Light proofs

This section explains the lightproof object.

The block light proof structure contains:

• chain_id: identifies the chain this proof originates from,
• header: a block header,
• root: the merkle root at the block's height,
• bmproofpath: the merkle branches connecting the block ID with the last proven merkle root held by the contract.

Example of a light proof object:
