go-da

go-da defines a generic Data Availability interface for modular blockchains.

DA Interface

Method	Params	Return
MaxBlobSize		uint64
Get	ids []ID, namespace Namespace	[]Blobs
GetIDs	height uint64, namespace Namespace	[]ID
GetProofs	ids []id, namespace Namespace	[]Proof
Commit	blobs []Blob, namespace Namespace	[]Commitment
Validate	ids []Blob, proofs []Proof, namespace Namespace	[]bool
Submit	blobs []Blob, gasPrice float64, namespace Namespace	[]ID

NOTE: The Namespace parameter in the interface methods is optional and used only on DA layers that support the functionality, for example Celestia namespaces and Avail AppIDs.

Implementations

The following implementations are available:

• celestia-da implements Celestia as DA.
• avail-da implements Polygon Avail as DA.

In addition the following helper implementations are available:

• DummyDA implements a Mock DA useful for testing.
• Proxy implements a proxy server that forwards requests to a gRPC server. The proxy client can be used directly to interact with the DA service.
