The other, much larger, consideration would be to modify every block before the one being manipulated because the hash values and timestamps would need to be updated. These security measures make such an attack resource-intensive and minimize the probability of success. Scalability is another challenge, as each node can support only a limited number of transactions. This can lead to heavy transaction loads taking several hours to be completed.
They are also managed by a set of decentralized nodes, removing the need for a central authority to control all the transactions. This immutability is why blockchains have gained popularity in industries such as finances and real estate.

Data storage
R3 Corda – the platform is mostly used for creating permissioned blockchain and can be easily integrated with an already existing system. You can see an example of a blockchain technology stack in the image below. Blockchain-enabled https://www.nextcryptocity.com/ identity would allow users to get credentials and use them to prove their identity to other organizations. The decentralized storage of information doubles the wins for both users and organizations.
By comparison, blockchain technologies are still in their early days. Some of the revolutionary blockchain frameworks are Enterprise Ethereum Alliance, Microsoft Coco Framework, and IBM/ Linux Hyperledger Fabric (22-24). Blockchain architecture is a digital ledger of all cryptocurrency transactions.
