      Sir jab apne nodes ki type btain to mera ek ques h :
      Ic trha to data centralized hogyaa bcoz hr node har data verify nai kr saktaa .like mining node ka data specialized h tooo wo light node k pas to ni hoga na
      While blockchain me data decentralized hota h
      ??

      Asalam o alaikum Sir
      Firstly want to tell that I already put 3 queries until lecture 5 but didn't get answers of them yet ….. kindly help me out in this regard as well .
      Further a question regarding lecture 6 is that
      In Blockchain all nodes connected in network but you said previously that any new entry or information simultaneously updates in all nodes ……my question is that then why is there connection between these nodes and what sort of further information these nodes exchange although all have updated information already?
      Thank you

      If a node goes offline then after some time rejoin the Blockchain then it will automatically synchronize the previous data? If all the nodes are not workable then what will happened to Blockchain?

    29. Haresh kumar on

      Blockchain nodes are network stakeholders and their devices that are authorized to keep track of the distributed ledger and serve as communication hubs for various network tasks . A blockchain node's primary job is to confirm the legality of each subsequent batch of network transactions , known as blocks .

      Janab, so far understood every bit of what you said. Now, as you adviced i think i must google a little on different kinds of nodes before i must watch the next.

    34. Nadhi Faizal on

    38. Suleman Mehmood on

      Thank you sir. Today the sixth lecture has been completed. What you have explained so far. Understood. Glad to hear today that your goal is to take non-technical people to the end as well. I hope the way you are explaining. Your goal will be fulfilled, in sha Allah
