Установка hermes Neutron , запуск validator_test !!!

Ретранслятор IBC - это автономный процесс, ответственный за ретрансляцию дейтаграмм IBC между любыми двумя цепочками. Способ, которым это делается, заключается в сканировании состояний цепочки, построении транзакций на основе этих состояний и отправке транзакций в цепочки, участвующие в сети.

переходим по ссылке и загружаем артифакт на свой сервер

https://github.com/neutron-org/neutron-contracts/blob/neutron_audit_oak_19_09_2022_fixes/artifacts/neutron_validators_test.wasm

загружаем и запускаем контракт

wget https://raw.githubusercontent.com/neutron-org/neutron-contracts/neutron_audit_oak_19_09_2022_fixes/validator_test_upload_contract.sh

chmod +x validator_test_upload_contract.sh

./validator_test_upload_contract.sh

./validator_test_upload_contract.sh /root/neutron_validators_test.wasm

пополняем баланс и сохраняем адрес контракта

устанавливаем hermes

curl -L "https://github.com/informalsystems/hermes/releases/download/v1.0.0/hermes-v1.0.0-x86_64-unknown-linux-gnu.tar.gz" > hermes.tar.gz && \
    tar -C ./ -vxzf hermes.tar.gz && \
    rm -f hermes.tar.gz  && \
    sudo mv ./hermes /usr/local/bin/ && \
    sudo chgrp root /usr/local/bin/hermes && \
    sudo chown root /usr/local/bin/hermes

проверяем версию

hermes --version

создаем папку для конфига

cd ~/
mkdir ~/.hermes

правим и создаем конфигурационный файл ( не забудьте указать свой контракт)

создаем связь между сетями ,выбираем одну (интересует только connection_id ( в связке а)

hermes create connection --a-chain quark-1 --b-chain theta-testnet-001

hermes create connection --a-chain quark-1 --b-chain uni-5

Сохраните где-нибудь вновь созданный нейтрон `connection_id` — он необходим для запуска тестового скрипта

стоп сервис ( использовать опционально)

systemctl stop neutron-ibc-cosmoshub-relayer.service

запускаем сервис

sudo systemctl daemon-reload
sudo systemctl enable neutron-ibc-cosmoshub-relayer.service
sudo systemctl start neutron-ibc-cosmoshub-relayer.service && journalctl -u neutron-ibc-cosmoshub-relayer -f -o cat

проверка статуса

sudo systemctl status neutron-ibc-cosmoshub-relayer.service

УСТАНАВЛИВАЕМ И ЗАПУСКАЕМ ICQ

https://teletype.in/@aktiv2332/8RjCKiOOcom

скачиваем скрипт

wget https://raw.githubusercontent.com/neutron-org/neutron-contracts/neutron_audit_oak_19_09_2022_fixes/validator_test.sh

делаем файл исполняемым

chmod +x validator_test.sh

запускаем

./validator_test.sh <YOUR_CONNECTION_ID>

если все прошло успешно , получаем 6 хешей , заполняем форму
