基于区块链和隐私保护的分布式身份认证系统

测试环境

ubuntu 22.04

golang 1.18

fabric 2.4.3

因为fabric-sdk-go v1.0.0只支持到fabric2.4，golang的版本也不能太高，只推荐1.18

后续可能会使用Fabric Gateway取代fabric-sdk-go以支持最新的fabric

但目前暂时继续使用fabric2.4

1. 本地DID测试

执行

go mod tidy

运行本地DID测试

go test -v local_did_test.go

2. fabric2.4 环境测试搭建

2.1 克隆fabric-sample仓库

git clone https://github.com/hyperledger/fabric-samples.git
cd fabric-sample
git checkout v2.4.3

2.2 下载二进制文件

wget https://github.com/hyperledger/fabric/releases/download/v2.4.3/hyperledger-fabric-linux-amd64-2.4.3.tar.gz
wget https://github.com/hyperledger/fabric-ca/releases/download/v1.5.3/hyperledger-fabric-ca-linux-amd64-1.5.3.tar.gz
tar xvzf hyperledger-fabric-linux-amd64-2.4.3.tar.gz
tar xvzf hyperledger-fabric-ca-linux-amd64-1.5.3.tar.gz
cd bin
export PATH=${PWD}:$PATH
cd ../

2.3 下载docker镜像

docker pull hyperledger/fabric-peer:2.4.3
docker pull hyperledger/fabric-orderer:2.4.3
docker pull hyperledger/fabric-ccenv:2.4.3
docker pull hyperledger/fabric-tools:2.4.3
docker pull hyperledger/fabric-baseos:2.4.3
docker pull hyperledger/fabric-ca:1.5.3

docker tag hyperledger/fabric-peer:2.4.3 hyperledger/fabric-peer
docker tag hyperledger/fabric-peer:2.4.3 hyperledger/fabric-peer:2.4
docker tag hyperledger/fabric-orderer:2.4.3 hyperledger/fabric-orderer
docker tag hyperledger/fabric-orderer:2.4.3 hyperledger/fabric-orderer:2.4
docker tag hyperledger/fabric-ccenv:2.4.3 hyperledger/fabric-ccenv
docker tag hyperledger/fabric-ccenv:2.4.3 hyperledger/fabric-ccenv:2.4
docker tag hyperledger/fabric-tools:2.4.3 hyperledger/fabric-tools
docker tag hyperledger/fabric-tools:2.4.3 hyperledger/fabric-tools:2.4
docker tag hyperledger/fabric-baseos:2.4.3 hyperledger/fabric-baseos
docker tag hyperledger/fabric-baseos:2.4.3 hyperledger/fabric-baseos:2.4
docker tag hyperledger/fabric-ca:1.5.3 hyperledger/fabric-ca
docker tag hyperledger/fabric-ca:1.5.3 hyperledger/fabric-ca:1.5

2.3 启动fabric测试网络

cd test-network
./network.sh down
./network.sh up

2.4 创建通道

./network.sh createChannel

2.5 部署测试链码

./network.sh deployCC -ccn basic -ccp ../asset-transfer-basic/chaincode-go -ccl go

3. 部署DID链码到fabric

3.1 复制fabric-did目录下的contract到test-network

cp -r {repo_path}/contract .
cd contract/
go mod tidy
go mod vendor
cd ..

3.2 安装DID链码

./network.sh deployCC -ccn did -ccp contract -ccl go

4. 测试fabric-sdk的功能

4.1 复制test-network/organizations/*到fabric-did/config目录下

cd fabric-did/config
cp -r {fabric-sample-path}/test-network/organizations/* .
cd ../

4.2 运行测试

go test -v  -run=TestGetBlockData

如果遇到网络问题，可能需要设置host

{fabric_ip}     peer0.org1.example.com
{fabric_ip}     peer0.org2.example.com
{fabric_ip}     orderer.example.com

5. 测试fabric_did的功能

go test -v  -run=TestCreateDID 

上述只是实现了did和vc的链上存储和验证，隐私保护、身份认证等功能敬请期待。
