Horizen (ZEN) Mining Ends – Pool Shutdown Completed
On July 22, 2025, mining of Horizen (ZEN) officially ended on 2Miners. This followed the project’s announcement of a major transition to the Base network (an Ethereum Layer 2 solution). As part of this strategic shift, the Horizen blockchain ceased operations at block 1,807,300, on July 23 at 6:00 UTC.
Our ZEN mining pool was shut down on July 22 at 12:00 UTC to allow for all final payouts to be processed before the hard fork.
Final payouts were sent to all miners successfully.
We are saddened by this abrupt change — the decision to migrate came as a surprise to us and the community. You can read more about Horizen’s upgrade on their official announcement page.
If you’re looking for an alternative Equihash coin to mine, we strongly recommend Zcash (ZEC). BTC payouts are available!
Flux v8.0.0 – Major Node Upgrade
The Flux development team has released Flux Daemon v8.0.0, a major upgrade that brings important structural changes ahead of the upcoming v9 fork planned for Q4 2025.
Key changes include:
- Block reward halving has been removed to stabilize node operations prior to the v9 upgrade.
- Support for 32-bit systems has been discontinued. Builds for i386 will no longer be provided.
- Improved chain analysis with getchaintips RPC now supporting block height filters for faster queries.
- GitHub Actions CI/CD integration replaces legacy CI systems for better automation, testing, and artifact management.
- Cross-compilation improvements for ARM64 and Windows binaries, including toolchain updates and fix for binary stripping.
- New Arcane Mode added with fArcane flag for advanced testing and benchmarking scenarios using UNMANAGED_FLUXBENCHD.
This release lays the groundwork for major architectural changes expected in Flux v9. All node operators are strongly encouraged to upgrade as soon as possible.
