Where is Blockchain data stored?
Blockchain is decentralized and hence there is no central place for it to be stored. That’s why it is stored in computers or systems all across the network. These systems or computers are known as nodes. Each of the nodes has one copy of the blockchain or in other words, the transactions that are done on the network.
Who owns the Blockchain?
IBM. What it does: As mentioned earlier, IBM is the largest company in the world embracing blockchain. With over $200 million invested in research and development, the tech giant is leading the way for companies to integrate hyperledgers and the IBM cloud into their systems.
