Once records are submitted on a Blockchain, can they be altered?a)Yes ...
, records on a Blockchain can be altered, but it is difficult and requires a majority consensus of the network participants. This is because each block in the chain contains a unique cryptographic hash that is based on the previous block's hash, making it very difficult to alter any block without invalidating the entire chain. Additionally, the use of a decentralized network makes it difficult for a single entity to control or manipulate the data on the Blockchain.
