Babylon(巴比伦)是由斯坦福大学 David Tse 教授创立的基于Cosmos SDK的 L1 区块链，致力于扩展比特币安全性以保护去中心化世界。

目前，巴比伦包括两个协议：

1. 比特币时间戳：这个协议将任何数据（如PoS区块链）的简洁且可验证的时间戳发送到比特币；

2. 比特币质押：这个协议允许比特币资产为任何去中心化系统提供经济安全性，通过无需信任（自我保管）的质押方式。

Babylon将启用Bitcoin的质押，通过Babylon

• BTC 质押者可以在没有托管风险的情况下赚取收益。

• PoS 链可以通过比特币进行保护，无需任何更改。

• 无需桥接BTC，比特币资产仍保留在比特币上。

巴比伦目前完成了两轮融资,总共融资了2600万美元，Polychain, Hackvc等资本参与了投资，目前在测试网阶段。

根据官方消息，目前用户可以以如下几种方式参与巴比伦。

1）运行一个节点，甚至成为验证者。（https://docs.babylonchain.io/docs/user-guides/btc-timestamping-testnet/overview ）

2）作为比特币质押服务的用户参与。（请等待测试网的启动公告）

3） 在Babylon上开发DApps。（在 https://github.com/babylonchain/storage-contract 中提供了开发者的玩具示例）

4）连接到Cosmos链并连接到Babylon。

运行测试网验证人

目前的公共测试网不是激励性测试网。建议体验为主，为接下来的测试网做准备。

安装基础环境

安装go

sudo rm -rf /usr/local/go;
curl https://dl.google.com/go/go1.21.5.linux-amd64.tar.gz | sudo tar -C/usr/local -zxvf - ;
cat <<'EOF' >>$HOME/.bashrc
export GOROOT=/usr/local/go
export GOPATH=$HOME/go
export GO111MODULE=on
export PATH=$PATH:/usr/local/go/bin:$HOME/go/bin
EOF
source $HOME/.bashrc

安装完成后运行以下命令查看版本

go version

安装其他必要的环境

sudo apt-get update -y
sudo apt-get install curl build-essential jq git lz4 -y;

下载源代码并编译

cd
git clone https://github.com/babylonchain/babylon.git
cd babylon
git checkout v0.7.2
make install

安装完成后可以运行 babylond version检查是否安装成功。

显示应为v0.7.2

检查同步状态

curl -s localhost:26657/status | jq .result | jq .sync_info

同步需要一段时间，其中显示 "catching_up":显示为false且 latest_block_height 和区块浏览器https://babylon.explorers.guru/ 的最新区块接近即已经同步上。

从快照重新同步

当日志里看到类似

ERR Error in validation err="wrong Block.Header.LastResultsHash.  Expected 3645B015E73E39C42F0F1376A436A34DA6DE6DD074D61A97E455F9CCA17E1E69, got C3A1C86AEC71816A78DEA803E57892F4D0ADFC92C36B16B4D0DE5550E7541C73" module=blockchain

并且区块高度不能增长，需要确认你目前使用的babylond版本为0.7.2 ，并且需要从快照重新同步。

sudo systemctl stop babylond.service
cp $HOME/.babylond/data/priv_validator_state.json $HOME/.babylond/priv_validator_state.json.backup

mv $HOME/.babylond/priv_validator_state.json.backup $HOME/.babylond/data/priv_validator_state.json
sudo systemctl restart babylond.service 

如果区块高度一直不增长，并且

curl -sS http://127.0.0.1:26657/net_info | jq -r '.result.peers[] | "\(.node_info.id)@\(.remote_ip):\(.node_info.listen_addr)"' | awk -F ':' '{print $1":"$(NF)}‘

返回的peer就1，2个的话，说明你连接不到Peer，可以在discord搜一搜别人提供的peer和addrbook（大部分peer都连不上，可能因为节点太多，大部分Peer都到了连接上限）

创建验证人

创建钱包

babylond  keys add 钱包名 --keyring-backend test

注意请保存助记词。若不保存，之后将无法恢复。

领取测试币

加入官方discord，get-a-role 频道点tech role 然后去 ⁠faucet 领

去faucet频道发

!faucet 你的babylon地址

节点同步之后可以用

babylond query bank balances 你的babylon地址

查询测试币余额。

创建BLS key

babylond create-bls-key 你的babylon地址

设置默认keyring-backend

babylond config keyring-backend test

修改app.toml中的key

keyname="你的钱包名"
sed -i 's/key-name = ""/key-name = "'"$keyname"'"/' ~/.babylond/config/app.toml

创建验证人

获取足够测试币，且节点完成同步后，可以创建验证人。只有质押量在前80的验证人才是活跃验证人。目前最低191个测试币

moniker=验证人名
chainid=bbn-test-2
wallet=钱包名
babylond tx checkpointing create-validator \
    --amount="1000000ubbn" \
    --pubkey=$(babylond tendermint show-validator) \
    --moniker $moniker \
    --chain-id=$chainid \
    --gas="auto" \
    --gas-adjustment=2 \
    --gas-prices="0.0025ubbn" \
    --keyring-backend=test \
    --from=$wallet \
    --commission-rate="0.10" \
    --commission-max-rate="0.20" \
    --commission-max-change-rate="0.01" \
    --min-self-delegation="1"

在babylon上，只有在一个纪元结束后才能成为验证者。对于测试网，一个纪元持续约 30 分钟。

之后可以去区块浏览器https://babylon.explorers.guru/validators 查看你的验证人是否创建成功。(由于验证者过多，不一定能很快显示在上面)

查看自己的验证人地址

babylond keys show  你的钱包名 -a --bech val

验证自己的验证人

babylond query  staking validator 验证者地址

正常情况会返回类似如下的结果。
