Types

type DataAvailabilityHeader

type DataAvailabilityHeader struct {
	// RowRoot_j 	= root((M_{j,1} || M_{j,2} || ... || M_{j,2k} ))
	RowRoots [][]byte `protobuf:"bytes,1,rep,name=row_roots,json=rowRoots,proto3" json:"row_roots,omitempty"`
	// ColumnRoot_j = root((M_{1,j} || M_{2,j} || ... || M_{2k,j} ))
	ColumnRoots [][]byte `protobuf:"bytes,2,rep,name=column_roots,json=columnRoots,proto3" json:"column_roots,omitempty"`
}

DataAvailabilityHeader contains the row and column roots of the erasure coded version of the data in Block.Data. Therefor the original Block.Data is arranged in a k × k matrix, which is then "extended" to a 2k × 2k matrix applying multiple times Reed-Solomon encoding. For details see Section 5.2: https://arxiv.org/abs/1809.09044 or the Celestia specification: https://github.com/celestiaorg/celestia-specs/blob/master/src/specs/data_structures.md#availabledataheader Note that currently we list row and column roots in separate fields (different from the spec).
