[Enhancement]: Rename api.clients.eigenda_client.IEigenDAClient.GetBlob as GetPayload

[bxue-l2]

Use case and current behavior

Similarly for PutBlob
Currently, the name is misleading. Because blob contains other metadata prepended to the user data.

In more details, eigenda_client does the following

1. rollup data
2. create a blob header containing rollup data length
3. do a codec on the (header || rollup date) by padding an empty byte for every 31 bytes.
4. to commit the polynomial, we have to pad the above data to next power of 2. Because if we want to open a point later, so it has to be the next power of 2. For most fraud proof use case, we treat the the processed data above as evaluation of a polynomial (if the data is not fault provable, it restriction can be removed)

Because of the step 2, GetBlob is incorrect, similarly PutBlob in incorrect.

Enhancement

Change the interface into PutUserData, GetUserData

Solution proposal

as above

+1. Either RollupData or RollupBlob or anything else to differentiate it from "Blobs" that are used inside the network.

[bxue-l2]

EigenDA can servers non-rollup users, making it more generic.

or clientData

@bxue-l2 Is the proposal to make this change to the v1 client?

For v2, it will be implemented as GetPayload
