Flux (ZelCash) Mining Ends – Pool Shutdown Completed
On October 20, 2025, mining for Flux (formerly ZelCash) officially ended on 2Miners. This was due to Flux migrating away from traditional Proof-of-Work (PoW) mining to the new Proof-of-Useful-Work v2 (PoUW v2) model via Proof of Nodes (PON).
Our Flux mining pools were shut down at 19:00 UTC on October 20 to ensure that all final payouts could be processed before block 2,020,000, at which point the chain hard-forked and traditional mining stopped entirely.
All balances above the minimum threshold of 10 FLUX were successfully paid out.
We’re sad to see Flux go, but if you’re looking for a new coin to mine, use 2CryptoCalc to find the most profitable options for your hardware.
Zcash (ZEC) Node Update – v6.10.0
The Zcash 6.10.0 release brings support for the upcoming NU6.1 network upgrade, which is scheduled to activate at block height 3,146,400 — expected around November 23, 2025.
All node operators must upgrade to v6.10.0 or later to remain compatible with the mainnet after the activation of NU6.1.
Included ZIPs (Zcash Improvement Proposals):
- ZIP 271 – Deferred Dev Fund Lockbox Disbursement:
This proposal creates a new Zcash Development Fund, managed through a lockbox system. The lockbox contains funds reserved for future network development, ensuring a consistent, transparent, and long-term funding mechanism for Zcash’s ongoing improvements. The fund includes all existing resources from the earlier Deferred Development Fund Lockbox (ZIP 1015) and future allocations that may accrue over time. - ZIP 1016 – Community and Coinholder Funding Model (partial):
This proposal focuses on decentralizing decision-making and strengthening the governance model around Zcash funding. It aims to increase transparency and give coinholders a more direct voice in how development funds are used. Without this update, block subsidies for the Zcash Community Grants and the Deferred Development Fund Lockbox (ZIP 2001) would have expired in November 2025, risking a funding gap for Zcash development organizations.
The changes introduced ensure funding continuity, clarify governance structures, and make the process more dynamic and accountable to the Zcash community.
These updates are critical for maintaining long-term project sustainability and restoring investor confidence. As a result of the NU6.1 upgrade announcement, ZEC saw a significant price increase — rising from roughly $130 to $443 within one month — making Zcash mining more profitable than it has been in years.
