Yes, it is possible to remove a complete block from a network. There are times when only a specific portion of this online ledger is to be considered. There are default options and filters that can help us do this without making a lot of efforts.

No, in a blockchain network, it is not possible to simply remove a complete block. Blockchain operates on a decentralized and distributed ledger system, where each block is linked to the previous one through a cryptographic hash. Once a block is added to the chain, altering or removing it would require changing the information in all subsequent blocks, which is practically impossible due to the cryptographic security measures in place.

The immutability of the blockchain ensures that once a block is added, it becomes a permanent part of the ledger. If there’s a need to correct or update information, a new block is typically added to the chain with the updated information, maintaining the integrity of the entire ledger.
