Mandatory masternode update to v1.7.0.3


As we informed in September new masternode system registration will start at block 450000 (around 15. January) and will be enforced at block 470000 (around 15. February).

After block 450k versions older than v1.7.0.3 will stop syncing. There is no need to update mobile wallet. QT desktop wallet also need to be updated.

Update to new version need to be done BEFORE block 450k, then in between blocks 450k and 470k register masternode in new system.

After block 470k only masternodes registered in new system will earn.

Between block 450k and 470k masternodes registered in old (current) system will earn, but only those updated to

First run after update from 1.6.x will be longer, because of blockchain database reindex.

Downloads from Github: 

Steps to be done on masternode before block 450k

1.stop daemon
2.delete old versions and unpack new binary
4.start new binary

No changes in config files needed. Assuming, that tecracoind and tecracoin-cli binaries are in system path and you are in your home directory (/root if root, /home/username if username) update script can look like that:

#stop current node
teracoin-cli stop
#delete old downloads
rm -f tnode.tar.*
#delete old binaries directories
rm -rf tecracoin-1.*
#download tnode binary (only tecracoind and tecracoin-cli)
#upnack binaries to bin directory, in most cases added to path after login
tar xzf tnode.tar.gz
#start new daemon

First run will take some time because of reindex.

Verify that new version is running”:
tecracoin-cli getinfo
 "version": 1070003,
 "protocolversion": 90030,

And that tnode is active:
tecracoin-cli tnode status
 "vin": "CtxIn(COutPoint(ff...ff, 1), scriptSig=)",
"service": "ip.address:2718",
"payee": "T………...",
"status": "Tnode successfully started"

After block 450k and before block 470k you need register masternode in new system like described in our article about version 1.7 (Core 14 update) [].

Masternode update on the server

1. Logging to the server by entering a command

ssh root@ip- of your server

- in field "ip-of your server", enter the corresponding ip address

1.1 Stop the server with the command

3. Downloading the updated binary files and unpacking them
3.1 Downloading binary files:


3.2 Unpacking the files:

tar xzf (binary file name) 

4. Navigate to the .tecracoin folder and enter the command

cd /root/.tecracoin

5. Deleting the files
