This release adds a change in the difficulty adjustment algorithm to improve reaction time after NiceHash pump attacks.

THIS IS A MANDATORY UPDATE, EVERYONE MUST UPDATE BEFORE ATTEMPTING TO SEND TRANSACTIONS.

DO NOT TRY TO WITHDRAW OR DEPOSIT FROM AN EXCHANGE UNTIL YOU CAN CONFIRM THEY ARE ON THE CORRECT FORK

The new difficulty algorithm is based on the LWMA-2 (Linear Weighted Moving Average) developed by Zawy12. It will provide a better response time to NiceHash attack by making the difficulty reflecting the real hash-rate quicker, avoiding an arbitrage where the "attacker" would mine a lot of blocks at low difficulty.

Following this update, the difficulty will start lowering to match the real network hash rate, putting the block time back to 1 minute, processing transactions back to the normal rate.

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-blackball
  • xcash-blockchain-export
  • xcash-blockchain-import
  • xcash-blockchain-usage
  • xcashd
  • xcash-gen-trusted-multisig
  • xcash-wallet-cli
