I heard that Erasure coding is used for fault-tolerance of data in blockchain such as Hyperledger fabric.

 

However, I searched, but it is not easy to find related information.

 

I guess.. Is it because the file system where data is stored is a distributed file system such as HDFS, rather than using easure coding directly from Hyperledger fabric?

 

If not, does the Hyperledger fabric use its own easure coding to store transaction data, ledger, etc.? Then, where can I find the relevant information?

 

Regards.

You use erasure coding to avoid data duplication of data that is not used frequently, such as the blocks of the ledger.

However, to fetch the data you'd need to reconstruct it from several servers.

In fabric we don't use that, because of the complexity overhead and management overhead of keeping track of where each data chunk resides and when and to where we should replicate it when its availability becomes too scarce.
