Add to Common for IBC lightproof DB

[DenisCarriere]

To Add

• [ ] map_blockroot_merkle
• [ ] map_header

Types

• [ ] BlockRootMerkle iterator
• [ ] BlockHeader iterator

Data required

• block.number
• block.id
• block.header
• block.blockrootMerkle

Code example consuming data

function processBlock(data){
    return rootDB.transaction(async () => {
      let block = JSON.parse(JSON.stringify(data.block, null, "  "));
      if (data.step === "STEP_IRREVERSIBLE") {
        lib = block.number;
        statusDB.put("lib", block.number);
      }
      else { //if STEP_NEW
        let date = (new Date(parseInt(block.header.timestamp.seconds)*1000)).toISOString().replace('Z', '');
        if (block.header.timestamp.nanos) date = date.replace('000', '500')
        statusDB.put("lastBlockTimestamp", date); 
      }
      const blockMerkle = block.blockrootMerkle;
      blockMerkle.activeNodes.forEach((node,index) => blockMerkle.activeNodes[index] = toHex(node) );
      var buffer = serialize(block.id, blockMerkle.activeNodes);
      blocksDB.put(block.number, asBinary(buffer));
    });
  }
