How to verify the blockchain from headers with bitcore

Bitcore
#1

Once I connect to the bitcoin p2p network using bitcore-p2p and requesting the headers from the peers I end up with a large JSON containing several blockHeaders.

From this I would like to verify the different blocks. If I am correct I would have to perform the following steps:

  • Verify the hash from the previous block is indeed the equal to this block’s blockHeader.prevHash
  • Recompute the block hash using the blockheader version, prevHash, merkleRoot, time, bits and nonce
  • Verify the computed hash is indeed the hash that was send by the peer
  • Verify the headers using validTimestamp() and validProofOfWork()

Could anyone tell me if the above steps seem valid? I Also I am wondering or computing the block hash from the blockHeader has been implemented in bitcore-lib?
