Solana: Address Lookup Table is not compressing address as per expected

SOLANA: the search table of the address is not compression addresses as expected

A recent transaction on the Solana Blockchain has highlighted a problem with the addresses search table, which is a critical component of the Defi (decentral finance) ecosystem. The problem arises when a user tries to view his address in Solana Explorer.

The transaction

On December 2, a developer shared a transaction on the Solana Blockchain Explorer, Explorer.solana.com, which showed a problem with the search table. In particular, the transaction involved sending a transaction with the following details:

* Transaction ID : `5FVQJXFFFFFFGMWQHH618KZZCNSHCMFDVY4XWNJBSNFNEQWPJ9R1FZSWRCYKSUDT4ZG3YAZEDVMAWHSPT2X '

* Cluster :decide

The problem

After examining the transaction, it became evident that the research addresses table was not compressing the addresses as expected. In Solana, the addresses are generally represented in a specific format that includes a checksum of the entire address, which is used to validate the authenticity and integrity of the transaction. However, when this checksum is calculated for an address, it does not always correspond to the original address.

The problem

The problem derives from the fact that the search table uses a simple hash function to calculate the checksum of each address. Although this approach may seem sufficient in many cases, it is not robust enough to manage certain types of addresses or on -board cases. In particular:

* Single -characters addresses : When using an address with single characters (for example,ABC`), the search table does not calculate the checksum correctly.

* Extensions of the address : Some Solana addresses have extensions that require additional data, which can be lost during the calculation of the checksum.

Conclusion

The problem with the search table of the address on Solana is important to highlight. While the blockchain design has many strengths, its dependence on a simple hash function for the calculation of checksum can lead to errors and inconsistencies in some cases. Developers and users should be aware of this potential problem when working with addresses on the Solana network.

Advice

To mitigate this problem, developers are recommended:

• Use more robust addresses formats, such as addresses or multi-character addresses with extensions.

• Implement further checks to verify the integrity of the address before using it for transactions.

In addition, users should be cautious when working with the addresses on the Solana network and consider the search for help from expert developers or Solana experts if they encounter problems relating to the search tables of the addresses.
