When you run your own verifier node, the first thing to realize is that you are doing this to help network security, so you don't have to worry too much about uptime.

Assuming the overall health of the network (more than 2/3 nodes are always online and new blocks are being finalized), more than 50% online verifiers will see their rights and interests increasing.

Quote a sentence from the series of articles of ETH Staking Guide of Ethereum Foundation:

This lightens the burden of the verifier on client backup and network delay, because the punishment of being offline is not so serious.

There is little chance that you will be punished. ETH 2.0？ There is an incentive mechanism for collusion in the agreement, that is, the verifier related to the wrong time will be punished.

Punishment measures include: proportional reduction-the proportion of destroying ETH depends on the number of verifiers who have been fined recently; Inactive leakage-If more than 1/3 verifiers are offline and the blockchain cannot complete the blockade, offline verifiers will be severely punished.

Proportional punishment means that if a promised service provider fails all verifiers under its control due to bugs or attacks, they will lose more ETH than individuals who run verifier nodes independently.

In addition, if the infrastructure of giant whales and providers is completely paralyzed, they will also face the punishment of destruction and lose a lot of ETH.

Even if the provider carefully ensures the decentralization of geographical location and client software, it is difficult to avoid all attacks (social engineering, invasion of external attackers or evil of insiders).

Do you have the right to quit? ETH 2.0？ Verifier, you must pay attention to two things-signing the private key and revoking the private key.

Although the withdrawal private key must be mailed to get the funds back, you still need to sign the private key to start the operation of deactivating the verifier (etc.). ? ETH 2.0？ After entering the 1 phase, this rule will change).

If you choose to use a pledge service provider, you must hand over the control of the signature private key to the provider (if there are multiple copies of a signature private key, it is difficult for the provider to provide you with services free of fines).

In other words, if the provider is offline or you are not satisfied with its service, whether you can quit depends on the provider.

Although you can ask your provider to provide you with a signed exit channel key exchange key before submitting the pledge, this scheme is not foolproof. Once a hard fork occurs, this message will be invalid. This requires constantly tracking the effectiveness of this message or even multiple messages (not good from the perspective of user experience).

Pledge hardware is cheap and easy to use. Running the validator node yourself is not as scary or expensive as you think. Once? ETH 2.0？ On-line, you can run the verifier node on an old mobile phone or raspberry pie (100 USD).

We wrote a guide for developers (this one and this one respectively) on how to use Nimbus to run verifier nodes on Android. Before the main network, we have simplified this process as much as possible. In particular, the main network guide will be aimed at users who have no programming experience, and will try to "install+pledge ETH = normal operation".

It can help Ethereum to enhance its anti-attack ability. Instead of letting the same entity control 100 nodes, let one entity control one node. ——? Barnabe Munnott

In the long run, the higher the value of Ethereum, the stronger its anti-attack, and the higher the degree of decentralization of its knowledge layer.

Satoshi Nakamoto's original vision was "one CPU, one vote", but today's PoW system has deviated from this vision. At present, most mineral resources are concentrated in the hands of a few mineral pools. Individual miners join the mine pool to reduce the fluctuation of income.

The reason why we choose to switch from PoW mode to PoS mode is also to solve this problem.

If more and more people choose to run their own verifier nodes, we can turn this vision into reality, enhance the anti-attack of Ethereum, and make it develop continuously without censorship.
