Question

What is a chain reorganization?

Answer 1

A chain reorganization, in the context of blockchain technology, occurs when a blockchain network undergoes a change in its structure due to a sudden shift in the consensus algorithm or a fork in the blockchain. This can result in some previously confirmed transactions becoming invalid or being reversed. It is a complex process that can happen in decentralized networks like Bitcoin or Ethereum when there is a disagreement among network participants about the validity of certain blocks or transactions.

Answer 2

A chain reorganization, in the context of blockchain technology, occurs when a different version of the blockchain becomes the longest and most valid chain, often due to a significant change in the consensus protocol or a network fork. This can happen when there is a disagreement within the network about which transactions are valid, leading to the creation of multiple competing versions of the blockchain until consensus is reached.
