Ethereum reindexing options: Understand when using reindex -chainstate -reindex
As a developer working with Ethereum, you probably know the importance of reindexation and chain state updates in maintaining a healthy and effective blockchain. However, understanding when to use "-reindex-chainstate" against "Reindex" is crucial to optimize your Ethereum development workflow. In this article, we will immerse ourselves in the differences between these two options and provide advice at the time of using it each.
** What is the update of the state of the chain?
The update of the state of the chain refers to the process of updating internal blockchain data structures, such as blocks, transactions and atmosphere, after the extraction of a block or a transaction. This ensures that all parties have the latest information on the blockchain.
When to use-reindex
TheReindexcommand is used to reindex updates of the condition of the chain from one location to another. When you want to carry out operations on several channels, such as synchronization with different testnets or integration with other blockchain platforms, the use of a single index file for all channels can be beneficial.
For example:
- You have two chains maintained Ethereum: Mainnet (the main chain) and Testnet 1.
- To synchronize the data of the two channels in a single index file.
- The use ofReindex -Chainstate” will create an index file which contains information on the two chain states, allowing you to easily access and update all the data.
When to use -reindex-chainstate '
The-Reindex-Chainstate ‘command is used to update the internal state of the Local Ethereum blockchain to correspond to the latest data from other channels. This option is useful when working with a single chain, such as Mainnet or Ropsten (a testnet).
For example:
- You build a decentralized application (DAPP) which wishes to update its internal data structures after synchronization with another channel.
- To make sure that the state of your DAPP remains in synchronization between the channels.

Is one of the options faster?
Generally, “Reindex-Chainstate” is faster than using “Reindex”. Indeed, it does not require synchronization of data from several channels in a single index file, which can be expensive in calculation.
However, when you need to synchronize data from several channels in a single index file or performance operations on all chain states simultaneously, “Reindex” could always be the best option. The speed difference between these two orders depends on your specific use case and your network conditions.
When each option should be used?
Use -reindex-chainstate when:
- You build a decentralized application (DAPP) which requires synchronization of local data between the channels.
- You must update the internal state of the local Ethereum blockchain to correspond to the latest data from other channels.
Use “Reindex” when:
- You have several main channels and want to synchronize their data in a single index file for easy access.
- You carry out operations on all simultaneous chain states or you must synchronize the data of several channels in a single index file.
In summary, understanding the differences between `-treindex ‘and’ -Redex-Chainstate is crucial to optimize your Ethereum development workflow.
