Chain Reorganization

Chain reorganization in blockchain allows node operators to replace and adopt new blocks, ensuring the long chain of data remains constant. Blockchain consists of strings of blocks, connected within a distributed ledger. Each block in turn comprises hundreds of thousands of transactional data.

Chain reorganization is more common in busier blockchains such as Bitcoin (BTC) or Ethereum (ETH) where multiple nodes are required to create a new block at the same position at the same time. Under such circumstances, the node that has taken a shorter follow-up chain goes with chain reorganization. This, in turn, allows all the node operators to have the exact copy of the ledger.
