Pre requisites

1. Check OS version

Make sure the OSX version is 16.7+

$ uname -srm
Darwin 16.7.0 x86_64

2. Install Go distribution 1.13

Use Homebrew to install Golang 1.13.

$ brew install go@1.13
$ go version

3. Check Go version

Check the golang version. Make sure they are the following version number or above.

$ go version
go version go1.13 darwin/amd64

Pre-requisites on Ubuntu

1. Check Ubuntu version

Make sure your ubuntu version is 16.04+

$ cat /etc/issue
Ubuntu 16.04.3 LTS \n \l

2. Install git

$ sudo apt-get install -y git

3. Install Go distribution 1.13

$ curl -O https://storage.googleapis.com/golang/go1.13.5.linux-amd64.tar.gz
$ tar -xvf go1.13.5.linux-amd64.tar.gz
$ sudo chown -R root:root ./go
$ sudo mv go /usr/local
$ export GOPATH=$HOME/go
$ export PATH=$PATH:/usr/local/go/bin:$GOPATH/bin
$ source ~/.profile

Configure the node

See the documentation about config.json to understand what each parameter means on the configuration file.

If you would like to connect to testnet, do the following:

$ cp docs/testnet_config.json.sample config.json

If you would like to connect to mainnet, do the following:

$ cp docs/mainnet_config.json.sample config.json

Make sure to modify the parameters to what your own specification.

Build the node

1. Check Go version

Check the golang version. Make sure they are the following version number or above.

$ go version
go version go1.13.5 linux/amd64

If you cannot see the version number, there must be something wrong when install.

2. Clone source code

$ git clone https://github.com/elastos/Elastos.ELA.SideChain.ID.git

3. Make

Build the node.

$ cd Elastos.ELA.SideChain.ID
$ make

If you did not see any error message, congratulations, you have made the DID full node.

4. Run the node

Run the node.

$ ./did

Interact with the node

1. JSON RPC API of the node

Once the node is running successfully, you can access ELA Node's JSON RPC APIs:

Example 1: Get the hash of the most recent block

curl -H 'Content-Type: application/json' -H 'Accept:application/json' --data '{"method":"getbestblockhash"}' http://localhost:20606
{
    "error": null,
    "id": null,
    "jsonrpc": "2.0",
    "result": "c4e72359cbb128bca244a800fb36d71f64b834e20d437c25de6c62edc46196c7"
}

Example 2: Get the hash of the specific blockchain height

curl -H 'Content-Type: application/json' -H 'Accept:application/json' --data '{"method":"getblockhash","params":{"height":1}}' http://localhost:20606
{
    "error": null,
    "id": null,
    "jsonrpc": "2.0",
    "result": "71b422e09dcd2f749d2adc0086735c210084cdb6b59bd4cd42e50455d024a662"
}
