What is Hard Fork Combinator?

After a hard fork has taken place, a tool called a hard fork combinator (originally created by IOHK) is used to combine protocols, especially on the Cardano blockchain. A hard fork often takes place to execute blockchain improvements. It necessitates multi-partner signatures and typically affects some protocol characteristics.

Hard forks typically result in some downtime on the blockchain, which interferes with user interaction and transaction processing. Implementing a hard fork on the live blockchain is another option, however, this may compromise the integrity of the network. For instance, the 2017 Bitcoin hard fork led to the chain’s division and the creation of Bitcoin Cash (BCH). Eventually, this had an impact on the interests of traders and investors.
