I launched a private network by using geth --datadir data/node1 --http --dev --http.corsdomain "*" --http.api web3,eth,debug,personal,net,miner --allow-insecure-unlock --mine command.

I am able to attach to it geth attach http://localhost:8545

but the balance of the default account is only 1.15 ether:

eth.getBalance(eth.accounts[0]) 1.15792089237316195423570985008687907853269984665640564039457582226449518702905e+77

I'd like to give it more ethers so I run:

miner.start() null And I can see there is a warn in the node log:

INFO [11-28|20:29:38.512] Transaction pool price threshold updated price=1
INFO [11-28|20:29:38.512] Commit new mining work                   number=4 sealhash=73b6e7..5d8b72 uncles=0 txs=0 gas=0 fees=0 elapsed="174.436µs"
WARN [11-28|20:29:38.512] Block sealing failed                     err="sealing paused while waiting for transactions"

I wonder what the issue could be?

Perhaps you have not previously given permission for the miner to sign the genesis block. POA uses the Clique API to manage the seal list.

You can see more details in this manual: https://yenhuang.gitbooks.io/blockchain/content/interact-with-private-chain-on-android/build-the-private-chain.html

You can also top up your balance using:

eth.sendTransaction({from:eth.coinbase, to:eth.accounts[1], value: web3.toWei(0.05, "ether")})

  • Do I need to use genesis? I just use this command to launch the blockchain: `geth --datadir data/node1 --http --dev --http.corsdomain "*" --http.api web3,eth,debug,personal,net,miner --allow-insecure-unlock --mine`. And it doesn't have Clique API. How can I enable it? – Joey Yi Zhao Nov 28 '21 at 22:27
  • In general, it should be bundled with official releases Geth & Tools on the official website https://geth.ethereum.org/downloads/ – Dmitrii Dimtiks Nov 29 '21 at 09:41

but the balance of the default account is only 1.15 ether:

eth.getBalance(eth.accounts[0]) 1.15792089237316195423570985008687907853269984665640564039457582226449518702905e+77

I didn’t pay attention to it right away. But this is not 1.15 ETH, this is a huge number of ETH that will not end and you can transfer it from coinbase to other created accounts on your private network in dev mode.
