining algorithm from scratch — not just rebranded an existing solution. Its Memory-Hard design and role in validator selection make sense in the context of the two-chain architecture of Xphere 2.0.

The IceRiver XP0 is the logical outcome of this approach: the first dedicated ASIC for XPHash with extremely low power consumption (60 W), quiet operation (35 dB) and compact dimensions suitable for home use. The price of around 899 USD places it in the category of affordable hardware for individual miners.

Whether the investment is worthwhile depends mainly on the further development of the XP token price and the growth of the Xphere network. However, the technical side of the matter — both the algorithm and the hardware — is honestly worked out.
