Ethereum PoA private network

Build your own Ethereum Proof of Authority private network (devnet)

⚠️ This repo is outdated

Recommended to install Go-ethereum version 1.13

Since geth v1.14 Clique has been deprecated. By now Geth is not able to seal Ethash or Clique blocks. It only works in PoS mode and in concert with a consensus client.

How to run

Step 2: Initialize genesis block

geth --datadir ./ init ../genesis.json

Step 3: Run Ethereum protocol

geth --datadir ./ --networkid 3355 --unlock 0x8a710e458b2782ae3105a77b6cdb6a491901f64f --mine --miner.etherbase=0x8a710e458b2782ae3105a77b6cdb6a491901f64f --password ./password.txt --allow-insecure-unlock --nodiscover --syncmode full --ipcdisable --ws --ws.port 8510 --ws.api eth,net,web3,personal,admin,miner --ws.origins "*" --http --http.api admin,debug,web3,eth,txpool,personal,miner,net --http.corsdomain "*" --http.port 8511 --http.addr 127.0.0.1 --authrpc.port 8610 --port 30010

Run node 2

Open a new terminal and follow the steps below.

Step 1: Change the current working directory to node2

cd node2

Step 2: Initialize genesis block

geth --datadir ./ init ../genesis.json

Step 3: Run Ethereum protocol

geth --datadir ./ --networkid 3355 --unlock 0x41017ef54bb3be28cb5b869375d6eef883824efe --mine --miner.etherbase=0x41017ef54bb3be28cb5b869375d6eef883824efe --password ./password.txt --allow-insecure-unlock --nodiscover --syncmode full --ipcdisable --ws --ws.port 8520 --ws.api eth,net,web3,personal,admin,miner --ws.origins "*" --http --http.api admin,web3,eth,txpool,personal,miner,net --http.corsdomain "*" --http.port 8521 --http.addr 127.0.0.1 --authrpc.port 8620 --port 30020

Add peers

Get info of node1

Open a new terminal and follow the steps below.

Step 1: Attach to node1 using HTTP

geth attach http://127.0.0.1:8511

Step 2: Show enode of node1

admin.nodeInfo.enode

Example output of Step 2:

"enode://e6ab2cb96ec264c3b12b95aea457479a2aa845adfac572107a92688a9fee6aa12a64ed500206be4ca0cb1b33ffc6741703755992b3071667c903886b8e74b7a3@127.0.0.1:30010?discport=0"

Step 3: Copy enode output from Step 2 to your clipboard.

Add peer from node2

Open a new terminal and follow the steps below.

Step 1: Attach to node2 using HTTP

geth attach http://127.0.0.1:8521

Step 2: Add node1 to node 2 peers by paste enode of node1 from your clipboard.

admin.addPeer("enode://e6ab2cb96ec264c3b12b95aea457479a2aa845adfac572107a92688a9fee6aa12a64ed500206be4ca0cb1b33ffc6741703755992b3071667c903886b8e74b7a3@127.0.0.1:30010?discport=0")
