> Quai Network is a set of EVM-compatible blockchains that achieves 50k+ TPS without compromising decentralization.

The Subsidized Open-market Acquisition Protocol (SOAP), a major protocol upgrade that transforms merge-mining into a continuous QUAI buyback and revenue stream for the network, is scheduled to go live on Quai Network on December 17, 2025.

This launch marks a historic moment for Proof-of-Work innovation, enabling Quai Network to be mineable by SHA-256, Scrypt, and KawPow algorithms simultaneously.

What Makes SOAP Revolutionary?

SOAP introduces continuous buy pressure and long-term protocol support for QUAI through token buybacks from merge-mining.

Instead of routing parent chain subsidies to miners directly as in traditional merge-mining, SOAP routes 100% of the parent chain coinbase output to QUAI token buybacks. The purchased QUAI is then either burned or distributed through time-locked staking rewards. The currently supported parent chains include Bitcoin Cash, Litecoin, Dogecoin, and Ravencoin. 

Bottom line: SOAP converts external mining subsidies into an ongoing protocol revenue stream, ensuring the protocol benefits directly from external hashrate.

SHA and Scrypt Mining Now Available

With the mainnet launch of SOAP, miners using SHA-256 and Scrypt ASICs can now earn QUAI rewards. Miners simply point their existing rigs at Quai Network mining pools. This is a massive expansion of Quai’s mining surface, welcoming new communities of ASIC miners.

How Profitable Will It Be for Miners?

Wondering if mining QUAI is worth it for your hardware on launch day? We’ve got you covered.

Quai mining profitability will be tracked on Hashrate.no and WhatToMine covering all three algorithms:

  • KawPoW
  • SHA-256
  • Scrypt

Good news for GPU miners: KawPow, SHA-256, and Scrypt each operate on independent difficulty adjustment algorithms, so incoming ASIC hashrate won’t touch your rewards. And with increased emissions post-fork, GPU miners will actually earn more QUAI than before.

Mainnet Launch Details

  • Fork Activation Block Number: Prime 1171500 (December 17th, 2025 at ~ 9:30 AM CST / 15:30 UTC)
  • Protocol Transition from ProgPow to KawPow: Current GPU miners are required to migrate to KawPow immediately after the fork activation. There are no guarantees of ProgPoW pool support.

Launch Preparation: Pool Operators and Node Runners

Pool operators and node runners should update their infrastructure to the latest go-quai tag as soon as possible prior to launch day on December 17, 2025 to allow time for syncing. 

  1. Download v0.49.0 from the official release page
  2. Install the update using our installation guide
  3. Restart your node to apply changes

Use the network stats page to verify block height and sync status. For additional support, reach out via Discord.

Launch Preparation: Miners

SOAP is implemented via AuxPoW templates and standard Stratum v1 flows, meaning no firmware changes are required for miners.

The Project SOAP feature is currently being thoroughly tested on the Orchard testnet, which integrates with the mainnets of Bitcoin Cash, Litecoin, Dogecoin, and Ravencoin. If you would like to test your setup before the launch, you can plug into a SOAP-enabled pool.

Several pools, including Kryptex, HeroMiners, AlphaMine, and K1Pool, have already integrated SOAP on testnet. The team is currently assisting more pools to join upon mainnet.

You can find a mining setup guide in the official Quai documentation. If you need any help, head over to the Quai Discord, we’ll be glad to assist!

Conclusion

Project SOAP puts Quai on the way toward becoming the most economically resilient and hashrate-diverse PoW network in crypto. December 17, 2025 is the time to plug in and capitalize on this new opportunity early.

Security

All Quai Network blockchains are braided together, keeping the entire network censorship resistant and secure creating Scalable Proof-of-Work.

Decentralization

Quai allows anyone to participate in network governance by running a node or miner. With thousands of participants distributed across the globe, there is no single party with the ability to modify or turn off the network, ensuring zero network downtime.

Scalability

Quai Network automatically expands with demand to upwards of 50,000 TPS while keeping fees under $0.01.

Consensus

Transactions in Quai Network can be locally confirmed prior to global confirmation, offering high throughput with the shortest possible time to economic finality.

Shared Security

All blockchains within Quai Network share Proof-of-Work security through merged mining. Every Quai transaction is eventually confirmed by 100% of network hash power.

Merge-Mined Parachains

Parachains inherit security and interoperability by merged mining with Quai Network, and create new incentives for miners and users.

The Prime Chain

The Prime blockchain acts as the "knot" tying all Quai Network chains together. The Prime blockchain braids sub networks together, facilitating the transfer of data across chains.

Sub Networks

Quai's many high-speed sub networks independently and asynchronously process transactions. All sub networks are braided together by the Prime chain, ensuring shared security and interoperability across the network.
