Soft Fork

A soft fork is a backward-compatible upgrade to a blockchain protocol. This means that nodes that have not upgraded to the new version can still process transactions and participate in the network, as the new rules are more restrictive than the old ones.

Because the old nodes still recognize the new blocks as valid, the network does not split into two separate chains. Soft forks are often used to implement new features or improve security without forcing all users to upgrade immediately.

However, they can be more complex to design because they must fit within the constraints of the existing protocol. If a significant portion of the network does not adopt the new rules, the security of the soft fork may be compromised.

They are a common tool for protocol evolution, balancing the need for change with the desire to maintain network unity. Understanding the distinction between soft and hard forks is crucial for market participants who need to prepare for protocol changes.

It represents a conservative approach to network governance.
