Steps to setup and run Erigon dev chain. This tutorial is made for macOS.
|
|
|
|
|
|
## 1. Clone and Build Erigon
|
|
Open terminal 1 and type the following command
|
|
|
|
```bash
|
|
git clone --recurse-submodules -j8 https://github.com/ledgerwatch/erigon.git
|
|
cd erigon
|
|
make erigon
|
|
```
|
|
|
|
|
|
## 2. Build RPC daemon
|
|
On the same terminal folder you can build the RPC daemon.
|
|
|
|
```bash
|
|
make rpcdaemon
|
|
```
|
|
|
|
## 3. Start Node 1
|
|
If everything is fine, by changing directory to erigon/build/bin you will see the two exec for erigon and rpc daemon.
|
|
On the terminal you can type the following command to start node1.
|
|
|
|
```bash
|
|
./erigon --datadir=dev --chain=dev --private.api.addr=localhost:9090 --mine
|
|
```
|
|
Or, you could start the rpcdaemon internally together
|
|
```bash
|
|
./erigon --datadir=dev --chain=dev --private.api.addr=localhost:9090 --mine --http.api=eth,erigon,web3,net,debug,trace,txpool,parity,admin --http.corsdomain="*"
|
|
```
|
|
|
|
Argument notes:
|
|
* datadir : Tells where the data is stored, default level is dev folder.
|
|
* chain : Tells that we want to run Erigon in the dev chain.
|
|
* private.api.addr=localhost:9090 : Tells where Eigon is going to listen for connections.
|
|
* mine : Add this if you want the node to mine.
|
|
* dev.period <number-of-seconds>: Add this to specify the timing interval among blocks. Number of seconds MUST be > 0 (if you want empty blocks) otherwise the default value 0 does not allow mining of empty blocks.
|
|
* http.api: List of services to start on http (rpc) access
|
|
|
|
The result will be something like this:
|
|
|
|
<img width="1652" alt="Node 1 start" src="https://user-images.githubusercontent.com/24697803/140478108-c93a131d-745d-45ac-a76f-9bb808e504df.png">
|
|
|
|
|
|
Now save the enode information generated in the logs, we will use this in a minute. Here there is an example.
|
|
```
|
|
enode://d30d079163d7b69fcb261c0538c0c3faba4fb4429652970e60fa25deb02a789b4811e98b468726ba0be63b9dc925a019f433177eb6b45c23bb78892f786d8f7a@127.0.0.1:53171
|
|
```
|
|
|
|
## 4. Start RPC daemon
|
|
|
|
Open terminal 2 and navigate to erigon/build/bin folder. Here type the following command
|
|
|
|
```bash
|
|
./rpcdaemon --datadir=dev --private.api.addr=localhost:9090 --http.api=eth,erigon,web3,net,debug,trace,txpool,parity
|
|
```
|
|
The result will look like this:
|
|
<img width="1636" alt="rpc daemon start" src="https://user-images.githubusercontent.com/24697803/140478408-ac1be94a-4a63-42c6-8673-e24decadd658.png">
|
|
|
|
|
|
|
|
## 5. Start Node 2
|
|
|
|
Node 2 has to connect to Node 1 in order to sync. As such, we will use the argument --staticpeers.
|
|
To tell Node 2 where Node 1 is we will use the Enode info of Node 1 we saved before.
|
|
|
|
Open terminal 3 and navigate to erigon/build/bin folder. Paste in the following command the Enode info and run it, be careful to remove the last part ?discport=0.
|
|
|
|
The node info of the first peer can also be obtained with an admin RPC call
|
|
```bash
|
|
curl -X POST -H "Content-Type: application/json" --data '{"jsonrpc": "2.0", "method": "admin_nodeInfo", "params": [], "id":83}' localhost:8545
|
|
```
|
|
|
|
```bash
|
|
./erigon --datadir=dev2 --chain=dev --private.api.addr=localhost:9091 \
|
|
--staticpeers="enode://d30d079163d7b69fcb261c0538c0c3faba4fb4429652970e60fa25deb02a789b4811e98b468726ba0be63b9dc925a019f433177eb6b45c23bb78892f786d8f7a@127.0.0.1:53171" \
|
|
--nodiscover
|
|
```
|
|
|
|
You might face a conflict with ports if you run it on the same machine. To specify different ports use, for instance ``--torrent.port 42079``, you might consider specifying all the other flags too: ``--port --http.port --authrpc.port ``
|
|
|
|
To check if the nodes are connected, you can go to the log of both nodes and look for the line
|
|
|
|
``` [p2p] GoodPeers eth66=1 ```
|
|
|
|
Note: this might take a while it is not instantaneous, also if you see a 1 on either one of the two the node is fine.
|
|
|
|
|
|
|
|
|
|
|
|
## 6. Interact with the node using RPC
|
|
|
|
Open a terminal 4 and type
|
|
|
|
```bash
|
|
curl -X POST -H "Content-Type: application/json" --data '{"jsonrpc": "2.0", "method": "eth_chainId", "params": [], "id":1}' localhost:8545
|
|
|
|
```
|
|
The result should look like this:
|
|
|
|
```json
|
|
{"jsonrpc":"2.0","id":1,"result":"0x539"}
|
|
```
|
|
|
|
Other commands you can try:
|
|
|
|
```bash
|
|
curl -X POST -H "Content-Type: application/json" --data '{"jsonrpc": "2.0", "method": "eth_gasPrice", "params": [], "id":1}' localhost:8545
|
|
```
|
|
```bash
|
|
curl -X POST -H "Content-Type: application/json" --data '{"jsonrpc": "2.0", "method": "eth_mining", "params": [], "id":1}' localhost:8545
|
|
```
|
|
```bash
|
|
curl -X POST -H "Content-Type: application/json" --data '{"jsonrpc": "2.0", "method": "eth_syncing", "params": [], "id":1}' localhost:8545
|
|
```
|
|
```bash
|
|
curl -X POST -H "Content-Type: application/json" --data '{"jsonrpc": "2.0", "method": "net_peerCount", "params": [], "id":74}' localhost:8545
|
|
```
|
|
```bash
|
|
curl -X POST -H "Content-Type: application/json" --data '{"jsonrpc": "2.0", "method": "eth_blockNumber", "params": [], "id":83}' localhost:8545
|
|
```
|
|
|
|
## 7. Send a transaction with MetaMask
|
|
|
|
Finally, we want to try sending a transaction between two accounts.
|
|
For this example we will use dev accounts retrieved from Erigon code:
|
|
|
|
* Account with balance (Dev 1)
|
|
* address = ``` 0x67b1d87101671b127f5f8714789C7192f7ad340e ```
|
|
* privateKey = ``` 26e86e45f6fc45ec6e2ecd128cec80fa1d1505e5507dcd2ae58c3130a7a97b48 ```
|
|
|
|
* Empty account (Dev 2)
|
|
* address = ``` 0xa94f5374Fce5edBC8E2a8697C15331677e6EbF0B ```
|
|
* privateKey = ``` 45a915e4d060149eb4365960e6a7a45f334393093061116b197e3240065ff2d8 ```
|
|
|
|
|
|
|
|
Now from MetaMask, you can import Dev 1 , and then send a transaction to pass some ethers from Dev 1 to Dev 2.
|
|
From the RPC daemon terminal, you will see something like this
|
|
|
|
<img width="1633" alt="Transaction example" src="https://user-images.githubusercontent.com/24697803/140479146-94b6e66c-22b7-4d8a-a160-b3643d27b612.png">
|
|
|
|
Finally you will see the ethers in the Dev 2 account balance.
|
|
|
|
|
|
|
|
## 7. Check a mined block
|
|
|
|
Now we want to check the creation of a new block and that all the nodes sync.
|
|
|
|
Below we can see that block 1 is created (blocn_num=1) and that the next block to be proposed increments from 1 to 2 ( block=2). The other nodes will see the same update.
|
|
|
|
