Automatic Installation

Moniker yerine Validator isminizi yazıp enter basın.

Copy

bash <(wget -qO- https://raw.githubusercontent.com/CoinHuntersTR/props/main/AutoInstall/empeiria.sh)

Sync Node

Node ağ ile eşleşmiş olması gerekiyor. Bunun için emped status 2>&1 | jq komutunu çalıştırdığınızda false çıktısı vermesi gerekir. True çıktı alırsanız aşağıdaki adımlara devam etmeyin.

Run a Validator

Öncelikle kendimize bir cüzdan açıyoruz. wallet yerine bir tane cüzdan ismi belirliyoruz.

Copy

emped keys add wallet

Copy

emped tx staking create-validator \
--amount 1000000uempe \
--from wallet \
--commission-rate 0.1 \
--commission-max-rate 0.2 \
--commission-max-change-rate 0.01 \
--min-self-delegation 1 \
--pubkey $(emped tendermint show-validator) \
--moniker "Testnet" \
--identity "" \
--website "" \
--security-contact="" \
--details "" \
--chain-id empe-testnet-2 \
--gas auto --gas-adjustment 1.5 --fees 30uempe \
-y

wallet yerine belirlediğiniz cüzdan adını yazıyoruz. moniker yerine Validator ismini ekliyoruz. identity de keybase.io adresnden yükleyeceğiniz avatar'ın ID'sini ekliyoruz. website, yerine siteniz var ise onu, yoksa twitter vs. eklerseniz. Security-contact yerine mail adresinizi, details yerine istediğiniz bir açıklamayı yazabilirsiniz.
