Ethereum: My Arbitrum Alchemy node is randomly returning -3 for block number

Error Node Alchema Ethereum Arbitrum: random lock number returns -3

As a developer of Ethereum, you are probably experiencing frustration with your Alchimy Arbitrum node. A common problem that is causing random returns of -3 per block_number is not a typical rate limit, but rather an erroneously configured or intermittent error. In this article, we will explore the possible causes and provide measures to solve the problem.

Understanding of the Ethereum network

Before immersing yourself in the problem, it is essential to understand how the Ethereum network works. The Ethereum Blockchain is made up of blocks, each containing a series of transactions. When performing a question for block_number, Alchemy returns an integer that represents the current block number in the chain.

configuration of the arbitrum node

Arbitrum is a level 2 downsizing solution that downloads some of the computational general expenses from the main Ethereum chain. The arbitrum node uses a similar architecture for Ethereum Mainnet, but is designed for faster and more efficient transactions. To configure your arbitrum node, you will have to:

• Install the arbitrum node software (Alrs) on the machine.

2

• Sets a test account or a portfolio for experimentation.

POSSIBLE CAUSES OF THE BLOCK number -3 Return

Several factors could contribute to random returns of the -3:

• Network congestion : If more users are questioning forblock_numberat the same time, it can lead to the congestion of the network, with consequent slower responses from alchemy.

• Problems of the RPC provider

  : Alchemy's RPC API could experience errors or timeouts, causing the return of the error code-3.

3

• Problems of recovery of Blockchain data : the arbitrum node may not have access to the latest blockchain data, with consequent slow responses or intermittent errors.

Problem resolution steps

To solve the problem, try the following:

• Check the congestion of the network : make sure there are no excessive connections to the provider of Alchimia RPC.

• Check the problems of the RPC provider : check the alchemy documentation for the error codes and the resolution of the specific problems for the node and the provider.

3

• RESTS THE STAFFUSION OF THE NODO : reviews and regulates the Settings of the Arbitrum node, including network addresses, timeout values ​​and blockchain data recovery settings.

• Test with a test account or a portfolio : Create a test account or use a different wallet to isolate the problem and confirm that it is not related to a specific user.

Conclusion

Therandomrandomly back to your alchimia arbitrum node can be caused by various factors, including the congestion of the network, the problems of the RPC provider, the incorrect configurations of the configurations of the node and the problems of recovery of the Blockchain data from your blockchain . Following these passages of resolution of problems and identifying potential causes, you should be able to solve the problem and obtain values ​​block_number accurate.
