比特币BTC相关服务 bitcore-node / insight 搭建
背景
作者：JKincsdn
由于BTC地址模型采用UTXO(即在钱包导入目标地址的前提下，节点只保存地址的所有交易记录)，所以通过节点无法直接读取地址余额。需要遍历UTXO列表进行累加计算出余额。
所以开源项目bitcore 诞生，bitcore 是基于nodejs 开发的提供开源的扫链、钱包、区块浏览器等综合服务
此项目依赖BTC节点 + mongodb(主要用于保存交易记录等信息，类似扫链数据库)
git clone https://github.com/JKinGH/bitcore.git
3. 环境准备
具体参考此项目Readme.md
3.1 安装 node官网地址，推荐使用v10.16.0
sudo su -
cd /usr/local
wget https://nodejs.org/dist/v10.16.0/node-v10.16.0-linux-x64.tar.xz
tar xf node-v10.16.0-linux-x64.tar.xz
mv node-v10.16.0-linux-x64 node
echo 'export PATH=/usr/local/node/bin' :$PATH>> /etc/profile
3.2 安装mongodb（docker运行）
拉取mongodb镜像
docker pull mongo:4.0.14-xenial
mongodb启动脚本如下
#!/bin/bash
#
basedir=/opt/docker-instances/mongodb
sudo docker run -d --name mongodb \
-v $basedir/data:/data/db \
-p 27017:27017 \
mongo:4.0.14-xenial
4. bitcore-node 配置文件
注意：
1. 配置文件必须是json格式，否则读取配置文件失败
2. 主要读取trustedPeers内容，即 BTC节点的P2P 地址、端口；RPC暂时没发现作用
3. 配置文件名称必须在bitcore目录下，并且名称为bitcore.config.json

"bitcoreNode": {
"modules": ["./bitcoin"],
"services": {
"api": {
"wallets": {
"allowCreationBeforeCompleteSync": true
}
}
},
"chains": {
"BTC": {
"regtest": {

{
"host": "127.0.0.1",
"port": 18444

"port": 18443,
"username": "xxx",
"password": "admin@123"
}
}
}
}
}
}
4.1 testnet (测试链、默认P2P/RPC端口 18333/18332)
{
"bitcoreNode": {
"modules": ["./bitcoin"],
"services": {
"api": {
"wallets": {
"allowCreationBeforeCompleteSync": true
}
}
},
"chains": {
"BTC": {
"testnet": {
"chainSource": "p2p",
"trustedPeers": [
{
"host": "127.0.0.1",
"port": 18333
}
],

"port": 18332,
"username": "xxx",
"password": "admin@123"
}
}
}
}
}
}
5. 启动 bitcore-node 服务(类似区块浏览器API)，默认端口 3000
API文档
cd bitcore/
npm run node //前台运行
可查看启动的相关信息
devops@hn-baas:~/bitcore$ npm run node
> @8.13.0 node /home/devops/bitcore
> cd packages/bitcore-node && npm start
> bitcore-node@8.13.0 start /home/devops/bitcore/packages/bitcore-node
> npm run tsc && node build/src/server.js
> bitcore-node@8.13.0 tsc /home/devops/bitcore/packages/bitcore-node
> npm run clean && tsc
> bitcore-node@8.13.0 clean /home/devops/bitcore/packages/bitcore-node
