    How many blockchains are there?

    There are hundreds, if not thousands, of blockchains. The number will continue to grow as blockchain technology is adopted and adapted to new use cases. In time, there could be hundreds of thousands or millions of chains in the same way that there are so many computer networks in the world today.

    Why is the blockchain immutable?

    A blockchain is immutable because (in simple terms):

    The ledger is append only.
    As opposed to a traditional database, which allows records to be inserted or edited, a blockchain only adds records to the end of the ledger.

    Records are linked together and cryptographically sealed with unique 'fingerpri... more

    "Digital dollars" have existed on balance sheets for years (although I think technically they are supposed to be backed by a physical representation)... What makes the current push for "digital dollars" and entities like Visa patenting the concept of concern to so many? I know...

    My 2 cents about the push for digital dollars is that the current crisis has taught us how our paper money is a source of confusion and strain because it is analog. Take for example the recent stimulus money and how difficult it was to reach people on time not to mention some money that went to dece... more

    Hi, Jack. Is there any specific charge that Blockchain has for changing a wallet address for a receiver of funds whose wallet address was older than two weeks since it had been and funds were not delivered? My name is Jack Brannon and I am located in Kennesaw, Georgia USA

    if the funds were never received then the transaction was incomplete and as such you shouldn’t pay any gas (funds) for that transaction. The said transfer funds should have returned to the senders wallet, which means you can send them again to a different wallet address if you wish, you only pay wha... more
