X-CASH 1.3.0 - Update of difficulty adjustment algorithm (LWMA)

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.

Changed bulletproofs block height and GUI fixes

This release is for updating of the bulletproofs release date, which is now scheduled for mid-November.

We also brought some fixes to the GUI, mainly being that when syncing your wallet cache when connecting to a remote node, it will stay on the progress bar page until the cache is synced, instead of going to the account summary and showing a 0 balance for a few minutes. Another fix would be that for some users, remote node wouldn't work at all. The issue comes from the fact that the wallet was created without a password. A password is now required at the creation of the wallet.

Anyone that encountered these issues should restore their wallet and secure it with a password.

This is a mandatory update for everyone, whether you use the GUI or CLI, you need to update before block 95000 (around September 30, 2018) otherwise you will be on the wrong blockchain.

All mining pool operators must also update the core code contained in the daemon (xcashd) and the RPC wallet (xcash-wallet-rpc) before block 95000 (around September 30, 2018) otherwise your mining pool will be mining the wrong blockchain.

GUI Update - Redesign of remote node page and bug fixes

This release is a GUI only update, and is not a mandatory update

This release includes a redesign of the remote node settings page. Users can still type a custom remote node, but now have the ability to choose an official remote node from a list, or choose the "best node" option, which allows the program to decide based on the users network and the official remote node load, which server would be best for the user at that specific time.

This release also fixes common problems that people have been having with the wallet. The most notable being the wallet may give an invalid seed or invalid password when using a path that contains non-latin characters.

Users can now use the GUI in paths containing non-latin characters, as well as use non-latin characters for their password. However, users can not use non-latin characters in the name of the wallet file. It is still recommended to avoid using any non-latin characters when possible with the GUI wallet.

Users can also now create a view only wallet in the GUI. This option only asks for the public address and view key, and allows a user to see their wallets transactions list and balance, without typing in their spend key or seed. Because of this the view only wallet will not be able to send out any transactions.

Users also have the option to send their full balance with a click of a button. This option will automatically calculate how much can be sent, with the fees, so the wallet is empty after the transfer.

Users can now press enter after typing the password, instead of having to click the continue button.

Here is a quick list of the changes in this version

• redesign of daemon settings page
• added an automatic selection option for remote nodes (set to default)
• added a list to choose an official remote node
• added a send full balance button to the send payments page
• added a view only wallet option when restoring keys, to create a view only wallet
• lets the user press the enter button after typing the password instead of having to click the button
• changed the XCA symbol to our official XCASH symbol
• automatically remove line breaks from the to address and payment id fields on the send payments page

Note

The view only wallet is only useful if its a wallet you never sent a transaction from, and you are using it to just see your incoming transactions. On an account that has had both incoming and outgoing transactions, the view only wallet will report the wrong balance, since this is a privacy coin. This is how the view only wallet works with the core code. If you are going to use the view only wallet, we suggest reading more on how it works as well as key images, and why it will report a wrong balance once you have outgoing transactions.

Rebase of core code to 12.3

This release is for the rebase of the core code to 12.3

This release also changes the block fork height for public transactions for better accuracy for October 1, 2018 release date. The new block height for public transactions will be at block 95000.

Since the GUI Wallet does not change, this is a CLI only release. However, both CLI and GUI users need to upgrade, since the GUI program needs the CLI core code in the folder to function.

This is a mandatory update for everyone, whether you use the GUI or CLI, you need to update before block 94740 (around September 29, 2018) otherwise you will be on the wrong blockchain.

All mining pool operators must also update the core code contained in the daemon (xcashd) and the RPC wallet (xcash-wallet-rpc) before block 94740 (around September 29, 2018) otherwise your mining pool will be mining the wrong blockchain.

Mac and Linux GUI, Linux build fix and blockheight public transactions update

This release is for the new Linux and Macosx GUI. It also adds some new features, bug fixes and code improvements for the all of the GUI wallets.

Those improvements are:
Automatically remove all line breaks so valid keys dont give "Invalid Keypairs" error
Added more detailed error reporting for invalid transactions, with a copy button
Added remote node save feature
Made the fine print notes easier to read on higher screen resolutions
Fixed an error where the wallet could close after it is done syncing when using a remote node
Fixed an error where sometimes it would not show the public address after restoring a wallet
Memory optimizations

This release also fixes the problems people have been having with the Linux binaries. They should now work on any Linux system.

This release also changes the block fork height for public transactions from block 62690 to block 94740. The roadmap has it scheduled for the end of September, but we noticed we set the block height for the end of August. This is why the block height had to be corrected to match the roadmap.

This is a mandatory update for everyone, whether you use the GUI or CLI, you need to update before block 62690 (around September 1st, 2018) otherwise you will be on the wrong block chain.

All mining pool operators must also updated their xcashd and xcash-wallet-rpc before block 62690 (around September 1st, 2018) otherwise your mining pool will be mining the wrong block chain.

How to Upgrade / Install If you are a GUI user

Note: when upgrading and copying your wallet files to the newly unzipped folder, make sure to grab all three files per wallet. So if my wallet is named wallet1 I need to copy over the following files

• wallet1
• wallet1.KEYS
• wallet1.txt

Windows

Unzip the folder. If you already have wallet files, make sure to copy those into the newly unzipped folder.

Macosx

• Download and unzip "X-CASH_CLI_Macosx_1.1.1.zip"
• Download and unzip "X-CASH_GUI_Macosx_1.1.1.zip"
• Place "xcash_wallet_2.app" in the "X-CASH_CLI_Macosx_1.1.1" folder;
• Open "terminal", type "cd", then one space;
• Drag and drop your X-CASH_GUI_Macosx_1.1.1 folder in the terminal window and press "enter". This will place your terminal in the wallet folder;
• Type "chmod +x script.sh && ./script.sh" then press enter. The prompt "Installation is Complete!" will appear. You can close the terminal now and start "X-CASH_GUI_Wallet.app"

Linux

Unzip the folder. Open a terminal in the folder and run chmod +x script.sh && ./script.sh The script will ask for your Linux user password, in order to copy system files, so make sure to type in your Linux user password. The script will then run chmod +x on all of the binaries. If you already have wallet files, make sure to copy those into the newly unzipped folder.

How to Upgrade / Install If your a CLI user

Windows

Unzip the folder. If you already have wallet files, make sure to copy those into the newly unzipped folder.

Macosx

Unzip the folder. Open a terminal in the folder and run chmod +x script.sh && ./script.sh The script just runs chmod +x on all of the binaries. If you already have wallet files, make sure to copy those into the newly unzipped folder.

Linux

Unzip the folder. Open a terminal in the folder and run chmod +x script.sh && ./script.sh The script just runs chmod +x on all of the binaries. If you already have wallet files, make sure to copy those into the newly unzipped folder.

GUI Wallet - Bug Fixes and Upgrades

This is a GUI wallet only release, so you do not need to do anything if you do not use the Windows GUI wallet

GUI Wallet 1.1.0 is available; this is a major release, we recommend all users to update their wallet.
Main updates are:

• Fixes a bug where the wallet was showing 0 balance while the address had received funds
• Payment system modifications to prevent potential bugs caused by high numbers of unspents
• Fixes a bug where the wallet was wrongly suggesting that the address is not deterministic
• Public Address now displayed on the Receive tab
• X-CASH Ticker updated to XCA
• Mnemonic Seed and spend key now available on the Setting tab
• Added a progress bar to the create wallet page

How to upgrade:
Usually you can just replace the "X-CASH_GUI_Wallet.exe" file on your computer with the new "X-CASH_GUI_Wallet.exe" file in the zip folder.

For this release you will need to:

• Recover the seed and backup your wallet files
• Delete the wallet files (AFTER you backed them up and have the seed)
• Restore your wallet using the new GUI wallet version, thus creating new wallet files
