Hi guys,
We added replay attack protection option in Forknote. Now you can use it to safely send transactions to both chains if you have old wallet, without worrying someone will replay it on the concurrent blockchain.

Usage:

1. Download Forknote - https://github.com/forknote/forknote/releases/tag/2.1.2
2. Use the following config for the Quazarcoin Forknote blockchain - https://github.com/forknote/configs/blob/master/quazarcoin.replay_attack_protection.conf
3. Use the following config for the Quazarcoin Minergate blockchain - https://github.com/forknote/configs/blob/master/quazarcoin.minergate.replay_attack_protection.conf

Forknote will force you to mix your coins with outputs after the the fork height, making the transaction invalid on the other chain.
