Next Steps to Upgrade/Collect your Swap coins are:
1. Backup your Wallet and copy your Unspent Transactions ID’s
The most common methods of backing up your wallet include
backing up a wallet.dat file. this is a file that holds private keys to spend outputs, addresses, transaction information.
it has different location based on an operating system,
Mac OS X: ~/Library/Application Support/CBitcoin/
if you need more help finding this folder, see this link for more information
locate wallet.dat and securely copy it to another device only you have an access to.
note that Anyone that gets access to the unencrypted file will be able to steal your coins.
To restore the backup, simply copy your backed up wallet.dat over an existing one in the bitcoin data location.
BIP 32 is a method of determining key pairs from a single seed. This seed is used to generate a master private key (xprv) which then can be imported to any BIP 32 compliant HD wallet.
To backup your wallet either copy the master key to a text file and back it up to another device (encrypted of course) or create a QR code, print it and store it somewhere safe
To restore the backup, simply paste the xprv string to your wallet when asked to
Users who received CBTC after the FORK block block 536000(september 31’st 2018) will need to fill a form with a list of all their unspent transaction id’s to get their swap coins.
you can list your unspent transactions by running ./cbtc-cli listunspent
3. Install the New ClassicBitcoin ZClassic Fork Software for your operating system
you will need to also download the ZCashParams Keys file (~ 800mb)
4. Run cbtcd import your wallet backup, swap all your coins to a newly generated address and start mining to help secure the Network.
if you don not see your funds after synchronising your wallet, dont panic, it just means you received coins after the fork block(536000) and you will need to fill a form with your unspent TX ID to receive your Swap Coins.
