Forkless upgrade refers to a method of updating a blockchain without creating a separate version or branch. In many cases, blockchain upgrades require a “fork,” which splits the blockchain into two distinct paths. This can lead to confusion, disagreements within the community, or the creation of new currencies.With a forkless upgrade, changes are implemented directly into the existing blockchain, allowing all users to seamlessly transition to the new version. This method is beneficial because it maintains network unity, avoiding fragmentation and the need for holders to choose between different versions.Forkless upgrades typically involve changes that do not require altering consensus rules or the underlying mechanics of the blockchain. Instead, they often focus on enhancing performance, improving security, or adding new features in a way that is universally accepted by the network participants.Overall, forkless upgrades promote stability and cohesion within the community, ensuring that everyone continues to operate on the same version of the blockchain without the complications that can arise from forking.
