This release brings our own unique Proof Of Work algorithm change (Cryptonight HeavyX), to try to prevent ASICs and or FPGAs from mining on the network. This will also mean we are now nicehash resistant.

Cryptonight HeavyX is an algorithm designed to run slower than Cryptonight V8. Cryptonight HeavyX is essentialy Cryptonight V8 with double the iterations, while keeping the same scratchpad size. There is also a few minor differences.

This means that your hardware will get around half the hashrate H/s that it used to while mining XCASH.

Because this is a new algorithm we have created XCASH Mining software (using forks from XMRig and XMR-STAK).

XCASH_ALL_Miner
XCASH_CPU_Miner

We will be submitting a request to the mining software to add our algorithm into their software. In the meantime you will need to use our forks of the software. The readme page has instructions for how to use the software.

Because we know this is a slight inconvenience, all of the XCASH mining software have been built with 0% fees.

X-CASH is also now switching to a 2 minute block time, in preparation for our version of DPOS.

Release note:

  • Changed POW algorithm from CNV8 to Cryptonight HeavyX
  • Change the block time from 1 minute to 2 minutes
  • Hard fork version 12

This is a mandatory update for everyone, whether you use the GUI or CLI, you need to update before block 281000 (Feburary 15, 2019) otherwise you will be on the wrong blockchain.

How to Upgrade / Install If you are using the GUI Wallet or CLI Wallet

For all operating systems - Upgrading

Download the .zip file for your operating system and unzip the folder. Then all the files into your current GUI or CLI Wallet folder and click on "replace all files" when your operating system asks you:

  • xcash-blockchain-export
  • xcash-blockchain-import
  • xcash-blockchain-mark-spent-outputs
  • xcash-blockchain-usage
  • xcashd
  • xcash-gen-trusted-multisig
  • xcash-wallet-cli
  • xcash-wallet-rpc
  • X-CASH_GUI_Wallet.exe

Upgrading for MacOSx

Download the installer (.pkg) file and run it. This will create a new (or update) X-CASH folder in your application folder. Then copy/paste your wallet files (walletname, walletname.txt, walletname.keys) to your newly created folder.

For all operating systems - Installing

Download the zip for your operating system and unzip the folder. Preferably close to the root C:/

If you are on Windows, always run X-CASH_GUI_Wallet.exe as admin (right-click > Run as administrator)

Note

If you are on Macosx or Linux, you may have to run additional commands. Open a terminal in your GUI folder directory and run the script.sh file:
chmod +x script.sh && ./script.sh
