This is a full week’s notice to all Safex Cash miners. The Safex Blockchain will be hard forking on the 26th November 2018 on block 61660, to the latest Cryptonote Algorithm CN2/V8. **Please read the following instructions carefully** - You will need to confirm your selected mining software supports CN2/V8 and download the latest version. - For minimum downtime, you will need to be available to switch your mining software from CN1/V7 to CN2/V8 at block 61660. - Failure to update your mining software and switch algorithms after block 61660 will most likely result in you submitting incorrect hashes and lead to an auto-kick and ban from your pool. - CN2/V8 will produce a slightly lower hash rate by design, compared to CN1/V7 – do not panic. This is normal. - **Do not switch to CN2/V8 BEFORE block 61660, or remain on CN1/V7 after block 61660** Mining Pools confirmed ready for fork: - [CN Pool](https://safex.pool.cnpools.space/) - [CryptoMiningPools](https://safex.cryptominingpools.net/) - [Cool Pool](https://safex.cool-pool.net/) - [Safex News Pool](https://pool.safexnews.net/) - [Smart Coin Pool](https://safex.smartcoinpool.com/) Pool operators will need to update to the latest version of the Safex Node and Wallet RPC. [https://github.com/safex/safexcore](https://github.com/safex/safexcore) If you operate a pool and would like to confirm you are CN2/V8 ready, please email me asap – [pool@safexnews.net](mailto:pool@safexnews.net). – **XMRig - RUN AFTER BLOCK 61660** Download XMRig CPU [here](https://github.com/xmrig/xmrig/releases). Download XMRig Nvidia [here](https://github.com/xmrig/xmrig-nvidia/releases). Download XMRig AMD [here](https://github.com/xmrig/xmrig-amd/releases). NOTE - MAKE A BACKUP OF YOUR OLD CONFIG.JSON BEFORE REPLACING 1. Extract latest XMRig ZIP file 2. Edit config.json 3. Change **“algo”: “cryptonight”** to **“algo”: “cryptonight/2”** 4. All other setting should be the same as your previous config.json - same pool, username, password etc. – **XMR-STAK - RUN AFTER BLOCK 61660** Download latest version of XMR-STAK [here](https://github.com/fireice-uk/xmr-stak/releases). 1. Back up your previous XMR-Stak install - please make note of your pool, address, password etc, settings - they will be needed later. 2. Download and extract latest version of XMR-Stak 3. Run xmr-stak.exe - you will be given some options to follow > **Do you want to use the HTTP interface?** - Optional Yes or No > **Please enter the currency that you want to mine** - Cryptonight\_v8 > **Pool Address** - Enter the address of the pool you’re mining from > **Username** - This is your long Safex Cash address > **Password** - This can be left as “x” or used to identify your miner - E.G “Mining Rig 1” > **Rig identifier for pool-side statistics** - leave blank unless your pool allows it > **Does this pool port support TLS/SSL?** - No (unless you’re using the SSL port) > **Do you want to use nicehash on this pool?** - No > **Do you want to use multiple pools?** - No – **NICEHASH MINERS - CHANGE AFTER BLOCK 61660** - Ensure you mining contract ends before block 61660 or that you cancel the contract prior to the pool switching. - From the main dashboard menu click **For Buyers** -\> **My Pools** - Select the relevant Safex Cash mining pool. Click the grey Edit button - Under Algorithm - select Cryptonight V8 - Everything else remains the same - press Update Pool Going forward, you will have to start buying your hash power from the cryptonightv8 category. – **Safex Cash 1 Click CPU Miner** An updated version will be released on or before the 26th November. Instructions will be given closer to the time. ---

So I just downloaded the 1click miner today. I’m assuming it’s ok? It’s been running for a few hours now. Thanks ---

If you’ve downloaded the latest version, then it will be fine. ---

Thank you. I downloaded this one: > **[safex/safex\_miner](https://github.com/safex/safex_miner/releases/tag/v.0.0.1)** > > graphical user interface for mining safex cash. Contribute to safex/safex\_miner development by creating an account on GitHub. I found the link on the safexnews Youtube channel (looked on [safex.io](http://safex.io) but couldn’t find anything). It says it was released 22 days ago and the fork was yesterday so I thought that it would be a problem. Thanks for clarifying. ---
