During the migration to the new masternode system, there was a problem at block 469999 that caused the network to stop.  Please update all desktop wallets and masternodes to version 1.7.hotfix, which is available at this link: https://github.com/tecracoin/tecracoin/releases/tag/v1.7.hotfix
Mobile wallets update is not required!

Updating masternode on the server

1. Logging to the server by typing the command

ssh root@ip-of-your-server

- in place of the ip-of-your-server, type the appropriate IP-address

1.1 Stop running the server with the command

tecracoin-cli stop

2. Deleting old 1.7.0 binary files (whole folder with all files) - if there is also a bin folder in the root folder, delete it as well

rm -rf bin/

3. Downloading and extracting the updated binary files
3.1 Download the binary files:

 wget https://github.com/tecracoin/tecracoin/releases/download/v1.7.hotfix/tnode.tar.gz

3.2 Files extracting:

tar xzf downloaded-file-name 

4. Go to the .tecracoin folder and type the command 

cd /root/.tecracoin

5. Files deleting

rm peers.dat

rm banlist.dat

rm tncache.dat

rm mempool.dat

5.1 Folder deleting

rm -rd blocks/

rm -rd chainstate/

rm -rd evodb/

rm -rd llmq/

Going to the root folder by command

 cd $HOME

6.1 Edit the tecracoin.conf file with the command

 nano /root/.tecracoin/tecracoin.conf

 After typing this command the following window will appear

In place of the dots, the correct private keys should be entered

6.2 Then add the given nodes (such as in the attached image)

addnode=95.216.11.50
addnode=104.248.241.32
addnode=51.68.251.200
addnode=188.166.28.24
addnode=178.62.12.132
addnode=178.128.186.151
addnode=167.99.38.40
addnode=165.22.199.224
addnode=159.65.93.39
addnode=159.203.24.78
addnode=142.93.206.189

7. Launching the server with the block reindex
7.1 Go to folder with extracted files from step 3.2 and type command

 tecracoind -reindex

8. Synchronization can take some time, even 2-3 hours. Check whether the blocks have been synchronized correctly with the command

 tecracoin-cli getinfo 

(if the number of blocks is above 470000 the process has run correctly)

Desktop wallet update

1. Backup or copy the wallet.dat (our wallet) and tnode.conf (the configuration file) files to a secure place
The files should be located in the folder \AppData\Roaming\tecracoin

2. Delete the entire folder (remember to keep the files from step 1)

3. Download the updated QT wallet from this link https://github.com/tecracoin/tecracoin/releases/tag/v1.7.hotfix  (for windows: https://github.com/tecracoin/tecracoin/releases/download/v1.7.hotfix/tecracoin-1.7.0-win64-setup-unsigned.exe )

4. Install a new wallet from the link above and replace the files from step 1 (delete tnode.conf and wallet.dat files and paste the saved files from step 1)

5.  When you launch the wallet  you need to add nodes before the synchronization ends.
5.1 Hide the synchronization by clicking the button shown in the screenshot below5.2 Going to debug console (as it shown on the screen below)

5.3 Add all nodes one by one using the commands below

addnode 95.216.11.50 add
addnode 104.248.241.32 add
addnode 51.68.251.200 add
addnode 188.166.28.24 add
addnode 178.62.12.132 add
addnode 178.128.186.151 add
addnode 167.99.38.40 add
addnode 165.22.199.224 add
addnode 159.65.93.39 add
addnode 159.203.24.78 add
addnode 142.93.206.189 add

6. Check if the blocks have been synchronized correctly by entering a command in the wallet debug console

getinfo 

(if the number of blocks is more than 470000 the process has run correctly)
