节点运行快速入门

本节将演示部署一个bArtio测试网RPC归档节点，该节点包含beacond共识客户端和reth执行客户端。

注意：目前，测试网验证节点需被列入等候白名单，并在网络需要时运行。

先决条件

开始之前，请确保你的本地设备上满足以下条件：

  • Golang v1.22.0或更高版本

  • 满足最低硬件要求

  • 已安装Foundry (用于测试)

最低硬件要求

运行执行客户端和共识客户端均需要满足以下要求。建议在同一台设备运行这两个客户端，以实现两者之间的低延迟通信。

  • 支持的系统：Linux / MacOS

  • CPU架构：AMD64，ARM64或ARM64 Darwin

  • CPU性能：8核

  • 内存：48GB

  • 硬盘：1TB

如果以Docker容器运行，请确保每个Docker容器有足够的资源，以满足总需求。

源代码构建和运行

本节快速入门文档，将从源头构建共识客户端。

注意：请勿在Vscode中运行执行客户端或共识客户端，容易造成崩溃，请使用专业的Shell终端。

复制代码库并验证binary文件

首先，复制BeaconKit代码库，创建binary文件。

git clone https://github.com/berachain/beacon-kit;
cd beacon-kit;
make build;

# [Expected Output]:
# mkdir -p /path/to/beacon-kit/build/bin/
# Variables
# Building beacond/cmd
# ...
# go: downloading github.com/berachain/cosmos-sdk v0.46.0-beta2.0.20240624014538-75ba469b1881

这将创建一个位于./build/bin/beacond的本地binary文件。

接下来，运行以下代码，测试其是否正常工作：

# FROM: ./beacon-kit

./build/bin/beacond version;

# [Expected Output]:
# v0.2.0-alpha.1-172-g071b95a5

配置共识客户端

以下将演示配置一个BeaconKit共识客户端。

第 1 步：初始化信标节点

首先，为配置创建一个临时文件夹目录。此步骤可省略，但为了后续便利，创建临时文件夹以保存所有配置和数据库数据。

# FROM: ./beacon-kit

mkdir build/bin/config;
mkdir build/bin/config/beacond;
mkdir build/bin/config/reth;

接下来，使用所有标准数据初始化节点。

# FROM: ./beacon-kit

# Replace <YOUR_MONIKER_NAME> with a name of your choice.
MONIKER_NAME=<YOUR_NODE_MONIKER>; # Ex: MONIKER_NAME=BingBongNode
./build/bin/beacond init $MONIKER_NAME --chain-id bartio-beacon-80084 --consensus-key-algo bls12_381 --home ./build/bin/config/beacond;
# Ex: ./build/bin/beacond init BingBongNode --chain-id bartio-beacon-80084 --consensus-key-algo bls12_381 --home ./build/bin/config/beacond;

# [Expected Output]:
# {
#  "moniker": "BingBongNode", // <YOUR_MONIKER_NAME>
#  "chain_id": "bartio-beacon-80084",
#  "node_id": "72e2e6f9d667898d32ede54de9b9299eb567f692",
#  "gentxs_dir": "",
# ...

现在，应该能够在./build/bin/config文件夹中看到新创建的文件。

重要提示：运行验证器节点，务必安全备份priv_validator_key.json文件。该文件包含验证器的私钥，用于验证器对区块进行签名。如果丢失该文件，无人能提供帮助，你将永远无法恢复验证器及提取资产。

# FROM: ./beacon-kit

tree build/bin/config/beacond;

# [Expected Output]:
# build/bin/config/beacond
# ├── config
# │   ├── app.toml
# │   ├── client.toml
# │   ├── config.toml
# │   ├── genesis.json
# │   ├── node_key.json
# │   └── priv_validator_key.json <---- BACK THIS UP
# └── data
#     └── priv_validator_state.json

第 2 步：添加配置文件

首先，通过下载到config文件夹中的文件，恢复源文件：

# FROM: ./beacon-kit

curl -o "./build/bin/config/beacond/config/genesis.json" "https://raw.githubusercontent.com/berachain/beacon-kit/main/testing/networks/80084/genesis.json";

# [Expected Output]:
# % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
#                                  Dload  Upload   Total   Spent    Left  Speed
# 100 46860  100 46860    0     0   295k      0 --:--:-- --:--:-- --:--:--  293k

仔细检查源文件，确保类似于以下形式：

# FROM: ./beacon-kit

cat ./build/bin/config/beacond/config/genesis.json;

# [Expected Output]:
# {
#   "app_name": "beacond",
#   "app_version": "v0.2.0-alpha.0",
#   "genesis_time": "2024-06-05T14:00:00Z",
#   "chain_id": "bartio-beacon-80084",
#   "initial_height": 1,
#   "app_hash": null,
#   "app_state": {
# ...

接下来，恢复kzg可信设置：

# FROM: ./beacon-kit

curl -o "./build/bin/config/beacond/kzg-trusted-setup.json" "https://raw.githubusercontent.com/berachain/beacon-kit/main/testing/networks/80084/kzg-trusted-setup.json";

# [Expected Output]:
#   % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
#                                  Dload  Upload   Total   Spent    Left  Speed
# 100  436k  100  436k    0     0  2744k      0 --:--:-- --:--:-- --:--:-- 2747k

然后，从BeaconKit testnet repo恢复app.toml和config.toml数据：

# FROM: ./beacon-kit

# app.toml
curl -o "./build/bin/config/beacond/config/app.toml" "https://raw.githubusercontent.com/berachain/beacon-kit/main/testing/networks/80084/app.toml";

# config.toml
curl -o "./build/bin/config/beacond/config/config.toml" "https://raw.githubusercontent.com/berachain/beacon-kit/main/testing/networks/80084/config.toml";

通过添加moniker name和peers以修改配置。

如果你的设备不是MacOS系统，请将下方代码中的-i ''替换为-i 。

# FROM: ./beacon-kit

# Rename the moniker
MONIKER_NAME=<YOUR_NODE_MONIKER>; # Ex: MONIKER_NAME=BingBongNode
sed -i '' "s/^moniker = \".*\"/moniker = \"$MONIKER_NAME\"/" "$PWD/build/bin/config/beacond/config/config.toml";

# set jwt.hex path
JWT_PATH=$PWD/build/bin/config/beacond/jwt.hex; # generating in next step
sed -i '' "s|^jwt-secret-path = \".*\"|jwt-secret-path = \"$JWT_PATH\"|" "$PWD/build/bin/config/beacond/config/app.toml";

# seeds
# - Comma separated list of seeds
seeds_url="https://raw.githubusercontent.com/berachain/beacon-kit/main/testing/networks/80084/cl-seeds.txt";
seeds=$(curl -s "$seeds_url" | tail -n +2 | tr '\n' ',' | sed 's/,$//');
sed -i '' "s/^seeds = \".*\"/seeds = \"$seeds\"/" "$PWD/build/bin/config/beacond/config/config.toml";

# persistent peers
# - Comma separated list of nodes to keep persistent connections to
sed -i '' "s/^persistent_peers = \".*\"/persistent_peers = \"$seeds\"/" "$PWD/build/bin/config/beacond/config/config.toml";

第 3 步：生成JWT令牌

这将创建一个JSON Web令牌，以允许BeaconKit共识客户端与EVM执行客户端通信。

运行以下代码，创建JWT令牌：

# FROM: ./beacon-kit

./build/bin/beacond jwt generate -o ./build/bin/config/beacond/jwt.hex;

# [Expected Output]:
# Successfully wrote new JSON-RPC authentication secret to: ./build/bin/config/jwt.hex

这将创建一个jwt.hex文件，可以使用-o标签指定可选路径。如果不指定输出位置，则在beacond配置目录中生成，例如/root/.beacond/config/jwt.hex。

第 4 步：下载快照 (推荐操作)

强烈建议执行此步骤，以避免后续等待较长的同步时间。

从源资源库同步节点可能需要几小时，甚至几天，具体取决于带宽速度和peers数量。

参阅此处，获取快照链接列表：Berachain bArtio V2 Snapshots

运行以下代码，创建快照文件夹并下载快照文件：

# FROM: ./beacon-kit

mkdir snapshots;
curl -L EXAMPLE_SNAPSHOT_FILE.tar.lz4 > ./snapshots/EXAMPLE_SNAPSHOT_FILE.tar.lz4;

# [Example Output]:
#   % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
#                                  Dload  Upload   Total   Spent    Left  Speed
#   0 43.0G    0 78.1M    0     0  18.7M      0  0:39:07  0:00:04  0:39:03 18.7M

下载完成，解压快照文件并验证数据：

# FROM: ./beacon-kit

# make a directory and download snapshots
mkdir snapshots/tmp;
mkdir snapshots/tmp/beacond;
mkdir snapshots/tmp/reth;
# curl ...

# unzip
# - beacond
lz4 -dc < ./snapshots/EXAMPLE_SNAPSHOT_BEACOND.tar.lz4 | tar xvf - -C ./snapshots/tmp/beacond;
# [Expected Output]:
# ...
# x data/application.db/012580.sst
# x data/application.db/012780.sst
# x data/application.db/012421.sst
# x data/application.db/012420.sst

# - reth
lz4 -dc < ./snapshots/EXAMPLE_SNAPSHOT_RETH.tar.lz4 | tar xvf - -C ./snapshots/tmp/reth;
# [Expected Output]:
# ...
# x static_files/static_file_transactions_0_499999
# x static_files/static_file_receipts_1000000_1499999.off
# x static_files/static_file_headers_0_499999

快照文件应包含以下beacond和reth所需内容 (或相应EVM执行客户端所需内容)：

# ./snapshots/tmp/beacond - (needed folders & files)
# └── data
#     ├── application.db
#     ├── blobs
#     ├── blockstore.db
#     ├── cs.wal
#     ├── deposits.db
#     ├── evidence.db
#     ├── snapshots.db
#     ├── state.db
#     ├── tx_index.db
#     └── priv_validator_state.json
#
# ./snapshots/tmp/reth - (needed folders & files)
# ├── blobstore
# ├── db
# └── static_files

快照文件夹和快照文件验证完成后，将快照数据移入相应的配置文件夹。

# FROM: ./beacon-kit

# beacond
mv ./snapshots/tmp/beacond/data ./build/bin/config/beacond/data;

# reth
mv ./snapshots/tmp/reth/blobstore ./build/bin/config/reth/blobstore;
mv ./snapshots/tmp/reth/db ./build/bin/config/reth/db;
mv ./snapshots/tmp/reth/static_files ./build/bin/config/reth/static_files;

第 5 步：运行Beacon

配置好config.toml和app.toml文件后，运行以下代码，启动Beacon：

# FROM: ./beacon-kit

./build/bin/beacond start --home ./build/bin/config/beacond;

# [Expected Output]:
# ...
# INFO Starting service type=validator-updates-broker
# INFO Starting service type=engine-client
# INFO Initializing connection to the execution client... service=engine.client dial_url=http://localhost:8551
# INFO Waiting for execution client to start... 🍺🕔 service=engine.client dial_url=http://localhost:8551
# INFO Waiting for execution client to start... 🍺🕔 service=engine.client dial_url=http://localhost:8551

现在，你的BeaconKit共识客户端已配置完成，接下来配置执行客户端。

配置执行客户端

接下来，需要将执行客户端与beacond配对。

注意：所有基于以太坊的执行客户端均受支持！

然而，有些客户端可能需要更复杂的配置和微调，才能达到出块时间要求。因此，目前最推荐以下客户端：

下述示例中，将使用Reth作为执行客户端。

首先，新建一个终端会话，下载MacOS (基于苹果电脑芯片的操作系统) 的binary文件：

警告：本快速入门演示了如何在MacOS系统上运行节点，仅用于测试目的，不建议真实生产环境中在MacOS系统上运行节点。

# FROM: ./beacon-kit

curl -L https://github.com/paradigmxyz/reth/releases/download/v1.0.3/reth-v1.0.3-x86_64-apple-darwin.tar.gz > reth-v1.0.3-x86_64-apple-darwin.tar.gz;
tar -xzvf reth-v1.0.3-x86_64-apple-darwin.tar.gz;

# # [Expected Output]:
#   % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
#                                  Dload  Upload   Total   Spent    Left  Speed
#   0     0    0     0    0     0      0      0 --:--:-- --:--:-- --:--:--     0
# 100 20.6M  100 20.6M    0     0  47.5M      0 --:--:-- --:--:-- --:--:-- 47.5M
# x reth

运行以下代码，检查reth客户端是否正常工作：

# FROM: ./beacon-kit

./reth --version;

# [Expected Output]:
# reth Version: 1.0.0
# Commit SHA: 31e2470
# Build Timestamp: 2024-06-24T10:26:24.880668000Z
# Build Features: jemalloc
# Build Profile: maxperf

第 1 步：配置源文件

首先，从BeaconKit代码库下载eth创世源文件。

# FROM: ./beacon-kit

curl -o "./build/bin/config/reth/eth-genesis.json" "https://raw.githubusercontent.com/berachain/beacon-kit/main/testing/networks/80084/eth-genesis.json";

# [Expected Output]:
#   % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
#                                  Dload  Upload   Total   Spent    Left  Speed
# 100  7232  100  7232    0     0  42532      0 --:--:-- --:--:-- --:--:-- 42792

仔细检查源文件，确保类似于以下形式：

# FROM: ./beacon-kit

cat ./build/bin/config/reth/eth-genesis.json;

# [Expected Output]:
# {
#   "config": {
#     "chainId": 80084,
#     "homesteadBlock": 0,
#     "daoForkBlock": 0,
#     "daoForkSupport": true,
# ...

第 2 步：启动Reth

运行以下代码，完成剩余reth文件配置：

# FROM: ./beacon-kit

./reth init --datadir ./build/bin/config/reth --chain=./build/bin/config/reth/eth-genesis.json;

第 3 步：运行Reth客户端

# retrieve bootnode
bootnodes_url="https://raw.githubusercontent.com/berachain/beacon-kit/main/testing/networks/80084/el-bootnodes.txt";
bootnodes=$(curl -s "$bootnodes_url" | grep '^enode://' | tr '\n' ',' | sed 's/,$//');

# run reth
./reth node --authrpc.jwtsecret=./build/bin/config/beacond/jwt.hex \
--chain=./build/bin/config/reth/eth-genesis.json \
--datadir=./build/bin/config/reth \
--port=30303 \
--http \
--http.addr=0.0.0.0 \
--http.api="eth,net,web3,txpool,debug" \
--http.port=8545 \
--http.corsdomain="*" \
--bootnodes=$bootnodes \
--trusted-peers=$bootnodes \
--ws \
--ws.addr=0.0.0.0 \
--ws.port=8546 \
--ws.origins="*" \
--authrpc.addr=0.0.0.0 \
--authrpc.port=8551 \
--log.file.directory=./build/bin/config/reth/logs \
--metrics=0.0.0.0:6060;

# [Expected Output]:
# INFO Initialized tracing, debug log directory: ./build/bin/config/reth/logs/80084
# INFO Starting reth version="1.0.0 (31e2470)"
# INFO Opening database path="./build/bin/config/reth/db"
# INFO Configuration loaded path="./build/bin/config/reth/reth.toml"
# INFO Adding trusted nodes
# INFO Verifying storage consistency.
# INFO Database opened
# INFO Starting metrics endpoint addr=0.0.0.0:6060
# ...

检查同步状态

新建一个终端会话，并运行以下代码：

# Don't have jq? `brew install jq`;
./build/bin/beacond --home=./build/bin/config/beacond status | jq;

# [Expected Output]:
# {
#   "node_info": {
#     "protocol_version": {
#       "p2p": "9",
#       "block": "11",
#       "app": "0"
#     },

#     },
#     "voting_power": "0"
#   }
# }

测试本地RPC节点

现在，通过以下步骤来验证当前网络是否正常运行，需要执行一些RPC请求，并部署一个合约。

先决条件：在此之前，请确保节点同步已完成。

获取当前区块高度

curl --location 'http://localhost:8545' \
--header 'Content-Type: application/json' \
--data '{
	"jsonrpc":"2.0",
	"method":"eth_blockNumber",
	"params":[],
	"id":83
}';

# [Expected Output]:
# {
#     "jsonrpc": "2.0",
#     "result": "0xfae90",
#     "id": 83
# }
