Helium 部署 Validator

1. 生成 testnet 钱包

helium-wallet create basic --network testnet -o /path/to/save/wallet.key

helium-wallet -f /path/to/save/wallet.key info

> ~/helium/helium-wallet-rs/target/debug/helium-wallet create basic --network testnet -o testnet.key
Password: [hidden]
+-----------------------------------------------------+---------+--------+------------+
| Address                                             | Sharded | Verify | PwHash     |
+-----------------------------------------------------+---------+--------+------------+
| 1aCjBMAWymv9x7kXTvKVsTe7tBkSyWoR5uzkQ49SG1tKtYwYG6n | false   | true   | Argon2id13 |
+-----------------------------------------------------+---------+--------+------------+

2. 获取 TNT (测试币)

https://faucet.helium.wtf/ 填入钱包地址获取假币。等待 10 分钟左右，假币到帐了。可以发掘查询。

> ~/helium/helium-wallet-rs/target/debug/helium-wallet -f testnet.key balance                       
+-----------------------------------------------------+----------------+--------------+-----------------+
| Address                                             | Balance        | Data Credits | Security Tokens |
+-----------------------------------------------------+----------------+--------------+-----------------+
| 1aCjBMAWymv9x7kXTvKVsTe7tBkSyWoR5uzkQ49SG1tKtYwYG6n | 10005.00000000 | 0            | 0.00000000      |
+-----------------------------------------------------+----------------+--------------+-----------------+

3. 利用 docker 部署 validator

docker run -d --init \
--restart always \
--publish 2154:2154/tcp \
--name validator \
--mount type=bind,source=$HOME/helium/validator_data,target=/var/data \
quay.io/team-helium/validator:latest-val-amd64

加入自动升级守护：

docker run -d \
--restart always \
--name watchtower \
-v /var/run/docker.sock:/var/run/docker.sock \
containrrr/watchtower \
--cleanup \
--interval 1800

可以看到 2154 端口需要对外开放。并且支持 p2p 通信。

4. 质押 10000 HNT 使得 validator 生效

查看 validator 地址：

sudo docker exec validator miner peer addr                                     
/p2p/1YPws85sTKu9rf5gBo9JYCUE1muDDrBhVkjUphDnskkk55RruVf

质押并缴费：

helium-wallet -f /path/to/save/wallet.key validators stake 1YPws85sTKu9rf5gBo9JYCUE1muDDrBhVkjUphDnskkk55RruVf 10000 --commit
Password: [hidden]
+-----------+-----------------------------------------------------+
| Key       | Value                                               |
+-----------+-----------------------------------------------------+
| Validator | 1YPws85sTKu9rf5gBo9JYCUE1muDDrBhVkjUphDnskkk55RruVf |

| Fee       | 35000                                               |
+-----------+-----------------------------------------------------+
| Hash      | 594qDbvczOFIW1vQSOeRWXwTdF1SMqqAyQ2ZGV_ibHk         |
+-----------+-----------------------------------------------------+

5. 查看 validator 部署结果

validator 监听的端口会增多：

一晚上挖到几十个 TNT (测试币)

其他

• validator 的部署与挖矿功能解耦隔离，这样很方便做部署切换，validator 的生效与否决定权在钱包侧的 HNT 质押
• validator 的 stake
