How do we add a new block to a chain? Empty How do we add a new block to a chain?

Post by justme1984 on Sat Dec 16, 2017 5:37 am

Let's say, this Blockchain has 4 nodes, and consensus has been reached to accept a new block, thus, we need to add the new block to the chain on 4 nodes. For data immutability, do we need to verify hashed data of all blocks in a chain starting from genesis block before we add the new block (yes, we know how to find hash of the last block)?

Thanks in advance.
