Step 0: Apply on our Website

Please visit TTC Representative Election

Step 1: Install gttc

Please follow the instructions on Building GTTC to install gttc on server (make sure is release/v0.2.1)

Step 2: Try Testnet (optional)

Please follow the instructions on TRY AS SUPERNODE ON TESTNET do connection test on our Testnet.

Step 3: Create your address

PLEASE MAKE SURE THE PRIVATE KEY OF THIS ADDRESS SECURITY !!!

DO NOT USE THE SAME ADDRESS ON TESTNET

DO NOT USE THE ADDRESS HAVE LARGE AMOUNT OF TTC

The address can be created by the gttc command or TTC Connect

Choice 1: Create your new account(address) by gttc

mkdir mynode
gttc --datadir mynode/ account new

Your new address will show on the screen, key file will be found in mynode/keystore/. Do not forget the password when you create this address, you need this password to unlock your account or get your private key from key file.

Choice 2: Use the address create on TTC Connect

1. Export your private key from TTC Connect
2. Build ethkey

cd $GOPATH/src/github.com/TTCECO/gttc/cmd/ethkey
go build 

3. Make key file from private key

echo 358af7a90596f0cee9d0a98ed24668096acd34dd353c79dacdb7b74e003a66f7 > pkfile
ethkey generate --privatekey pkfile
rm pkfile
mkdir mynode
mkdir mynode/keystore
mv keyfile.json mynode/keystore/

Please replace 358af7a90596f0cee9d0a98ed24668096acd34dd353c79dacdb7b74e003a66f7 with your own private key, make sure you remove your pkfile after create key file.

You could inspect your keystore file (or get your private key from key file)

ethkey inspect mynode/keystore/UTC--2019-04-04T23-12-39.782156000Z--217f8723d255f0ce25e1467f9cd35dd191ad029f --private

By type in your password, the result should like:

Passphrase: 
Address:        0x217F8723d255F0Ce25e1467f9CD35DD191AD029F
Public key:     0404e64f34abc2db1c828200382efae917f7bcada845a927fa4ee25a4a162bd80ac57d6e4473e88508e0a71fa1311cf8c45afc46fa2bc9777adc33aa5731baca97
Private key:    5b5100c2e4283f4208241267c4ce01a1582825372d53fbf87c7eee8a50cfda79

Please replace mynode/keystore/UTC--2019-04-04T23-12-39.782156000Z--217f8723d255f0ce25e1467f9cd35dd191ad029f with your own path.

Step 4: Run Supernode

Use the follow command to start node as super node

gttc --datadir mynode/ -unlock '1F1e2e04Fa8153C7349De27De87439E4a32c1Cd9' --password pass.txt --mine

replace 1F1e2e04Fa8153C7349De27De87439E4a32c1Cd9 with the address you create in last step, and make sure your password saved in pass.txt file

Now you will see the log like :

Means you sync block from our Mainnet.

Means you already try to seal block as supernode, but do not have enough vote till now.

Next Step: waiting for the election of supernode

First loop of vote will be on April 11 - April 15, 2019
