To learn more about the validator activation process, see Deposit Process. See Check node and validator status for detailed status monitoring guidance. You can leave your execution client, beacon node, and validator client terminal windows open and running. Once your validator is activated, it will automatically begin proposing and validating blocks. Frequently asked questions How long does it take for Geth to transition from State heal in progress to fully synced?

If it remains in this state for more than a day, your disk might not be able to write data as fast as the chain head advances. The most straightforward way to resolve this is using an SSD. Why do you recommend putting everything on a single machine? Keeping all of your client software on a single machine keeps things simple, which aligns with our security best practices.

Run Prysm through Rosetta. See our open bug for more information. Do I need to configure my firewall? Can you mix and match networks between execution layer and consensus layer? See Nodes and networks for more information.

Can I stake with less than 32 ETH? Pooled staking lets you stake with less than 32 ETH. What should I do if I can't run a node using my own hardware? You can delegate hardware management to staking as a service providers. Can I use a light node with Prysm, or do I need to run a full execution node?

No - at this time, a full node is required. Yes, but your USB connection introduces a possible point of failure. Can I use a light client as my local execution client so I don't have to download so much data? You should see one account, which is the developer accounts mentioned earlier. The third command displays the genesis block, and you will see that the extra data also contains the developer account.

The accounts managed by the node can be controlled using the personal API. An important functionality of this API is that accounts can be locked, so that they can no longer be used. As an example, let us try to lock the developer account. So to unlock again, you will have to shutdown geth, start it again without the HTTP flags, attach again and execute the command personal. Finally, let us see how to use the console to create additional accounts and transfer Ether to them.

Do we have to say good-bye to our good old friend Brownie if we choose to work with geth? Fortunately the answer is no — Brownie is in fact smart enough and will automatically detect a running geth in fact, a running Ethereum client when it is started and use it instead of launching Ganache. Let us try this. Make sure that geth is running and start Brownie as usual. If everything works, Brownie will spit out a warning that the blockchain that it has detected has a non-zero length and greet you with the usual prompt.

Great, so let us transfer some Ether to a new account as we have done it before from the console to see that everything works. It appears that Brownie has created a transaction and sent it, but is now waiting for the receipt and does not receive it.

To understand the problem, let us switch again to a different terminal and start the geth console again. At the console prompt, inspect the pending transactions by running txpool The output should show you that there is one pending transaction which you can also inspect by using eth. If you look at this transaction for a second, you will find that there are two things that look suspicious.

First, the gas price for the transaction is zero. Second, the gas limit is incredibly high. If you inspect the last block that has been mined, you will find that the gas limit is exactly the gas limit of the last block that has been mined successfully. Why is this a problem? The gas limit for a new block is determined by geth aiming at a certain target value.

At the moment, this target value is lower than the gas limit of the genesis block, meaning that geth will try to decrease the gas limit with each new block the exact algorithm is here. Thus the gas limit for the new block that the miner tries to assemble is lower than that for the previous one and therefore lower than the gas limit of our transaction, so that the transaction will not fit into the block and the miner will ignore it.

Let us try to fix this. First, we need to replace our pending transaction. The easiest way to do this is to use the geth console. What we need to do is to get the transaction from the pool of pending transactions, correct the gas limit and increase the gas price, so that the miner will pick up this transaction instead of the previous one.

We also set the value to zero, so that the transaction will effectively be cancelled. After a few seconds, Brownie should note that the transaction has been dropped and stop waiting for a receipt. The reason for our problem is related to the way how Brownie determines the gas limit and gas price to be used for a transaction.

When a transaction is created , Brownie tries to figure out a gas limit and gas price from the network configuration. For the gas price, the default is zero. To make Brownie work with geth, we need to adjust both settings. In the console, enter network. For versions of Brownie newer than version 1. The transaction will still work the error comes from this line of the code which is executed in a separate thread initiated here , so the error message is only annoying, however you might want to downgrade to version 1.

Note that the settings for the gas price and the gas limit that we have made enough will be lost when we restart Brownie. In order to make these changes permanent, you can add them to the configuration file for Brownie. Specifically, Brownie will, upon startup, load configuration data from a file called brownie-config. This closes our post for today.
